Definitions

  • the invention relates to a device for shredding waste, according to the preamble of claim 1.
  • a device for shredding waste is disclosed in the document GB-A-2 031 754 described below.
  • the scrapers stand there from the vertical side wall of the housing and thereby fill the between the comminution rollers and a large part of the existing space on the side wall of the housing. This also prevents shredded material adhering to the shredding discs from being conveyed back upwards.
  • this is particularly disadvantageous in the case of non-brittle or only slightly brittle waste, since a storage space is formed in the wall area below the rollers, which is filled with partially shredded material and, after a relatively short operating time, leads to high loads and ultimately to the plant being blocked. This also has a detrimental effect on the fangs and the drive.
  • a file shredding machine which also has intermeshing shredding rollers, a ring being loosely arranged on the drive shaft in each space between two shredding disks, the inside diameter of which is larger than the diameter of the drive shaft and the outside diameter of which is smaller than that The diameter of the shredding roller is.
  • the material drawn in between the shredding disks constantly urges each ring to the drive shaft in a horizontal or slightly inclined direction, as a result of which the diametrically opposite area of the ring partially emerges from the space between the disks. Any material that remains between the panes is thereby discharged to the outside.
  • This document shredder is particularly suitable for shredding waste paper and similar materials that are cut into narrow, long strips. Their use for waste material of any kind, especially for bulky waste such as boxes, packaging boxes, waste with a higher moisture content, e.g. Pieces of bark etc. are hardly possible.
  • the invention has now set itself the task of creating a crushing device with repelling elements that crushes any, especially combustible waste material, the clogging of the spaces is prevented as possible, so that it is less susceptible to interference.
  • the comminuted waste material should also be suitable for briquetting in a screw press.
  • the cutting edge is preferably formed on a counter knife mounted on the deflector.
  • the deflecting elements can absorb extreme loads and represent massive counter knives which are comparable to the knife bar of the above-mentioned US-A-3 578 252 and AT-B-320 405.
  • the cause of the malfunction is usually that the material is only partly shredded or not shredded by the rollers
  • the waste before and after is removed in the device according to the invention Indirectly shredded when entering the work area, ie only material with a size is processed between the shredding disks, which can in any case come loose from the device.
  • the susceptibility to malfunction can be reduced even further if the cutting edge of each of the shredding disks assigned to the one shredding roller lies within the cylindrical envelope surface of the other shredding roller, so that the fangs of the shredding disks in the upper area as feed tools to the central shredding area between the two shredding rollers and the shredder if the end face of the deflecting element facing the comminution disk has a section that starts from the cutting edge and is concavely curved.
  • the latter limits the receiving volume between two teeth of a rice milling disk and the Abweiselemen t, so that this assists to define the size of the comminuted particles.
  • a combination of two different types of comminution is achieved by shearing off a portion of the waste piece to be processed between each fang of a comminution disc and the corresponding deflecting element, and then immediately or simultaneously by the interaction of the fangs of the intermeshing comminution discs further dismemberment takes place.
  • Relatively bulky waste material which is placed in the mostly funnel-shaped filling opening, can or the like with feed rollers. be brought into the attack area of the shredding rollers so that bridging is prevented as far as possible above the shredding rollers.
  • the deflecting element surrounds the drive shaft passing through the intermediate space and preferably consists of two parts placed against one another in the common axial plane of the two drive shafts, the lower part of which rests on the central carrier.
  • the end face of the deflecting element on the inlet opening is convex in the section extending over the bridge area, whereupon a section preferably rising between the bridge area and the side wall continues in order to largely prevent a dead space there.
  • the shredding device is therefore particularly suitable for combination with a screw press, in that the outlet shaft forms the filler neck of a screw press, the press screw of which is arranged below the two drive shafts of the shredding rollers parallel to the latter, the end face of each deflecting element facing the shredding disk serving as a guide surface for the press screw represents shredded material to be introduced.
  • the discharge quantity can be greater than the screw capacity.
  • this can be metered in a simple manner if a cutting edge is formed on the side of each slide facing the central web. It has no effect on the function of the comminution device if a short-term excess that possibly does not pass the slide is again conveyed upward by the fangs, since this consists only of material that has already been comminuted to the correct extent.
  • the space accessible from below between two axially successive shredding disks, in which a blockage could primarily be caused by material accumulations is filled by the deflection elements.
  • a further embodiment of the device according to the invention as a filling funnel of a screw press provides that the central web is U-shaped in cross section and forms the section of the screw tube which has the inlet opening.
