Description
Technical field
The present invention relates to a kind of pneumatic negative pressure jettison gear, be more particularly especially applied in the pneumatic automatic water drainage device of the interim methane gas extraction pipeline system of permanent methane gas extraction pipeline system and ground and down-hole under coal mine, be used as to discharge water, deslagging.
Background technology
According to the principle of mining after the first gas pumping of colliery rules and regulations; Working Environment of Underground Mine is comparatively severe; pump drainage pipe-line system mostly has the long-pending water and sediment of different Cheng Du; often cause suction side pipeline blockage; system pump drainage is not smooth, can make system produce concussion when serious, forces extraction Efficiency Decreasing; sometimes also can shut down because of normal pump drainage, to safety in production, bring a lot of hidden danger.The mode manually discharging water is taked in current most of colliery, closes extraction and discharges water afterwards again, and in cylinder, a cinder cannot be processed, and needs manual cleaning everyday.This mode shows and has restricted production.
Summary of the invention
The present invention is for avoiding the existing weak point of above-mentioned prior art, a kind of pneumatic negative pressure jettison gear is provided, integrates deslagging and discharge water, to effectively automatically getting rid of the long-pending water and sediment of pipeline, thoroughly solve the not smooth problem of pipe-line system pump drainage, guarantee safety of coal mines.
The design feature of the pneumatic negative pressure jettison gear of the present invention is: sealable water tank is set, cylinder valve and water level is set in described water tank and controls air valve, and correspond respectively to a high position and the low level of ball float the opening and closing that water level is controlled air valve; The periphery of described water tank arranges and comprises: the negative pressure water inlet of external supply channel is connected with water tank by cylinder valve; The air operated reversing valve that the air inlet port of external supply air line is controlled air valve by air-source treater, water level and is positioned at water tank outside is connected with water tank; Described air operated reversing valve has two mode bits, and one is that ball float is opened water level control air valve in a high position, cylinder valve is closed water inlet, and the air inlet port of external supply air line forms and is communicated with water tank; Another is that ball float is closed water level control air valve at low level, turn-offs external supply air line, and opens water tank exhaust passage; The water outlet adapter that non retern valve is installed is set in the bottom of described water tank.
The design feature of the pneumatic negative pressure jettison gear of the present invention is also: in described water tank, and the bottom that the is positioned at water tank stock guide that has been inclined to set, described stock guide is towards water outlet, to take over the lopsidedness at place.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, automatic-discharging of the present invention is effective, stable and reliable for performance, can effective guarantee pipe-line system unblocked, fully improve extraction efficiency, guarantee the safety in production in colliery.
2, the present invention can implement to discharge water in time according to the needs of working environment.
3, the present invention, without power supply, is automatically switched by supply air line, is particularly suited for, under coal mine, realizing Unmanned operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Number in the figure: 1 air inlet port, 2 first threeways, 3 air-source treaters, 4 air operated reversing valves, 5 gas-tpe fittings, 6 negative pressure water inlets, 7 cylinder valves, 8-sealing ring, 9 elbows, 10 second threeways, 11 altitude valves, 12 ball floats, 13 non retern valves, 14 water outlets are taken over, 15 water tanks, 16 stock guides.
The specific embodiment
Referring to Fig. 1, in the present embodiment, the form of structure of pneumatic negative pressure jettison gear is: sealable water tank 15 is set, controls air valve 11, and correspond respectively to a high position and the low level of ball float 12 opening and closing that water level is controlled air valve 11 at interior cylinder valve 7 and the water level of arranging of water tank 15; The periphery of water tank 15 arranges and comprises: the negative pressure water inlet 6 of external supply channel is connected with water tank 15 by cylinder valve 7; The air operated reversing valve 4 that the air inlet port 1 of external supply air line is controlled air valve 11 by air-source treater 3, water level and is positioned at water tank outside is connected with water tank 15; Air operated reversing valve 4 has two mode bits, and one is that ball float 12 is opened water level control air valve 11 in a high position, cylinder valve 7 is closed water inlet 6, and the air inlet port 1 of external supply air line forms and is communicated with water tank 15; Another is that ball float 12 is closed water level control air valve 11 at low level, turn-offs external supply air line, and opens water tank exhaust passage; The water outlet adapter 14 that non retern valve 13 is installed is set in the bottom of water tank 1.
Fig. 1 shows, in water tank, and the bottom that the is positioned at water tank stock guide 16 that has been inclined to set, stock guide 16 is towards water outlet, to take over the lopsidedness at 14 places.
In concrete enforcement, water tank 15 is to adopt the Q345 coiled sheet system cylindrical shell form that is welded, with ball float 12, control the action of altitude valve 11, altitude valve 11 promotes air operated reversing valve 4 and changes, stretching of the piston rod of air operated reversing valve 4 control cylinder valves 7, cylinder valve is used for closing negative pressure water inlet 6 and opens malleation entrance simultaneously enters in cylinder positive pressure air, and generation pressure discharges water, deslagging.
When the water level in water tank reaches the height of setting, ball float is in a high position, and water level is controlled air valve 11 and automatically opened, and promotes casing external pneumatic reversal valve 4 and commutates, thereby drive the piston forward in cylinder valve 7 to stretch out, and closes negative pressure water inlet 6; Then the other end of cylinder valve 7 generation barotropic gas directly enters in casing, and making increases positive pressure pressure in casing, realizes and discharging water and deslagging; When Water in Water Tanks position drops to, when height is set, ball float is in position, the end, then enters the state of discharging water, and completes the circulation that discharges water.
Check (non-return) valve 13, except to having discharged water back pressure effect, is avoided with under the state that in casing, liquid level decline casing inside and outside differential pressure is less simultaneously, and in blow-off line, gas is taken out.
The water outlet that water tank bottom is equipped with is taken over, and the deposit that is deposited on water tank bottom can be discharged in time, and water tank is cleaned on time.
The first threeway 2 shown in figure and the second threeway 10 are for the connection between gas circuit; Sealing ring 8 is for the shell portion of casing 15 and the sealing setting between case lid, and elbow 9 is connected to the lower end of negative pressure water inlet 6, and gas-tpe fitting 5 is arranged on case lid, for connecting gas circuit.
