Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of explosion proof and suppression device for dust pelletizing system, by using specific physical arrangement to realize explosion arrestment back-fire relief effect, effectively stop shock wave propagation in pipeline when there is detonation or explosion in relating to organic exhaust gas, combustible dust system, and then the generation of prevention accident, simultaneously, datonation-inhibition and extinguishing chemical it is provided with in device of blast prevention, and then reach explosion arrestment and fire extinguishing dual function, there is market prospect widely popularizing of the explosion proof and suppression device for dust pelletizing system.
For solving above-mentioned technical problem, the present invention provides a kind of explosion proof and suppression device for dust pelletizing system, explosion arrestment back-fire relief for pipeline, including: datonation-inhibition parts of putting out a fire, first guide assembly, transmission component and check valve sheet, the datonation-inhibition parts of described fire extinguishing, first guide assembly, transmission component and check valve sheet are successively set on the direction away from shock wave of described pipeline, described first guide assembly includes fixed pulley, first guide card and pulley line, described transmission component includes block and weight, described pulley line connects described first guide card and connects described block via described fixed pulley, described block is arranged on the bottom of described weight for fixing described weight, described check valve sheet abuts the bottom of described weight.
In a preferred embodiment of the present invention, described first guide card is vertical with the direction of shock wave.
In a preferred embodiment of the present invention, the datonation-inhibition parts of described fire extinguishing include extinguishing chemical, Explosion suppressant one or more.
In a preferred embodiment of the present invention, work process is:
(1) when not having explosion wave, described first guide card is not hit power, and described check valve sheet is in opening,
(2) when there being explosion wave, explosion wave, at the extinguishing chemical of datonation-inhibition parts of putting out a fire described in described pipeline internal trigger or Explosion suppressant, makes fray-out of flame, simultaneously works as the effect of acceleration shock ripple exhaustion,
(3) described guide's valve block is by impulsive force, pulls described pulley line thus pulls out described block, discharges described weight, press under described weight, described check valve sheet is closed, stops explosion wave to be propagated to the rear of described check valve sheet along pipeline, final until shock wave disappears.
The invention has the beneficial effects as follows: the present invention can stop explosion wave for the explosion proof and suppression device of dust pelletizing system, explosion wave pressure itself is utilized to trigger device of blast prevention in the case of without external source, not by external source interference, reliable for effect, the explosion proof and suppression device for dust pelletizing system universal on have market prospect widely.
