Description

Technical Field

[0001] This invention relates to the field of coal mining, and more particularly to a coal mine gas adsorption device. Background Technology

[0002] A coal mine is an area where humans extract coal resources in coal-rich areas. It is generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, underground tunnels are typically dug to extract the coal; this is an underground coal mine. When the coal seam is very close to the surface, the surface soil is typically stripped away to extract the coal; this is an open-pit coal mine. The vast majority of coal mines in my country are underground mines. A coal mine encompasses a large area, including both above-ground and underground areas, as well as related facilities. A coal mine is a rationally excavated space created by humans when mining coal-rich geological strata, typically including tunnels, shafts, and mining faces. During coal mining operations, large amounts of methane gas may be generated. If the ventilation in the tunnels is poor, methane gas may accumulate, potentially leading to explosions and increasing safety hazards. Summary of the Invention

[0024] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings. This description is intended only to illustrate specific embodiments of the invention and does not constitute any limitation on the invention. The scope of protection of the invention is defined by the claims.

The storage device 6 is movably placed in the hollow position of the support mechanism and the ground of the storage device 6 is in contact with the base plate 1.

[0028] The gas drawn in by the main adsorption mechanism or the auxiliary adsorption mechanism is filtered by the filtration mechanism and then output to the water ring vacuum pump 9. The water ring vacuum pump 9 then filters the gas again and outputs it to the storage device 6.

[0029] Optionally, a secondary adsorption mechanism is provided on the top surface of the box 11, and a primary adsorption mechanism is provided on the front surface of the box 11. The primary adsorption mechanism can effectively adsorb gas in the large environment, thereby effectively improving work efficiency. The secondary adsorption mechanism can effectively adsorb gas in a smaller environmental area, thereby effectively preventing gas residue.

[0030] Optionally, a box 11 is fixedly connected to the top surface of the base plate 1. A connecting pipe 31 with a flange is provided between the box 11 and the air inlet pipe 10. A filter mechanism is provided in the box 11. The filter mechanism can effectively filter impurities such as coal ash in the air, thereby effectively ensuring the quality of gas and facilitating the subsequent recycling and reuse of gas.

[0031] Optionally, a water ring vacuum pump 9 is installed on the base plate 1. The water ring vacuum pump 9 is detachably connected to the base plate 1 by bolts. The water ring vacuum pump 9 includes an outlet pipe 8 and an inlet pipe 10. A high-pressure connecting hose 7 with a flange is installed between the outlet pipe 8 and a set of storage tanks 6. The water ring vacuum pump 9 can effectively and conveniently introduce gas into the storage tanks 6. At the same time, due to the characteristics of the water ring vacuum pump 9, it can effectively prevent gas leakage and thus effectively improve safety.

[0032] Optionally, each storage device 6 (which can be a storage tank) is equipped with a storage tank valve 5 that is movably connected. The storage tank valve 5 can effectively facilitate the opening and closing of the storage device 6, thereby facilitating the export or import of gas.

[0033] Optionally, a support mechanism is provided on the base plate 1, and four sets of storage tanks 6 (a type of storage device) are provided on the support mechanism. The four sets of storage tanks 6 are movably connected to the support mechanism, and the bottom surfaces of the four sets of storage tanks 6 are in contact with the base plate 1.

[0034] The operation of a coal mine gas adsorption device follows these steps:

[0035] S1: When in use, the water ring vacuum pump 9 works, and then the main adsorption mechanism introduces the gas and coal ash in the mine into the box 11, and then filters them through the filtration mechanism, thereby effectively ensuring the quality of the stored gas.

[0036] S2: When gas and coal ash enter the housing 11, the gas and coal ash are brought into the dust removal device of the water ring vacuum pump 9 by the action of the water ring vacuum pump 9, thereby effectively filtering the coal ash.

[0037] S3: When adsorbing methane in a smaller environment, the methane and coal ash in the mine are introduced into the box 11 through the secondary adsorption mechanism and then stored in the storage tank 6.

The secondary adsorption mechanism can effectively adsorb gas in smaller areas, further improving the convenience of gas adsorption and thus increasing work efficiency. The water ring vacuum pump effectively introduces external gas into the storage tank. Due to the pump's performance, it effectively prevents gas explosions. The filter mechanism within the housing effectively filters out impurities such as coal ash, ensuring gas quality and facilitating subsequent recycling and reuse. The supporting mechanism effectively supports the four storage tanks, ensuring their stability during gas adsorption and thus improving safety.

The four tanks also allow for greater methane storage, facilitating later recycling. A water-ring vacuum pump effectively draws external methane into the tanks, preventing explosions. A filter system effectively removes impurities like coal ash, ensuring methane quality and facilitating recycling. The main adsorption mechanism effectively adsorbs large amounts of methane in the tunnel, improving efficiency, while the secondary adsorption mechanism effectively adsorbs smaller areas, enhancing the ease of methane adsorption and further improving overall efficiency.
