Description

Technical Field

[0001] The utility model relates to the technical field of safety explosion-proof devices for coal mine ventilation, and particularly relates to a safety explosion-proof device for coal mine ventilation. Background Technique

[0002] A coal mine refers to a place rich in coal resources, which is generally divided into underground coal mines and surface coal mines. When the coal seam is far from the surface, generally, underground roadways are dug to extract coal, which is an underground coal mine. When the distance between the coal seam and the surface is very close, generally, the surface soil layer is directly stripped to excavate coal, which is a surface coal mine. In order to ensure the safety of workers in the coal mine, ventilation devices are usually used to ensure air circulation.

[0003] However, the traditional safety explosion-proof device for coal mine ventilation has the following disadvantages:

[0004] (1) When ventilation is carried out, if the gas concentration inside the pipeline is too high and combustion and explosion occur, the traditional device has little effect on extinguishing the fire. If the fire inside the pipe is not controlled, it may cause an explosion inside the pipeline, resulting in personal injuries;

[0005] (2) In order to ensure the ventilation effect, fans are usually installed in the rotating device. However, since there are too many impurities in the air inside the coal mine, filters are installed. However, after long-term use, impurities will adhere to the surface of the filter, resulting in poor gas circulation and ventilation effect.

[0006] Therefore, the utility model provides a safety explosion-proof device for coal mine ventilation. Content of the Utility Model

One end of the water extraction pipe 5 penetrates through the ventilation box 1 and is connected through a water collecting pipe 7. Through the settings of the water storage tank 2, the water pump 4, and the water collecting pipe 7, when combustion occurs inside, the power supply of the water pump 4 can be turned on. The water pump 4 pumps out the water inside the water storage tank 2 through the connecting pipe 6, then transmits it to the water extraction pipe 5, and then conveys it to the connecting pipe 6 through the water extraction pipe 5, and then sprays it through the atomizing nozzle 14, thereby achieving the effect of extinguishing fire, and further reducing the problem that the traditional device has little effect on extinguishing fire. A chute is opened on one side of the ventilation box 1, and a slider 8 is slidably connected inside the chute. One end of the slider 8 is fixedly connected with a scraper 9. Through the settings of the slider 8 and the scraper 9, when ventilation is carried out, the filter screen 13 will block some impurities, but too many impurities will block the filter screen 13. At this time, only need to pull the pull block 10 to drive the slider 8 to move, and the slider 8 drives the scraper 9 to scrape the impurities on the surface of the filter screen 13. And even after long-term use, the filter screen 13 may still be blocked. At this time, only need to replace the filter screen 13. Insert the filter screen 13 into the rectangular groove through the set rectangular groove, and then fix it with screws. The other end of the slider 8 is fixedly connected with a pull block 10;

[0033] In the present utility model, the working steps of the device are as follows:

[0034] The first step: Firstly, when combustion occurs inside, the power supply of the water pump 4 can be turned on. The water pump 4 pumps out the water inside the water storage tank 2 through the connecting pipe 6, then transmits it to the water extraction pipe 5, and then conveys it to the connecting pipe 6 through the water extraction pipe 5, and then sprays it through the atomizing nozzle 14.

[0035] The second step: Then, when ventilation is carried out, the filter net 13 will block some impurities, but if there are too many impurities, the filter net 13 will be blocked.
