Definitions
- the invention relates to a shredding device for
- Shredding of all types of products consisting of at least one rotor, on the circumference of which hooks are attached, and at least one stator.
- Such machines are used to shred all types of products, especially in the context of the disposal, processing and recycling of waste and materials.
- the material fed into the comminution device is gripped by the hooks of at least one rotor, pulled downward in the material flow direction and, depending on the type of comminution device, torn, shredded, broken, cut and / or crushed depending on the type of comminution device.
- Shredding machines can be driven hydraulically and are provided with the known devices for automatically changing the direction of rotation for forward and backward running.
- a problem with such shredding devices is the wear of the hooks and the stator depending on the material to be shredded. As a result of the wear, the gaps between the shredding elements increase, which reduces the efficiency of the shredding as a result of wear. The replacement of worn elements is very expensive and time consuming.
- Shredding elements of the rotor U-shaped disk segments are put over as wear protection.
- DE 196 19 411 describes a mineral processing machine in which the comminution takes place by means of two toothed rollers, the teeth of which are at a radial distance are arranged from each other.
- the teeth of the two toothed rollers additionally push the final grain through a comb-like, flexibly mounted die and thus reduce the size.
- the matrix cuts, breaks and tears on three edges of the teeth.
- the distances between the teeth and the die have only a small amount of empty space, so that even small parts that are not necessarily to be shredded are detected in this machine and cause wear.
- the teeth of the toothed rollers, which are difficult to repair, are particularly subject to wear due to the first size reduction process and the subsequent pushing through the dies.
- the invention has for its object to provide a shredding device in which the wear on the shredding elements is both low and can be compensated for without removal and the associated downtimes.
- This task will include solved by the features of claim 1 for the first time in a surprising manner.
- Alternative or advantageous developments of the invention are described in the dependent claims.
- the invention is based on the basic idea that, on the one hand, a special arrangement of the hooks on the rotor and the comminution elements on the stator leads to little wear, and on the other hand, this compensates for the space between the hook of the rotor and the stator which is increased as a result of the wear can be that on the one hand the stator is displaced in the direction of the rotor axis and / or in the direction of the rotor axis and on the other hand the stator is rotated by a certain angle, so that a worn side of the stator is replaced by an unused side of the stator.
- Shredding elements is extended many times over. Through the adjustability of the position of the stator in relation to the rotor, throughput and grain size can also be regulated.
- Figure 1 shows a shredding device in cross section with two rotors and a stator.
- FIG. 2 shows the comminution device from FIG. 1 in
- Figure 3a shows an adjustable locking of the stator in a "lower” position.
- Figure 3b shows an adjustable locking of the stator in an "upper” position.
- FIG. 4 shows a hydraulic locking of the stator.
- FIG. 4a shows the hydraulic locking in a detailed view
- Figure 4b shows the hydraulic in a detailed view
- FIGS. 5a and 5b show a comminution device with four rotors and three stators.
- 6a and 6b show a comminution device with a rotor and laterally arranged stators.
- the material fed in is gripped by the hooks of at least one rotor, pulled downward in the direction of material flow and torn, shredded, broken, cut and / or crushed on a stator.
- the actual comminution takes place essentially through the interaction between the hook and
- the position of the stator towards the rotor axis offset - d "h is the distance decreases to the rotor axis -.. And / or around the stator be rotated to change the position, the -.
- the stator can also be displaced axially, ie in the direction of the rotor axis, after the fixing has been released.
- Shredding elements of the stator can be reduced by simply moving the stator. Furthermore, the adjustment of the stator position opens an additional one Possibility to regulate throughput and grain size.
- the adjustment mechanism for displacing the position of the stator can, for example, be designed mechanically by screwing with a manually operated hydraulic cylinder or with an automated - in particular hydraulic - system.
- the stator is arranged downstream of the rotor in the material flow direction of the material to be comminuted. Due to the special arrangement of the hooks on the rotor and the stator according to the invention, the actual comminution takes place essentially through the interaction between the hook and the stator, since the distances between the rotor axes and the
- Free spaces between the hooks are so large that there is little interaction between the hooks of the rotors.
- the stator can be attached, for example, below the rotor approximately parallel to the rotor shaft and attached to the cross members of the frame of the comminution device. If several rotor shafts are attached, the stator is placed between the rotor shafts, preferably offset downwards. If necessary, the stator can also be protected by wear plates.
- stator can also be arranged on the frame laterally to the rotor, optionally between two hooks, and / or lengthways, optionally parallel, to the rotor axis and perpendicular to the hooks.
- Stators such as these, which in particular fulfill the function of a scraper that prevent the comminuted material from escaping against the direction of introduction, can also be displaceable in their position. With These stators reduce the space between the frame and the rotors.
