Problems solved by technology

[0009] However, none of the above-mentioned technologies can completely separate the components of waste paper, plastic and their composite materials, making it more difficult for resources to be recycled with high value.
The plastic in the color board is low-density polyethylene, because of its low strength and easy aging, the use of corresponding products is also affected; plastic particles can only be used as additives to resist inferior products

Embodiment Construction

[0021] see figure 1 , the recycling system for waste paper, plastic and their composite materials of the present invention consists of a set of feeding and sorting equipment 1, crushing equipment 2, winnowing equipment 3, cleaning equipment 4, beating equipment 5, pulp water treatment equipment 6, sewage It is composed of processing equipment 7, waste plastic refueling equipment 8, aluminum powder recovery equipment 9, automatic control and safety protection equipment 10, etc.

[0022] The waste enters the loading and sorting equipment 1: it is loaded through the hopper, continuously transported by the conveyor belt, and sorted by the manual sorting table. The waste materials are sent to the material crushing equipment 2 by the screw conveyor through the hopper: the waste materials enter the high-efficiency coarse crusher for crushing from the hopper to improve the production efficiency of the follow-up; the crushed waste materials are sent to the winnowing equipment by the sc...

Abstract

The invention discloses a resource recycling system of discarded papers, plastics or composite materials thereof. The discarded papers, plastics or composite materials thereof are subjected to manual sorting to remove impurities; muddy sand is removed through crushing and cleaning; high-quality paper pulp is recycled by using a powerful water power pulping method; the pulped remained waste plastics are dried and subjected to low-temperature catalytic pyrolysis and cooling to manufacture precious fuel oil; and the cracked residual slag including active carbon powder, aluminum crumbs and the like is subjected to high-temperature baking to recycle nonferrous metal aluminum, so as to realize total resource recycling utilization of the discarded papers, plastics or composite materials thereof. Processes, such as sewage treatment, waste gas treatment and the like in the system, can ensure that harmful pollutants of waste materials are not discharged in the recycling treatment process so as not to bring hazard to the environment. The resource recycling utilization of the discarded papers, plastics or composite materials thereof is beneficial to the realizing of harmonious human and environment and sustainable development of human society.

Description

technical field [0001] The invention relates to a recycling system for waste paper, plastic and their composite materials. The system is an important part of the urban waste resource treatment system and belongs to the field of environmental protection and urban waste treatment. Background technique [0002] Waste paper, plastic and their composite materials refer to the waste of product packaging and promotional materials made of plastic, paper or materials containing a small amount of aluminum foil, such as packaging of fresh milk, yogurt, lactic acid drinks, carbonated drinks and fruit juices Bags / boxes (common Tetra Pak pillows, Tetra Pak bags, etc.), daily necessities (including: cosmetics, snacks, medicines, etc.) packaging bags / boxes, disposable water cups, plastic-sealed advertising color pages, and product labels [0003] Waste paper, plastic and their composite materials account for nearly 1 / 3 of the total mass of urban waste. This part of waste cannot be decompose...
