Definitions

  • the present invention relates to a comminution machine according to the preamble of claim 1.
  • Such crushing machines are used for crushing from soft to medium-hard shredded material.
  • To this Purpose is an in with grinding holes closed working cylinder, mostly made of stainless steel consists.
  • This relative rotation can, on the one hand, be at a standstill Working cylinders through rotating tools and on the other hand with stationary tools by a rotating working cylinder are caused. You can also Working cylinders and tools each for themselves and each other rotate in opposite directions.
  • Such crushing machines can on the one hand in Batch operation run and on the other hand in a stationary or quasi-stationary process.
  • the machine housing is the shredder between a feed channel and a discharge channel involved.
  • the Feed channel for example from a hopper or The like exist while in the case of stationary or quasi-stationary Processes a continuous flow of material led to the shredding machine via the feed channel becomes.
  • Such crushing machines also need the occasional cleaning or maintenance.
  • axle shaft For constructive simplification reasons, one is overhung axle shaft preferred, simple bearing mounting for the axle shaft in the cover, however, is intended by the invention be included, at least as long as the axle shaft does not pierce the lid.
  • In-line means changing shredding machines that in a manufacturing chain between a supply channel and a Discharge channel are installed.
  • the working cylinder can be provided its front ends on the one hand in the machine housing and center on the other hand in the lid.
  • the Cover the double function over the hermetic seal of the Work area also the mechanically stressed working cylinder to fix so that the rotating relative to it Tools always the same wall distance to the working cylinder take in.
  • the Axle shaft practical there and in the adjoining work area be stepless.
  • the turning of the tools can be ensured via suitable positive locking connections. Exemplary embodiments are given for this.
  • the lid serves as an exclusive Locking part for closing the work area and can therefore be designed as a flat plate.
  • the lid provides an annular screw flange represents the flat in front of the head on an end face of the machine housing is screwed on.
  • the density of the mounting screws that means their mutual circumferential distance, is related to the respective force relationships in the work area adjusted so that the lid together with the machine company represents a practically one-piece rigid structure.
  • the main goal is to optimize the products and process properties of the materials to be shredded With regard to further processing.
  • the core of this shredding machine is one in itself closed working cylinder 4 circular cross-section, which in most cases is made of stainless steel and in has shredding holes 5 in each case.
  • the Wall thickness of the material so thick that an overall very stiff cage is created, which is opposite the machine housing 3 is permanently installed.
  • the material thickness of the working cylinder therefore ensures an iron-rigid structure within which the tools are 6 are located.
  • the tools 6 and the working cylinder 4 rotate relative to each other, so that in the area of the wall of the working cylinder 4 a shearing movement between the tools 6 and the shredding holes 5, where ultimately that Shredded material 2 is shredded.
  • axle shaft 7, around which the tools 6 turn around in principle coaxial to the longitudinal axis of the working cylinder 4 so that the path of the tools one to the working cylinder envelops 4 concentric cylinders an at most small distance 10 to the inner wall of the working cylinder 4 occupies.
  • the machine housing 3 of this shredding machine 1 is between a feed channel 13 and a discharge channel 14 a duct system connected, which in the simplest case from a hopper on the feed channel 13 and a discharge channel at the discharge duct 14.
  • the lower half cylinder 20 of the working cylinder 4 is on the discharge duct 14 connected so that the comminuted material on its material conveying path predetermined by gravity 18 19 fall down out of the machine housing 3 can.
  • the lid therefore offers a constructive conclusion of the Machine frame on that side of the comminution chamber, on which no constructive bearings, drive positions etc. are provided.
  • the lid can therefore be removed by simply loosening the Remove screws 26 from the machine housing in order to Take out the working cylinder 4 and, if necessary, the tools 6 to be able to.
  • the cover 22 closes a diameter 23 of the Opening in the machine housing 3, which is at least as large as the largest diameter 24 of the working cylinder, so that this easily removed from the interior of the machine housing 3 as soon as the cover has been unscrewed.
  • Figures 1 to 3 show that one end of the working cylinder 4 is seated in a centering device 27, which is provided fixed on the machine housing 3.
  • the centering device 27 sits in the area of the inlet opening of the feed channel 13 in the machine housing.
  • the other End of the working cylinder 4 is in a corresponding one Centering device 28 set, which is immediately on Cover 22 is located.
  • it stands between the centering devices 27 and 28 an axial distance one that is essentially the axial length of the working cylinder 4 corresponds, so that with the assembly of the cover 22 also Axial fixation of the working cylinder 4 arises.
  • An external rotary drive 31 is used for this purpose attacks on the circumference of the working cylinder 4.
  • the form-fitting Drive takes place here via a gear / pinion pairing, whereby the gear sits on the circumference of the working cylinder 4 and one Has outer diameter that is not larger than the diameter 23 of the cover-side opening in the machine frame 3.
  • the external rotary drive is also fulfilled here 31 of the working cylinder 4, the mountability of the cover 22 leaves unaffected.
  • the direction of rotation 33 of the working cylinder 4 results from the angular position of the tools 6, the for the Direction of rotation in the gusset between the tool Wing 9 and the inner wall of the working cylinder 4 are decisive is.
  • Fig. 1 shows a structurally very simple solution to 2 and 4 to 5.
  • An external rotary drive 32 serves as the drive the machine frame 3 is anchored.
  • the drive 32 sits on the feed channel 13 facing Side of the machine frame 3, so that the axle shaft 7th penetrates the feed channel 13.
  • axle shaft 7 is in the area of the feed channel 13 free of wave additions to the accumulation of material to prevent.
  • the rotor 8 in the axial direction a compensating movement within the Machine housing 3 can perform while he on the other hand the rotational movement of the axle shaft 7 must follow.
  • the rotor has a longitudinal groove which is the width of the feather key 35 is adapted so that the rotor in the axial direction the axle shaft 7 can ride. He adjusts himself so that the wings 9 between their cover-side transverse edge 36 and its machine frame side transverse edge 35 within the Fit the work area exactly.
  • This measure serves to avoid deposits, since the overflow zones of the tools 6 are always scraped free.
  • the working cylinder 4 conical is.
  • a working cylinder 4 is aligned that the lower surface line 40 is horizontal or below an angle of less than about 30 degrees to the horizontal is inclined.
