AI Technical Summary
Common vertical magnetized furnace internal pressure control devices lack safety protection functions, and high-pressure gas emissions can easily impact nearby operators, posing a safety hazard.
A pressure control device for a vertical magnetized furnace was designed. The gas is introduced into a special-shaped exhaust frame through a connecting pipe. The mechanical linkage between the wind baffle and the rotating drum, as well as the friction damping effect of the rubber sleeve, slows down the flow rate of high-pressure gas. Combined with the automatic control of the PLC controller and the vacuum pump, safe pressure relief is achieved.
It effectively reduces the flow velocity of high-pressure gas in the exhaust path, ensuring the safety of the depressurization process and protecting the safety of operators.
