Detailed implementation manners

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0027] Figure 1 shows the front view of the sorting device for screening metal particles and diaphragm scraps in the present invention, Figure 2 shows the structural schematic diagram of the sieve mesh in the present invention. The sorting device includes: The sorting device includes: a base 1, a sorting mechanism 2 and a separation mechanism 3 arranged above the base 1. The base 1 is used to place the sorting mechanism 2 and the separation mechanism 3. The sorting mechanism 2 is used to sort copper-aluminum particles and diaphragm scraps in the material, and the separation mechanism 3 is used to separate light diaphragms or powders in the material.

[0028] The sorting mechanism 2 includes: a collection box 21, a vibration motor 22, and a screen 23. The collection box 21 is fixedly connected to the screen 23. The vibration motor 22 is located below the collection box 21, and the screen 23 is located above the collection box 21. The screen 23 is used to screen metals with different radii. The collection box 21 is used to collect the screened metals. The vibration motor 22 is used to move the materials from the feeding end to the discharging end on the screen 23, and separate the metals from the light diaphragms, reducing the situation where the metals are pressed on the diaphragms.

[0029] The screen 23 includes a first sub-screen 231 and a second sub-screen 23223. The first sub-screen 231 is located on one side of the second sub-screen 23223, and the horizontal height where the first sub-screen 231 is located is lower than the horizontal height where the second sub-screen 23223 is located. The separation mechanism 3 includes an exhaust fan 31. The exhaust fan 31 is located above the second sub-screen 23223, and the input end of the exhaust fan 31 vertically faces the second sub-screen 23223. The exhaust fan 31 is used to suck the light diaphragms into the exhaust fan 31 or above the screen 23.

[0030] Furthermore, the first sub-screen 231 is connected to the second sub-screen 23223 based on a connecting plate 233, and the connecting plate 233 forms an inclined surface. The screen 23 is integrally formed. The connection between the first sub-screen 231, the connecting plate 233, and the second sub-screen 23223 is tight. Through integral forming, the internal stress of the screen 23 can reach a relatively balanced state, avoiding deformation problems caused by external factors such as temperature and humidity changes or excessive shaking force, ensuring the strength of the screen 23, and reducing the number of times of replacing the new screen 23 due to deformation.

[0031] Further, the included angle formed between the connecting plate 233 and the first sub - screen 231 is α, and the constraint range of α is 30° to 60°. The included angle between the connecting plate 233 and the first sub - screen 231 can be adjusted according to different materials. When α is 30°, the metal with a smaller radius has a smaller weight. Even if it is located on the connecting plate 233, the metal with a smaller radius will slide along the connecting plate 233 to the first sub - screen 231 under the influence of gravity, ensuring that the metal with a smaller radius can be screened at the first sub - screen 231. Similarly, when α is 40°, the metal with a smaller radius has a smaller weight. Even if it is located on the connecting plate 233, the metal with a smaller radius will slide along the connecting plate 233 to the first sub - screen 231 under the influence of gravity, ensuring that the metal with a smaller radius can be screened at the first sub - screen 231. When α is 45°, the metal with a smaller radius has a smaller weight. Even if it is located on the connecting plate 233, the metal with a smaller radius will slide along the connecting plate 233 to the first sub - screen 231 under the influence of gravity, ensuring that the metal with a smaller radius can be screened at the first sub - screen 231. When α is 50°, the metal with a smaller radius has a smaller weight. Even if it is located on the connecting plate 233, the metal with a smaller radius will slide along the connecting plate 233 to the first sub - screen 231 under the influence of gravity, ensuring that the metal with a smaller radius can be screened at the first sub - screen 231. When α is 60°, the metal with a smaller radius has a smaller weight. Even if it is located on the connecting plate 233, the metal with a smaller radius will slide along the connecting plate 233 to the first sub - screen 231 under the influence of gravity, ensuring that the metal with a smaller radius can be screened at the first sub - screen 231. That is, different angles are selected according to different materials to be screened to achieve the same effect, ensuring that the metal with a smaller radius is screened at the first sub - screen 231, and the metal with a larger radius and the diaphragm enter the second sub - screen 23223.

[0032] Further, the first sub - screen 231 is provided with first sorting holes 2311, and the second sub - screen 232 is provided with second sorting holes 2321. The radius of the first sorting holes 2311 is R1, and the radius of the second sorting holes 2321 is R2. The constraint relationship between R1 and R2 is R1 < R2. The first sorting holes 2311 and the second sorting holes 2321 are used for sorting metals of different sizes. The first sorting holes 2311 are used to screen metals with smaller radii, so that the materials with radii smaller than the first sorting holes 2311 fall from the first sorting holes 2311 to the bottom of the collection box 21. The second sorting holes 2321 are used to screen metals with larger radii, so that the metals with radii smaller than the second sorting holes 2321 fall from the second sorting holes 2321 to the bottom of the collection box 21. The first sub - screen 231 and the second sub - screen 232 screen the metals to the bottom of the collection box 21, so that all the metals in the materials fall to the bottom of the collection box 21 to distinguish the metals and the diaphragm in the materials.

[0033] It should be noted that in this embodiment, the radius of the first sorting holes 2311 is 2 - 4 mm, the radius of the second sorting holes 2321 is 6 - 8 mm, and the distribution density of the first sorting holes 2311 is larger than that of the second sorting holes 2321, which is beneficial to screening out the metals with smaller radii from the first sorting holes 2311.

