Definitions

  • the invention relates to a comminution device for comminuting different materials according to the preamble of claim 1.
  • Such shredding devices are known in various designs. They consist of a comminution roller rotatably mounted in a machine frame with at least one comminution tool arranged thereon and at least one shear bar which interacts with the comminution tool. Furthermore, the known comminution devices have at least one screening device for the comminuted material, the housing of which at least partially encompasses the comminution roller. The enclosure of the housing by the sieve device is necessary so that the shredded material can be fully collected.
  • the comminution roller generally has a multiplicity of comminution tools which interact with a corresponding number of counter cutting edges or with a one-piece counter cutting edge.
  • the shear bar can also be designed as a plate which has a number of recesses as shear bars corresponding to the number of blades.
  • the screening device covers the entire length of the shredding roller in order to be able to collect all of the shredded material completely.
  • the problem now is that if the sieve device becomes blocked or if the sieve device is changed with regard to the hole size, not only must the sieve device be dismantled, but also the shear bar.
  • the shear bar must then be readjusted to the roller. This takes time and is associated with a considerable amount of time, in particular when changing the cutting edges, when changing the roller or when changing the screening device, which extends the downtimes of such crushing devices and which thus leads to an increase in costs.
  • the US 4,385,732 relates to a comminution device which has two comminution rollers, the comminution tools of which each interact with a counter-comb.
  • the DE 299 10 770 U1 relates to a holder for teeth on a shredding machine, the teeth interacting with rotor teeth arranged on a rotor for shredding feed material.
  • the DE 299 10 772 U1 relates to a comminution machine with fixed, comb-like teeth that are laterally offset from rotor teeth arranged on a rotor.
  • the DE 297 18 512 U1 relates to a comminution device comprising a sieve and a counter knife.
  • the invention is based on the prior art described above and has set itself the task of proposing a comminution device, as described above, in which the assembly and disassembly of the screening device and the shear bar is made considerably simpler.
  • the invention proposes a comminution device according to claim 1.
  • the comminution device consists of at least one comminution roller rotatably mounted in a machine frame with at least one comminution tool arranged thereon and with at least one shear bar that interacts with the comminution tool and with at least one screening device for the comminuted material, the housing of which at least partially encompasses the comminution roller, the screening device and the shear bar form a common assembly, which is characterized in that the shear bar is plate-shaped and has recesses which correspond to the shape of the shredding tools of the shredding device.
  • the crushing tools run through the recesses during rotation of the roller during operation. Accordingly, the shape of the recesses is designed to correspond to the comminution tools.
  • the counter cutting edges can be folded onto the lower body. Furthermore, it is provided according to the invention that the counter cutting edges can be inserted approximately vertically into the lower body and then pivoted downwards, as a result of which they are already partially locked. Then it is attached using a screw connection.
  • a further development of the invention provides that the shear bar is arranged on the screening device in the installation direction in the upper region of the screening device.
  • this configuration according to the invention is characterized in that the shear bar is provided in exactly the opposite direction to the previously usual arrangement in the lower region of the screening device. Changing the direction of rotation of the roller causes then brush the cutting edges or the rollers over the screening device in order to press the already shredded material through the openings of the screening device, if necessary.
  • This arrangement has proven to be particularly positive for a change of the entire assembly. Compared to the solutions known in the prior art, it is also much easier to obtain and, in particular, to maintain. The serviceability of such an arrangement is also significantly improved.
  • the shear bar is formed from a multiplicity of individual shear bars which are individually attached to the screening device.
  • This variant is particularly preferred, since it is very easy to replace the shear bar elements, and in particular when only one shear bar is worn, it can be exchanged without any problems.
  • the exchange of the shearbars is also much easier overall due to this training. You don't necessarily need a hoist to do this, which can be the case with a shear bar made of one piece.
  • the individual counter cutting edges form a comb plate.
  • These individual shearbars are arranged side by side so that, as previously described, they also act as a plate for the shearbar.
  • the individual counter cutting edges can be attached to or on a lower body. This also serves the better service, due to a very simple interchangeability. Furthermore, worn counter blades can be removed relatively easily from the lower body and replaced with new ones.
  • the invention provides that a screw is provided as the fastening means, which is guided through a hole in the lower body. On the one hand, this provides a secure fastening option. On the other hand, the principle of interchangeability is also observed here. It is thus possible to easily replace the counter cutting edges by loosening the fastening means, removing the counter cutting edge from the lower body and replacing it with another, new counter cutting edge and then fixing it again.
  • a particularly clever variant of the invention proposes that the lower body is designed in such a way that it differentiates individual counter cutting edges Able to take shape. It is now also possible to replace the individual counter cutting edges when other shredding tasks are planned or when they are worn out. As in the overall concept according to the invention, this can of course occur when the sieving device and the shear bar have been removed from the basket and replaced by a further sieving device with shear bar. Then the machine can carry out its shredding tasks again and the repair or replacement of the shearbars can then be carried out in a normal service interval, without the machine coming to a standstill.
  • the invention proposes that the individual counter cutting edges are provided with wear plates. This also serves to adapt to a wide variety of shredding tasks. When crushing solid materials, counter-cutters with appropriate wear plates must be used, which can also be replaced quickly due to the higher wear.
