Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust treatment technology, specifically to an underground dust collection and purification device. Background Technology
[0002] Underground dust collection and purification equipment is a crucial device used in mining and underground engineering construction to improve air quality and protect the health of workers. Traditional equipment often suffers from low collection efficiency, poor purification effect, and difficulty adapting to the complex underground environment, failing to meet the stringent requirements of modern mining for underground working conditions. With increasing emphasis on occupational health and environmental protection, there is an urgent need for a highly efficient, compact, and adaptable underground dust collection and purification system to effectively reduce dust concentration, improve the underground working environment, and safeguard the health of miners.
[0003] Patent publication number CN218306882U discloses a dust treatment device for underground mines, including a dust collection box, an exhaust chamber opened on one side of the dust collection box, and a water tank opened inside the dust collection box. A rotating roller is rotatably connected to the middle of the water tank. A circularly distributed filter water cloth is fixed on the outer wall of the rotating roller. The outer walls of the filter water cloth slide against the inner walls of the water tank on both sides.
[0004] To address the persistent problem of dust accumulation, existing technology involves starting a drive motor and water pump during operation. The drive motor rotates the exhaust fan blades, drawing air into the exhaust chamber, which then enters a water tank. Guided by a baffle, the air is blown upwards and impacts the outer surface of a dust-filtering cloth. Dust particles in the air are filtered by the cloth, which is continuously replenished to the top of the water tank via rotating rollers. The filtered air is then expelled from the outlet by airflow from the rear. However, this method still results in some small dust particles remaining, making large-scale dust collection difficult and potentially causing health problems for construction workers.
