High Efficiency Improved Thickener

[Introduction] New technology is adopted in high-efficiency thickener for flocculant addition, ore feeding, automatic control and internal structure. Compared with commen thickener, high efficiency improved thickener has the advantages of large production capacity, small transmission power, compact structure and small area.

[Capability] 5-1400t/d

[Application] It is suitable for mines with large capacity and low product concentration, mainly used for concentrate concentration and tailings dewatering in concentrators, and also widely used for concentration and purification of solid granular liquids in chemical industry, building materials, water source and sewage treatment industry.

[Improvement] After improvement, the treatment capacity is high, the overflow turbidity is low, and the discharge concentration is high.

Advantages

Increasing the degassing tank can eliminate the solid particles adhering to the bubbles.
The feeding pipe is located below the liquid level to prevent the gas from entering the ore.
The feeding sleeve is moved down and a feeding tray is set up. The feeding is uniform and the falling is stable, which effectively prevents the overturning phenomenon caused by the rock pressure.
Increase the inner overflow weir, make the material flow according to the regulations, prevent short-circuit phenomenon, and increase the area of sedimentation zone.
The overflow weir is serrated, which can improve the local suction phenomenon caused by the uneven overflow weir.
The traditional inner overflow weir is replaced by the outer overflow weir, which increases the settlement area.
Equipped with a slow-flow device to slow down the rising speed of material flow, make overflow water more uniform and turbidity lower.

Structure

The highly efficient improved thickener mainly consists of a circular concentrator and a rake mud scraper. The solid particles suspended in the slurry settle under the action of gravity in the concentrator, and the upper slurry becomes clarified water, which separates the solid from the liquid. The sludge deposited at the bottom of the concentrator is continuously scraped and collected by the rake mud scraper and discharged from the central outlet of the bottom of the pond, while the clarified water overflows from the upper part of the thickener.
