Definitions

  • the invention relates to a rotor with fixed shredding tools for slow-running shredding machines, in particular for bulky waste material, in which protective caps, which at least partially act as cutting tools, are attached to a rotatable support body.
  • Such, preferably slow-speed shredding machines can, for example, be rotor shears which are used to shred metallic and non-metallic material or a mixture of these two types of material, e.g. Bulky waste, serve and in their fixed housing two counter-rotating disc rotors are arranged.
  • Both rotor bodies are composed of a large number of rotor disks which, in alternation with spacer rings, are firmly connected to the rotor shaft.
  • the periphery of each rotor disk forms shear edges with the side surfaces, which interact with the shear edges of adjacent rotor disks of the other rotor body.
  • the end faces of the rotor disks are provided with cutting teeth which, in operation, come close to the respective spacer ring of the opposite rotor body in order to counter the spacer ring tool to exert a cross-cutting effect on the material cut into strips by the rotor disks.
  • the cross cutting process takes place under the action of the toggle lever, so that the cutting force when a cutting tooth approaches the opposite spacer ring reaches a value that can theoretically be infinitely large.
  • the wear in particular on the cutting teeth and the end and outer surfaces of the disks, is relatively limited.
  • the wear especially on the cutting teeth, increases by leaps and bounds.
  • the rotor disks and spacer rings lined up on the rotor shafts must be manufactured with great accuracy if devices with, for example, ten rotor disks and spacer rings are to form an optimal cutting gap on a rotor shaft.
  • the worn parts In order to restore the functionality of the device, the worn parts must be replaced. To replace the worn and useless ones Parts of the entire rotor body must be removed and disassembled so that the rotor disks and / or spacer rings can be armored by cladding and then machined. Due to the high demands on the manufacturing tolerances and thus also the tolerances after the armoring and mechanical processing of the rotor disks, such work can only be carried out by the manufacturer of the machine. This also applies in the event that one or more rotor disks are damaged during operation. Even then, the entire device or the entire rotor body must be returned to the manufacturer and repaired there.
  • European published patent application 0 006 261 describes and describes rotor shears which, in order to avoid wear and tear, have segment-shaped protective caps on the end and side surfaces of the rotor disks which cover the rotor disks on these surfaces.
  • the protective caps have a U-shaped cross-section and are provided with cutting edges on the end faces, which thus represent crushing tools, especially cutting teeth.
  • Each protective cap is connected to one of the rotor disks forming the supporting body by means of detachable screws. Instead of the rotor disks, the outer surfaces of the protective caps are now subject to wear. In the case of worn protective caps and / or cutting edges, only the protective caps are removed and in this previously known device replaced by new ones. In this respect, this device is already more service-friendly than the one mentioned above, in which the complete rotor body has to be replaced.
  • the cutting teeth work against the peripheral surface of the opposite rotor shaft.
  • the material which is initially divided into strips between the rotor disks, is then transversely divided between the cutting teeth and the rotor shaft, which acts as an anvil. It can happen that particularly hard or tough material opposes the transverse subdivision, so that very high radial forces are transmitted and the locking screws with which the protective caps are attached to the rotor disks are accordingly extremely stressed. In the event of a greater state of wear, the securing screws also loosen by themselves and can no longer fulfill their holding purpose, so that the protective caps fall off the rotor disks, which can lead to considerable damage to the machine during operation.
  • the locking screws arranged in the wear zone area also wear out with increasing wear of the caps on their heads, so that the protective caps can no longer be removed with conventional screwing tools and have to be drilled out.
  • This effort is correspondingly large. Above all, drilling out the locking screws is almost impossible because no drill can be inserted into the narrow distance between the rotor disks. But even during normal dismantling of the protective caps, loosening the securing screws - several per protective cap segment - is complex and leads to considerable machine downtimes.
  • slow-running shredding machines In addition to rotor shears, in which two cutting rotors mesh with one another, slow-running shredding machines also include machines with only one rotor, which then counteracts a fixed, e.g. comb-like counter tool works. As with the rotor shears, the same problem occurs with this type of machine with regard to wear on the cutting edges of the shredding tools with the resulting maintenance problems.
