Definitions
- the invention relates to a device for the thermal treatment of a textile web, in particular a drum dryer or thermal bonder, according to the preamble of claim 1, and a method for the thermal treatment of a textile web.
- the thermal treatment of a textile web of nonwoven or nonwoven fabric includes hot air drying or hot air solidification in a flow-through, in which a heated gas, such as air, flows through the web and thereby dried or solidified.
- a heated gas such as air
- For drying or solidification of textile webs dryer are known in which one or more drums are arranged in a housing. Through an opening in the dryer chamber, a textile web is fed to the dryer by looping around the drum to a large extent of the circumference and then guided around the next drum and / or discharged from the dryer chamber again. Usually, the fresh air is supplied through this opening, which is heated within the dryer chamber and mixed with the circulating air, so that they can absorb the highest possible proportion of moisture.
- the mixture of circulating air and fresh air flows through the web, at least partially absorbs the moisture of the web and is discharged through the interior of the drum again. Due to the air supply, for example via the opening in the dryer chamber, which extends over the entire working width, and the air discharge, which takes place at one end side of the dryer, results in uneven flow conditions within the dryer, whereby the web over its width with different air velocities, Air quantities and air quality is flowed through. The web can therefore have a different quality level over its width, which is undesirable. Furthermore, the energy conditions of the dryer (including flow velocity) always have to align with the most unfavorable situation in terms of flow, whereby the energy consumption is higher than necessary.
- the object of the invention is the development of an apparatus and a method for the thermal treatment of a textile web, in particular in a drum dryer or thermal bonder, comprising at least one flow-through drum with a perforated lateral surface, the jacket is at least partially wrapped by a web, wherein a heated gas, the web and flows through the jacket of the flow drum.
- the invention includes the technical teaching that within the flow drum an air guide cylinder is arranged with a plurality of openings, through the interior of which the heated gas is withdrawn, wherein the air or gas permeability of the air guide cylinder is adjustable. Via the adjustable air or gas permeability of the air guide cylinder, the air flow in the flow space can be influenced, which in turn has an influence on the uniformity of the flow through the web.
- the air or gas permeability of the air guide cylinder is adjustable along its longitudinal axis.
- the uneven air flow which flows through the inlet area over the entire longitudinal axis and is drawn off at one end face on the suction, can be made uniform in the flow space.
- the air or gas permeability of the air guide cylinder is adjustable over its circumference. Due to the adjustability over the circumference of flow differences can be compensated, for example, caused by a change in the pressure losses of the goods as a result of the process. Alternatively, general circumferential flow irregularities can be compensated and corrected.
- At least one cover body is arranged on or within the air guide cylinder, with which the openings of the air guide cylinder are at least partially closed.
- the air or gas permeability of the air guide cylinder can be adjusted along its longitudinal axis or over its circumference.
- the Luftleitzylinder is divisible into sections, the air or gas permeability of each section is separately adjustable.
- the sections are arranged along the longitudinal axis of the air guide cylinder.
- the air or gas permeability of the air guide cylinder for example, be smaller in the central region, as in the edge region.
- the inventive method for the thermal treatment of a textile fabric web comprising at least one through-flow drum with a perforated jacket, the jacket is at least partially wrapped by a web, wherein a heated gas flows through the web and the jacket of the throughflow drum, characterized in that within the throughflow drum an air guide cylinder is arranged, via the interior of which the heated gas is withdrawn, wherein a flow space is arranged between the air guide cylinder and throughflow drum whose flow conditions can be changed by the adjustability of the air or gas permeability of the air guide cylinder. Due to the more even flow of air in the flow space, the flow through the web is optimized, whereby the energy costs of the dryer or Thermobonders can be reduced.

- Section of an air guide cylinder Section of an air guide cylinder.
- Fig. 1 shows a hot-air operated dryer in omega construction according to the prior art.
- the web 1 to be dried runs in the inlet region 4 via a deflection drum 2 in the dryer, wraps around the air permeable throughflow drum 5 in a clockwise direction and runs over a further deflection drum 3 from the dryer again.