- At least one fixed comminution element composed of one or more parts is fastened on the stator.
- This element can be interchangeably mounted on the stator and, if necessary, protected with wear plates or welds.
- Stator is selected depending on the function and the arrangement of the hooks on the rotors as well as the desired shredding performance in terms of throughput and grain size.
- stator with the comminution elements in the spaces formed by the rotors and hooks allows even small-grained material to fall through, while large pieces of material cannot fall through and are therefore comminuted.
- throughput and grain size are regulated and, among other things, achieves the following effects: cleaning of the rotor and its hooks, - additional comminution of the material between the rotor and stator, and more even grain size distribution due to the improved sieving effect.
- the front edges of the hooks are mainly, in particular each have a single side edge and possibly a front edge on the front side of a hook, and the breaking edges of the stator are exposed to wear, whereas the difficult rear edges of the hooks are only slightly worn. '' Small parts that do not have to be shredded can fall through and cause no additional wear. Due to the larger free spaces, the machine is also cheaper and lighter, since material can be saved.
- the shredding elements on the stator are plate-shaped, and they can have a polygonal or disk-shaped cross section.
- the comminuting elements preferably have at least three side edges, one of which is oriented essentially transversely to the material flow direction of the material to be comminuted and cooperates with the hook.
- the comminution element has four side edges and an essentially orthogonal shape. Because of this construction, only one or a part of it
- Shredding element surrounding edges and sides involved in the shredding and affected by the material flow of the material to be shredded and the associated wear.
- the hydraulic system for locking or locking and / or moving the stator can also be used to protect against overload. If necessary, the hydraulic lock to avoid the stator when overloaded be set so that when a predetermined load is exceeded, the determination is released and the stator then either axially and / or shifts transversely to its axis. This is a significant simplification compared to the complex systems for overload protection known from the prior art, in which the stators are folded away in the event of overload, for example. If necessary, the hydraulic locking can take effect again as soon as the overload decreases.
- hooks are understood to mean the formations of comminution elements on rotors known from the prior art, which are suitable for grasping the material to be comminuted and comminuting it by at least one cutting, tearing or breaking effect. This term is also intended to include, for example, gear-shaped rotor disks.
- the hooks can be equipped with protective elements.
- Protective elements of this type are described, for example, in WO 00/44499.
- U-shaped rotor disc segments - possibly with extensions for shaft protection - can be placed over the hooks.
- the rotor shafts are arranged approximately parallel to one another.
- the opposing hooks on the rotors which are essentially parallel, are preferably arranged offset from one another, the distance between the rotor shafts being selected such that the effective ranges of the opposing hooks only overlap slightly and do not mesh with one another.
- the position of the rotor can also be displaced — optionally hydraulically. The same measures can be taken to adjust the rotor as to move the stator.
- FIG. 1 shows in cross section a shredding device according to the invention with a frame which is formed from cross members 8 and longitudinal members 9.
- Two rotors 1 designed as shafts are arranged essentially parallel to one another within the frame.
- Hooks 3 are attached to the rotors 1 as comminution elements. The distance between the rotors 1 is chosen so that the effective areas of the hooks 3 only interlock slightly.
- the material is introduced into the device above the rotors 1, is gripped by the hooks 3 and can, if necessary, be slightly pre-comminuted thereby.
- a bar-shaped stator 4 is arranged, on which the actual comminution process takes place.
- the stator 4 determined before rotation can be rotated about the stator axis 5. Are on the stator 4
- Comminution elements 6 with an orthogonal cross section attached The shredding elements 6 can be replaced individually if required.
- a side edge 10a of the comminution elements 6 is aligned transversely to the direction of flow of the material to be comminuted. Is the service life of the
- the stator 4 can be fixed and the stator can be rotated by 90 °, as a result of which the edge 10b, which is still unsealed in the circumferential direction and opposite to the direction of rotation, is transverse to the Material flow direction is brought. After the stator 4 has been re-established or locked, the comminution can be continued.
- lateral stators 7 are mounted on the two longitudinal beams 9 between the frame and the rotors 1 perpendicular to the rotor axis 2, and are optionally height-adjustable relative to the rotor axis 2.
- FIG 2 shows the shredding device from Figure 1 in supervision.
- the crushing elements 6 and the hooks 3 are arranged axially one behind the other on the rotors 1 and the stator 4, the hooks 3 of the rotors 1 arranged parallel to one another and the crushing elements 6 of the stator being offset from one another such that between each of two opposing hooks 3 the a comminution element 6 comes to rest in both mutually parallel rotors 1.
- the lateral distance between the comminution elements 6 and the hooks 3 or the gap between the hooks 3 and the comminution element 6 can be adjusted axially to the stator axis 5 by centering the stator 4.
