Embodiment 1

[0039] Design and manufacture a set of air pressure dismantling device for discarded mobile phones, the inner diameter of the tank body 1 is 150mm, and the wall thickness is 10mm. Tank 1 is 400mm high and has an effective volume of 0.007m 3 . 14 discarded mobile phones are loaded into the tank body 1, the tank body 1 is rotated to reach a vertical position, the electric control system 10 is started, and the lid 2 is closed. Start the air compressor 9 to raise the air pressure in the tank to 0.4~0.5MPa and keep it for 2 minutes. Operate the electronic control system 10 and open the cover 2 . After the gas is released, open the cabinet door of the box body 5, rotate the tank body 1, and pour the mobile phone into the material collection tray 6. The dismantling results showed that all 14 mobile phone shells were broken, and the dismantling rate reached 100% at one time. The batteries, LCD screens, circuit boards, shells and other parts can be collected directly by classificati...

Embodiment 2

[0041] Design and manufacture a set of air pressure dismantling device for discarded mobile phones, the inner diameter of the tank body 1 is 150mm, and the wall thickness is 10mm. Tank 1 is 400mm high and has an effective volume of 0.007m 3 . 20 discarded mobile phones are loaded into the tank body 1, the tank body 1 is rotated to reach the value position, the electric control system 10 is started, and the lid 2 is closed. Start the air compressor 9 to raise the air pressure in the tank to 0.3-0.4 MPa and keep it for 3 minutes. Operate the electronic control system 10 and open the cover 2 . After the gas is released, open the cabinet door of the box body 5, rotate the tank body 1, and pour the mobile phone into the material collection tray 6. The results of dismantling showed that among the 20 mobile phones, 17 shells were broken, and the dismantling rate reached 85%. Most of the batteries, LCD panels, circuit boards, shells and other parts can be collected directly by clas...

Abstract

The invention discloses an air pressure dismantling device and method for a waste mobile phone. The device comprises an air pressure tank, an air compressor and an electronic control system, wherein the air pressure tank comprises a tank body and a cover, a magnetically controlled switch is arranged between the tank body and the cover, a spring slideway is arranged above the cover, and opening and closing of the cover is controlled by the electronic control system; when the cover is closed, airtight connection is formed between the tank body and the whole cover; the air compressor is connected with the air pressure tank through a pipeline. According to the method, differential pressure inside and outside a mobile phone shell is produced, the mobile phone shell is broken from inside under the action of air pressure, and the purpose of mobile phone dismantling is achieved. The method and the device are green and environment-friendly, production of toxic and harmful substances in an implementation process is avoided, batch, efficient and environment-friendly dismantling of the waste mobile phones is realized, the waste mobile phone dismantling efficiency of an electronic waste dismantling enterprise can be greatly improved, and the labor cost is reduced.

Description

technical field [0001] The invention relates to the technical field of recycling electronic waste, in particular to a pneumatic dismantling device and method for discarded mobile phones. Background technique [0002] With the advancement of science and technology, electronic equipment is gradually developing towards integration, precision and miniaturization. Mobile phones have become an indispensable electronic device in people's daily life. According to statistics, in 2014, my country's smart phone users have exceeded 500 million, and the growth momentum is still strong. As a small electronic product that is updated quickly, a large number of mobile phones will be eliminated from the hands of users in the next few years and become electronic waste. On February 9, 2015, six ministries and commissions including the National Development and Reform Commission jointly issued the "Waste Electrical and Electronic Product Disposal Catalog (2014 Edition)", which included mobile p...
