Efficient thickener

Abstract

The invention discloses an efficient thickener. The efficient thickener comprises a bracket, a thickening cylinder, a bottom flow cone, a stirring device, a defoaming box, a feeding cone, a scraper, aliquid level monitoring device, an overflow hole dirt removal device and a PLC control system; and the feeding cone is arranged on the upper part of the bottom flow cone, a distribution cone providedwith the small upper part and the large lower part overall is arranged at the bottom of the feeding cone, a dispersion flow channel used for dispersing flocculate to the periphery of the thickening cylinder is formed between the lower edge of the distribution cone and the lower edge of the feeding cone, and a feeding inlet of the feeding cone communicates with a discharging outlet of the defoaming box through a connecting pipe. The efficient thickener is convenient to control, a discharging opening is not prone to being plugged by thick ore pulp in the discharging process, the work efficiencyof the thickener is effectively improved, and great convenience is brought to the mineral separation work of the thickener.

Description

technical field [0001] The invention relates to the technical field of solid-liquid separation equipment, in particular to a high-efficiency thickener. Background technique [0002] Thickener is a kind of solid-liquid separation equipment based on gravity sedimentation. After mixing the pulp and flocculant, it is transported into the thickening cylinder. The sediment layer, and settles to the bottom of the dense cylinder, and the liquid rises through the sediment layer, and the sediment layer acts as a filter, so that fine particles cannot rise; the slurry moves in the sediment layer, so that the particles and flocculation flocculation continues to occur; the drive motor drives the scraper set at the lower part of the stirring shaft to rotate, pushing the dense pulp to the discharge port at the bottom of the dense cylinder, and finally discharged through the discharge port and filtered out through the sediment layer. The liquid is finally discharged through the overflow hol...

AI Technical Summary

Problems solved by technology

[0003] The overall structure of the thickener in the prior art is relatively complicated, and the operation is relatively cumbersome. The thickener with this structure not only improves the labor intensity of the operator, but also improves the overall production cost of the thickener; another, the existing thickener During operation, the thicker pulp deposited at the bottom of the thickening cylinder is very easy to block the discharge port during the discharge process, and the thickener with the blockage of the discharge port cannot work normally, and the operator needs to stop the treatment before restarting Thickener, using this method seriously reduces the working efficiency of the thickener and brings great inconvenience to the beneficiation work of the thickener
