Embodiment 1

[0025] Embodiment 1, a kind of waste toner recovery method, comprises the following steps:

[0026] (1) First, in a vacuum suction environment, disassemble the waste toner cartridge and waste toner cartridge, pour out the waste toner, and the waste toner will be sucked into a closed environment by vacuum suction, and will not be emitted into the surrounding atmosphere middle. Waste toner flows in a closed container, and the flowing toner is filtered to remove impurities such as screws with large particle sizes, plastic fragments, and other debris, and become purified waste toner;

[0027] (2) In a closed environment, use a fan or pump to form an air flow, and the waste toner that removes impurities and purifies flows in the air flow, and the powder filter mechanism that can only pass through the air but not the toner will flow with the air flow The waste toner is filtered out, and the filtered toner is collected and stored.

Embodiment 2

[0028] Embodiment 2, as figure 1 As shown, the waste toner recovery device includes an air cylinder 8, which is connected with an air extraction mechanism for twitching the flow of carbon powder, the front portion of the air cylinder 8 is provided with a filtering mechanism for filtering impurities, and the rear portion of the air cylinder 8 is provided with a filter for Exhaust filter mechanism and toner storage mechanism that can only discharge air impermeable toner.

[0029] The filter mechanism includes a filter cartridge 3. Since the waste toner cartridge and the toner cartridge are all waste, they may be mixed with many impurities, such as: screws, plastic fragments, other sundries and debris, waste carbon in the toner cartridge and the toner cartridge The powder may also be wet and agglomerated, so it is necessary to filter the raw material. A filter screen 1 is provided at the end of the filter cartridge 3 or at the front of the filter cartridge 3. In order to filter o...

Embodiment 3

[0035] Embodiment 3, a kind of regenerated plastic, is to use the waste carbon powder recovered by the method of embodiment 1 or the waste carbon powder recovered by the device of embodiment 2 as raw material, and is made by cooperating with waste plastic, wherein the weight percentage of waste plastic is 70-90%, and the weight percentage of waste carbon powder is 10-30%. Concrete can adopt following proportioning (percentage by weight):

[0036]

[0037] In the above table, the surface resistance is tested with a hammer-type surface resistance tester, and the gloss is obtained by using a specular gloss meter to test the light reflectance of the material at a certain angle, and then compare it with the light reflectance of the standard plate . Blackness is determined by visual inspection.

[0038] It can be seen from the table that after adding waste toner, the performance of the recycled plastic has been greatly improved, and the gloss has been greatly improved compared ...

Abstract

The invention discloses a recovery method and a recovery device for waste carbon powder, and regenerated plastic thereof. The recovery method for waste carbon powder comprises the steps of: conducting suction filtration to a raw material of waste carbon powder so as to remove impurities therein; pumping and filtering out the waste carbon powder with impurities removed, and collecting the powder for storage. The recovery device consists of an air duct, an air pumping mechanism connected to the air duct for pumping the carbon powder flow, a filtering mechanism arranged in front of the air duct for impurity filtration, an exhausting and powder filtering mechanism only able to exhaust air but unable to permeate carbon powder and a carbon powder storing mechanism that are positioned at the back of the air duct. The regenerated plastic is prepared by cooperation of the raw material of waste carbon powder recovered by the recovery method or the recovery device and waste plastic. The recovery method for waste carbon powder in the invention is simple and reliable, and has no environmental pollution. The recovery device for waste carbon powder in the invention has the advantages of simple structure, utility and convenience, high carbon powder recovery efficiency and no environmental pollution. Prepared by waste carbon powder, the regenerated plastic can have improved antistatic property or conductivity, and the plastic product can have better surface gloss.

Description

technical field [0001] The invention belongs to the technical field of recycling of waste and old articles, and relates to a method and a recycling device for recycling waste carbon powder in printing and copying consumables, and uses the waste carbon powder to manufacture a recycled plastic. Background technique [0002] With the extensive use of printers and copiers, toner cartridges, toner cartridges, and packaging bottles for storing toner are also discarded in large quantities. However, there are expired or residual waste in consumables such as waste toner cartridges, toner bottles, and toner cartridges Toner, but the toner in these wastes is difficult to recycle and use in copiers and printers due to factors such as impurities or moisture. At present, the most common method is to wash away the residual toner in the consumables with water, and recycle the toner cartridge and toner cartridge for reuse. However, the carbon powder washed away by water enters the soil and ...
