Description

Technical Field

[0001] This utility model relates to the field of coal dust suppression, and more specifically, to a coal dust suppression spraying device for coal yards. Background Technology

[0002] Coal dust is a major pollutant generated during coal mining, storage, and transportation. It not only harms the respiratory health of workers but may also cause safety accidents such as dust explosions. It also leads to the waste of coal resources and environmental damage. Therefore, coal dust suppression is a key safety and environmental protection measure in the mining industry.

[0003] In existing technologies, simple water spraying has poor dust suppression effect and short duration. It needs to be used in conjunction with dust suppressants to improve wetting, adhesion or film formation effects. However, the addition of dust suppressants currently relies on manual measurement and mixing, which has problems such as low ratio accuracy and cumbersome operation. Manual addition is easily affected by the intensity of work and experience, resulting in excessively high or low concentration of the agent, which not only affects the dust suppression effect, but also causes waste of agent or equipment corrosion. Moreover, the water pressure of the water pump changes with the working conditions, and manual adjustment cannot be adapted in real time, further reducing the stability of dust suppression. In view of this, we propose a coal dust suppression spraying device for coal yards. Utility Model Content

[0030] Example 2:

[0031] The coal dust suppression spraying device for coal yards provided in Example 1 has been further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the drug addition assembly includes a sliding sleeve 10 for adjusting the inhibitor flow rate. The sliding sleeve 10 is slidably connected inside the pipe 6. An opening 11 is provided on the sliding sleeve 10. A first support rod 12 is fixedly connected to the inner wall of the sliding sleeve 10. A resistance plate 13 for water flow propulsion is fixedly connected to the end of the first support rod 12.

[0033] The usage process of the coal dust suppression spraying device for coal yards provided by this utility model is as follows:

[0034] When suppressing coal dust, an adhesive dust suppressant can be added to the inside of the agent tank 4 and water can be added to the inside of the water tank 2. Then, the water in the water tank 2 is pumped out by the water pump 5 and transported to the pipe 6. When the water enters the inside of the pipe 6, it will hit the resistance plate 13. With the help of the water pressure, the resistance plate 13 will move to the right. When the resistance plate 13 moves, it will drive the sliding sleeve 10 and the sliding rod 14 to move simultaneously. When the sliding rod 14 moves, it will compress the spring 18. When the sliding sleeve 10 moves, the opening 11 on it will gradually align with the transmission pipe 9, so that the agent inside the agent tank 4 can enter the inside of the pipe 6 for mixing. When the water pressure increases, the overlap between the opening 11 and the transmission pipe 9 will be higher, and the amount of agent added will also increase synchronously to achieve synchronous adjustment. At the same time, the remaining water and the amount of agent inside can be observed in real time through the observation window 21 and the scale line 22 for immediate addition.
