Description

Technical Field

[0001] This application relates to the technical field of material separation devices, and in particular to a crushing and magnetic separation device for a combination of metals and non-metals. Background Technology

[0002] In the field of resource recycling, the recycling of metal-nonmetal composites has always been an important research direction. With the rapid development of industry, a large number of metal-nonmetal composite products are produced and used. Recycling these products after they reach the end of their service life can not only reduce resource waste but also reduce the pressure on the environment.

[0003] In the recycling of metal-nonmetal composites, manual separation is traditionally used to better recover fine metal and nonmetal fragments. Workers first pour the crushed and mixed fragments into a separation container, then use a magnet to attract the metal fragments. Once a certain amount of metal fragments has been attracted to the magnet, it is manually transferred to another container specifically for storing the metal fragments. This separation process requires repeated attempts, constantly using a magnet to attract and transfer the metal fragments to gradually separate them from the nonmetal fragments. The entire process is cumbersome and affects the efficiency of separating the metal and nonmetal fragments. Utility Model Content

[0004] The purpose of this application is to provide a crushing and magnetic separation device for metal-nonmetal composites, in order to improve the separation efficiency of fine metal fragments and fine nonmetal fragments.

[0005] This application provides a crushing and magnetic separation device for a metal-nonmetal composite, employing the following technical solution: It includes a separation box, within which a crushing component, a first collection box, a second collection box, and a magnet plate are connected. A feed inlet is located at the top of the separation box. A first conveyor belt and a second conveyor belt are rotatably connected within the separation box. The feed inlet and the first conveyor belt correspond to the crushing component, which is located between the feed inlet and the first conveyor belt. The second conveyor belt is located above the first conveyor belt and surrounds the magnet plate. The magnet plate and the first conveyor belt have overlapping vertically. The first conveyor belt is used to move nonmetallic fragments to the first collection box, and the second conveyor belt is used to move metallic fragments to the second collection box.

[0006] By adopting the above technical solution, the crushing components in the separation box crush the metal-non-metal composite material entering from the feed inlet. The fine metal and non-metal fragments fall onto the first conveyor belt under the influence of gravity. The first conveyor belt rotates and moves the fine metal and non-metal fragments. When the fine metal fragments on the first conveyor belt are directly below the magnet, the magnet attracts the fine metal fragments, causing them to be attracted onto the second conveyor belt. The first conveyor belt moves the non-metal fragments to the first collection box, and the second conveyor belt moves the fine metal fragments to the second collection box. This avoids manual separation and improves the separation efficiency of fine metal and non-metal fragments.

[0007] Optionally, the first collection box is located at the end of the first conveyor belt away from the crushing component, and the first conveyor belt is located between the crushing component and the first collection box.

[0008] By adopting the above technical solution, the first conveyor belt drives the non-metallic fragments to move to the end of the first conveyor belt away from the crushing component. The non-metallic fragments on the first conveyor belt fall into the first collection box under the influence of gravity, which facilitates the collection of non-metallic fragments.

[0009] Optionally, the second collection box is located at the end of the magnet plate away from the first collection box, and the second collection box is located below the second conveyor belt.

[0010] By adopting the above technical solution, the second conveyor belt moves the metal fragments to the end of the second conveyor belt away from the first conveyor belt. At this time, the metal fragments are no longer magnetically attracted to the magnet plate. The metal fragments fall into the second collection box under the influence of gravity, which makes it easier to collect the metal fragments.

[0011] Optionally, the separation box is connected to a paving plate, which is located between the crushing component and the first conveyor belt, or between the crushing component and the second conveyor belt, with the paving plate spaced apart from the first conveyor belt.

[0012] By adopting the above technical solution, as the first conveyor belt moves the non-metallic fragments toward the second conveyor belt, the paving plate comes into contact with the metallic and non-metallic fragments piled on the first conveyor belt, reducing accumulation and improving the separation effect of metallic and non-metallic fragments by the magnet plate.

