Definitions
- the invention relates to a plan sifter, in particular a square plan sifter and its structure with respect to the load-bearing elements.
- Such plansifters are used in particular for the screening of grist, semolina and / or flour-like products in the mill process technology, as well as for the sorting of various vegetable grains such as. B. wheat, rye or corn or generally for the separation of grain by different grain sizes.
- Plansifters especially large and square plansifters, are part of the current state of the art, e.g. B. for separating or sieving / classifying or classifying grain products
- a square plan sifter is known from WO 93/16815, which has a swing action which forces the plan sifter and all sieves to perform a circular movement, the plan sifter as a whole being suspended from bars in the usual way as a cantilever.
- the frame of such a plan sifter is designed as a supporting housing, which receives and laterally supports the sieve stack, with a housing base which forms a support base for the sieve stack and on its upward-facing rare walls.
- a plan sifter according to DE -PS 2256307 vertical clamping stacking devices whereby the forces of the vibration exciter are transmitted via vibration-stable ceiling and floor elements of rigid stacking frames.
- the stacking frames are each characterized by two vertical elements, each of which is arranged in a plane containing the center of gravity of the stack, to the longitudinal plane perpendicular to the longitudinal plane through the stack and the vibration exciter, and which are rigidly connected to the ceiling and floor elements of the stacking frames.
- the vertical elements form the vertical Edges of a parallelepiped-shaped vibrating frame, the vibrating bearings of the plan sifter being arranged on these vertical elements
- the object of the invention is to design a generic plan sifter in such a way that its manufacture of the supporting structure is noticeably simplified by further developed modular construction. Furthermore, within the limits set by vibration technology, the dead weight is also to be reduced and sanitation and accessibility are to be improved This object is achieved on the basis of the features of the characterizing part of claim 1
- the fact that the flow of forces can be realized via the supporting structure opens up further possibilities for modularization. The flow of forces is softer overall and a larger proportion of the flow of forces can be passed over the sieve stack in a function-enhancing manner.
- Such a supporting structure is apparently comparable only with the basic elements base, vertical support and cover with the prior art according to DE-PS 2256307, but not in the detailed version, since it is not covered by the fundamental principles of vibration engineering. In particular, the manufacture and assembly of the parts of the supporting structure is simplified.
- the plan sifter according to the invention consists of several double compartments in their supporting structure, which are laterally connected to each other and at the ends with Help be hung by
- the double compartments consist of a lid and a base, which are connected by vertical profiles and which form side compartments (each) with two compartments (sieve compartment). This eliminates or a separate frame structure for the bottom and lid can be omitted
- the side parts are positively and non-positively fastened, whereby the positive locking ensures tightness and thus sanitation.
- Cold insulation or hot bridging is avoided by further insulation.
- An air duct in the vertical profiles can cause the profile surface to heat up by flowing hot air through it, thereby Condensation is avoided. Such an option can be particularly useful for delicate products.
- the hot air flow can be provided by separation from the product flow or separately
- the sieve stacks can then be inserted and clamped, preferably in a form-fitting manner, into the supporting structure.
- the sieve stacks can be braced both conventionally and in a further embodiment of the invention using pneumatic means.
- An elastic, inflatable element is arranged in the space between the sieve stack and cover , which, when filled with air, ensures a defined, constant vertical tensioning and has the same sound-absorbing effect.
- bracing from the inside is easier and more space-saving.
- the outer side parts and also the doors consist of sandwich constructions or foamed elements, such sandwich elements being known as such, but not such an application.
- the doors are preferably positively and non-positively inserted and braced between two vertical profiles and are easy to use.
- Fig. 1 an exploded view of a plan sifter
- Fig. 2 shows a double compartment
- Fig. 3 is a sectional view of a compartment and a door
- the drive unit represents an unbalance drive with an oscillating motor in order to set the double compartments and thus the stacked sieves in an oscillating movement via the drive, which is common with such plan sifters.
- the plan sifter contains, as a square plan sifter, 5x2 sieve stacks (9) in this exemplary embodiment, analogous arrangements being possible from 1x2 sieve stacks (9) upwards.
- the load-bearing structure consists of five double compartments connected laterally to one another and four vertical supports 3 attached to the transverse sides.
- the double compartments themselves consist of a base 1 and a cover 2, which are connected by vertical profiles 5 and two compartments 4 with side panels 6 form.
- the drive unit is arranged in each case in the space between the double compartments, taking into account the number of double compartments.
- the side parts 6 with a foam sandwich construction are fitted into recesses 7 in the vertical profiles 5.
- recesses 8 of the vertical profiles 5 are in sieve stacks 9 arranged sieves inserted and braced A complete horizontal bracing of the sieve stack 9 is ensured by the inserted doors 10, which consist of side parts 6, which are contained in door profiles 15.
- the side parts 6 consist of metallic cover plates 12 (preferably aluminum) and an intermediate layer made of foam 13. Insulations (polymer insert) 14 in the vertical profiles 5 serve as cold bridges.
- the side parts 6 are only inserted into the recesses 7 and tensioned and glued with the aid of teachings.
- the continuous cavities in the vertical profiles 5 optionally serve as an additional air duct for warm air and prevent condensation.
- the vertical profiles 5 themselves can consist of aluminum profiles as is customary in the trade
- the frame of the door 10 is formed analogously to the formation of the vertical profiles 5, and the aforementioned also applies with regard to the connection to the door leaf (analog side part 6)
- the vertical profiles 5 themselves are connected to the base 1 and the cover 2 by screw connections, so that the required shape and strength is given and the power flow takes place as mentioned above.
- Base 1 and cover 2 are laser-cut and bent to give a shape before coating Cover elements (not shown) can be attached to the outer corner parts of the vertical profiles 5 in order to achieve flush, smooth outer contours of the plan sifter. The same applies to the upper and lower side edges.
- the side parts 6 can already be coated with the required paint or the like, so that further treatment before, during or after assembly can be omitted.
- a tubular element (not shown) arranged essentially on the sieve frame which, when filled with air or the like. Gases a defined, vertical bracing of the sieve stack 9 is made possible. There is a uniform clamping force that is measurable, which also increases operational safety.
- a vibration exciter can be arranged according to DE-PS 2256307; the screening process will also be carried out analogously.
- the drive is preferably preassembled as a subassembly and is mounted separately, which makes it possible to transport a plan sifter in subassemblies and to complete it comparatively easily on site.
