Steel shot recovery device

Abstract

The invention discloses a steel shot recovery device. The recovery device comprises a sand collecting vehicle, a cyclone separator and a negative pressure device, wherein a closed cavity is formed inthe sand collecting vehicle, a material suction port and a material outlet are formed in the two ends of the cavity in a penetrating mode correspondingly, and the material suction port is formed in the position of a steel shot to be recovered; the material outlet communicates with the side wall of the cyclone separator; and the negative pressure device communicates with the top of the cyclone separator. After the negative pressure device is started, negative pressure can be formed in the cyclone separator communicating with the negative pressure device and a pipeline in the sand collecting vehicle, the negative pressure enables steel shots communicating with the material suction port to enter a sand collecting vehicle through the material suction port, large-mass steel shots fall into a cavity of the sand collecting vehicle due to gravity, and small-mass dust and fragments enter the cyclone separator through the material outlet along with the negative pressure. The cyclone separator enables heavy gravels to be discharged from the bottom through vortex centrifugal force, and light dust to be discharged to the negative pressure device from the top. Through negative pressure adsorption, the steel shots and sand ash are recycled and separated, and the problem of dust raising is solved.

Description

technical field [0001] The invention relates to the recovery of industrial dust and materials, and is especially suitable for the recovery of casting steel shot and sand ash. Background technique [0002] Castings will form a large number of steel shots during the shot blasting process, and some steel shots will be hidden due to the complexity of the inner cavity of the casting. In order to keep no steel shot left in the inner cavity of the casting, it is necessary to dump the casting at different angles, and then use compressed air to clean the inner cavity of the casting. Four weeks, recycling is difficult, and the shot blasting process will generate more dust. The current main recovery method is to clean and gather the ground with a broom or use compressed air to clean and blow the ground for recovery. In this way, the dust in the recovery process will pollute the environment, and it is not conducive to the health of the staff; when the steel shot is recycled There are ...