[0013] Optionally, the separation box is inclinedly connected to a first guide plate, the inclination direction of the first guide plate is towards the opening of the first collection box, the end of the first guide plate away from the first collection box is located between the first conveyor belt and the first collection box, and the first guide plate is connected to a first brush, the first brush abutting against the first conveyor belt.

[0014] By adopting the above technical solution, during the rotation of the first conveyor belt, the non-metallic debris attached to the first conveyor belt comes into contact with the first brush bristles and falls onto the first guide plate. The first guide plate guides the non-metallic debris into the first collection box, thereby improving the collection effect of non-metallic debris.

[0015] Optionally, the separation box is inclinedly connected to a second guide plate, the inclination direction of the second guide plate is toward the opening of the first collection box, the end of the second guide plate away from the first collection box is located between the second conveyor belt and the first collection box, and the second guide plate is connected to a second brush, the second brush abutting against the second conveyor belt.

[0016] By adopting the above technical solution, during the rotation of the second conveyor belt, the non-metallic particles attached to the second conveyor belt and the metal particles come into contact with the second brush bristles and fall onto the second guide plate. The second guide plate guides the non-metallic particles into the first collection box, thereby improving the collection effect of non-metallic particles.

[0017] Optionally, the crushing assembly includes two first crushing rollers rotatably connected within the separation chamber and a drive structure for driving the two first crushing rollers to rotate in opposite directions, the drive structure being connected to the separation chamber.

[0018] By adopting the above technical solution, the metal-nonmetal composite material passes through two first crushing rollers. The driving structure drives the two first crushing rollers to rotate in opposite directions. The two first crushing rollers squeeze and crush the metal-nonmetal composite material. The metal-nonmetal composite material is crushed by the driving structure and the two first crushing rollers.

[0019] Optionally, the drive structure includes a first gear connected to each of the first crushing rollers and a first drive member for driving one of the first gears to rotate, the first drive member being connected to the separation box, and the two first gears meshing.

[0020] By adopting the above technical solution, the two first crushing rollers can be driven to rotate by the first driving component and two meshing first gears, reducing the driving force and increasing the overall structural coherence.

[0021] Optionally, the crushing assembly includes two second crushing rollers rotatably connected within the separation box and a linkage structure for driving the two second crushing rollers to rotate in opposite directions. The second crushing rollers are located between the first crushing roller and the first conveyor belt. The linkage structure is connected to the separation box, and the driving structure drives the two second crushing rollers to rotate through the linkage structure.

[0022] By adopting the above technical solution, the metal-nonmetal composite is crushed by two first crushing rollers and then by two second crushing rollers, thereby improving the crushing effect of the metal-nonmetal composite.

[0023] Optionally, the linkage structure includes a connecting gear rotatably connected to the separation box and a second gear fixedly connected to each of the second crushing rollers, with the two second gears meshing, and one of the first gears and one of the second gears meshing with the connecting gear.

[0024] By adopting the above technical solution, one of the first gears drives two second crushing rollers to rotate through a connecting gear and two second gears, reducing the driving force and increasing the overall structural coherence.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. When the metal fragments on the first conveyor belt are directly below the magnetic plate, the magnetic plate and the metal fragments are magnetically attracted, causing the metal fragments on the first conveyor belt to be attracted to the second conveyor belt. The first conveyor belt carries the non-metal fragments to the first collection box, and the second conveyor belt carries the metal fragments to the second collection box, avoiding manual separation and improving the separation efficiency of metal fragments and non-metal fragments.

[0027] 2. During the rotation of the first conveyor belt, non-metallic debris attached to the first conveyor belt comes into contact with the first brush bristles and falls onto the first guide plate. The first guide plate guides the non-metallic debris into the first collection box, thereby improving the collection effect of non-metallic debris. Attached Figure Description

[0034] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail.

[0035] This application discloses a crushing and magnetic separation device for a combination of metals and non-metals.

