Description

Technical Field

[0001] The utility model relates to the field of sewage treatment, in particular to an automatic drug dissolving device integrating pneumatic conveying and stirring. Background Art

[0002] In the sewage treatment process, it is often necessary to add a variety of chemical agents. For the dissolution of powdered agents, a stirring paddle dissolution equipment is generally used. The agent addition method is generally manual addition, gravity addition or mechanical screw conveying.

[0003] Manual addition of reagents requires a lot of work and is prone to dust pollution. Gravity addition and mechanical screw conveying are not suitable for long-distance transportation of reagents and are prone to clogging pipelines, causing equipment failure. Paddle-type dissolution equipment relies on a paddle to stir the solid-liquid mixture to dissolve the reagent. The paddle is subject to the risk of corrosion, breakage, and jamming, and the mixing effect is poor.

[0004] Therefore, an automatic drug dissolving device with pneumatic conveying and stirring is provided to solve the above problems. Utility Model Content
