Description

Technical Field

[0001] This invention relates to the field of cable plastic waste recycling equipment, and in particular to a high-efficiency secondary separation system for cable rubber sheath using water flotation and magnetic attraction. Background Technology

[0002] Cables consist of a conductor and a sheath covering the conductor. During cable manufacturing, waste is inevitable. Generally, waste from various processing lines is collected for further processing. Since cable conductors are typically made of precious metal copper, they have high recycling value. The cable sheath is made of plastic, which also has recycling value, and plastic cannot be directly discarded as it would cause environmental pollution. In existing technology, wire stripping equipment is generally used to strip the cable waste, separating the conductor segments and sheath pieces for separate recycling. In actual processing, some cables use steel tape as a protective layer to protect them from mechanical damage, chemical corrosion, and environmental factors. Such cables (or other structures that may use magnetic metal materials) will, after stripping, cause the magnetic material (i.e., the aforementioned steel tape or other magnetic materials) to break into fragments, mixed with the sheath (the cable conductor can usually be separated at the wire stripping equipment). This usually requires a secondary separation of the sheath and magnetic material for separate recycling. During secondary separation, magnetic separation can generally be used. However, in practice, due to the small amount of magnetic material and the large amount of rubber, it is necessary to control the speed so that the rubber passes through the magnetic device in sequence. When the processing volume is large, it will lead to increased time consumption and the overall efficiency will not be improved. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a high-efficiency secondary separation system for cable sheathing via water buoyancy and magnetic attraction, which solves the problem that the efficiency of secondary separation of magnetic materials in cable sheathing cannot be improved in existing technologies.

[0004] According to an embodiment of the present invention, a high-efficiency secondary separation system for cable sheathing via water flotation and magnetic attraction includes a water flotation magnetic attraction separation box and a separation compaction box. A pump body is provided between the two to pump water from the separation compaction box into the water flotation magnetic attraction separation box. A magnetic attraction separation component can be detachably placed inside the upper part of the water flotation magnetic attraction separation box to attract magnetic materials. A conveying pipe is fixedly connected to the lower part of the water flotation magnetic attraction separation box, and the conveying pipe passes obliquely upward through the water flotation magnetic attraction separation box and extends to the top of the separation compaction box, where it has a downward-opening discharge pipe. A guide hopper is fixedly connected above one end of the conveying pipe inside the water flotation magnetic attraction separation box and communicates with it. The upper outer edge of the guide hopper is fixedly connected to the inner wall of the water-floating magnetic attraction separator, and several first perforations are arranged on the guide hopper; a receiving cylinder is also provided inside the separation compaction box, and several first filter holes are provided on the outer wall of the receiving cylinder; it also includes a mounting plate fixedly installed above the separation compaction box, the two ends of the mounting plate can be erected on the ground through the upright plates located on both sides of the separation compaction box, a telescopic actuator is fixedly installed on the mounting plate, the telescopic actuator has a downward output end and is fixedly connected to a pressure plate, the receiving cylinder can reciprocate between directly below the discharge pipe and directly below the pressure plate, and both the discharge pipe and the pressure plate have orthogonal projections that can be located inside the receiving cylinder. Rubber mixed with magnetic material is placed into a water-floating magnetic separator. The water in the separator causes the rubber to float, while the heavier magnetic material sinks. Once sinking, the rubber is attracted by the magnetic separator. The magnetic separator is then removed, and water from the separator is transported through a conveyor pipe to a compaction tank. During this process, the water level in the separator gradually decreases, eventually sending the rubber along with the water into the compaction tank. The rubber then falls through a discharge pipe into a receiving cylinder below, where it is trapped. Finally, the magnetic material is removed from the magnetic separator, and the rubber is reinserted into it. Then, the next batch of rubber sheets to be separated is added, and the pump is started to pump water from the separation and compaction box into the water-floating magnetic separation box. The water level in the water-floating magnetic separation box rises, allowing the rubber sheets and magnetic materials to separate a second time. This process is repeated, and a large amount of rubber sheets will accumulate in the receiving cylinder. The receiving cylinder can be moved directly under the pressure plate, and then the pressure plate is pressed down by the telescopic driver to compress the rubber sheets, reducing their volume. After removing the receiving cylinder, the compressed rubber sheets are poured out. This improves the overall efficiency and solves the problem that the efficiency of secondary separation of magnetic materials in rubber sheets cannot be improved in the existing technology.

