Description

Technical Field

[0001] The utility model relates to the technical field of cooling and dust removal devices, in particular to a cooling and dust removal device for a coal mine excavation working face. Background Art

[0002] In coal mining working faces, due to the continuous mining of underground coal seams and mechanical operations, a large amount of heat and dust will be generated on the working face. These heat and dust not only seriously affect the comfort of the working environment, but also pose a serious threat to the health and safety of workers. Cooling and dust removal devices are usually used in places where the air quality of the working environment needs to be improved, such as coal mining working faces, factory workshops, construction sites, etc.

[0003] The coal mine mining face cooling and dust removal device described in the comparative document (publication number: CN220203946U) realizes the functions of dust suction, cooling and dust removal through the combination of components such as a mobile base, a fixed box, a dust removal box, a storage box and an installation box. However, there are still some problems with poor treatment effects in actual applications. Specifically, the device still needs to be improved in terms of dust removal efficiency and cooling effects. In terms of dust removal efficiency, due to the high dust concentration and wide particle size distribution of the coal mine mining face, traditional dust suction and dust removal methods are often difficult to completely capture and effectively process all dust particles, resulting in unsatisfactory dust removal effects. In addition, as the operation time increases, the amount of dust accumulated in the dust removal box gradually increases. If it is not cleaned in time, it will also affect the dust removal efficiency and the normal operation of the equipment. In terms of cooling effect, although the device sprays water mist through water pipes and nozzles to lower the air temperature, factors such as the coverage, uniformity and duration of the water mist will affect the cooling effect. At the same time, in a high temperature and high humidity environment, the evaporation rate of the water mist is accelerated, which may cause excessive humidity, thereby affecting the comfort of the working environment. Utility Model Content

[0016] The bottoms of the two drainage pipes 7 are connected to the tops of water collecting plates 1 5 and 2 6 respectively, ensuring that the water in the water tank 4 can be evenly and quickly distributed to the two water collecting plates, and then evenly sprayed onto the working surface through nozzles 1 8 and 2 9, effectively achieving the effects of cooling and dust removal.

[0017] A screen is fixedly installed on one side of the dust collector head 14, which can effectively filter large particles of impurities in the inhaled air.

The screen in the dust suction head 14 filters out large particles of impurities in the air and then sucks the dust into the dust exhaust pipe 15. The dust in the dust exhaust pipe 15 enters the dust collecting box 17 through the connecting pipe 16, and is captured and collected by the rotating adsorption mesh plate 19. Finally, the dust in the dust collecting box 17 can be cleaned out by opening the movable sealing plate 20.
