Definitions

  • the invention relates to a processing and crushing device with a rotatably driven and one-sided plate, the axis of which includes an angle to the vertical, with inlet and outlet openings for the material to be treated and with at least one eccentrically arranged and one-sided, high-speed rotor with several in the direction of it Axis of rotation spaced apart from each other.
  • a preparation and comminution device which can process materials of various compositions continuously and discontinuously in large quantities. This is primarily about shredding, mixing and sorting or sieving, activities that have to be carried out one after the other or simultaneously.
  • a comminution device is already known from German patent application DE-A-25 03 621, in which the high-speed rotor is provided with at least one toothed disc, the plane of which extends transversely to the rotor shaft and partly into the supercritical speed at the Immersed well held container wall.
  • This known shredding device allows a very versatile use, e.g. processing waste even delivered in garbage bags, cardboard boxes and bundled materials.
  • the known device is based on the principle that the materials to be processed, in particular for fine comminution, are held on the inner wall by the rotating container driven at supercritical speed and are comminuted by a toothed disk.
  • the critical speed is understood to be the number of revolutions per minute for the drive of the plate at which the centrifugal force is greater than the weight of the goods in question, so that the goods are pressed against the inner wall of the plate.
  • the machine is constructed in accordance with FR-A-593 871, in which a concurrent cover of the plate is mandatory for the functional sequence.
  • this cover which is designed as a storage edge, the cross-section available for loading and emptying is considerably reduced and is critical for bulky materials. Due to the storage edge, heavy components of the material to be treated, e.g. Metals, not discharged, but constantly fill the machine up to damage or overload. On the other hand, due to the arrangement of the plate and rotor, the storage wall is necessary, because otherwise the material to be treated does not remain in the plate.
  • the small inlet cross-section for loading the known machine only makes sense for very large plates.
  • a disadvantage of the known device is the mutual interference of the drivers in the plate and the splitting tools on the rotor, which are damaged or destroyed in the presence of material that cannot be shredded, for example metal pieces.
  • the known machine can not Shear and impact forces are developed simultaneously.
  • the wedge effect between the rotor and the plate wall is particularly disadvantageous, because if larger pieces of the material to be treated get between the plate wall and the rotor, in particular if their directions of rotation are the same, not only do energy peaks arise, but also a considerable bearing load, which under certain circumstances can lead to the rotor shaft breaking .
  • the screening drum known from DE-A-25 13 853 is so sensitive to metal and other hard materials that the processing and preparation of hard materials is not possible.
  • the beaters and ribs on the plate wall work together in a narrow gap so that metal parts cannot be processed.
  • the material to be treated is fed to the shredding tools with a disadvantage in the axial direction, and the shredding is not carried out on the tool side but in the radial brushing area.
  • the invention is therefore based on the object to provide a preparation and comminution device of the type mentioned which, with the avoidance of load peaks and without additional machines with simple tools, allows the processing, preparation, mixing and comminution of materials which are voluminous, bulky, coarse and can be hard, e.g. Garbage, possibly even up to a fine-fiber or flour-like disintegration of the particles; shear and impact forces are to be developed at the same time and the shear forces are to be applied in such a way that in the presence of material which cannot be comminuted, e.g. Pieces of metal, the tools are neither damaged nor destroyed.
  • the arrangement of the inlet device at the top brings the material to be treated safely and uniformly to the processing tools, so that a reliable grasping is always guaranteed.
  • the incoming material to be treated also generates the necessary contact pressure against the comminution tool in order to ensure that the shear forces of the rotor or rotors have a thorough effect.
  • the device according to the invention is surprisingly insensitive to the loading with different materials in one operation in a colorful sequence, for example with filled sacks, then pressed bales, empty boxes and liquid and plastic components etc.
  • a stationary cover prevents dust from escaping and air pollution, protects the environment from possibly ejected parts from the processing space of the device and allows the essentially horizontal arrangement of the plate rotation axis preferred according to the invention in some embodiments. This ensures good circulation of the material to be treated and ensures that all material parts fall down one after the other.
  • the inlet opening in the upper part of the stationary cover is large so that bulky materials, e.g. Garbage bags that can be checked in.
  • the overall structure of the device according to the invention is particularly simplified in that, according to the invention, the outlet opening is arranged in the lower region of the stationary cover; in other words, at the lowest point of the material to be treated.
  • the rotor in the device according to the invention has a large effective range both in the circumferential direction of the rotating plate due to the circulating material to be treated and in the direction of the plate depth in that it has several splitting tools in the direction of its axis of rotation.
