Definitions

  • the present invention relates to a screen cloth ele ⁇ ment and a screen cloth for making such a screen cloth element.
  • a very common type of screening machine has a screen frame, in which a number of screen cloth elements are mounted after one another and most often in overlapping relationship to provide agitation of the screening mate- rial during the screening operation, using simultaneous vibration of the screen cloth of the screening machine.
  • the different screen cloth elements are de ⁇ signed with a rigid frame which serves to hold a screen cloth of elastomeric material, or other material, in a tensioned state.
  • the rigid frame sometimes also has crossbars for additionally stiffening the screen cloth.
  • the rigid frame and the optional crossbars are generally integrated in the screen cloth material and sometimes form projecting beams on the underside of the screen cloths.
  • the screen is formed of screen plates of a brittle ceramic material or any other wear-resistant rigid, brittle material.
  • the screen plates are held in place by rubber strips which not only retain the rigid plates by yielding resiliently during mounting while the plates are depressed to their mounting positions, but also serve as elastic dampers to prevent the screen plates, consisting of brittle mate ⁇ rial, from cracking during the screening operation.
  • the rubber strips yielding resiliently to make room for the screen plates.
  • This resilient mounting or damping also results in reduced wear, in that the plates yield when subjected to heavy impacts from the screening material.
  • One object of the present invention therefore is to meet these requirements.
  • Another object of the inven ⁇ tion is to enable an extended time of use for such screen cloth element portions as have not been completely worn down during the screening process, so that these portions can be used several times and only the worn portions of the screen cloth elements are exchanged.
  • a special object of the invention is to further de ⁇ velop the advantageous screen design with overlapping screen cloth elements which is the subject matter of SE- B-460,340 and its counterparts EP-B-0 364 541 and US-A- 5,085,324.
  • detachable screen cloths which are fixed on a screen cloth element having a rigid mounting frame and intended to be fixed in the screen frame of a screening machine.
  • the detachable screen cloths have a rigid screen cloth frame which pref- erably is at least partially surrounded by elastomeric material.
  • a laterally open guide device in the rigid mounting frame of the screen cloth element is designed for sliding engagement with the screen cloth during the insertion thereof into the guide device and is further designed during screening to prevent relative movements between the screen cloth and the screen cloth elements in directions making an angle with the plane of the screen cloth. For mounting and dismounting the screen cloths, these are inserted laterally in or drawn laterally out of the remainder of the screen cloth elements like a drawer.
  • the invention also makes it possible to optimise the choice of material for the different parts of the screen cloth elements, such that the rigid frame of the screen cloth elements, for example, is integrated in an abrasion-re ⁇ sistant rubber material having properties that are espe- cially well suited for forming the mounting parts of the screen cloth elements, while a different material is se ⁇ lected for the exchangeable screen cloths, so that these are given optimum properties for the intended screening work. It is thus possible to choose a harder elastomeric material for the mounting parts of the screen cloth ele ⁇ ments and a softer elastomeric material for the exchange ⁇ able screen cloths if a sticky material is to be screen ⁇ ed.
  • the exchangeable screen cloths can thus be formed from a material having optimum proper ⁇ ties for the screening operation, while the rest of the screen cloth element may be formed from a material having optimum properties for the mounting and the retention of the screen cloths.
  • Another major advantage of the screen cloth elements according to the present invention is that the operator of a particular screening machine is offered a substan ⁇ tial amount of freedom for choosing the screening mate- rial in one and the same machine, since he may in a sim ⁇ ple manner replace one screen cloth surface with another while maintaining the majority of the screen cloth ele ⁇ ments of the screening machine intact.
  • exchange ⁇ able screen cloths of different types it is thus possi- ble to screen all sorts of screening materials, from sticky materials to coarse and fine material.
  • the design of the apertures in the screen cloths can therefore be varied irrespective of the remaining parts of the screen cloth elements, and the exchangeable screen cloths may be designed as wire screens or foraminated screens.

DESCRIPTION OF THE PREFERRED EMBODIMENTS As appears from Fig. 1, the screening machine has a screen frame 10, in which a number of screen cloth ele- ments 11 according to the invention are mounted after one another.
  • the screen cloth elements 11 comprise a rigid mounting frame in the form of a mounting part 12 and a rigid reinforcing core 13 provided therein.
  • the reinforc ⁇ ing core 13 is integrated in an abrasion-resistant elas- tomeric material which may consist of natural or synthe ⁇ tic rubber or plastic.
  • An exchangeable screen cloth 14 is mounted in the mounting part 12 in a manner which will be described in more detail hereinafter.
  • the ends of the successively mounted screen cloth elements are overlapping, so that the downstream end, as seen in the screening direction (arrow 15), of one screen cloth element is positioned on top of the upstream end of the following screen cloth element.
  • the underside of the mounting part 12 adjacent its downstream end has a projection 16 with an undercut groove 17.
  • the components 16 and 17 form one part of snap-lock means for locking the screen cloth element to the screen frame.
