Definitions

  • the invention relates to a device for separating bulk material parts of different hardness, in particular waste parts, which consists of a drum rotating around a horizontal axis and a feed plate arranged above it, from which the bulk material in a loosened form at a distance from the vertical plane passing through the drum axis the upward-moving side of the drum arrives in such a way that soft parts of the bulk material are carried along by it from the drum to the downward-moving side of the drum and hard parts on the upward-moving side of the drum fall down, with a feed device for the bulk material is provided in such a way that the bulk material hits the feed plate at a speed which is dimensioned such that the harder parts reach the drum at a greater distance from the vertical plane passing through the drum axis than the softer part as a result of stronger rebound e.
  • the object of the invention is to provide a device which brings about a much better separation of the different parts and, in particular, easily leads misguided soft parts onto the right path, for which purpose known devices require a complex series connection of several devices of the same type ( EP-B1 01 82 892).
  • an approximately radial to Drum-facing locking plate is arranged with a soft surface layer, which is provided to avoid rebounding of the soft parts.
  • the roughness is e.g. achieved in that the surface of the feed plate is provided with horizontally extending sawtooth-like ribs in cross section, so that there is a good grip with the impacting waste parts.
  • a similarly good effect is achieved if the feed plate is provided with a layer of coarse quartz sand, which can be done using a suitable adhesive.
  • the impact velocity suitable for the separation of the parts connected to one another can be achieved by appropriate choice of the drop height.
  • the feed plate can be adjusted in a known manner with regard to its inclination and its position relative to the vertical plane passing through the drum axis.
  • the locking plate provided according to the invention can also form the bottom of a box open towards the feed plate. Then garbage parts collect in it, which serve as a soft surface layer of the locking plate.
  • the locking plate can be adjusted in the circumferential and radial directions relative to the drum.
  • the separation effect can be influenced in a known manner by air currents.
  • this is preferably done in that an air flow is generated which comes from the inner edge of the locking plate or the locking box, i.e. through the gap between one of these parts and the drum shell, is directed obliquely against the feed plate.
  • the air flow keeps the softer and generally lighter parts of the waste near the feed plate more than the harder and heavier ones, so that they are also better carried upwards by the drum.
  • This effect can be further enhanced if, in the case of a cascade-shaped feed plate, the air flow is given the opportunity to pass between the partial surfaces of the feed plate on its rear side.
  • Adjustable baffles and regulating flaps can be provided to influence the direction or the strength of the air flow.
  • a drum 2 is rotatably mounted about a horizontal axis 3. It is driven in the direction of arrow 4. Its surface is slightly rough or matt, so that soft parts adhere better to it than hard parts.
  • a feed plate 5 is provided, which is directed obliquely downwards to a point on the drum circumference which is located on the ascending side of the drum at a short distance from the vertical plane passing through the drum axis.
  • the task plate 5 is mounted horizontally displaceably in the housing 1 at its upper end with a joint 6 and can be locked in its swivel positions by means of a linkage 7.
  • the feed plate 5 consists of two plates 5a and 5b arranged in a cascade to one another, which are connected to one another by means of webs 8 in such a way that a slot 9 remains free between the two plate parts 5a and 5b.
  • the housing 1 has a feed opening 12 above the feed plate 5 and two discharge openings 13 and 14 below the drum.
  • a feed device 15 is arranged above the opening 12, from which the loose material loosens in free fall through the opening 12 onto the feed plate 5a.
  • a scraper 16 is provided above the discharge opening 13 intended for the soft bulk goods parts shown in bright colors, which removes soft parts adhering to the drum surface.
  • a box 21, which is also adjustable and is open towards the dispensing plate 5, is provided, in which soft parts accumulate and thus form a soft surface layer.
  • the air flow 25 can be changed with regard to its direction and strength by guide plates 26 and adjustable control flaps 27.
  • the feed plates 5a and 5b have a very rough surface, which in the embodiment of the device shown in FIG. 2 is formed by horizontally running sawtooth-like ribs 10 in cross section and in the embodiment shown in FIG. 4 by a support layer 11 made of coarse quartz sand is.
  • the operation of the device is as follows:
  • the bulk material falling from the feed device 15 in a loosened form through the housing opening 12 hits the upper feed plate 5a at a not inconsiderable speed.
  • the rough surface 10, 11 of this feed plate causes a certain dissolution of the bulk material, in particular a separation of adhering hard and soft parts of the bulk material.
  • the different parts rebound differently depending on their consistency and reach the drum 2 at different locations from the application plate 5, the harder ones than the softer ones. If even softer parts jump too far, they are caught by the locking plate 18 or by the box 21 and passed by these at point 17 to the drum 2, from where they are still taken up over the drum.
  • the air flow 25 provided in the embodiment according to FIG. 3 has the effect that the softer and generally lighter parts are additionally retained more after their rebound.