[0036] Combination Figure 1 , Figure 2 and Figure 3As shown in Figure 3, the system includes a separation box 1 with a feed inlet 11 at the top. The separation box 1 is connected to a crushing assembly 2, which includes two first crushing rollers 21 rotatably connected to the separation box 1, two second crushing rollers 22 rotatably connected to the separation box 1, a drive structure 23 for driving the two first crushing rollers 21 to rotate in opposite directions, and a linkage structure 24 for driving the two second crushing rollers 22 to rotate in opposite directions. The two first crushing rollers 21 are located between the feed inlet 11 and the two second crushing rollers 22, with the first crushing rollers 21 located below the feed inlet 11 and the second crushing rollers 22 located below the first crushing rollers 21. The drive structure 23 includes a first gear 231 fixedly connected to one end of each first crushing roller 21 and a first drive member 232 for driving one of the first gears 231 to rotate. The first drive member 232 is fixedly connected to the outer surface of the separation box 1 and is a motor. The side of the first gear 231 near the first drive member 232 is fixedly connected to the output end of the first drive member 232. A controller (not shown in the figure) is externally connected to the first drive member 232. The signal output end of the controller is connected to the signal input end of the first drive member 232. The two first gears 231 mesh. The linkage structure 24 includes a connecting gear 241 rotatably connected to the separation box 1 and a second gear 242 fixedly connected to each second crushing roller 22. The two second gears 242 mesh, and both one of the first gears 231 and one of the second gears 242 mesh with the second gear 242. The first driving component 232 drives the corresponding first gear 231 to rotate. The meshing of the two first gears 231 drives the two first crushing rollers 21 to rotate. The first crushing rollers 21 squeeze the metal and non-metal combination and drive the crushed metal and non-metal fragments to move towards the second gear 242. The rotation of the first gear 231 drives the two second crushing rollers 22 to rotate through the connecting gear 241 and the two second gears 242, so that the metal and non-metal fragments are squeezed again. The squeezed metal and non-metal fragments move away from the first gear 231.

[0037] Combination Figure 3 and Figure 4As shown, a first conveyor belt 3 and a second conveyor belt 4 are rotatably connected inside the separation box 1. The separation box 1 is also connected to a first drive assembly 5 and a second drive assembly 6. The first conveyor belt 3 is located below the second crushing roller 22. Fine metal and non-metal fragments fall onto the first conveyor belt 3 after passing through the second crushing roller 22. The second conveyor belt 4 is located above the first conveyor belt 3, at the end of the first conveyor belt 3 furthest from the second crushing roller 22. The ends of the first and second conveyor belts 3 and 4 have overlapping areas. A magnetic plate 12 is fixedly connected inside the separation box 1. The second conveyor belt 4 surrounds the magnetic plate 12, and the magnetic plate 12 and the first conveyor belt 3 have overlapping areas. The magnetic plate 12 magnetically attracts the fine metal fragments. The first drive assembly 5 drives the first conveyor belt 3 to rotate, and the second drive assembly drives the second conveyor belt 4 to rotate. The first drive assembly 5 and the second drive assembly 6 have the same structure, only their installation positions are different. Taking the first drive assembly 5 as an example, the first drive assembly 5 includes two rotating rollers 51 rotatably connected in the separation box 1 and a drive motor for driving one of the rotating rollers 51 to rotate. The first conveyor belt 3 is sleeved on the two rotating rollers 51. The drive motor is fixedly connected to the separation box 1. The end of one of the rotating rollers 51 near the drive motor is fixedly connected to the output end of the drive motor. The signal output end of the controller is connected to the signal input end of the drive motor. A spreading plate 13 is fixedly connected in the separation box 1. The spreading plate 13 is located between the first conveyor belt 3 and the second conveyor belt 4, and between the second crushing roller 22 and the second conveyor belt 4. The spreading plate 13 is spaced apart from the first conveyor belt 3. The spreading plate 13 is used to spread out the metal and non-metal fragments piled on the first conveyor belt 3.

