Definitions

  • the invention relates to a dewatering press for substances that can be dewatered by compression according to the preamble of claim 1.
  • Their mode of operation is described below using the example of wastes generated in waste paper processing, but is also applicable to other substances 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 particular advantage of the subject matter of the invention is that the screw conveyor, which is subjected to particularly intensive stress, is not rigidly guided, but can assume a freely adjustable position within a certain range, depending on the nature and quantity distribution of the material to be pressed out.
  • a simple design, good accessibility to the discharge (cleaning) of the press and favorable wear behavior, in particular for the screw and screen jacket, are combined.
  • Such advantages can also be achieved by axial strips or the like which are often attached to the inside of the screen be reinforced. Excessive stress on the machine parts is again reliably avoided due to the possibility of evasion.
  • a particularly good and homogeneous drainage can be achieved because a uniform pressure distribution in the area of the jacket provided with an opening is possible.
  • the screw conveyor 3 is driven by a drive unit 12 which, as indicated schematically, sets the shaft of the screw conveyor in rotation via a belt or the like. It can also be seen that the drive unit as a whole is mounted in such a way that it rotates the pivoting movement of the screw conveyor 3 can participate.
  • the illustration in Figure 1 also shows an example of how the storage at the drive end of the screw conveyor 3 can be accomplished.
  • the bearings 16 and 17 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 12 is essentially carried along by the described storage, since it is connected to the drive-side end of the screw conveyor 3.
  • the torque resulting from the driving force is transmitted to the housing 15 of the press via the torque support 13.
  • the lever torques on the bearings 16 and 17 originating from the weight forces of the screw conveyor 3 and the drive unit 12 can essentially balance each other.
  • FIG. 2 The same pressing device is shown in FIG. 2 as a view from above with a view of the housing 15 and the inlet opening 1.
  • Fig. 3 is a sectional side view - a little exaggerated for clarity - the pivoting movement of the screw conveyor 3 together with the drive unit 12 is shown.
  • the pivot point D for this rotary pendulum movement lies, viewed axially, in the area of the screw bearing.
  • FIG. 4 shows a schematic view of the subject matter of the invention, the viewing direction being chosen axially from the outside of the exit area of the press. You can see the screw conveyor 3 with the helix 3 'and the outer surface 3''.
  • the screen jacket 4 is attached to the machine frame 20 at the points 21 shown, while a large part of the screen jacket circumference by radial opposite bracket 18 is held, which in turn have a movement - albeit limited - at right angles to the screw axis relative to the machine frame 20. They are connected to one another by connecting elements 19.
  • the screen jacket 4 can be attached in such a way that it is only held on the end face and is otherwise movable on its long side relative to the machine frame 20 (FIG. 6).
  • the screen jacket 4 can advantageously also consist of two half cylinders which are pressed together by the brackets 18.
  • FIG. 4 also shows a number of strips 22 which are axially fastened to the inside of the screen and which serve to prevent the material to be conveyed from circulating and also to protect the screen surface from wear. They can run exactly axially or at an angle. Their effect is also favorable for the dewatering function of the machine, since the material can be processed between the helix 3 ', in particular its outer surfaces 3' ', and the strips 22 mentioned, as a result of the rotating pendulum movement of the screw conveyor 3.
  • FIG. 5 shows in the same direction of view as in FIG. 4, enlarged and very schematically, different positions of the rotating, variable-position screw conveyor 3, different positions of the same screw being illustrated by different broken lines.
  • the passage openings in the sieve jacket4 are not shown here.
  • FIG. 7 explains in a diagram the individual functions that can be fulfilled by a special form of the device according to the invention, which is described, for example, in claim 13.
  • a waste paper stock S is processed in the preparation 25, waste being produced, while the processed stock S ', which has been at least partially cleaned of waste, is carried on.
  • the waste arrives as the material A to be dewatered in a conveyor 26 with a conveyor and drainage section 6.
  • water W is removed from the waste.
  • the material A 'thus dewatered is then subjected to the pressing treatment 27 in the pressing section 7 and, with the release of further water W', is dewatered even more than the plug-shaped material A ''.
  • FIG. 8 shows a special pressing device, shown as a view from above with a view of the housing 15.
  • the substance A passes through an opening 1 into the press and is treated as already described. After passing through the conveying and dewatering section 6, it arrives in the area of the discharge 12.
  • the pressing elements 23 and 24 are used in the pressing section 6 which now follows. In the case shown here, they can be moved at right angles to the conveying direction of the screw conveyor in guides 28 and are periodically pressed against the material A 'by servomotors 29.
  • The, for example, hydraulically operated servomotor is supplied with a pressure medium via pipe socket 30. By pressing further water W 'gets into the drainage box 8.
  • other press force generating devices 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 12 which - as indicated schematically - sets the shaft of the screw conveyor in rotation via a belt or the like.
  • Fig. 9 schematically represents another possibility, namely how the pressing elements 23 'and 24' on the housing 15 can be pivoted by joints 33 and moved by servomotors 29 '. The open position is drawn thinner than the press position.
  • 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 33 ', which serve to fasten the simplified pressing elements 23'',24'', so that they can be moved relative to the frame 31.
