Novel slow-flow efficient thickener

Abstract

The invention relates to a novel slow-flow efficient thickener. The novel slow-flow efficient thickener comprises a tank body, a degassing tank, a central feed blending barrel, a motor transmission device, a rake rack lifting device, a slow-flow device, an overflow weir, a rake rack, a feeding device and a vertical shaft; the vertical shaft is arranged in the middle of the tank body; the verticalshaft passes through the central feed blending barrel, the rake rack is fixed at one end of the vertical shaft, and the other end of the vertical shaft is connected with the rake rack lifting device;the rake rack lifting device is connected with the motor transmission device, and a scraper is connected on the rake rack; the degassing tank is connected with the feeding device, and the feeding device is connected with the central feed blending barrel; and the central feed blending barrel is connected with the slow-flow device, and the slow-flow device is connected with the overflow weir. Compared with the traditional thickener, the novel slow-flow efficient thickener has high processing capability and low flow turbidity, and improves the discharging concentration.

Description

technical field [0001] The invention relates to a novel slow-flow high-efficiency thickener. Background technique [0002] The thickener is mainly used for the concentration and purification of all mixed liquids containing solid materials in industries such as mineral processing, chemical industry, infrastructure construction and sewage treatment. At present, thickeners in the prior art on the market often have the problems of material blocking, overflow "jumping muddy", and low processing capacity. figure 1 It is a structural schematic diagram of a thickener in the prior art. Such as figure 1 As shown, the thickener includes a vertical shaft 19, a cylindrical tank body 11, a degassing tank 12, a central feeding mixing tube 13, a motor transmission device 14, a rake lifting device 15, an inner overflow weir 16, and a cross-shaped rake 17 and feeding device 18, described cylindrical tank body 11 is made by cement or steel plate, and the bottom of the tank body is slightly ...

AI Technical Summary

Problems solved by technology

In the prior art, the overflow weir of the thickener is welded inside the tank body, that is, the inner overflow weir. The inner overflow weir is easy to deposit and block materials, and also reduces the settlement area, resulting in slow overflow flow.
