Technical Field

[0001] This invention relates to the field of crushing equipment technology, and in particular to a crushing and sorting system. Background Technology

[0002] In the waste recycling and sorting industry, after the waste is crushed, it needs to be sorted. The sorting process is generally based on the size of the waste. Since the waste inevitably contains iron impurities, an iron removal process is often added after or before sorting.

[0003] Patent CN115415040A discloses an automobile crushing and sorting device, including a crushing box, a first crushing component, and a first screening component. First, the first magnetic mesh is adjusted to a first position and is energized. Then, the material is input from the feed inlet and crushed by the first crushing component. Larger pieces of crushed material cannot pass through the first magnetic mesh. The crushed powder material mainly includes iron powder and other material powders. At this time, because the first magnetic mesh has magnetic attraction, the iron powder is attracted by the first magnetic mesh, and other material powders fall through the first magnetic mesh.

[0004] The aforementioned existing technology requires powering off the equipment when cleaning the first magnetic screen, which is cumbersome and has low crushing efficiency. Summary of the Invention

[0005] In view of this, it is necessary to provide a crushing and sorting system to solve the technical problems of existing technology, which require powering off the equipment when cleaning the first magnetic screen, resulting in cumbersome operation and low crushing efficiency.

[0006] This invention provides a crushing and sorting system, which includes:

[0007] frame;

[0008] The first sorting cylinder is rotatably mounted on the frame along a vertical axis, and the first sorting cylinder is provided with a sorting channel extending in the vertical direction;

[0009] A separator is provided on the frame and extends from top to bottom into the sorting channel to divide the sorting channel into a first channel and a second channel. The upper end of the first channel is provided with a feed inlet.

[0010] Multiple first magnetic attraction components are arranged at intervals along the circumference of the first sorting cylinder on the outer periphery of the first sorting cylinder. Each first magnetic attraction component includes a first magnet component and a first switch component. The first magnet component is disposed on the outer side wall of the first sorting cylinder, and the first switch component is movably disposed on the first magnet component, so that the first magnet component has a first magnetic attraction state that adsorbs ferrous materials and a first demagnetization state that loses its magnetism.

[0011] A first trigger is disposed on the frame and corresponding to the second channel, so that when the first sorting cylinder rotates, the first trigger cooperates with the first switch corresponding to the second channel to drive the first switch to move, so that the first magnet assembly is in the first demagnetization state.

[0012] Optionally, the first magnet assembly includes two first magnets and a first isolator. The two first magnets are horizontally spaced apart in the first sorting cylinder, and the first isolator is disposed between the two first magnets. The first magnet assembly has an installation channel extending vertically through its middle portion.

[0013] The first switching element includes a second magnet, which is rotatably mounted in the mounting channel in a vertical direction. When the second magnet rotates to a position where its N pole and S pole correspond to the two first magnets respectively, the first magnet assembly is in the first magnetic attraction state. When the second magnet rotates to a position where its N pole and S pole correspond to the first isolator respectively, the first magnet assembly is in the first demagnetization state.

[0014] Optionally, the first switching element is further provided with a first gear, which is fixedly mounted on the second magnet;

[0015] The first trigger member has a first arc-shaped rack on the side facing the first sorting cylinder, so that when the first magnetic suction assembly rotates to the corresponding second channel, the first arc-shaped rack meshes with the first gear to drive the second magnet to rotate.

[0016] Optionally, both ends of the second magnet are rotatably connected to the first sorting cylinder;

[0017] The first magnetic attraction assembly further includes a torsion spring, which is sleeved on the outer periphery of the second magnet. One end of the torsion spring is connected to the second magnet, and the other end of the torsion spring is connected to the first sorting cylinder. When the first gear disengages from the first arc-shaped rack, the torsion spring drives the second magnet to rotate so that the N pole and S pole correspond to the two first magnets respectively.

[0018] Optionally, the first trigger member is further provided with a guide groove with the opening facing downward. The guide groove is arc-shaped, and the arc-shaped rack and the guide groove are arranged sequentially along the rotation direction of the first sorting cylinder.