  • roller crushers the crushing teeth of which work against each other and which wear out very quickly as a result.
  • the invention has for its object to provide another protective cap connection for support body, wherein "support body” within the scope of the invention generally means rotating bodies carrying rotating tools.
  • support body within the scope of the invention generally means rotating bodies carrying rotating tools.
  • the invention thus goes a completely different way than known protective cap proposals, in that a function and task-specific connection division takes place in order to optimally accommodate the connection parts in terms of position and thus not only to avoid or avoid wear areas, but also to enable more compact designs, which in turn are simpler Assemble with greater freedom from maintenance.
  • wear-free area is understood to mean an area that is essentially not acted upon by the material and / or an area that is not subject to the wear caused by the comminution.
  • the securing connection which is preferably also located in the wear-free area, takes over all radially directed forces in its securing effect during operation, e.g. the radial components of the cutting forces or even a positional protection of the protective caps on the support body, as will be explained in detail later.
  • the invention enables designs in which the power transmission, i. essentially the connection resulting from the cutting work assuming the position, type and shape of the connection can be designed in such a way that the protective caps can be placed radially on the support body or the rotor disks in a simple manner.
  • the measures according to the invention ensure that the connections that secure the protective caps on the support body and transmit the operating forces are in one area lie where they are protected from wear and tear, so that the elements transmitting the operating forces are retained without wear. These connections are therefore not exposed to immediate wear, because according to the invention they are located inside the protective caps or preferably in the wear-free area and neither with the cutting teeth of the intermeshing rotors or with the cutting teeth on the protective caps nor with the associated counter tool and with the crushing material come into contact.
  • projecting parts on the support bodies or rotor disks or on the protective caps engage in recessed receiving grooves of the protective caps or the support body.
  • the projecting parts are designed as driver strips which run in the mounting direction of the protective caps, which can preferably be mounted perpendicular to the support body or rotor axis.
  • At least one holding element is preferably arranged as a force-transmitting connection on the circumference of the support body or the rotor disk per protective cap.
  • This stop element is preferably in a further development of the invention a retaining tooth which has a front flank in the direction of rotation of the rotor, which cooperates with a flank lying inside the protective cap as a force transmission.
  • the support body consists of a tubular drum with end bearing journals and the drum has openings through which a rear attachment piece of the protective caps protrudes, and the pipe or drum shell is provided with bores distributed in the axial direction over the circumference, aligned with the holes in the end pieces of the protective caps for pushing through the axle rods, an even more compact design is created, which further simplifies the assembly and further increases the freedom from maintenance, because the advantage of the tubular drum, that is to say one-piece support body design according to the invention is particularly in it see that there is no need for spacers that require additional caps.
  • This version which enables both a solid material and tubular drum, has the further advantage that both material and production are less expensive than with conventional rotors; namely, the elaborate machining of rotor shafts and rotor disks is partly eliminated. It is possible to manufacture the rotor as a cast part or the rotor jacket from a commercially available tube.
  • the design of the rotor as a cylindrical hollow body according to the invention also opens up the advantageous possibility of simplified storage, for example by a bearing journal on the respective end disks saving the expensive, continuous shaft of conventional rotors; the same applies to the rotor made of solid material.
  • drum equipped in this way is given the contour of a rotor, such as that used for rotor shears.
  • the drum can also have "structures" which serve to hold the protective caps.
  • a particularly secure fit and inexpensive power transmission can be achieved in an advantageous embodiment in that the inwardly projecting extension piece of the protective caps is graduated and its gradations interact with counter-stages of the supporting body.
  • the support body generally designated 1 in FIG. 1 is a rotor in this exemplary embodiment, which is mounted with its rotor shaft 2 in a housing of a comminution machine.
  • the housing is not shown in Fig. 1; only the drive 3 for the shaft 2 is visible.
  • a plurality of, for example circular rotor disks 4 and spacer rings 5 are alternately on the rotor shaft 2 fixed non-rotatably by a key 6.
