Coal slime detection and dosing device for concentration tank

Abstract

The invention discloses a coal slime detection and dosing device for a concentration tank. The device comprises a PLC and a concentration tank, the PLC is electrically connected with a coal slime detection mechanism, the PLC is electrically connected with a turbidity detection mechanism, and the beneficial effects of the invention are that: the novel intelligent coal slime detection and automaticdosing system for the concentration tank is used, so that workers do not need to be on duty when the system is used, labor intensity can be effectively reduced, operation is simple, the automation degree is high during use, the detection precision and timeliness are is reliable, detection data is more representative, a flocculating agent can be added according to actual conditions during chemicaladding, chemical consumption is reduced, meanwhile, the frequency of coal slime discharged by an underflow pump can be mastered in real time through the turbidity detection mechanism, the concentration of underflow can be made to be low, and a slime water production system and a circulating water purification system are perfected.

Description

technical field [0001] The invention relates to an automatic coal slime dosing system, in particular to a thickening pool coal slime detection and dosing device, belonging to the technical field of coal slime automatic dosing systems. Background technique [0002] In the existing life, in the coal preparation process, the coal slime in the system is recovered by thickening and filtering with a thickener. The existing coal slime monitoring relies on workers to go deep into the bottom of the thickening tank through a glass steel pipe with a backstop, and then raise it to visually observe the content and settlement of the coal slime in the glass steel pipe, and finally control the amount of chemical addition. Because this operation process requires a certain amount of experience, the results measured by different workers are not uniform, and they cannot accurately play a role in guiding production. In serious cases, it will also cause production accidents such as rake pressing....

AI Technical Summary

Problems solved by technology

Because this operation process requires a certain amount of experience, the results measured by different workers are not uniform, and cannot accurately guide production. In severe cases, it may cause production accidents such as raking.

[0003] The existing device can accurately detect the slime content in the thickener and the height of the clarified water, so it cannot guide the automatic addition of chemicals in the thickening tank during the production process, and the inaccuracy and randomness of manual dosing will cause various problems in the thickening tank. The timeliness of liquid level detection is low, and the preparation and addition of flocculant are unreasonable