[0019] The first switching element further includes a guide post disposed on the second magnet, so that when the first gear disengages from the first arc-shaped rack, the guide post extends into the guide groove to restrict the rotation of the second magnet.

[0020] Optionally, the guide post is elastically and telescopically mounted on the second magnet in the vertical direction.

[0021] Optionally, the crushing and sorting system further includes a first driving mechanism, which is disposed on the frame and connected to the first sorting cylinder to drive the first sorting cylinder to rotate.

[0022] Optionally, the crushing and sorting system further includes a second sorting cylinder, the diameter of which is smaller than that of the first sorting cylinder. The second sorting cylinder is disposed inside the first sorting cylinder and is coaxially arranged with the first sorting cylinder. The gap between the first sorting cylinder and the second sorting cylinder forms the sorting channel.

[0023] Optionally, the second sorting cylinder is rotatably arranged in the vertical direction;

[0024] The crushing and sorting system further includes multiple second magnetic attraction components and a second trigger. The multiple second magnetic attraction components are arranged at intervals along the circumference of the second sorting cylinder on the inner sidewall of the second sorting cylinder. Each second magnetic attraction component includes a second magnet component and a second switch component. The second magnet component is disposed in the second sorting cylinder, and the second switch component is movably disposed in the second magnet component, so that the second magnet component has a second magnetic attraction state that adsorbs ferrous materials and a second demagnetization state that loses its magnetism. The second trigger component is disposed in the frame and located inside the second sorting cylinder. The second trigger component is disposed corresponding to the second channel, so that when the second sorting cylinder rotates, the second trigger component cooperates with the second switch component corresponding to the second channel to drive the second switch component to move, so that the second magnet component is in the second demagnetization state.

[0025] Optionally, the crushing and sorting system further includes a second drive mechanism, which is disposed on the frame and connected to the second sorting cylinder to drive the second sorting cylinder to rotate.

[0026] Compared with the prior art, the crushing and sorting system provided by the present invention has a first sorting cylinder with a sorting channel extending vertically. A separator divides the sorting channel into a first channel and a second channel. The upper end of the first channel has a feed inlet. Multiple first magnetic attraction components are arranged at intervals along the circumference of the first sorting cylinder, and each first magnetic attraction component has a first magnetic attraction state and a first demagnetizing state. A first triggering component corresponds to the second channel and is used to cooperate with the first magnetic attraction component to put the first magnetic attraction component in the demagnetizing state. In specific use, the crushed material enters the first channel through the feed inlet, and the first magnetic attraction component corresponding to the first channel is in the magnetic attraction state, adsorbing the ferrous material in the material onto the inner wall of the first sorting cylinder and rotating with the first sorting cylinder, while other materials are discharged from the lower end of the first channel. When the ferrous material rotates to the second channel, the first magnetic attraction component engages with the first trigger, causing the first magnetic attraction component to lose its magnetic force and enter a first demagnetized state. At this time, the ferrous material is discharged from the lower end of the second channel under its own gravity. When the first magnetic attraction component disengages from the first trigger, the first magnetic attraction component regains its magnetic force and can continue to attract the ferrous material in the first channel. With this setting, the material can be screened, with the ferrous material discharged from the second channel and the remaining material discharged from the first channel. Furthermore, the side wall of the first screening cylinder is equipped with multiple first magnetic attraction components, each of which can rotate from the corresponding first channel to the corresponding second channel, thereby bringing the ferrous material in the first channel into the second channel to achieve an uninterrupted screening effect. There is no need to power off the equipment for cleaning, resulting in a high degree of automation and improved crushing efficiency.

