Definitions
- the invention relates to a rotor shear for comminuting, in particular, bulky waste with at least two cutting rotors which are mounted in parallel in a housing, in opposite directions and mesh with one another, each consisting of a plurality of cutting rotors which are lined up at a distance from one another, with against the circumferential surface of the opposite shaft or Spacers and rotor disks working against each other are provided.
- Such rotor shears are known and are mainly used for crushing waste such as bulky waste, household waste, old tires, bottles or containers made of metal, plastic and the like. Because of the different, often very resistant and tough materials contained in the bulky waste, such as bulky steel parts, steel inserts in old tires, etc., there are great problems with regard to the radial and axial forces to be absorbed and wear, which ultimately have an adverse effect on the shredding process impact and significantly impair the availability of rotor shears.
- the invention is based on the object of constructing a rotor shear of the type mentioned at the outset in such a way that the respectively changed machine elements lead to an effective comminution process, optimum wear behavior and a reduction in the bearing load.
- this task can be solved by three sibling variants each.
- at least one outer rotor disk of a cutting rotor be assigned a wear disk corresponding to its circumference and connected to the shaft in order to reduce wear, promote the size reduction process and reduce the bearing load by reducing axial forces.
- This inventive measure has the effect that
- the second inventive solution of the task which is subordinate to this variant, provides for at least one shaft to be assigned a support / scraper device in such a way that, with a functionally independent support part, the shaft or the spacer ring in a sector between bottom "dead center” and horizontal Line of symmetry and with a stripping part which is functionally independent of the support part in the region of the lower "dead center” of the shaft or the spacer ring.
- REPLACEMENT LEAF A reduction in wear due to the prevention of jamming of the comminuted material
- the support / stripping device according to the invention can be carried out according to claims 12 to 27.
- the surface of the front tooth flank of at least one cutting tooth consists of geometrically offset and / or angled partial surfaces, which lead to a gradual shredding and an optimal effect of the shredding edges and partial surfaces involved in the shredding process. It is due to this changed tooth geometry
- REPLACEMENT LEAF such as favorable wear behavior, lower bearing loads and an improved comminution process.
- the particularly high availability of rotor shears is thus achieved because it can be optimized with respect to the material mixture to be shredded or can be designed according to this.
- FIG. 4 versions of cutting teeth according to the invention in the forms as shown in a) to e).
- a rotor shear consists essentially of two parallel to each other in a housing 1, counter-driven, intermeshing cutting rotors 2, each of which are lined up at a distance on the shafts 3, with against
- the housing 1 has rear walls 1.1, end walls 1.2 and partition walls 1.3.
- the shafts 3 are mounted in the end walls 1.2.
- the on the meshing cutting rotors 2 by means of spacer rings 4 spaced rotor disks 5 are arranged so that the overhead cutting rotor 2 shown in Fig. 1 has a wear disc 7 on the left side, which connects to the outer rotor disc 5 and is positive or non-positive (Fig. 2) or connected to the shaft 3 by means of a thread, not shown.
- This wear disk 7 corresponds to the circumference of the outer rotor disk 5 and can advantageously be made slightly larger in diameter than the rotor disk 5.
- the wear plate 7 runs with or without play against an outer spacer ring 4.1 of the opposite shaft 3.
- the cutting rotor 2 formed with this shaft 3 has on its right side a further wear plate 7, which is arranged and designed in accordance with the first wear plate 7. Both wear disks run in corresponding bushings of the dividing walls 1.3 delimiting the comminution area. Designs are also possible, according to which the wear disks 7 are designed as a collar or flange-like part of the shaft 3.
- FIG. 1 The embodiment shown in FIG. 1 is also conceivable in such a way that only one shaft 3 is assigned two outer wear disks 7, each running against corresponding outer spacer rings 4.1 of the opposite shaft 3 with or without play.
- the idea of the invention can also be applied to the rotor shears which have several pairs of cutting rotors 2.
