Description
Technical field
The utility model relates to gas pumping pipeline tailrace, specifically is a kind of mine gas extraction pipeline gas control automatic slag-discharging water draining device.
Background technology
For preventing that coal mine gas from transfiniting and effectively utilize gas, present highly gassy mine is equipped with the gas pumping system.In the gas pumping process, because it is bigger to contain in the boring of moisture content and gas coal dust content in the coal seam, water and cinder can enter in the gas pumping pipeline, cause extraction efficient to reduce, therefore gas pumping pipeline tailrace need be installed on the gas pumping pipeline, at any time water in the extraction pipeline and cinder be discharged by gas pumping pipeline tailrace.Existing gas pumping pipeline tailrace mainly is divided into malleation and two kinds of tailraces of negative pressure, and these two kinds of tailraces all are the principles according to pressure reduction in the pipeline, utilize the rubber spherical zone to seal.With the negative pressure tailrace is example, and in the normal operating conditions, the rubber ball of ventilation and dewatering outlet is in closed condition by the negative pressure adhesive, advance the return-air mouth and open, when being raised to certain altitude, ball float is opened gas vent when waterborne, water is opened the dewatering outlet, advances the return-air mouth and closes, and realizes discharging water.This tailrace has just produced following problem owing to adopt four mouths of rubber spherical zone sealing: one, because the dewatering outlet makes progress, and ball float and slit, dewatering outlet are less, cause the cinder in the tailrace to discharge easily, cinder is piled up for a long time, and then stops up tailrace; Two, can residue in the place, mating face of rubber ball and tailrace owing to part cinder in the process that discharges water, cause easily engaging insufficient (leaving the slit) between rubber ball and the tailrace, cause gas leakage, thereby reduce extraction efficient.In sum, existing gas pumping pipeline tailrace is because self structure limits the problem of ubiquity deslagging difficulty, easy obstruction, sealing difference.Based on this, be necessary to invent the novel gas pumping pipeline tailrace of a kind of difficult obstruction and good airproof performance.
Summary of the invention
The utility model provides a kind of mine gas extraction pipeline gas control automatic slag-discharging water draining device in order to solve the problem of existing gas pumping pipeline tailrace deslagging difficulty, easy obstruction and sealing difference.
The utility model is to adopt following technical scheme to realize: mine gas extraction pipeline gas control automatic slag-discharging water draining device comprises cavity; The cavity upper side has air inlet port, return-air mouth and blow vent; The cavity bottom surface has the deslagging dewatering outlet; Be provided with the guiding push rod in the cavity; The cavity inner bottom surface is fixed with guide cylinder, and guiding push rod lower end is placed in the guide cylinder; Guiding push rod top is fixed with upper limit position block, and guiding push rod bottom is fixed with lower position block, and guiding push rod middle part is socketed with floating drum; The cavity end face is penetrated with piston rod, piston-rod lower end and guiding push rod upper end position over against; The piston rod upper end is connected with reversal valve, and reversal valve is fixed in the outer end face of cavity; Gas control ball valve (being that air inlet port, return-air mouth, blow vent, deslagging dewatering outlet all adopt the gas control ball-valve structure) all is installed on air inlet port, return-air mouth, blow vent, the deslagging dewatering outlet, is connected with the control gas circuit between each gas control ball valve and the reversal valve.Described control gas circuit is the structure that those skilled in the art realize easily.
During work, cavity is connected in the gas pumping pipeline by air inlet port and return-air mouth.When carrying out gas pumping, the gas in the gas pumping pipeline enters in the cavity by air inlet port, and water and cinder contained in the gas fall into cavity bottom, and after gas is got back in the gas pumping pipeline by the return-air mouth.Along with water in the cavity and cinder are piled up gradually, floating drum rises under the buoyancy of water and cinder gradually.When floating drum rises to the upper limit position block position of guiding push rod, floating drum promotes guiding push rod upper end and contacts with piston-rod lower end, the guiding push rod upwards promotes piston rod, piston rod drives reversal valve and commutates, and then by control gas circuit open blow vent and deslagging dewatering outlet, close air inlet port and gas outlet simultaneously, water in the cavity and cinder are discharged by the deslagging dewatering outlet thus.In deslagging discharged water process, floating drum reduced gradually along with water in the cavity and cinder and descends.When the water in the cavity and cinder drain, floating drum drops to the lower position block position of guiding push rod, this moment, floating drum promoted to break away from piston-rod lower end on the guiding push rod, piston rod resets and drives reversal valve and commutates once more, and then by control gas circuit open air inlet port and gas outlet, close blow vent and deslagging dewatering outlet simultaneously, then the gas in the gas pumping pipeline continues to enter cavity by air inlet port, water and cinder contained in the gas continue to fall into cavity bottom, finish a working cycles thus.Compare with existing gas pumping pipeline tailrace, mine gas extraction pipeline gas control automatic slag-discharging water draining device described in the utility model adopts downward deslagging dewatering outlet, prevented that cinder from piling up and the obstruction tailrace, simultaneously it is by the floating drum control deslagging process that discharges water, and has avoided discharge water gas leakage problem in the process of deslagging.In sum, mine gas extraction pipeline gas control automatic slag-discharging water draining device described in the utility model is based on brand-new operating principle, abandoned the structure that existing gas pumping pipeline tailrace utilizes the rubber spherical zone to seal, gas circuit control gas control ball-valve structure has all been adopted in its each outlet, the ball valve bore can strengthen arbitrarily as required, has thoroughly solved the problem of existing gas pumping pipeline tailrace deslagging difficulty, easy obstruction and sealing difference thus.
Further, the cavity inner bottom surface is the taper bottom surface.The taper bottom surface helps cinder is all discharged, and improves the deslagging effect.
The utility model is rational in infrastructure, designs ingeniously, efficiently solves existing gas pumping pipeline tailrace deslagging difficulty, easily stops up and the problem of sealing difference, is applicable to the gas drainage under suction in the highly gassy mine.
