Description

Technical Field

[0001] The invention relates to the technical field of solid waste recycling, in particular to a granulator for recycling cable materials from polyvinyl chloride resin. Background Art

[0002] PVC plastic is one of the four basic industrial materials. The PVC resin cable material recycling granulator is a special equipment for recycling PVC resin waste for secondary use. Its main function is to mix PVC resin waste with other additives and re-granulate it into reusable cable material. It plays an important role in cable manufacturing and plastic recycling industries, not only improving resource utilization but also reducing production costs.

[0003] When the PVC resin recycling cable material granulator is recycling waste, it is necessary to first sort the metal materials in the waste and then clean them before carrying out subsequent operations. The existing sorting methods are mostly manual screening, which may leave some iron metals (screws or iron sheets) in the material, which may damage the equipment during the subsequent crushing process. The mixed metals will also affect the purity of the PVC resin raw materials. In addition, the existing PVC resin recycling cable material granulator mostly crushes all PVC resin waste at the same time. Since PVC resin waste contains flexible materials (external materials of scrap wires, flexible cables, and plug wires) and rigid materials (cable sheaths, pipes, and distribution box shells), flexible materials have high flexibility, while rigid materials have high hardness and brittleness. If they are crushed at the same time, the flexible materials may be entangled and deformed, which affects the fineness of the material and is not easy to be melted and plasticized in the subsequent process.

[0017] 2. This PVC resin recycling cable material granulator is equipped with a separation cylinder. A filter disc and a filter plate that can be accommodated above the filter disc are arranged inside the separation cylinder through a vertical shaft. After the material is initially shredded and transported to the inside of the separation cylinder, the liquid inside the separation cylinder is separated according to the density difference between the flexible PVC resin waste and the rigid PVC resin waste. The flexible PVC resin waste is located in the upper part of the liquid, and the rigid PVC resin waste is located in the lower part of the liquid for separation. After the materials are layered, the materials are taken out from the liquid respectively through the filter plate and the filter disc, and dried by a fan. The different forms of PVC resin waste are separated and processed, which is convenient for subsequent processing.

[0018] 3. This PVC resin recycling cable material granulator uses two feeding barrels and two fans to convey flexible PVC resin and rigid PVC resin to the multi-axis shredder and hammer crusher respectively for crushing. Different crushing methods are used for different forms of PVC resin waste to avoid entanglement and deformation of flexible PVC resin waste, which affects the fineness of the material.

[0030] Specifically, a metal scrap discharge port 2 is provided inside the cavity 1 on one side of the magnetic roller 29, and one side of the metal scrap discharge port 2 extends out of one side of the cavity 1. A scraper 31 is provided at the middle position inside the metal scrap discharge port 2, and a slope 32 is provided inside the metal scrap discharge port 2 below the scraper 31. After the two crushing rollers 30 cut the waste into smaller blocks, the material falls to the top of the magnetic roller 29, and the magnetic roller 29 rotates. The material and metal will contact the magnetic roller 29, and the metal will be adsorbed by the magnetic roller 29, while the polyvinyl chloride resin waste will be moved and fall into the crushing hopper 3. The metal scrap is adsorbed on the outer surface of the magnetic roller 29 and is transported to the position of the scraper 31.