  • the other part of the snap-lock means consists of a thickened edge portion 18 on a carrier ele- ment 19 included in the screen frame.
  • This carrier ele ⁇ ment has a projecting flange or abutment surface 20.
  • the upstream end 21 of the following screen cloth element rests on this abutment surface.
  • the relative dimensions of the carrier element, the snap-lock means and the screen cloth elements are such that the upstream end of the following screen cloth element is clamped between the abutment surface 20 and the projecting edge portion 22 of the preceding screen cloth element.
  • the upstream end of the uppermost screen cloth element rests on an abutment sur- face 23 on the screen frame 10 and is depressed against this abutment surface by a clamping element 24.
  • the clamping element 24 also retains a sliding surface 25, along which the material to be screened passes down to the screen cloth elements.
  • the frame 13 is placed in a vulcan ⁇ ising mould, such that it will abut on supporting bosses in five places where the vulcanising mould has inwardly extending abutment surfaces forming recesses on the un- derside of the mounting part or holder 12 to be formed.
  • the recesses 28 are visible in Fig. 5 and are disposed on the inside of the longitudinal edge stiffen ⁇ ing means of the holder.
  • the fifth recess is a narrow groove 29 at the upstream end of the holder 12, this re- cess being illustrated in more detail in Figs 3 and 4.
  • a screen cloth element comprises a holder part or mounting part 12 and a screen cloth 14 insertable therein.
  • the screen cloth 14 consisting of elastomeric mate- rial, has a rigid screen cloth frame 30 which is inte ⁇ grated in the elastomeric material and encircles the screen cloth 14 and which may advantageously have one or more crossbars 31, since the screen cloth element and the screen cloth have a substantial length, as seen in the screening direction (arrow 15) .
  • the crossbars 31 serve to stiffen the screen cloth and reduce the tendency of the screen cloth surfaces to flutter when the screen cloth 10 is vibrating.
  • the screen cloth 14 is thus formed as a separate element.
  • the part 12 has been designed with a guide device 32, 33, which is laterally open relative to the screen cloth element. This guide de ⁇ vice is designed for sliding engagement with the screen cloth during the insertion thereof into the holder part
  • the screen cloth 12 is also designed to prevent relative movements be ⁇ tween the screen cloth 14 and the holder part 12 of the screen cloth element in directions making an angle with the plane of the screen cloth, especially at right angles thereto. Since the screen cloths are inserted in the holder part transversely of the screening direction of the screening machine, the screen cloths will be pre ⁇ vented from moving along the guides, once the screen ele ⁇ ments have been mounted in the screen frame of the screening machine. Thus, the screen frame prevents move ⁇ ments in the transverse direction.
  • the rigid frame or holder part 12 advantageously comprises a rigid frame core 13 and a coating of elas- tomeric material partially surrounding the core. Advanta ⁇ geously, the guide device is designed in this coating, as shown in the drawings.
  • the guides 32, 33 of the guide device are advanta ⁇ geously so located in the holder part 12 of the screen cloth element as to be protected against contact with the screening material.
  • the guide 32 at the up ⁇ stream end of the screen cloth element is so positioned that this guide 32 and a portion of the screen cloth 14 are concealed under and protected by the projecting por- tion 22 of the immediately preceding screen cloth ele- ment, as appears from Figs 1 and 2.
  • the guide 33 is protected by the screen cloth 14 being designed with a projecting por ⁇ tion 34 which is recessed in the holder part 12 and is flush with the upwardly facing surface of the projecting portion 22 of the holder part.
  • the projecting portion 34 may either end just after the guide 33, as shown in the embodiment according to Fig. 1, or extend as far as the end of the projecting portion 22, as shown in the embodi- ment of Fig. 2.
  • the screen cloths 14 For mounting and dismounting the screen cloths 14, these are laterally inserted in the holder part 12 of the screen cloth elements, as indicated by arrows 35 in Fig. 6.
  • the screen cloths 14 then slide along the guides 32, 33, the insertion and extraction of the screen cloths being facilitated by the position of the rigid frame 30 of the screen cloth in the elastomeric material close to the portion of the screen cloth elastomeric material forming the guide surface which the guides 32, 33 of the holder part 12 engage.
  • the rigid frame 30 of the screen cloth 14 is disposed straight above the rigid frame 13 of the holder or mounting part 12 to be sup ⁇ ported thereby.
  • the separate, in- serted screen cloth will not as easily be depressed or deflected by the screening material placed thereon.
  • Figs 10-13 show another embodiment of a screen cloth element and a screen cloth according to the present in ⁇ vention.
  • the screen cloth is designed as a wire screen 40.
  • the wire screen has a rigid frame element 30 of metal which encircles the screen.
  • This screen ele ⁇ ment is a substantially completely embedded in elasto ⁇ meric material in the same way as in the case of the screen cloths 14 in the previously described embodiments of the invention.
  • undercut grooves 41 are provided in the underside of the elastomeric material on the inside of the frame element 30.