Detailed Implementation

[0042] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0043] Please see Figures 1 to 3This crushing and sorting system includes a frame 1, a first sorting cylinder 2, a separator 3, multiple first magnetic attraction components 4, and a first trigger 5. The first sorting cylinder 2 is rotatably mounted on the frame 1 along a vertical axis, and the first sorting cylinder 2 has a sorting channel 21 extending vertically. The separator 3 is disposed on the frame 1 and extends from top to bottom into the sorting channel 21 to divide the sorting channel 21 into a first channel 211 and a second channel 212. The upper end of the first channel 211 has a feed inlet. Multiple first magnetic attraction components 4 are spaced apart around the outer periphery of the first sorting cylinder 2, and each first magnetic attraction component 4 includes a first... A magnet assembly 41 and a first switch 42 are provided. The first magnet assembly 41 is disposed on the outer side wall of the first sorting cylinder 2, and the first switch 42 is movably disposed on the first magnet assembly 41, so that the first magnet assembly 41 has a first magnetic attraction state for adsorbing ferrous materials and a first demagnetization state for losing magnetism. A first trigger 5 is disposed on the frame 1 and is disposed corresponding to the second channel 212, so that when the first sorting cylinder 2 rotates, the first trigger 5 cooperates with the first switch 42 corresponding to the second channel 212 to drive the first switch 42 to move, so that the first magnet assembly 41 is in the first demagnetization state.

[0044] The crushing and sorting system provided by this invention includes a first sorting cylinder 2 rotatably mounted on a frame 1 along a vertical axis. The first sorting cylinder 2 has a sorting channel 21 extending vertically. A separator 3 divides the sorting channel 21 into a first channel 211 and a second channel 212. A feed inlet is located at the upper end of the first channel 211. Multiple first magnetic attraction components 4 are spaced apart around the outer periphery of the first sorting cylinder 2, and each first magnetic attraction component 4 has a first magnetic attraction state and a first demagnetizing state. A first trigger 5 corresponds to the second channel 212 and is used to cooperate with the first magnetic attraction component 4, causing the first magnetic attraction component 4 to be in the first demagnetizing state. In specific use, the crushed material enters the first channel 211 through the feed inlet. The first magnetic attraction component 4 corresponding to the first channel 211 is in the first magnetic attraction state, adsorbing ferrous materials in the material onto the inner wall of the first sorting cylinder 2 and rotating with it. Other materials are discharged from the lower end of the first channel 211. When the first magnetic attraction component 4 is in the first magnetic attraction state, the ferrous materials in the material are adsorbed onto the inner wall of the first sorting cylinder 2 and rotate with it. The other materials are discharged from the lower end of the first channel 211. When the first magnetic attraction component 4 and the adsorbed iron material rotate to the second channel 212, the first magnetic attraction component 4 cooperates with the first trigger 5, causing the first magnetic attraction component 4 to lose its magnetic force and enter the first demagnetization state. At this time, the iron material is discharged from the lower end of the second channel 212 under its own gravity. When the first magnetic attraction component 4 disengages from the first trigger 5, the first magnetic attraction component 4 regains its magnetic force and can continue to adsorb the iron material in the first channel 211. With this setting, the material can be screened. The iron material is discharged from the second channel 212, and the rest of the material is discharged from the first channel 211. In addition, the side wall of the first screening cylinder is provided with multiple first magnetic attraction components 4. Each first magnetic attraction component 4 can rotate from the corresponding first channel 211 to the corresponding second channel 212, thereby bringing the iron material in the first channel 211 into the second channel 212 to achieve the effect of uninterrupted screening. There is no need to power off the equipment for cleaning. The degree of automation is high and the crushing efficiency is improved.

[0045] It should be noted that the upper end of the first channel 211 is the feed inlet, and the lower end of the first channel 211 is the first discharge outlet. The upper end of the second channel 212 is closed, and the lower end of the second channel 212 is the second discharge outlet. The separator 3 is only used to divide the sorting channel 21 into the first channel 211 and the second channel 212, and does not obstruct the movement of the iron material adsorbed on the first sorting cylinder 2. This allows the iron material to follow the rotation of the first sorting cylinder 2 from the first channel 211 into the second channel 212. Before screening, all materials enter the first channel 211 from the feed inlet. The iron material is adsorbed on the side wall of the first sorting cylinder 2, while the remaining materials pass directly through the first channel 211 and are discharged from the first discharge outlet. After the iron material enters the second channel 212, the first magnetic suction component 4 loses its magnetic force, so the iron material falls vertically and is discharged from the second discharge outlet, thus achieving the purpose of screening.