  • the invention proposes that the screening device be designed to be removable from the housing.
  • the screening device also has openings which serve for the fractionation of the comminuted material and which are arranged facing the collecting side of the comminution device.
  • the screening device is preferably basket-shaped.
  • a favorable variant of the invention proposes that the assembly, consisting of shear bar and screening device, is arranged so that it can be pivoted away from the comminution roller or swiveled toward the comminution roller.
  • the possibility of pivoting further improves the service on the screening device and shear bar.
  • a further development of the invention also provides that the openings of the screening device can be changed and / or exchanged with regard to their opening manner or opening size.
  • a defined grain can be set for the shredded material. This can be achieved very well with a sieve device which is designed like a basket.
  • the size of the openings can be changed in different variants. For example, it is it is possible to provide inserts for the openings, which are then removed when larger grain sizes are required. For smaller grits, another insert or an insert with different opening sizes is used.
  • the openings are preferably square or rectangular. Of course, they can also be round or oval.
  • the invention is not restricted to a specific form here.
  • the sieve device is also formed from individual segments which form the basket for the sieve device designed in the manner of a basket.
  • individual segments of the screening device can only be replaced.
  • these segments are easier to handle for the service personnel in terms of weight, so that either no lifting device at all or lifting devices of lower weight classes are required.
  • the sieve device is honeycomb-shaped or has honeycomb-shaped openings. This honeycomb shape enables a favorable fractionation of the material to be shredded.
  • the screening device is formed by individually or clasp-shaped rods which are arranged at a distance from one another and form a basket of the screening device.
  • These rods or clasp-shaped, essentially U-shaped, components of the screening device which are open on one side form a completely new screening device, which form a new basket, so to speak, which is particularly inexpensively protected against blockages.
  • An additional use is given by the fact that the comb extensions are now round, so to speak, and form the screen basket or the screen device.
  • the screening device itself is flexible or is formed from flexible material.
  • This flexible shape is particularly suitable in the previously described rod-shaped design, since it is relatively easy to obtain the rods from spring steel or resilient material. It is generally more difficult to manufacture an entire basket from spring steel. Accordingly, the device according to the invention, as previously described, also offers significant manufacturing advantages.
  • an additional insert is provided as a screening device and the insert was obtained in particular from a flexible material which is insensitive to impurities and / or impacts. This also means that blockages are avoided and, in particular, damage does not occur as often as in the prior art.
  • the screening device is therefore characterized in that springs arranged individually next to one another are provided, the springs being in particular clasp-like and U-shaped.
  • the springs can be made of round steel, square steel, polygonal, oval or the like and in particular of a resilient material such as spring steel.
  • the springs are adapted to the rounding of the comminution roller. This means that the springs which form the basket are always arranged at the same distance from it, at least in the region in which they enclose the comminution roller.
  • the invention is also characterized in that a flexible basket, formed from the springs described above, is additionally provided above a conventionally arranged basket, as a result of which different sieve grains are realized by the then provided two layers of such a sieve basket. It can be used to achieve a different fractionation or to carry out another pre-sorting by including larger components again in the shredding process.
  • the invention is also characterized in that the springs can be fastened to a console, a lower body or the like. It is furthermore advantageous if the console is provided, in particular, pivotably in or on the comminution device.
  • the springs are fastened to the support, the console or the like by means of fastening screws and flanges arranged on the opposite side of the screws and a matching nut. It is advantageous if a base plate is provided on the flange, which serves both as a wear plate and / or as a base for securing the spring against rotation.
  • the spring is angled at an angle of 95 [deg.] And the radius of the bending of the spring is preferably 407 mm.
  • the outer radius on the U-shaped clip is 43 mm at the outer radius of curvature and 7 mm at the inner radius of curvature.
  • the screening device can be combined as a system component with different comminution rollers of different diameters in such a way that different comminution tasks can be carried out with one comminution device.
  • the shredding device Given the high purchase value of the shredding device, this of course also serves to increase the universality of this device in order to be able to carry out a wide variety of shredding tasks.
  • a further development of the invention provides that the screening device is arranged such that it can move relative to the machine frame.
  • the shear bar will not be moved.
  • the shearbar must be movably supported on the screening device to ensure this function.
  • the relative movability of the screening device relative to the machine frame serves to improve the product throughput through the openings of the screening device and also serves to avoid blockages.
  • the shredding roller have an electric drive.
  • the screening device has a hydraulic drive.
  • the shredding device each has a drive for the shredding roller and the sieving device.
  • the invention also proposes that the position of the comminution roller and the screening device in the device be oriented essentially horizontally.
  • the screening device is arranged in the comminution device in such a way that it encompasses the comminution roller in the lower region in the installation direction. This also serves to fractionate the shredded material. Appropriate transport means are then passed through the screening device, by means of which the comminuted material is then transported away from the area below the screening device.
  • the invention provides that the screening device comprises the crushing roller, seen in section, in about 45% to 60%. This configuration has proven to be advantageous, since firstly the filling process is not hindered and secondly the comminuted material can be comminuted and fractionated sufficiently.
  • the invention is also characterized in that the lower end of the screening device and the upper section form an angle of 40 ° to 60 °, based on the installation level of the device.
