Description

Technical Field

[0001] The utility model belongs to the technical field of mineral collection, in particular to a coal mine gas extraction and processing device. Background Art

[0002] Coal mine gas extraction and treatment equipment is critical for ensuring coal mine safety and improving resource utilization efficiency. Gas, primarily composed of methane, is flammable, colorless, and odorless, posing a safety hazard. Effective extraction can reduce gas concentrations and mitigate explosion risks. These devices include extraction systems, separation equipment, and monitoring and control systems. While the application of intelligent technology and new materials has improved efficiency, challenges remain in achieving economic viability and integrating the technology. With the energy transition and the development of environmental protection policies, new opportunities are emerging for gas extraction and treatment equipment.

The patent addresses the technical problem of providing a pneumatic frictionless and non-rotating hazardous gas extraction device. The device utilizes its own air duct to create a cyclone in the hood, increasing the suction force within the duct and enabling the extraction function to be completed without an electric motor. The device employs the following technical solutions: a pneumatic coal mine gas treatment device having a hood mounted on the air outlet of the duct, the hood being sealed to the duct, the hood being a trumpet-shaped gradient tube, and a wind grille disposed at the junction of the hood and the duct. The hood has a circumferential array of multiple wind tunnels on its edge, all of which are tilted so that the high-pressure gas exiting the tunnels can form a cyclone. A conical air inlet channel is disposed in the middle of the hood. The device is widely applicable to ventilation and exhaust systems in explosion-proof hazardous areas.

[0004] However, in actual use, this solution operates in a complex environment inside a mine, generating significant amounts of dust as mining operations proceed. This device is unable to filter the dust from the air, which can lead to accelerated wear and clogging of the equipment, reducing efficiency and increasing maintenance costs. Furthermore, dust can affect gas extraction efficiency, increase mine safety risks, cause environmental pollution, and impact the surrounding ecosystem and the health of residents.

[0005] To this end, the utility model provides a coal mine gas extraction and processing device. Utility Model Content

[0028] The locking assembly includes a limiting sleeve 33, and the inner side of the middle end of the limiting sleeve 33 is slidably connected to a uniformly distributed locking ball 34, and the locking ball 34 is limited by the limiting sleeve 33.

An extended range chamber 39 is provided at the inner end of the rear side of the sliding sleeve 36. By providing the extended range chamber 39 on the inner side of the sliding sleeve 36, the distance that the locking ball 34 moves outward is increased. A damping washer 38 is fixedly connected to the rear side of the sliding sleeve 36, and the damping washer 38 is fixed by the sliding sleeve 36.

[0029] A threaded sleeve 3 is fixedly connected to the middle end of the inner rear end of the impeller 21, and the threaded sleeve 3 is fixed by the impeller 21. The threaded sleeve 3 is fixedly connected to the limiting column 31, and the threaded sleeve 3 is threadedly connected to the sliding sleeve 36.
