Description

A sealed preparation table

Technical Field

The utility model relates to the technical field of gas-containing coal sample preparation, in particular to a sealed preparation table.

Background technique

As the demand for deep mining increases, the possibility and complexity of dynamic disasters in the mining process also increase. Single dynamic disasters such as coal and gas outbursts and rock bursts occur during the mining process. These two dynamic disasters are compounded with the increase of mining depth. The mechanism of compound dynamic disasters is more complicated than that of single dynamic disasters, and the consequences will be more serious. In the prevention and control experiment of compound dynamic disasters, a preparation device is needed to prepare gas-containing coal samples.

However, after the traditional experimental preparation device completes the preparation of the gas-containing coal sample, the prepared gas-containing coal sample will come into contact with the air to cause gas escape, which will cause subsequent experimental errors and is not conducive to use. For this reason, we propose a sealed preparation table.

The utility model provides a sealed preparation table. When in use, first check the air tightness of the whole device. After the check, remove the top plate 7 and place the coal sample in the center of the circular operating table 8. At the same time, place the silicone liquid bottle 10 filled with silicone liquid in the placement place. After the operation is completed, cover the top plate 7 completely and seal it with a silicone sticker. Open valve 15 and valve 26 to keep the high-pressure gas bottle 2 in a closed state, open the vacuum pump 1 to perform vacuum treatment on the whole device, observe the readings of pressure gauge 13 and pressure gauge 24, close valve 15 after the vacuum treatment is completed, keep valve 26 in an open state, open the high-pressure gas bottle 2 for inflation, observe the reading of pressure gauge 24, and close the high-pressure gas bottle 2 and valve 26 when the predetermined value is reached. Keep the test device stable, and open valve 26 and high-pressure gas bottle 2 again to replenish gas by observing the pressure gauge 13 until the reading is lower than the preset value, and continue to close valve 26 and high-pressure gas bottle 2 when the pressure gauge 24 reaches the preset value. After the reciprocating device is stationary for 6 hours, the reading of pressure gauge 13 still maintains the preset value, indicating that the preparation of gas-containing coal sample is complete. After the coal sample is prepared, the silica gel in the silica gel bottle 10 built in the box is used to smear the coal sample to isolate the coal sample from the gas exchange with the outside world. After the preparation is completed, the triaxial test can be carried out directly. If it needs to be stored, it can be taken out from the top plate 7 and stored in a constant pressure gas container with the same gas pressure.
