High-pressure fan for vulcanizing tank

Abstract

The invention discloses a high-pressure fan for a vulcanizing tank. The high-pressure fan comprises a motor and fan blades, and is characterized in that the motor is connected with a vulcanizing tank body in a sealing manner by virtue of a flange, the fan blades are installed on a motor shaft stretching into the vulcanizing tank body, a condensation pipe is installed on the right end surface of the motor, the front end of the condensation pipe penetrates through the flange to be communicated with the vulcanizing tank body and provided with an air inlet, the condensation pipe, which is disposed on the bottom of the right end surface of the motor, is connected with a drain tee, the right end of the drain tee is connected with the condensation pipe in a sealing manner, an air returning opening is formed in the upper end of the drain tee, a water outlet is formed in the bottom end of the drain tee, the bottom end of the water outlet is provided with a backflow pipe communicated with the vulcanizing tank body, and the backflow pipe is provided with a single-directional drain valve. The high-pressure fan for the vulcanizing tank has the following beneficial effects: water vapor can be effectively prevented from entering the motor, the service life of the motor is prolonged, and the production cost is reduced. The condensed water can flow back to the vulcanizing tank by virtue of the backflow pipe, so that the water resource is saved.

Description

technical field [0001] The invention relates to a fan, in particular to a high-pressure fan for a vulcanization tank. Background technique [0002] The traditional vulcanization tank fan is connected to the vulcanization tank body through a flange. Since the high-pressure steam in the vulcanization tank body gradually penetrates into the motor through the mechanical seal of the motor, it will seriously affect the life of the motor after condensing into water. The main reason for the infiltration of water vapor into the motor is that the pressure difference between the autoclave body and the motor is caused by the pressure difference, which causes the water vapor in the autoclave body with high pressure to gradually infiltrate into the motor with low pressure. At the same time, due to the consumption of water vapor at the outlet of the motor, the water in the vulcanization tank body is gradually reduced. If the vulcanization work is continued, more water needs to be added, wh...

AI Technical Summary

Problems solved by technology

At the same time, due to the consumption of water vapor at the outlet of the motor, the water in the vulcanization tank body gradually decreases. If the vulcanization work continues, more water needs to be added, which will lead to waste of water resources.
