Problems solved by technology

Although this utility model improves the safety of toner recycling to a certain extent, it still fails to avoid the phenomenon that toner particles and dust particles are mixed together during the process of collecting toner by the vacuum cleaner. At the same time, the concentration of toner and dust particles in the vacuum cleaner is relatively high , there is a danger of explosion when the vacuum cleaner is exposed to high temperature outdoors

Abstract

The invention relates to a method and device for recovering waste and old selenium drums. The method comprises the steps of: firstly, crushing waste and old selenium drums into scraps of 5mm-15mm by adopting a roll crusher and a hammer crusher; secondly, separating carbon powder from the waste and old selenium drums by adopting a negative-pressure type cyclone separating system, and collecting dust in the waste and old selenium drums by using a bag-type dust collector; thirdly, separating magnetic metal particles from the crushed waste and old selenium drums by adopting a magnetic separator; and finally, separating copper, aluminum and plastic particles from the crushed waste and old selenium drums by adopting a vortex separation method. According to the method and device provided by the invention, the working efficiency of recovering the waste and old selenium drums is improved, effective separation of carbon powder from dust is realized, meanwhile, the concentration of particles in the bag-type dust collector is reduced, and the hazard of explosion due to over-high concentration of the carbon powder and the dust in a cyclone separator during the treatment process is avoided.

Description

technical field [0001] The invention relates to environmentally friendly recycling of waste toner cartridges, in particular to a recycling method and a recycling device for waste and old toner cartridges. Background technique [0002] Modern office has higher and higher requirements on the quality and quantity of office accessories. Printers, copiers, and fax machines are constantly updated, and the scrapping of photosensitive drum accessories has produced a large number of used toner cartridges. According to statistics, in 2009 Shanghai collected as many as 4 tons of waste toner cartridges. China produces about 80 tons of used toner cartridges every year. [0003] Waste toner cartridges contain aluminum (Al), copper (Cu), iron (Fe), magnet (NdFeB), plastic (ABS) and other materials with recycling value. The content is: aluminum 12.4%, copper 0.1%, iron 39.9% , magnet 4.6%, ABS plastic 34.8%. In addition, waste toner cartridges also contain pollutants: carbon powder (ton...
