[0002] The quality of water supplied by a water plant is not only related to the treatment process, but also affected by factors such as the addition of chemicals. In the process of tap water production, coagulation and dosing are important links in purifying water quality, but the purification process after dosing has the characteristics of complexity, time-varying and nonlinearity. With the development of society and the increasing demand for tap water quality, traditional water purification processes have faced great challenges, and deep treatment water purification processes have gradually become popular. The water supply plant is an important part of the urban water supply system. In order to ensure water quality safety and meet health standards, water needs to be disinfected. At present, the commonly used disinfection method in water supply plants is to add chemical agents, such as chlorine, sodium hypochlorite, etc. However, there are some problems with traditional dosing devices, such as waste of agents, high energy consumption, labor costs and operating errors, and inability to adapt to the conditions required by different agents.

The utility model can clean the medicine feed pipe by arranging a cleaning component to ensure that powdered medicine will not accumulate in the feed pipe, making the feed pipe more unobstructed.

[0004] In the process of realizing the utility model, the inventors found that there are at least the following problems in this technology: it is necessary to clean it after each dosing. Long-term cleaning not only wastes water resources, but also, when the cleaning is not thorough, it is easy for the powder to adhere more firmly to the drug inlet pipe, making it difficult to clean. Therefore, a drug dosing device for a water supply plant is now proposed. Utility Model Content