[0005] Furthermore, the magnetic separation component includes a support cylinder that abuts against the water-floating magnetic separation box, and a pair of magnetic plates that abut against the support cylinder. The two magnetic plates form an upward-facing semicircle and are respectively fixedly connected to side plates on both sides. The side plates on both sides of the two magnetic plates abut against each other, and the magnetic plates are also provided with several second perforations.

[0006] Furthermore, the magnetic plate has a higher end with a fixed lug, and a support plate is fixedly connected to the support cylinder, with the lug resting on the support plate.

[0007] Furthermore, the magnetic suction plate has a lower end that is fixedly connected to an inclined abutment plate, and an inverted V-shaped plate that allows the two inclined abutment plates to abut against each other is also fixedly connected inside the support cylinder.

[0008] Furthermore, a pair of support plates are fixedly connected to the upper end of the support cylinder, which rests against the upper surface of the water-floating magnetic separation box.

[0009] Furthermore, the conveying pipe is provided with several third perforations on the lower wall of its lower end, and a conveying spiral extending from one end to the other is also provided inside the conveying pipe.

[0010] Furthermore, a cover plate located directly below the pressure plate is fixedly connected to the inner bottom surface of the separation compaction box.

[0011] Furthermore, the pressure plate is provided with several second filter holes.

[0012] Furthermore, the receiving cylinder includes an outer cylinder body, the upper end of which is open and the lower end is detachably connected to a base plate, and the first filter holes are distributed throughout the outer cylinder body.

[0013] Furthermore, several fifth perforations are also provided on the base plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The separation process employs a combination of magnetic separators and a water-floating magnetic separator, allowing the rubber to float rapidly while the magnetic material sinks and is then attracted by the magnetic separators. After removing the magnetic separators, the water and rubber are transported to a separation and compaction box, where the rubber is trapped in a receiving cylinder, achieving secondary separation. The water can be recycled during the separation process, thus conserving water resources. Furthermore, the rubber is compacted after separation, further reducing its volume and facilitating subsequent recycling. Overall, this method improves the efficiency of secondary separation, solving the problem of insufficient efficiency in the secondary separation of magnetic materials from rubber in existing technologies.

[0016] Through multiple rounds of rubber sheet loading, water flotation separation, and compaction, the magnetic substances contained in the rubber sheet can be separated, while the space occupied by the large rubber sheet is reduced, which is beneficial for further recycling of the rubber sheet.

