    A system for subjecting a slurry containing solids and a liquid and a flocculating agent in a processing chamber to forces to move the slurry, liquid and flocculating agent through the processing chamber from an inlet opening to an outlet opening in turbulent flow along a continuous spiral and circulatory path so as to form the solids into floccules which may be readily separated from the liquid in which they are contained.

    专利说明:

    The invention relates to a device for separating solid particles from liquids, including the use of flocculating agents, such as polymers, and more specifically for separating solid fine-grained particles, ranging in size from about 28 mesh to zero, from fluids, such as waste from a coal preparation plant.
    The purpose of the invention is to increase the separation efficiency.
    FIG. 1 is a diagram of the technological process of a coal preparation plant; in fig. 2 - the proposed device, side view; on. FIG. 3 - the same, top view.
    The process plan of the coal preparation plant includes a conveyor 1, moving the ore and dumping it to the desliming sieve 2, where it is divided into parts larger than 28 mesh and particles from 28 mesh to zero. A material larger than 28 mesh is fed to the sediment machine 3, which uses water to separate low ash

    coal from waste, such as stone, slate and high ash material to be removed. The separation is carried out by ps specific gravity, with the coal floating on the surface of the sediment machine 3, and the waste going to the bottom. Low-ash coal is separated and supplied to the dewatering screens 4, and then to the trolley 5. The waste is removed from the sediment machine 3 by the conveyor 6 and transported to the conveyor 7. where it is discharged into the loading bin 8. The ore size is from 28 mesh to 32321HF
    It began to filter wastes with industrial debris about 15–20 t / h. ;; This is essential because if the filter device 11 in some cases cannot precipitate solids in a thickener, it should work after shifts. This means that there are no coarse bends on conveyor 7, so that waste sizes from 23 га. Ha to zero cannot be moved with coarse waste and must go to landfill 15 alone, which is undesirable. In addition, the pressed precipitate filter 10

    l is supplied to flotation cells 9, 15 The properties are relatively hard and dry, where low-ash coal from 28 mesh to zero is separated and fed to the filter unit 10. Water and fine material are drained from the dewatering screen 4 and also fed to the flotation cells 9. Dehydrated low-ash coal from 28 mesh to zero is transferred from the filtering device to the trolley 6. Waste from 28 mesh to 25 zero is lowered to the bottom of the flotation cells 9 and transferred as a suspension to a device for separating solids from the seals 11. Condensed wastes ranging in size from 28 mesh to zero 30 are fed as a slurry into a forming agent 12, where a flocculating agent is introduced into the slurry, which is then subjected to a turbulent flow so that the waste from 28 mesh to zero forms flakes in the slurry, and is fed to the waste filter 13.
