Definitions

  • the invention relates to a hammer crusher for crushing metal scrap, consisting of a housing in which a hammer rotor rotates with rotatable hammers, with a material inlet arranged on the upward rotating side of the rotor, a classifying grate and an impact shaft open towards the hammer rotor.
  • a hammer crusher of this type is known from German patent specification 27 13 177.
  • the crushing of the often bulky scrap, such as car bodies or medium-weight mixed scrap, takes place both through the interaction of the rotor hammers with anvils arranged at a distance from the impact circle of the hammers and through impact of the material on the inner walls of the impact shaft against which the material is thrown .
  • the rotor hammers are freely rotatable in freely selectable number and distribution on axis rods arranged parallel to the rotor shaft and are arranged at a distance from one another on the circumference of the rotor.
  • the upper edge of the material inlet opening is part of an exchangeable anvil and is brought up to the gap in the hammer impact circle; a further anvil can be located on the lower edge of the baffle chute side wall adjacent to the product outlet and thus - seen in the direction of rotation of the rotor - above the grating of the product outlet opposite the product inlet.
  • the hammers cut or tear off material parts from the metal scrap fed in with the anvil at the material inlet as a counter-tool and hurl these parts against the walls of the hammer rotor with its lower opening spanning the material inlet to the material outlet to the impact shaft.
  • This deforms e.g. impacting sheet metal parts with detachment of adhering impurities with simultaneous material compression, while more solid metal parts are deformed less, but are also freed of adhering impurities before they are picked up again by the hammers before the material exits.
  • the rotor is usually driven relatively slowly when processing heavy goods.
  • the invention has for its object to improve a generic hammer crusher so that the susceptibility to failure is reduced without affecting the crushing result.
  • the wall of the baffle duct opposite the product inlet is a pivotable, together with a classifying grate reaching to the housing bottom, resilient, automatically swinging out outlet wall.
  • the housing base can be designed as a pivotable, resiliently flexible, automatically swinging grate rocker.
  • the outlet wall When the outlet wall is positioned close to the rotor, the metal scrap fed into the closed impact shaft undergoes intensive impact treatment Exposed to cleaning and compaction of the material; Material brought to the opening dimension of the grating of the outlet wall can escape to the outside, while material which has not yet been sufficiently comminuted and compressed is further exposed to the comminution process and undergoes at least one further comminution cycle.
  • the outlet wall can be set at a correspondingly large distance from the rotor.
  • the entire comminution material with the heavy coarse particles contained therein is safely conveyed to the outside via the gap between the swinging outlet wall and the rotor, so that no coarse particles can get into the bottom area of the hammer crusher; a placement of the rotor hammers on a heavy coarse part and thus damage to the axle rods or the rotor itself are prevented.
  • a gap which is large enough to be able to be set also in the area of the housing base Coarse parts can fall out downwards.
  • outlet wall and the grating rocker are preferably mounted on pivot axes guided through the housing to the outside and at least one end of each pivot axis is provided outside the housing with a lever arm which is engaged by a hydraulic cylinder, then the spring-loaded, automatically swinging mounting of the outlet wall and / Arrange a pressure relief valve in the pressure line of the hydraulic cylinder.
  • the end of the grating rocker facing the classifying grate of the outlet wall - as the grating rocker is curved - has an anvil. If a heavy coarse part should not have been conveyed outward through the opening gap when the outlet wall swung open, such a coarse part is either further crushed on impact with the anvil before it then reaches the area of the bottom-side grating rocker which forms the outlet for the product, or that Most of the radial force exerted on the anvil is so great that the rocker arm swings open resiliently.
  • the housing base and the outlet wall with their underneath the baffle shaft are set approximately at the height of the impact circle of the rotor hammers and extend at least as far as possible to the grating rock that extends to the horizontal plane containing the rotor axis hired to the rotor.
  • a hammer crusher 1 has a housing 2 which is anchored to a substructure 4 by means of supports 3.
  • a hammer rotor 5 rotates in the direction of rotation 6, the shaft 7 of which on both sides in on bearing blocks 8 attached bearings 9 is mounted (see. Fig. 2).
  • the hammer rotor 5 consists of a plurality of rotor disks 11 lined up at a distance on the shaft 7, between which hammers 12 are rotatably held on axes 13 which penetrate the rotor disks 11 at a radial distance from the shaft 7 and parallel to it.
  • the shaft 7 is connected to a drive via a coupling (not shown).
  • a good inlet 14 and a good outlet 15 are provided in the housing 2.
  • the material inlet 14 is arranged on the upward rotating side of the hammer rotor 5.
  • the upper edge of the material inlet is part of an exchangeable anvil 16 and is brought up to close to the hammer impact circle 17 of the hammer rotor 5.
  • an upper and a lower feed roller 19, 21 and a precompression wall 22 are connected upstream of the crop inlet 14.