  • the grooves 41 are intended to cooperate with transverse carrier rods 42 of metal. These carrier rods in turn are interconnected by the wires 43 of the wire screen.
  • the screen wires 43 are wound one turn about each carrier rod. At the ends of the wire screen, the screen wires ex ⁇ tend up to the inside of the elastomeric material sur- rounding the frame element 30. If so desired, the free ends 44 of the screen wires 43 may extend into downward ⁇ ly-facing recesses in the elastomeric material.
  • the carrier rods 42 will be confined in their undercut grooves 41, once the carrier rods with the screen wires 43 disposed thereon have snapped in place in the grooves 41 and the screen cloth has been laterally inserted in the holder part 12.
  • the screen wire elements need not necessarily be designed as shown in Figs 10-13.
  • the screen wires 43 may instead ex ⁇ tend straight from end to end and rest on the carrier rods 42 and be welded thereto.
  • the screen wires 43 may be fixed directly on the frame element 30 on the screen cloth. In such a case, the screen wires 43 may be pretensioned, if so desired.
  • Fig. 14 shows another embodiment of a screen cloth 50 according to the invention.
  • the general shape of the screen cloth is the same as that of the screen cloth 14 in the embodiment shown in Figs 1-9.
  • the screen cloth 50 has a guide 51 on its upstream end and a guide 52 at its downstream end.
  • the upstream end guide 51 is gable-roof- shaped in cross-section and comprises an upper guide sur ⁇ face 53 and a lower guide surface 54, the crest of the gable-roof-shaped guide being disposed at a greater dis- tance from the top surface of the screen cloth than from the bottom surface thereof for the reason explained be ⁇ low.
  • the roof surface 53 is inclined at an acute angle to the top surface and extends towards the upstream end of the screen cloth.
  • the downstream guide surface 52 is shaped as a groove in the downstream end of the screen cloth 50.
  • this groove has its upper wall sur ⁇ face 56 disposed in parallel with the top surface of the screen cloth.
  • the lower wall surface 55 of the groove or guide surface 52 is disposed at an acute angle to the bottom surface of the screen cloth, extending towards the upstream end of the screen cloth.
  • the bottom of the groove is disposed at a greater distance from the bottom surface of the screen cloth than from the top surface thereof for the reason explained below.
  • the screen cloth has a projecting portion 57 corresponding to the projecting portion 34 in the embodiment shown in Figs. 1-9.
  • the screen cloth of Fig. 14 has a rigid frame 58 corresponding to the frame 30 in the embodiment shown in Figs 1-9.
  • the rigid frame 58 has a flange 59 projecting in the downstream direction and into the coating of abra ⁇ sion-resistant elastomeric material surrounding the frame or core 58.
  • This flange 59 is either integral with or rigidly attached to the frame 58.
  • the purpose of this flange 59 is to reinforce the tip of the elastomeric ma ⁇ terial between the groove surface 55 and the bottom sur ⁇ face of the screen cloth in order to improve the function of the guide surface.
  • the mounting part 60 of the screen cloth element shown in Fig. 15 has its guide surfaces 61 and 62 at the upstream end and downstream end, respectively, shaped complementary to the guide surfaces 51 and 52, respec- tively, of the screen cloth 50.
  • the upstream guide surface 61 is shaped as a groove having a gable-roof- shaped cross-section with an upper wall 63 and a lower wall 64.
  • the mounting part 60 has a support sur ⁇ face 69 for supporting the screen cloth mounted in the mounting part 60. The bottom of the groove 61 is disposed closer to the support surface 69 than to the upper sur ⁇ face of the screen cloth element.
  • the guide surface 62 on the downstream end of the mounting part is formed as a flange having a substan- tially triangular cross-section.
  • the lower face 65 of this flange is disposed at an acute angle to the support surface 69 and extends in the upstream direction from the support surface.
  • the upper surface 66 of the flange 62 is parallel to the upper surface of the mounting part 60 or the screen cloth element and is closer to that surface than to the support surface 69.
  • the mounting part 60 has a rigid core or frame 67 corresponding to the frame 13 of the embodiment shown in Figs 1-9. Like the frame 58 of the screen cloth 50, this frame 67 has a flange 68 extending into the tip of the downstream guide surface 62 in order to stiffen this tip and improve the function of this guide surface both in connection with the mounting of the screen cloth 50 in the mounting part 60 and in connection with the use of the screen cloth element in a screening machine.

  • Another advantage is that stock-keeping is facilitated by the small screen cloth dimensions as compared with the whole screen cloth elements. The re ⁇ cuted dimensions are also advantageous in terms of manu ⁇ facture, transportation and storage.
  • the exchangeability and the ease with which exchanges can be made are also major advantages, in that it is easy to switch between different types of screening operations in the screening machine, i.e. by a simple exchange it is possible to al ⁇ ter the mesh size or the quality of the material in the very screen cloth surface so as to achieve optimum condi ⁇ tions for a large variety of screening material grades.
  • the invention is particu ⁇ larly advantageous in connection with the type of screens described with reference to the embodiment.
