The utility model discloses an aluminum
alloy waste treatment device, which relates to the technical field of
waste recovery and comprises a support frame, a crushing mechanism and a separating mechanism, the crushing mechanism is fixedly arranged at the top of the support frame and used for breaking aluminum
alloy waste, and the separating mechanism is fixedly arranged at the bottom of the support frame and used for separating the aluminum
alloy waste. The separation mechanism is arranged in the crushing mechanism and located below the crushing mechanism, the separation mechanism comprises a separation box, a first material guide plate, a second material guide plate, a third material guide plate and an air screen
assembly, a feeding port is formed in the top of the separation box, an air inlet, a
slag discharging port and a discharging port are sequentially formed in the side portion of the separation box from top to bottom, the
slag discharging port is located on the opposite side of the air inlet, and the discharging port is located on the opposite side of the
slag discharging port. The air screen
assembly is matched with the material guide plate, and aluminum alloy and plastic fragments are separated through the difference of the physical characteristics of the aluminum alloy and the plastic fragments. Impurities such as plastic fragments in the aluminum alloy waste are effectively removed, and the situation that in the follow-up recasting process, plastic is decomposed at high temperature to generate harmful gas to pollute the environment is avoided.
