Problems solved by technology

The existing feeding system of the thickener generally has the following deficiencies: first, the contact probability between the slurry and the flocculant is small, the mixing is uneven, and the effect of laminar flow settlement cannot be formed, and the slurry enters from the center of the thickener, which cannot reach the expected level.

Abstract

The invention relates to a feeding system for a thickener. The feeding system comprises a feeding pipe, a flow stabilizing cylinder, a flocculant pipe, a distributing ring and a scraper, wherein the flow stabilizing cylinder comprises a main material cylinder, a deflector, a grading blade and a diluting pipe; an outlet of the feeding pipe is communicated with an inlet of the main material cylinder, the deflector is arranged on the inner side of the main material cylinder, the grading blade is arranged on the inner side of the deflector, the diluting pipe is communicated with the main material cylinder in the tangent direction of the main material cylinder, the flocculant pipe is arranged above the deflector and is communicated with the deflector through a flocculant hopper, the distributing ring is arranged below the main material cylinder, and the scraper is arranged above the distributing ring. Through the feeding system for the thickener, the sedimentation efficiency of the thickener can be effectively increased, the sedimentation speed is increased, and the processing quantity of unit area of a thickening pool is increased.

Description

technical field [0001] The invention relates to a thickener, in particular to a feed system of the thickener. Background technique [0002] At present, there is a strong demand for thickeners in industries such as mine dressing, tailings treatment, and sewage treatment, among which high-efficiency thickeners account for the vast majority of the industry. The so-called high-efficiency thickener is mainly reflected in two aspects. First, the flocculant addition method. A large number of tests and field conditions have proved that the flocculant has unique advantages in laminar flow settlement, which can make fine particles form flocs and speed up the process. Settling speed; secondly, the thickener runs continuously for a long time, and basically does not need to be shut down for maintenance. These two aspects can greatly improve the processing capacity of the thickener. The existing feeding system of the thickener generally has the following deficiencies: first, the contact...
