Problems solved by technology

[0002] At present, in the maintenance and replacement of power lines and equipment, a large number of waste power cables are produced. Among these waste power cables, especially high-voltage waste cables, they often need to be recycled before they can be used as raw materials for cable production. Cable production to achieve resource recycling. Currently, when recycling the conductors of waste cables, the waste conductors are often mixed and smelted with brand-new conductors in a certain proportion to prepare brand-new cable conductor materials. Although it can meet the needs of waste and old Requirements for the recycling of cable conductors, but the efficiency of the recycling operation is low, and due to the complex smelting and processing operations, difficult operation, poor product quality stability and reliability, it is easy to cause the electrical conductivity, mechanical structure performance, and resistance of the regenerated cable conductor material There are defects in corrosion performance to varying degrees, which leads to the relatively poor performance of cable products prepared from recycled conductors, which cannot effectively meet the needs of actual use. Therefore, in response to this problem, it is urgent to develop a new recycling method for waste cable conductors. to meet the needs of actual work

Embodiment 1

[0021] like figure 1 Shown, a kind of waste and old cable conductor regeneration method comprises the following steps:

[0022] The first step is conductor prefabrication. Firstly, the insulation layer of the recycled waste cables is stripped, and then the stripped insulation layer, steel armor, tensile reinforcement and conductors are sorted and stored separately, and then the separated cable conductors are separated again according to the material type. Store them separately, and then pass Na 2 CO 3 Soak and wash in the solution for 3 minutes, then wash it with deionized water at a temperature of 10°C and a pressure of 3.1 times atmospheric pressure, and dry the cleaned conductor with cold air for later use;

[0023] The second step is the prefabrication of the smelting furnace. Firstly, the smelting furnace is connected with the inert gas source through the gas duct, and then the nitrogen gas is continuously fed into the smelting furnace, and the oxygen content in the sme...

[0030] like figure 1 Shown, a kind of waste and old cable conductor regeneration method comprises the following steps:

[0031] The first step is conductor prefabrication. Firstly, the insulation layer of the recycled waste cables is stripped, and then the stripped insulation layer, steel armor, tensile reinforcement and conductors are sorted and stored separately, and then the separated cable conductors are separated again according to the material type. Store them separately, and then pass Na 2 SiO 3 and Na 3 PO 4 Soak in the 1:1 mixed solution for 4 minutes, then wash it with deionized water at a temperature of 10°C and a pressure of 2 times the atmospheric pressure, and dry the cleaned conductor with cold air for later use;

[0032] The second step is the prefabrication of the smelting furnace. First, the smelting furnace is connected to the inert gas source through the gas duct, and then the argon gas is continuously introduced into the smelting furnace, and the oxyg...
