Definitions

  • a known device of this type (DE-OS 2 348 202) is used for the comminution of materials emptied in particular in latrines or other abortion systems, which are fed to the comminution device together with rinsing liquid.
  • the plate fulfilling a sieve function carries comminution tools in the form of upwardly projecting fangs and tusks, which are arranged in concentric circles and interact with a vertical counter knife supported above the plate as an installation part in the filling space.
  • the crushing effect on parts that cannot immediately pass through the openings in the plate occurs above the plate due to the interaction of the ripping and impact teeth with the counter knife, in which material taken by the teeth is pressed through the incisions.
  • the plate manages with a low circulation speed; however, only materials that can be easily torn with only a relatively low inherent strength can be shredded.
  • a shredding device for shredding paper, a shredding device is also known (DE-OS 2 432 603), which consists of a housing which is circular in cross-section and defines an upright, upright filling shaft accessible from above with a bottom as the bottom end of the interior of the housing, a discharge opening arranged approximately near the bottom for comminuted material and a sieve arranged upstream of the discharge opening and a disk-shaped tool which rotates in the interior of the housing and has an outer diameter which corresponds approximately to the inside diameter of the housing and is fastened to a drive shaft which extends coaxially through the bottom into the interior of the housing.
  • the sieve is designed as a sieve drum which coincides with the housing wall in the lower region of the filling shaft and is surrounded by an annular outer air duct. This opens into a retaining ring arranged outside the housing, and an exception sack for shredded paper on the one hand and an air filter on the other hand is attached to this.
  • the radial sieve holes of the sieve drum hold paper filled into the filling shaft inside until a size suitable for passage through the sieve holes is obtained in the course of a shredding process.
  • rotating shredding tools are provided in the lower region of the filling shaft, which are fastened on the drive shaft which extends coaxially through the bottom of the housing and the sieve drum into the interior of the housing.
  • a radially protruding disk on which there are radially protruding fan blades and radially protruding knives, is first attached to the drive shaft at a close distance above the bottom of the filling shaft.
  • a cutter disc is attached to the drive shaft, the outside diameter of which corresponds to the inside diameter of the stationary screening drum.
  • this cutter disc which is provided with inwardly directed slots approximately radially from the circumference of the cutter disc, is a second cutter disc which has the same design but has a smaller diameter.
  • a wing knife is then arranged above this upper knife disk, which consists of two opposing flapping wings projecting approximately radially from the drive shaft.
  • crushing devices For crushing other waste, namely more or less lumpy objects of greater strength and bulk, z. B. of wood or wood-like waste, as they occur in agricultural and forestry companies or in horticulture, crushing devices are used, which break up such waste with the help of knives into small pieces, which are then further processed, e.g. use as fuel. Such devices are sensitive, are subject to considerable wear and tear, deliver very non-uniformly comminuted goods and have only a limited output with a considerable construction and drive expenditure.
  • a chips for the preparation of cattle fodder is also known a chips (FR-PS 1 078 252), which comprises a circular cross-section, an upstanding, from above accessible filling shaft enclosing housing with a bottom as the bottom end of the housing interior, which is arranged with a floor level Discharge opening for shredded goods is provided.
  • a plate rotates, which has an outer diameter that corresponds approximately to the inner diameter of the housing, and is fastened to a drive shaft that extends coaxially through the bottom into the interior of the housing.
  • the plate which is arranged at a distance above the bottom and has blower blades on its underside, has four radial plates Slits as through-openings for shredded material, along the edge of which, in the direction of rotation of the plate at the rear edge, a chopping knife is provided which is inclined upwards in the direction of rotation.
  • a sieve segment which is arranged parallel to the peripheral wall of the housing and which can be rotated from an ineffective position adjacent to the discharge opening into a position in which the sieve is located in front of the discharge opening.
  • Such a shredder with shredded material to a certain extent, at rest in the shredder knife, which quickly revolves around the interior of the container free of internals, is only for soft, easily cut goods such as beets, potatoes or the like. fresh crops can be used, for solid materials it is necessary to have guides that come up close to the schnitzel level and form abutments. B. in the form of a feed chute and is unusable for shredding solid materials such as wood waste.
  • High-performance shredding machines are also known for shredding bulky wood or other waste or bulky waste parts (DE-OS 2928471), but such machines form very complex structural units for shredding waste from forestry and agriculture, horticulture and other wood processing companies such as carpentry etc. are too expensive.
  • the invention has for its object to provide a structurally simple, inexpensive to buy and operate shredding device that reliably shreds solid, especially wood and wood-like waste from forestry and agriculture, horticulture and woodworking small businesses essentially autogenously with high performance.
  • the device according to the invention branches and roots, shrubs and woody parts, straw and smaller pieces of solid wood waste can be processed into finely divided comminution material which is limited in terms of its degree of comminution.
  • the comminution device according to the invention based on such a device, is characterized by the features specified in the characterizing part of patent claim 1. With regard to essential further refinements, reference is made to claims 2 to 11.
