Definitions

  • the invention relates to a comminution machine with a housing provided with a good inlet, in the end walls of which a rotor equipped with comminution tools is rotatably mounted with a horizontal axis, and with an interchangeable outlet grate arranged below the rotor and having axially parallel grate bars.
  • the US-PS 24 50 492 shows and describes a shredding machine of the above type.
  • the grinding grate essentially encloses the lower rotor half.
  • the grinding grid which has axially parallel grate bars, can be moved halfway horizontally out of the housing on rails.
  • the lateral, horizontal extension of the grate with respect to other subordinate units, such as feed and discharge devices, dedusting and viewing devices and their holding structures brings with it considerable problems.
  • this known grate construction it is not possible to adapt the grate to different types of feed.
  • This shredding machine is therefore also a complicated and expensive construction.
  • An essential, unfavorable factor is that only after several work steps - namely opening the housing, lifting the rotor and carrying out the associated safety measures - the grinding grate to be replaced is freely accessible .
  • Adaptation to different types of feed is also not possible with this type of construction.
  • the invention has for its object to provide a comminution machine of the type described above, which both allows a quick change of grate, as well as an individually adapted to the respective requirements Setting the machine to the different types of material to be shredded allowed without a basic disassembly of the shredding machine being necessary. Proceeding from this, the object is achieved in that at least one of the end walls of the housing in the region of the cross-sectional contour of the outlet grate has at least one opening in which the outlet grille is mounted and through which the outlet grate is completely or partially exchangeable in the axial direction. For the opening there is preferably a sickle or ring shape.
  • the replacement of the outlet grate is possible in a surprisingly simple manner at this point.
  • the corresponding grate can be installed and removed either as a whole or as a part or individual bars, the choice of grate structure determining the production or economic reasons becomes. If it is necessary to replace the outlet grate, the storage of the grate in the end walls of the housing has a particularly favorable effect; this means that direct access to the outlet grate is guaranteed, ie 5 in other words that the grate is immediately freely accessible without having to carry out complex dismantling or disassembly of other machine components beforehand.
  • each grate bar when dividing the outlet grate into individual interchangeable grate bars, can be attached to at least one of the ends, preferably, a tellstuf on the side where the replacement of the grate is made - have tes, projecting out of the housing end-piece which pulls the trigger is for limiting the axial mobility with the stepped face against the inner surface of the end wall of the housing.
  • the opening provided for the replacement of the outlet grate by at least one cover locked is ensured according to an advantageous development of the invention.
  • the exemplary embodiment according to the invention offers considerably greater security against the possible falling out of individual grate bars, in which the cover projects into the opening in the end wall of the housing to limit the axial displacement by means of an extension piece that grips the grate bars.
  • each exchangeable grate bar has an engagement groove at least one of the ends, in which engages in the opening protruding into the opening of the end wall located on the cover.
  • each exchangeable individual grate bar has at least two the grate bar arrangement has spacing cams which keep the individual grate bars at a distance from one another and which, due to their shape, both the respective different grate gap widths and the different gap shapes, ie determine the lay angle.
  • the varying, shape-like design of the distance cams offers space for additional manipulation options and has a direct influence or impact on the grate gap width, the gap shape or on the relevant impact angle.
  • the impact angle is below 90 o, and forms an acute angle, whereby it is reduced in dependence on the grate gap width accordingly.
  • This possibility of manipulation by means of the distance cams or by the inclination of the grate bars can, on the one hand, achieve better comminution and a resulting higher throughput rate for certain materials to be shredded, for example bark and wood, and on the other hand clogging of the outlet grate or the Rust bars can be largely prevented.
  • the interchangeable grate bars are secured against rotation in the circumferential direction by at least one axially extending, fixedly fixed stop bar against which the individual grate bars connected are supported.
  • the comminuting machine designated overall by 1, has a housing 2.
  • a comminuting rotor 3 rotates in the direction of rotation R, the axis 4 of which is mounted on both sides in bearings 7, 8 fastened to bearing blocks 5, 6.
  • the comminution rotor 3 consists of a plurality of rotor disks 9 lined up at a distance on the axis 4, between which comminution tools 10 are rotatably held on axles 11 which pass through the rotor disks 9 at a radial distance from the axis 4 parallel to the latter.
  • Axis 4 is connected to a drive (not shown) via a coupling. Due to the special arrangement of the chops shown in FIGS. 4 and 5 Removal tools are rust bars or an outlet grate 14 formed from them evenly coated by the crushing tools 10, which, in addition to uniform crushing, also reduces wear and reduces downtimes between the necessary rust changes resulting from wear.
  • a good inlet 12 and a good outlet 13 are provided in the housing 2.
  • the material inlet 12 is located on the upward-rotating side of the comminution rotor 3 above the rotor axis 4.
  • the material outlet 13 is covered by the outlet grate 14 and an end flap 15 which adjoins the grate 14 on the upward-rotating side of the rotor 3.
  • the end flap 15 serves to influence the possible additional piece size and to remove rust blockages and can alternatively be adjusted purely mechanically or hydraulically, in the exemplary embodiment shown in FIGS. 1 and 2, for example, by means of a ratchet pawl 16.
