Waste plastic recycling system

Abstract

The invention discloses a waste plastic recycling system. The waste plastic recycling system comprises a feeding unit, a rough washing unit, a fine washing unit, a dehydrating unit, a crushing unit, and a drying unit, wherein the dehydrating unit comprises a dehydrating barrel, a dehydrating shaft and a plurality of dehydrating wheels; the dehydrating shaft is rotationally arranged on the dehydrating barrel, and the dehydrating wheels are fixedly arranged on the dehydrating shaft; the crushing unit comprises a crushing barrel, a crushing rotating shaft, a plurality of stationary knives and a plurality of rotating knives; the drying unit comprises a flow control device and a drying device, wherein the drying device comprises a drying oven and a fan. The waste plastic recycling system is high in automation degree, low in manufacture cost and simple in structure and can be maintained conveniently, the production takts of all units are consistent, energy is saved, the production yield in unit time is high, the human invention is reduced and the labor investment is saved.

Description

technical field [0001] The invention relates to the field of waste plastic recycling equipment, in particular to a waste plastic recycling system. Background technique [0002] At present, with the development of society, people's domestic waste is increasing, and people's awareness of environmental protection is enhanced. It is not a long-term solution to take landfill measures. At the same time, due to the shortage of resources, people have to recycle domestic waste for long-term development; Plastic is one of the more common garbage in people's daily life. Waste plastics are extremely difficult to degrade in the natural state. Therefore, recycling and recycling waste plastics is an essential treatment method. Plastics are first classified, crushed, cleaned, and dried when recycling. Dried and re-pelletized to make it a renewable resource. [0003] Chinese patent CN201320321100.5 discloses a plastic recycling production line, which mainly includes a feeding device, a scre...

Problems solved by technology

[0004] Chinese patent CN201310047234.7 discloses a recycling system for waste plastics, which aims to solve the problem that the existing recycling system for waste plastics has a complex structure and cumbersome process. The rate is low, and the harmful gas produced in the recycling process of waste plastics will pollute the environment.

[0005] Although the above two patents can deal with waste plastics relatively well, due to their complex structure and high manufacturing costs, the initial investment costs are huge, and the recycling of plastics will be hindered by too much capital investment, which is inconvenient for large-scale promotion.
