Vertical foam generator

The present invention discloses a vertical foam generator, which comprises a body, a sealing assembly, a diversion shield and a cover plate, wherein the body and the sealing assembly form a sealed connection through a bolt assembly and a plate pressing sealing ring, the diversion shield and the body form a sealed connection through a connection flange assembly, and the cover plate and a cover sealing ring form a sealed connection through a bolt assembly. The vertical foam generator is characterized in that the sealing assembly of the vertical foam generator is provided with a blasting sheet, the blasting sheet is arranged into the metal diaphragm, the thickness of the metal diaphragm is 0.01-0.02 mm, the blasting value of the metal diaphragm is 0.1-0.3 MPa, the materials of the plate pressing sealing ring and the cover sealing ring are the high temperature resistance rubber materials, and the suitable environment temperature of the high temperature resistance rubber material is 200 DEG C. According to the invention, with the optimized design on the blasting sheet and the sealing ring, the error blasting phenomenon of the air foam generator during the moving, transportation and installation processes can not occur, and the air foam generator can be stored and used under the environment with the temperature of 200 DEG C.
