Working process of circuit board recycling equipment

With the continuous development of the electronic and electrical industry, a large number of waste circuit boards are produced, which is harmful to the environment. In contrast to this, the processing industry of waste electronic products in my country has not yet formed a scale, and its recycling value has gradually attracted attention and has become a promising industry. This is an opportunity for the development of environmental protection machinery. However, the composition of the waste circuit boards is messy and the disposal is difficult. How to make the recycling process more environmentally friendly, economical and energy-saving is the main problem facing this field. Circuit board recycling equipment realizes environmental protection, economy and energy saving in the process of crushing and separating waste circuit boards. It provides a dry separation waste circuit board production line that effectively combines various equipment for crushing, separating and sorting waste circuit boards. , So that it can achieve a greater energy-saving effect in the production process, and achieve a higher metal separation rate.

The technical plan of circuit board recycling equipment is: a dry separation waste circuit board production line, including successively connected conveyors, crushers, primary crushers, feeding hinge conveyors, secondary crushers, and cyclone feeding The discharge part of the conveyor is connected with the feeding part of the feeding conveyor; the air vibration screen is equipped with a dust outlet, a finished material outlet and a semi-finished material outlet. The dust outlet is connected to the dust suction fan. After the dust suction fan, there is a pulse dust removal box in turn, and the semi-finished material outlet is connected to a hoist; the electrostatic sorter is equipped with a discharge outlet, a finished material outlet and a semi-finished material outlet.

Waste circuit boards are pulverized into a mixture of metal and non-metal through the conveyor, crusher, primary crusher, conveyor and secondary crusher in turn, and then enter the air-flow vibrating screen through the cyclone feeder, and the air-flow vibrating screen Dust is sucked into the pulse dust removal box by the dust suction fan. A part of the finished metal material is output through the finished material outlet of the air flow vibrating screen, and the other part of the metal and non-metal mixture that is not completely crushed and separated is connected to the semi-finished material outlet of the air flow vibrating screen. The hoist is conveyed to the electrostatic sorter for sorting, and the sorted metal products are output through the finished product outlet of the electrostatic sorter.

Circuit board recycling equipment is mechanically crushed and separated in sequence, which has obvious economic efficiency, and effectively combines various equipment for crushing, separating and sorting waste circuit boards to form a production line. The efficiency is greatly improved, and the environment is solved. At the same time of pollution, the purpose of saving energy consumption is achieved.
