[0002] A dosing device is a device used to add chemicals to water treatment systems, industrial processes, or other technological processes. Its primary function is to precisely meter and control the chemical to a target medium at a specific concentration and flow rate, thereby adjusting or improving water quality, process flow, or product quality.

[0003] The conventional existing technical solutions have the following defects:

[0004] During the dosing process, due to the small size of the drug outlet, the powdered drug is easily blocked or sticks to the inner wall when discharged, thus affecting the accuracy of drug dosing, resulting in reduced drug dosing efficiency and uneven drug dosing, which in turn affects the treatment effect;

[0005] If powdered chemicals are stored in the storage tank for a long time, they will clump together and become congested during dosing, resulting in discontinuous or stopped dosing. This will directly reduce the dosing efficiency and affect the entire treatment process. Utility Model Content
