Multi-step type aluminum-plastic separation device

Abstract

The invention belongs to the technical field of separation, and particularly relates to a multi-step type aluminum-plastic separation device which comprises a pulverizer, a pyrolysis separation device and a hydrolysis tank. The pyrolysis separation device comprises a shell and a steam generation device, a stirring shaft with a hollow axis is arranged in the shell, and the top end of the stirring shaft penetrates through the top of the shell. The steam device is provided with a steam guide pipe, the steam guide pipe is rotationally connected with the top end of the stirring shaft, stirring rods are longitudinally arranged on the outer side face of the stirring shaft at intervals, vent holes are formed in the surfaces of the stirring shaft and the stirring rods, grading plates are arranged on the inner wall of the shell at intervals in the radial direction, and the grading plates and the stirring rods are arranged at intervals. The grading plates are provided with electric control valves used for controlling aluminum plastic materials to pass through. According to the multi-step type aluminum-plastic separation device, aluminum-plastic materials are separated layer by layer, the aluminum-plastic materials are heated, melted and shrunk step by step, and the excellent aluminum-plastic separation effect is rapidly achieved.

Description

technical field [0001] The invention belongs to the technical field of separation, and in particular relates to a multi-stage aluminum-plastic separation device. Background technique [0002] At present, there are many optical fibers and communication cables on the market. The sheath of the outer layer of the optical fiber or communication cable is made of a layer of plastic and aluminum (or iron) adhesion as a whole. After use of such materials, people pay attention to their recycling insufficient. In the early days, the use of incineration to dispose of waste materials would cause a large amount of toxic gases to be produced from waste outdoor interplanted plastics, which would endanger human health; landfill treatment would occupy land and cause long-term pollution of soil and groundwater. [0003] At present, when separating waste aluminum-plastic cables formed by compounding aluminum foil and plastic, wet separation technology is usually used, that is, the waste alumin...

Problems solved by technology

In the early stage, the use of incineration to dispose of waste materials will cause a large amount of toxic gases to be produced from the waste outdoor interplanted plastics, which will endanger human health; landfill treatment will cause land occupation and long-term pollution of soil, groundwater and other hazards

[0003] At present, when separating waste aluminum-plastic cables formed by compounding aluminum foil and plastic, wet separation technology is usually used, that is, the waste aluminum-plastic cables are soaked in a separating agent, and the adhesion between the layers is destroyed by dissolution or swelling. Combined force to separate the aluminum and plastic. In the prior art, when separating the waste aluminum-plastic cables, the intermittent batch separation method is generally adopted. The waste and old aluminum-plastic cables are in contact with the separating agent solution in an alternate manner. The feed time is long, and the required separation reaction time is long, which makes the processing capacity of the batch-type separation process low
