[0034] The working principle of the dust suppression spray device for belt conveyor head unloading provided by the utility model is as follows: when the belt conveyor head starts to unload materials, the dust generated by the movement of the materials begins to diffuse. At this time, the dust suppression spray device starts to work, and the water level in the water tank 1 is monitored in real time through the water level float 4. When the water level is lower than the set value, the automatic water replenishment pump 2 automatically replenishes the water tank 1 from the external water source by opening the water inlet pipe valve 3 to ensure that there is sufficient water in the water tank. At the same time, the water outlet pump 6 transports the water in the water tank 1 to the upper annular water tank 9 through the water outlet pipe 5. In the upper annular water tank 9, the water is evenly distributed to each atomizing nozzle 13 through the pipeline. At the same time, the lower annular air box 10 receives compressed air from the air tank 15 through the air pipe 12. The air tank 15 continuously replenishes compressed air through the air compressor to ensure stable air pressure. The adjustable water valve 7 is used to control the output The amount of water delivered to the upper annular water tank 9 can be adjusted by adjusting the opening of the adjustable water valve 7 according to the amount of material discharged from the conveyor belt head and the dust concentration, thereby changing the amount of water mist sprayed from the atomizing nozzle 13. The adjustable air pressure valve 14 is used to control the air pressure in the lower annular air box 10. By adjusting the adjustable air pressure valve 14, the atomization effect of the water mist sprayed from the atomizing nozzle 13 can be changed, so that it can better combine with the dust in the air to achieve the purpose of dust suppression. The atomizing nozzle 13 is connected to the upper annular water tank 9 and the lower annular air box 10 through the quick connector 11. At the atomizing nozzle 13, water and compressed air are mixed to form water mist, which is sprayed through the atomizing nozzle 13 to cover the conveyor belt head discharge area. Due to the wetting effect of the water mist, the dust particles in the air are adsorbed in the water mist to form larger particles and settle, thereby effectively reducing the dust concentration in the air.