  • the comminution device with its combined sieve and centrifugal plate rotating as the bottom end of the filling chute, realizes a comminution principle that turns away from everything known, which consists in the fact that the material to be comminuted in the filling duct above the sieve and centrifugal plate in cooperation with it the wall of the housing is set in a constant circulating movement, in which the parts to be comminuted cover a somewhat tumble-shaped circulating path, d. H. are moved radially outwards above the sieve and centrifuge plate, carry out an upward movement along the housing wall and then return in an inward and then downward movement to the inside of the filling shaft and hit the sieve and centrifugal plate again.
  • This movement which is loop-shaped in cross-section, is overlaid by a circumferential movement, and this circulation, in which the objects to be shredded constantly rub against one another and collide with one another, brings about a comminution of the objects by interaction between these objects until a particle size is reached which can pass through the sieve holes in the sieve and centrifuge plate are permitted. As soon as sufficient comminuted particles have passed the sieve holes downwards, they are thrown out directly through the discharge opening, if necessary also with the help of an air stream that forms through the filling shaft and the sieve and centrifugal plate and through the discharge opening.
  • the combined sieve and centrifugal plate essentially serves, in addition to the classification of the comminuted material, as a movement drive for the material to be comminuted in the filling shaft, which is then comminuted in the manner described above by mutual interaction during the circulation.
  • the comminution device comprises a housing 1 which is circular in cross section and, in the exemplary embodiment shown, cylindrical, which delimits an upright filling shaft which is accessible from above and has a bottom 2 as the lower end of the housing interior.
  • the housing can also, for. B. have the shape of an upwardly slightly diverging or converging circular truncated cone.
  • the housing can also be provided with a conical indentation in its lower region. This indentation forms a conical pocket through which something in the lower container region closes crushing material is increasingly pressed down on the outer circumference.
  • the crushing device can be set up on any base surface via a base frame 3.
  • a coaxial bearing device 4 is located on the underside of the base 2 of the housing 1 for mounting a drive shaft 5, which extends centrally into the interior of the housing and is provided at its lower end, for example with a pulley 11, via which the drive shaft 5 receives its rotary movement from a drive motor, not shown.
  • a plate-shaped tool 6 in the form of a combined sieve and centrifugal plate is fastened.
  • This sieve and centrifugal plate 6 has a closed circular peripheral edge and a diameter which corresponds essentially to the diameter of the housing at the level of the sieve and centrifugal plate 6, so that the peripheral edge with the housing has an edge gap 9 sealed against the passage of material to be shredded limited.
  • the sieve and centrifugal plate 6 is provided with axial sieve holes 8, which are only partially illustrated in the drawing. These sieve holes 8 can have a circular cross section, but instead an oval shape or the like. have and have a diameter or a maximum dimension that corresponds to the desired maximum particle size of comminuted material.
  • the sieve and centrifugal plate is advantageously provided with the sieve holes 8 in the area of its entire working surface facing the filling shaft, which can be arranged evenly distributed over the working surface.
  • the sieve holes can e.g. receive such a distribution that the distance between adjacent sieve holes 8 in the working surface of the sieve and centrifugal plate decreases from the inside outwards towards the peripheral edge, resulting in a concentration of sieve holes in the outer region of the sieve and centrifugal plate 6.
  • the working surface of the sieve and centrifugal plate 6 is essentially an annular surface, after in the central region of the sieve and centrifugal plate an upwardly projecting guide cone 10 is placed thereon, the significance of which will be discussed further below.
  • the sieve and spin plate 6 forms a flat, circular horizontal plate.
  • the sieve and spin plate 6 it is also possible to deviate from this structurally particularly simple and inexpensive shape and to give the sieve and spin plate 6 a shape in which the work surface is slightly conical with an upward or downward pointing cone tip, concave or convex arched or ring-shaped outwards is stepped.
  • Conveyor vanes 7 are arranged under the sieve and centrifugal plate 6, which circulate in the annular space between the underside of the sieve and centrifugal plate 6 and the bottom 2 of the housing 1 as centrifugal and blower vanes. These conveying vanes 7 are connected to the underside of the sieve and centrifugal disc and form approximately radially oriented stiffeners for the latter. It goes without saying that in the connection area between the sieve and centrifugal plate 6 and the conveyor vanes 7 the former is not provided with sieve holes 8.
  • a discharge opening 12 which is formed by the opening of a nozzle 13 connected tangentially to the housing 1.
  • a delivery line can be connected, in which a delivery fan is switched on.
  • Such a conveying fan forces an air flow from top to bottom through the filling shaft in the housing 1, through the sieve and centrifugal plate 6 and through the nozzle 13 up to a collecting container for comminuted material, but such an air flow is already formed solely by the with its conveyor blades 7 rotating sieve and centrifugal plate 6, so that an additional conveyor fan can also be omitted.
  • the housing 1 is provided with a bulge, which is associated with a magnet 16 for separating magnetic parts, such as nails or the like, as they can occasionally get into the filling shaft as part of wood waste
  • This bulge provides a slightly curved inner cover 15 which extends in the direction of rotation approximately to the center of the magnet 16.
