Embodiment 1
[0049] attached figure 1 For the schematic flow chart of the present invention, refer to the appended figure 1 , the operating process of the present invention is:
[0050] Step 1 is picking. First, strictly inspect the waste wires sent to the workshop, and pick out non-wire debris such as iron wires, nails, and plastic ropes that may have been mixed in during the construction of the folded wires. Strictly prevent the mixing of hard objects and damage the cutter of the waste wire high-speed granulator. Mixing with sundries will cause the recycled metals and plastics to be impure.
[0051] Step 2 is dicing. The wire bundle is sent to the waste wire high-speed pelletizer for pelletizing. The length of the dicing should be 1 / 2-4 / 5 of the straight diameter of the wire. At this time, a single magnified dicing looks like a moon cake, with a metal core in the middle, and some of the diced metal cores have fallen off. , or almost falling out of itself.
[0052] Since the waste wi...

Abstract
The invention provides a processing method and special device for waste wires. The processing method and the special device are used for separating and recycling metal wires and plastic sheaths of the waste wires. The sorted waste wires are cut into particles through a special granulator, and metal cores and plastic sheaths are disengaged through grinding of a special umbrella-shaped plastic mill. Metal core particles and plastic sheath particles are separated through wind unceasingly blown out of a special winnowing machine. Plastic sheaths made from different materials can be separated through water separation. Finally, completely-separated metal cores and plastic sheaths are obtained. The processing method and the special device have the advantages that the number of devices is small, investment is small, the energy consumption is low, the operation cost is low, benefits are high, no loss is caused, metal wires and plastic sheaths are all recycled, the technology is simple and easy to grasp, the processing method and the special device are not related to complex devices and technologies for high temperature, ultra-low temperature, high pressure, combustion and the like, no pollution is caused, pyrogen is not generated, toxic substances not allowed to be discharged are not produced, and the processing method and the special device are high in practicability, capable of being used for various production scales and environments, easy to operate and suitable for being operated by people of all technical levels.
Description
technical field [0001] The invention is used to separate and recycle metal wires and plastic sheaths of waste electric wires. It belongs to the category of waste material reuse and environmental protection. Background technique [0002] With the development of the economy and the expansion of urban construction, the amount of waste wires has increased dramatically. It is common to see remote villages burning wires for recycling metals, and the downwind is shrouded in suffocating blue smoke, which seriously damages the environment. Although there are some processing methods for waste and old electric wires at present, each has its own advantages, but there are generally disadvantages such as large investment, high operating cost, low benefit, complicated technology, high energy consumption, and not suitable for small imitation. For example, in the "PE-type wire sheath pyrolysis method", the pyrolysis temperature needs to reach 600°C, and the pyrolysis product of the wire sh...