  • the rotor disks 4 are covered with protective caps 7 which can be mounted transversely to the axial direction of the rotor.
  • the protective caps 7 which are U-shaped in cross section in the exemplary embodiment shown are provided with cutting edges 8 which mesh with an oppositely arranged counter tool 9.
  • the protective caps 7 are connected outside of the wear zone by non-positive and positive engagement with the supporting body 1, namely that projecting parts 10 on the supporting bodies, for example the disks 4 of the rotor or in the illustrated embodiment on the protective caps 7, engage in recessed receiving grooves 11 of the protective caps or support body.
  • the projecting parts are designed as driver strips 12 which run in the mounting direction Z of the protective caps 7 (see FIGS. 2 and 3).
  • These driver strips 12 can be arranged on the rotor disks 4, see for example FIG. 10, and engage in correspondingly recessed receiving grooves 13 in the protective caps.
  • the driver bars 14 can also be located on the protective caps 7 and the recessed receiving grooves 15, in which the driver bars 14 engage, can be arranged on the rotor disks 4.
  • the function of the driver strips can also take over a feather key 17 which, as shown in FIG. 9, is inserted into the receiving grooves between the protective cap and the rotor disk.
  • a radially projecting pin 19a is arranged in the interior 18 of the protective cap 19 and engages in openings 21 provided on the circumference 20 of the rotor disk 4.
  • the pin 19a is preferably formed in one piece with the protective cap 19.
  • a hollow body is also conceivable as a support body, the peripheral wall of which has continuous recesses for the cap pins. All of the exemplary embodiments explained above make it possible in an excellent manner to slide on or attach the protective caps perpendicular to the support body or rotor axis.
  • the protective caps can either be segment-shaped (six in the case of FIG. 2) or, as shown in FIGS. 3 and 6, consist of two half-shells 22a and 22b, each with a circumference of 180 ° .
  • the protective caps are radially secured according to the invention either by an axle rod 23 or alternatively also by a weld seam 86, in that the adjacent protective caps 7 and spacer rings 5 are at least partially welded to one another. If the protective caps need to be replaced, the axle rods 23 are removed or the weld seams 86 are separated.
  • Fig. 4 shows a corresponding application of the construction according to the invention. This is a so-called rotor shear 24 with two cutting rotors 26 which are mounted parallel to one another in a housing 25, are driven in opposite directions and mesh with one another, of which a section of a version of a rotor constructed from disks and spacer rings 5 and 27 in between is shown in FIGS.
  • the spacer rings 27 have recesses 28 of a depth which corresponds to the thickness C of the legs 29 of the protective caps 30.
  • the legs 29 of the protective caps protrude into the recesses 28 of the spacer rings 27 in the assembled state.
  • the legs 29 of the protective caps which are U-shaped in the exemplary embodiment, reach as far as the rotor shaft 2 and have shoulders 31 in the form of annular cylinders 31 on both sides in the region of the rotor shaft.

  • the spacer rings overlap the shoulders 31 of the legs 29 of the protective caps by means of the widenings 36 which are provided on the outer circumference and have a T-shaped cross section, which are caused by the recess 28.
  • FIGS. 12 to 14 show, in these exemplary embodiments the protective caps at the end of their U-shaped legs have additional or integrally formed lateral legs 29 in a flange-like configuration, which otherwise do not necessarily have to be present on the protective caps; rather, this cross-sectional shape, which can be seen in FIGS. 12 to 14, is a favorable realization of the second connection mentioned in the main claim, which ensures the securing of the connection and lies in a wear-free area.
  • This cross-sectional shape of the protective caps then enables the advantageous design of the securing bracket by means of spacer rings which are essentially T-shaped in cross section.
  • FIGS. 12 and 14 show a spacer ring 27 which is divided transversely to the rotor axis into three disks 37a, b and c, of which the two outer 37a and 37c are L-shaped in cross-section and at least the middle disk 37b consists of two half-shells, as shown in Figs. 7 and 8, is formed.
