Definitions

  • the invention relates to a sorting device according to the preamble of claim 1.
  • the vertically arranged bottom of the sorting drum is designed as an annular storage wall which at a distance surrounds the mouth of a U-shaped feed chute which is open at the top. Good to be sifted into the feed chute is directed to the part of the sorting drum provided with holes (DE-OS 31 14 376 and 34 03 383).
  • the present invention is based on the object of largely preventing coarse material from getting caught on the sorting drum.
  • This object is achieved according to the invention by the features in the characterizing part of claim 1.
  • the coarse material introduced therein is deflected on the closed surface of the sorting drum and moved in the direction of the wall of the sorting drum. This movement together with the pulsating hydraulic pressure change when the sorting drum immersed in the accept material releases particles adhering to the sorting drum, the discharge conveyor device not obstructing the material to be sorted flowing into the sorting drum. With the aid of the device for deflecting the beam in the direction of the closed surface, the material introduced into the sorting drum can be guided in the desired direction.
  • the additional tube according to claim 5 can be dilution water be introduced into the sorting drum.
  • the object of the invention manages with a relatively small amount of dilution water.
  • the features of claim 6 prevent the through holes of the sorting drum from being reduced by the conveyor and thus tend to clog.
  • a sorting drum 1 shown in FIG. 1 has a cylinder jacket 2, a curved bottom 3 and a conically widening end piece 4.
  • the cylinder jacket 2 is provided with through holes 5, whereas the bottom 3, which is designed in particular as a dished bottom, is designed to be closed.
  • the end piece 4 In the area of the end piece 4 there is a helix 6 which extends at a central angle of approximately 360 °.
  • the sorting drum 1 is mounted with a tubular extension 7 connected to its base 3 in a roller bearing 8 which can be pivoted about a horizontal axis by the outside of its outer ring being mounted in a spherical section or its outer ring having coaxially arranged bearing journals.
  • a gear 9 is rotatably mounted, with which a pinion 10 of a gear motor 11 meshes, which is fixedly connected to the outer ring of the roller bearing 8.
  • the extension piece 7 is penetrated by an inlet pipe 12 with a smaller diameter, which has an end cover 13 in the interior of the sorting drum 3 and, on its jacket, one of the openings 14 facing the lower side of the dished bottom in the drawing.
  • the inlet pipe 12 is associated with an auxiliary pipe 15, which opens in the area of the mouth 14 and at which the end facing away from the sorting drum 1 protrudes radially outwards.
  • the sorting drum 1 is arranged during operation with an inclined axis and dips in the area of its bottom 3 and its adjacent part of the cylinder jacket 2 in a waste material located in an overflow container 16.
  • An outlet attached to the underside of the overflow container 16 is designated by 17.
  • a pulp suspension is introduced via the inlet pipe 12, from which coarse particles are separated out in the sorting drum and conveyed to the outside via the helix 6.
  • dilution water can be supplied via the auxiliary pipe 15.
  • the pulp suspension and possibly the dilution water is or are introduced into the sorting drum 1 via the part of the cylindrical part of the closed bottom 3 located just below and move longitudinally from the lower part thereof, which forms the lower sieve surface immersed in the sump of accepted material.
  • a pulsating hydraulic pressure change is generated by the rotating sorting drum. Coarse matter which has separated out of the solid matter suspension is separated out with the help of the helix 6.
  • FIG. 2 corresponds in substantial parts to the embodiment of FIG. 1, so that the same parts are provided with the same reference numerals, modifications being denoted by the letter o.
  • the sorting drum 1a which is arranged with a horizontal axis, has a cylinder jacket 2a, which has a cylindrical part 18 and, on the side facing away from the base 3, a conically narrowing part 19 which ends in a tubular end piece 4a.
  • a conveying helix 6a which is only arranged approximately at a central angle of 270 °, is provided in the end piece 4a and in the conical part 19 are inclined arranged blades 20, which serve in the same way as the helix 6a for discharging coarse material.
  • the mode of operation of the second embodiment corresponds to the mode of operation of the first embodiment.
  • the sorting device according to FIG. 3 additionally has a rocker arm 21 and a rocker drive 22 compared to the design according to FIG. 1.
  • the rocker arm 21 is pivotally mounted on a bearing block 23, which is located on the side of the overflow container 16 facing away from the inlet pipe 12.
  • the roller bearing 8 is arranged, on the outer ring of which the oscillating drive 22 engages, which has a crank 24 and a stationary crank wheel 25.
  • a rocker arm 21 is provided on each side of the sorting drum 1.
  • a sorting drum 1 is provided, the bearing 8 of which is arranged on a lever 21 in the same way as in the third embodiment according to FIG. 3.
  • this lever is not mounted directly on the bearing block 23b but by means of an articulated rod 26.
  • An additional articulated rod 27 is located between a base plate 28 and the central part of the pivot lever 21. This results in a 4-articulated chain, whereby the end piece 4 can be swiveled to the right in the drawing when the base 3 is raised.
  • a hydraulically or pneumatically actuated working cylinder 29, which is arranged between the base plate 28 and the outer ring of the roller bearing 8, serves to move the pivoting lever 26.
  • a rocker arm 21 and joint rods 26, 27 are provided on both sides of the sorting drum 1, a rocker arm 21 and joint rods 26, 27 are provided.
  • the inlet pipe 12b is led from the end piece 4 to the bottom 3, the same applies to the dilution water Auxiliary pipe 15b.
  • the mouth of the two pipes 12b, 15b is located above the currently lower part of the bottom 3, so that the closed surface of the bottom 3 is acted upon when a pulp suspension and possibly auxiliary water run in.
