Problems solved by technology

The ambiguity of the subject of responsibility leads to the obvious disorder in the recycling process of mobile phones
At present, most of the recycled mobile phones are sorted, refurbished, flowed into the second-hand market, and resold to consumers; mobile phones that cannot be used directly are simply disassembled, and some usable parts are reused, while others are discarded as garbage ; those that are completely unusable are directly treated as garbage incineration, which not only causes waste, but also seriously pollutes the environment

Embodiment Construction

[0021] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0022] A method for recycling waste mobile phones. The specific steps of the recycling method for waste mobile phones are as follows:

[0023] S1: Collection of used and used mobile phones, place the used and used mobile phones collected and purchased on the market in one place and label them;

[0024] S2: Wash, wash the waste mobile phones collected in S1 with water, and dry them in a dryer, and control the drying temperature at 50-60℃;

[0025] S3: Disassemble, use tools to disassemble the used mobile phones, collect the plastic shells in place A, the used lithium batteries in place B, the circuit boards in place ...

Abstract

The invention discloses a waste mobile phone recycling method. The waste mobile phone recycling method comprises the following specific steps: S1, collecting waste mobile phones; S2, cleaning; S3, disassembling; S4, recycling plastics; S5, recycling sheet copper in spent lithium-ion batteries; S6, performing secondary crushing treatment; S7, separating; S8, crushing circuit boards; S9, recycling nonferrous metals of circuit boards; S10, separating and recycling mobile phone screen polarizer films. According to the strictly controlled waste mobile phone recycling method, recycling of waste mobile phones is realized, the plastics is effectively recycled, and meanwhile nonferrous metals in lithium-ion batteries and circuit boards are effectively separated out to be recycled, the pollution of waste mobile phone materials to the environment is avoided; besides, the waste mobile phone recycling method has the advantages of reasonable design, high safety and practicability, and therefore the method can be popularized and used widely.

Description

Technical field [0001] The invention relates to the technical field of waste mobile phone recycling, in particular to a method for recycling waste mobile phones. Background technique [0002] Used mobile phones are mainly composed of plastic casing, lithium battery, circuit board, display and other parts. These components contain lead, chromium, mercury and other toxic and harmful substances. If they are improperly handled or discarded at will, they will seriously pollute the soil and groundwater, posing a huge threat to human health. Waste circuit boards also contain brominated flame retardants such as polybrominated biphenyls and polybrominated diphenyl ethers, which are carcinogenic, teratogenic, and mutagenic. Plastics can also produce harmful gases during the combustion process. Waste mobile phones contain a small amount of valuable metals, especially precious metals, which have reutilization value. A study shows that theoretically, 0.45 kg of gold, 130 kg of copper and 2...
