The utility model relates to the technical field of
air purification, and discloses an air conditioner return air inlet
air purification device adapting to the ship vibration environment, which comprises a return
air purification device main body, a filter cavity is formed in the return air purification device main body, and an air inlet is formed in the center of the top of the return air purification device main body. Ash
discharge holes are formed in the side surface of the return air purification device main body. By arranging the conversion
assembly and the sealing plate, when dust and sundries on the filter screen are cleaned, the sealing plate is rotated to seal the air inlet hole, the fan
impeller rotates reversely, the filter screen vibrates,
airflow is reversed, shaken-off dust is discharged through the dust discharging hole, the cleaning mode depends on cooperation of the internal structure of the device, parts do not need to be replaced frequently, the ship operation material cost is reduced, and the ship operation efficiency is improved. The
automation degree is high, manual participation is little, the labor cost is reduced, the labor saving effect is remarkable under the condition of large ships or multiple filter screens, vibration of the filter screens can be buffered and reduced by arranging the elastic blocks, dust is prevented from permeating into the interior, and the defect that dust is difficult to clean is overcome.
