Description

Technical Field

[0001] This invention relates to the technical field of crushing mechanisms for waste copper recycling, and more specifically, to crushing mechanisms for waste copper recycling. Background Technology

[0002] The crushing mechanism for scrap copper recycling is a special crushing and supporting component for the resource recycling and processing of scrap metal. It is mainly used in the recycling process of copper-containing metal parts after the dismantling of waste household appliances. It is used to centrally crush and dismantle various scrap copper-containing components, providing pre-processing conditions for subsequent copper sorting and purification operations.

[0003] Currently, energy-efficient home appliances typically contain a significant amount of copper components. During recycling, the common practice is to first use a crusher for coarse crushing, followed by a copper granulator for further crushing and screening to complete the waste copper recovery. Existing copper granulators often employ a horizontal rotary crusher combined with a filter structure. In actual operation, the material is widely dispersed, and uneven feeding can easily lead to idling, resulting in low processing efficiency and wasted energy. Furthermore, the horizontal crushing structure struggles to completely remove impurities adhering to the copper surface, leading to residual copper in the sorted material and contamination of the finished copper product with impurities. This significantly reduces the purity of the recycled copper, making it unusable for direct reuse. Therefore, there is an urgent need to optimize and improve the existing crushing mechanism.

[0015] (III) Beneficial Effects Compared with the prior art, the present invention provides a crushing mechanism for waste copper recycling, which has the following beneficial effects: 1. This waste copper recycling crushing mechanism, by vertically arranging the crushing blade assembly, filter module, and outer shell module, and gradually reducing the diameter of the middle and lower sections of the filter screen, allows the material to gradually gather and accumulate during its descent. When the moving blades rotate, they can create a kneading effect between the accumulated material and the inner wall of the filter screen, effectively improving the separation of impurities and copper. At the same time, when the raw material, after being initially crushed by the crusher, falls, it is repeatedly patted by the rotating shaft and moving blades, which can loosen the adhering impurities and copper in advance, reducing the mutual adhesion strength between impurities and copper. This solves the problem of difficulty in peeling off waste copper wire, old cable copper cores, PVC sheaths on the surface of sheathed copper strips, insulating plastics, foamed soft plastics, and coated adhesive layers, and avoids the phenomenon of copper granules exceeding the standard due to flexible plastics adhering to copper materials, smelting coking, and substandard purity in chemical reactions.

[0016] 2. This type of crushing mechanism for waste copper recycling adopts an integrated drive structure with a single motor and a T-series spiral bevel gear commutator. It can simultaneously drive the crusher and the crushing blade assembly to operate synchronously without the need for multiple motors to drive separately, which significantly reduces power consumption and achieves energy saving. At the same time, the whole machine has a compact structure, high transmission efficiency, and short idling stroke, further reducing energy consumption and equipment operating costs, and is suitable for the continuous operation requirements of waste copper recycling.

[0017] 3. This crushing mechanism for recycling waste copper features a hinged and flip-up filter module and a threaded knob for quick disassembly and assembly. This allows the entire device to be easily opened, facilitating the cleaning, maintenance, and replacement of key components such as the filter screen, moving blades, and fixed blades. This effectively avoids material residue, blockage, and entanglement, extending the equipment's service life and improving ease of use and maintenance efficiency. Attached Figure Description

[0023] Please see Figures 1-8 A crushing mechanism for recycling waste copper includes a support module 1, a crushing blade assembly 2, a filter module 3, and a housing module 4. The crushing blade assembly 2 is rotatably connected to the inside of the support module 1. The filter module 3 is fixedly installed inside the support module 1 and located outside the crushing blade assembly 2.

A crusher 5 is provided on the upper surface of the support module 1, and a drive module 6 is fixedly connected to the middle of the upper surface of the support module 1.

[0024] Specifically, by vertically arranging the crushing blade assembly 2, the filter module 3, and the outer casing module 4, the material gradually gathers and accumulates during its descent. When the moving blade 24 rotates, it forms a kneading action with the inner wall of the filter screen 32, thereby enhancing the separation effect between the copper material and surface impurities.

[0025] Please refer to Figure 5. The support module 1 includes a support leg 11, a feeding funnel 12, a support rod 13, a top plate 14, and a first support frame 15. The feeding funnel 12 is fixedly installed on the upper end of the support leg 11, the support rod 13 is fixedly installed on the outer side of the upper surface of the feeding funnel 12, the top plate 14 is fixedly installed on the upper end of the support rod 13, and the first support frame 15 is disposed on the inner side wall of the middle part of the feeding funnel 12.

