Abstract
The present invention relates to a full pneumatic dry type dust collecting vehicle which completes operation by airflows fully without a brush or water spray so as to change working principles of the existing sweeping vehicles. The dust collecting vehicle is provided with a centrifugal impeller. When the centrifugal impeller rotates, airflows drive dust which is sucked into a lower layer of a dust box through an air suction pipe. First separation is realized by gravity sedimentation. Fine powder dust enters the impeller once more, and secondary separation of air and the dust is realized by the centrifugal force generated by high-speed rotation. The separated dust is stored in the dust box, while the separated air is blown out of a jet nozzle of a dust suction disk so as to blow dust on the ground upwards and then is sucked by the air suction pipe. Therefore, the dust collecting vehicle of the present invention can effectively clear dust and sundries on the ground without secondary dust blowing pollution. The present invention is a product with the advantages of energy saving, water saving, high efficiency, environmental protection and sanitation.
Description
