Chemical adding device for coal slime sedimentation tank

Abstract

The invention discloses a chemical adding device for a coal slime sedimentation tank. The device comprises the sedimentation tank, a chemical adding port is fixedly installed on the inner wall of one side, close to the top end, of the sedimentation tank, a chemical inlet is fixedly installed on the inner wall of one side, close to the top end, of the chemical adding port, and a chemical storage box is fixedly installed at the top end of the chemical inlet. And a chemical powder self-adding device for automatically adding the chemical powder and cleaning the opening end of the chemical inlet through the gravity of the chemical powder is arranged in the chemical adding port. The function of automatically adding the chemical powder is achieved through the thrust effect converted by gravity of the chemical powder, in the process of adding the chemical powder into the sedimentation tank, the rotating effect is achieved through fixed gravity, the quantitative adding effect is achieved, and in addition, through the cooperation effect of a bearing rotating plate, a chemical receiving groove opening and the chemical inlet, when an outer ring cylinder rotates, the function of cleaning the chemical powder at the opening end of the chemical inlet is achieved, and the situation that the opening end is blocked due to chemical powder accumulation for a long time is avoided.

Description

technical field [0001] The invention relates to the technical field of coal slime treatment, in particular to a coal slime sedimentation tank dosing device. Background technique [0002] A large amount of coal slime produced in the process of coal mining and coal washing every year is a headache for people. The accumulation of a large amount of coal slime and the loss of resources not only waste precious resources, but also cause some pollution to our living environment. Coal slime flows into farmland or rivers when it encounters water, and it floats around when it encounters wind to pollute the air. It can be seen that the existing recycling technology of coal slime can turn waste into treasure, save resources, and improve the utilization rate of coal slime. Coal washing plants bring higher benefits. [0003] However, in the previous dosing device for coal slime sedimentation tank, the dosing system cannot operate normally and automatically, and the dosing process needs to...

AI Technical Summary

Problems solved by technology

[0003] However, in the previous dosing device for coal slime sedimentation tank, the dosing system cannot operate normally and automatically, and the dosing process needs to be done manually, the process is cumbersome and the efficiency is low. , the control of the amount is poor. When the amount of the drug is added, if the amount of the drug is added too much, there will be a waste of mixed powder. If the amount of the drug is added less, the phenomenon of insufficient precipitation will occur.
