The utility model discloses a following technical scheme realizes above-mentioned purpose:
the utility model provides an air-tight seal structure of bearing for powder coating processing, includes cylinder body, material, blade, micropore board, suction nozzle, bearing, belt pulley, main shaft, the inboard of cylinder body is provided with the material, install the bottom of cylinder body the main shaft, the outside of main shaft is provided with the bearing, the top of bearing is in the bottom axial of cylinder body is provided with the suction nozzle, the top of suction nozzle is in the main shaft with install between the cylinder body the micropore board, the top of micropore board and connect in the main shaft is installed the blade, install the lower extreme of main shaft the belt pulley.
Preferably: the air inlet nozzle is connected with the cylinder body in a sealing mode.
Preferably: the blades are connected with the main shaft through keys.
Preferably: the belt pulley is connected with the main shaft through a key.
Compared with the prior art, the beneficial effects of the utility model are as follows:
a cavity is formed between the bearing and the cylinder body by a microporous plate (gas can pass through, powder cannot pass through), nitrogen is added into the cavity through an air inlet nozzle, and the nitrogen upwards passes through the microporous plate to form an air pressure area, so that the powder cannot enter the area, and the bearing is effectively protected.
