At present, a trestle flushing device of a coal preparation plant is equipment for cleaning coal, and plays an important role in the coal treatment process. Coal preparation plants transport coal of different granularities from storage areas to processing equipment through trestle, and trestle flushing devices are used for washing coal in the coal loading process, and trestle flushing devices usually consist of a water spray system and a flushing tank. During coal loading, the water spray system sprays water through the nozzles onto the coal to clean the coal of dust, impurities and fine particulate matter on the surface. The flushing tank is a region containing flushing water into which the flushed coal falls, and the flushing water is discharged through a drainage system. The trestle flushing device has the functions of removing impurities on the surface of coal and improving the quality and purity of the coal.

The method has good ground washing effect, no dust is left, and the rubber hose can be washed to any position on the ground of the trestle as long as the rubber hose is long enough, but the method has the disadvantages of taking up labor time, and the rubber hose is too long, heavy and inconvenient to drag. At present, the cleaning mode of an automatic flushing pipeline is also applied to the market, a pipeline is fixed below a conveying belt, a plurality of groups of fan-shaped spray heads are arranged in the length direction of the pipeline, one end of the fixed pipeline is connected with an electric valve, the input end of the electric valve is connected with a high-pressure water supply pipe, and the electric valve is controlled by an electric control cabinet and can set flushing time and flushing interval time.
