Description

A waste cable peeling and crushing device

technical field

The utility model relates to the field of cables, in particular to a device for stripping and crushing waste cables.

Background technique

The utilization methods of waste and old cables include: 1. Manual peeling method: This method uses manual peeling, which has low efficiency, high cost, and poor operating environment for workers; 2. Incineration method: Incineration method is a traditional method that makes waste The plastic skin of the cable is burned, and then the copper in it is recycled, but the smoke pollution is extremely serious. At the same time, the surface of the copper wire is severely oxidized during the incineration process, which reduces the metal recovery rate. This law has been strictly prohibited by governments of various countries; 3. Mechanical stripping method: using a cable stripping machine for processing, this method still requires manual operation, is semi-mechanized, has high labor intensity, low efficiency, and is only suitable for processing thick-diameter cables; 4. Chemical method: this method has a The biggest disadvantage is that the waste liquid produced cannot be treated and has a great impact on the environment, so it is rarely used; 5. Freezing method: This method was also proposed in the 1990s, using liquid nitrogen as a refrigerant to make the waste The wire becomes brittle at extremely low temperatures, causing the plastic skin to separate from the copper wire segments.

When the cable lines are replaced and upgraded, a large number of waste cables are produced. The traditional method is to use transport vehicles for transportation. Since the waste cables have already been seriously deformed or have been cut during replacement, it is difficult to rewind and transport them directly. The cables are random Placed in the transport compartment, the transport volume is small, and it needs to be transported multiple times, and it is very troublesome to process after transport. An in-situ processing device is needed to improve the efficiency of cable recovery and transport.
