Description

Technical Field

[0001] The utility model relates to the technical field of stirrers, and more specifically, to a rotary stirring device. Background Art

[0002] In the MBR process buried sewage treatment plant, most of the medicine pools are in the underground space, and the ventilation and deodorization system cannot neutralize the smell of the volatilized medicine. After observation, it was found that the reason for the serious smell of the volatilized medicine is that the traditional mixer has a single stirring action and can only perform one-way rotation stirring. The stirring efficiency is low and a higher speed is required to achieve a better stirring effect. When the stirring blade speed is too high, it will cause a large centrifugal force on the liquid medicine, causing the liquid medicine to contact with too much air, causing too much liquid medicine to volatilize, affecting the mixing of the medicine, and also causing the smell of the volatilized medicine to be more serious. The smell overflows from the medicine pool, affecting the work, and at the same time, the liquid medicine will frequently impact the wall of the medicine pool, causing the anti-corrosion coating on the inner wall of the medicine pool to fall off, affecting the service life of the medicine pool. After the anti-corrosion coating of the medicine pool falls off, it will also affect the use effect of the liquid medicine. When the stirring blade speed is too low, the stirring force will be insufficient, the liquid medicine will not be mixed sufficiently, and the use effect of the liquid medicine will be affected.
