Abstract

The invention relates to an ultralow-temperature vacuum draught fan which comprises a machine base, a machine shell, a motor, a main shaft, an impeller assembly and an air inlet ring. The machine shell is fixed to the upper portion of the machine base. A cold bridge is arranged between the machine shell and the machine base. The cold bridge is prepared from a polytetrafluoroethylene material. The impeller assembly is fixed into the machine shell. One end of the impeller assembly is communicated with the air inlet ring, and the other end of the impeller assembly is connected with the motor. The motor is fixed to the machine base. The main shaft penetrates the machine shell. A sealing structure is arranged between the main shaft and the machine shell. The impeller assembly comprises a front disc, a middle disc, a rear disc, first blades, second blades and a rotating shaft. The ultralow-temperature vacuum draught fan is used for manufacturing an ultralow-temperature vacuum environment, and the temperature can be lowered to -80 DEG C or even lower.

Description

technical field [0001] The invention relates to a fan, in particular to an ultra-low temperature vacuum fan. Background technique [0002] Sometimes it is necessary to create an ultra-low temperature vacuum environment in the laboratory, which is generally achieved by using a vacuum pump, but the temperature of the vacuum environment produced by using a vacuum pump is generally about -20°C, which is far from meeting the requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an ultra-low temperature vacuum blower for the above disadvantages, which is used to create an ultra-low temperature vacuum environment, and the temperature can be as low as -80°C or lower. [0004] In order to solve the problems of the technologies described above, the technical solution of the present invention is: [0005] An ultra-low temperature vacuum fan, including a machine base, a casing, a motor, a main shaft, an impeller ass...
