Description
Technical field
This utility model belongs to coal mine gas exhaust technology field, is specifically related to a kind of gas drainage pipeline negative pressure automatic slag-discharging water draining device.
Background technology
Gas drainage under suction is the primary major issue in high methane colliery.But coal mining geology is complicated, gas drainage pipeline is straggly along with physical features height, after in coal seam, moisture enters pipeline with gas, the dregs such as moisture and ickings will accumulate in the low-lying place of pipeline, pipeline blockage, have a strong impact on gas drainage under suction efficiency, cause great potential safety hazard.
Current deslagging discharges water and mainly has two ways: one is to use artificial drainage, slag discharge, it is come manual periodic exhaustion water and waste residue by people, inefficient, anthropic factor impact is bigger, often discharge is not in time, and coal ash and slag discharge be not clean, needs people manually to remove, is greatly increased labor intensity and workload；Two is to use automatic slag-discharging water draining equipment, Vehicles Collected from Market all of automatic slag-discharging water draining equipment, due to unreasonable structure, just can not work in the case of the negative pressure of gas pipeline is slightly larger, common automatic slag-discharging water draining equipment normally can only work in the case of minimum in negative pressure (blower pressure of below 0.04Mpa), once negative pressure exceedes above-mentioned pressure, can not work at all, actual gas pipeline working environment needs can not be met far away, and existing automatic slag-discharging water draining equipment have can not deslagging, some weak effects getting rid of sediment, dregs precipitation causes equipment not work.
Utility model content
In order to overcome the problem of background technology, this utility model provides a kind of gas drainage pipeline negative pressure automatic slag-discharging water draining device, and this utility model volume is little, lightweight, and can discharge water under bigger negative pressure condition, and deslagging performance is good.
This utility model solves its technical problem and be the technical scheme is that
A kind of gas drainage pipeline negative pressure automatic slag-discharging water draining device, including storage tank, storage tank top is provided with water storage case lid, and storage tank is provided with water inlet and air inlet, is provided with on dewatering outlet, water inlet and dewatering outlet and is provided with valve gap bottom storage tank；Described storage tank is internally installed ball-cock assembly；Described ball-cock assembly includes valve body, and valve outer surface upper end is fixing connects magnet steel, and valve inner is provided with through hole；Through-hole side wall connection malleation mouth, negative pressure mouth and interior accent, through hole is internal by installing set slip cap cartridge control valve core；Described malleation mouth connects air inlet by pipeline, and described negative pressure mouth connects water inlet, described interior accent connection storage tank by pipeline；Described control spool top is fixing connects magnet steel, controls spool and forms venting cavity with through hole, controls spool bottom socket litter；Described litter is installed with locating piece and lower locating piece, and litter is slidably socketed slide block；Slide between described slide block and lower locating piece suit ball float.Gas drainage pipeline is connected with water inlet, and owing to the negative pressure in gas drainage pipeline is by negative pressure mouth and venting cavity, then by interior accent and the air communication in storage tank, whole storage tank is internal is negative pressure.The valve gap of dewatering outlet is automatically switched off due to pressure differential, and the valve gap of water inlet automatically opens up into water due to the gravity of water.Along with the water yield within storage tank increases, ball float leaves lower locating piece, and ball float moves upward along litter band movable slider under the drive of buoyancy.When slide block arrives upper locating piece, band brake control valve core moves upward, thus venting cavity moves up, the magnet steel of the magnet steel and storage tank outer surface upper end that control spool top attracts each other, control valve wicking being lived by magnetic force, negative pressure mouth is closed, and venting cavity is connected with malleation mouth, and the air communication in interior accent with storage tank, whole storage tank casing recovers normal pressure.The valve gap of water inlet is automatically switched off due to pressure differential, and the valve gap of dewatering outlet discharges water owing to the action of gravity of water automatically opens up.When the water within storage tank is released, the water yield reduces, ball float moves gradually downward along litter band movable slider, when arriving lower locating piece and being pressed downward against, owing to controlling the summation of all parts gravity on spool more than the magnetic force between magnet steel, control spool to move downward, venting cavity also moves downward, when malleation mouth is closed, negative pressure in gas drainage pipeline passes through negative pressure mouth, venting cavity and interior accent and the air communication in storage tank casing, it is negative pressure in whole storage tank casing, water inlet valve gap is opened into water due to the action of gravity of water, dewatering outlet valve gap is automatically switched off due to pressure differential.Use the ball-cock assembly of two-bit triplet, the magnet steel being fixed on valve outer surface upper end is utilized to make control spool top can inhale at through hole topmost with the suction of the magnet steel controlling spool, avoid and collide the magnetic powder of output between magnet steel and cause the bad defect of action, valve body is directly to contact without with rubber seal rings for seal, extending the service life of ball-cock assembly with control spool.The ball-cock assembly using two-bit triplet instead of the effect that traditional multiple valves control can be only achieved, and decreases many links and thus reduces many trouble points, also mitigates the workload of the maintenance of workman, improve the job stability of tailrace.
Preferably, described storage tank bottom design is arcuate bottom and was connected with elbow from high to low to the lower mouth of a river from four weeks, one piece of quick discharge of eddy current of cinder in water and rock ballast with formation can be reduced or stop the situation generation that dewatering outlet block by rock (coal) powder (mud).
Preferably, described water storage case lid is that transparent material is made, two infalls being mutually perpendicular to centrage on storage tank lid are provided with two orthogonal level indicators, this utility model and horizontal plane absolute upright is ensured that when the blister in storage tank is at two level indicator centers, reduce the frictional resistance in ball float uphill process, extend the service life of ball-cock assembly, improve the reliability of work.
Preferably, the bend pipe downwardly extended along storage tank sidewall, bend pipe lower end joint noise reduction device are installed at described air inlet, avoid ash to enter through air inlet and enter into inside ball-cock assembly, blocking ball-cock assembly, simultaneously deafener noise reduction, it is to avoid in narrow and small environment, sound is excessive has influence on workmen.
Preferably, described malleation mouth and negative pressure mouth are connected with pipeline by deafener, it is to avoid in narrow and small environment, sound is excessive has influence on workmen.
Preferably, described storage tank casing and ball float use PVC material to make, and corrosion-resistant, lightweight, antistatic is durable in use indeformable.
Preferably, outside described storage tank on be provided with movable hand handle, convenient carry this tailrace, save the width spaces in tunnel, reduce hands with the colliding with of miscellaneous equipment and personnel so that appearance looks elegant.
The utility model has the advantages that:
(1) this utility model achieves the most levelling by two orthogonal level indicators, absolute guarantee's this utility model and the absolute upright of horizontal plane, reduces the frictional force in ball float uphill process, extends the service life of ball-cock assembly, improves the reliability of work；
