Abstract

The invention discloses a device for processing a circuit board and recycling iron powder, and the device is applied to the field of motor vehicle hazardous waste treatment. The device comprises a housing which is provided with an opening in upper portion and is in the shape of an inverted cone, and a box body which communicates with the lower portion of the housing, wherein at least two crushingrollers with triangular teeth are sequentially arranged in the housing from top to bottom in the horizontal direction and the perpendicular direction; a pair of grinding hammers is arranged below thecrushing rollers in the perpendicular direction; a communication joint of the housing and the box body is equipped with a filter screen layer for allowing the grinding hammers to grind and operate; and a first belt conveying mechanism, a magnetic-separating roller, a second belt conveying mechanism, a scraper plate and a dryer are arranged below the filter screen layer. At present, recycling for the circuit board of the motor vehicle adopts burning and land-filling or adopts a chemical agent to soak and extract metal elements therein, so that secondary pollution on air and water is generated,the circuit board is not crushed, a space proportion of the waste circuit board is great, and the like. Through a reasonable structural design, the problems can be effectively solved.

Description

technical field [0001] The invention belongs to the field of motor vehicle hazardous waste treatment, and in particular relates to a circuit board treatment and iron powder recovery device. Background technique [0002] In the past ten years, with the rapid development of my country's economy, the number of national motor vehicles has shown explosive growth. According to statistics from the Traffic Management Bureau of the Ministry of Public Security, as of the end of March 2017, the number of motor vehicles nationwide exceeded 300 million for the first time, including 200 million cars. Such a huge base of motor vehicles will generate a lot of hazardous waste, whether it is maintenance or scrapping, among which the circuit board as the carrier of the motor vehicle control system is also one of the waste products. [0003] At present, for the recycling of motor vehicle circuit boards, incineration and landfill or chemical agent soaking are generally used to extract the metal...
