Waste circuit board disassembling method and waste circuit board disassembling device

Abstract

The invention discloses a waste circuit board disassembling method and a waste circuit board disassembling device. The device comprises a box body, a feed port gate valve, a high-temperature pulse valve, a pressure pump, a heat exchanger, a pressure sensor, a second pipeline exhaust port, an air purifier, an air suction pump, an observation window, a temperature sensor, a box body exhaust port, a discharge port gate valve, a circuit board component collection box, a soldering tin liquid discharge valve, a soldering tin liquid collection box, a buffer strip, a separation sieve plate, a transmission mechanism, a base, a vibrating plate, a motor, a thermal insulation layer and an electric heating rod. An electric heating method is used for controlling the temperature, and required disassembling force and advancing power are provided for a circuit board in a mode of combining the vibrating plate, the high-temperature and high-pressure pulse gas and the separation sieve plate, so that soldering tin liquid and electronic components are ensured to efficiently fall off from the circuit board and be smoothly discharged. The waste circuit board disassembling device is compact in structure, high in circuit board dismounting efficiency, low in equipment energy consumption, low in maintenance cost, free of environmental pollution and suitable for industrial application.

Description

technical field [0001] The invention belongs to the technical field of industrial waste treatment and resource regeneration, and in particular relates to a method for dismantling a waste circuit board and a dismantling device thereof. Background technique [0002] As we all know, electronic products, as a microcosm of the rapid development of modern technology, have brought huge changes to consumers' lifestyles, and people also favor the use of newer and iterative electronic products. The recycling of electronic waste, especially circuit boards, which are an indispensable component of electronic products, is increasing day by day. Statistics show that the global electronic product waste is 20-50 million tons per year, and it is increasing at a rate of 3%-8% per year. As of the end of 2018, China had to process 150 million sets (pieces) of electrical waste each year, including 72.69 million sets of televisions, 29.53 million sets of microcomputers, 16.53 million sets of refr...

Problems solved by technology

This invention has compact structure, uniform heating of circuit boards, high utilization rate of workshop space, circuit boards are processed in a closed environment, waste gas is recycled after purification, has no pollution to the environment, and is suitable for large-scale industrial applications, but the overall vibration of the vibration box, Not only does it cause huge power consumption, but the vibration box is easily damaged during the long-term vibration process, resulting in increased follow-up maintenance costs. At the same time, the huge noise generated by the vibration of the equipment greatly damages hearing
