Problems solved by technology

[0002] Today's era can be described as changing with each passing day, especially in the electronic product industry. Computer hardware motherboards, circuit boards, monitors, mobile phone motherboards, CPUs, etc. are all replaced at a very fast speed. At the same time, electronic waste is also increasing rapidly. Among them Waste circuit boards are a major issue. One way to deal with them is to landfill waste circuit boards. After the circuit boards are buried in the soil, toxic substances will be released to pollute the soil. The other way to deal with them is to burn them. Toxic smog pollutes the environment more seriously

Abstract

The invention discloses a waste circuit board recovery production process which comprises a crushing mechanism, a separating mechanism and a dust removal mechanism. The crushing mechanism comprises amulti-stage crushing device. The crushing mechanism is further connected with a cooling mechanism. The separating mechanism comprises a cyclone separator, a fifth conveyor and an airflow sorting machine, all of which are connected sequentially in series. The airflow sorting machine is provided with a metal outlet and a light material outlet. The light material outlet is connected with a circulating pipe, and the tail end of the circulating pipe is connected with the crushing mechanism. The interior of the crushing mechanism and the interior of the separating mechanism communicate with an air inlet of the dust removal mechanism. According to the waste circuit board recovery production process, after a waste circuit board is subjected to multi-stage crushing, recyclable metal can be recovered through the separating mechanism, gas generated in the recovery process is exhausted after dust removal, the aim of saving resources is achieved, and the environment can be prevented from being polluted.

Description

technical field [0001] The invention relates to the technical field of recycling waste circuit boards, in particular to a production process for recycling waste circuit boards. Background technique [0002] Today's era can be described as changing with each passing day, especially in the electronic product industry. Computer hardware motherboards, circuit boards, monitors, mobile phone motherboards, CPUs, etc. are all replaced at a very fast speed. At the same time, electronic waste is also increasing rapidly. Among them Waste circuit boards are a major issue. One way to deal with them is to landfill waste circuit boards. After the circuit boards are buried in the soil, toxic substances will be released to pollute the soil. The other way to deal with them is to burn them. Toxic smog pollutes the environment more seriously. Waste circuit boards also contain some recyclable metals and other materials. Throwing them away directly is not conducive to saving energy. How to recyc...
