Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and more specifically, to a dosing device for sewage treatment. Background Art

[0002] The sewage treatment dosing device is a device specially used for treating sewage. Its core is to remove pollutants and improve water quality by adding specific chemicals to react chemically or physically with harmful substances in sewage. This device is widely used in the fields of drinking water, urban sewage and industrial wastewater treatment. The type of added chemicals varies with the treatment process. Existing sewage treatment dosing devices often use the method of directly pouring the chemicals into the mixing tank, which has obvious disadvantages. Since the drug cannot dissolve quickly inside the mixing tank, the mixing process of the drug and sewage becomes slow and the stirring time is too long, which not only affects the efficiency of sewage treatment, but also may affect the treatment effect due to uneven distribution of the drug. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a drug adding device for sewage treatment, which has the advantage of uniformly stirring drugs.

[0004] To achieve the above object, the utility model provides the following technical solution: a dosing device for sewage treatment, comprising a workbench, a support frame is fixedly installed on the top of the workbench, a second stirring box is fixedly installed on the top of the support frame, and a drug inlet is fixedly installed on the top of the second stirring box;

The one-way valve 28 allows the drug to slowly enter the interior of the mixing box 2 through the drug inlet pipe 13. Compared with the traditional device, the device ensures the uniform distribution of the drug in the liquid through the cooperation between the rotating shaft 27 and the dragon 26, improves the dosing effect, and enables the drug to fully demonstrate its efficacy. At the same time, pre-mixing reduces the mixing time and intensity in the mixing box 2, improves the mixing efficiency, reduces energy consumption, reduces equipment wear and maintenance costs, and extends the life of the equipment.