[0026] Specifically, the support leg 11 provides stable support for the entire equipment, the feeding hopper 12 receives and discharges crushed qualified materials, the support rod 13 and the top plate 14 form the upper mounting frame, and the first support frame 15 provides a stable rotation support foundation for the crushing blade assembly 2.

[0027] Please refer to Figure 4. The crushing blade assembly 2 includes a rotating shaft 21, a connecting plate 22, a first blade holder 23, and a moving blade 24. The rotating shaft 21 is rotatably connected to the inner wall of the first support frame 15 via a bearing. The upper end of the rotating shaft 21 passes through the upper surface of the top plate 14 and is rotatably connected to the inner wall of the top plate 14 via a bearing. The connecting plate 22 is fixedly installed on the outer surface of the rotating shaft 21. The first blade holder 23 is fixedly installed on one end of the connecting plate 22. The moving blade 24 is detachably connected to the inner wall of the first blade holder 23 via bolts.

[0028] Specifically, the rotating shaft 21 rotates under the drive of the drive module 6, and then drives the moving blade 24 to rotate at high speed through the connecting plate 22 and the first blade holder 23, so as to strike, shear and crush the falling material. The moving blade 24 is detachable for quick replacement after wear.

[0029] Please see Figure 6 , Figure 7 The filter module 3 includes a second support frame 31, a filter screen 32, a second feeding adapter 36, a second knife holder 37, and a fixed knife 38. A third hinge block 33 is fixedly connected to the outer surface of the second support frame 31. A first hinge block 16 is provided on the inner side wall of the support rod 13. The third hinge block 33 is hinged to the first hinge block 16 through a shaft. The filter screen 32 is fixedly installed on the inner side wall of the third hinge block 33. The second feeding adapter 36 is opened on the upper surface of the second support frame 31. There are two of each of the second support frame 31 and the filter screen 32, which are arranged symmetrically. The second knife holder 37 is fixedly installed on the outer surface of the second support frame 31. The fixed knife 38 is detachably connected to the inner side wall of the second knife holder 37 by bolts.

[0030] Specifically, the filter module 3 is rotated and opened and closed with the third hinge block 33 and the first hinge block 16 as the axis. The fixed blade 38 and the rotating moving blade 24 form a shearing pair to complete fine crushing. The filter screen 32 screens the crushed material by particle size. The symmetrical structure ensures uniform force.

[0031] Please see Figure 2 The outer casing module 4 includes a support frame 42 and an arc-shaped cover 43. A fourth hinge block 41 is fixedly connected to the outer surface of the support frame 42, and a first threaded seat 18 is fixedly connected to the outer surface of the support rod 13. The fourth hinge block 41 is hinged to the first threaded seat 18 via a shaft. The arc-shaped cover 43 is fixedly installed on the inner wall of the support frame 42. Specifically, the outer casing module 4 achieves flipping opening and closing with the fourth hinge block 41 and the first threaded seat 18 as the axis. The arc-shaped cover 43 forms a closed crushing chamber, preventing material splashing and ensuring the safety of the crushing operation.

[0032] Please see Figure 4 The connecting plate 22, the first tool holder 23 and the moving tool 24 are all provided in a number of uniformly distributed in a ring array. The connecting plates 22 are divided into at least three layers. The outer surfaces of the upper and middle connecting plates 22 are fixedly installed with flow-damping plates 25. The two flow-damping plates 25 are arranged in a circle, and the diameter of the upper flow-damping plate 25 is smaller than the diameter of the lower flow-damping plate 25.

[0033] Specifically, the multi-layered ring array of moving blades 24 improves the crushing coverage and efficiency, while the gradually changing circular flow deflectors 25 progressively reduce the material falling speed and extend the crushing and kneading time of the material in the crushing chamber.

[0034] Please see Figure 6 , Figure 7 The inner wall of the filter screen 32 is provided with a through groove corresponding to the second knife holder 37. The blade of the fixed knife 38 protrudes from the inner wall of the filter screen 32. The second knife holder 37 and the fixed knife 38 are provided with at least four blades, which are evenly distributed in a ring array. The diameter of the middle and lower section of the filter screen 32 gradually decreases. The inner bottom wall of the second support frame 31 is provided with a sloping surface 35 that is high in the middle and low at the edges.

