Description

Technical Field

[0001] The utility model relates to the field of coal mining, in particular to an energy-saving and environmental protection dust removal device for a coal receiving pit in a coal shed. Background Technique

[0002] Coal mining refers to the process of extracting coal resources from underground or open-pit deposits through various technical means. This is a complex and challenging industrial process involving multiple aspects such as geological exploration, mine design, mining engineering, and safety management. When coal mining, a coal storage shed is generally used to store coal to prevent the coal from being drenched in rain and polluting the environment during windy days. It is an energy-saving and environmental protection project; the main building function of the coal storage shed is a large storage warehouse. The coal receiving pit arranged inside the coal storage shed is mainly used to store coal and is transported by a conveyor belt. Therefore, there is a large amount of dust in the coal storage shed, so it is necessary to carry out dust reduction treatment on it.

[0003] The Chinese patent with the publication number CN211885977U discloses an energy-saving and environmental protection dust removal device for a coal receiving pit in a coal shed, including a coal shed and a coal receiving pit arranged inside it. There are access doors opened on the coal shed at the two sides of the coal receiving pit facing each other. Concentrically arranged inside the upper end of the coal shed are an outer coil pipe and an inner coil pipe facing the coal receiving pit. The outer coil pipe and the inner coil pipe are fixed to the top of the coal shed through fixing rods. The outer coil pipe and the inner coil pipe are respectively communicated and fixed with a conveying pipe through a first branch pipe and a second branch pipe. However, in the above patent, by installing the inner coil pipe and the outer coil pipe at the bottom of the coal shed for spraying water, after the dust is subjected to the spraying pressure from above, the dust will diffuse outside the coal receiving pit, which is not convenient for spraying to treat the dust. Therefore, those skilled in the art provide an energy-saving and environmental protection dust removal device for a coal receiving pit in a coal shed to solve the problems raised in the above background technique.
