Owing to adopt case, sealed the hindering of the tubular one -tenth of valve to explode, hinder and explode the effect and extremely showing. The utility model discloses rational in infrastructure, the design ingenious, the gas agent is used under inclosed environment, does not receive the influence of outside air quality, with low costs, the handling ease, as long as will hinder explode device installation back alright hinder and explode, need not change any part, saved the spending.
Description
One, technical field
The utility model belongs to device of blast prevention technical field, is specifically related to a kind of pipe used in mine device of blast prevention.
Two, background technology
In existing mine gas extraction amount, more than 80% belongs to goaf or adopts the gas extracted out voltage discharging area, and wherein have the gas density of the gas pumping amount of more than 70% lower than 30%, gas density blast limit scope is 5% ~ 16%, and low concentration gas all exists serious potential safety hazard in utilization and discharge process.In order to solve the problem, people adopt various means to carry out explosion arrestment to gas tube, and Main Means has stone-dust barrier, powder extinguishing agent and explosion-proof water barrier etc.
Stone-dust barrier mainly utilizes the effect being ahead of the positive pressure of shock wave that explosive flame is propagated, and is smashed by stone-dust barrier, or utilizes quick-fried wind to be thrown by stone-dust barrier, make rock dust form rock dust cloud, cause a rock dust cloud sector, thus reduce quick-fried power, confining blast ripple conducts, and reduces hazard scope, reduces injures and deaths.But it has a very large shortcoming, because underground air is moist, rock dust leaks in atmosphere cruelly, and moisture-sensitive is lumpd and loses the ability of flying upward, and weakens the effect of stamping out the flames.
Powder extinguishing agent, as Explosion suppressant, can play the effect suppressing flame, meanwhile, forms the thin film of isolated air, plays the effect stoping resume combustion.But because the reason dry powder of price is not applied widely.
Explosion-proof water barrier uses water as extinguishing agent, form the device of isolated explosive flame as isolated water curtain, isolated blast water bottle and explosion-insulating water tank etc., it is generally arranged on the device of the isolated explosive flame of composition in underworkings, under quick-fried wind action, tank is destroyed, and very fast splits, broken, water in container spills uniformly and scatters, and stops and stamps out the flames.But the moisture of fluid barrier easily evaporates, lacks, need often to wash by water, change water, the exploiting field especially large at air quantity, temperature is high, is easily mixed into mine dust in water, causes water shortage and effectively can not cut off the propagation of explosive flame.
The explosion arrestment effect of above-mentioned various explosion arrestment means is all poor, is difficult to meet real work needs, is badly in need of a kind of new type mining pipeline device of blast prevention of development.
Three, summary of the invention
The purpose of this utility model be to provide a kind of rational in infrastructure, be skillfully constructed, effectively can overcome the pipe used in mine device of blast prevention of the many deficiencies of existing explosion arrestment means.
For achieving the above object, the technical solution adopted in the utility model is: this device comprises the explosion arrestment housing that both sides are respectively air inlet port and gas outlet, be characterized in: be provided with the aerogenesis room being built-in with combustion gas agent at explosion arrestment housing upper, the top of this aerogenesis room is provided with the trigger contacted with combustion gas agent, and bottom is communicated with air inlet pipe one end; The cylinder that front end is communicated with the air inlet pipe other end, inside is provided with piston rod is provided with in explosion arrestment housing, piston rod passes from cylinder rear end and is connected with spool, this spool matches with the valve pipe inside gas outlet and is formed when they are closed and seals, and is provided with the escape pipe led to outside explosion arrestment housing in the front side of cylinder.
During use, the utility model is connected on gas tube by inlet, outlet, and between air inlet port and gas pipe, set up venting of dust explosion parts, on the pipeline of the utility model both sides, respectively flame sensor is installed simultaneously, and flame sensor and trigger are connected with controller by wire.When gas tube burning or blast produce flame, pressure, detected Signal transmissions to controller by flame sensor, controller sends instruction makes trigger trigger combustion gas agent generation chemical reaction in aerogenesis room, and produces a large amount of gas.This large amount of gas enters cylinder by air inlet pipe from front end, and it is close to valve pipe that the piston rod promoted in cylinder outwards moves promotion spool, and last spool, valve pipe are closed forms sealing, and blocking-up flame propagation reaches explosion arrestment object.Wherein venting of dust explosion parts mainly play the effect of release pressure, flame, make flame at the rapid release pressure of gas input side, flame, thus weaken flame transmission after explosion arrestment.After explosion arrestment terminates, bled by escape pipe and piston rod is resetted, make detonation seal again open-minded.The utility model carries out explosion arrestment owing to adopting spool, valve pipe to form sealing, and explosion arrestment effect is very remarkable.Explosion arrestment process from flame being detected, pressure signal only has three phases to explosion arrestment: detection, controller, explosion arrestment, easy to operate.The utility model is rational in infrastructure, be skillfully constructed, and combustion gas agent uses under airtight environment, not by the impact of outside air quality; Cost is low, handling ease, as long as just can explosion arrestment after being installed by device of blast prevention, need not change any parts, save spending.