[0046] Furthermore, in order to prevent the first sorting cylinder 2 from being magnetized by the first magnetic attraction component 4, the first sorting cylinder 2 is made of a non-magnetic material, and the wall thickness of the first sorting cylinder 2 is small to avoid affecting the adsorption of ferrous materials by the first magnetic attraction component 4. In this embodiment, the first sorting cylinder 2 is made of plastic.

[0047] Further, please see Figures 8 to 10 In this embodiment, the first magnet assembly 41 includes two first magnets 411 and a first isolator 412. The two first magnets 411 are horizontally spaced apart in the first sorting cylinder 2, and the first isolator 412 is disposed between the two first magnets 411. The first magnet assembly 41 has a vertically extending mounting channel in its middle. The first switch 42 includes a second magnet 421, which is rotatably mounted in the mounting channel in the vertical direction. When the second magnet 421 rotates to the point where its N pole and S pole correspond to the two first magnets 411 respectively, the first magnet assembly 41 is in the first magnetic attraction state. When the second magnet 421 rotates to the point where its N pole and S pole correspond to the first isolator 412 respectively, the first magnet assembly 41 is in the first demagnetization state.

[0048] Specifically, the first magnet 411 is made of soft magnetic material, and the second magnets 421 are both permanent magnets. The mounting channel passes through the two first magnets 411 and the first isolation member 412. The second magnet 421 is generally strip-shaped, with its two ends along its length being the N pole and the S pole. The two ends of the second magnet 421 abut against the sidewall of the mounting channel. When the second magnet 421 rotates to the point where its N pole and S pole correspond to the two first magnets 411 respectively, that is, when the length direction of the second magnet 421 is consistent with the tangential direction of the first sorting cylinder 2, then the two ends of the length direction of the second magnet 421 correspond to the two first magnets respectively. 411. At this time, the second magnet 421 can magnetize the two first magnets 411, so that the two first magnets 411 generate magnetic force, thereby attracting ferrous materials through the two first magnets 411. When the second magnet 421 rotates 90°, that is, when the length direction of the second magnet 421 is consistent with the radial direction of the first sorting cylinder 2, the N pole and S pole of the second magnet 421 correspond to the first isolation member 412 respectively. The magnetic force of the two first magnets 411 is weak and can be ignored. At this time, ferrous materials cannot be attracted. With this setting, the first magnetic attraction component 4 can be switched between the first magnetic attraction state and the first demagnetization state by rotating the second magnet 421.

[0049] Furthermore, the first isolator 412 is made of a non-magnetic material. In this embodiment, the first isolator 412 is made of copper.

[0050] Furthermore, in order to ensure that the first magnetic attraction component 4 is in the first demagnetized state when the first sorting cylinder 2 rotates to the corresponding second channel 212, please refer to [link to relevant documentation]. Figures 8 to 10 In this embodiment, the first switch 42 is further provided with a first gear 422, which is fixedly installed on the second magnet 421; the first trigger 5 is provided with a first arc-shaped rack 51 on the side facing the first sorting cylinder 2, so that when the first magnetic suction assembly 4 rotates to the corresponding second channel 212, the first arc-shaped rack 51 meshes with the first gear 422 to drive the second magnet 421 to rotate. The first trigger 5 is located on the outside of the first magnetic attraction component 4 and is positioned corresponding to the second channel 212. When the first sorting cylinder 2 rotates, the first magnetic attraction component 4 rotates to the corresponding second channel 212, and the first gear 422 meshes with the first arc-shaped rack 51, thereby driving the second magnet 421 to rotate. As the second magnet 421 rotates, the first magnet 411 gradually loses its magnetic force, and the ferrous material falls off the cylinder wall of the first sorting cylinder 2, achieving the screening effect. Subsequently, when the rotation continues, the first gear 422 disengages from the arc-shaped rack, and the second magnet 421 rotates to its initial state, allowing the first magnet 411 to regain its magnetic force and continue to attract at the first channel 211. Each first magnetic attraction component 4 is driven by the first sorting cylinder 2 to rotate from the first channel 211 to the second channel 212, and then back from the second channel 212 to the first channel 211. This cycle repeats continuously, allowing for uninterrupted screening without the need for power-off cleaning, thus improving screening efficiency.

