Special-shaped inclined plane countercurrent sorting device

Abstract

The invention discloses a special-shaped inclined plane countercurrent sorting device. The special-shaped inclined plane countercurrent sorting device comprises a sorting chamber, a stirring impellerand a water distribution piece, wherein the stirring impeller and the water distribution piece are arranged in the sorting chamber; a water inlet is formed in the bottom of the sorting chamber; a feeding hole is formed in the upper part of the sorting chamber; an upward floating particle outlet is formed above the feeding hole; an opening in the upper end of the water distribution piece faces thestirring impeller, and the lower end of the water distribution piece communicates with a bottom flow hole of the sorting chamber; water distribution holes are formed in the water distribution piece; aspecial-shaped inclined plane sorting column is obliquely arranged at the upward floating particle outlet; an overflow groove is formed in an output hole of the special-shaped inclined plane sortingcolumn; a plurality of layers of inclined plates which are obliquely arranged along the axis of the special-shaped inclined plane sorting column are arranged in the special-shaped inclined plane sorting column; and the inner diameter of the special-shaped inclined plane sorting column is gradually increased from the upward floating particle outlet to the overflow groove. According to the special-shaped inclined plane countercurrent sorting device, the flowing speeds of fluids at different heights can be changed, so that the sorting precision and efficiency are improved.

Description

technical field [0001] The invention belongs to the technical field of mineral separation, in particular to a special-shaped inclined-plane countercurrent separation device. Background technique [0002] The countercurrent separation column is a new type of solid-liquid fluidized bed separation equipment with high processing capacity. It was invented by Professor Galvin of Australia in 2002 and used for coal separation. It has no moving parts, simple structure, small footprint, and low energy consumption. Low, no pollution and other advantages. [0003] Compared with the traditional fluidized bed equipment, the countercurrent separation column adds a parallel inclined plate on the upper part of the bed, so the countercurrent separation column can obtain better separation accuracy and far exceed the treatment of traditional fluidized bed equipment It can be seen that the inclined plate layer is an extremely important part of the countercurrent separation column.

Problems solved by technology

[0004] However, the traditional countercurrent separation column can only adjust the separation conditions of the separation bed and inclined plate layer by adjusting operating parameters such as ore concentration and flow rate, underflow flow rate, and ascending water flow rate. The cross-sectional area is the same everywhere, and it is impossible to carry out targeted composite physical field treatment for materials whose concentration, particle size, and object composition change due to different heights in the inclined plate layer
