Temperature-controllable electronic waste crushing device and temperature control method thereof

Abstract

The invention discloses a temperature-controllable electronic waste crushing device which is composed of a crusher 1 and a temperature control device. The temperature control device comprises a temperature sensor 2, a condensing pipe group 3, condensing pipes 4, a condensate cooling and regenerating device 5, a reflux condensation pump set 6 and a temperature control system 7, wherein the condensing pipe group 3 is arranged in the cavity wall of the crusher, and the temperature sensor 2 is arranged on the inner wall of a cavity of the crusher; the reflux condensation pump set 6 and the condensate cooling and regenerating device 5 are arranged outside the cavity of the crusher, the reflux condensation pump set 6 is connected with the condensate cooling and regenerating device 5 and the condensing pipe group 3 through the condensing pipes, and the other end of the condensing pipe group 3 is connected back to the condensate cooling and regenerating device 5 through the condensing pipes 4, so that a closed-loop condensing system is formed; and the temperature control system 7 is connected with the temperature sensor 2 and the reflux condensation pump set 6. According to the temperature-controllable electronic waste crushing device, the heating problem in the electronic waste crushing process is solved, and toxic and harmful gas is effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of solid waste recycling, and in particular relates to a temperature-controllable electronic waste crushing device and a temperature control method thereof. Background technique [0002] In recent years, with the rapid development of the information industry, the replacement of electronic and electrical products has become faster and faster, and the life cycle of electronic products has become shorter and shorter. The average service life of a computer has changed from 10 years in the past to 4 years now. In 2009, mobile phones were eliminated after 2 years of use. In addition, the update speed of electrical appliances such as TVs, refrigerators, and air conditioners is also accelerating. While experiencing the convenience brought by high-tech, people also produce a large amount of modern waste - electronic waste. The output of electronic waste in my country is increasing at an alarming rate every year, an...

Problems solved by technology

However, during the crushing process, due to the high-speed impact between the rotor and the material, a large amount of heat will be generated, which will increase the temperature inside the crusher, and the plastics contained in electronic waste will melt due to the temperature rise, or even cracked at high temperature. Toxic and harmful gases such as polychlorinated biphenyls, polybrominated biphenyls, and dioxins are released, causing serious harm to the environment and human body. Therefore, controlling the temperature in the electronic waste shredder has become an urgent problem to be solved

[0004] The invention patent "A Garbage Crusher" (Zhang Jianping, Hang Bing, Zhang Tianming, CN101549315) proposes a garbage crusher. Through the improved knife rack and staggered through slots in the box, the cutter head of the crusher is not easy to Wear and tear, prolonging the service life, but does not involve the solution to the problem of heat generation during the material crushing process

The utility model "A Low-Temperature Roller Crusher" (Wu Xuanman, CN204638265U) proposes a low-temperature crusher, which utilizes the ventilation on the four walls of the crushing chamber to improve the heating problem when the machine is working, but this roll crusher is not applicable It is limited to electronic waste, and the ventilation and cooling method cannot meet the safe temperature required when electronic waste is shredded
