Definitions

  • the invention relates to a processing and crushing device, in particular for waste materials, with a rotatably driven plate and at least one eccentrically arranged, high-speed rotor, the direction of rotation of which is opposite to that of the plate.
  • 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 shredding device is already known for processing garbage and waste materials, which has the features of the type mentioned at the beginning.
  • the high-speed rotor used there is provided with at least one toothed disc, the plane of which runs transversely to the rotor shaft and is partially immersed in the material held on the container wall by supercritical speed.
  • 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 grinding, are held on the inner wall of the rotating container, which is driven at supercritical speed, and are broken up 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 invention is therefore based on the object of providing a preparation and comminution device of the type mentioned which, with the avoidance of load peaks and without additional machines, using simple tools allows processing, preparation, mixing and comminution of materials which are voluminous, can be bulky, coarse and hard, possibly even up to a fine-fiber or flour-like digestion of the particles.
  • the plate is driven at a subcritical speed and is provided with a stationary cover in which an entry device is arranged, that an outlet opening, preferably in the lower region of the device, is provided and that the rotor is directed in the direction several splitting tools are mounted at a distance from one another along its axis of rotation.
  • the entry device will be arranged in the upper part of the cover.
  • the material to be treated is reliably and uniformly brought up to the processing tools, so that a secure grasping is always guaranteed.
  • the device according to the invention is surprisingly insensitive to the loading with different materials in one operation in a colorful order, e.g. with filled sacks, then pressed bales, empty boxes and liquid and plastic components etc.
  • Favorable further areas of application are also the processing, crushing, drying and cooling of bound molding sands, drying of green fodder and similar materials, separation and recovery of plastic from waste, processing and recycling of animal breeding waste and waste materials from the metalworking industry, e.g. the processing of bulky masses of metal turnings.
  • the function of the device according to the invention could be described as "tearing"; because the impact limit of the material being processed is stressed using the impact, and tough materials are torn.
  • the versatility of use is considerably increased by the measures according to the invention compared to the known devices.
  • the material to be treated is no longer held on the inner wall of the plate by a supercritical speed, but is intended to crash consciously from a previously selected apex after being carried up to the shredding rotor.
  • a stillsthende cover prevents dust from escaping and L uftverschmutzung, the surroundings may protect against parts thrown out from the processing space of the device and allows the present invention preferred in some embodiments, substantially horizontal arrangement of the plate rotation axis. This ensures good circulation of the material to be treated and ensures that all material parts fall down one after the other.
  • the stationary cover enables the entry device to be arranged, which is preferably provided in the upper part of the cover and is large in size, so that bulky materials, for example garbage bags, can also be placed.
  • the overall structure of the device according to the invention is particularly simplified in that the outlet opening can be arranged in the stationary cover. As a result, special devices for regulating the size of the regrind can be provided at the outlet opening without great effort, as will be described below.
  • 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, for example radially arranged rods, teeth, baffle plates or other, possibly also armored striking tools, which stress the material to be treated with impact and tearing.
  • the invention is advantageously equipped 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.
  • 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. In a smooth Wa 7 of the plate could idung dodge the material to be treated very easily, so that the splitting tools of the rotor or the rotors would not find sufficient resistance.
  • An expedient embodiment 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 kind of internally toothed rings, which are attached to the inner wall of the plate parallel to the bottom 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.
  • the wall of the plate is frustoconical. In this way, even with a relatively small plate, a large direction of entry or a large covering hood is obtained, which allows the attachment of a large-sized entry device. Then bulky goods can also be processed. Due to the conical design of the plate wall, the bottom of the plate can advantageously be relatively flat, i.e. in the direction of the horizontal, and thus the dwell time of the loading. enlarge good for action.
  • the discharge conditions also improve due to the frustoconical plate.
  • the cone-shaped plate wall can be provided for certain tasks.
  • the jacket circumscribing the splitting tools of the rotor is a truncated cone. While in the case of the normal rotors, which are approximately cylindrical in shape, the axis of rotation in the case of the frustoconical Tel lers are to 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.
  • a screen wall is arranged at a distance from the plate wall.
  • This measure is favorable for treatment goods, in particular regrinds with a sieving consistency.
  • no outlet opening is then provided in the device according to the invention. All of the regrind that has reached the desired fineness emerges through the sieve opening in the sieve wall.
  • a stationary hood is placed, which represents both protection against accidental contact and affang vessel 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 conveyor.
  • a further preferred embodiment of the invention is characterized in that the outlet opening is designed as a discharge flap which is pivotally attached to the covering hood 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 facilities and features described without too much effort. Processes the Z ER-size reduction apparatus such as household waste and similar materials, then it is important that existing in the millbase textile shreds, films, etc. from seizing up at the corners and column adjacent to and on the Austragssö réelle and cause blockages.
