Description
Technical field
The utility model belongs to coal mine pipeline technical field, relates to a kind of coal mine gas fast pumping device concretely.
Background technology
The armored pipes that coal mine gas extraction pipeline is connected with threeway by the PVC hole sealing tube being placed in hole, coal seam, the exhaust line that is provided with some threeways and the flexible pipe be connected between this armored pipes and PVC hole sealing tube are formed.There is following problem in the coal mine gas evacuation system of this structure: one, PVC glue is adopted to be connected by flexible pipe with PVC hole sealing tube by armored pipes during owing to utilizing for the first time, the mode of cut tightly can only be taked to reclaim owing to pasting during recovery, the armored pipes adopting cut to cross when again multiplexing is sleeved on collecting pipe joint and PVC sealing of hole joint, cause gap space, impact boring concentration and negative pressure; Its two, when this system drawing-off gas, directly the methane gas with high-moisture and impurity is discharged by pipeline, therefore as easy as rolling off a log to pipeline formed blocking, affect the discharge efficiency of gas, directly danger formed to mine.
Utility model content
The purpose of this utility model is just to provide a kind of rational in infrastructure, and can have the high coal mine gas fast pumping device of pump drainage efficiency.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of coal mine gas fast pumping device, its structure comprises
The PVC hole sealing tube in coal bed drilling can be inserted, be provided with the armored pipes that the exhaust line of some threeways is connected with threeway and the flexible pipe be connected between this armored pipes and PVC hole sealing tube; It is characterized in that:
The end of described PVC hole sealing tube is provided with pressure measuring mechanism, the end of described armored pipes is provided with connection ball valve, the two ends of described flexible pipe are provided with respectively with described pressure measuring mechanism be connected the connection jig that ball valve connects.
The additional technical feature forming above-mentioned coal mine gas fast pumping device also comprises:
---the end of described exhaust line is provided with slagging device;
---described slagging device is made up of the storage slag container being provided with slag notch;
---described storage slag container is provided with slag releasing channel and drain hole;
---described exhaust line end is provided with air draft mechanism and through the gas main pipeline of finding time of threeway mechanism connection.
Coal mine gas fast pumping device provided by the utility model compared with prior art, have the following advantages: one, owing to being provided with pressure measuring mechanism in the PVC hole sealing tube end forming this device, the end of armored pipes is provided with connection ball valve, and the two ends of connecting hose are provided with respectively with above-mentioned pressure measuring mechanism be connected the connection jig that ball valve connects, therefore make flexible pipe and PVC sealing of hole pipe end and armored pipes be active link, when can overcome again multiplexing there is gap space and the problem affecting hole concentration and negative pressure with being connected between the two in flexible pipe; Its two, because the exhaust line end at this device is provided with slagging device, therefore can effectively prevent impurity from forming blocking to pipeline and affect the discharge efficiency of gas and further mine directly formed to the generation of dangerous phenomenon; Its three, owing to being provided with slag releasing channel and drain hole in the bottom forming storage slag container, therefore the moisture in methane gas can be reduced, effectively can avoid steam to extract duct in the danger becoming corrosion and pipe bent position blocking; They are four years old, the end being provided with pressure measuring mechanism and armored pipes in the PVC hole sealing tube end of this device is provided with connection ball valve, the gas pressure in coal bed drilling can be monitored at any time and closedown is opened to flexible pipe, to overcome when the generation of pouring in down a chimney phenomenon during its pressure is lower than exhaust line during gas pressure.
Accompanying drawing explanation
The structural representation of the coal mine gas fast pumping device that Fig. 1 provides for the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the structure of the coal mine gas fast pumping device that the utility model provides and assembling process are described in further details.
Be illustrated in figure 1 the structural representation of the coal mine gas fast pumping device that the utility model provides.The structure forming this device comprises can insert that the end of holing in 2, coal seam 1 is provided with the PVC hole sealing tube 3 of pressure measuring mechanism 6, the exhaust line 5 being provided with some threeways 4, its end of being connected with threeway are provided with the armored pipes 8 connecting ball valve 7, by screw thread or be connected jig 9 and connected by flexible pipe 10 between connection ball valve 7 with pressure measuring mechanism 6; Be provided with in the end of above-mentioned exhaust line both can be spiral separation mechanism, also can be provided with slag releasing channel 11 container 12 form slagging device.
Its operating principle is: detect gas pressure in coal bed drilling by pressure measuring mechanism, when its pressure is less than gas pressure in exhaust line, then leads to access valve and closed by flexible pipe; When its pressure is greater than gas pressure in exhaust line, then lead to access valve flexible pipe is opened, by air draft mechanism, its gas being drawn through flexible pipe enters in exhaust line, then the slagging device being arranged at this line end is entered, be stored in by cinder in the container forming this slagging device, purer methane gas is then discharged through pipeline.
In the structure forming above-mentioned coal mine gas fast pumping device:
---in order to improve the water content reduced in gas further, above-mentioned storage slag container is provided with the drain hole 13 be communicated with storage tank 17;
---in order to improve the discharge efficiency of gas further, the end of exhaust line is provided with air draft mechanism 14 and the gas main pipeline 16 of finding time be communicated with through threeway mechanism 15.
