Description

Technical Field

[0001] This application relates to the technical field of safety protection in coal mine mining, and in particular, to a device for comprehensively preventing accidents of ventilation, fire prevention, dust prevention, and gas prevention in the coal mining face. Background Art

[0002] "One ventilation and three preventions" in underground coal mines is one of the important measures to ensure the safe production of coal mines, mainly including four key links: ventilation, fire prevention, dust prevention, and gas prevention. As the core part of it, ventilation can not only ensure the oxygen supply for underground workers by introducing fresh air from the surface into the mine, but also effectively dilute and discharge harmful gases in the mine, providing a safe environment for mine operations. With the increase in coal mining depth and technological progress, higher requirements are put forward for the reliability, safety, and environmental protection of the ventilation system, and its role in coal mine safety production becomes increasingly important.

[0003] Under the related technology, in order to improve the ventilation quality of the mine, various means are usually adopted for air treatment. For example, a filter screen is set at the inlet of the ventilation duct to block large particle impurities, or electrostatic adsorption technology is used to remove tiny particles in the air. In addition, to prevent dust from accumulating on the inner wall of the ventilation duct, some devices are also equipped with mechanical scraping or air flow purging functions. At the same time, in order to monitor the air quality in the mine, gas detection equipment is usually installed at the outlet of the ventilation duct to detect the concentrations of gases such as gas, oxygen, and carbon dioxide in real time. These means have improved the safety and efficiency of mine ventilation to a certain extent.

[0004] In view of the above related technology, there are still deficiencies in the filtration and cleaning of the ventilation system. Specifically, the air filtration effect is not ideal enough, especially for the air containing a large amount of coal dust above the mine, it is difficult to achieve efficient purification; at the same time, the side walls of the device are prone to adhesion of dust. If not removed in time, the dust on the side walls of the device is blown into the ventilation duct, which will further affect the ventilation efficiency and air quality, and thus pose a potential threat to the physical health of underground workers.

The air is filtered by the air holes 21 of the filter plate 2 and passes through the air holes 21, and the filtered air is discharged through the exhaust pipe 12. When it is necessary to clean the dust on the filter plate 2 and the inner wall of the device housing 1, start the motor 42 to drive the first screw rod 41 to rotate, drive the first cleaning plate 31 to slide towards the side close to the first receiving groove 22 along the second direction, and at the same time drive the collecting member 32 to slide along the first direction through the first bevel gear 61, the second bevel gear 62 and the second screw rod 63, and the second cleaning plate 323 cleans the dust on the side wall of the device housing 1; The second screw rod 63 continues to drive the collection member 32 to slide, and the collection member 32 will drive the filter plate 2 to slide towards the exhaust pipe 12. When the second screw rod 63 rotates to drive the collection member 32 to slide away from the filter plate 2 along the first direction, under the action of the first elastic member 73, the filter plate 2 will reset. During this process, the filter plate 2 shakes to shake off the dust in the air holes 21 and reduce the occurrence of blockage of the air holes 21.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