- the flow-through drum 5, as well as the two deflection drums 2, 3 are arranged in a housing 7, in which hot air is introduced via means not shown.
- the hot air flows through the web 1, this dries it and is the front side by a on one or the end faces of the flow-through arranged suction, for example, the suction 8 in Figure 2, sucked by a fan, not shown.
- the flow-through drum 5 is placed under negative pressure, so that different flow conditions occur in the dryer.
- an air-guiding cylinder 10 which is at least partially air-permeable is arranged concentrically to the longitudinal axis 6 of the through-flow drum 5 inside the throughflow drum 5, which is cylindrical, the air or gas permeability of the air guiding cylinder 10 being adjustable.
- the lateral surface 1 1 is executed, which has a plurality of openings 13.
- the Luftleitzylinder 10 is similar to a perforated tube constructed and arranged concentrically with a constant distance to the flow-through drum 5. Between the flow-through drum 5 and the air-guiding cylinder 10, a cylindrical circumferential flow space 15 is thus formed, in which the air flow 16 is made uniform by the adjustable air or gas permeability of the air-guiding cylinder 10.
- the size or the volume of the flow space 15 is essentially formed by the differences in diameter of the through-flow drum 5 to the air-guiding cylinder 10.
- the diameter of the air guide cylinder 10 is preferably between 20 and 80% of the diameter of the flow-through drum 5.
- the air guide cylinder 10 also extends over the entire length of the flow-through drum 5 and preferably ends with the same end faces 9a, 9b as the flow-through drum 5.
- the Air or gas permeability of the air guide cylinder 10 is made by a plurality of openings 13 or holes in the circumferential surface 1 1 of the cylindrical tubular body of the air guide cylinder 10, wherein the permeability of the openings 13 are adjustable in size, including a complete closability.
- the openings 13 are preferably round or oval or elliptical, wherein with oval or elliptical openings 13 whose longitudinal axis is preferably aligned parallel or perpendicular to the longitudinal axis 6 in order to achieve a high and accurate adjustment of the permeability by moving or twisting a cover body.
- the plurality of openings 13 can also be distributed uniformly over the entire length and over the entire circumference of the air guide cylinder 10.
- the openings 13 are arranged in the edge region 14 of the lateral surface 1 1 and thus go very close to the end faces 9a, 9b of the flow-through 5th
- the adjustment of the air or gas permeability can be carried out by a covering body in the form of a second cylinder, not shown, or by individual shells or rounded segments, which are arranged within the air guide cylinder 10, for example, with an identical number, shape and size at the openings 13 is. Over a small axial or radial displacement of the inner cylinder or the shells or rounded segments, the air or gas permeability between 0 and 100% is adjustable.
- the Luftleitzylinder 10 may be formed as an approximately cylindrical polygon with a plurality of along the longitudinal axis 6 flat surfaces, the openings 13 are closed by disposed within the Heilleitzylinders 10 sliding cover body in the form of sheets which are longitudinal or transverse to the longitudinal axis 6 to a predetermined amount are displaced.
- This has the advantage that the Air or gas permeability of the air guide cylinder 10 is unevenly adjustable over the circumference. Due to the adjustability over the circumference, flow differences can be compensated, which, for example, results from a change in the pressure losses of the goods as a result of the process. In principle, flow irregularities over the circumference of the air guide cylinder can be corrected.
- the Luftleitzylinder 10 have the maximum air or gas permeability, and depending on the width of the web or the textile fibers to be processed either along its longitudinal axis or over its circumference in further operation reduce the air or gas permeability, to influence the air flow 16 in the flow space 15.
- the air guiding cylinder 10 is divided along its longitudinal axis 6 into a plurality of sectors (12a-12d).
- each sector (12a, 12b, 12c, 12d) can be adjusted uniformly with respect to its air or gas permeability over the circumference, but along the longitudinal axis 6.
- the embodiment of Figure 2 shows an air guide cylinder 10 which has been divided into four sectors (12a, 12b, 12c, 12d).
- the number of sectors may be from 2 to 10, for example.
- each of the ten sectors could have a length of 0.5 m.
- Each sector can be set separately for its air or gas permeability independently of the other sectors.
