Description
Technical field
The utility model relates to a kind of automatic water drainage device, especially relates to a kind of automatic water drainage device of mine gas extraction pipe.
Background technology
At present, in coal production process, need to carry out extraction work to gas, the a large amount of water of frequent in the drainage tube of gas, therefore need on gas pumping pipe, tailrace be installed, an existing tailrace part adopts manual type to discharge water, this tailrace uses the common water tank with valve, needing full-time staff to be timed to discharge water a little to open valve discharges water, not only time-consuming, and usually cause not in time drainage tube pipeline blockage because discharge water, have a strong impact on the normal operation of gas drainage system.
Some tailrace is to adopt floating ball tank formula, as patent 200720016958.5, ball float is in the inner installation of water tank, ball float drives by connecting rod the stopper that discharges water, after water has been expired, ball float pulls stopper to carry out retaining and the action that discharges water, this tailrace is simple in structure, cheap, but be not suitable under coal mine, because the water collecting in coal extraction pipe is not tap water, but very dirty cinder water, and contain number of chemical element, very easily corrosion water tank, and owing to there is no external force, only use float buoyancy to cause action unreliable, when this tailrace has often just been installed, result of use is pretty good, after several weeks, cannot guarantee normal work with regard to dirty, be failure to actuate such as there is ball float, retaining stopper fits badly, the stopper that the discharges water various faults such as do not open.
Emerging tailrace has a kind of use electronic sensor sensed water level and uses motor operated valve control to discharge water, as patent 201020107207.6, but colliery scene is to using this kind of tailrace to have misgivings, because, in gas pipe, be the methane gas that can light, will directly cause the serious accident of gas explosion once electronic product mistake is quick-fried.
Patent 201020041256.4 proposes a kind of pneumatic automatic water drainage device, valve, retaining and discharge water gas control draught excluder, one way valve, tracheae that the ball float of this kind of tailrace, floating ball rod, ball float drive are all placed in water tank, in situ overhaul is found, in water tank, a large amount of impurity, scales etc. all can cause and have a strong impact on the valve in water tank, cylinder piston, tailrace can not be worked for a long time reliably, and be only three weeks normal working hours.If float connecting rod is moved on to water tank outside outward, because float and connecting rod are all to adopt stainless steel, float overcomes weight and the weight of the connecting rod power that offers outside valve body of falling self and will reduce a lot, the buoyancy of float is relevant with float size again, float volume is large, and buoyancy is large, but the water tank space that can account for a large amount of; Float volume is little, and buoyancy is too little again.Float connecting rod also has a problem to need to solve after moving on to water tank outside outward: connecting rod is easy to by water or other contaminating impurities through the hole of water tank.
In sum, how automatic water drainage device control section can be moved on to water tank outside outward, and neither to increase float volume, not use again electronic mode, can also guarantee safety, implement retaining reliably, the work that discharges water, be the knotty problem of coal mine gas drainage tube automatic water drainage device always.
Summary of the invention
In order to solve the deficiency of existing tailrace, the utility model provides a kind of automatic water drainage device of mine gas extraction pipe, it does not use electronic mode and adopts safe and reliable coal mine compressed air to do power, can carry out automatic draining according to the water level in tailrace, enough float buoyancy is provided under the prerequisite that does not increase float volume, can effectively anti-sealing or other contaminating impurity push rods through the hole of water tank, can guarantee safe, implement retaining reliably, work discharges water.
The utility model solves the technical scheme that its technical problem adopts: automatic water drainage device comprises water tank, pneumatic operated valve A, pneumatic operated valve B, pneumatic operated valve C, inching valve, time-delay valve, float and push rod, the water inlet of water tank is connected with gas pumping pipe by pneumatic operated valve A, the dewatering outlet of water tank is connected with ambient air by pneumatic operated valve B, the air inlet port of water tank is connected with compressed air hose by pneumatic operated valve C, the driving control end of pneumatic operated valve A, pneumatic operated valve B, pneumatic operated valve C is connected with time-delay valve, and time-delay valve is connected with inching valve and by inching valve control; Float is placed in the inside of water tank, push rod passes water tank by a hole, push rod exceeds the push rod chamber of tank top through one of the location arrangements of water tank, push rod lower end is positioned at water tank and is connected with the top of float, and push rod upper end is positioned at the outside of water tank, and push rod upper end connects a lever, lever divides taper end and butt end, the weight of taper end is less than the weight of butt end, between taper end and butt end, has lever shaft, and lever can rotate around lever shaft; Taper end is connected with push rod, and push rod moves up and down and drives lever to rotate around lever shaft, and triggers the switching of inching valve.
The state of tailrace in retaining at ordinary times, pneumatic operated valve A is in an open position, the water inlet of water tank and gas pumping pipe are in connected state, pneumatic operated valve B is in the closed position, the dewatering outlet of water tank is in closed condition, pneumatic operated valve C is in the closed position, and the air inlet port of water tank is in closed condition, and the ponding in gas pumping pipeline can flow in water tank; Water in water tank reaches after float height, float is risen by buoyancy and then opens inching valve by push rod, after inching valve is opened, time-delay valve is in Time Delay Opening state, the driving control end air inlet of pneumatic operated valve A, pneumatic operated valve B, pneumatic operated valve C, and then complete and control opening of the opening of the closing of pneumatic operated valve A, pneumatic operated valve B, pneumatic operated valve C, therefore water tank inlet is closed, delivery port is opened, compressed air is in air inlet port enters into water tank, and the water in water tank is released; Time-delay valve cuts out after the delay time of setting, and controls pneumatic operated valve A, pneumatic operated valve B, pneumatic operated valve C reset, and pneumatic operated valve A opens, pneumatic operated valve B closes, pneumatic operated valve C closes.After water level declines, float and push rod decline, and inching valve recovers closed condition, and water tank enters again retaining state.
Push rod exceeds the push rod chamber of tank top through one of the location arrangements of water tank.Be convenient to anti-sealing or other contaminating impurity push rods hole through water tank.
Push rod upper end connects a lever, and lever divides taper end and butt end, and the weight of taper end is less than the weight of butt end, between taper end and butt end, has lever shaft, and lever can rotate around lever shaft; Taper end is connected with push rod, and push rod moves up and down and drives lever to rotate around lever shaft, and triggers the switching of inching valve.Due to leverage, the weight of butt end can balance the weight of push rod, float, taper end, in the situation that the required touching power of inching valve is certain, can effectively reduce required float buoyancy, and then reduces the volume of float, increases the dischargeable capacity of water tank.
The beneficial effects of the utility model are, have solved the automatic draining problem of mine gas extraction pipe tailrace, simple in structure, easy to use, have saved manpower.
