Description

Technical Field

[0001] This utility model mainly relates to the field of cable recycling technology, specifically to a waste recycling and collection device for wire and cable production. Background Technology

[0002] The production of wires and cables generates a large amount of waste containing metal cores (copper, aluminum) and non-metallic insulation layers (plastic, rubber). Direct disposal not only wastes resources but also pollutes the environment. Therefore, it is necessary to separate and reuse the waste through recycling devices. Existing wire and cable waste recycling equipment has the following shortcomings: First, the equipment layout is scattered, with crushing mechanisms, screening components, and sorting mechanisms mostly set up independently. This not only occupies a large workshop space but also requires manual material handling, resulting in low recycling efficiency. Second, the particle size of the crushed material is uneven, and the subsequent screening components lack an effective vibration-assisted structure, which easily leads to screen blockage and makes it impossible to accurately screen out materials that meet the sorting requirements, affecting the subsequent separation effect. Third, the sorting stage mostly uses simple manual sorting or single air classification, which makes it difficult to achieve complete separation of plastic particles and copper shavings. The waste after sorting contains a mixture of metals and non-metals, resulting in low recycling purity and reducing the value of resource reuse. Fourth, there is a lack of corresponding collection structures for waste of different particle sizes after screening, which easily leads to secondary mixing and further increases the difficulty of subsequent processing. To address the aforementioned issues, there is an urgent need to design a compact, precise, efficient, and convenient waste collection and recycling device for wire and cable production, in order to overcome the shortcomings of existing technologies such as resource waste, low efficiency, and incomplete separation.

[0020] See attached document Figs. 1-6A waste recycling and collection device for wire and cable production includes a frame 1. A screening component 2 and a crushing mechanism 3 are arranged sequentially from bottom to top on the frame 1. A sorting bin 4 is provided on one side of the screening component 2, and one output end of the screening component 2 is connected to the sorting bin 4. A fan 5 is installed at the bottom of the sorting bin 4. The upper end of the sorting bin 4 is connected to a cyclone separator 7 through a feeding pipe 6. The screening component 2 feeds crushed material of 3-10mm into the sorting bin 4.

[0021] The screening assembly 2 includes a screening chamber 21. The top of the screening chamber 21 is provided with a feed inlet 22. The screening chamber 21 is provided with a first screen 23 inclined to the left and a second screen 24 inclined to the right from top to bottom. The lowest end of the second screen 24 is provided with a second discharge outlet 26, which is connected to the sorting chamber 4.

[0022] The crushing mechanism 3 includes a crushing chamber 31, in which two rotating shafts 32 are rotatably installed. Multiple crushing teeth 33 are staggered on the outer peripheral walls of the two rotating shafts 32. The bottom of the crushing chamber 31 corresponds to the feed inlet 22 of the screening component 2.

[0023] The lowest end of the first screen 23 is provided with a first discharge port 25, which is located on the side wall of the screening chamber 21. The first discharge port 25 is connected to a waste collection box 9, which is used to collect the waste remaining after screening by the first screen 23.

[0024] The lower end of the second screen 24 is provided with a third discharge port 29, which is located on the side wall of the screening chamber 21. The third discharge port 29 is used to collect the waste material after being screened by the second screen 24.

[0025] A vibration motor 27 is installed at the bottom of the screening chamber 21, and the bottom of the screening chamber 21 is connected to the frame 1 by multiple springs 28.

[0026] The feeding pipe 6 includes a vertical section 61 and a horizontal section 62 connected to each other. The lower end of the vertical section 61 is connected to the upper end of the sorting bin 4, and one end of the horizontal section 62 is connected to the cyclone separator 7. Under the airflow generated by the blower 5 and the guiding action of the vertical section 61, the plastic particles can enter the feeding pipe 6 with the airflow, while the copper shavings remain in the sorting bin 4.

[0027] The cyclone separator 7 has a mixture inlet 71 on its side wall, a plastic outlet 72 at its bottom, and a gas outlet 73 at its top. The mixture inlet 71 is connected to the feeding pipe 6, and the plastic outlet 72 is connected to the plastic collection box 8.

[0028] Working principle: Waste materials generated from wire and cable production, such as scrap cables, are first fed into the crushing chamber 31 of the crushing mechanism 3. After the crushing mechanism 3 is started, the two rotating shafts 32 inside the crushing chamber 31 rotate synchronously. The crushing teeth 33, which are staggered on the outer peripheral wall of the rotating shafts 32, shear and crush the waste material. Since the bottom of the crushing chamber 31 corresponds to the feed inlet 22 of the screening component 2, the crushed material will fall directly from the bottom of the crushing chamber 31 into the screening chamber 21 of the screening component 2, without the need for manual transfer. Start the vibration motor 27 of the screening component 2. The vibration motor 27 drives the screening chamber 21 to generate high-frequency vibration. At the same time, the bottom of the screening chamber 21 is connected to the frame 1 through multiple springs 28. The springs 28 can buffer the vibration impact and enhance the vibration amplitude of the screening chamber 21 to prevent material from clogging the screen. Material falling into screening chamber 21 first comes into contact with the first screen 23 set from top to bottom: the first screen 23 is inclined to the left, and waste with a particle size larger than the screening standard will slide along the inclined surface of the first screen 23 and be discharged from the first discharge port 25 on the side wall of screening chamber 21, and finally enter the waste collection box 9 connected to the first discharge port 25 to complete the collection of large particle size waste. Materials with a particle size smaller than the aperture of the first screen 23 will fall into the second screen 24 below. The second screen 24 is tilted to the right, and fine debris with a particle size smaller than the screening standard will fall through the screen holes of the second screen 24 and be discharged from the third discharge port 29 at the bottom of the screening chamber 21 for subsequent separate processing. Fine powder <3mm is screened out to prevent fine copper shavings from being carried away by the airflow, and large pieces >10mm are screened out to prevent plastic blocks from settling due to gravity, leaving only uniform particles of 3-10mm.

[0029] Materials that meet the sorting requirements, i.e., those that need to enter the sorting chamber 4, remain on the second screen 24 and eventually slide along the inclined surface of the second screen 24 to the second discharge port 26 at its lowest end. Since the second discharge port 26 is connected to the sorting chamber 4, this part of the material directly enters the sorting chamber 4.

[0030] Start the fan 5 installed at the bottom of the sorting chamber 4 and adjust the air speed to 5-6 m / s. This air speed can carry plastic particles but cannot carry copper shavings. The fan 5 generates an upward airflow. Due to the density difference between the plastic particles and copper shavings in the waste, the plastic particles will move upward under the action of the airflow, while the copper shavings, due to their higher density, cannot be carried by the airflow and remain in the sorting chamber 4, thus achieving preliminary separation.

[0031] Plastic particles moving upward with the airflow enter the feeding pipe 6, which is connected to the upper end of the sorting chamber 4. The feeding pipe 6 includes a vertical section 61 and a horizontal section 62 connected to each other. The vertical section 61 guides the airflow and plastic particles, so that the plastic particles enter the horizontal section 62 stably and are conveyed to the cyclone separator 7 through the horizontal section 62. Plastic particles enter the cyclone separator 7 through the mixing inlet 71 on the side wall of the cyclone separator 7 with the airflow. Under the centrifugal force of the cyclone separator 7, the plastic particles separate from the airflow. The plastic particles slide down the inner wall of the cyclone separator 7 and are discharged from the plastic outlet 72 at the bottom, eventually falling into the plastic collection box 8 connected to the plastic outlet 72. The separated airflow is discharged from the gas outlet 73 at the top of the cyclone separator 7, completing the entire sorting and collection process.

[0032] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
