Definitions

the present invention relates to a crushing device according to the preamble of patent claim 1.
the aforementioned device is relatively large and can not be connected to existing production without major adjustments. Another disadvantage is that the device can not be integrated into a pneumatic conveying path.
DE-U1-297 24 035 shows a crushing device according to the preamble of the claim.
statorfeste cutting unit and the rotor unit are installed as individual components in the device housing, which complicates and increases the cost of assembly, disassembly for maintenance and Einjust Schlieren the cutting unit. As a result, long downtimes occur at the associated production facilities, which are not sustainable.
stator and the cutting rotor as a replaceable Cutting unit are formed and this unit is mounted laterally displaceable in the housing and fixable.
the mentioned in claim 1 cutting unit is designed in the manner of a cassette and can, as u.a. is known by printers, easily and if necessary without prolonged service interruptions - and especially without readjustment - replaced and put into operation.
the system operator has at least two cassettes, then he can revise the replaced cassette in peace, d.i. Clean, regrind the knives and preferably also replace the bearings.
the built-up of a few parts device is extremely compact and possibly allows their structural adaptation to new tasks, i. It is also suitable for crushing future, new materials.
the design of the cutting rotor according to claim 3 ensures a high material throughput through the Cutting unit, without stability losses and / or vibrations, even at high drive speeds.
stator according to claim 6 Since the material throughput between the two webs is optimal and thus the stator in a revision with a few simple steps can be dismantled and reassembled.
the axis of rotation is designed according to claim 9, which allows a periodic dry cleaning but also a wet cleaning. In the same way also bonded and / or jammed materials could be solved and then further processed.
the flat end faces mentioned in claim 10 are used for improved transport of the conveyed material in the direction of flow or in the suction direction and prevent clogging of the cutting rotor with conveyed material and its chaff.
Fig. 1 1 denotes a comminution device, which can be installed in a pneumatic conveying path.
a drive 5 On the opposite side guide grooves 6 can be seen, in which a trained as a cassette, complete separating unit 10 in the direction of arrow E can be inserted and locked in a conventional manner.
the front side is placed on the axis of rotation 31 of a cutting rotor 30, the counterpart to the motor-side jaw clutch, this is denoted here by 33b. It can be seen on the cutting rotor 30 inclined cutting blade 32, which are peripherally supported in later-described carrier discs.
the rotor 30 is guided at both shaft ends in bearing flanges 23; the flanges 23 are detachably connected by an upper web 21 and a lower web 24 and form the stator 20 of the cutting unit 10.
the sectional view Fig. 2 shows the built in a pneumatic conveying system 40/41 crushing device after Fig. 1 , where the conveyed material FG and the chaff H are conveyed in a notoriously known manner by means of vacuum - p (vacuum).
the vertical sectional plane is placed in this drawing in the central axis (symmetry axis) of the parts 3 and 4.
the direction of rotation of the cutting rotor 30 is denoted by d and corresponds to the conveying direction of the goods to be chopped FG.
Fig. 3 the extremely simple construction of the stator unit 20 emerges.
oversized bearings 25 are installed with sealing washers (type 2RS), which are easily interchangeable in a revision.
sealing washers type 2RS
the U-shaped web 21 engages the front in an open-topped receiving bore 26 and can be adjusted by an adjusting screw 28 and fixed by a fixing screw 29; see. Fig. 5 ,
Fig. 4 also oblique bores 34 in the side supports 32b, which supply in operation the necessary between the bearing flanges 23 and the supports 32a air gap with an air flow (compressed air) and thereby free from cutting dust.
the axis of rotation 31 is formed as a hollow shaft, so that at the frontal bore a scavenge line 36 can be connected. The flushing medium can then escape through a plurality of small transverse bores 35 and release stuck Hiereselteile H. This procedure is used periodically, for example, depending on the conveyed material FG and its cutting behavior.
the desired cutting gap can be set very easily and precisely on the removed cutting rotor 30.
the two-sided receiving holes 26 is ever an at least partially prismatic step pin 27, one side of the U-shaped web rests on the pin 27 and is - in the manner of a rocker - with the Adjusting screw 28 adjusted in its free height, such that the cutting blade 32 can rotate easily.
the thickness of the conveyed material FG and its toughness are empirically taken into account.
the stepped bolt 27 is inserted differently in order to set the cutting gap to the optimum height.
FIG. 6 shows a lower web in a sectional view with a firmly inserted additional cutting blade 32 ', with a cutting edge 32 ".”
the stationary cutting blades according to FIG. 5 be made adjustable, which can be beneficial for very tough conveyed FG. All cutting blades are preferably made of carbide and ground to match.
the vorgenanten embodiments are designed for a dry conveyed FG;
the subject of the invention is not limited thereto. It could be installed with appropriate design adjustments in a hydraulic system with a liquid medium.
