Description

Technical Field

[0001] The utility model relates to the technical field of cable waste recycling, in particular to a cable production waste recycling device. Background Art

[0002] A cable is a special type of conductor. It's typically made up of several or several groups of conductors (at least two in each group) twisted together into a rope-like structure. Each group of conductors is insulated from each other and often twisted around a core. The entire structure is covered with a highly insulating sheath. Cables are often installed in the air, underground, or underwater, and are used for telecommunications or power transmission.

[0003] After being scrapped, some old cables are usually sold directly to scrap yards. Since the cable sheath and copper core in the cable are very tightly connected and difficult to separate, the conventional practice on the market is to use a stripping machine to separate the cable sheath and copper core. However, the entire process is not only highly dependent on manual intervention and has low economic benefits, but the cable sheath and copper core cannot be directly melted after being separated, which increases the complexity of the process. Utility Model Content

[0007] A plastic-copper separator is provided on one side of the secondary crushing cylinder, and a powder suction pipe is connected between the secondary crushing cylinder and the plastic-copper separator. A blower is installed on the outer wall of the powder suction pipe. A copper powder discharge hopper is installed on the bottom outer wall of the plastic-copper separator, and a plastic powder discharge pipe is fixedly connected to the top outer wall of the plastic-copper separator.

[0008] Preferably, the top cutter group and the middle cutter group, and the middle cutter group and the bottom cutter group have opposite rotation directions.

[0009] Preferably, a conveyor is fixedly connected to one side of the primary crusher, and a protective frame is welded to the top outer wall of the primary crusher.

[0010] Preferably, a symmetrically distributed connecting plate is welded to one side of the inner wall of the secondary crushing cylinder, and the outer tube and the inner rod are rotatably connected to the inner wall of the connecting plate respectively.

[0011] Preferably, a screen is provided on the outer wall of the bottom of the secondary crushing cylinder, and a bottom plate is welded to the outer wall of the screen, and the third servo motor is fixedly connected to the top outer wall of the bottom plate.

When there is a large deviation in gravity between the two, the cable protective sheath and copper core can be discharged from the plastic powder discharge pipe and the copper powder discharge hopper respectively, realizing the automatic separation of the cable protective sheath and the copper core, reducing the difficulty of separation, and both can be directly smelted, reducing the complexity of the process.

[0024] In this embodiment, the cable can be broken into small particles under the action of the primary crusher 1. When the granular cable waste falls into the secondary crushing drum 3, the first servo motor 8, the second servo motor 9 and the third servo motor 12 can respectively control the top cutting knife group 6, the middle cutting knife group 7 and the bottom cutting knife group 13 to perform rotary cutting, thereby completely crushing the cable waste without manual intervention, saving labor costs, and providing convenience for the subsequent separation of the cable protective cover and the copper core.

[0025] Example 2, refer to Figure 1A cable production waste recycling device, a plastic-copper separator 16 is provided on one side of the secondary crushing cylinder 3, and a powder suction pipe 14 is connected between the secondary crushing cylinder 3 and the plastic-copper separator 16, a blower 15 is installed on the outer wall of the powder suction pipe 14, a copper powder discharge hopper 17 is installed on the outer wall of the bottom of the plastic-copper separator 16, and a plastic powder discharge pipe 18 is fixedly connected to the outer wall of the top of the plastic-copper separator 16.

[0026] In this embodiment, under the action of the blower 15, the waste powder of the cable protective sheath and the copper core can be sucked into the plastic-copper separator 16. Since one end of the powder suction tube 14 is connected to the plastic-copper separator 16 at an angle of an oblique section, the cable protective sheath and the copper core can be sprayed into the plastic-copper separator 16 in the direction of the section of the plastic-copper separator 16. When there is a large gravity deviation between the two, the cable protective sheath and the copper core can be discharged from the plastic powder discharge pipe 18 and the copper powder discharge hopper 17 respectively, thereby realizing automatic separation of the cable protective sheath and the copper core, reducing the difficulty of separation, and both can be directly smelted, reducing the complexity of the process.

[0032] Working principle: The scrapped cables are first conveyed to the primary crusher 1 through the conveyor 19 for preliminary crushing, and the cables are crushed into small particles. After the granular cable waste falls into the secondary crushing cylinder 3, at this time, under the mutual cooperation of the first pulley group 10 and the second pulley group 11, the top cutter group 6, the middle cutter group 7 and the bottom cutter group 13 are controlled by the first servo motor 8, the second servo motor 9 and the third servo motor 12 respectively. The rotation direction of the middle cutter group 7 and the top cutter group 6 and the middle cutter group 7 are the same. On the contrary, it is beneficial to completely crush the cable waste. The cable waste is screened by the screen 22, and the waste powder of the cable protective sheath and copper core can be sucked into the plastic-copper separator 16 under the action of the blower 15. The cable protective sheath and the copper core can be sprayed into the plastic-copper separator 16 in the direction of the cross-section of the plastic-copper separator 16. By utilizing the gravity difference between the two, the cable protective sheath and the copper core can be discharged from the plastic powder discharge pipe 18 and the copper powder discharge hopper 17 respectively, and finally collected in the plastic powder collection barrel 25 and the copper powder collection barrel 24 respectively.
