Definitions

  • the invention relates to a method for treating compost, biomass or the like.
  • Feed material on a sieve surface the meshes or sieve holes of which are arranged in the direction of the flow of the feed material in at least two zones of different mesh or hole size, the feed material for separation in at least two grain fractions are first given to the zone of narrower mesh or hole size and then conveyed to the other zone / s.
  • the invention also relates to a device with a sieve drum, the sieve holes of which are provided in at least two different sizes in areas of the same hole sizes, the sieve holes in the axial direction of the sieve drum having decreasing hole sizes or cross sections from one end face to the other end face, and in particular for Implementation of the above method can be used.
  • DE-A-24 36 543 discloses such a device for processing waste, the sieve drum of which is rotatable about an inclined axis and has a polygonal cross section with two hole sizes and an inlet assigned to the narrower holes.
  • a drum section without holes should be able to be used as a fermentation drum.
  • EP-0082815 also describes a drum for processing municipal waste with two zones of different wall openings, the narrower of which connect to the inlet.
  • a horizontal shredding drum which also offers two different wall hole diameters, is equipped on the inside with helical curved wall baffles and a conical discharge.
  • an i. w. Sieve drum formed from rings, which has an open and a closed end assigned to a conveyor, eccentrically on a bearing block in order to be able to adjust the throughput time for the beets and thus the cleaning time.
  • the screening drum of the device according to the invention is pivotably mounted approximately in the middle of its length at an angle of inclination, with one end of a conveying member being assigned to each drum end.
  • the corresponding small grain fraction is sieved out; subsequently, depending on the number of the hole width differences connected in series, several fractions are formed. However, if the feed material is introduced at the front of the drum that adjoins the largest hole width, the middle fraction whose upper limit is determined by that largest hole width is screened out.
  • the sieve drum open at both ends and to provide it with inlets protruding into its interior with an associated feed element.
  • This feed element determines the respective desired front face of the task, and it can also be assigned an approximately central task.
  • the conveying direction of the feed material can be determined by a reversible conveying element, for example a transport scoop which moves in the desired direction inside the drum and which can convey from the small to the largest perforation and vice versa.
  • a reversible conveying element for example a transport scoop which moves in the desired direction inside the drum and which can convey from the small to the largest perforation and vice versa.
  • An embodiment according to the invention is preferred in which the sieve drum is pivotably mounted at an angle of inclination, approximately in the middle of its length, so that the direction of inclination can determine the direction of conveyance.
  • blade plates are also attached in the interior of the drum, which protrude radially into the interior if necessary and to which transport blades can be assigned.
  • the latter preferably have edges inclined towards the drum axis and can themselves also be inclined towards the drum axis.
  • the radial plane of the sieve drum laid through the pivot bearing is preferred with respect to its built-in plane of symmetry; the different diameters of the sieve holes can be provided on both sides of the radial plane of the sieve drum through the pivot bearing.
  • a sieve drum 1 of length n is centered on a - supported by a base frame 26 - inclination adjustment drive 8 so that it according to the horizontal position.
  • Fig. 1 in a dashed right - and accordingly in a left - tilt position can be transferred.
  • Piston / cylinder units 5 are used for this.
  • This drum 1 is compost, biomass or the like. Raw material is fed via an overlying distribution conveyor belt 6, which takes over this heap from a feeder 7 which is positioned in the middle.
  • Vertical supports 9 of the base frame 26 each hold an inlet funnel 10 or 10 m of an inlet chute 11 or 11 m , which protrude into the open left or right cone end 1 k of the screening drum 1 in FIG. 1.
  • inlet funnels 10, 10 m are provided above the drum axis A, their closed inlet chutes 11, 11 m protrude into the drum interior 1 i ; the feed material can be introduced into the screening drum via the horizontal axis A. After passing through, the feed material is discharged at the other end through built-in discharge blades 13 (FIG. 4).
  • the screen drum 1 On the screen drum 1 are in the selected embodiment on the left drum half perforated screens mounted with large screen holes 14, however, those 15 on the right drum half having smaller sieve holes In the shown in Fig. 1 position the hopper reaches 10 m supplied Hauferk or its finer screen fraction In a next coarser material arranged below the sieve drum 1, the next coarser material is brought through the sieve holes 14 into a left-hand receiving chamber 17, and the oversize is transferred via the discharge blades 13 described into an outer box indicated at 18.
  • the throughput time of the material to be screened can be slowed down or accelerated.
  • Material fed in on the left-hand side of FIG. 1 first reaches the coarse-meshed drum side with the coarse perforations 14 and flows over the in the arrow direction x to the discharge 12 (arrow in FIG. 1).
  • the fine fraction contained in the coarse fraction is discharged beforehand through the screen holes 15; it creates a middle fraction.
  • the screening drum 1 has continuous, continuous blade plates 19 which constantly raise the feed material and hurl it onto the opposite screen surface. This process is in turn adapted to the desired requirements by setting high-speed or slow-speed.
  • the transport blades 20 have a special shape, thanks to which e.g. Gauze bags or paper bags or the like. torn open by the blade plates 19 and the transport blades 20 assigned to a point and the contents of which are emptied.