[0025] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0027] In an exemplary implementation, such as Figure 1-4As shown, this embodiment provides a high-efficiency secondary separation system for cable sheathing via water flotation and magnetic attraction, comprising a water flotation magnetic attraction separation box 1 and a separation compaction box 2. A connecting pipe 3 is fixedly connected to the bottom of the water flotation magnetic attraction separation box 1, which can be used to introduce water into the water flotation magnetic attraction separation box 1 (and also to drain water from the water flotation magnetic attraction separation box after all operations are completed). A pump body 4 is installed between the water flotation magnetic attraction separation box 1 and the separation compaction box 2 to pump water from the separation compaction box 2 into the water flotation magnetic attraction separation box 1. A magnetic attraction separation component can also be detachably placed inside the upper end of the water flotation magnetic attraction separation box 1 to attract magnetic materials, including magnetic material impurities mixed in the sheathing. In a more specific embodiment, the magnetic attraction separation component includes a support cylinder 5, with two fixedly connected backing plates 6 on either side of the upper end of the support cylinder 5. The support cylinder 5 can extend into the water flotation magnetic attraction separation box 1, and the two backing plates 6 can rest against the upper surface of the water flotation magnetic attraction separation box 1, thereby making most of the lower end of the support cylinder 5... The separation unit is located inside the water-floating magnetic separation box 1. The magnetic separation component also includes a pair of magnetic plates 7 that can be arranged in a semi-circle within the support cylinder 5. Each of the two magnetic plates 7 has a second through hole, and side plates 8 are fixedly connected to both sides of each magnetic plate 7. The side plates 8 on both sides of the two magnetic plates 7 abut against each other, thus creating a semi-circular groove inside the support cylinder 5. The rubber to be separated is placed into this semi-circular groove. The magnetic plate 7 has a higher end and a lower end. At the higher end… The upper part is also fixedly connected with a lug 9, and the support cylinder 5 is also provided with a support plate 10 for the lug 9 to overlap. An inverted V-shaped plate 11 is also fixedly connected inside the support cylinder 5. The lower end of the magnetic suction plate 7 is fixedly connected with a sloping abutment plate 12. The sloping abutment plate 12 can abut against the inverted V-shaped plate 11. Specifically, the inverted V-shaped plate 11 includes two sloping plates 13, and the two sloping abutment plates 12 abut against the two sloping plates 13 respectively. In this way, the sloping plates 13 and the support plate 10 ensure that the magnetic suction plate 7 is stably set inside the support cylinder 5.In a further embodiment, a conveying pipe 14 is fixedly connected to the lower end of the water-floating magnetic separation box 1. The conveying pipe 14 passes obliquely upward through the water-floating magnetic separation box 1 and extends to the top of the separation and compaction box 2, and is provided with a discharge pipe 15 with a downward opening. A guide hopper 16 is fixedly connected to one end of the conveying pipe 14 located inside the water-floating magnetic separation box 1. The upper outer edge of the guide hopper 16 is fixedly connected to the inner wall of the water-floating magnetic separation box 1, and several first perforations 17 are arranged on the guide hopper 16. These first perforations 17 serve to connect the upper and lower parts of the water-floating magnetic separation box 1. Water is introduced through the connecting pipe 3, and the water can pass through the first perforations 17 into the guide hopper 16. Further, the water level rises and passes through the second perforation to contact the rubber, causing the rubber to float. During the process of the rubber floating, the magnetic material will be drawn downward. The magnetic plate 7 adsorbs (before this, some magnetic material has been adsorbed downwards by the magnetic plate 7, or the magnetic material can be shaken off by stirring and then adsorbed by the magnetic plate 7). After the rubber sheet floats completely (or during the floating process), the rubber sheet can be stirred to further separate all the magnetic material from the rubber sheet and move downwards to adsorb with the magnetic plate 7. Finally, the magnetic plate 7 is removed (to facilitate the removal of the magnetic plate 7, a handle 38 can be fixedly connected to the ear 9. The handle 38 extends beyond the support cylinder 5, making it convenient for the operator to hold and remove the corresponding magnetic plate 7). The magnetic material adsorbed on the magnetic plate 7 is collected, and then water is transported from the water-floating magnetic separation box 1 to the separation and compaction box 2 through the conveying pipe 14. During the process, the rubber sheet will move downwards with the water and will eventually be transported to the separation and compaction box 2 with the water.In a further embodiment, a receiving cylinder 18 is also provided inside the separation and compaction box 2, and a number of first filter holes 19 are provided on the outer wall of the receiving cylinder 18. An mounting plate 20 is also fixedly installed above the separation and compaction box 2, and the mounting plate 20 is staggered with the discharge pipe 15. A telescopic actuator 21 is fixedly installed on the mounting plate 20. The telescopic actuator 21 has a downward-facing output end and is fixedly connected to a pressure plate 22. The telescopic actuator 21 can be a cylinder, hydraulic cylinder, etc., providing power to make the pressure plate 22 vertically move. Moving vertically, and furthermore, the receiving cylinder 18 is designed to reciprocate between directly below the discharge pipe 15 and directly below the pressure plate 22, with both the discharge pipe 15 and the pressure plate 22 having orthogonal projections within the receiving cylinder 18. This allows water from the discharge pipe 15 and rubber mixed in the water to smoothly enter the receiving cylinder 18, and allows the pressure plate 22 to smoothly enter and exit the receiving cylinder 18. During the operation of the conveying pipe 14, the receiving cylinder 18 is positioned directly below the discharge pipe 15, so that the rubber transported with the water can... After the conveying pipe 14 stops operating, the magnetic suction plate 7 can be placed into the receiving cylinder 18, and the rubber to be separated can be added again. Then, the pump body 4 is started to return the pump body 4 of the separation and compaction box 2 to the water-floating magnetic suction separation box 1, repeating the previous floating process. That is, multiple rounds of rubber-floating separation-compaction are repeated. In the next round of floating, the receiving cylinder 18 can be moved directly below the pressure plate 22, and the telescopic driver 21 is started to make the pressure plate 22 press down to compact the rubber in the receiving cylinder 18, reducing the space occupied. After the pressure plate 22 returns upward, the receiving cylinder 18 returns to directly below the discharge pipe 15 to catch the next round of rubber. The water can be recycled in the whole process, which saves water resources. At the same time, the rubber is compacted after separation, which can further reduce the volume occupied by the rubber, which is conducive to subsequent recycling. Overall, the efficiency of secondary separation is improved, which solves the problem that the efficiency of secondary separation of magnetic materials in rubber is not improved in the existing technology.

