Problems solved by technology

[0003] At present, the existing thickeners on the market often have problems such as material blockage, overflow, "jumping muddy", low processing capacity, and large floor space. Height, for example, the diameter can reach 100 meters, but the height is only 10 meters, so the angle of the cone bottom of the thickener is relatively large, the floor area is large and the efficiency is low

Embodiment Construction

[0022] Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0023] figure 1 It is a schematic structural diagram of a high-efficiency slurry thickening device in an exemplary embodiment of the present invention. like figure 1 As shown, the high-efficiency slurry thickening device according to the present invention includes a primary thickening chamber 10 and a secondary thickening chamber 20 arranged in series according to the slurry flow direction. Among them, the first-stage thickening chamber 10 is mainly based on the difference in specific gravity between liquid and solid and the side wall effect generated when the slurry swirls in the thickening chamber, so that the slightly thicker solid particles in the slurry settle in the first-stage thickening chamber 10, realizing a Level thickening treatment; baffles are set in the second level thickening chamber 20 to prolong the slurry flow and in...

Abstract

The invention discloses a high-efficiency thickening device and method for slurry. The device adopts two stages of thickening chambers with different thick principles and connected in series, the high-efficiency thickening of solid-liquid mixed slurry can be achieved, and the slurry thickening method is carried out by adopting the device. The thickening device disclosed by the invention is simple in structure, small in investment, small in floor area, good in continuity, low in energy consumption, stable to operate, and easy to industrialize, and a thickened material is smooth to flow, stable to operate and high in efficiency.

Description

technical field [0001] The invention relates to the technical fields of chemical industry, mining and environment, and more specifically relates to a device for thickening solid materials in a solid-liquid mixture and a thickening method thereof. Background technique [0002] The thickener is mainly used in the fields of mineral processing, chemical industry, infrastructure and sewage, etc., for the concentration and purification of all mixed slurries containing solid materials. [0003] At present, the existing thickeners on the market often have problems such as material blockage, overflow, "jumping muddy", low processing capacity, and large floor space. The height, for example, the diameter can reach 100 meters, but the height is only 10 meters, so the angle of the cone bottom of the thickener is relatively large, the floor area is large and the efficiency is low. [0004] Therefore, it is necessary to provide a thickening device capable of realizing the separation of so...
