Definitions

the invention relates to a device for comminuting commercial or industrial waste, in particular for comminuting paper, wood, plastic and the like, in an embodiment according to the preamble of claim 1.
Crushing devices of the type described above are known in very different designs. If such devices are used to shred commercial or industrial waste such as wood to a certain extent, it is e.g. B. known to provide several sequentially arranged crushing stages or plants. In addition, it is e.g. B. in granulators known to combine a shredding unit with a screening device in order to obtain a comminuted material in the desired size or consistency.
Such conventional comminution devices have the common disadvantage that between the comminution stages or between the comminution unit and the classification devices of the comminution material, paths have to be traveled or distances have to be overcome, which is usually to be accomplished by gravity or centrifugal force.
the shredded material is effective and classified to the desired size.
the classification form recesses in cooperation with the pocket form recesses, ensure that the comminuted material is only transferred to the product exit area when it has reached a desired comminution dimension, without special classification units or further comminution stages being required for this.
the pockets, or else the classifying shape recesses can optionally be provided both in the driven comminution tool and in the stationary comminution tool or rotating at a lower peripheral speed.
one or more pockets can be arranged both towards the product filling area and towards the product exit area.
the classification form recesses are preferably designed and grooved kept open both to the filling area and to the exit area, the width, depth of the grooves and the like of which can be used to easily influence the classification or comminution result in a structurally simple manner.
the comminution tool having the pocket recesses is preferably a rotatably mounted, driven rotor knife with an essentially disk-shaped shape, which rotates centrally within a disk knife designed essentially in the form of a ring with a vertical axis of rotation.
Both stationary and rotor knives can be made relatively narrow overall, and the driven rotor knife can be driven from below in such a way that it is mounted directly on the drive shaft of a reduction gear.
the stationary knife and the rotor knife preferably separate the material filling space from the outlet area.
the comminution device as a whole for comminuting commercial or industrial waste comprises a receptacle with preferably a vertical container main axis, which can pass into a funnel in its lower region.
the comminution unit is expediently arranged in the region of the transition into the funnel shape, so that the outlet area with an outlet opening is located below the comminution unit, so that the material feed space or material filling space located above the comminution unit within the receptacle from the outlet region of the container through Cutting unit is separated.
the cutting unit should have a drive motor with a drive shaft and a reduction gear, the drive shaft of the cutting unit and the output shaft of the reduction gear having an essentially vertical axis of rotation which expediently coincides with the main axis of the container.
the cutting mechanism of the shredding device has a first shredding tool, which in the illustrated exemplary embodiments is a rotatably mounted rotor knife 1 which can be rotated by means of the drive.
This rotor knife 1 has an essentially disk-shaped shape with a circular outer circumferential surface 2 and is arranged within the second comminution tool (FIG. 5), which in the illustrated embodiment is designed as an annular disk-shaped standing knife 3 with a circular inner circumferential surface 4.
the rotor knife 1 is to be driven from below and therefore from the exit area of the comminution device, the rotor knife 1 being able to be mounted directly on the output shaft of a reduction gear (not shown) due to the overall narrow construction of both the rotor knife 1 and the stationary knife 3.
Level knife 3 and rotor knife 1 separate the material filling space of the receptacle from the exit area of the comminution device, so that the comminuted material can only leave the comminution device when it has passed rotor knife 1 and level knife 3 in total.
the rotor knife 1 is provided with the pocket shape recesses 5 and 6, respectively.
a total of two pocket shape recesses 5, 6 are provided, the shape recess 5 being arranged at the top and thus assigned to the product filling space and the other pocket recess being assigned to the bottom and therefore the product outlet area.
These pocket recesses 5, 6 are essentially semicircular in cross-section and work with the class approximately 7, z. B.
the pocket shape recesses 5, 6 and the classification shape recesses 7 form counter-profiles which, on the basis of the shape and size selected, represent the classification dimension and thus the size or quality of the material to be crushed.
the comminution material can be comminuted to a degree such that it corresponds to a granulate or regrind by simply designing pockets or classification grooves.
the number of pocket recesses 5 and 6 is also expediently to be selected taking into account the size of the comminution material to be fed and the circumferential dimensions of the selected knives.
the pocket-shaped recesses 5 and 6 are formed in that an inclined disc forms the rotor knife 1, on the upper side of which tooth-shaped attachment pieces 8 with cutting edges 8.1 are provided.
pocket-shaped recesses 5 and 6 are provided on the top side, ie, towards the filling area.
cutting edges 5.1 in each pocket recess 5 Due to the double arrangement of cutting edges 5.1 in each pocket recess 5, cutting edges are provided for a direction of rotation in as well as counterclockwise.
the pocket shape recesses 5 and 6, in particular, however, the pocket shape recesses 6, are inclined or curved from the bottom surface to the classification shape recesses 6, so that, in cooperation with the classification shape recesses 7, they have a downward effect.
the rotor knife 1 can also be preceded by a preliminary crusher which is formed, for example, by a toothed, inclined plate, as is illustrated in more detail in EP-OS 0 285 011.
the comminution material passes from the filling space of the receptacle into the pocket shape recesses 5 of the rotor knife 1 facing or assigned to the material filling space depending on the length and depth of the classification recesses 7 cut, cut or ground.
the separated comminuted material is then transferred to the pocket recess 6 assigned to the outlet area when it is in front of the classification mold recess holding the separated comminuted material 7.
the separated comminuted material is then conveyed to the material outlet area in accordance with the shape of the pocket shape recess contour. This is possible in particular because the separated comminuted part expands and can be grasped in the lower pocket 6 after the comminution process.
the pocket recesses 5 and 6 and the classification shape recesses 7 can optionally be provided both in the driven shredding tool and in a stationary shredding tool or rotating at a lower rotational speed. At low speeds or with a smaller knife diameter, it is advantageous to make the pocket recesses, as in the exemplary embodiments shown to provide in the rotor knife 1. At higher speeds and larger knife diameters, the provision of pocket-shaped recesses 5 and 6 in the stationary knife has advantages, since the centrifugal force can also be used to eject separated comminution material during ejection. In this case, the corresponding classification shape recesses are to be provided in the rotor knife in an analogous manner.
FIG. 6 shows an embodiment of a cutting tool provided with classification recesses, which has two standing knives 3, 3.1 arranged one above the other.
the upper level knife 3.1 with the order of magnitude of the groove-shaped classification recesses 7.2 serves as a rough level meter for pre-cutting.
the standing knife 3.1 below with its classification form recesses 7 is used for a refining cut of the feed material and has, for example, a design as shown in FIG. 3.
the rotating comminution knife used here only needs to have pocket-shaped recesses which are open at the bottom in the area of the standing knife with the smallest classification recesses.
FIG. 7 shows a comminution tool in a helical segment-shaped design. This can be driven in rotation for one direction of rotation.
the helix can be single or multi-start.
the cutting edges 5.1 work together with the standing knife having the classification shape recesses.
the cutting edge 5.2 of the end face works suddenly without a counter cutting edge. The circumference of the screw and thus the outer surface of the rotor knife separates the upper and the lower cutting space.
