Definitions

  • the invention relates to a sieve device, in particular for sorting waste material, with a sieve surface movable by means of a drive.
  • the object of the invention is to further develop screening devices, in particular with regard to their suitability for sorting waste material, especially organic waste material such as compost or the like.
  • the invention consists in that the movable screen surface is designed as a rotating screen drum with a lying drum axis and that a fixed, non-rotating guide device for the material to be sorted is arranged within the screen drum.
  • a back and forth, essentially flat screen surface is provided, which moves relative to a fixed guide device for the material to be sorted.
  • the guide elements of the guide device are preferably designed as baffle bars, which are arranged at a short distance from the movable screen surface, i.e. almost touch it, the material transported by the movable screen surface being jammed and circulated on the baffle bars, thereby improving the screen efficiency and sorting effect , so that among other things the dimensions of the movable screen surface, e.g. the axial length of the rotating screen drum can be reduced.
  • Fig. 1 shows a side view (partially sectioned) of a screening device with the screening drum lying
  • Fig. 2 is an end view of the inlet side
  • Fig. 3 shows a cross section through the screening drum according to III-III of Fig. 1
  • Fig. 4 is one View of the guidance system.
  • the screening device shown in the drawings consists of a rotating screening drum 1, in which a fixed, non-rotating guide device 2 is arranged.
  • This fixed guide device 2 with specially shaped and preferably inclined guide elements activates the sorting process on a very short screen surface, the performance being greater than in the conventional systems.
  • the fixed guide device 2 extends - as can be seen from Fig. 3 - preferably only about half, namely the lower inner circumference of the screening drum 1, the suspension on the side member 3 being such that the guide elements 4 are not symmetrical to the vertical axis center plane 5 arranged, but in contrast are shifted in the direction of rotation 6 of the screening drum 1, so that on the upward moving side of the screening drum 1, the guide elements 4 reach higher than on the downward moving side.
  • the measure according to the invention speeds up the sorting process because the material is not only sorted out through the sieve of the rotating sieve drum 1, but is also jammed by falling back on the guide elements 4 of the guide device 2 and is lifted up by the rotating sieve drum 1, the rest again at the same sieve point can be screened.
  • the guide elements 4 or baffle bars of the guide device 2 are preferably inclined to the drum axis either to the left or to the right and form partial surfaces of one of the coaxial to the axis of the screen drum Cylinder surfaces of the sieve drum covered screw surface. This prevents jamming of the compost material and there is a continuous abundance of this material from the first to the last chamber (between two guide elements 4).
  • the sieve drum 1 determines the grain size of the sieved material.
  • the sieve drum 1 has a circumferentially closed part which is surrounded by the inlet-side bearing ring 8; the perforated part follows and at the outlet a circumferentially closed part, which is surrounded by the outlet-side bearing ring 9, is again provided.
  • the drive assembly 10 with motor and drive gear, e.g. Belt gear, and bearing wheels 11 (preferably three or more) for the drum 1 arranged.
  • On the outlet-side bearing ring 9 (preferably three or more) bearing wheels 12 for the screening drum 1 are also mounted.
  • the longitudinal beam 3 of the guide elements 4 is also fastened to the bearing rings 8, 9.
  • a material hopper 13 is used to introduce the material to be sorted, which directs the material onto the inlet-side closed drum part, which can be provided with transversely located transport strips which rotate with the sieve drum 1. These transport strips serve to pick up the material and to convey it in the direction of the sorting area (perforated drum part).
  • the screening drum 1 and the transport strips By rotating the screening drum 1 and the transport strips, the material falls into the sorting system consisting of the rotating screening drum 1 and the fixed guide device 2 and the screening or sorting process is initiated.
  • the fine parts are screened out and the coarse parts are transported to the outlet of the screening drum 1.
  • the outlet of the screening drum 1 there is an outlet channel in order to be able to deposit the waste material.
  • Foldable supports 15, 16 are preferably arranged on the bearing rings 8, 9, and the support 15 on the inlet side can be equipped as wheels with wheels 17.
  • the outlet-side support 16 is preferably adjustable in height, e.g. with the help of socket pins 18. Instead, another actuator, e.g. a crank mechanism for height adjustment may be provided. By raising or lowering the outlet-side support 16 or the outlet-side end of the drum axis, a change in the grain size is achieved, this change also being able to be carried out during the sieving and sorting process.
  • an adjustable slide in the form of a swiveling adjusting plate 19 with an adjusting mechanism or the like can be better adapted to the nature of the material to be processed. be arranged.
  • a wiper strip 20 which extends parallel to the axis of the screening drum 1 and which cleans the screen can be arranged on the longitudinal beam 3 of the guide device 1 or on the elements 4 of the guide device.
  • the holes (sieve openings) of the sieve drum can be designed depending on the given requirements (type of material, desired grain size) in terms of size and shape. It would also be possible to form different hole sizes or hole shapes on the screen drum 1 in zones.
