Description

Technical Field

[0001] This utility model relates to the field of coal storage yard technology, specifically to a spray dust suppression device for open-air coal storage yards. Background Technology

[0002] Coal storage yards are areas used to store coal, with the primary purpose of ensuring the stability and security of coal supply. The main function of coal storage yards is to store coal to meet production or consumption needs. Through reasonable planning and management, they ensure that coal maintains its quality and characteristics during storage, playing a buffer role in the coal supply chain, balancing supply and demand, and reducing the risk of supply disruptions caused by market fluctuations or transportation problems. Coal storage yards are an indispensable part of the coal supply chain, and their design and operation require comprehensive consideration of various factors to ensure efficiency, safety, and environmental protection.

[0003] In existing technologies, coal storage yards generate significant amounts of smoke and dust during coal unloading and stacking. This smoke and dust can pollute the surrounding air due to its dispersion, directly impacting environmental safety. It is generally suppressed by corresponding water spray pipes. However, existing water spray pipes require operators to manually align the spray, which can easily lead to missed spots. Therefore, we propose a dust suppression spraying device for open-air coal storage yards. Utility Model Content

[0009] Preferably, the water spraying device includes multiple water outlet pipes that penetrate the bottom of the water channel, multiple additional water outlet pipes that penetrate the side wall of the water channel, and atomizing nozzles that are fixedly connected to each of the multiple water outlet pipes. A through groove is provided through the side wall of the column at the corresponding position, and a water inlet pipe is connected to the through groove. A pipe groove is provided through the lower end of the top plate at the corresponding position, and a water delivery pipe is embedded in the pipe groove. One end of the water delivery pipe is located on the lower side of the top plate and is connected to the water inlet pipe, and the other end of the water delivery pipe extends through into the water channel.

[0010] Preferably, the sealing device includes a sealing plate disposed at the opening of the water channel, and a sealing plate fixedly connected to the inner wall of the water channel at the corresponding position. The position of the sealing plate corresponds vertically to the position of the sealing plate.

[0011] Preferably, each of the two columns has a threaded connection to an additional connecting screw on its side wall.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention utilizes a positioning device, a connecting device, a water spraying device, and a sealing device to create a device for dust suppression in coal piles. When dumping coking coal, the device can be placed at the unloading location or directly connected to the coal truck using connecting screws. Upon arrival at the unloading point, simply connecting a water pipe allows for spraying. This reduces dust and environmental pollution during unloading. Furthermore, the design of the column and roof plate is relatively simple, facilitating roof plate disassembly and subsequent cleaning of the multiple atomizing nozzles on the roof plate by operators.