[0038] Combination Figure 3 , Figure 4 and Figure 5As shown, a first collection box 7 and a second collection box 8 are installed inside the separation box 1. Both the first collection box 7 and the second collection box 8 are located below the first conveyor belt 3. The first collection box 7 is located at the end of the first conveyor belt 3 away from the second crushing roller 22, and is located between the second collection box 8 and the first conveyor belt 3. The first conveyor belt 3 carries non-metallic fine fragments into the first collection box 7. A first guide plate 14 and a second guide plate 15 are fixedly connected to the separation box 1. The first guide plate 14 is inclined, and the inclination direction of the first guide plate 14 faces the opening of the first collection box 7. The first guide plate 14 is located between the first conveyor belt 3 and the first collection box 7. The second guide plate 15 is located on the side of the first collection box 7 away from the second collection box 8. A first brush bristle 141 is fixedly connected to one end of the first guide plate 14 away from the first collection box 7. The first brush bristle 141 abuts against the lower surface of the first conveyor belt 3. The first brush bristle 141 cleans up non-metallic debris attached to the first conveyor belt 3, so that the non-metallic debris falls onto the first guide plate 14 and falls into the first collection box 7 along the first guide plate 14 under the influence of gravity. The second guide plate 15 is located on the side of the first collection box 7 away from the first guide plate 14. The second guide plate 15 is inclined, with the inclination direction of the second guide plate 15 facing the opening of the first collection box 7. The end of the second guide plate 15 away from the first collection box 7 is located between the second conveyor belt 4 and the first collection box 7. The end of the second guide plate 15 away from the first collection box 7 is fixedly connected to a second bristle 151. The second bristle 151 abuts against the lower surface of the second conveyor belt 4. The second bristle 151 cleans the non-metallic debris attached to the second conveyor belt 4, so that the non-metallic debris falls onto the second guide plate 15 and falls into the first collection box 7 along the second guide plate 15 under the influence of gravity, which facilitates the collection of non-metallic debris.

[0039] Combination Figure 3 , Figure 4 and Figure 5 As shown, the second collection box 8 is located at the end of the magnetic plate 12 away from the first conveyor belt 3. When the metal fragments on the second conveyor belt 4 are magnetically attracted to the magnetic plate 12, the metal fragments are no longer magnetically attracted to the magnetic plate 12, and the metal fragments fall into the second collection box 8 under the influence of gravity, making it easy to collect the metal fragments. The separation box 1 has an opening, and when the first collection box 7 or the second collection box 8 is full, the first collection box 7 or the second collection box 8 can be replaced through the opening.

[0040] The implementation principle of the crushing and magnetic separation device for metal and non-metal composites in this application embodiment is as follows: The metal and non-metal composites enter the separation box 1 through the feed inlet 11. The controller controls the first drive component 232 to open, and the first drive component 232 drives the corresponding first gear 231 to rotate. Through the meshing of the two first gears 231, the two first crushing rollers 21 are driven to rotate. The first crushing rollers 21 squeeze the metal and non-metal composites and drive the crushed metal and non-metal fragments to move towards the direction of the second gear 242. The first gear 231 rotates, and through the connecting gear 241 and the two second gears 242, it drives the two second crushing rollers 22 to rotate, so that the metal and non-metal fragments are squeezed again. The metal and non-metal fragments that are squeezed again fall onto the first conveyor belt 3. The first drive component 5 drives the first conveyor belt 3 to rotate. The first conveyor belt 3 drives the metal and non-metal fragments to move towards the direction of the second conveyor belt 4. During the movement, the non-metal fragments fall into the first collection box 7, which is convenient for collecting the non-metal fragments. During the movement, the metal fragments are attracted to the second conveyor belt 4 by the magnet 12. The second conveyor belt 4 drives the metal fragments to move closer to the second collection box 8. The metal fragments are no longer magnetically attracted to the magnet 12. Under the influence of gravity, the metal fragments fall into the second collection box 8, which makes it easier to collect the metal fragments.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