  • the sieve and centrifugal plate 6 On its upper side, the sieve and centrifugal plate 6 is provided with at least one driver cam 17 in the region of its peripheral edge.
  • the sieve and centrifugal plate 6 carries two diametrically arranged driver cams 17, and the driver cam (s) can have a radial front face 18, which, as shown, is inclined backwards inward in the direction of rotation and which can also be equipped with a cutting edge.
  • a blunt front side on the flat driving cam 17 is sufficient, since this has the main task of increasing the conveying movements on the material to be shredded and of causing impact effects.
  • one or more flat knives 14, 19 can also be placed eccentrically on the top of the sieve and spin plate 6, which are in themselves unnecessary in the case of numerous goods to be shredded are, but also have a performance-enhancing effect.
  • flat knives 14, 19 are preferably used in pairs, each with a diametrical mutual arrangement.
  • the flat knives 14 are designed as piercing knives.
  • the piercing fingers 22 of such flat knives 14 have cutting edges 23 on their front end in the direction of rotation 24 of the sieve and centrifugal plate 6 at a distance above the working surface of the sieve and centrifugal plate, to which a retracted chip groove 25 adjoins on the underside.
  • the corresponding wedge-shaped piercing fingers 22 emanate from a comb-shaped knife back 26 facing away from the direction of rotation 24 and delimit between them spaces 27 which extend down to the working surface of the sieve and centrifugal plate and in the region of the knife back 26 from a wedge-shaped rising upwards End area 28 are limited.
  • the width of the free spaces 27 between the piercing fingers 22 preferably corresponds at least essentially to the maximum sieve hole dimension.
  • the flat knives 19 can also be designed according to FIG. 4 as a flat circular disk, which has a circular cutting edge 20 which extends at a distance above the working surface of the sieve and centrifugal plate 6 has and between this and the work surface has a circumferential, tapered or inwardly curved chip groove 21.
  • comminuted goods are filled as intended into the filling shaft of the housing 1, for. For example, up to a 2/3 the height of the filling shaft. If the sieve and centrifugal plate 6 is now set in rotation, the entire comminution material gradually reaches the trombone-shaped circulating movement described at the outset, namely by the centrifugal action of the sieve and centrifugal plate on the material coming into contact with it.
  • a hollow funnel is created in the circulated material mass in the central region of the filling shaft, and the guide cone 10 ensures that no material accumulations can be formed in the central region of the sieve and centrifugal plate 6, which can escape the circulating movement.
  • the comminuted material is self-crushing by rubbing against one another, beating and bumping, the desired crushing forces being increased by the impact effects of the driving cams 17.
  • the flat knives in turn contribute to a pre-shredding in the case of the comminution goods which are already more difficult to process, so that such goods also get into the circulation cycle.
  • Crushed pieces or particles that form during the self-comminution, the dimensions of which are less than the dimensions of the sieve holes 8 fall through or are pressed through the sieve holes 8 as soon as they strike the sieve and centrifugal plate 6 in the course of the circulating movements or glide over it.
  • the sieve holes 8 can be freely selected in terms of their shape and dimensions in view of the desired degree of comminution, etc., can be formed by cylindrical or slightly tapered bores and have edges at their transition into the working surface of the sieve and centrifugal plate, which in turn are in the comminution and conveyor drive senses act aggressively on the material to be shredded in the filling shaft.
  • the good particles passing down through the sieve holes 8 are captured directly by the conveying vanes 7 and flung out through the discharge opening 12, their discharge being able to be supported by the air flow mentioned above.
  • the obtuse-angled guide cone 10 not only prevents material accumulation in the central area, but also prevents plate-shaped pieces from being placed flat, so that even such objects repeatedly fall into the effective range of the flat knives 14 or 19 by tipping and undergo progressive pre-comminution.
  • the obtuse-angled cone design also prevents objects from jamming between the guide cone 10 and the wall of the housing 1. In the event of congestion effects, objects can also be retained or pressed from the outside inwards, which are then directed upwards through the outer surface of the guide cone and again be introduced into the goods movement.
  • the piercing knife 14 strikes very precisely delimited pieces out of larger objects and is therefore particularly suitable for almost all crushable and cutable comminution materials, especially since the free spaces favor breaking effects on machined objects which can lie in the chip groove 25 under the piercing fingers 22.
  • the flat knives 19 in circular form offer a comparatively longer cutting edge and have a more cutting effect on certain lumpy comminution objects and, owing to their round shape, a good penetration effect when passing through the circulated material flow.
  • the total pressure of the material mass in circulation on the sieve and centrifugal plate 6 is also increased.
  • the latter can also be composed of circular segments which are placed on the conveying vanes 7 as supporting skeletons and are individually connected to the conveying vanes 7, so that partial replacements are possible in the course of maintenance work.
  • two or more sieve and spin plates can be arranged coaxially one above the other.
  • the dimensions of the sieve holes can decrease from the uppermost to the lowest sieve and centrifugal plates.
