Embodiment Construction

[0031] In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0032] See Figure 1 ~ Figure 3 , a method for reclaiming metal and insulating sheaths in waste cables, comprising the following steps:

[0033] 1) Straighten out the messy waste cables manually.

[0034] 2) Send the straightened cable 1 into the rolling device 2, and the rolling device 2 rolls the straightened cable 1, and sends the flattened cable to the rotary cutting device 3, and cuts the cable Be the short section cable of 2-4mm length; Rolling device 2 can adopt such as figure 2 The structure shown in includes one or more pairs of rollers 14. The rollers 14 are supported on the frame 15 and driven by a motor. The rotational speeds of the rotating shafts 11 are matched. Rotary cutting device 3 can adopt as figure 2 The structure ...

Abstract

The invention discloses a method for recycling metal and insulating covers in waste cables. The method comprises the following steps: 1) ordering the chaotic waste cables manually; 2) sending the waste cables to a rolling device to be evened out and conveying the waste cables to a rotary cutting device to be cut into short-section cables; 3) sending the short-section cables to a screening device and separating the short-section cables into the short-section cables with diameter being more than 1mm and the short-section cables with diameter being not more than 1mm; 4) a. directly sending the short-section cables with diameter being more than 1mm to a sorting device; b. sending the short-section cables with diameter being not more than 1mm to a grinding device and sending the short-section cables to the sorting device after the insulating covers are ground; and 5) adopting the sorting device to sort the metal and insulating covers. The invention also discloses equipment for realizing the method. The method and the equipment have the following advantages and positive effects: compared with the prior art, the equipment is only provided with a rotary cutting device, thus avoiding gap and secondary cutting problems in the traditional grinding devices and reducing the tool wear, the energy consumption and the copper loss; and meanwhile, the cables with diameters being not more than 1mm are individually ground, thus improving the recycle rate of the waste cables.

Description

technical field [0001] The invention relates to a solid waste treatment method and equipment, in particular to a method and equipment for recycling metal and insulating sheaths in waste cables. Background technique [0002] Copper is an indispensable raw material for modern industry and an important strategic material. Due to the mass production of primary copper, the limited copper resources have been continuously reduced. At the same time, the production of primary copper will produce a large amount of industrial waste residue, waste liquid, waste gas, etc., which seriously pollutes the environment and destroys the ecological balance. Therefore, all countries in the world attach great importance to the recycling of scrap copper, and recycled copper has become an important source to make up for the shortage of copper resources. [0003] With the development of modern industry and communication industry, the demand for various metal wires is also increasing. At the same tim...
