Description
Technical field
The present invention relates to technical field of experiment equipment, especially a kind of improved high pressure content method gas adsorption instrument coal sample
Tank.
Background technology
At present, gas accident is still the important threat of Safety of Coal Mine Production process, and some basic parameters are carried out to colliery
Measure be prediction coal-mine gas content, pressure so that it is determined that the effective means of gas danger classes, among these to coal sample
It is a kind of conventional effective means that absorption constant, which carries out test,.When carrying out coal sample absorption constant determination experiment, it is necessary to use height
Press volumetric method gas adsorption instrument.When analyzing coal sample, it is necessary to pour the gas of certain pressure to coal sample first, and keep
Adsorption equilibrium is made up at certain temperature, this process generally requires 8 more than hour.It is general when being tested now
Way is that coal sample tank is placed in water bath with thermostatic control when carrying out gas High Pressure Absorption balance, and water bath with thermostatic control is set in the temperature of needs
Degree, relief water bath with thermostatic control keep working condition until coal sample reach adsorption equilibrium.Such thermostatic mode result in substantial amounts of
Manpower is consumed with financial resources, first, and water bath with thermostatic control holding work can cause experiment power consumption to greatly increase, secondly, water bath with thermostatic control work
Need specially there are personnel to be kept an eye on when making, result in the waste of manpower.Moreover, water bath with thermostatic control work when temperature it is unstable
The error of experimental result can be caused.
The content of the invention
The purpose of the present invention is：There is provided a kind of improved high pressure content method gas adsorption instrument coal sample tank, it can significantly drop
Low operation difficulty, saves manpower, financial resources, makes temperature control effect more preferably, existing with regard to technology to overcome the shortcomings of.
What the present invention was realized in：Improved high pressure content method gas adsorption instrument coal sample tank, including tank body, tank body are top
The open column construction in portion, is provided with heat preservation tank in the side wall of tank body, adiabator layer is filled with heat preservation tank, in tank body
Portion is provided with resistive heater and thermistor, and resistive heater is all connected on temperature control device with thermistor；On the top of tank body
Portion is provided with data transfer hole and the baroswitch valve of temp probe provided with being covered on coal sample tank on coal sample tank on lid.
Lid is fixed at the top of tank body by fastening bolt on coal sample tank.
Compared with prior art, resistive heater and thermistor are embedded in coal sample tank body by the present invention, so may be used
To reduce extra equipment auxiliary, and reduce human cost.The demand of different temperatures can be set according to experiment, had
There are fast heating, high insulating effect, temperature stabilization, power saving, saving human resources.The fluctuation pair of temperature can effectively be reduced
The influence of experiment.The present invention is simple in construction, and with low cost, using effect is good.