[0028] In this design, the support cylinder 5 can be removed or placed into the water-floating magnetic separation box 1, which facilitates the loading of rubber. Specifically, the magnetic plate 7 can be placed inside the support cylinder 5 outside the water-floating magnetic separation box 1, then the rubber can be loaded, and then the cylinder can be sent into the water-floating magnetic separation box 1 together. Specifically, the first lifting lug 23 can be fixedly connected to the support plate 6, and lifting equipment can be used to lift and place the support cylinder 5 through the first lifting lug 23. After removing the magnetic plate 7, the support cylinder 5 can be further... The cylinder 5 is lifted out to facilitate the secondary loading of rubber sheets outside the water-floating magnetic separation box 1, which will be sent into the water-floating magnetic separation box 1 in the next round. During the lifting of the support cylinder 5, the inverted V-shaped plate 11 has an upward pointed structure, which allows the rubber sheets to be separated smoothly and not allowed to adhere to the rubber sheets during the upward movement of the support cylinder 5, so as not to have an adverse effect on the subsequent separation. The inverted V-shaped plate 11 in this solution provides an upwardly inclined support for the lower end of the magnetic plate 7, ensuring the stability of the magnetic plate 7.

[0029] like Figure 1 , 4 As shown, in a further embodiment, a conveying screw 24 extending from one end to the other is also provided inside the conveying pipe 14. More specifically, a connecting point 25 is provided between the guide hopper 16 and the conveying pipe 14, and the conveying screw 24 extends from the connecting point 25 to the discharge pipe 15. A drive motor 26 is also installed on the conveying pipe 14 to drive the conveying screw 24 to rotate. The operation of the drive motor 26 enables the conveying screw 24 to convey the water (water mixed with rubber) from the connecting point 25 to the discharge pipe 15, and then fall into the separation and compaction box 2 below. In an even further embodiment, the conveying pipe 14 is also provided with several third perforations 27 located on the lower wall surface of its lower end. When the conveying pipe 14 is running, the third perforation 27 allows water to enter the conveying pipe 14 from below. At the same time, water can also enter at the connection between the guide hopper 16 and the conveying pipe 14, so that the water level in the water-floating magnetic separation box 1 drops smoothly. When the rubber starts to enter the conveying pipe 14 from the guide hopper 16, the water level is low. At this time, the water entering through the third perforation 27 can further ensure that the rubber mixes with the water and moves upward, so as to smoothly guide it into the separation and compaction box 2. When the water level drops below the guide hopper 16, there may still be rubber in the conveying pipe 14. At this time, water can still enter through the third perforation 27, so as to ensure that the last part of the rubber is also smoothly conveyed into the separation and compaction box 2.

