Description

Improved generation coal sample jar

Technical Field

The utility model relates to an improved generation coal sample jar belongs to coal sample storage, shifts and detection area.

Background

In the gas assay in-process, coal sample jar belongs to the equipment of an indispensable coal sample, and coal sample jar air inlet is all installed on the cover, directly leads to the sealed degree of difficulty of coal sample jar to increase, if increaseing after the coal sample of packing into screws up the cover, probably leads to the cover damage, the coal sample jar condition such as scrap, if do not increase and screw up the cover, lead to gas leakage again easily, can not add the jar mouth with the gasket again and make its increase leakproofness, because can influence the measured data. And under current condition, after measuring gas content on the spot in the pit, the coal sample jar is because the volume is great again, and weight is heavier, and the can body carries also to be a big difficult problem, has increased personnel's health burden, has reduced the actual efficiency of measuring gas, takes the coal sample jar to the in-process in the laboratory in the pit from the pit, because the transport is not smooth, seals not tight, produces gas leakage circumstances such as easily, leads to influencing the laboratory and further measures gas content. In view of the above, there is a need for a new and improved coal sample tank that solves the above problems.

Disclosure of Invention

The utility model provides an improved generation coal sample jar to it is unreasonable to solve current coal sample jar structural design, and sealed the degree of difficulty is big, causes damage or gas leakage easily when the cover is screwed up, and is difficult for carrying inconvenient problem.

For solving above-mentioned problem, plan to adopt such improved generation coal sample jar, including a jar body, the upper end of jar body has the jar mouth that is equipped with the external screw thread outward, and jar mouth top spin is equipped with the cover, and the department cladding of the last port department of jar mouth has one deck rubber gasket, and the air duct has still been drawn forth to the upper end of jar body, is provided with the valve on the air duct, and the detection mouth is connected to the outer end of air duct, and the bottom of jar body sets up the walking wheel.

In the aforesaid coal sample jar, the inboard of jar mouth still is provided with the crisscross iron wire to it is internal to avoid the rubber gasket to fall into the jar.

In the coal sample tank, a crossed iron wire is arranged on the lower side of a tank opening at the upper end of the tank body so as to prevent the rubber gasket from falling into the tank body;

in the aforesaid coal sample jar, the middle part cover of the jar body is equipped with the adapter sleeve, and one side of adapter sleeve is connected with the telescopic link through the connecting axle, is provided with the handle on the other end of telescopic link.

Compared with the prior art, the utility model separates the tank opening from the air duct for detection, the gas in the coal sample tank can not reach the gas outlet from the original tank opening, the gas can be directly discharged from the gas outlet to measure the gas pressure, and the problem that the original coal sample tank can not strengthen the sealing gas because the gas needs to be measured is solved, so that the coal sample tank can not only ensure the accuracy of gas measurement, but also strengthen the sealing of the gas; can be when carrying out gas content measurement, increase jar mouth leakproofness, prevent that it from appearing the loss in the survey process, and then guarantee the accuracy and the reliability of testing result, simultaneously, can also guarantee that gas can discharge smoothly to the survey equipment through the air duct, the back that finishes of survey, because the leakproofness of jar mouth position is strengthened, arrive the in-process gas in laboratory after going out of the well and can not take place too much loss, guaranteed that the laboratory can carry out further processing to gas smoothly, the walking wheel has been added again, the telescopic link, equipment such as handle, facilitate for the difficult portability of coal sample jar itself, the problem is carried to solution measurement personnel's that can be very big, it is heavier to have solved original coal sample jar weight, inconvenient removal, personnel move the time too much, the problem that measurement of efficiency descends.

Fig. 1 is a schematic structural view of the present invention;

fig. 2 is an enlarged partial top view of the can mouth of fig. 1.

Detailed Description

To further clarify the objects, technical solutions and advantages of the present invention, a more particular description of the invention will be rendered by reference to the appended drawings, which are illustrated in the appended drawings.

Examples

Referring to fig. 1 and 2, this embodiment provides an improved generation coal sample jar, including a jar body 9, the upper end of jar body 9 has jar mouth 13 that is equipped with the external screw thread outward, jar mouth 13 top spin is equipped with cover 4, and the upper port department cladding of jar mouth 13 has one deck rubber gasket 5, air duct 2 has still been drawn forth to the upper end of jar body 9, be provided with valve 3 on the air duct 2, detection mouth 1 is connected to the outer end of air duct 2, the bottom of jar body 9 sets up walking wheel 10, the inboard of jar mouth 13 still is provided with criss-cross iron wire 12, in order to avoid rubber gasket 5 to fall into jar body 9, the middle part cover of jar body 9 is equipped with adapter sleeve 8, one side of adapter sleeve 8 is connected with telescopic link 11 through connecting axle 7, be.

The valve 3 is arranged at the upper part of the air duct 2 and is an air guide valve, and the telescopic rod 11 and the handle 6 thereof are arranged at the left area position in the middle of the tank body 9.

The specific implementation mode is as follows: after the detection personnel arrive in the pit, put coal sample jar on the plane in the pit, screw up valve 3 through the handle, open cover 4, then collect the coal sample, pack it into the coal sample jar fast, then put jar mouth 13 upper end with rubber gasket 5, rubber gasket 5 can not fall into jar 9 because of the existence of iron wire 12 in, cover 4, screw up cover 4, at this moment, the gas is sealed up and is deposited in jar 9, does not communicate with each other with the external world. Then link to each other with external analytic appearance rubber tube through detecting mouth 1, open valve 3, gas is drawn forth through air duct 2 and is measured, measures the back that finishes, screws up the handle, closes valve 3, then pulls open telescopic link 11, holds handle 6 tightly and holds and transports out the well with coal sample jar support through runner 10, sends to the laboratory and carries out further analysis and processing.

The utility model discloses can be when carrying out gas content measurement, increase jar mouth leakproofness, prevent that its loss from appearing in the survey process, and then guarantee the accuracy and the reliability of testing result, simultaneously, can also guarantee that gas can discharge smoothly to the measuring equipment through air duct 2, the back that finishes is surveyed, because the leakproofness of jar mouth 13 position is strengthened, too much loss can not take place for the in-process gas that reachs the laboratory after going out of the well, guaranteed that the laboratory can carry out further processing to gas smoothly. The walking wheels 10, the telescopic rods 11, the handle 6 and other devices are added, convenience is brought to the portability of the coal sample tank, the problem of equipment conveying of measuring personnel can be greatly solved, and the problems that the original coal sample tank is heavy in weight, inconvenient to move, too much in personnel moving time and low in measuring efficiency are solved.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
