Zusammenfassung: | The utility model discloses a sealing fan which comprises a fan body, a driving device, a sealing transmission device, a pressurizing device, an air inlet pipe, an air outlet pipe, an air taking port and an inflation port, the air inlet end of the fan body is connected with the air inlet pipe, and the air outlet end of the fan body is connected with the air outlet pipe; the fan is connected with the driving device through the sealing transmission device; one end of the pressurizing device is connected with the gas taking opening, the other end of the pressurizing device is connected with an inflation opening pipeline on the sealing transmission device, and pressurized gas enables the sealing transmission device to form positive pressure sealing. The problem that solid substances cannot enter a sealing cavity due to air pressure is solved by pressurizing conveying medium gas, so that sealing is effectively maintained, meanwhile, the problem that due to gas leakage in the sealing cavity, even if pressurized gas |
