Background

At present, the domestic high-efficiency thickeners which are widely applied mainly have three types: 1. a central transmission and central rake lifting thickener; 2. a peripheral transmission and sectional rake-lifting thickener; 3. a peripheral transmission central rake-lifting thickener; the third type, the central transmission and central rake-lifting thickener, is advanced, and integrates the advantages of the first two thickeners.

However, because the material in the bottom of the concentration tank near the central part is deposited more than the material in the peripheral part; and the materials deposited on the peripheral part are scraped towards the center, so that the scraping efficiency of the central part of the concentrator is required to be higher than that of the peripheral part, and the scraping times of the concentrating tank bottom close to the central part and the peripheral part are the same every revolution of all the concentrators at present. Therefore, if the scraping requirement of the peripheral part is only met, the rotating speed of the rake frame is low, the scraping requirement of the central part cannot be met, and rake pressing is easily caused; if the scraping and collecting requirements of the central part are met, the rotating speed of the rake frame is high and exceeds the requirements of the peripheral part, energy waste is caused, the rotating linear speed of the rake frame of the peripheral part is high, materials are prone to being shaken, and unfavorable material precipitation is caused. This problem is particularly acute in large concentrators. Moreover, most of the existing mud scrapers under the thickener are fixed in the same direction and cannot be turned over, and when the thickener rotates in one direction for a long time, the mud scrapers are easy to scrape unclean.

An effective solution to the problems in the related art has not been proposed yet.