  • This version is characterized by a particularly low overall height, since the shredded material leaving the work area falls directly into the press screw or is even pressed into it.
  • FIG. 1 shows a vertical section through the working space of a comminution device according to the invention along the line II of FIG. 2
  • FIG. 2 shows a horizontal section along the line 11-11 in FIG. 1
  • FIG. 3 shows a vertical section along the line 111- 111 in Fig. 4 by a second embodiment as a hopper of a screw press
  • Fig. 4 is a section along the line IV-IV of Fig. 3
  • Fig. 5 is a vertical section through a third embodiment
  • Fig. 6 is an enlarged bottom view of third execution.
  • the shredding device which consists of a housing 1 with an upper hopper 2 and a lower one Exit shaft 3 exists, contains in the part enclosed by the side walls 17 two counter-rotating crushing rollers which are arranged on the two drive shafts 4, 5.
  • the two comminution rollers each consist of comminuting disks 6, 7 which are spaced apart from one another and which mesh with one another, so that an intermediate space 8 is provided between two comminuting disks 6 and 7 axially successive on a drive shaft 4 and 5, respectively.
  • the shredding disks 6, 7 are equipped on their circumference with fangs 20, which are fastened, for example, in contact with one another in the circumferential direction on a carrier.
  • each deflecting element 9 is arranged in alignment, which is attached to the side wall 17, which surrounds the drive shaft 4 or 5 passing through the clearance 8, projects above the shredding roller downwards and on the underside an axially parallel center support 21 rests.
  • the end face 10 of each deflector element 9 facing the corresponding comminution disk 6, 7 is circularly concave in an upper section 30 and approximated to the cylindrical envelope surface of the comminution roller.
  • each tear tooth 20 and the upper edge 18 of the end face 10 thereby continuously form effective shearing or cutting elements, which separate two pieces of low height from a piece of waste to be inserted vertically between the two shredding rollers in the height direction of the hopper.
  • the height of these parts corresponds approximately to the peripheral distance of a tear tooth 20 compared to the previous one of the same shredding disk. It is also determined by the number of fangs 20 per disc and the staggered arrangement of the discs on the two drive shafts 4, 5, so that the height of the parts is rather less.
  • the cutting edge 18 of the end face 10 is primarily formed on a counter knife 19 mounted on the deflector element 9.
  • the size reduction stage which also exists in known devices and which divides the material in the axis-parallel direction by the overlapping of the rotating size reduction rollers.
  • the two essentially simultaneous crushing stages therefore only allow material particles below a size causing a build-up of dust or complete blocking to pass into the working space 29 between the two crushing rollers or between a crushing disc 6, 7 and the associated deflecting element 9, which on the underside without problems can exit freely.
  • Each deflector element 9 could, for example, be of U-like design in its basic form, one side leg being used for attachment to the side wall, the other side leg having the concave end face 10 and resting on the central support 21.
  • the embodiment shown in FIG. 1, whose compact design can absorb particularly large forces, provides a deflecting element 9 which surrounds the drive shaft 4, 5. It preferably consists of two parts 11, 12 which are screwed together, for example.
  • the upper region of each deflecting element 9, which spans the drive shafts 4, 5, is convexly curved in the first section 15, which extends from the cutting edge 18, to which an obliquely rising flat or concave section adjoins the side wall 17.
  • the distance between the convex end face section 15 and the axis of the drive shaft 4 or 5 is less than the radius of the comminution disk 6, 7, so that the effective areas of the fangs 20 protrude radially.
  • Material slipping on the wall of the filling funnel 2 slides along the inclined edge sections up to their transition into the convex sections 15, where it is gripped by the emerging fangs 20 and conveyed towards the cutting edge 18 on the counter knives 19.
  • the lower end face facing the outlet shaft 3 is flat.
  • a horizontally adjustable slide 25 is provided per comminution roller, through which the partial opening 37 of the outlet shaft 3 created by the central carrier 21 can be changed, and which is provided with a cutting edge 26. The slide also enables the material particles to be shredded.
  • each deflecting element 9 which faces the shredding disk 6, 7, and which ends in a tapering end 22, forms a guide surface 31 in the lower part 12 up to the central support 21 for the shredded material toward the partial opening 37, so that the one for the central support the deflecting elements 9 favorable central supports 21 do not impair the exit.
  • a recess 23 is provided in each deflector element 9 inserted in an intermediate space 8 of the second comminution roller, so that continuous free spaces are created in this area on both sides of the central carrier 21.
