Low-value waste plastic vacuum feeding system

Abstract

The invention relates to a low-value waste plastic vacuum feeding system which is applied to the field of low-value waste plastic treatment and comprises a support arranged between a constant feeder and a continuous pyrolyzer, a storage device, a vacuumizing device and a conveying device are sequentially arranged on the support, a feeding port of the storage device is used for receiving materials output by the constant feeder, and a discharging port of the vacuumizing device is used for discharging the materials output by the continuous pyrolyzer. A discharging port of the material storage device is communicated with a feeding port of the vacuumizing device through a first discharging pipe, a discharging port of the vacuumizing device is communicated with a feeding port of the material conveying device through a second discharging pipe, a discharging port of the material conveying device is communicated with a feeding port of the continuous pyrolyzer, a first electromagnetic valve is arranged on the first discharging pipe, and a second electromagnetic valve is arranged on the second discharging pipe. And a second electromagnetic valve is arranged on the second discharging pipe. The continuous pyrolyzer has the technical effects that the possibility that the pyrolysis effect of the low-value waste plastics is poor due to the fact that external air enters the continuous pyrolyzer along with the feeding process of the materials is reduced, and therefore the pyrolysis effect of the continuous pyrolyzer on the low-value waste plastics is improved.

Description

technical field [0001] This application relates to the technical field of low-value waste plastics treatment, in particular to a vacuum feeding system for low-value waste plastics. Background technique [0002] In our daily life and various fields of agricultural production, plastic products are ubiquitous. When the life of these plastic products or the purpose of use is reached, they will be discarded and become waste plastics, that is, low-value waste plastics; low-value waste plastics After centralized collection, it can be recycled after multiple processes such as purification, separation, crushing and granulation, and turned into plastic particles of different colors and materials as raw materials for downstream factories. [0003] In the related art, in the process of centralized recycling of low-value plastics, it is necessary to use a quantitative feeder to transport the materials to be processed, and then use a continuous pyrolyzer to perform pyrolysis treatment on ...