- the air or gas permeability in the edge region of the air guide cylinder 10, so in the region of the end faces 9a, 9b, are increased to the Air flow in the flow space 15 at the edges of the web 1 to increase.
- An alternative adjustability may provide to increase the air or gas permeability of the air guide cylinder 10 along the longitudinal axis 6 of the suction 8 to the end face 9a, since in the suction area the greatest pressure difference is applied and thus in the flow space 15, the air flow is very unequal.
- the air guide cylinder 10 may be divided into four sectors (12a, 12b, 12c, 12d) as an air-permeable, approximately cylindrical tube having a plurality of openings 13 on the circumference.
- a cover body in the form of an inner separate tube for opening or covering the openings 13 can be arranged.
- These inner separate tubes can be moved along the longitudinal axis 6, or alternatively, which is structurally easier to implement by an amount slightly larger than an opening 13 about the longitudinal axis 6 are rotated.
- the air-guiding cylinder 10 may be an approximately cylindrical polygon with a plurality of flat surfaces along the longitudinal axis 6, the openings 13 of which can be closed by sliding plates arranged on or within the air-guiding cylinder 10.
- the air guiding cylinder 10 is divided into a plurality of sections (12a, 12b, 12c, 12d), here for example 4 sections, each of which can be adjusted separately with regard to the air or gas permeability. Each section extends over the entire circumference of the air guide cylinder 10, but only over a partial area along the longitudinal axis 6.
- the cylindrical flow-through drum 5 is shown in a perspective sectional view, within which the cylindrical Lucasleitzylinder 10 is arranged.
- the diameter of the air guide cylinder is about 60% of the diameter of the fürströmtronnnnel 5.
- the Lucasleitzylinder 10 extends along the longitudinal axis 6 to the end faces 9a, 9b, wherein the lateral surface 1 1 has on both sides in each case an edge region 14 without openings 13.
- This embodiment may be advantageous if the through-flow drum 5 is designed for a web 1 of maximum width, but at the same time narrower webs 1 are to be processed and the through-flow drum 5 is optionally coverable in the edge regions.
- the cover body which should close or cover the openings 13 for influencing the air or gas permeability, are not shown in this figure for better illustration.
- perforated or perforated surface is meant the area in which the respective lateral surface is perforated or perforated. From this ratio, the dimension of the Luftleitzylinder depending on the drum shell. This also results in the size or the volume of the flow space, which is decisive for the effect of homogenization.
- the air flow 16 is also made uniform by the fact that the ratio between the free surface of the jacket of the throughflow drum 5 and the free surface of the air guide cylinder is in the range of 2 to 10.
- the free surface or the free cross section is the relative free hole area (air passage) in%. Due to the high speed with which the air flow 16 is sucked through the openings 13 of the air guide cylinder 10 to the fan, a pressure change occurs within the flow space 15, whereby the air flow passes more uniformly through the web 1 in the flow-through drum 5.
- FIG. 4 shows a cutout on the surface of an air guide cylinder 10, which is designed as a polygon with a plurality of flat surfaces.
- the same arrangement results in a cylindrical Beerleitzylinder, which may consist of rounded sheet metal and in which the openings of the sections can be covered by individual shells or rounded segments.
- an edge region 14 is arranged which has no openings 13.
- subregions of an air guide cylinder 18a, 18b and 18c with a multiplicity of openings 13 which can be covered by covering bodies arranged in the form of three flat or rounded sheets 17a, 17b, 17c of different widths A, B, C.
- the cover body can also be arranged below the subregions of the air guide cylinder.
- Each cover body ie each sheet 17a, 17b, 17c, is part of a circumferential section 12a, 12b, 12c.
- Each circumferential section 12a, 12b, 12c therefore also has the width A, B or C over the entire circumference.
- the metal sheets 17a, 17b, 17c can be followed by further metal sheets for covering a further circumferential section, with the last section ending at an edge region or directly at an end side.
- a subregion of an air guide cylinder 18a, 18b, 18c is arranged, of which only the subregion 18c is visible in this illustration.