  • the shape of the recess 23 can be chosen arbitrarily. It enables a crushed material that has entered the space 8 to exit laterally.
  • a spacer ring 27 can be arranged, on the outer surface of which slanting grooves 28 are formed. These feed material that has entered there back into the gap between the shredding disk 4, 5 and each deflector element 9.
  • the spacer ring 27 can also be formed by a roller bearing, so that a multiple bearing of each drive shaft 4, 5 is achieved.
  • the embodiment according to FIGS. 3 and 4 shows a comminution device as a filling funnel of a screw press.
  • the shredder 1 and 2 consists of a housing 1 with a filling opening 2, in which feed devices can optionally be provided, a central part receiving the comminution roller and an outlet shaft 3, the opening width of which is small and the inlet opening into the Press screw 33 corresponds to the screw press.
  • the two shredding rollers in turn each consist of a plurality of shredding disks 6, 7, which are arranged in a rotationally fixed manner with axial gaps 8 on a drive shaft 4, 5 and which are equipped with tear teeth 20 on the circumference.
  • a deflector element 9 which is approximated to a shredding disk 7, the other shredding roller, is arranged in the intermediate space 8, which protrudes from the outlet shaft 3 through the working space 29 between the two drive shafts 4, 5 and into an inlet opening Cutting edge 18 runs out, which lies within the circumference of the shredding roller.
  • a guide surface 31 for the comminuted material also closes here.
  • the deflecting elements 9 are approximately L-shaped and extend below the drive shafts 4, 5 to the side wall 17, whereby they also rest on the central support 21.
  • the central support 21 is formed by a part 34 of the screw tube 35 with a U-shaped cross section, in which the press screw 33 runs.
  • the guide surfaces 31 of the deflecting elements 9 are aligned on both sides with the inner surface of the U-shaped part 34, so that the comminuted material falls or is pressed directly into the open press screw 33.
  • the size of the working space 29 is chosen so that for all materials to be processed at least a sufficient, but preferably an excess amount of the comminuted material is pressed into the press screw 33, so that a slight pre-compression can already be achieved.
  • the shredding device is closed by base plates 39 on which the deflecting elements 9 also rest. It is therefore sufficient even in the case of heavy loads to have an L shape, so that an upper part 11 according to FIG. 1 can be omitted.
  • Fig. 4 shows the thickness of each deflector 9 in the area of the working space 29 less than the width of each space 8 between the shredding discs 6, 7, so that in the lower part preferably by means of additional plates or the like.
  • FIG. 5 and 6 show a further embodiment in which the comminution device is part of a screw press.
  • the two drive shafts 4, 5 of the shredding device are in turn mounted parallel to the pressing disk 33, each of which is equipped with the intermeshing shredding disks 6, 7 provided with tear teeth 20.
  • a grid, a bar grate or the like extends below the comminution roller. through the outlet shaft 3, which divides its partial openings 37.
  • the deflecting elements 9 again alternately extend through the working space 29 between the two drive shafts 4, 5, again from the central support 21, which (FIG. 6) forms a central rod of a bar grate 39, and they contact the tear teeth 20 of the shredding disks on the inlet opening side 6, 7 form approximate cutting edges 18.
  • each end face of the deflecting elements 9 again represents a guide surface 31 towards the partial openings 37.
  • Sliders 25 are provided below the grid or the rod grate, which enable the correct metering of the amount of the crushed material to be fed to the press disk 33.
  • the openings of the grid or the spacing of the grate bars 38 are at least as large as the size of the material pieces comminuted between the tear teeth 20 and the cutting edges 18.
  • the total passage area of the grate or bar grate is reduced by moving the slide 25. This can be done manually, but is preferably coupled to the screw press as a function of a function thereof.
  • FIG. 6 shows the slide 25 in detail from below, that is to say from the side of the press screw 33.
  • the slides 25 are formed by sheets which, in the closed state, also engage under the central support 21 which carries the deflecting elements 9 and have a toothing along their contact edges, for example the teeth 36 shown, which, in the closed state, completely close the outlet shaft 3 in an interlocking manner.
  • the openings 37 are gradually released from the center, FIG. 6 showing a central position.
  • the slider 25 could also be moved in a different way than shown, parallel to the grate bars 38.
  • the comminuted material is taken up again by the comminution rollers with a correspondingly reduced passage cross section or is circulated until the total passage cross section of the outlet shaft 3 is increased again, so that essentially one the absorption capacity of the press screw 33 in a simple manner is achieved. Any further comminution that may take place during this is of no importance.
