Description

Technical Field

[0001] The utility model relates to the technical field of dust removal devices, in particular to an environmentally friendly dust removal device used for open-pit coal mining. Background Art

[0002] Existing open-pit mining, also known as open-pit mining, is a process of removing the covering on the ore body to obtain the required minerals, and the process of extracting useful minerals from the open surface mining site. Coal mines are mining areas rich in coal. When the coal seam is very close to the surface, it is generally chosen to directly strip off the surface soil layer to excavate the coal. This is an open-pit coal mine.

[0003] A large amount of dust will be generated during coal mining, which will not only pollute the environment, but also affect the health of workers and production safety. For the sake of environmental protection and the health of workers, dust removal devices are used for dust removal during the mining process. The fog cannon uses a high-pressure fan to spray water into mist particles, and uses instantaneous oscillation diffusion technology to adsorb and fix dust particles on the mist water droplets, thereby achieving the effect of dust removal.

[0004] When the fog cannon is transported to a coal mine, due to the complex environment of the coal mine, its external nozzle collides with other objects during transportation, causing the nozzle to be damaged, thereby affecting its normal operation. Utility Model Content

[0027] Working principle:

[0028] In the first step, when the dust removal device is not used temporarily, the two ends of the protective tube 2 are slidably connected to the outside of the connecting plate 7 through the installation groove 4, and the limiting bolt 6 is rotated to make the limiting bolt 6 fit with the outside of the connecting plate 7 located inside the installation groove 4. At this time, the protective tube 2 is installed, and the protective tube 2 covers the nozzle 15 outside the dust removal device;

[0029] The second step is to set the cover plate 3 in conjunction with the partition plate 11. When the dust removal device is used, if there is a lot of flying dust and stones in the environment where the dust removal device is located, the cover plate 3 is rotated to release the connection between the cover plate 3 and the protective tube 2. At this time, the partition plate 11 is exposed. At this time, the placement plate 12 is pulled, and the spring 14 is exposed. At this time, the handle 10 is sleeved on the outside of the placement plate 12. At this time, the cover plate 3 is placed. At this time, the placement plate 12 is released. Under the action of the spring 14, the placement plate 12 moves to clamp the cover plate 3 on the outside of the body 1. When the dust removal device is working, the partition plate 11 can provide certain protection for the nozzle 15 of the dust removal device, thereby reducing the probability of damage to the nozzle 15 by flying dust and stones.
