Technical Field

[0001] The utility model relates to the technical field of dosing devices, in particular to an automatic dosing device for mine water treatment. Background Technique

[0002] The coal mine mine water treatment station is a facility dedicated to treating coal mine mine water. Its design, construction and operation are of great significance for ensuring the safety of mine production, improving the utilization efficiency of water resources and reducing environmental pollution. The mine water treatment station usually adopts a multi-stage treatment process, including primary treatment (such as horizontal flow grit chamber), secondary treatment (such as high-density processor), tertiary treatment (such as intermediate water tank) and quaternary treatment (such as high-efficiency integrated water purifier), etc. These processes effectively remove impurities such as suspended solids, cementitious substances and coal slime sand in the mine water through coagulation sedimentation, filtration and other methods, and improve the effluent quality.

[0003] During the treatment of the treatment station, a large amount of backwashing water is required. The backwashing water volume refers to the amount of water used during the backwashing operation of the filter in the process of mine water treatment. This amount of water is usually measured in cubic meters (m 3 ) as the unit. The backwashing operation is an important link in the mine water treatment process. Its purpose is to remove the impurities and dirt accumulated by the filter during the filtration process and restore the filtration performance of the filter. During the backwashing process, a large amount of water is required to wash the filter to ensure the cleanliness inside the filter. The main reason for the large amount of backwashing is the control of the dosing amount and the unreasonable and unscientific dosing time. At present, the common dosing formula for coal mine mine water treatment is the mixed use of PAC and polyacrylamide (PAM), generally manually dosing quantitatively and regularly according to experience, and the effect is not good. Therefore, the utility model proposes an automatic dosing device for mine water treatment to solve the problems existing in the prior art. Content of the Utility Model
