Abstract

The invention discloses a bottom flow circulating system of a thickener. The bottom flow circulating system comprises a thickening pool, a bottom flow cylinder arranged at the bottom of the thickening pool, a bottom flow circulating pump and a bottom flow discharge pump, wherein the inlet I of the bottom flow circulating pump is connected with the bottom flow cylinder, the outlet I of the bottom flow circulating pump is connected with the thickening pool; and the inlet II of the bottom flow discharge pump is connected with the bottom flow cylinder and the outlet II of the bottom flow discharge pump is connected with a slurry discharging pipeline. According to the bottom flow circulating system of the thickener, through the action of the bottom flow circulating pump, ore slurry flows out from the inside of the bottom flow cylinder to the bottom flow circulating pump and flows back to the thickening pool from the bottom flow circulating pump; the process is repeated again and again, so that the ore slurry at the bottom of the thickener can be forcefully circulated and the occurrence of rake pressing or sticking of the thickener can be effectively prevented; thus the thickener with the bottom flow circulating system has both preparation and storage functions; and besides, the ore slurry of a qualified concentration can be smoothly discharged through the slurry discharging pipeline. The invention further discloses the thickener comprising the bottom flow circulating system.

Description

technical field [0001] The invention relates to the technical field of engineering material preparation technology, in particular to an underflow circulation system of a thickener. The present invention also relates to a thickener comprising the above-mentioned underflow circulation system. Background technique [0002] With the modernization of Chinese cities, buildings with reinforced concrete structures have long been common. Accompanied by this, the preparation technology of building materials is becoming more and more mature, and thickeners are needed at the head end of the technology chain. [0003] Thickener is a solid-liquid separation equipment based on gravity sedimentation, which is mainly used in mineral processing, chemical industry, coal washing, wastewater treatment and other fields. The thickener is the main equipment for thickening the pulp. It is generally used for thickening the concentrate before filtering or for tailings dehydration. The purpose is to ...
