Abstract
The utility model relates to a coal sample collection tank for gas content measurement. The coal sample collection tank comprises a stainless steel tank cap (1) and a tank body (2), and is characterized in that a chassis of the tank body is uniformly provided with four stainless steel micro-seam slim sieve tubes (4) which extend to the upper part of the tank body. According to the utility model, because the tank body is internally provided with the sieve tubes (4), the gas desorbed from a coal sample positioned at the bottom of the tank body is easier to emit through the sieve tubes (4), the time of a gas content measuring experiment is greatly shortened; the measuring result is accurate.
Description
Technical field
The utility model relates to a kind of coal sample for gas bearing capacity mensuration and gathers jar.
Background technology
It is requisite work in coal mining enterprise's safety in production that gas bearing capacity is measured, be present the most frequently used method by measuring after the coal sample collection jar samples of coal pulled, there is following shortcoming in existing coal sample collection jar: after tank body is filled coal sample, because the top coal sample overstocks, the methane gas of the coal sample solution sucking-off of bottom can not be distributed to tank body top as early as possible, cause tank base gas density height, desorption of mash gas speed is slow, and measurement result is inaccurate in the limited time.
Summary of the invention
Advantages such as the purpose of this utility model is the shortcoming that overcomes prior art, provides a kind of coal sample for gas bearing capacity mensuration to gather jar, and has the minute weak point, and measurement result is accurate.
The utility model is to solve the problems of the technologies described above the technical scheme that adopts to be: a kind of coal sample for gas bearing capacity mensuration is gathered jar, formed by stainless tank body, cover, be provided with four stainless steel slit dusting cover pipes that extend tank body top on the tank body chassis uniformly.
Effect of the present utility model is: four stainless steel slit dusting cover pipes that extend tank body top that arrange uniformly on the tank body chassis, after tank body is filled coal sample, the Device in Gas physical efficiency of the coal sample solution sucking-off of bottom is distributed to tank body top fast, and derive by the gas vent on the cover, the gas bearing capacity determination experiment time shortens, and measurement result is more accurate.
Description of drawings:
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Accompanying drawing 1 is the utility model one-piece construction synoptic diagram.
Accompanying drawing 2 is the utility model tank interior structural representations.
Among the figure: 1-cover, 2-tank body, 3-gas vent, 4-screen casing.
Embodiment:
Now the utility model is described in further detail by reference to the accompanying drawings.
A kind of coal sample for gas bearing capacity mensuration is gathered jar, formed by stainless cover (1), tank body (2), be provided with four stainless steel slit dusting cover pipes (4) that extend tank body top on tank body (2) chassis uniformly, after gathering full coal sample in the tank body, the gas of the coal sample desorb of tank base can enter stainless steel slit dusting cover pipe (4) rapidly, and derives by the gas vent (3) on the cover (1).Stainless steel slit dusting cover pipe (4) in the utility model can be Any shape.
Claims (1)
1. claim item 1 refers to a kind of coal sample collection jar for gas bearing capacity mensuration, comprise stainless cover (1), tank body (2), it is characterized in that: be provided with four stainless steel dusting cover pipes (4) that extend tank body top on described tank body (2) chassis uniformly.