  • This can preferably be cutting or striking tools, e.g. act radially arranged rods, teeth, baffle plates or other, possibly also armored striking tools, which stress the material to be treated with impact and tearing.
  • a preferred embodiment of the invention is characterized in that the outlet opening is designed as a discharge flap which is pivotally attached to the cover and is biased in the closing direction and is inclined in the direction of flow of the material.
  • the emptying of the device according to the invention can be regulated very finely and can be provided with the described devices and features without too much effort. Processes the shredder e.g. Household waste and similar substances, then it is important that the textile scraps, foils, etc. present in the regrind do not stick to the corners and gaps next to and at the outlet opening and lead to blockages there.
  • the outlet opening constructed according to the above features ensures trouble-free operation.
  • the inclined position of the discharge flap allows the material flow to be guided from the cover into the interior of the plate, so that the dangerous strand-like materials do not get stuck and can lead to blockages.
  • the discharge flap preferably does not reach all the way to the upper edge of the rotating plate, so that sufficiently comminuted ground material can, if desired, be discharged continuously.
  • the pre-tensioning of the discharge flap in the closing direction allows the setting of the pressure with which the flap acts against the reflowing regrind.
  • the flow properties of the material to be treated are further advantageously influenced by the fact that, according to the invention, deflectors and / or steering fins are provided in the region of the discharge flap. Due to the circulation of the material to be treated in the device according to the invention, a certain sorting takes place automatically, in which the finer material comes to rest in the radially outer part of the plate or in the region of the ground material layer and the coarser material in the upper region of the ground material layer or rises against the rotor in the radially inner region. Due to this sorting effect, mainly fine material emerges from the lower area of the discharge flap.
  • deflectors and / or steering fins which are, of course, on the inside in the area of the discharge flap, and the steering fins, which are preferably attached directly to the flap, help to deflect coarse material that is not yet to be discharged upwards, and a new one Feed processing.
  • the rotating parts are arranged with respect to one another in such a way that the tools do not interact with one another and the smaller parts can fall through between them and reach the lower part of the plate.
  • the outer circumference of the splitting tools of the rotor is provided at a considerable distance from the inner wall of the plate.
  • This embodiment of the device according to the invention avoids the disadvantageous clamping effects described above in connection with the prior art, so that damage is less to be feared, but the preparation is nevertheless carried out in a surprisingly complete manner.
  • the distance mentioned is particularly advantageous in the case of two built-in rotors in such a way that such a large material flow rises between the container wall and the first rotor so that the second rotor can be acted upon with sufficient force.
  • the invention is advantageously designed in that the axis of rotation of the rotor is arranged in the vicinity of the horizontal bisector of the bottom of the plate.
  • the splitting tools are then free, in particular when the plate rotation axis is oriented essentially horizontally, when the material to be treated is at rest, but mainly in the lower half or the lower third of the plate.
  • the wall of the plate has the shape of a truncated cone, the larger diameter of which lies on the side opposite the floor.
  • a large entry device or a large cover is obtained even with a relatively small plate, which allows the attachment of a large-sized inlet device.
  • bulky goods can also be processed.
  • the bottom of the plate can advantageously be relatively flat, i.e. in the direction of the horizontal, and thus increase the dwell time of the material to be treated.
  • the discharge conditions also improve due to the frustoconical plate.
  • the cone-shaped plate wall can be provided for certain tasks.
  • Such an embodiment is advantageously characterized according to the invention in that the jacket circumscribing the splitting tools of the rotor is a truncated cone. While in the case of normal, approximately cylindrical rotors, the axis of rotation in the case of the frustoconical plate must be arranged at an angle to the axis of rotation of the plate so that they largely cover the work surface on which the material to be treated lies, the last-mentioned feature of the rotor allows that its Axis can be arranged parallel to the axis of rotation of the plate.
  • the diameters of the individual, disc-shaped or designed splitting tools on the rotor are thus graduated so that the tools are at the same distance from the entire inner wall of the plate.
  • drivers are distributed on the inner wall of the plate. This measure, which is impossible with a plate rotating at a supercritical speed, allows the material to be safely brought up to the desired apex, from which the material falls and flows directly into the rotor like a waterfall.
  • the effect of these drivers is particularly intense if, according to the invention, they are arranged offset in height from one another.
  • the drivers are cam-shaped or tooth-shaped without an acute angle. Avoiding the acute angles prevents fibers or fibrous parts of the material to be treated from sticking.
