Problems solved by technology
The waste plastics of the above-mentioned process cannot be tested and blended until they are granulated. Therefore, the properties of the modified waste plastic granules processed by the above-mentioned process are not uniform and the stability is poor.
[0005] 3. Due to the different properties of different batches of waste plastic raw materials, these materials are usually mixed randomly without formulating in the existing production methods. When the recycled waste plastics in the final production process are unqualified, it is difficult to trace the used The source of raw materials, the cause of product failure is difficult to troubleshoot
Waste plastic granules with non-uniform properties greatly increase the reject rate of downstream manufacturers, resulting in poor economic benefits and waste

The invention discloses a waste plastic recycling processing method. The waste plastic recycling processing method comprises the following steps that (1), original materials are classified based on sources of waste plastic; (2), original materials of one source is taken into a unit, the original materials are positioned in a smashing cleaning dewatering module to conduct smashing, cleaning and dewatering, and therefore clean waste plastic pieces are obtained, and the clean waste plastic pieces are stored in piece material storing containers, and the clean waste plastic pieces in each piece material storing container are sampled and detected; (3), according to performance requirements of target products, a material feeding scheme is made for material mixing, and the clean waste plastic pieces in the piece material storing containers are positioned in a piece material mixing device for uniform mixing based on the material feeding scheme; and (4), the mixed clean waste plastic pieces areconveyed to a modification pelleting device to conduct modification pelleting processing, and waste plastic particles are produced.
Description
technical field [0001] The invention relates to a method for producing waste plastics, in particular to a method for recycling and treating waste plastics. Background technique [0002] The recycling and reuse of waste plastics can not only save resources, improve the utilization rate of materials, but also protect the environment and reduce its footprint, so its development prospects are broad. Most of the existing waste plastics treatment includes crushing and cleaning, dehydration, modified granulation, packaging and other processes. In the existing waste plastic recycling application field, there are the following deficiencies: [0003] 1. The production of different process stages is completed by different manufacturers. For example, manufacturer A is only responsible for the crushing and cleaning of waste plastics, while manufacturer B is responsible for heating the waste plastics after crushing and cleaning to form granules. Mixed modification (may be reheated to ca...
