Definitions

  • the invention relates to a device for classifying very fine material from continuously supplied granular solids, with a the material of a feed chute feeding the washing trough and showers for the washing liquid, consisting of an endless Support rollers and guide rollers supported conveyor belt, which on Machine frame are supported so that part of the conveyor belt arranged downstream of the feed chute and as a washing trough is provided as well as the other part of the conveyor belt below the Feed chute against the direction of flow of the feed material is arranged rising, the conveyor belt against the Flow direction of the material is driven.
  • a device for washing organic and clay-like Contaminants from continuously supplied coarse and fine-grained Solids is known (DE 38 39 666 C1), known in this Device the material directly into the via a feed chute Wash basin is abandoned. Closes against the conveying direction a calming section is attached to the washing trough, which is supposed to that gravel and sand are retained and not with the contaminants be washed out.
  • the main disadvantage of this known device is in that when feeding the material into the washing trough and thus A turbulent flow prevails in the separation bed, which causes the settling process disturbing, whereby the settling material whirled up again becomes. This does not result in a maximum separation cut, i.e. Grain size for the very fine material to be extracted of about 0.5 mm.
  • Another The disadvantage is that large amounts of process water are required are.
  • the invention has for its object a device trained in such a way that a classification of Very fine material of the smallest grain size is possible.
  • this object is achieved solved that at the end of the washing trough over the entire width and Trough that reaches the depth of the washing trough is arranged, which is filled with spherical bodies.
  • the feed chute be static or dynamic, provided with a vibration motor.
  • the spherical bodies are different Have size, weight or surface.
  • the trough in height, inclination and the longitudinal direction is adjustable.
  • the Conveyor belt in the area of the washing trough with at least one tapping roller is provided.
  • the invention has the essential advantage that by a targeted Raining the finest material from suspensions into the separating bed 0 - 4 mm can be obtained, with grain sizes of at least 80 ⁇ can be reached.
  • the process namely a sampling and then the corresponding one Control of the machine can be a uniform grain belt, i.e. Achieve grain composition.
  • Such device has an endless conveyor belt 2, which over Deflection rollers 9 runs and on guide rollers 7 or support rollers 8 is supported.
  • the guidance of the conveyor belt 2 results here, starting from an approximately medium tension pulley, one after rising part 6 to the left and one to the right directed part 5.
  • Above the conveyor belt 2 is a Feed chute 3, the flow direction 32 of the at the material feed area 11 feed material against the direction 31 of the conveyor belt 2 is directed.
  • the conveyor belt 2 forms approximately from Area of the guide roller 7 from to the part 5 downstream of the feed chute 3 a washing trough 4.
  • the arrangement of these components takes place on a machine frame 1, for example, also can be designed that it as a lateral boundary for the Conveyor belt 2 is used.
  • the conveyor belt 2 can also be a corrugated edge belt or be limited by side guides.
  • the cleaned granular solids are on the rising part 6 of the conveyor belt 2 discharged while the fine material, i.e. the fine grain and also light pollutants on the part 5 downstream the feed slide 3 are carried out.
  • a shower device 35 adjustable in pressure and position is provided, which is used for washing up.
  • the grainy carried out on part 6 Solids are collected in a dynamic dewatering device 27 dewatered, which is attached to the machine frame 1, which Material via a feed opening 28, a drainage channel 29 with Slotted screen bottom reaches a discharge opening 30.
  • the dynamic feed chute provided with a vibrating motor 12 3 has a base 10, which is initially in the material feed area 11 up to approximately above the start of the washing trough as a blind floor 19 is formed and then adjustable to this blind floor 19 Gap 20 connects.
  • the further area 21 of the bottom 10 is with a Provide perforation. This will deliberately rain the abandoned Material into the separation bed 4 allows.
  • the feed slide 3 in the material feed area 11 on an axis 33 and in the area 21 of the perforation on an axis 34 arranged height adjustable so that the inclination can be changed.
  • the slide 3 is also in Overall length and height adjustable.
  • This configuration of the feed chute 3 makes it turbulent Avoid flow when settling the material, so that very fine material at the outlet of part 5 in an order of magnitude of approximately 0 - 4 mm can be obtained.
  • This effect can essentially also be achieved in that using a conventional feed chute in the area of part 5 downstream of the feed chute 3 a water permeable Trough 15 is immersed, which is filled with spherical bodies 16 is.
  • the trough 15 extends over the entire width and Depth, the size of the balls 16 influencing the grain size separation.
  • the surface properties also have an influence and the weight of the balls 16.
  • the trough 15 is in the Height, inclination and longitudinal direction adjustable, being an adjustable Suspension 22 (Fig. 6) is provided.
  • a knock roller 13 may be arranged.
  • a separator paddle 17 is attached, which the running Split the suspension into two film streams, the upper one Current water with light pollutants and the lower current Contains water with fine grain.
  • the device is on the machine frame 1 on one side by one Pivot point 36 can be pivoted and on the other side with the help a lifting device 37. This allows an automatic Sampling with evaluation and a corresponding control Create an even grain band.
  • the separation effect can also be influenced in that the Conveyor belt surface 14 has a degree of roughness.
  • the material is fed in via an impact box or distribution box 25, where the material, for example with the aid of a pump 26 Feed slide 3 is fed.
  • the material can also be used outdoors Case are fed.
  • the feed chute 3 is a static one Slide in which a vibratory drive is not provided.
  • the conveyor belt 2 is in the area of the rising part 6 extended to improve drainage of the material carried out there by reaching in this Area a compression unit 23 is attached and continues to the conveyor belt presses a swinging suspended roller 24 on the material to be discharged has a draining effect.
