[0061] Step S1, sorting and processing the recycled waste cables according to the cable categories;

[0062] Step S2, stripping the sorted waste cables to separate the core materials and cable insulation materials of the waste cables, and crushing the cable insulation materials for pre-processing;

[0063] Step S3: The crushed pre-treated cable insulation material is washed, dried and granulated for recycling using a recycling system.

[0064] Working principle:

[0065] The crushed pre-processed waste cable insulation material is put into the conveying assembly 6 by using a feeding mechanism such as a conveying belt arranged on one side of the cleaning assembly 9. During feeding, the position of the conveying assembly 6 is adjusted by using the rotating mechanism 5, and the conveying assembly 6 is moved to the top of the cleaning assembly 9. Then, the adjusting mechanism 7 and the power mechanism 8 work together to adjust the conveying assembly 6 downward and put it into the cleaning assembly 9 to dock with the cleaning assembly 9. After that, the waste cable insulation material is put into the top opening of the conveying assembly 6. Then, the cleaning assembly 9 is used to clean and dehydrate the waste cable insulation material, and foreign matter such as sand and dust in the waste cable insulation material is cleaned. After that, the position and state of the conveying assembly 6 are adjusted by using the rotating mechanism 5, the adjusting mechanism 7 and the power mechanism 8 in the above manner, and the drying assembly 10 and the granulating assembly 11 are used to perform drying and granulating operations in sequence, so as to realize the recycling of the waste cable insulation material.

[0066] Before loading, the motor 1 on the rotating mechanism 5 is started, driving the gear 1 to rotate, and then the gear ring 1 is rotated, thereby driving the support frame 69 to rotate along the column 2. At this time, the retaining plate 1 68 slides along the guide groove 2 82 on the outer guide plate 81 on the power mechanism 8 to the position of the adapter plate 2, and the retaining plate 2 610 slides along the guide groove 1 72 on the inner guide plate 71 to the position of the adapter plate 1, so that the position of the conveying component 6 is adjusted to be just above the cleaning component 9, and then the driving unit 1 and the driving unit 2 are started, pushing the adapter plate 1 and the adapter plate 2 to move downward at the same time, so that the push-pull rod 66 and the fixed frame 67 are simultaneously When the cleaning ring 61 is in the cleaning state, the cleaning ring 61 moves downward, so that the fixing ring 61 moves downward, and then the storage frame 62 enters downward into the cleaning assembly 9 to dock with the cleaning assembly 9, until the driven tube 64 at the bottom of the storage frame 62 extends into the turntable 99 in the cleaning assembly 9 to engage with it. At the same time, when the fixing ring 61 moves downward, the push rod on the locking mechanism 611 on the fixing ring 61 is abutted by the abutment plate 92 on the cleaning box 91. When the push rod moves, it drives the pull rod 1 to move, so that the locking plate moves to the side away from the storage frame 62, and the locking plate does not engage and lock the storage frame 62, so that the storage frame 62 can rotate under the action of the turntable 99.

[0067] When cleaning and filtering, water is supplied to the cleaning box 91 through the water inlet pipe 97, and the cleaning water soaks the waste cable insulation material inside the storage frame 62. When the motor 2 is started, the driving mechanism 912 drives the driving pipe 910 and the connecting pipe 98 to rotate at the same time. When the driving pipe 910 rotates, the storage frame 62 rotates accordingly, and the storage frame 62 causes the waste cable insulation material to move inside. The storage frame 62 rotates relative to the push-pull rod 66, so that when the storage frame 62 rotates, the stirring rod pair on the push-pull rod 66 stirs and cleans the waste cable insulation material. At the same time, the isolation plate 94 is driven by the connecting pipe 98 to make the lifting blade lift the cleaning water upward, and the cleaning water flows into the outer circle of the isolation plate 94 along the water outlet hole 2 and flows to the outer ring of the isolation plate 94 and flows to the outer ring of the isolation plate 94. The waste cable insulation materials are lifted up and discharged from the water outlet hole 1, and the waste cable insulation materials are cleaned in a three-dimensional manner. After cleaning, the motor 2 stops rotating, and the cleaning box 91 is stationary for a period of time. At this time, the waste cable insulation materials float above the water surface under the buoyancy of the water, and the sand and gravel particles separated by cleaning are deposited downward on the top of the closing platform 65. When the driving unit 2 is started, the push-pull rod 66 moves upward, and the closing platform 65 does not close the driven pipe 64. The sand and gravel are discharged along the sewage pipe 911 under the action of the water flow, so as to realize the separation operation of the sand and gravel and the waste cable insulation materials. At the same time, the cleaning sewage is discharged along the water outlet pipe 96. When the cleaning water is discharged, the storage frame 62 is rotated under the action of the motor 2 to realize the dehydration operation of the waste cable insulation materials inside the storage frame 62.

[0068] After that, the dehydrated waste cable insulation material is dried by the above method. During drying, the hot air flow heated by the granulation assembly 11 enters the drying mechanism 10 along the exhaust pipe 2 to dry the waste cable insulation material.

[0069] During granulation, the dried waste cable insulation material enters the hopper 21. When the motor 4 is started, the driving shaft 23 rotates to rotate the conveying roller 24, and the waste cable insulation material in the hopper 21 falls into the storage chamber 25. When the storage chamber 25 moves to the exhaust pipe 1 26, the air in the storage chamber 25 is extracted, so that the storage chamber 25 is in a vacuum state. During subsequent rotation, the waste cable insulation material in the vacuum state falls into the storage box 31 along the connecting pipe 1 28, and is melted by the heating pipe installed in the storage box 31. At the same time, it is filtered by the filter plate 2 35 and the filter plate 3 34. Finally, the molten waste cable insulation material enters the barrel 32, and then is granulated in the granulation disk. The exhaust pipe 2 extracts the gas generated by the waste cable insulation material in the storage chamber 25 during the heating process, and the extracted high-temperature gas provides a drying heat source for the drying mechanism 10.

[0070] The present invention realizes the cleaning, dehydration, drying and granulation operations of the insulating materials after the waste cables are disassembled, so that the insulating materials in the waste cables are recycled and utilized, and the material loss is reduced to save energy. During the cleaning, the dust and sand in the insulating materials are quickly separated and filtered, and the insulating materials are dehydrated to improve the cleaning and drying efficiency of the insulating materials. In the granulation process, negative pressure vacuum treatment is adopted to discharge the air in the insulating materials and the gas in the melting process, so that bubbles are avoided in the particles of the insulating materials during the granulation process, and the granulation purity and quality of the insulating materials are improved. The hot air flow in the granulation melting process is used for drying, so that the waste heat reuse rate is achieved and energy is saved.

Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
