Description
Technical field
The present invention relates to a kind of coal mine gas drainage technology, more particularly to a kind of coal mine gas extraction drill hole hole sealing device,
Belong to mining machine technical field.
Background technology
The polyurethane material that current coal mine gas extraction borehole sealing of hole is used, because product design is rectangular packed,
During sealing of hole, one side rectangle packed polyurethane material is cumbersome when bundling, and the time is long, inefficiency；On the other hand,
The complete parcel to whole drainage tube section is difficult to after the packed polyurethane material binding of rectangle, causes polyurethane material to expand
After foaming, filler can not be filled effectively to the space between drainage tube and drilling completely, cause drainage tube with drilling
Between the closely knit effect in space it is undesirable, easily occur conducting space.Above influence factor will cause that polyurethane sealing Porous materials are swollen
The sealing of hole effect of polyurethane material can not be had a strong impact on completely by mash gas pumping drilling section sealing after swollen, or even to follow-up
Grouting process is impacted, and ultimately results in mash gas pumping drilling that extraction negative pressure is low, gas density is low, extraction efficiency low one is
The appearance of row problem.
The content of the invention
The technical problem to be solved in the present invention is：A kind of coal mine gas extraction drill hole ring-type hole sealing device is provided, is passed through
Strong bond bar is wrapped in the surrounding of gas pumping pipe, raw material is extracted when using and intercepts pull bar, and two kinds of materials can be sufficiently mixed, complete
It is complete that drilling is blocked, solve above-mentioned technical problem.
The technical scheme is that：
A kind of coal mine gas extraction drill hole ring-type hole sealing device, it includes gas pumping pipe, is glued in the outside of gas pumping pipe
An annular aluminium foil bag is connected to, annular aluminium foil bag intercepts pull bar and is divided into two bins in left and right by two raw materials in the axial direction, respectively
Filled with expanded polyurethane component A and expanded polyurethane component B.
The annular aluminium foil bag seals the three part groups when, middle feed storage room and lower annular are sealed by upper, annular
Into it is feed(raw material)inlet that upper, annular is sealed before side is not loaded into two kinds of polyurethane components, and the centre of middle feed storage room is two
Raw material intercepts pull bar and separates, and lower annular sealing side is sealed with sealing machine.
The external diameter of the interior annular radius ratio gas pumping pipe of the annular aluminium foil bag wants big 5~10mm, annular aluminium foil bag
Axial length be 300mm~700mm.
The annular aluminium foil bag annular inboard has strong bond bar, and strong bond bar is located at the upper, annular of annular aluminium foil bag
Seal at the 5~10mm of downside on side, the width of strong bond bar is 20mm, bond the ring inner side two that scope is annular aluminium foil bag
In the range of each 120 ° of side.
The raw material intercepts the axial length 30~50mm of the length more than annular aluminium foil bag of pull bar.
Effective force effect of the invention is：
Compared with prior art, the present invention uses ring by above technical scheme during mash gas pumping drilling hole-sealing technology
Shape hole sealing device, can not only rely on the bonding strip on ring-type hole sealing bag, be rapidly secured on gas pumping pipe, and also achieve
Comprehensive parcel of the polyurethane sealing Porous materials to extraction pipeline, it is ensured that can be in drilling and pipe after the reaction of expanded polyurethane material
360 ° of even inflations in space between road, solve the packed polyurethane sealing of hole material of existing rectangle, and bundling operation is complicated, the time
Cannot be wrapped up during long, binding cannot completely by mash gas pumping drilling section sealing etc. during whole drainage tube, polyurethane reaction
Problem.Sealing of hole is carried out using prior art, the used time is generally required more than 5 minutes, and uses technology of the invention, it is only necessary to no
Sealing of hole can be completed by 1 minute, and sealing of hole effect is fine.The present invention is effectively guaranteed polyurethane sealing Porous materials to gas pumping
The sealing of hole effect of borehole profile, improves the sealing quality of polyurethane material, further increases mine gas extraction drilling and takes out
Negative pressure, gas density are adopted, substantially, operating efficiency is greatly improved onsite application effect.
