With the continuous development of the electronic and electrical industry, various waste circuit boards are produced in large quantities, which is harmful to the environment. The circuit board recycling equipment can smash, separate and finally sort various 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 scheme of circuit board recycling equipment is: a dry separation waste circuit board production line, including a conveyor, a crusher, a primary crusher, a feeding auger conveyor, a secondary crusher, and a cyclone feeding that are connected in sequence. machine, air vibrating screen, elevator, electrostatic separator and conveyor, the discharge part of the conveyor is connected with the feeding part of the feeding conveyor; the air vibrating screen is provided with dust outlet, finished material outlet and semi-finished material outlet, The dust outlet is connected to the dust suction fan. After the dust suction fan, a pulse dust removal box is arranged in turn, and the semi-finished material outlet is connected to the hoist.
Waste circuit boards are pulverized into a mixture of metal and non-metal through conveyors, crushers, primary pulverizers, conveyors and secondary pulverizers in turn, and then enter the airflow vibrating screen through the cyclone feeder. The dust is sucked into the pulse dust removal box by the dust suction fan, part of the finished metal material is output through the finished material outlet of the airflow vibrating screen, and the other part of the mixture of metals and non-metals that is not completely crushed and separated is connected to the semi-finished material outlet of the airflow vibrating screen. The elevator is conveyed to the electrostatic separator for sorting, and the sorted metal finished materials are output through the finished material outlet of the electrostatic separator.
The circuit board recycling equipment is smashed and separated mechanically in sequence, and the economic efficiency is obvious, and various equipment for smashing, separating and sorting waste circuit boards are effectively combined to form a production line, the efficiency is greatly improved, and the environmental protection is greatly improved, while achieving the purpose of saving energy.
