[0030] The device for recycling and separating waste mixed plastics of the present invention includes a crushing device and a melting, sorting and recycling device. As a first embodiment of the present invention, please refer to figure 1 , the crushing device includes a crushing box 10, and the crushing box 10 is provided with a feeding mechanism that allows waste and old mixed plastics to enter the crushing box 10, a crushing mechanism that crushes waste and old mixed plastics into granular materials, and crushes the crushed granular materials. The material is discharged to the discharge mechanism of the melting separation recovery device. The feeding mechanism includes a rotary box door 11 placed on the side wall of the crushing box 10 to facilitate the entry of waste and old mixed plastics into the crushing box 10 .

[0031] The crushing mechanism includes a rotating platform 30 placed at the bottom of the crushing box 10 and controlled to rotate by a rotating mechanism, a...

Abstract

The invention discloses a waste mixed plastic recovery and separation device and method, and belongs to the field of waste mixed plastic resourceful reutilization. The device comprises a crushing device and a melting, sorting and recovery device; a feeding mechanism, a crushing mechanism and a discharge mechanism are arranged in a crushing box body of the crushing device; and a heating mechanism for heating granular materials to a molten state after crushing in a phase manner, a screening mechanism for separating the molten materials from non-molten granular materials and a plastic molding mechanism positioned at the bottom of a melting box body and recycling the molten materials after separation are arranged in the melting box body of the melting, sorting and recovery device. The recoveryand separation device can effectively classify waste mixed plastic generated in daily life and industrial production, separates different plastic to prepare relatively pure single plastic to realizeresourceful utilization, saves later machining process, saves the energy, and is simple in operation, high in the automation degree, high in sorting degree and wide in sorting range.

Description

technical field [0001] The invention belongs to the field of resource recycling of waste and old mixed plastics, and in particular relates to a recycling and separation device and method for waste and old mixed plastics. Background technique [0002] Plastic products have changed our production and lifestyle, and the problem that arises is that a large number of waste plastics pollute the environment and cause a huge waste of resources. These wastes generally become a part of domestic waste and industrial waste, such as granular mixtures produced by industrial grinding, waste mixed with various plastics, waste electrical appliances and electronic mixtures, and these mixtures are scattered due to improper handling. Second, it has caused serious harm to the environment. According to statistics, my country's annual production of waste plastics is about 1 million tons, accounting for about 70% of plastic production. The amount of waste plastics produced is so large, but the cu...
