Description

Valuable metal recovery device for plated waste plastics

The present invention relates to a valuable metal recovery device for plated waste plastics, and more particularly, by peeling expensive valuable metals plated on waste plastics discharged from industrial sites or daily life products from the waste plastics to recover and reuse the waste plastics. It relates to a valuable metal recovery device for plated waste plastics that makes it possible to recover expensive valuable metals peeled off from the waste plastics.

As is well known, plated ABS (acrylonitrile, butadiene and styrene) plastics are widely used as exterior materials for automobiles, electrical and electronic products, and daily life products because of their high hardness and lustrous luster.

The plating layer of the plastic is plated in the order of copper-nickel-chromium from the inside. In manufacturing plated plastic exterior materials using the characteristics of metal chrome with high hardness and excellent gloss as a surface material, since the adhesion of chrome to plastic is poor, copper and nickel are first plated on plastic and then chrome is plated on the surface Manufactures ABS plastic exterior materials.

On the other hand, in recent years, as a large amount of scrap automobiles and waste electrical and electronic products in which plated ABS plastic was used as an exterior material is generated, inevitably, a large amount of waste plated ABS plastic is generated.

As such, waste-plated ABS plastics generated in large quantities contain valuable metals such as chromium, nickel, and copper as well as plastics, so it is a very valuable secondary resource for Korea, a resource-poor country.

However, metal recovery and detoxification are possible only through several processes for complex materials containing such valuable metals, but the recovery method using a large-scale plant melting furnace is currently impossible.

Therefore, it is necessary to recognize waste as a resource, maximize the circulating resources required for production and distribution from waste, and develop a recycling process and system for resource circulation to maximize energy recovery and develop environment-friendly technology. Do.

On the other hand, various metals and high-performance alloys are being used due to the rapid growth of the electronics industry, and since they contain a large amount of harmful substances, their treatment is a problem. Therefore, it is necessary to overcome the limitations of existing commercial plants that recover molten metal, and to develop eco-friendly recycling technology that combines mechanical pretreatment technology and wet recovery technology.

In a situation where exports are blocked due to China's recent decision to ban the import of waste, Korea, which relies on importing all industrial raw materials, urgently needs to develop a new technology that recovers valuable metals from waste and recycles them as industrial raw materials.

Accordingly, in Patent Application No. 10-2020-0022162, a device for separating and extracting valuable metals from waste PCBs has been proposed.

Looking at it, the conventional device for separating and extracting valuable metals from a conventional waste PCB has a support frame for mounting and supporting a heating drum, and an inlet through which the waste PCB is put at one end, except for the mounting parts separated and extracted from the waste PCB at the other end. A heating drum having an outlet for collecting the waste PCB and installed at an angle to the support frame so that the outlet is positioned upward from the inlet by a certain inclination angle, and one or more electric heating plates installed around the heating drum to heat the heating drum; A heating air compression pump mounted at one place of the drum and generating heated air to inject high-temperature heating air into the heating drum, and a waste PCB that is rotatably installed inside the heating drum and put in through the inlet. A transfer screw for separating and extracting components mounted on the waste PCB while gradually transferring it in the direction of the outlet, and a drive motor for rotatingly driving the transfer screw for transferring the waste PCB, wherein the transfer screw is a heating drum A screw drive shaft that is supported by rotation on the screw drive shaft, a transfer blade spirally installed with a predetermined rotation radius on the outer circumferential surface of the screw drive shaft, and a component mounted on a waste PCB installed at a height smaller than the rotation radius of the transfer blade in the pitch section of the transfer blade It includes a lift-up guide diaphragm for inducing drop-off, and the transfer blade is further provided with a delay retention groove for mounting parts at regular intervals to delay the feed rate of the waste PCB to induce drop-off of the mounted parts, and the heating air compression pump is made of synthetic rubber and has a helical compression chamber penetrating therein; a stator heater embedded in the cylindrical stator to electrically generate heat; and a helical protrusion on the outer circumferential surface to be rotatable in the helical compression chamber of the cylindrical stator It is configured to include an inserted rotator and a stator reinforcing housing coupled to the outer circumferential surface of the cylindrical stator.

However, in the conventional conventional separation and extraction and recovery of valuable metals of waste PCBs configured in this way, the heating drum and the transfer screw are made of metal because the heating drum maintains an internal temperature of 200° C. or higher in order to melt and separate the solder from the waste PCB. This has a disadvantage in that it is difficult to use because the device is corroded by the salt in a short time, especially when it is intended to separate and recover valuable metals from waste plastics having salt.
