Definitions

  • the invention relates to a press for dewatering according to the preamble of claim 1. It is described in the following using the example of waste arising in waste paper processing, but is also applicable to other materials that can be dewatered by compression.
  • the waste paper mostly contains a certain proportion of contaminants which should be removed during processing for the purpose of reusing the waste paper.
  • a number of machines and processes are available for this purpose, which derive the waste paper for further processing as a good substance and the contaminants removed from it as a reject.
  • These rejects are usually deposited or, in special cases, processed into new products. Since waste paper is usually processed in an aqueous suspension, the rejects are highly water-containing, which makes them difficult to manipulate and considerably increases the costs of transport and landfill for their disposal.
  • the pressing treatment in the device according to the invention does not take place continuously but batchwise, very high forces can easily be exerted on the material. Only slight relative movements take place between the components transmitting the pressing force on the material and the material. If the pressing movement takes place at right angles to the direction of the initial conveying, the material is enclosed and can be compressed very strongly without a disadvantageously high force being transmitted to the components causing the initial conveying.
  • FIG. 2 shows a pressing device designed according to the invention.
  • a transport screw is used as the conveyor device 7.
  • the material A passes through an opening 11 into the volume 8 in which the transport screw is located.
  • the volume 8 is limited by a jacket 10 provided with holes 9, which is cylindrical here.
  • the material is already pre-dewatered by gravity as well as by any compression that may occur during transport.
  • the water W runs through the openings 9 of the jacket 10 into a drainage box 17. After passing through the conveying section 5, the material reaches the area of the discharge 12.
  • The, for example, hydraulically operated servomotor is supplied with a pressure medium via pipe socket 21. By pressing further water W 'gets into the drainage box 17.
  • servomotors according to FIG. 11 or other devices generating pressure forces are also conceivable.
  • the material A '' which is now very drained, can fall out of the device or be conveyed out by the following material.
  • the screw conveyor is driven by a drive motor 16 which - as indicated schematically - sets the shaft of the screw conveyor in rotation via a belt or the like.
  • the same pressing device is shown in FIG. 3 with the upper plate 23 omitted as a view from above with a view of the housing 15 and the inlet opening 11.
  • Fig. 4 shows a rough schematic representation of the deformation of the compressed material A 'to the pressed plug-shaped material A' '.
  • the representations a, b, c show the course of the pressing process, namely (a): unpressed, the pressing elements 13 and 14 are moved against the waste A '; (b): With the help of relatively large forces K and K 'the waste is pressed and accrues according to (c) as a deformed and compressed plug.
  • FIG. 8 a further improvement in the effect is brought about by elevations 27 on the pressing element 13 which are designed as cones and have holes not shown. They are attached to the side facing the material to be pressed and are pressed into it during the pressing process. This advantageously shortens the path for the water.
  • Fig. 9 shows the arrangement with such designed pressing elements 13 and 14 together with the upper (23) and lower (24) plate in section.
  • the pressing elements 13 ′′, 14 ′′ can be designed such that they can treat the material A ′ to be pressed particularly intensively in several individual steps. Therefore, the pressing section 6 is shown here as being divided into partial pressing sections 6 'and 6' '. After pressing in the partial pressing section 6 ', the material reaches the partial pressing section 6' 'through the pressing material, not shown, after the pressing elements have opened again. Then another strong compaction and drainage takes place. When the pressing elements are opened again, the plug which is still compacted can fall out or be pressed out by the following material. The paragraph 26 shown can advantageously enhance the effect, but is not necessary. Of course, other partial press sections, not shown, can also follow.
  • the openings in the pressing elements, not shown here can be chosen larger for better water drainage where the material is more compressed because the plug, which is then more compacted, has less tendency to press into the holes and thus block them.
  • Fig. 11 schematically represents another possibility, namely how the pressing elements 13 'and 14' on the housing 15 can be pivoted by joints 25 and moved by servomotors 19 '.
  • the open position is drawn thinner than the press position.
  • Fig. 12 is a sectional side view - somewhat exaggerated for clarification - the pivoting movement of the screw conveyor 7 together with the Drive unit 16 'shown.
  • the pivot point D for this rotary pendulum movement lies, viewed axially, in the area of the screw bearing.
  • the bearings 28 and 29 shown there can absorb both the axial forces and the radial forces at this point, but the possibility of the screw axis to carry out a rotary pendulum movement is retained.
  • the drive unit 16 ' is essentially carried by the described bearing, since it is connected to the drive-side end of the screw conveyor 7.
  • the torque resulting from the driving force is transmitted to the housing 15 of the press via the torque support 30.
  • the lever torques on the bearings 28 and 29 originating from the weight forces of the screw conveyor 7 and the drive unit 16 ' can essentially balance each other.
  • the discharge device contains a frame 31 which is fastened in hinges 32 to parts of the housing 15 of the dewatering press so that it can be opened and closed.
  • This frame 31 in turn carries joints 25 which serve to fasten the simplified pressing elements 13, 14 so that they can be moved relative to the frame 31. If the discharge device is folded down while the dewatering press is at a standstill, the end of the screw conveyor 7 is relatively easily accessible, while the plug A 'can remain in the pivoted discharge device. For example, after the maintenance work on the dewatering press has been carried out, the discharge device can be folded forward again and the operation of the dewatering screw can be started again. Since the plug A 'has returned to its old position, the optimal operating state of the dewatering press is reached relatively quickly.
