Embodiment Construction

[0038] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0039] see figure 1 , which is a system block diagram of the toner cartridge recycling system in the present invention. It can be seen from the figure that the recovery system includes a toner drum crusher 100 , a negative pressure toner collection device 200 , a magnetic separator 300 , a high-pressure cleaner 400 , an eddy current separator 500 and a vibration separator 600 .

[0040] The toner cartridge crusher 100 is used for crushing the waste toner cartridges to be recycled, and has a closed structure as a whole, so as to prevent the toner powder produced when the toner cartridges are broken from affecting people and the environment.

[0041] The top of the toner cartridge crusher 100 is provided with a feed inlet, which is sequentially c...

Abstract

The invention discloses a recovery system and a recovery method for a selenium drum. The recovery system comprises a selenium drum crusher, a negative-pressure ink powder collecting device, a magnetic separator, a high-pressure cleaner, an eddy separator and a vibrating separator, wherein an input end of the selenium drum crusher is connected with a conveying device, and an output end of the selenium drum is communicated with the magnetic separator; the negative-pressure ink powder collecting device is arranged on the selenium drum crusher, so that the whole recovery system can work in a negative-pressure state; an output end of the magnetic separator is communicated with the high-pressure cleaner; an output end of the high-pressure cleaner is communicated with the eddy separator; a discharge end of the eddy separator is communicated with the vibrating separator. When the selenium drum is recovered, the selenium drum is crushed at first, the whole shell of the selenium drum is crushed in a length direction of the selenium drum for ensuring that a metal bar in the selenium drum falls off integrally, the fallen metal bar is integrally recovered, and other component materials of the selenium drum are recovered. According to the scheme, the metal bar in the selenium drum can be completely recovered and the reliability and the feasibility of the whole recovery system for the selenium drum are greatly improved.

Description

technical field [0001] The invention relates to a recycling technology of 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), magnets (NdFeB), plastics (ABS) and other materials with recycling value. In addition, waste toner cartridges also contain pollutants: carbon powder (toner). Carbon powder is a powder with extremely small particle size, and its main components are polyacrylate-styrene, ferric oxide, polyethylene / polypropylene paraffin, hydroxyaromatic acid derivatives,...