[0030] like Figure 1 , 5As shown, a cover plate 28 located directly below the pressure plate 22 is fixedly connected to the inner bottom surface of the separation compaction box 2. The cover plate 28 has several fourth perforations, and the side of the cover plate 28 closest to the discharge pipe 15 transitions at an incline with the inner bottom surface of the separation compaction box 2. The cover plate 28 is provided for placing the receiving cylinder 18, thus raising the bottom of the receiving cylinder 18. Specifically, when the pump body 4 is running, water is located in the separation compaction box 2 and the receiving cylinder 18. The receiving cylinder 18 can extend above the separation compaction box 2 (the portion located above the separation compaction box 2). The receiving cylinder 18 is also equipped with a first filter hole 19 to prevent excessive water from overflowing the rubber into the separation and compaction tank 2. The first filter hole 19 supplies water to flow between the separation and compaction tank 2 and the receiving cylinder 18, thereby ensuring that water flows smoothly out of the receiving cylinder 18 when the pump body 4 is running. After most of the water in the separation and compaction tank 2 is pumped to the water-floating magnetic separation tank 1, the receiving cylinder 18 can be moved onto the cover plate 28 (the inclined transition can be easily moved). The bottom of the receiving cylinder 18 is raised, and then the telescopic drive 21 is started. As the pressure plate 22 presses down, it squeezes out residual water from the rubber. This water flows downwards through the fourth perforation on the cover plate 28 and through the cover plate 28, compacting the rubber and separating the water. After the pressure plate 22 returns (i.e., returns to its initial position above the receiving cylinder 18), the receiving cylinder 18 can be removed to pour out the compacted rubber and then placed directly below the discharge pipe 15. Alternatively, the receiving cylinder 18 can be moved directly below the discharge pipe 15 for the next round of operation. More specifically, in this solution, the cover plate 22 can be used to press down the rubber. A recessed liquid collection tank 33 is provided on the separation and compaction box 2 below plate 28. The pump inlet pipe 34 of pump body 4 is connected to the bottom of the liquid collection tank 33, and the pump outlet pipe 35 is connected to the bottom of the water-float magnetic separation box. The fourth perforation provided on cover plate 28 is distributed on cover plate 28 (including the inclined transition part) so that the water in separation and compaction box 2 can enter the liquid collection tank 33. The water during the process of compacting rubber by pressure plate 22 can also enter the liquid collection tank 33. When the next round of operation is carried out, it can be ensured that the water is initially located in the liquid collection tank 33 and not in the separation and compaction box 2.

[0031] like Figure 1 , 5As shown in Figure 6, the bottom of the receiving cylinder 18 can be detachably configured. Specifically, the receiving cylinder 18 includes an outer cylinder 29, the upper end of which is open and the lower end is detachably connected to a bottom plate 30. First filter holes 19 are distributed throughout the outer cylinder 29. The pressure plate 22 has a projected image within the outer cylinder 29, ensuring normal up-and-down movement of the pressure plate 22 to compact the rubber in the receiving cylinder 18. Simultaneously, the discharge pipe 15 also has a projected image within the outer cylinder 29, ensuring smooth entry of the rubber into the receiving cylinder 18. By making the outer cylinder 29 and the bottom plate 30 detachable, it is easy to discharge the compacted rubber. More specifically, a fifth perforation is provided on the bottom plate 30 to ensure all water leaves the receiving cylinder 18. The detachable connection between the bottom plate 30 and the outer cylinder 29 can be achieved by setting screws 31 between the bottom plate 30 and the outer cylinder 29, such as using two screws 31 (or alternatively...). To prevent the bottom plate 30 from accidentally falling off during the lifting of the receiving cylinder 18, it is sufficient to provide relative fixation. After multiple rounds of floating separation operations, a thick layer of compacted rubber will accumulate inside the receiving cylinder 18 (i.e., inside the outer cylinder 29). A pair (or three) of second lifting lugs 32 can be fixedly connected to the outer wall of the outer cylinder 29. The receiving cylinder 18 can be moved to a position that is offset from the pressure plate 22 and the discharge pipe 15, and the receiving cylinder 18 can be easily lifted out of the separation compaction box 2 through the second lifting lugs 32. Then, the rubber inside can be removed after the bottom plate 30 is removed (during the removal process, the compacted rubber will not fall off immediately after the bottom plate 30 is removed; at this time, downward pressure can be applied above the receiving cylinder 18 to push it downward). After reinstalling the bottom plate 30, it can be placed in the separation compaction box 2 for the next round. Multiple receiving cylinders 18 can also be used in rotation, while the rubber is temporarily stored inside the receiving cylinder 18 and removed later during recycling.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
