Paste thickener aggregate well stirring device

Abstract

The invention provides a paste thickener aggregate well stirring device, belonging to the technical field of paste stirring devices. The device is formed by welding angle steel, I-shaped steel, steel pipes, flanges and a sealing plate according to a certain angle and arrangement mode. The I-shaped steel is vertically welded on a driving shaft; the angle steel is welded at the end part of the I-shaped steel and is parallel to the driving shaft; the difference of every two of the four welded stirring arms is 90 degrees; the driving shaft is formed by processing the steel pipes; the top end of the driving shaft is connected with a rake rack on the upper part by virtue of a flange; the part which is 50mm away from the bottom of the driving shaft is sealed by the sealing plate; the bottom of the driving shaft is inserted into a wear-resistant steel pipe; the height of the driving shaft changes between 1500mm and 2500mm. The device disclosed by the invention is simple and reliable, the problems that the traditional aggregate well stirring device is unreasonable in structure and the stirring device is easy to degenerate, warp and drop can be effectively solved, the problems that the underflow concentration in the paste thickener aggregate well is not homogenized and the paste thickener presses the rake and stops and the like are further solved, and slurry homogenizing and fluidization stirring of the paste thickener aggregate well are realized.

Description

technical field [0001] The invention relates to the technical field of a paste stirring device, in particular to a paste thickener collecting well stirring device. Background technique [0002] After the ore mined from the mine is processed, the remaining solid waste is called tailings, which are generally discharged in the state of low-concentration tailings slurry. The discharge of low-concentration tailings often causes many problems such as environmental pollution, waste of water resources, and dam failure of tailings ponds. Therefore, the whole tailings paste technology has emerged as the times require. The paste thickener can thicken low-concentration tailings into a high-concentration full-tailing paste with low moisture content at one time through flocculation and sedimentation, which solves the problem of traditional low-concentration tailings discharge. [0003] The aggregate well is the core structure of the paste thickener. After thickening and dehydration, the ...

AI Technical Summary

Problems solved by technology

If the high-concentration tailings slurry in the aggregate well is not stirred effectively in time to form a homogenized and fluidized full-tailings paste, it is very easy to cause accidents such as the shutdown of the thickener rake and the inability to discharge the underflow.

[0004] However, due to the unreasonable structural design of the traditional aggregate well mixing device, it cannot effectively stir the whole tailings paste. When subjected to large shear resistance, the stirring device often deforms, twists, and falls off, causing the paste thickener shutdown