  • the outlet opening constructed in accordance with the above features ensures trouble-free operation.
  • the inclined position of the discharge flap allows the material flow to be guided from the cover hood 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 if, 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 lower region of the ground material layer and the coarser material in the upper region of the ground material layer. 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.
  • 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 to the edge of the plate or inwards towards the processing tools, depending on the type of worm arranged in segments.
  • a plurality of closable outlet openings are provided in the plate wall in the vicinity of the plate base. Then the discharge device preferably arranged in the lower region can be omitted; because it is replaced by the outlet openings. If you work with the device according to the invention dry, granular material, such as stone split, it has been shown that the coarse grain often rolls against the outlet opening, while the fines collect to a considerable extent at the lowest point in the bottom of the plate. If the device according to the invention is used as a comminution machine, then the fine fraction is of particular interest; and devices must be provided to ensure its discharge. This takes place in a surprisingly advantageous manner through the outlet openings. These can be slit-shaped, round, oval or have any other design. The number of openings depends on the size of the device and the throughput capacity in question. It has been shown that two, three or four outlet openings are preferably distributed over the circumference of the plate.
  • the outlet openings can be closed by a ring which can be displaced in the circumferential direction with corresponding openings or by covers attached to double-armed levers, the end of the double-armed lever opposite the cover being provided with a roller held on a guide rail.
  • the plate has the same openings as the sliding ring.
  • the entire cross section of the openings or only a part can be released. In this way, the discharge quantity can be regulated.
  • the spout itself only takes place in the lower area of the plate. As a result, the sorting effect of the turntable is immediately used.
  • the guide rail is designed as a stationary curve ruler, preferably composed of interchangeable pieces, against which the roller is prestressed against the double-armed lever.
  • each opening has a pivotable end cover, which completely or partially releases the opening cross section of the outlet openings. If the guide rail or the curve ruler is moved at a distance from the base of the plate, the position of the drain cover also changes.
  • the arm carrying the cover is mounted on the outside of the plate base in a guide tube or a sleeve. In this there is a torsion spring which holds the lid in the closed position.
  • the roller already described is provided on the second arm of the lever and rolls over the curve ruler in the opening and closing zone.
  • the distance between the outer circumference, on which the covers are arranged, and the curve ruler arranged further inside is bridged via said bushings or the guide tube, as is also indicated below in connection with the drawings as an axis of rotation.
  • the opening time can also be varied by changing the length of the curve ruler. You can also insert or remove spacers and thus vary the opening time of the outlet openings.
  • both rotors are driven in opposite directions and are arranged in half of the plate with the direction of flow increasing. It has been shown that, especially when processing heavy materials, there is a tendency that larger pieces of material, even at a higher plate speed, are not carried out over the center of the plate (vertical center plane through the axis of rotation between the rising and falling material flow), but fall almost vertically just before the climax.
  • the device according to the invention then works with grinding balls. If the splitting tools of the rotors are designed accordingly, they can be used as spinning tools. Otherwise, other throwing tools made of highly wear-resistant material, e.g. Rubber or the like can be used.
  • the centrifugal rotor is driven and a mixture of balls and material to be treated is applied to it. Strong impact, pressure and circulation forces are already effective in the event of an impact. The same applies when the mixture of balls and material to be treated is thrown off the rotor.
  • the resulting throwing jet is shot into the thick layer of material to be treated, whereby the energy contained in the jet is converted into impact, pressure and friction work and results in an intensive grinding or comminution effect.
  • the acceleration imparted to the ball-treatment mixture can be chosen to be as high as desired. The upper limit is given by the strength of the ball material. The high acceleration allows the use of smaller grinding balls, whose contact and impact points - based on the ball weight - are many times higher than with balls of larger diameter and high dead weight, as are necessary with slow ball movement to achieve sufficient impact effects.
  • agitator balls The good effect of so-called agitator balls is known in milling technology.

  • the material captured by this rotor 22 is largely accelerated onto the rotor Thrown 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 22 throws the material into the regrind layer which rises upwards on the plate wall 4, with an autogenous grinding again taking place.
  • the material 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 falls approximately at the highest point of the plate 1 like a waterfall back into the working area of the two rotors 21 and 22. Due to the peripheral speed of the plate 1, the throwing parabola of the falling material can do so can be controlled that the material falls mainly on the rotor 21 or predominantly on the rotor 22 or evenly distributed on both rotors.

  • the drivers 130 have the primary effect that no undesired accumulations of material form at the lowest point of the plate. Since a certain distance is always kept between the rotors 21, 22 and the plate base 5 for safety reasons, the inclined drivers 130 cause the material to be treated to be guided almost 100% to the effective zone of the rotor or rotors. In addition, the discharge of the comminuted material is accelerated in the case of large throughputs, in particular if inclined drivers 130 reach close to the discharge opening.
