Description

Gas drainage pipeline negative pressure automatic slag-discharging water draining device

Technical field

The utility model relates to a kind of gas drainage under suction instrument, is specifically related to a kind of deslagging jettison gear.

Background technology

Along with the high request of Safety of Coal Mine Production, coal production enterprise first takes out afterwards at gas and digs, first take out afterwards that to adopt, mine after first gas production be necessary important measures.And the water, rock ballast, cinder etc. that are accompanied by gas in pre-gas pumping process are full of in pipeline.Often cause pipeline blockage, pump drainage is not smooth, and the system negative pressure is raise, and the pump drainage motor torque increases, and the drainage efficient decrease makes safety in production be subject to serious threat.Serious pipeline section, blocking pipeline, blocked gas pumping fully, causes potential safety hazard.

For addressing these problems, adopt at present artificial delivery box, automatic water drainage device and manual slag-discharging device drainage, slag discharges more.Artificial drainage, slag discharge reliability is strong, but workman's labour intensity is high, and the zone of management is limited.The know-why of automatic water drainage device is similar, and structural shape is varied.Particularly water intaking valve and discharging valve just have adopt that table tennis is formula, cover-plate type, cone, swing check valve etc.But particular surroundings and condition due to coal production, contain acidity, oiliness, coal dust, cinder in water, very easily stick on the component of equipment, form rust staining, the convex-concave point, cause all types of water intaking valves, draining valve ubiquity to be not closed completely, sealing gas leakage, make can't form negative pressure in water storage barrel, normally retaining, discharge water; Enter coal dust in tailrace, cinder etc. with water and very easily in tailrace, form precipitation, stop up water intaking valve and discharging valve, make the automatic water drainage device Frequent Troubles, cisco unity malfunction.

The utility model content

The purpose of this utility model is for above-mentioned the deficiencies in the prior art, and a kind of gas drainage pipeline negative pressure automatic slag-discharging water draining device is provided, and normal operation that can support equipment improves gas drainage under suction efficiency, makes gas drainage under suction work that a good condition be arranged.

The technical solution of the utility model realizes in the following manner: a kind of gas drainage pipeline negative pressure automatic slag-discharging water draining device, comprise water storage barrel, the place, deslagging dewatering outlet of water storage barrel bottom is provided with discharging valve, the gas drainage pipe water inlet on water storage barrel top is provided with water intaking valve, water storage barrel inside is provided with buoy, buoy is located in the connecting rod place, connecting rod top is connected with balancing pole, the lower main body of magnetic valve group is arranged on balancing pole, the upper main body of magnetic valve group is arranged on the atmospheric valve bottom, atmospheric valve is arranged on the water storage barrel top, the water storage barrel top is provided with negative pressure balance valve.

Described discharging valve and water intaking valve are bonnet formula valve body.

The base plate of described water storage barrel is the stainless steel base plate.

Described buoy is the stainless steel buoy.

The pressure differential that the utility model utilizes the interior negative pressure of gas drainage pipeline and atmospheric pressure to produce is carried out the switch closure of control appliance water inlet and dewatering outlet valve, thus the purpose that reaches automatic discharge and discharge water.Can make the normal draining of gas drainage pipe, deslagging.Prevent the formation of precipitation.The normal operation of support equipment, improve gas drainage under suction efficiency, makes gas drainage under suction work that a good condition be arranged.

The accompanying drawing explanation

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

Fig. 2 is discharging valve off position schematic diagram.

Fig. 3 is the discharging valve working state schematic representation.

The specific embodiment

As shown in drawings, the utility model comprises water storage barrel 8,6 places, deslagging dewatering outlet of water storage barrel 8 bottoms are provided with discharging valve 9, gas drainage pipe water inlet 3 places on water storage barrel 8 tops are provided with water intaking valve 10, water storage barrel 8 inside are provided with buoy 5; buoy 5 is located in connecting rod 11 places; connecting rod 11 tops are connected with balancing pole 4; the lower main body of magnetic valve group 7 is arranged on balancing pole 4; the upper main body of magnetic valve group 7 is arranged on atmospheric valve 2 bottoms; atmospheric valve 2 is arranged on water storage barrel 8 tops, and water storage barrel 8 tops are provided with negative pressure balance valve 1.Buoy 5 used is the stainless steel buoy.

In the utility model, cursory 5 are in water storage barrel 8 bottoms, and atmospheric valve 2, water intaking valve 10 and discharging valve 9 are closed naturally, and negative pressure balance valve is often opened.While starting working, the normal pressure in water storage barrel 8 progressively transfers negative pressure (in water storage barrel, negative pressure is consistent with negative pressure in extraction pipeline) under the effect of negative pressure balance valve.Atmospheric valve 2, discharging valve 9 close, water intaking valve 10 is opened.Now, the ponding of gas drainage pipeline the inside and foreign material will flow in the water storage barrel of automatic slag-discharging water draining devices by the water intaking valve 10 joined with pipeline, with increasing of rate of water added, the rising gradually of cursory 5 in water storage barrel, and can promote balancing pole 4 risings, while reaching certain height, main body and the rapid combination of lower main body meeting on the magnetic valve group, negative pressure balance valve 1 is closed, and atmospheric valve 2 is opened, water intaking valve 10 is closed under the pipeline suction function, and the interior negative pressure of water storage barrel 8 is converted to malleation.Discharging valve 9, owing to losing negative-pressure sucking, recovers the nature closed condition, and opens under the static pressure of retaining inner bucket water, and the water in bucket and foreign material etc. are discharged automatically by discharging valve.Along with the decline of water level in water storage barrel, cursory moving down, pull open the magnetic valve group, and negative pressure balance valve 1 is opened, and atmospheric valve 2 is closed, and the pressure right side in water storage barrel transfers negative pressure to by malleation, and discharging valve is closed, and enters next working cycles.

Described discharging valve 9 and water intaking valve 10 are bonnet formula valve body, and valve gap is made the form of bonnet.As shown in Figures 2 and 3, when quitting work, valve gap naturally droops, and covers valve port, avoids entering foreign material.While in water storage barrel, forming negative pressure, the bonnet base covers on the base plate of valve, the contact of formation face.Along with the increase bonnet top of negative pressure indent gradually, outer, bonnet base slowly upwarps, and interior edge being pressed on valve port tightly, form the loop wire contact, reduced the face contact, ensured the sealing of valve.In addition, the utility model has strengthened the diameter of discharging valve and water intaking valve, makes static pressure and Water discharge flow speed in water storage barrel increase, and has solved the foreign material precipitation such as coal dust cinder and impurity and has sticked problem.

The base plate 8-1 of described water storage barrel 8 is the stainless steel base plate, can solve the problems such as corrosion, spot.
