[0032] Working principle: All electrical components mentioned in this application are externally connected to a power supply and control switch during use. After installation, first check the installation, fixation, and safety precautions of this utility model before use. Before use, the user adjusts the height of the guide chute 4 to adjust the distance between the guide chute 4 and the belt conveyor 2. During adjustment, the motor 151 is started, which drives the rotating shaft 147 to rotate. The rotating shaft 147 drives all the bevel gears 146 on the same side to rotate. The bevel gears 146 mesh with the bevel gear 145 to rotate, which in turn drives the screw 144 to rotate. This causes the screw 144 to drive the slider 143 to slide within the groove 142, causing the slider 143 to lift the fixed shell 3 and the guide chute 4, thus ensuring that the sealing strip 16 and the material centering soft plate 17 are in contact with the conveyor belt on the belt conveyor 2. During use, the material falls onto the belt conveyor 2 through the coal drop pipe 9, and the impact generated by the falling material... The impact energy is converted into the power to circulate and settle dust, allowing the dust to circulate effectively in multiple paths within a confined space and deplete its energy, eventually falling back onto the conveyor belt. Based on aerodynamic principles, the flow characteristics of airflow are utilized to create circulation of dust-laden airflow within specific channels or devices, reducing airflow velocity and allowing the dust to settle naturally under gravity and inertia. During the material transport within the feed chute 4, the air-water distributor 10 is activated via the control box 11, atomizing water into micron-sized dry mist particles through the dry mist nozzles 13. These dry mist particles are extremely small, similar in size to dust particles, allowing them to better bind with the dust. When the dry mist particles diffuse in the air, they collide and agglomerate with the flying dust particles, increasing the weight of the dust particles, which then settle under gravity, achieving a dust suppression effect. During this process, the effect of non-powered dust removal is achieved through a secondary circulation pressure relief device 6, a non-powered dust damping device 7, and a primary circulation return air device 8.