- the wear disk 7 does not abut directly against a rotor disk 5, but is separated from it by a spacer ring 4 or 4.1, the opposite rotor disk 5 then being practically sealed to the partition 1.3. It is essential that a couple
- REPLACEMENT LEAF a maximum of two wear disks are assigned by intermeshing cutting rotors 2, each abutting an outer rotor disk 5 in the direction of the end wall 1.2 and firmly connected to the shaft 3. This arrangement has shown that jamming of comminuted goods, as previously, between fixed wear elements and the cutting rotor 2 is avoided, and thus the wear on the housing is reduced significantly. The lower axial forces increase the service life of the bearings. Overall, the shredding process improves and the rotor shears alone get a higher availability.
- each embodiment is designed in such a way that the functions of support and stripping are decoupled, that is to say that each support / stripping device according to FIGS. 3a, b, c with a functionally independent support part 8.1, the spacer ring 4 in one sector 3.1 between the lower "dead center” and horizontal symmetry line and with a functionally independent stripping part 8.2 in the region of the lower "dead center” of the spacer ring 4.
- these agents contribute to reducing wear, ensure a longer service life of the bearings, since the shaft 3 is relieved, and lead the features according to the invention to a more effective comminution process, i.e. to further increase the availability of the rotor shear.
- the supporting / stripping device 8 according to FIGS. 3a, c can be designed as a structural unit, according to FIG. 3a the stripping 8.2 can be designed as a resilient component and according to Fig. 3b it can consist of separate components, such as the supporting part 8.1 and stripping part 8.2. As shown in FIG. 3c, there is an additional one to avoid material jamming during reversing operation
- REPLACEMENT LEAF Scraper part 8.3 is provided, which is expediently pivotable. All of the embodiments have in common that the cutting rotors 2 can be removed from the housing 1 without removing the support / stripping devices 8. Depending on the comminution material, different assignments are possible, namely as shown in claims 13 to 24 and 26 and 27.
- the surfaces of the front tooth flanks 6.1 of the cutting teeth are finally designed in such a way that geometrically offset and / or angled partial surfaces, in order to further increase and support the availability of the rotor shears 6.5 arise, which lead to a gradual shredding and an optimal effect of the shredding edges 6.2, 6.3 and partial surfaces 6.5 involved in the shredding process.
- the cutting teeth 6 can then be used with the proposed geometries, which are matched to the mixture of materials to be shredded.
- FIG. 2 analogously to FIG. 4b, e and generally transferable to FIGS.
- the crushing edges 6.2 being those between the front tooth flank 6.1 and the end faces 6.6 lying edges, which work against the shredding edges 6.2 of the cutting tooth 6 of the opposite rotor disk 5 and the shredding edge 6.3 are defined as the edge lying between the tooth head 6.4 and the front tooth flank 6.1, which works against the spacer ring.
- the angles 6.7 between the partial surfaces 6.5 of the front tooth flank 6.1 and the end faces 6.6 are designated, which in the case of the embodiments according to FIGS. 2, 4a, b, e are approximately or exactly 90 °, a slight drop below such as 89 °, can be advantageous under certain conditions.
- REPLACEMENT LEAF 2 4a-e do justice to the basic principle of the inventive concept and, according to claim 32, enable the use of different cutting teeth 6 which is matched to the respective comminution process.
- the basic functions of cutting teeth are combined and gradually to Effect brought, with reference to claims 30 and 31 of Fig. 4c, the refractive or the cutting function according to Fig. 4d is in the foreground. Due to the design of the cutting tooth 6 with the drawn-in front tooth flank 6.1 and the return to the tooth head 6.4 on the rear tooth flank (not shown), even after a possible breakage of the tooth due to the present cross-sectional conditions, an effective residual remains advantageously Cutting tooth.
- REPLACEMENT LEAF Increase the availability of rotor shears, such as coupling the wear disc 7 to an outer rotor disc 5, assigning support / stripping devices 8 to the cutting rotor 2 and geometrically offset and / or angled partial surfaces 6.5 of the front tooth flank 6.1 of the cutting teeth located on the rotor discs 5 6.
