Description

Technical Field

[0001] The utility model relates to the technical field of mine dust reduction equipment, in particular to a spray fan used in mine development. Background Art

[0002] When conducting mining projects, the collected ore is usually piled on the ground at the mining site to facilitate later sales and transportation. The ore is usually shoveled into the bed of the transport vehicle by a forklift. In this process, dust is often caused, making the mine full of dust, which not only affects the operation but also causes harm to the health of the workers. Therefore, spray fans are usually installed in the mine to spray water mist on the ore piles in the mine to reduce dust.

[0003] The existing mine spray fans use fog cannons to atomize and spray the dust generated during the mining process. When the device is idle, the two ends of the fog cannon barrel are open and the mine is a dusty environment. Therefore, the diffuse dust in the mine is easy to accumulate in the fog cannon barrel when the device is idle, which not only easily causes blockage of the nozzle, but also affects the performance of the fan and its subsequent dust reduction effect, resulting in poor dust prevention effect of the device. Therefore, a mine spray fan is urgently needed to solve the above problems. Utility Model Content
