Definitions

  • the invention relates to a device for washing out organic and clay-like impurities from continuously supplied coarse and fine-grained solids, such as freshly dredged and processed gravel, with a chute and shower for the washing liquid which feed the material, consisting of an endless conveyor belt supported on support rollers , which are mounted on the machine frame in such a way that part of the conveyor belt is arranged downstream of the chute and is provided as a washing trough, and the other part of the conveyor belt is arranged below the chute and rising upward against the direction of flow of the material fed, the conveyor belt counter to the direction of flow of the the chute is fed material (see FR-A-2 325 433).
  • Such a device is known (DE-PS-2 263 549), in which the parts of the conveyor belt are held on frame parts which can be pivoted about a common support bearing, and a belt is also used as the conveyor belt which has upstanding edges on its sides has, or is designed as a corrugated edge belt.
  • a smooth belt is used as the conveyor belt, which is arranged on the two end edges between close-fitting housing side parts. The water and impurities are discharged through a funnel located below the housing. The cleaned coarse material such as sand, ore, coal bauxite and the like is transported out of the housing and processed against the direction in which the impurities are conveyed.
  • This coarse material is provided with a small amount of water, so that it is usually necessary to carry out post-drainage, for which special additional drainage apparatuses are necessary, which cause considerable effort and energy. In addition, there are losses in the discharged material during this dewatering process.
  • the invention has for its object to improve a device of the type mentioned in that post-drainage of the discharged cleaned coarse material is avoided.
  • vibration compressors are arranged in the region of the rising part of the conveyor belt running below the chute and outside the washing trough, the conveyor belt being supported from below by the vibration element.
  • the vibration element advantageously extends over the entire width of the conveyor belt.
  • vibration element is adjustable vertically to the conveyor belt and in the running direction of the conveyor belt.
  • the excitation frequency of the vibration compressor be adjustable.
  • the invention has the essential advantage that complete measures can be used to completely dewater the cleaned coarse material, so that subsequent dewatering is avoided using complex equipment. Only a small amount of energy is still required for the use of the additional device, and wear is still extremely low.
  • the device can also be adapted with simple means to the special features of the known device, such as inclination of the conveyor belt, pressure and the like.
  • the device shown in Figures 1 and 2 has a machine frame 1, which is composed of individual carriers 2, 26 which are provided with an inner lining to form a container 27 with an outlet funnel 28. On the individual carriers 2, 26, pressure or deflection rollers are held, around which a conveyor belt 29 is guided.
  • the upper part of the conveyor belt 29 is used for the actual washing-out process, a part 9 of the conveyor belt 29 arranged downstream of the chute 12 forming the actual washing trough 30 and a further part 11 of the conveyor belt 29 below the chute 12 against the direction of flow of the chute 12 Material is arranged increasing.
  • the shape of the washing trough 30 is essentially formed by the height-adjustable pressure roller 18 arranged in the center on the carrier 2, the roller 6 and a support roller 17.
  • part 9 of the conveyor belt 29 In the area of part 9 of the conveyor belt 29, this is guided on the outside via a further deflection roller 32 which also serves as a tensioning roller, a horizontally extending part 33 of the conveyor belt 29 being provided between the rollers 6 and 32.
  • the opposite part 11 of the conveyor belt 29 is guided at the uppermost point via a drive roller 7 with a drive motor 34. wherein the roller 7 is adjustable in height with the aid of washers 35.
  • Below the tensioning roller 18, the conveyor belt is guided over a deflection roller 31.
  • vibration compressor 40 In the area of the rising part 11 of the conveyor belt 29, outside the washing trough 30, there is a vibration compressor 40 which extends over the entire width of the conveyor belt 29 enough.
  • This vibration compressor 40 has an anchoring plate 41, which is attached to the machine frame 1 of the device and to which oscillating elements 42 are attached, which in turn carry a pressure plate 43.
  • the vibrations of the pressure plate 43 are generated by a mechanical or electrical exciter 44.
  • the plate 43 rests under pressure on the conveyor belt part 11, there being various possibilities for changing the position of the plate 43 and also the intensity of the vibration compressor 40.
  • slots 45 can be provided on the anchoring plate 41 so that the inclination of the plate 43, the distance to the conveyor belt part 11 and also the height, that is to say the distance to the washing trough 30, can be changed.
  • a further adjustment possibility results from the excitation frequency for the exciter 44.
  • a roller can also be used, which also extends over the entire width of the conveyor belt part 11, the use.
  • a plate 43 or such a roll depends on the material to be processed. Depending on the material and the water content, it may be necessary to provide several such vibration compressors 40.
