Abstract
The utility model relates to a mechanical defoaming device, which comprises a first impeller and a second impeller which are coaxially arranged, wherein blades extending along the radial direction are arranged on the first impeller and the second impeller; the blades on the first impeller and the second impeller are oppositely arranged; and the vertical distance between the blades on the first impeller and the blades on the second impeller is 0.5mm to 10mm. The working principle of the mechanical defoaming device is as follows: the mechanical defoaming device rotates at a high speed along with a stirring shaft in a fermentation tank; when a lot of foams produced by fermentation liquor are in contact with the mechanical defoaming device, part of big foams are broken by bulges on the rotating blades; the remaining small foams enter the space between the first impeller and the second impeller; as the distance between the two layers of blades is very small, the pressure of fluid between the two layers of blades is bigger than that in the fermentation tank; and the small foams are broken by the action of the pressure difference, and can be completely removed through repeated and drastic shearing and pressure change.
