Release Time：2022-12-21 Source：Lithium battery recycling equipment Share：
Waste circuit board recycling equipment environmental protection processing technology, using purely physical methods to crush waste circuit boards into metal, non-metal in a separate state of mixed powder, and then use the air separation technology to separate and recover the metal and non-metal powder. The project technology has a metal recovery rate of more than 95% and a metal purity of more than 95%, which effectively reuses waste resources and does not pollute the environment. Application area: Environmental protection and energy saving.
Technology principle: sorting - conveying - crushing - grading - lifting vibration system - sorting - recycling - dust removal, in a fully enclosed recycling state, no Metal-containing solid waste has crushing equipment for coarse crushing, shear crusher for primary crushing, speed-adjustable hammer crusher for secondary crushing; the crushed mixture falls into the cyclone classifier after lifting into the vibrating screen, the graded non-metallic dust enters the bag dust collector; the powder of materials larger than 60 mesh enters the vibrating screen and is sorted out through the vibrating screen; 60 mesh, 40 mesh, 20 mesh and 10 The materials within 10 mesh are sent to the adjustable speed hammer crusher for secondary crushing; the materials less than 20 mesh are sent to the high pressure electrostatic sorter, which separates the metal and non-metal powder by rotating multiple dust collecting plates fixed in series by the central shaft; the separated metal powder is separated by the electrolytic production line to realize the high purity separation of various metals.
1、AC motor with frequency converter to achieve stepless variable speed control in different feeds
2、PIC automatically control the process of conveying and separating;
3、Conveying, feeding, crushing, separating, dust removal, recycling and other connected control systems;
4、With recycling cycle system;
5、Special mesh belt transmission structure, can completely correct the deviation;
6、When it fails, it can automatically shut down the working process.
7、Role significance (direct economic benefits and social significance)
Circuit board recycling equipment after the separation of plastics, non-metals, metals have a corresponding market value, through the recycling of renewable resources, will be a large number of social production and consumption of discarded resources reuse, not only to reduce the exploitation of primary resources, but also to save a lot of energy, and more help to achieve the sustainable use of resources. E-waste is a high degree of resource, with high positive benefits, the recycling of electronic waste as a secondary resource, whether from the perspective of waste disposal, reduce environmental pollution, or from the recovery of valuable metals, to alleviate the contradiction between supply and demand of resources, are very realistic significance, circuit board recycling equipment to promote the standardization and standardization of waste electrical appliances / solid waste electronic appliances disassembly and recycling technology. The economic benefits are considerable and will not cause any damage to the environment, which can really achieve both economic and environmental benefits.