[0051] Further, please see Figures 8 to 10 The two ends of the second magnet 421 are rotatably connected to the first sorting cylinder 2. The first magnetic attraction assembly also includes a torsion spring 43, which is sleeved on the outer periphery of the second magnet 421. One end of the torsion spring 43 is connected to the second magnet 421, and the other end is connected to the first sorting cylinder 2. When the first gear 422 disengages from the first arc-shaped rack 51, the torsion spring 43 drives the second magnet 421 to rotate so that the N pole and S pole correspond to the two first magnets 411 respectively. This arrangement allows the second magnet 421 to rotate rapidly by 90° when the first gear 422 disengages from the first arc-shaped rack 51, causing the first magnet 411 to generate magnetic force.

[0052] Furthermore, since the sorting channel 21 is relatively long, it takes a certain amount of time for ferrous materials to fall off. To prevent ferrous materials from remaining in the second channel 212 when the torsion spring 43 drives the second magnet 421 to rotate, please refer to [link to relevant documentation]. Figure 8 , Figure 11 In this embodiment, the first trigger member 5 is further provided with a downward-facing guide groove 52. The guide groove 52 is arc-shaped, and the arc-shaped rack and the guide groove 52 are arranged sequentially along the rotation direction of the first sorting cylinder 2. The first switch member 42 also includes a guide post 423. The guide post 423 is disposed on the second magnet 421 so that when the first gear 422 disengages from the first arc-shaped rack 51, the guide post 423 extends into the guide groove 52 to restrict the rotation of the second magnet 421. In practical use, when the first gear 422 meshes with the first arc-shaped rack 51, the second magnet 421 rotates, thereby driving the guide post 423 to rotate. Just as the first gear 422 and the first arc-shaped rack 51 are about to disengage, the guide post 423 rotates into the guide groove 52. At this time, as the first screening cylinder rotates, the guide post 423 slides in the guide groove 52. The guide groove 52 limits the guide post 423, so that the second magnet 421 is kept in the state when the first gear 422 and the first arc-shaped rack 51 are about to disengage. That is, at this time, the first magnet 411 has no magnetic force, allowing time for ferrous materials to be discharged from the second channel 212. After the guide post 423 slides out of the guide groove 52, the torsion spring 43 drives the second magnet 421 to rotate, and the first magnet 411 quickly recovers its magnetic force, facilitating the next adsorption.

[0053] Furthermore, in this embodiment, a protrusion is formed on the upper side of the trigger member. The protrusion is arc-shaped, and the arc-shaped rack and the protrusion are arranged sequentially along the rotation direction of the first screening cylinder. The guide groove 52 is provided on the protrusion. The protrusion has a guide surface facing the first screening cylinder. The guide surface is gradually inclined downward in the direction away from the first screening cylinder to facilitate the cooperation between the guide post 423 and the guide groove 52.

[0054] Furthermore, when the second magnet 421 rotates, in order to avoid interference between the guide post 423 and the protrusion, the guide post 423 is elastically and telescopically mounted on the second magnet 421 in the vertical direction.

[0055] Further, please see Figures 1 to 3The crushing and sorting system further includes a first drive mechanism 6, which is mounted on the frame 1 and connected to the first sorting cylinder 2 to drive the first sorting cylinder 2 to rotate. Specifically, the first drive mechanism 6 includes a first drive gear, a first gear ring, and a first drive motor. The first gear ring is located on the outer periphery of the first screening cylinder. The first drive gear is rotatably mounted on the frame 1 in a vertical direction and meshes with the first gear ring. The first drive motor is connected to the first drive gear.

