The invention relates to a back flushing type self-cleaning dosing tank chemical supply device and a chemical supply method thereof, which belong to the technical field of water treatment equipment inthe metallurgical industry. The technical scheme is characterized in that one end of a dosing pipeline (11) is connected to a dosing tank (9), the other end of the dosing pipeline (11) is connected to the inlet of a dosing pump (6), one end of a back flushing pipeline (4) is connected to the outlet of the dosing pump (6), the other end of the back flushing pipeline (4) is connected to the dosingtank (9), a back flushing valve (3) is arranged on the back flushing pipeline (4), a chemical supply pipeline (1) is connected to the back flushing pipeline (4), a chemical supply pipeline valve (2) is arranged on the chemical supply pipeline, a blowdown pipeline (8) is connected to the dosing pipeline (11), a blowdown valve (7) is arranged on the blowdown pipeline (8), and a dosing pump motor (5)is in driving connection with the dosing pump. The advantages of the invention are as follows: chemical sedimentation after a long time of chemical storage can be prevented, and the problem that thedosing pump cannot supply chemical due to blockage by chemical impurities is solved.
Description
technical field [0001] The invention relates to a backwash type self-cleaning medicine feeding tank medicine supply device and a medicine supply method thereof, belonging to the technical field of water treatment equipment in the metallurgical industry. Background technique [0002] At present, the chemical supply device of the chemical dosing tank is widely used in the field of water treatment in the metallurgical industry. Because the medicinal liquid is viscous and easy to precipitate, and contains a lot of impurities, it often causes the dosing pump to be blocked, and the medicine cannot be supplied normally, and the composition of the medicinal liquid is uneven, which affects the efficacy of the medicine. Contents of the invention [0003] The purpose of the present invention is to provide a backwash type self-cleaning drug supply device for the drug feeding tank and its drug supply method, which can self-clean the drug feeding tank, avoid the precipitation of the dru...
