Mechanical-electrical integrated explosion-proof device

Abstract

The invention discloses a mechanical-electrical integrated explosion-proof device. The mechanical-electrical integrated explosion-proof device comprises a pressure vessel, a pressure control valve, a control loop, a rotary shaft, a sealing cover and a motor. The pressure control valve, a groove, an explosion-proof exhaust port, the rotary shaft, the sealing cover and the motor are arranged on the upper portion of the pressure vessel. A pressure relief hole, a piston block, a spring, a conducting strip, a first wire, a conductive cylinder and a second wire arranged on the pressure control valve. The control loop is arranged at the lower end of the first wire and the lower end of the second wire in a connected mode. A power source, a resistor and a controller which are sequentially connected through a wire are arranged in the control loop. According to the mechanical-electrical integrated explosion-proof device, the pressure is controlled flexibly through cooperation of the pressure relief hole and the piston block provided with the spring, and meanwhile, the control loop is additionally arranged to control the motor to drive the sealing cover to rotate, so that it is guaranteed that a pressure relief measure is additionally taken in time to avoid an explosion when the pressure is too high.

Description

technical field [0001] The invention relates to an explosion-proof device, in particular to an explosion-proof device integrated with machinery and electronics. Background technique [0002] Pressure vessels generally refer to containers used in industrial production to complete production processes such as reaction, heat transfer, mass transfer, separation, storage and transportation, and to withstand a certain pressure. Such as reaction vessels, heat exchange vessels, separation vessels and storage and transportation vessels. Due to the various needs of the production process, there are many types of pressure vessels, and the specific structures are also various. But their common feature is that they all have a shell of various shapes that can withstand a certain pressure. my country's "Interim Regulations on Boiler and Pressure Vessel Safety Supervision" defines pressure vessels as "various pressure vessels with a pressure above one gauge pressure". It is also clearly ...

AI Technical Summary

Problems solved by technology

[0003] At present, the explosion incidents of pressure vessels are frequently seen in the newspapers, but there is no good way to control the explosion of pressure vessels. Most of them use pressure gauges to observe and avoid explosions through pressure gauge monitoring. However, this method is not suitable for sudden The response speed of the pressure increase problem is not enough; now, for the explosion-proof problem of the pressure vessel, a device that can solve the explosion and effectively control the danger during the formation process is needed, which can reduce expenditure and avoid hidden dangers
