Embodiment Construction

[0017] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with examples, which are only used to explain the present invention, and do not constitute a limitation to the protection scope of the present invention.

[0018] A method for recycling, processing and reusing waste plastics, comprising the following steps:

[0019] a: Transport the waste plastics collected from the source of waste plastics to the waste recycling device, and pre-treat the waste plastics such as sorting and dust removal;

[0020] b: The pretreated waste is melted in a furnace and extruded into strips by an extrusion device. The extrusion device also includes an automatic cleaning detection device, which is automatically analyzed by PLC and sends out a cleaning signal. The extrusion device uses a salt solution for cleaning. Cleaning, the salt solution is processed through the concentration adjustment box, the salt solution is...

Abstract

The invention discloses a waste plastic recovery, processing and reutilization method. The method includes the steps of: a: conveying waste plastics collected from waste plastic sources to a waste recovery device, and conducting picking, dust removal and other pretreatment on the waste plastics; b: subjecting the pretreated waste to melting treatment by a melting furnace, and extruding the treatedwaste into strips by an extrusion device; c: spin-drying the plastics extruded into strips by a centrifugal dehydration device, and conveying the dried plastics to a cutting forming device; d: cutting the strip plastics into granules by the cutting forming device, and collecting the granules together into a storage tank; and e: packaging the finished product in the storage tank. The method provided by the invention adopts a PLC control system for centralized monitoring, management and automatic program control, realizes intelligent cleaning of the production devices, guarantees the processingquality of the product, also realizes recycling of waste plastics, realizes resource recycling of waste produced by plastic plants, also saves the production cost for plastic plants, and improves economic benefits.

Description

technical field [0001] The invention relates to the technical field of plastic processing, in particular to a method for recycling, processing and reusing waste plastics. Background technique [0002] The amount of waste plastics is very large. If it can be recycled and reprocessed, it will have good environmental protection and energy-saving results. For plastic factories, the waste plastics released by industrial production can be fully realized as resources, which not only realizes the realization of waste plastics recycling. Resource utilization saves production costs for plastic factories. However, in actual operation, because the production process does not pay attention to cleaning and sanitation, or there is a phenomenon of incomplete sanitation, more impurities appear in plastic products, which directly affects the use of plastic products. [0003] Therefore, in order to solve the above-mentioned existing problems, the present invention provides a new technical sol...