[0035] Specifically, the fixed blade 38 protruding from the inner wall works in conjunction with the moving blade 24 to enhance the shearing effect. The diameter of the lower section of the filter screen 32 gradually changes, causing the material to gather towards the bottom. The inclined surface 35 guides the material on the bottom wall towards the filter screen 32, further enhancing the kneading and separation effect.

[0036] Please see Figure 8 The crusher 5 includes a housing 51, a crushing roller 52, and a gear 53. The housing 51 is fixedly installed on the upper surface of the top plate 14. The crushing roller 52 is rotatably connected to the inner wall of the housing 51. There are two crushing rollers 52, and their ends are meshed with each other through the gear 53. A protective cover 54 is fixedly installed on the outer surface of the housing 51 outside the gear 53.

[0037] Specifically, the two crushing rollers 52 rotate in opposite directions under the drive of the gear 53 to perform preliminary crushing of the input waste copper raw materials. The protective cover 54 protects the meshing gear 53 and improves the safety of equipment operation.

[0038] Please see Figure 8 The drive module 6 includes a motor 61 and a T-series spiral bevel gear commutator 62. The T-series spiral bevel gear commutator 62 is a three-axis configuration. The motor 61 is mounted on the outer surface of the T-series spiral bevel gear commutator 62 and the output end of the motor 61 is fixedly connected to the input end of the T-series spiral bevel gear commutator 62. A second output shaft 64 is provided on the lower surface of the T-series spiral bevel gear commutator 62, and a first output shaft 63 is provided on the outer surface of the T-series spiral bevel gear commutator 62.

[0039] Specifically, the power output of motor 61 is diverted and split by T-series spiral bevel gear commutator 62, and the power is output by the first output shaft 63 and the second output shaft 64 respectively, so as to realize the synchronous drive of two sets of crushing structures by a single motor 61, effectively saving energy.

[0040] In summary, when using the entire equipment: ensure that the threaded knob 45 securely connects the first connecting lug 34 of the filter module 3 to the second threaded seat 110, and the second connecting lug 44 of the outer casing module 4 to the first threaded seat 18. Start the motor 61 of the drive module 6. The motor 61 outputs power to the T-series spiral bevel gear commutator 62. After commutation, the first output shaft 63 drives the crushing roller 52 of the crusher 5 to rotate (the two crushing rollers 52 rotate synchronously in opposite directions through gear 53). The second output shaft 64 drives the rotating shaft 21 of the crushing blade assembly 2 to rotate. Put the waste copper-containing components into the outer casing 51 of the crusher 5. The crushing roller 52 coarsely crushes the material. The coarsely crushed material falls into the interior of the filter module 3 through the first discharge adapter 19 and the second discharge adapter 36 of the top plate 14. As the material falls, it is struck by the high-speed rotating connecting plate 22, which loosens the adhesion between impurities and copper metal beforehand. The upper slowing plate 25 slows down the speed, and the lower slowing plate 25 further decelerates the material, enhancing the impact effect. After being struck, the material undergoes centrifugal motion outward, approaching the inner wall of the filter screen 32. Subsequently, it is rapidly crushed by the cooperation of the moving blade 24 and the fixed blade 38 driven by the rotating shaft 21. The fixed blade 38 and the moving blade 24 shear and peel off impurities from the surface of the copper material, and thoroughly pulverize the waste copper raw material to a particle size that matches the pore size of the filter screen 32. After passing through the filter screen 32, the thoroughly pulverized particles enter the outer casing module 4 and then flow downwards, exiting through the discharge port at the lower end of the feeding funnel 12. The inclined surface 35 guides the material falling onto the inner bottom wall of the second support frame 31 outwards. The diameter of the lower part of the filter screen 32 gradually decreases, causing the material to gradually accumulate and form a kneading and pulverizing layer as it falls to the bottom. When the moving blade 24 rotates, it creates a kneading effect between the accumulated pulverized material and the filter screen 32, further promoting the separation of impurities adhering to the copper material. After the operation is completed, the motor 61 is turned off, the threaded knob 45 is unscrewed, and the second support frame 31 and support frame 42 are rotated around the hinge point to clean and maintain the filter screen 32, the moving blade 24, and the fixed blade 38.

[0041] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