[0056] Furthermore, the farther the material is from the first magnetic attraction component 4, the weaker the attraction force of the first magnetic attraction component 4. Therefore, the magnetic attraction force is relatively small in the middle of the first screening cylinder. Please refer to [link to relevant documentation]. Figures 4 to 7 In this embodiment, the crushing and sorting system further includes a second sorting cylinder 7. The diameter of the second sorting cylinder 7 is smaller than that of the first sorting cylinder 2. The second sorting cylinder 7 is disposed inside the first sorting cylinder 2 and is coaxially arranged with the first sorting cylinder 2. The gap between the first sorting cylinder 2 and the second sorting cylinder 7 forms the sorting channel 21. With this arrangement, the material can be prevented from falling into the middle of the first sorting cylinder 2 by the obstruction of the second screening cylinder.

[0057] Furthermore, to further enhance the adsorption effect, please refer to [link / reference needed]. Figures 4 to 7 In this embodiment, the second sorting cylinder 7 is rotatably arranged in the vertical direction. The crushing and sorting system further includes multiple second magnetic attraction components 81 and a second trigger 82. The multiple second magnetic attraction components 81 are arranged at intervals along the circumference of the second sorting cylinder 7 on the inner sidewall of the second sorting cylinder 7. Each second magnetic attraction component 81 includes a second magnet component and a second switch component. The second magnet component is disposed in the second sorting cylinder 7, and the second switch component is movably disposed in the second magnet component, so that the second magnet component has a second magnetic attraction state that adsorbs ferrous materials and a second demagnetization state that loses its magnetism. The second trigger 82 is disposed in the frame 1 and located inside the second sorting cylinder 7. The second trigger 82 is disposed corresponding to the second channel 212, so that when the second sorting cylinder 7 rotates, the second trigger 82 cooperates with the second switch component corresponding to the second channel 212 to drive the second switch component to move, so that the second magnet component 421 is in the second demagnetization state. This arrangement allows ferrous materials to be adsorbed on the second screening cylinder, enhancing the adsorption effect. It should be noted that the second magnetic attraction component 81 and the second trigger component 82 have the same structure as the first magnetic attraction component 4 and the first trigger component 5, and will not be described in detail here.

[0058] Further, please see Figure 3The crushing and sorting system further includes a second drive mechanism 9, which is mounted on the frame 1 and connected to the second sorting cylinder 7 to drive the second sorting cylinder 7 to rotate. Specifically, the second drive mechanism 9 includes a second drive gear, a second gear ring, and a second drive motor. The second gear ring is located on the outer periphery of the second screening cylinder. The second drive gear is rotatably mounted on the frame 1 in a vertical direction and meshes with the second gear ring. The second drive motor is connected to the second drive gear.

[0059] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.

The second sorting cylinder is rotatably mounted in the vertical direction; The crushing and sorting system further includes multiple second magnetic attraction components and a second trigger. The multiple second magnetic attraction components are arranged at intervals along the circumference of the second sorting cylinder on the inner side wall of the second sorting cylinder. Each second magnetic attraction component includes a second magnet component and a second switch component. The second magnet component is disposed in the second sorting cylinder, and the second switch component is movably disposed in the second magnet component, so that the second magnet component has a second magnetic attraction state that adsorbs ferrous materials and a second demagnetization state that loses its magnetism. The second trigger component is disposed in the frame and located inside the second sorting cylinder. The second trigger component is disposed corresponding to the second channel, so that when the second sorting cylinder rotates, the second trigger component cooperates with the second switch component corresponding to the second channel to drive the second switch component to move, so that the second magnet component is in the second demagnetization state. The crushing and sorting system further includes a second drive mechanism, which is disposed on the frame and connected to the second sorting cylinder to drive the second sorting cylinder to rotate. The first magnet assembly includes two first magnets and a first isolator.
