Description
Technical field
The present invention relates to underground coal mine protector, be specially a kind of gas drainage under suction protector.
Background technology
Underground coal mine should set up gas drainage system according to " safety regulations in coal mine " and " " one through three prevention " secure quality standardizatio standard " requirement, but extraction circumstance complication, in extraction pipeline, gas density is high, a large amount of dry coal dusts is easily blown in pipeline, electrostatic is produced by rubbing with inner-walls of duct, bring out gas combustion in pipeline, cause section of tubing to burst, cause the gas drainage pipeline in tunnel to burst.
Summary of the invention
The present invention produces to solve existing gas drainage pipe Louis the problem that electrostatic explosion exists potential safety hazard, provides a kind of gas drainage under suction protector.
The present invention adopts following technical scheme to realize: gas drainage under suction protector, comprise extraction pipeline, extraction pipeline front portion is provided with the emptying threeway that two ends are communicated with it, and the 3rd end of emptying threeway is provided with exhaust-valve, and emptying threeway is provided with plugging valve with the one end be communicated with on front side of extraction pipeline; Extraction pipeline is arranged at intervals with some metallic ground pole pipe, two ends and the extraction pipeline of metallic ground pole pipe pass through Flange joint; Extraction pipeline arranges jettison gear, jettison gear comprises cylindrical shell, cylinder lateral wall top is provided with the water inlet pipe with extraction pipeline communication, and water inlet pipe is provided with water intaking valve, and cylinder top is provided with breather valve and negative-pressure balancing pipe, cylinder lateral wall bottom is provided with gutter, gutter is provided with draining valve, and in cylindrical shell, bottom center is fixed with guide holder, and guide holder upper end is fixed with magnet, be provided with the iron block attracting with it above magnet, it is cursory to be fixed with above iron block.
After gas drainage under suction, when termination of pumping, first open exhaust-valve, suck fresh distinguished and admirable from exhaust-valve, close plugging valve simultaneously, stop the gas sucking goaf, after the gas density of gas drainage under suction chamber drops to 0%, closed gas drainage pump, by arranging metallic ground pole pipe, the electrostatic produced being imported underground, eliminate the threat of electrostatic to gas drainage system with this in gas drainage under suction process, during gas drainage under suction operation, negative-pressure balancing pipe and water intaking valve are opened, under the effect of gas drainage pipeline negative pressure, draining valve is in closed condition, now the water of gas drainage pipeline flows in cylindrical shell by water inlet pipe, cursory will rising along with water level and depart from magnet rise, water intaking valve and negative-pressure balancing pipe are closed, breather valve is opened, under the acting by external hydrostatic pressure of ponding, draining valve is opened, start to discharge water, along with continuously outflowing of water, cursory decline, negative-pressure balancing pipe and water intaking valve are opened, breather valve and draining valve are closed under atmospheric pressure effect, again be communicated with gas drainage pipeline, cursory position is in original state again, so go round and begin again and realize automatic draining, overcome existing gas drainage pipe Louis and produce the problem that electrostatic explosion exists potential safety hazard.
Reasonable in design of the present invention is reliable, make gas drainage under suction work normally can carry out extraction work, thus ensure that mine safety production, and ensured gas suction pump exempt from damage, effectively save cost payout, and there is structure advantage simple, easy to process.
