Description

Technical Field

[0001] The utility model relates to the technical field of underground slag water discharge in coal mines, in particular to an integrated device for timing slag water discharge in mines. Background Art

[0002] During the gas extraction process in coal mines, a large amount of condensed water is formed in the pipelines of the extraction system due to the large temperature changes at various locations underground in the coal mine. In addition, due to the water content in the sandstone fissure water and the coal seam, a large amount of borehole water will be extracted during drilling extraction. This will affect the normal operation of the extraction system, increase the extraction resistance, and reduce the extraction effect, which is manifested as an increase in the negative pressure of the system, a decrease in the pressure difference, and an illusion of increased concentration. Therefore, water accumulation in the extraction system has become a major safety hazard that affects the stability of the system. Some existing mine slag water discharge devices generally discharge slag water together during the slag water discharge process, and other equipment is required to perform secondary separation of the slag water, which affects the construction efficiency.

The first air-controlled valve is respectively connected to a first buffer tank and a second buffer tank, and the first buffer tank is connected to the first butterfly valve through the second air-controlled valve. The air in the air supply pipe is set to enter the first buffer tank through the first air-controlled valve. When the air pressure in the first buffer tank reaches a threshold value, the first buffer tank opens the first butterfly valve through the second air-controlled valve to discharge the slag water in the pre-pumping tank into the separation discharge tank for separation. At the same time, the first air-controlled valve switches from supplying air to the first buffer tank to supplying air to the second buffer tank. When the second buffer tank reaches the air pressure threshold, the first butterfly valve is closed, and the second buffer tank opens the second butterfly valve through the third air-controlled valve to discharge the water in the water cavity. The first air-controlled valve switches from supplying air to the second buffer tank to supplying air to the first buffer tank, thereby achieving the effect of cyclic timing slag discharge.

By setting up the negative pressure pipe, the mine can be pumped under negative pressure to reduce safety hazards.
