Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a switchable medicine dispensing water supply device. Background Art

[0002] Polyacrylamide (PAM), abbreviated as polyacrylamids, is a linear polymer and one of the most widely used water-soluble polymers. Polyacrylamide and other bio-based materials can be used as effective flocculants, thickeners, paper enhancers, and liquid drag reducers, etc. They are widely used in water treatment, papermaking, petroleum, coal, mining, geology, textiles, construction and other work sectors. Its powdered agents are very susceptible to moisture absorption and are difficult to disperse and dissolve during preparation.

[0003] The water source for preparing PAM solution in the dosing room is tap water. The municipal tap water supply pressure is unstable. The plant area is large and the water use points are widely distributed. The water pressure and water volume fluctuate greatly. Especially after entering the summer, the water supply will be cut off at irregular intervals, resulting in failure to prepare PAM solution in time for the magnetic mixing tank, which has a great impact on the process. At the same time, due to insufficient supply, the PAM dosing pump runs idle and produces cavitation, causing equipment damage and shortening the life of the stator and rotor. Utility Model Content