  • the cams or teeth advantageously ensure excellent comminution of textiles, foils, waste paper, wood, etc., because considerable cutting and shear forces can be exerted on the material to be treated, which is clamped, so to speak, by these carriers. If the wall of the plate is smooth, the material to be treated could dodge very easily, so that the splitting tools of the rotor or the rotors would not find sufficient resistance.
  • a suitable configuration of the drivers is characterized in that the drivers are provided in the form of rings parallel to one another and at a distance from one another. It is then a type of internally toothed rings that are attached to the inner wall of the plate parallel to the base of the plate over the height of the plate.
  • the splitting tools of the rotor are then expediently arranged such that they each engage in the space between two rings. This favors the cutting and shearing activity described above, in particular when comminuting fibrous material.
  • drivers which are inclined at an angle are arranged on the inner wall of the plate against its axis of rotation.
  • the carriers convey the goods to be processed from the lower area of the plate at the bottom of the plate to the edge of the plate or inwards towards the processing tools, like a kind of segment-shaped screw.
  • a screen wall is arranged at a distance from the plate wall.
  • This measure is advantageous for treatment goods, in particular regrinds with a sieve-like consistency.
  • the ground material which has reached the desired fineness, exits through the sieve opening in the sieve wall.
  • a stationary hood is placed around the rotating container, in this special case, eg grinding container, which protects against accidental contact as well as open container for the fine regrind. In the lower area, this hood is preferably drawn together as a funnel, so that the fine material converging there can be fed into a conveying device.
  • the processing and comminution device shown in FIG. 1 has a rotatably driven plate 1 with an axis of rotation 2 and a bearing (not shown), which is located on the schematically indicated frame 3.
  • the plate, generally designated 1 has a plate wall 4 and a base 5, the material flow 6 of the material to be treated 6 being represented by the numerous arrows.
  • the rotors 21 and 22 have splitting tools 25 puf.
  • the embodiment shown here is a radially flared rod.
  • the rotors 21 and 22 rotate in the direction of the arrows 26, that is, in the opposite direction of rotation as the plate 1.
  • the five strong arrows 27 show the flow of the material to be treated 6 into the machine through the inlet opening 28.
  • the task material first falls through the inlet opening 28 onto the rotor 22 arranged on the right, whose axis of rotation 24 is higher than the axis of rotation 23 of the left rotor 21.
  • the material captured by this rotor 22 becomes to a large extent with considerable pre-acceleration hurled onto the rotor 21 and detected there by the splitting tools 25 with increased impact and tear force. The speeds add up here, so that good shredding forces work.
  • the rotor 21 throws the material 6 into the regrind layer which rises upwards on the plate wall 4, with an autogenous grinding again taking place.
  • the material to be treated which is transported upwards from the plate 1, is gripped and crushed in the inner layer by the left rotor 21 in the opposite direction.
  • the layer lying on the plate wall 4 on the other hand, is carried upwards and plunges back into the working area of the two rotors 21 and 22 at about the highest point of the plate 1 like a waterfall.
  • the circumferential speed of the plate 1 allows the throwing parabola of the falling material to fall can be controlled that the material falls mainly on the rotor 21 or predominantly on the rotor 22 or evenly distributed on both rotors.
  • Fig. 2 shows a top view and Figs. 3 and 4 the above-mentioned sectional views of the generally designated 30 outlet opening of the device shown.
  • the ground material 6 flows in the direction of the arrows 31 (FIG. 3) along the stationary cover 32 to the outlet opening 30.
  • a wedge-shaped deflector 33 leads somewhat in the direction of the interior of the plate 1, so that the material to be treated, in principle, passes through the gap 33 'between the outlet opening 30 or discharge flap 34 and the stationary cover 32.
  • FIG. 2 shows in the area of arrow 7 the free outlet opening 30, through which one can look into the plate 1, while the upper half of the outlet opening 30 is covered by a discharge flap 34.
  • This discharge flap 34 does not reach all the way to the edge of the plate on which arrow 7 lies. It is also inclined in the direction of flow (arrow 31) of the material 6 to be treated such that it projects somewhat into the plate 1 even in the closed state (FIG. 3). So that consequently the drivers 8 fastened to the plate wall 4 can move past the discharge flap 34, they require the free space shown in FIG. 2 for this purpose.

  • the gap 33 ' is completely covered by this flexible part 35, so that material to be treated cannot settle there.
  • the discharge flap 34 can be opened outwards to enlarge the opening width.
  • a load weight 36 and a pull chain 37 are used to regulate the flap position.
