The portable jaw crusher and the coal sample tank are respectively connected with the gas desorption test device through the gas guide tube. The device can be conveniently carried by field researchers and technicians of coal enterprises to carry out work smoothly in the field. The coal sample is directly crushed and desorbed, and the gas amount of the coal sample which cannot be desorbed under normal pressure can be timely and conveniently tested, so that the contact time of extracted coal sample and air is shortened, and the precision of the content test result of total gas in the coal sample is improved.

Description

Portable down-hole desorb/pulverizing desorb integrated apparatus
Technical field
The utility model relates to the on-the-spot desorb integrated apparatus of pulverizing of coal sample gas, specifically be on the basis of the large-scale pulverizing desorption apparatus that forefathers develop, coal sample to coal mine work area (coal road) extraction is carried out site desorption, test coal sample normal pressure can not desorbing mash gas content a kind of portable down-hole desorb/pulverizing desorb integrated apparatus, be applicable to each big coal universities and colleges and each big coal enterprise.
Background technology
The generation of the outstanding disaster of coal and gas has become the one of the main reasons of restriction coal in China career development, and the further investigation of coal and gas outburst mechanism is had very important meaning to the coal in China industrial expansion.Measuring coal seam gas-bearing capacity accurately, is the outstanding key of control coal and gas.Present employed gas bearing capacity determinator can't carry out the scene in the down-hole and pulverize, can only utilize the coal sample jar that institute's coal sampling is taken to ground, carry out the pulverizing desorb of coal sample, coal sample jar gas leak phenomenon may appear in this process, make coal sample in being taken to the process on ground, contact with oxygen for a long time, coal oxygen recombination reaction takes place, caused the structural damage of coal sample, cause to measure accurately the gas bearing capacity of desorb in the nature desorb of coal sample ground and the crushing process, make test result and actual gas bearing capacity very large deviation occur, can't be in the produced on-site process coal and gas outburst prevention treatment work effectively being instructed.
Summary of the invention
The purpose of this utility model provides a kind of portable down-hole desorb/pulverizing desorb integrated apparatus.
The utility model is to adopt following technical scheme to realize: a kind of portable down-hole desorb/pulverizing desorb integrated apparatus, comprise coal sample harvester, small-sized coal sample reducing mechanism, data acquisition and analytical equipment, described coal sample harvester is made up of hand drill, twist drill rods, coal sample jar (5); Small-sized coal sample reducing mechanism is made up of portable jaw crusher (4), wireway (3), mechanical stopwatch (2); Data acquisition and analytical equipment are made up of methane gas desorption quantity proving installation (1) and computing machine (6), and portable jaw crusher (4) is connected with methane gas desorption quantity proving installation (1) by wireway (3) respectively with coal sample jar (5).
The utility model is on the basis of the remaining content measuring device of large-scale coal sample gas of forefathers' development, changed that former machine volume is big, weight is big, carry deficiency such as inconvenience, has developed a portable down-hole desorb/pulverizing desorb integrated apparatus that the cover volume is little, in light weight, easy to carry, the scene is practical, the test result precision is high.The utility model can make things convenient for on-the-spot scientific research personnel and the technician of coal enterprise to carry and operate, carry out the work smoothly at the scene, institute's coal sampling is directly pulverized desorb, test timely and conveniently under the coal sample normal pressure can not coal seams gas discharging quantity, reduce the duration of contact of extraction coal sample and air, improved the precision of the overall gas bearing capacity measurement result of coal sample, the utility model measuring effect is clear directly perceived, short, the instant effect of sense cycle is for the mensuration of coal body gas bearing capacity provides convenience.Can be that the gas bearing rule provides basic data in the further research coal seam.The utility model has reduced coal sample in the process of transporting because the poorly sealed close big problem of experimental data deviation that causes also reduces experimentation cost simultaneously.
Description of drawings
Accompanying drawing is structural representation of the present utility model.
Embodiment
A kind of portable down-hole desorb/pulverizing desorb integrated apparatus comprises coal sample harvester, small-sized coal sample reducing mechanism, data acquisition and analytical equipment, and the coal sample harvester is made up of hand drill, twist drill rods, coal sample jar 5; Small-sized coal sample reducing mechanism is made up of portable jaw crusher 4, wireway 3, mechanical stopwatch 2; Data acquisition and analytical equipment are made up of methane gas desorption quantity proving installation 1 and computing machine 6, and portable jaw crusher 4 is connected with methane gas desorption quantity proving installation 1 by wireway 3 respectively with coal sample jar 5.
The concrete experiment method of the utility model is as follows: before the experiment beginning, detect installing impermeability own earlier, after determining that the device impermeability is good, the VI class coal sample of the good seal that utilizes the coal sample harvester to collect is connected with coal sample methane gas desorption quantity proving installation 1, in the down-hole coal sample gas bearing capacity of gathering is directly measured, afterwards coal sample jar 5 is sealed fully, bring to ground, it is connected again with coal sample methane gas desorption quantity proving installation 1, open coal sample jar 5 valves, measure the direct desorption quantity in coal sample ground, (specifically decide on the desorb situation behind the desorb 40min, if long-time no gas occurs stopping desorb, end of record reading) opens coal sample jar 5, wherein coal sample is taken out and is utilized 60~80 purposes combination sieve, it is sieved, taking-up 120g pours in the portable jaw crusher 4 and with it and is connected with methane gas desorption quantity proving installation 1, gas amount that can not desorb under the coal body normal pressure in the test crushing process, utilize desorption of mash gas amount of mechanical stopwatch 2 every 30s records in the crushing process, by the analysis to data, thereby draw under institute's coal sampling normal pressure can not desorb gas bearing capacity, for gas bearing rule in the research coal seam provides basic data.
