Problems solved by technology

There is no doubt that the concentration efficiency of this kind of thickener is low due to the intermittent feeding. In addition, the pressure relief method of opening the hopper makes the concentration of the concentrated slurry limited, and it cannot directly realize the concentration treatment of high-concentration slurry. , the overall operating economy is poor

Embodiment 1

[0025] The high-efficiency operation control method of the concentrator of the present invention is realized based on structural changes to the concentrator, and the technological measures it takes are:

[0026] -Divide all the filter plates in the concentrator into multiple groups. This grouping is to divide multiple (usually less than ten) filter plates arranged continuously in the concentrator into one group, so that all the filter plates in the concentrator Correspondingly, the hopper at the bottom of the concentrator is divided into multiple groups according to the grouping of the filter plates, so that each hopper is under the corresponding filter plate group, and each material The opening and closing of the bucket can be independently controlled;

[0027] -Each filter plate group is connected with a recoil system and drain system that can be independently controlled, and the control of the recoil system and drain system of each filter plate group remains interlocked; th...

Embodiment 2

[0042] The other content of this embodiment is the same as that of Embodiment 1, except that: the multi-stage fluid guide chambers on the housing are distributed outside the housing, and the fluid ports of the filter plates matched with each segment of the fluid guide chambers respectively extend out of the housing The body is connected to the corresponding fluid guide cavity.

Embodiment 3

[0044] The high-efficiency operation control method of the concentrator of the present invention is realized based on structural changes to the concentrator, and the technological measures it takes are:

[0045] -Divide all the filter plates in the concentrator into multiple groups. This grouping is to divide multiple (usually less than ten) filter plates arranged continuously in the concentrator into one group, so that all the filter plates in the concentrator Correspondingly, the hopper at the bottom of the concentrator is divided into multiple groups according to the grouping of the filter plates, so that each hopper is under the corresponding filter plate group, and each material The opening and closing of the bucket can be independently controlled;

Abstract

The invention discloses an efficient operation control method of a thickener and the efficient thickener. The operation control method adopts the technical measures that all filter plates in the thickener are divided into a plurality of groups, each filter plate group is provided with a backflushing system and a drainage system both of which can be independently controlled, and the control over the backflushing system and drainage system of each filter plate group is kept in an interlocking state. In a continuous feeding process of the thickener, each filter plate group discharges a filtrate through the respective drainage system and carries out filter cake stripping through the respective backflushing system, wherein each filter plate group in the thickener cannot carry out backflushing action at the same time. According to the method and the thickener, the concentration efficiency of the thickener is high, the concentration of slurry can be effectively increased, and the economic performance is excellent.

Description

technical field [0001] The invention relates to a concentrator, in particular to a method for controlling the high-efficiency operation of the concentrator and the high-efficiency concentrator. Background technique [0002] The thickener is used for thickening and clarification of slurry, and it is widely used in mineral processing, metallurgy, chemical industry, coal, building materials, environmental protection and other industries. [0003] The concentrator is mainly composed of a shell, a feed system arranged on the shell, a recoil system (usually an air intake system), a liquid discharge system, a hopper and several filter plates; each filter plate has a filter cavity The hollow structure, and the filter cavity of each filter plate has a fluid port, and the filter plate is connected to the recoil system and the drainage system through the fluid port. Its operation control process is that the feeding system sends the slurry to be concentrated into the shell and is outsi...
