Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic adhesive film manufacturing, and in particular to a solid-liquid auxiliary agent stirring structure. Background Art

[0002] Photovoltaic film is a commonly used encapsulation film for solar cell modules. It can not only play the role of encapsulation and bonding in the module, but also has various functions such as insulation, light transmission, light blocking, protection, and anti-aging. In the production process of photovoltaic film, solid particles need to be fully mixed and absorbed with liquid and powder additives during the raw material mixing stage. The absorption efficiency of powder additives and solid particles is very low, and they are very dependent on liquid additives as a medium.

[0003] At present, the powder and liquid are added to the stirring and heating spray tank separately for heating, stirring and dissolving, which is conducive to the solid-liquid absorption of particles. However, a large amount of powder is added to a smaller tank instantly, which will cause the future and dissolved powder to accumulate at the bottom of the tank, which not only affects the dissolution efficiency, but also causes the pipe at the bottom of the tank to be blocked, making it impossible to spray liquid. The powder is not dissolved in time and completely, affecting product performance and causing equipment failure.

[0004] The addition of liquid additives requires personnel to hold the additive barrel with their hands. Some personnel's illegal operations will result in residual additives and incomplete addition. This is not only time-consuming and labor-intensive, but also difficult to achieve simultaneous addition of each machine, resulting in low work efficiency.

[0005] After searching, the applicant found that the Chinese patent document with publication number CN217795674U disclosed a mixer spray tank on November 15, 2022, which relates to the field of liquid mixing devices, including a tank body, a stirring assembly is provided on the tank body, and a liquid outlet pipe is provided at the bottom of the tank body. The stirring assembly includes a shaft rotatably arranged in the tank body, a stirring member arranged on the shaft rod, and a driving member for driving the shaft rod to rotate. A scraping mechanism for cleaning the inner wall of the tank body is provided on the shaft rod in the tank body, and a blowing mechanism for blowing liquid on the inner wall of the tank body is also provided on the top of the tank body.

[0006] The device cannot achieve simultaneous addition and stirring of liquid and solid additives to the photovoltaic film, and cannot solve the problem of additives clogging the pipeline during stirring. Utility Model Content