- This portion 18c is also formed as a sheet and has the same openings 13 as the plate 17c, with which the cover is made.
- the size and the distance of the openings 13 from the sheet 17c and the portion 18c are preferably the same.
- the sheets 17a, 17b, 17c can be displaced along an arbitrarily arranged guide 19 in order to completely open the openings 13 of the partial areas 18a, 18b, 18c, to close them completely or to close or open them in a partial area.
- the displacement of the sheets 17a, 17b, 17c is therefore at least a clear dimension of the opening thirteenth
- the adjustability of the cover body can basically be done manually or automatically.
- an unillustrated linkage, lever or spindle system may be arranged in the air guide cylinder 10, with which the cover body are axially or radially movable.
- the linkage, lever or spindle system in turn can be actuated by means of an electric motor, hydraulic or pneumatic drive.
- the adjustability of the cover body can be regulated depending on the operating conditions. For example, when starting the maximum air or gas permeability of the air guide cylinder 10 can be adjusted by a complete opening of the openings 13. After the flow level has stabilized in the flow space 15, the flow velocity in individual regions of the flow space 15 can be influenced by targeted partial or complete closing or covering of individual openings via individual sections, which has an influence on the flow through the material web around the flow-through drum.
- sensors are advantageously arranged in the flow space, whose data from a Data processing can be used to control the flow of air.
- the sections 12a, 12b, 12c can have a different width A, B or C along the longitudinal axis of the air guiding body.
- the sum of the widths A, B, C gives along the longitudinal axis of the air guide cylinder 10 the perforated area with the width X.
- This width X is dependent on the working width of the dryer and the drum diameter.
- each section 12a, 12b, 12c may have a different size and number of openings 13.
- each section 12a, 12b, 12c can separately close the openings 13 separately over its circumference and along the longitudinal axis 6 of the air guide cylinder, in order to influence the flow conditions.
- Each cover body, here in the form of the sheets 17a, 17b, 17c, is individually controllable in this embodiment, both along the longitudinal axis 6 or in the circumferential direction of the air guide cylinder (not shown).
- each section 12a, 12b, 12c can be closed separately with a covering body, at least in the longitudinal axis 6.
- the openings 13 of all portions 18a, 18b, 18c of the air guide cylinder and the Openings of the sheets 17a, 17b, 17c the same size.
- the air or gas permeability of each subarea 18a, 18b, 18c of the air guide cylinder is separately adjustable along the longitudinal axis 6 of the air guide cylinder 10.
- the openings are closed by the cover body (sheet 17a) arranged above 84%.
- the right portion 18c is opened with its openings 13 through the cover body arranged above it (plate 17c) to 90%.
- the air or gas permeability of the air guide cylinder 10 is thus variable along its longitudinal axis 6.
- the free surface that is to say the area of the maximum openings 13 to be flowed through, can be 8-30% of the surface of the partial areas 18a, 18b, 18c to be closed.
- the speed of the air flow 16 is influenced, on the other hand, the pressure level in the flow space 15. Both factors significantly influence the uniformity of the air flow 16 in the flow space 15.
- the air flow within the flow drum 5 can be made uniform by the air or gas permeability of the air guide cylinder 10 is adjustable over its length as well as over its circumference.
- the adjustability is achieved in that the air guide cylinder 10 has a plurality of openings 13 which are at least partially open or closed by means of at least one inside or on the Lucasleitzylinder 10 arranged cover body. Particularly advantageous is the division of the plurality of openings 13 on individual sections 12a, 12b. etc., which are separately closable in the longitudinal axis 6 of the air guide cylinder 10 and / or in the circumferential direction.
- the air or gas permeability of the individual sections can be adjusted via slidable perforated plates and thus a optimum uniformity of the flow over the surface of the flow-through drum 5 can be achieved.
- This adjustability takes place over the working width (perforated or perforated width) of the flow-through drum and over the circumference.
- the number of sections over the working width and over the circumference depends on the size of the flow-through drum.
- the sections may be distributed uniformly or non-uniformly over the surface of the air guide cylinder.
- the use of the invention is provided in particular in a drum dryer or thermal bonder.
