Description

Technical Field

[0001] This utility model relates to the field of gas extraction technology, specifically to an inclined deep-hole large-diameter gas extraction device. Background Technology

[0002] In recent years, with the continuous advancement of coal mining technology and the increase in mining depth, the threat of coal mine gas disasters has become increasingly prominent. Therefore, it is necessary to use gas extraction devices to extract gas from inside the mine.

[0003] Mine gas typically has a relatively high concentration because the gas released from underground mining activities accumulates in enclosed spaces. Directly discharging the extracted gas can easily pollute the environment and also pose certain safety hazards. Utility Model Content

[0004] The purpose of this invention is to provide an inclined deep-hole large-diameter gas extraction device, which has the advantage of mixing external air with the extracted gas during gas extraction to reduce the gas concentration, thus solving the problems of high extracted gas concentration, easy environmental pollution, and safety impact.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an inclined deep-hole large-diameter gas extraction device, comprising a housing and a filter screen. A pump body is installed at the bottom of the housing, a connecting rod is movably installed on one side of the housing, and a housing is embedded in the other side of the housing. A movable rod is movably installed inside the housing, and fan blades are installed in a circular array on the outer side of a section of the movable rod extending into the housing. A pump body is installed at the bottom of the housing, and a fixed rod is movably installed on the pump body. A connecting pipe is embedded in the top of the housing, and an insertion hole is opened on the side of the connecting pipe. The filter screen is inserted into the connecting pipe through the insertion hole.

[0006] When using the inclined deep-hole large-diameter gas extraction device in this technical solution, the fixing frame is fixed to the bearing structure through the fixing holes of the fixing frame using bolts and other tools. The fixing frame fixes the box body. The suction pipe at the bottom of the pump body is connected to the exhaust pipe inside the mine. The motor drives the connecting rod to rotate through the transmission structure. The connecting rod drives the fixing rod to rotate through belt one. When the fixing rod rotates, it drives the turbine blades to rotate. When the turbine blades rotate, they generate suction. The pump body draws in the gas inside the mine through the suction pipe and then transports the gas into the box body through the exhaust pipe. The fixing rod drives the movable rod to rotate through belt two. The movable rod drives the fan blades to rotate. The fan blades transport the air inside the shell into the box body. The connecting rod drives the stirring rod to rotate. The stirring rod mixes the gas and air inside the box body. The gas inside the box body is discharged from the connecting pipe. The filter screen inside the connecting pipe adsorbs impurities in the gas.

[0007] Preferably, a motor is installed on the side of the housing away from the outer shell, and the motor transmission structure is fixedly connected to the connecting rod. The motor can drive the connecting rod to rotate through the transmission structure.

[0008] Preferably, the fixed rod is located inside the pump body, with turbine blades arranged in a circular array on its outer side. An air intake pipe is embedded at the bottom of the pump body, and an air outlet pipe is installed at the top of the pump body. When the fixed rod rotates, it drives the turbine blades to rotate, and the rotation of the turbine blades generates suction. The pump body draws in methane gas from inside the mine through the air intake pipe and then discharges it through the air outlet pipe.

[0009] Preferably, the top of the vent pipe extends into the interior of the housing. The vent pipe delivers gas into the interior of the housing.

[0010] Preferably, a stirring rod is installed in a circular array on the outer side of a section of the connecting rod extending into the housing. The stirring rod can mix the gas and air inside the housing.

[0011] Preferably, the connecting rod is movably connected to the fixed rod via belt one, and the fixed rod is movably connected to the movable rod via belt two. When the connecting rod rotates, it drives the fixed rod to rotate via belt one, and the fixed rod drives the movable rod to rotate via belt two.

[0012] Preferably, a fixing frame is welded to the front side of the housing, and the fixing frame has fixing holes arranged in a rectangular array. Using bolts or other tools, the fixing frame is fixed to the load-bearing structure through the fixing holes, thus securing the housing.

[0013] Preferably, a fixing groove is provided on the inner side of the connecting pipe, and the side of the filter screen inserted into the connecting pipe is inserted into the fixing groove. The fixing groove fixes the filter screen inside the connecting pipe, preventing the filter screen from shaking when filtering air.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention utilizes a fan blade and a stirring rod. A connecting rod drives a fixed rod to rotate via a belt, which in turn drives a turbine blade. The turbine blade generates suction, drawing in methane gas from the mine through a suction pipe and then delivering it to the housing through an outlet pipe. The fixed rod drives a movable rod to rotate via a belt, which in turn drives the fan blade, which in turn delivers air from inside the housing to the housing. The connecting rod drives the stirring rod to rotate, mixing the methane gas and air inside the housing. The gas inside the housing is then discharged through a connecting pipe, where a filter absorbs impurities. This design achieves the effect of mixing external air with the extracted methane gas during extraction, thereby reducing the methane concentration. Attached Figure Description
