Description

Technical Field

[0001] This utility model relates to the field of coal processing technology, specifically to a water spraying dust removal device for coal. Background Technology

[0002] The core of coal washing is to achieve efficient separation of coal and impurities (such as gangue and sulfur) by using physical, chemical or biological methods, taking advantage of differences in properties such as density, particle size and surface wettability.

[0003] Coal washing and processing requires the use of conveyor belts to transport coal to the washing and processing equipment. A large amount of dust is generated during transportation, so dust suppression is necessary. The current method is to spray water mist to increase the weight of coal dust particles, causing them to settle to the ground and reducing suspended dust in the air. However, traditional water spraying dust suppression equipment can easily spill water between the belt and the drive wheel, causing water accumulation on the belt and leading to safety hazards such as belt misalignment, coal spillage, and slippage.

[0011] Preferably, a reinforcing plate is fixedly connected to the protective plate.

[0012] Preferably, the water pipe is equipped with several sets of nozzles that spray downwards.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This utility model utilizes protective plates on both sides of the upper edge of the conveyor belt to prevent coal slag from falling between the conveyor belt and the fixed frame and affecting the transmission. Several downward-facing nozzles are installed at the bottom of the water pipe to spray water to treat the dust on the coal above the conveyor belt. At the same time, the baffle on the support plate and the protective plate form a protective space to prevent the dust-suppressing water from splashing to the outside of the conveyor belt and to prevent the dust-suppressing water from spraying onto the lower part of the conveyor belt and causing accidents such as water accumulation, deviation, and slippage.
