Description

Automatic slag-discharging water draining device

Technical field:

Facility under a kind of coal mine is used for fire damp pump drainage pipe-line system automatic slag-discharging water draining, prevents the gas exhaust pipeline blockage, guarantees that the gas exhaust pipeline is unobstructed, thereby makes gas exhaust system energy operate as normal, guarantees the safety of underground work.

Background technology:

The coal mine gas pump drainage is important measures of administering gas, in the pump drainage process, has foreign material such as certain water and cinder, spoil slag to be accompanied by Device in Gas and flows to into the gas exhaust pipeline.At present, for addressing this problem, the unit of pump drainage gas generally all organizes special messenger's deslagging that manually discharges water in the down-hole, but because manually-operated untimely, not in place, the pipeline blockage problem still often takes place.

Summary of the invention:

The purpose of this utility model is foreign material, automatic slag-discharging water draining devices safe and reliable to operation simple in structure such as water, cinder in a kind of firedamp drainage extraction pipeline automatically of design.

The scheme of the utility model technical solution problem is:

The utility model is made up of component such as the threeway that has flange-interface, water storage tanks, and threeway inserts in the gas exhaust pipeline two logical flange-interfaces, airtight being fastenedly connected of flange on another vertical flange-interface and the water storage tank.

Feature of the present utility model is, the vertical flange interface end that threeway links to each other with water storage tank, an affixed water intaking valve, the bottom of water storage tank connects a discharging valve, carriage is arranged in the water storage tank, the floating chamber is arranged on the carriage, ball float in floating chamber and the water intaking valve is flexible coupling, have only when float along with the water level rising of water storage tank the floating chamber, rise to the valve port of water intaking valve in the water storage tank that coupled ball float could cause under the effect of negative pressure in the gas exhaust process, close water intaking valve, the outer gag lever post that prevents its displacement that is with of floating chamber.

Compared with prior art, advantage of the present utility model is that simple in structure, the work of automatic slag-discharging water draining has just been finished in a combination with seldom several component, has saved manpower, and has guaranteed normal, the safe operation of gas exhaust pipe-line system.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

The specific embodiment:

Referring to Fig. 1, the threeway 10 that has flange-interface is in use by two logical flange-interfaces are inserted in the pipeline of drawing-off gas system, another vertical flange-interface 11 and water storage tank 30 are by bolt and sealing mat is airtight is fastenedly connected, in the flange of this interface, and affixed water intaking valve 20.Water intaking valve 20 is made up of parts such as valve body 21, end cap nut 27 and ball floats 26, inlet opening 22 and ball float chamber 25 are arranged in the valve body 21, both junctions form valve port 24, and ball float 26 is arranged in the ball float chamber 25, and ball float 26 is spacing in ball float chamber 25 by the end cap nut 27 that spiral is connected valve body 21 lower ends; Weep hole 28 is arranged on the end cap nut 27; Carriage 50 is arranged in the water storage tank 30, floating chamber 40 is arranged on the carriage 50, floating chamber 40 is flexible coupling by the ball float 26 in line 41 and the water intaking valve 20; Floating chamber's 40 sinkings are on carriage 50 time, and ball float 26 is subjected to the tractive of line 41, can't on float to valve port 24 places of water intaking valve 20; Around the floating chamber 40, the gag lever post 70 that prevents its displacement is arranged, according to the shape of floating chamber 40, gag lever post 70 is at least three.The bottom of water storage tank 30 connects a discharging valve 60, discharging valve 60 is made up of parts such as valve body 61, end cap nut 67 and ball floats 66, drain hole 62 and ball float chamber 65 are arranged in the valve body 61, both junctions form valve port 64, ball float 66 is arranged in the ball float chamber 65, and ball float 66 is spacing in ball float chamber 65 by the end cap nut 67 that spiral is connected valve body 61 lower ends; Have weep hole 68 on the end cap nut 67.The diameter of the inlet opening 22 in the water intaking valve valve body 21 is generally in 30 to 65 millimeter, and according to the size of gas exhaust system internal pressure and the size of inlet opening 22 diameters, the weight of floating chamber 40 is generally about 0.5 to 2.8 kilogram.

During work, insert in the threeway in the drawing-off gas system pipeline, the gas air-flow flows through fast, in water storage tank 30, form negative pressure, though the ball float 26 in the water intaking valve 20 is subjected to suction, but because of its tractive that is connected the line 41 in the floating chamber 40, can't rise to valve port 24, so water intaking valve 20 is in open mode; And the ball float 66 in the discharging valve 60 is drawn to valve port 64 because of the effect of negative pressure, and discharging valve is in closed condition 60 this moments, and water storage tank 30 becomes the closed container that negative pressure is arranged at this moment; Foreign material such as water in the gas air-flow and cinder, spoil slag because of action of gravity, enter water storage tank 30 by water intaking valve 20 when flowing by threeway with Device in Gas, foreign material natural sedimentations such as cinder are in the bottom; Along with the rising of water level in the water storage tank 30, floating chamber's 40 come-ups, the ball float in the water intaking valve 20 also increases because of suction function for 26 this moments, and finally is increased to valve port 24, closes water intaking valve 20; After water intaking valve 20 is closed, negative pressure in the water storage tank 30 slowly reduces, ball float 66 suffered suction in the discharging valve 60 reduce, and fall under the pressure effect of ball float 66 final water in water storage tank 30, thereby open discharging valve 60, foreign material such as the cinder in the water storage tank 30, spoil slag and water are discharged automatically, and be first deslagging (slag is deposited in the bottom), back draining, such result is, valve body 61, end cap nut 67 and ball float 66 are relatively cleaner, thereby guarantee long-time normal operation of the present utility model.After deslagging discharged water, along with the reduction of water level in the water storage tank 30, floating chamber 40 descended, and the ball float 26 in the water intaking valve 20 is subjected to the tractive of line 41 and descends, and water intaking valve 20 is opened, and the ball float 66 in the discharging valve 60 is picked up again, and discharging valve 60 cuts out, so periodic duty.

For guaranteeing result of use of the present utility model, can there be rubber gasket 23 at valve port 24 places in the valve body 21 of water intaking valve 20, and this packing ring 23 is fixed on the valve body 21 by screw 90; Also can there be rubber gasket 63 at valve port 64 places in the valve body 61 of discharging valve 60.

Ball float

26,66 in water intaking valve 20 and the discharging valve 60 can be made with polypropylene PP light plastic.The bottom of water storage tank 30 is taper, and water storage tank 30 has supporting leg 70.
