[0002] Coal preparation, also known as coal washing, is the process of separating clean coal that meets the quality requirements of users from raw coal. Coking coal has certain requirements for ash content and sulfur content, and washed clean coal must be used. During the coal preparation process, the coal washer consists of multiple conveyor belts and screening structures, which greatly increases the energy consumption of the coal washer.

[0003] The existing patent publication number is CN221288609U, which discloses a coal preparation dust removal device, including an outer box of the device, a coal preparation structure and a hopper structure. A coal preparation structure is arranged at the upper end inside the outer box of the device, and a collection box is fixedly connected to the middle part of the lower end inside the outer box of the device. The coal preparation dust removal device of the utility model, through the hopper structure and the pressing block and control switch at the lower end, etc., when collecting coal mine dust generated during coal preparation by the coal preparation mechanism at the upper end of the outer box of the device, the dust reduction nozzle arranged at the upper end inside the outer box of the device sprays atomized clear water to wet the dust, and the dust falls into the inside of the ash collection tank. When the weight of the dust in the ash collection tank reaches a certain value, the hopper body presses down the control switch through the pressing block, and the control switch directly electrically controls the electric push rod to extend, driving the pushing plate to push the dust, etc. When pushing, the dust pushes open the spring box door, and the dust can be cleaned through the dust outlet opened on the lower surface of the outer box of the device.

At the same time, the existing coal mine screening equipment consumes a large amount of electricity. For this reason, we propose a power supply energy-saving structure for coal preparation to solve the above-mentioned problems. Summary of the Utility Model