  • the various positions of the end flap 15 can thus be fixed accordingly.
  • the outlet grate 14, which consists of grate bars 17 which are mounted directly on the end wall (s), essentially encloses the lower rotor half. At least one of the end walls 18, 19 of the housing 2 has an opening 20 in the region of the cross-sectional contour of the outlet grate 14 shown in FIGS. 1 and 2 (see FIGS. 2, 4 and 5) in which the grate or the grate bars are mounted is or are and through which the outlet grille 14 is completely or partially exchangeable in the axial direction.
  • the opening 20 has a sickle or ring segment shape.
  • a web 22 anchored in the end walls 18, 19 of the housing can be arranged in the vertical plane I-I of the rotor axis 4. This ensures that when replacing a single grate bar 21, not all of the previous grate bars 21 need to be replaced.
  • the number of grate bars 21 to be removed is considerably reduced when replacement is required and can be further reduced if further webs are arranged.
  • the individual, interchangeable grate bars 21 can be on at least one of their ends; in particular on the side on which the grate bars are exchanged, be provided with a stepped extension 23 protruding from the housing 2, so that the stepped surface 24 to limit the axial mobility of each grate bar 21 against the inner surface 25 of the End wall 18, 19 of the housing 2 bears, as shown in Fig. 5, 6 and 6a.
  • the removal and installation of the individual interchangeable grate bars 21 can additionally be simplified in that a tool recess in the form of a groove 23a, for example an elongated hole, is provided in the extension 23 of each grate bar 21, which is expanded in the middle by a bore , as it shows the top view of FIG. 6a.
  • two support blocks or a support bar 26 are provided on the inner surface 25 of the end wall 18, 19 of the housing.
  • At least one cover can additionally secure the grate bars 21 27 are attached to the outer end wall 18, 19 of the housing 2, which, as shown in FIGS. 3 and 5, presses against the outwardly protruding, stepped extension piece 23 and thus holds the individual grate bars 21 in position.
  • three covers 27 are provided instead of one cover 27.
  • cover 27 it would also be conceivable for a different embodiment of the cover 27 than the cover 27, which smoothly closes with its contact surface with the opening or end wall 18, 19, for example a cover could also be used for the stepped grate bars, as described below is explained in more detail and is shown in Figures 4 and 7a to another embodiment.
  • FIGS. 4 and 7a and b Another embodiment of an exchangeable grate bar 21 is shown in FIGS. 4 and 7a and b.
  • This grate bar 28 which is smooth at the ends, can be secured against axial displacement by a simple cover 29 fastened to the outer surface of the end wall 18, 19 of the housing 2, as is shown, for example, in the exemplary embodiment according to FIG. 4.
  • the cover 29 does not necessarily have to be provided, as in the exemplary embodiment shown, with an extension piece 30 which extends over the grate bars and which projects into the then graduated opening 20 in the end wall 18, 19 of the housing, but rather the cover can be used with it Contact surface with the outer surface of the end wall 18, 19 smooth complete or align, as shown in Fig.
  • each exchangeable smooth grate bar can have an engagement groove 31 at at least one of its ends, into which the opening 20 of the End wall 18, 19 protruding projection 30 located on cover 29 engages.
  • an axially extending, fixedly fixed stop bar 32 which is attached and shown on the grate ends in FIG. against this stop bar 32, the grate bars 21, which are spaced apart from each other, are supported.
  • Each exchangeable grate bar 21 can be provided with at least two, depending on the machine size or the length of the grate bar 21, but also with a plurality of spacer cams 21a which determine the grate bar arrangement, as shown in FIGS. 8a and b.
  • spacer cams 21a which determine the grate bar arrangement, as shown in FIGS. 8a and b.
  • the individual interchangeable grate bars 21 are kept at a distance from one another by the spacer cams 21a.
  • the upper dimension - b - of the distance cam 21a is decisive for the distance between the individual grate bars.
  • any desired grate gap width - c - can be easily generated.
  • Different shapes of the spacer cams 21a also allow a wide variety of gap shapes and beats kel ⁇ , or ß are generated.
  • Fig. 8c shows a further embodiment in which rectangular extensions 23 are attached to the end faces of the grate bars 21 in such a way - either, as shown, welded or screwed - that they hold the grate bars 21 at the desired distance by mutual abutment.
  • a groove 23a which facilitates manipulation can be provided in each attachment piece (only one shown in the drawing).
  • the screw connection of the end pieces offers a very simple possibility of exchanging them for those of other dimensions, so that this not only gives a quick exchange but also an excellent possibility for changing the grate bar distances.
  • the opening cross-sections and shapes of the outlet grate can be manipulated to influence the size and / or density of the material to be shredded. Whether the material turns out to be more or less dense and smaller or larger depends on the grate gap width - c - and grate gap shape chosen or the distance between the individual grate bars or given by the upper dimension - b - of the distance cam 21a.
  • the dash-dotted embodiment of the spacer cam 21a shown in FIG. 8b, the free end face of which is set back relative to that of the respectively adjacent rod, offers the advantage that the spacer cams 21a are largely protected against wear caused by the impact on the outlet grate or the grate bars Well evoked.
