A Dust Explosion Flameproof Device Based on Flow and Vibration Coupling

Abstract

The invention discloses a dust explosion explosion-proof device based on flow and vibration coupling activation, which relates to the field of dust explosion-proof technology, including a shell, which is provided with an outlet and an inlet for ventilation and dust removal; an explosion-proof component, which includes The flameproof flap installed in the shell; the connecting part, the connecting part includes a first fixed cylinder and a first connecting piece, the first fixed cylinder is fixed in the shell, and the first connecting piece can move axially on the first fixed cylinder , the first connecting piece is movably connected to the flameproof flap; and the driving part installed on the first fixed cylinder, the driving part includes a vibration sensor and a flow sensor, and under the triggering action of the vibration sensor or the flow sensor, the inside of the driving part is provided with a push The device is used to push the first connecting piece to move towards the inner wall of the casing, so that the flameproof flap closes the casing before the explosion flame comes inside the casing, effectively realizing the purpose of dust explosion disaster reduction control.

Description

technical field [0001] The invention relates to the technical field of dust explosion protection, in particular to a dust explosion explosion protection device based on flow and vibration coupling excitation. Background technique [0002] Active explosion-proof device is a dust explosion protection product commonly used by enterprises involved in powder explosion. It mainly obtains signals through dust explosion information detection devices such as flames to confirm whether a dust explosion occurs, thereby triggering the closure of the valve of the active explosion-proof device. In recent years, although the frequency of dust explosion accidents has been effectively suppressed, they still occur occasionally. The possible reason is that when the flame detection device near the flameproof device obtains the explosion signal, the response time left for the traditional active flameproof valve to close is insufficient. , the flame escaped before the valve was completely closed, ...

Problems solved by technology

Although the frequency of dust explosion disaster accidents has been effectively suppressed in recent years, they still occur occasionally. The possible reason is that when the flame detection device near the explosion-proof device obtains the explosion signal, the response time left for the traditional active explosion-proof valve to close is insufficient. , before the valve is completely closed, the flame escapes, causing the flame to spread along the pipeline to the adjacent enclosure, resulting in the occurrence of secondary dust explosion disasters
