working principle:

The stencil conveyor belt 2 is a hollowed-out steel mesh, on which the automobile instrument to be dedusted is placed. The automobile instrument travels from the right driven wheel 4 side to the driving wheel 3 side with the steel mesh conveyor belt 2. 9, the electrostatic precipitator 9 on the entrance side electrostatically removes dust from it, and blows downward to blow the dust particles attached to the automobile instrument to the water tank 6 on the entrance side, and the downwind part blown on the automobile instrument is blown to the water tank on the entrance side In 6, the other part turns after encountering the automobile instrument, and the wind after turning is sucked away by the first axial flow fan 10 and the second axial flow fan 11.

As the automobile instrument to be dedusted continues to advance, through the lower electrostatic precipitator 7, the lower electrostatic precipitator 7 electrostatically removes it, and blows upwards to blow the dust particles attached to the automobile instrument to the first axial flow fan 10 and the second The air inlet of the axial fan 11 sucks away.

As the automobile meter to be dedusted continues to move, it passes through the outlet-side electrostatic precipitator 8, and the outlet-side electrostatic precipitator 8 performs electrostatic dust removal on the automobile meter again, and blows downward to blow the dust particles attached to the car meter to the outlet side In the water tank 5, a part of the downwind blowing on the automobile instrument is blown to the outlet side water tank 5, and the other part turns after meeting the automobile instrument, and the wind after the steering is sucked away by the first axial flow fan 10 and the second axial flow fan 11.

On the travel route of the automobile instrument to be dusted, electrostatic precipitators are installed above and below, and the upper and lower surfaces are repeatedly dedusted. Part of the dust is stored in the water tank, and the other part is sucked away by the fan. Do your best to remove the dust on the automobile instrument The dust is removed cleanly. After the dust is removed, the automobile instrument slides into the material basket 14 through the material slide plate, and there is no need to manually pick it up. The whole process is automated, which greatly reduces the manual operation process. it is good.
