Description

Technical Field

[0001] The utility model relates to the technical field of mixing and stirring, in particular to a mixing and stirring machine. Background Art

[0002] Aqueous film-forming foam fire extinguishing agent (AFFF) has the ability to spontaneously spread on the surface of oil to form a dense water film, hence its name. The formed water film can not only cool the fuel surface, but also isolate oxygen, hinder fuel evaporation and other mechanisms to extinguish fires. It is considered to be one of the most effective fire extinguishing agents for extinguishing oil fires. The key ingredient that allows this type of foam fire extinguishing agent to spread spontaneously is fluorosurfactant, which has extremely strong surface activity and can cause the foam liquid to spread spontaneously under the drive of surface / interfacial tension. As PFOS produced in the production process of fluorosurfactants was found to be toxic and difficult to degrade, when producing foam fire extinguishing agents, it is necessary to mix surfactants, oil phases and carrier auxiliary materials to form an emulsion preparation. Existing mixing mixers are mostly single-axis, and the mixing effect is not high. When the single-axis rotates and stirs, it is easy to form a regular vortex-like fluid, resulting in poor relative fluidity inside the material, making the stirring efficiency low.
