Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of waste car recycling, in particular to a device for recycling waste metal materials after the crushing of a scrapped car. BACKGROUND

[0002] Waste cars, as an important material resource, have a high residual value and can be completely recycled according to market operation mode. After years of exploration, especially after the adoption of recycling technology and equipment, the components of each car can be recycled and reused. Among them, the non-ferrous metals need to be separated after the crushing of the components of the waste car.

[0003] For example, a patent with the publication number CN213287268U and the name "Non-ferrous metal separation device for waste cars" was granted on May 28, 2021. It includes a separation device, which includes a screening feed device and a vortex current sorter fixed to the right discharge end of the screening feed device. The front surface of the vortex current sorter is connected to the observation window. The screening feed device includes a sound-absorbing shell, a vibration screen inside the sound-absorbing shell, and a shock-absorbing assembly fixed to each other from top to bottom. The vortex current sorter includes a machine body and a conveyor belt fixed to the upper end of the machine body. The conveyor belt has a conveyor rotating wheel and a vortex current magnetic roller fixed to the left and right sides of the conveyor belt, respectively. Protective sheets are installed on the front and rear sides of the conveyor belt. The machine body has a non-ferrous metal outlet on the right surface and a non-metal outlet at the lower end. The right side of the conveyor belt is provided with a baffle. This non-ferrous metal separation device for waste cars has a shock-absorbing assembly at the lower end to reduce vibration. The shock-absorbing assembly absorbs the vibration through the internal spring. The existing technology has the following disadvantages. After the crushing and screening of the scrapped car, the magnetic metals and non-magnetic metals are mixed together, and different metals need to be recycled separately. The existing technology uses a permanent magnet roller to attract and separate magnetic metals. However, the permanent magnet roller does not clean the small magnetic debris when it attracts the magnetic metals. During the long-term screening of the magnetic metals, the permanent magnet roller has too much magnetic debris on its outer surface, which reduces the effect of the permanent magnet roller on attracting the magnetic metals and affects the recycling effect of the magnetic metals and non-magnetic metals.
