Abstract
The utility model discloses a multifunctional connecting device for a coal mine gas extraction drill hole, which comprises a main pipeline gas extraction connecting port (1) and a drill hole gas extraction connecting port (2). The multifunctional connecting device is characterized in that the main pipeline gas extraction connecting port (1) is welded with a vertical pipe (3) at the upper portion of the vertical pipe (3), the drill hole gas extraction connecting port (2) is welded with the vertical pipe (3) at the upper and middle portion of the vertical pipe (3), a deslagging pipeline (5) is welded with the vertical pipe (3) at the bottom of the vertical pipe (3), a water discharging pipeline (4) is welded on the deslagging pipeline (5), and a movable cover plate (6) is covered on the water discharging pipeline (4). The device can enable gas to be separated from water and coal slag, achieves automatic water discharge and manual slag removing, eliminates blocking of a main extraction pipeline caused by ponding and the coal slag, guarantees stability of a gas extraction system and improves mine gas extraction effect.
Description
Technical field
The utility model relates to a kind of coal mine gas extraction borehole linkage, relates in particular to a kind of multi-functional coal mine gas extraction borehole linkage.
Background technology
Extraction borehole is connected with main extraction pipeline under the coal mine, adopts direct the connection with trunk line perhaps of flexible pipe of diameter 50mm to process a plenum chamber mostly, and will hole is connected with plenum chamber, and plenum chamber links to each other with main extraction pipeline more then.This device can focus on gas in the extraction plenum chamber; Carry out gas pumping through main extraction pipeline then; But adopt this device mash gas extraction, can not realize deslagging and discharge water automatically, cinder in the extraction process in boring appears in regular meeting and crevice water are with extraction negative pressure entering extraction trunk line; Cause the blocked and ponding of extraction trunk line, influence gas pumping.
The utility model content
The technical problem that the utility model will solve provides a kind of Device in Gas and can separate automatically with water (cinder), realize discharging water automatically and the multi-functional coal mine gas extraction borehole linkage of artificial slagging-off, gas pumping system stability.
For solving the problems of the technologies described above, a kind of multi-functional coal mine gas extraction borehole linkage of the utility model comprises trunk line connector, the boring connector of bleeding of bleeding, and it is characterized in that: in riser upper, the trunk line connector of bleeding welds with standpipe; In the standpipe middle and upper part, connector and the standpipe welding of bleeding of holing; In riser bottom, slagging-off pipeline and standpipe welding; On the slagging-off pipeline, be welded with blow-off line; On blow-off line, be stamped removable cover.
Compared with prior art, the beneficial effect that the utlity model has is:
1, the utility model is through being provided with a standpipe, can realize that Device in Gas separates with water, cinder automatically.
2, because the slagging-off pipeline of the utility model riser bottom is provided with blow-off line, the pressure that produces at ponding height gravity is during greater than the extraction negative pressure, and ponding just can flow out from the adjutage road junction automatically, thereby realizes discharging water automatically.
3, because the utility model is welded with the slagging-off pipeline in riser bottom; There is the special messenger to make regular check on the cinder situation of deposition in the standpipe at the scene in the management process; Thereby when finding cinder is arranged, can in time carry out manual work slagging-off cleaning; Eliminate the stopping state that causes because of cinder and taken place, guaranteed the stable of gas pumping system.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Fig. 1 is the structural representation of a kind of multi-functional coal mine gas extraction borehole linkage of the utility model.
The specific embodiment
As shown in Figure 1, a kind of multi-functional coal mine gas extraction borehole linkage comprises trunk line bleed connector 1, the boring connector 2 of bleeding, on standpipe 3 tops, and trunk line bleed connector 1 and standpipe 3 welding; In standpipe 3 middle and upper parts, connector 2 and standpipe 3 welding of bleeding of holing; In standpipe 3 bottoms, slagging-off pipeline 5 and standpipe 3 welding; On slagging-off pipeline 5, be welded with blow-off line 4; On blow-off line 4, be stamped removable cover 6.
After drilling construction finishes, carry out sealing of hole, be connected to boring through flexible pipe behind the drilling and sealing and bleed on the connector 2, bleed through another root flexible pipe and trunk line then and just can on main extraction pipeline, carry out mash gas extraction after connector 1 is connected.In the process of mash gas extraction; Gas and water in the boring, cinder can be under the extraction action of negative pressure along the boring connector entering standpipe 3 of bleeding, at this moment under the effect of gravity, Device in Gas can be separated with water, cinder; Device in Gas can upwards be assembled; Get into main extraction pipeline through bleed connector 1 of trunk line, and water and cinder will sink, and collect in riser bottom.Meeting arranges the special messenger regularly open the cinder situation that deposit in the slagging-off pipeline 5 inspection standpipes 3 of standpipe 3 bottoms in the management process at the scene, and the discovery cinder is in time cleared up.Removable cover 6 is stamped in blow-off line 4 exits on slagging-off pipeline 5; Removable cover 6 can cover the outlet of blow-off line 4 because of the deadweight auto-closing under the effect that does not have external force (water); Fresh air gets into when preventing extraction; The pressure that produces when standpipe 3 bottom ponding height gravity is during greater than the extraction negative pressure, and ponding just can back down removable cover 6 from the outlet of blow-off line 4, flows out automatically.
Use a kind of multi-functional coal mine gas extraction borehole linkage of the utility model; Device in Gas is separated with water (cinder) automatically; Realize discharging water automatically and artificial slagging-off; Eliminate main extraction pipeline because of the obstruction that ponding and cinder cause, guaranteed the stable of gas pumping system, improved mine gas extraction effect.
