Efficient separation and recovery device of metal substances in building wastes

Abstract

The invention relates to the technical field of environmental protection machinery, and discloses an efficient separation and recovery device of metal substances in building wastes. The device comprises a frame; a feed port is fixedly mounted at the top end of the frame; a crushing device is rotationally connected between the left and right end wall bodies of the frame; and a screening plate is movably mounted under the crushing device between the left and right end wall bodies of the frame. An electric extension rod is fixedly mounted at the back end of a loading box; after the set gravity issensed through gravity induction, a trigger switch is started to control a lifting device to move up, and a rotating rod is driven to rotate to support a connecting rod to push a movable plate to move; after the lifting device reaches a set distance, an electric switch is triggered, an electromagnet is controlled to lose power and magnetism, and the metal substances on the electromagnet slide into the loading box under the gravity effect; and meanwhile, under the effect of the lifting device, the movable plate can be temporarily supported to store the building wastes from a crushing bin.

Description

technical field [0001] The invention relates to the technical field of environmental protection machinery, in particular to a high-efficiency separation and recovery device for metal substances in construction waste. Background technique [0002] With the continuous development of social economy, there are more and more types of mechanical equipment. As the old saying goes, science and technology is the primary productive force, and the development of science and technology cannot be separated from the development of the machinery industry. The two make progress and develop together. The transmission device, transmission device, working device, brake device and other parts can generally be divided into basic machinery, agricultural machinery, packaging machinery and environmental protection machinery. Environmental protection machinery includes water pollution prevention and control equipment and solid waste treatment equipment. [0003] With the acceleration of urbanization...
