Description

Technical Field

[0001] The utility model relates to the technical field of air flow mixers, and particularly relates to an air flow mixer with a liquid spraying function. Background Art

[0002] In recent years, air flow mixers that use compressed air as the stirring power have been developed. Because they do not need to be provided with mechanical stirring components such as blades and mixing force arms, the equipment cost is reduced, and there will be no wear and blockage problems during mixing. Therefore, air flow mixers are more popular among people.

[0003] Existing air flow mixers have some disadvantages. For example: First, directly introducing air into the mixing tank causes the introduced air to be humid, which is not conducive to the mixing of some dry powder materials, and sometimes the powder materials are also humid, making it inconvenient to dry the humid materials; Second, when mixing some powders, in order to ensure that the morphology of the mixed powders is not damaged, a liquid needs to be added during the powder mixing. Traditional air flow mixers often use the method of manual liquid addition, which is not convenient for operation and is not conducive to controlling the liquid addition measurement. Therefore, an air flow mixer with a liquid spraying function is designed. Content of the Utility Model
