Problems solved by technology

However, in order to ensure the removal effect of metal impurities, it is necessary to lay multiple magnet blocks on the surface of the conveyor belt, resulting in a higher cost for removing metal impurities
The energy consumption required to drive the magnet block to move by driving the conveyor belt is also high, which is not conducive to energy saving

Embodiment 1

[0041] refer to figure 1 , 11 , The present invention proposes a waste and old cable processing system, including a conveyor belt 1, and the system also includes a cutting device, a crushing device, a lower separation device and an upper separation device in sequence according to the process flow.

[0042] The cutting device includes a cutting knife 7, which can cut the waste power cables on the conveyor belt 1 by reciprocating up and down; the discharge side of the conveyor belt 1 is provided with a conveying device, and the conveying device is used for The waste power cable after cutting is conveyed in the crushing device; the crushing device includes a vibrating screen 16, an upper crushing mechanism and a lower crushing mechanism, and the vibrating screen 16 is located between the upper crushing mechanism and the lower crushing mechanism, and can Perform up and down reciprocating motion; the lower separation device is used to separate the copper rice grains and rubber par...

Embodiment 2

[0057] refer to image 3 , 9 The difference between this embodiment and the above-mentioned embodiments is that the upper crushing mechanism includes an upper crushing assembly, the lower crushing mechanism includes a lower crushing assembly, and the upper crushing assembly includes a plurality of top-down distribution in the third The upper crushing blade 17 on the rotating shaft 12, the lower crushing assembly includes a plurality of lower crushing blades 18 distributed on the third rotating shaft 12 from top to bottom, the number, length and density of the upper crushing blade 17 are greater than Lower pulverizing blade 18; The pulverizing filter screen 19 is also provided with in the pulverizing box, and the pulverizing screen 19 is located below the vibrating screen 16, and the pulverizing blade 17 is positioned between the vibrating screen 16 and the pulverizing box top wall. In the space, the lower crushing blade 18 is located in the space between the vibrating screen ...

Embodiment 3

[0060] refer to figure 1 The difference between this embodiment and the above-mentioned embodiments is that the conveying device includes a hopper 27 and a conveyor 26, the hopper 27 is located at the discharge end of the conveyor belt 1, and a dust filter is arranged inside the hopper 27, so The mesh hole diameter of the dust filter is smaller than the diameter of the waste electric power cable, the feed port of the conveyor 26 is located above the dust filter, and the discharge port of the conveyor 26 is connected to the inlet of the crushing box. The feed port is connected, and the feed port of the crushing box is located above the vibrating screen 16 .

[0061] Can directly enter in the hopper 27 after the waste and old cable breaks away from the conveyor belt 1, and the dust is deposited at the bottom of the hopper 27 after passing through the dust filter screen. Because the cable is preliminarily dedusted before the waste cable enters the crushing box, it can prevent th...

Abstract

The invention provides a processing system for waste cables. A cutter can cut waste power cables on a conveyor belt through vertical reciprocation; a conveying device is arranged on a discharge side of the conveyor belt and used for conveying the cut waste power cables into a smashing device; the smashing device comprises a vibrating screen, an upper smashing mechanism and a lower smashing mechanism, and the vibrating screen is located between the upper smashing mechanism and the lower smashing mechanism and can reciprocate vertically; a lower separating device is located below a discharge port of the smashing device and used for separating copper grains and rubber grains falling from the discharge port of the smashing device; an upper separating device is located above the lower separating device and used for removing magnetic metal impurities from the copper grains and the rubber grains when the copper grains and the rubber grains are separated by the lower separating device. The processing system has the effects of being high in continuity, short in processing period, convenient to operate and high in automation degree, and purity of the recovered copper grains and rubber grainsis high.

Description

technical field [0001] The invention relates to the field of cable recycling, in particular to a waste cable processing system. Background technique [0002] With the rapid development of my country's economy and society, a large number of waste cables have been eliminated. Cables are mainly composed of copper cores and sheaths. Since cables are used in a large amount each year and contain a large amount of recyclable resources, it is of great significance to recycle waste cables. [0003] The domestic waste cable recycling industry has developed rapidly in recent years, but most of them use manual stripping or incineration to recycle the copper core in waste cables. The manual stripping method has high labor intensity. In order to ensure the recycling efficiency, several workers are required to cooperate at the processing site, resulting in high labor costs. Although the method of incineration can improve the recovery efficiency, some impurities may still adhere to the sur...
