Description
Technical field
The utility model belongs to coal sample saturation technique field, more particularly to vacuum saturation coal sample device.
Background technology
Hydraulic fracturing technology is greatly facilitated effect to cbm development, but a series of asking also is occurred in that in application process
Topic.Hydraulic fracturing needs to consume great lot of water resources, it is difficult to implement on a large scale in water resources shortage, densely populated areas；Fracturing fluid
Containing a large amount of chemical addition agents, underground water level local environment can be polluted.Therefore, in the urgent need to being substituted using novel fluid
Aqueous fracturing fluid.Liquid nitrogen colorless and odorless, temperature are extremely low, pollution-free, and are widely used.Liquid nitrogen pressure break is damaged to coal body pore structure
Research in terms of wound is increasingly subject to pay attention to, and the different pore size Volume Changes after coal sample liquid nitrogen before processing can be by nuclear magnetic resonance skill
Art is detected, and needs to carry out coal sample vacuum saturation water process in detection process.Existing coal sample vacuum saturation device structure is answered
It is miscellaneous, it is not convenient to use.
Utility model content
The utility model is in order to solve weak point of the prior art, there is provided a kind of compact conformation, true easily to operate
Empty saturation coal sample device.
In order to solve the above technical problems, the utility model is adopted the following technical scheme that：Vacuum saturation coal sample device, including it is full
With device and vacuum extractor, closed glass cover is screwed on base, and closed glass flaring sets along and base between
There is sealing ring, the glass beaker for filling coal sample is placed in the closed glass cover with handle, base left end is connected to by water pipe
Water tank, right-hand member is connected to vavuum pump by exhaust tube, and exhaust tube is provided with vacuum meter and stop valve.
The position of water tank is higher than closed glass cover, and the right-hand member of water pipe is extended to more than base, and mouth of pipe bending down, is taken out vertically
Tracheae left end is extended to more than base.
Using above-mentioned technical proposal, the utility model has the following advantages that.
1st, the position of water tank is higher than closed glass cover by the utility model, and the right-hand member of water pipe is extended to more than base, the mouth of pipe
Vertically down, exhaust tube left end is extended to more than base for bending；Using said apparatus, simple structure is easy to use, is easy to utilize
Water in pressure official post water tank enters glass beaker by water pipe.
2nd, closed glass cover of the present utility model is screwed on base, and closed glass flaring is along and base between
It is provided with sealing ring；The utility model is easy to operate, and the sealing of closed glass cover is ensure that well, is conducive to quick to closed
Cloche is vacuumized.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein, 1- water tanks；2- water；3- water inlet switch；4- water pipes；5- handles；6- closed glass covers；7- coal samples；8- glass
Beaker；9- exhaust tubes；10- screws；11- sealing rings；12- bases；13- vacuum meters；14- stop valves；15- vavuum pumps.
Specific embodiment
As shown in figure 1, vacuum saturation coal sample device of the present utility model, including saturation device and vacuum extractor, it is closed
Cloche 6 is fixed on base 12 by screw 10, and sealing ring 11 is provided between the edge of closed glass cover 6 and base 12, is carried
The glass beaker 8 for filling coal sample 7 is placed in the closed glass cover 6 of handle 5, the left end of base 12 is connected to water tank 1 by water pipe 4,
Right-hand member is connected to vavuum pump 15 by exhaust tube 9, and exhaust tube 9 is provided with vacuum meter 13 and stop valve 14.The utility model structure
Simply, it is easy to use, be rapidly saturated coal sample.
The position of water tank 1 is higher than closed glass cover 6, and the right-hand member of water pipe 4 extends to base more than 12, and the mouth of pipe bends vertical court
Under, the left end of exhaust tube 9 extends to base more than 12.
The course of work of the present utility model is：First, the glass beaker 8 that will fill coal sample 7 is placed on above base 12, is held
Closed glass cover 6 is gently buckled in handle 5 upper end of sealing ring 11 on base 12, tightens screw 10, it is ensured that closed glass cover 6 it is close
Feng Xing；Then, water inlet switch 3 is opened, because the water 2 in pressure differential water tank 1 can enter glass beaker 8 along water pipe 4, until glass
Water 2 in glass beaker 8 floods coal sample 7, closes water inlet switch 3, now opens stop valve 14, opens vavuum pump 15, carries out negative pressure
More than suction filtration 8h, the air in closed glass cover 6 can be extracted by exhaust tube 9, during the registration stabilization of the display of gauge 13,
Vavuum pump 15 and stop valve 14 are closed, closed glass cover 6 is opened, the coal sample crossed to saturation carries out nuclear magnetic resonance experiment test.