  • At least one swivel cylinder 23 engages the precompression wall 22, which pivots the precompaction wall 22 out of its out-of-service position, shown in dash-dotted lines, into the supply duct from above and pre-compresses the material (metal scrap) and reduces its volume.
  • the nip 24 between the feed rollers 19, 21 is adjusted in accordance with the degree of precompaction; the upper feed roller 19 is therefore supported in a pivot lever 25 which allows the adjustment of the roller gap 24.
  • the part of the housing lying above the hammer rotor 5 is designed as an impact chute 26 which is only open at the bottom.
  • the baffle shaft 26 is covered with a cover wall 27 extending tangentially to the direction of rotation 6 of the hammer rotor 5.
  • the height h of the impact shaft is approximately D / 2 to D of the hammer rotor 5.
  • the diameter D of the hammer rotor is approximately between 1.5 m to 2.5 m. With a smaller D, the dimension h more closely corresponds to the dimension D, while with a larger D, h approaches the dimension D / 2.
  • the good exit 15 is designed in several parts; it consists of the material inlet 14 opposite, designed as a pivotable outlet wall 28 with a grating 33 end wall of the baffle shaft 26 and a grate rocker 29 of the housing base 32.
  • the housing base 32 has a subsequent in the direction of rotation 6 of the grate rocker 29, extending to the product inlet 14 Bottom shell 31.
  • the outlet wall 28 of the baffle shaft 26 extends with its wall extension designed as a classification grating 33 to the housing base 32; the grating 33 is placed below the baffle shaft 26 and above the hammer rotor 5, approximately at the height of the hammer stroke circle 17 and, like the grating rocker 29 and the bottom shell 31 of the housing base 32, runs in an arc shape.
  • the classification grate 33 ends in the immediate vicinity in front of an anvil 34 of the grating rocker 29.
  • the anvil 34 lies with its upper edge facing the direction of rotation 6 of the hammer rotor 5 below the horizontal axis 35 passing through the rotor shaft 7.
  • Both the outlet wall 28 and the grate rocker 29 are supported on pivot axes 36, 37 which are guided outwards through the housing 2.
  • the pivot axes 36, 37 are provided with lever arms 39, 41 on their two axis ends 38 lying outside the housing 2, to each of which one Hydraulic cylinder 42 attacks (see. Fig. 2).
  • the hydraulic cylinders 42 are with their rear ends in bearing blocks 43 of the housing 2 (see FIG. 2) or bearing blocks 44 in the area of a dust extraction 45 of the housing 2 and with their piston rods 46 on the lever arms 39, 41 of the outlet wall 28 or the Rust rocker 29 articulated.
  • the outlet wall 28 with its classifying grate 33 and the grating rocker 29 can be opened from the closed operating position shown in solid lines in FIG. 1, in which they are placed as close as possible to the impact circle 17, in the open operating positions shown in FIG. 1 with dash-dotted lines, Adjust the swivel positions that are swinging away from the hammer rotor 5.
  • a pressure relief valve 48 which is connected to a tank 51 by a line 49, is arranged in each case in the pressure lines 47 opening in front of the loaded piston surfaces of the hydraulic cylinders 42, not shown.
  • the valves 48 allow a spring-deflecting arrangement of the product outlet 15, i.e. the outlet wall 28 and the grate rocker 29, and not only when these parts of the product outlet are in the closed operating position shown in solid lines in FIG. 1, but also in the pivoted-out - as indicated by dash-dotted lines - operating positions.
  • the hammers cut or tear off 12 material parts from the supplied material and hurl the parts tangentially into the baffle shaft 26, essentially onto the top wall 27 arranged above the baffle shaft 26. This deforms the impacting shot parts in the sense of agglomeration. Material parts that are small enough in size and ge with sufficient speed exactly in the grate openings of the grating 33 of the outlet wall 28 are thrown, the outlet wall 28 or the grating 33 pass immediately.
  • a coarse part that is not conveyed away via the outlet wall 28 or the classification grate 33 is further reduced; if, however, it should still not have been comminuted so that it can be discharged through the openings of the grate rocker 29, the grate rocker 29 also yields resiliently and automatically by one of the thickness of the coarse part due to the pressure relief valves 48 arranged in the pressure lines 47 of its cylinders 42 corresponding gap.
  • the coarse part is ejected without blocking the hammers 12 and / or the hammer rotor 5.
  • the outlet wall 28 with the classifying grate 33 and the grating rocker 29 can not only be preset in the desired opening positions, but it is also possible for them in any operating position to yield resiliently in the direction of rotation 6 of the rotor 5.
  • such outlet openings can be set from the outset in accordance with the material that is fed in that heavy and coarse components are removed from the comminution process at desired points; if large parts still remain in the shredding process and are pulled by the hammer rotor 5 in the direction of rotation 6, the outlet wall 28 with the classification grate 33 and / or the grate rocker 29 can move away from the hammer rotor 5. Wedging of the coarse parts between the hammer rotor 5, the material outlet 15, i.e. the outlet wall 28 or the grating rocker 29 is thus prevented.