[0034] Further, the sorting device is also provided with a feeding mechanism 4, which is located above the first sub - screen 231. The discharging end of the feeding mechanism 4 faces the first sub - screen 231, and the feeding mechanism 4 is inclined downward towards the first sub - screen 231, reducing the distance between the feeding mechanism 4 and the first sub - screen 231, reducing the kinetic energy of the materials falling from the feeding mechanism 4 to the screen 23, and further reducing the impact force of the materials on the screen 23, avoiding excessive impact of the materials on the screen 23, resulting in wear of the screen 23, and being beneficial to extending the service life of the screen 23. Secondly, the feeding mechanism 4 can adjust the feeding speed according to the material characteristics, so that the feeding mechanism 4 evenly and continuously transports the materials from the feeding mechanism 4 to the screen 23.

[0035] Furthermore, a connecting frame 24 is provided at the bottom of the collection box 21. The connecting frame 24 is fixedly connected to the collection box 21, and the vibration motor 22 is connected to the collection box 21 based on the connecting frame 24. The connecting frame 24 is used to transfer the vibration generated by the vibration motor 22 to the collection box 21 and the screen 23, causing the collection box 21 and the screen 23 to vibrate. The screen 23 repeatedly throws the material into the air to ensure that the material can fall to the bottom of the collection box 21 through the first sorting hole 2311 or the second sorting hole 2321. Moreover, the screen 23 vibrates repeatedly under the influence of the vibration motor 22, enabling the material to slowly travel from the first sub-screen 231 to the second sub-screen 23223. By setting a secondary screening and processing process in the same sieve body, the recovery rate of the material is effectively improved, while ensuring the safety of the operation and environmental friendliness.

[0036] Furthermore, the connecting frame 24 includes a first connecting rod 241 and a second connecting rod 242. The length of the first connecting rod 241 is D1, and the length of the second connecting rod 242 is D2. The constraint relationship between D1 and D2 is D1 < D2; and / or the vibration motor 22 is installed on the first connecting rod 241. One end of the first connecting rod 241 is connected to one end of the collection box 21 close to the feeding mechanism 4, and one end of the second connecting rod 242 is connected to one end of the collection box 21 away from the feeding mechanism 4. When the vibration motor 22 starts to vibrate, the vibration motor 22 drives the screen 23 and the collection box 21 to shake together. Since the vibration motor 22 is located on the first connecting rod 241, the shaking amplitude at the discharging end of the collection box 21 is larger, enabling metals with larger radii to move on the second sub-screen 23223, while the shaking amplitude at the feeding end of the collection box 21 is smaller, enabling metals with smaller radii to move on the first sub-screen 231, avoiding the shaking amplitude of the collection box 21 being too large, resulting in metals with smaller radii floating in the air and being inhaled by the user, which is beneficial to protecting the safety of the user.

[0037] Furthermore, a first discharge port 25 and a second discharge port 26 are provided at one end of the collection box 21 close to the second sub-screen 23223; the first discharge port 25 is located at the bottom of the collection box 21, the second discharge port 26 is located above the first discharge port 25, and the second discharge port 26 is at the same height as the second sub-screen 23223. The first discharge port 25 is used to clean the selected metals from the collection box 21, and the second discharge port 26 is used to clean the selected diaphragms from the collection box 21. By setting two different discharge ports, materials with different properties can be cleaned out from different discharge ports, accelerating the sorting efficiency.

[0038] Further, the exhaust fan 31 is connected to the cyclone separator, and the exhaust fan 31 uses negative pressure exhaust. The exhaust fan 31 is used to suck the diaphragm located on the screen 23 into the cyclone separator. The cyclone separator has a large inertial centrifugal force, which causes solid particles or droplets to be thrown to the outer wall surface for separation. The exhaust fan 31 sucks part of the diaphragm into the cyclone separator. The cyclone separator makes the diaphragm close to the inner wall according to the gravity of the diaphragm, and part of the diaphragms with heavier weight move to the first discharge port 25 along with the vibration of the vibration motor 22, avoiding the light diaphragms floating in the air during the vibration process, which may affect the operation of other devices. This is beneficial to reducing the cost of investing in labor and materials for cleaning and improving the resource utilization efficiency.

[0039] Further, a spring 27 is provided at the connection between the base 1 and the sorting mechanism 2. The spring 27 is used to buffer the vibration brought by the vibration motor 22, and the spring 27 is also used to control the engagement and separation of the base 1 and the sorting mechanism 2, ensuring the smooth transmission of power, avoiding the vibration of the collection frame 21 driving the vibration of the entire device, and being beneficial to reducing the noise generated by the vibration of the device during operation.

[0040] In summary, the sorting device for screening metal particles and diaphragm scraps of the present utility model is provided with a first sub-screen and a second sub-screen. The vibration motor vibrates the collection frame, enabling the material to move from the first sub-screen to the second sub-screen, which is beneficial for screening metal particles and diaphragm scraps with two different diameters, effectively improving the recovery rate of materials after the crushing of waste batteries. The present utility model is also provided with an exhaust fan, which sucks part of the diaphragm scraps into the corresponding device, reducing the risk of light diaphragms floating, being beneficial to reducing the cost of investing in labor and materials for cleaning, and improving the resource utilization efficiency.
