Background technology
With the increasing of mining depth, crustal stress is further obvious to the influence of coal mine down-hole tunnel gas emission.
Laboratory and engineering site pay attention to influence of the stress factors to it further when testing coal body adsorption-desorption rule.It is existing large-scale
Servo-pressing machine has good effect when establishing and simulating stress field, but its build is heavy, expensive, in practical operation
Flow is complex and needs to provide power supply and special coal sample tank, and when the adsorption experiment of gas needs long under stress
Between to coal body carry out adsorption saturation, such as using large pressing machine to coal body carry out stress loading, then expense is huge, therefore it can not
Extensive application and popularizations are carried out in engineering site, and it is less efficient when laboratory carries out related simple experiment.
The content of the invention
The purpose of this utility model be to provide it is a kind of can loading stress coal sample tank, can overcome existing for prior art lack
Fall into.
The purpose of this utility model is achieved in that its architectural characteristic is as shown in Figure 1.It includes blind flange 1, diffusing
Lid 2, canister 3, sliding block 4, jack 5, pressure duct 6, pressure gauge 7, loading oil pump 8, welded flange 9.Coal sample can body structure
To be welded with the stainless steel canister 3 of flange and upper and lower blind flange lid 1 and loading jack 5.The upper end of canister 3 is screwed with diffusing lid
2, lower end insertion jack 5, sliding block 4 of the inside equipped with regulation loading length.
The blind flange 1, it is formed with annular seal groove 102 towards the one side of canister 3, for installing seal O-ring,
There are four bolts hole 101 in blind flange card, upper flange lid 1 directly contacts with welded flange 9, lower flange lid 1 and jack 5
Lower end in contact, is sealed with bolt presses.Jack 5 can also be taken out when stress loading experiment need not be carried out, make to be embedded with O-ring
Blind flange 1 directly contacted with flange 9, sealed with bolt presses.
The diffusing lid 2, it is that one block of cylinder stainless steel is fast, its side is formed with external screw thread 201, has at upper and lower end face some
Air-vent 202, diffusing lid 2 can be screwed into by the upper end of coal sample canister 3, coal sample covered.
The sliding block 4, it is cylinder piece of stainless steel, its diameter is slightly smaller than the internal diameter of canister 3, if can highly be placed according to coal sample
Dry sliding block 4, jack 5 is set to be unlikely to no to scale work.
The canister 3, it is heavy wall stainless steel tube, flange is welded with its two-port, the top of canister 3 is formed with internal thread 302,
And passage 301 is respectively provided with four direction all around, the inwall of passage 301 is formed with stomata internal thread 303, under canister 3
Portion is formed with step-like structure 304, and during stress loading, step-like structure 304 is in contact with the upper surface of jack 5.
The jack 5, its diameter are slightly less than the lower end interior diameter of coal sample canister 3, and it is close that the upper surface of jack 5 is formed with jack
Groove 502 is sealed, for placing O-ring, jack 5 passes through the external pressure gauge 7 of pressure duct 6 and loading oil pump 8.
The advantages of the utility model and good effect are can to realize coal body with relatively low cost after using this coal sample tank
Gas adsorption desorption experiment under long-term stress loading, while conveniently moving are smaller to lab space and environmental requirement.

Embodiment
As shown in figure 1, coal sample canister 3 is placed vertically, by jack 5 of the bottom of canister 3 insertion equipped with sealing ring, and spiral shell is used
Bolt and blind flange 1 are blocked, and tightening bolt makes the upper surface of jack 5 be in contact with step-like structure 304, so as to by O-ring
Deformation is compressed, to reach the purpose of coal sample tank lower end sealing；Sliding block 4 is fallen into by the upper port of canister 3, with the phase of jack piston 501
Contact, the quantity of sliding block 4 is depending on the height of coal sample, and coal sample height is with most lower no more than the internal thread 302 of canister 3 after adding sliding block 4
End is advisable；After loading coal sample, diffusing lid 2 is screwed into canister 3, the upper end of canister 3 uses the blind flange 1 embedded with seal O-ring to cover,
Bolt is tightened, sealing ring is compressed deformation to reach the purpose of the upper port of canister 3 sealing；Four, coal sample tank top structure and specification
All identical stomata 301 respectively external vacuum line, loading line, diffuse pipeline and pressure sensor；Filling coal sample has sealed
After finishing, it can be pressurizeed by the outer loading oil pump 8 that connects of jack 5, move up jack piston 501, extrude coal sample, lead to
Excess pressure table 7 can read coal sample pressure value；According to the registration research of pressure gauge 7 under particular load stress coal sample
Adsorption and desorption characteristics.
