Description

Technical Field

[0001] This utility model relates to the field of particle sorting technology, specifically to a copper and aluminum particle grading and sorting device with adjustable sieve holes. Background Technology

[0002] In the copper and aluminum recycling process, it is often necessary to classify and sort copper and aluminum particles so that they can be processed in a targeted manner according to different particle sizes. Currently, most copper and aluminum particle classification and sorting devices on the market use sieve plates with fixed sieve holes for sorting. However, this device has obvious defects. When it is necessary to sort copper and aluminum particles of different sizes, it is necessary to disassemble and replace the sieve plate with the corresponding sieve hole size. The operation is cumbersome and time-consuming, and it cannot achieve particle classification and screening, which seriously affects the sorting efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a copper-aluminum particle grading and sorting device with adjustable sieve holes, which has the advantage of adjustable sieve holes to achieve grading and screening.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a copper-aluminum particle grading and sorting device with adjustable sieve holes, comprising a sorting box, the top of which is connected to a feed hopper, a left fixed frame and a right fixed frame respectively installed on both sides of the inner cavity of the sorting box, an upper spring installed at the bottom of the inner cavity of the left fixed frame, a sieve plate installed at the upper end of the upper spring, a left vertical plate installed at the left end of the bottom of the sieve plate, the lower end of the left vertical plate extending through to the bottom of the left fixed frame, a right vertical plate installed through the inside of the right fixed frame, the upper end of the right vertical plate connected to the right side of the bottom of the sieve plate, a sieve bar fitted to the bottom of the sieve plate, a vibrating motor installed at the bottom of the sieve bar, a moving groove inclinedly opened on the front of the sorting box, a moving block installed at the front end of the sieve bar extending through to the outside of the moving groove, a threaded rod threadedly installed in the middle of the moving block, and a turntable installed at the right end of the threaded rod.

[0005] As a preferred embodiment, a lower spring is symmetrically installed on the bottom right side of the left fixing frame, and a support plate is installed at the lower end of the lower spring. The left end of the support plate is connected to the right side of the left vertical plate.

[0006] As a preferred embodiment, guide plates are fixedly installed on both sides below the inner cavity of the sorting box, and a collection box is pulled out and placed below the guide plates and inside the sorting box.

[0007] As a preferred embodiment, a discharge trough is provided on the right side of the sorting box and at the inclined end corresponding to the sieve plate. Vertical rods are slidably installed at both the front and rear ends of the discharge trough. A sealing baffle is fixedly installed on the outside of the vertical rods, and a handle is installed on the right side of the sealing baffle.

[0008] As a preferred embodiment, a limiting seat is fixedly installed on the right side of the front of the sorting box, and the right end of the threaded rod passes through the limiting seat and is connected to the connecting part by threads.

[0009] As a preferred embodiment, a guide rod is fixedly installed on the back of the sieve plate, and a guide block is slidably installed on the outside of the guide rod, with the lower end of the guide block connected to the rear end of the sieve bar.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses a rotating turntable to drive a threaded rod to rotate, which in turn pushes a moving block along a moving groove, thereby adjusting the spacing between the screen bars and achieving flexible adjustment of the screen hole size. It can meet the grading and sorting needs of copper and aluminum particles of different sizes without disassembling or replacing the screen plate. The operation is simple and convenient, effectively improving the sorting efficiency. The screen hole size can be adjusted to adapt to copper and aluminum particles of different sizes. A vibration motor is provided at the bottom to achieve particle grading and screening, solving the problem of poor adaptability of traditional sorting equipment and improving the sorting efficiency and accuracy of copper and aluminum particles.

[0011] 2. This utility model uses a guide plate to precisely guide small copper and aluminum particles falling through the sieve holes, preventing them from scattering and accumulating at the bottom of the sorting box and becoming difficult to clean. Instead, the inclined plate smoothly gathers the particles into the collection box, achieving centralized collection of small particles and significantly reducing subsequent cleaning workload. The sealing baffle outside the discharge trough can be flexibly controlled by the vertical sliding of the vertical rod. When the device is paused or when parameters such as sieve holes need to be adjusted, the operator only needs to pull the handle to cover the discharge trough with the sealing baffle, preventing residual materials in the sorting box from accidentally spilling out of the discharge trough, ensuring a clean operating environment and stable equipment operation, and improving the overall practicality and safety of the device.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example

[0016] Please see Figure 1 As shown, this utility model provides a copper-aluminum particle grading and sorting device with adjustable screen holes, including a sorting box 1. The top of the sorting box 1 is connected to a feed hopper 2. A left fixed frame 3 and a right fixed frame 8 are respectively installed on both sides of the inner cavity of the sorting box 1. An upper spring 4 is installed at the bottom of the inner cavity of the left fixed frame 3. A screen plate 10 is installed at the upper end of the upper spring 4. A left vertical plate 5 is installed at the left end of the bottom of the screen plate 10. The lower end of the left vertical plate 5 extends through to the bottom of the left fixed frame 3. A right vertical plate 9 is installed through inside the right fixed frame 8. The upper end of the right vertical plate 9 is connected to the right side of the bottom of the screen plate 10. A screen bar 11 is fitted to the bottom of the screen plate 10. A vibration motor 12 is installed at the bottom of the screen bar 11. A moving groove 18 is opened obliquely on the front of the sorting box 1. A moving block 19 is installed through the front end of the screen bar 11 to the outside of the moving groove 18. A threaded rod 20 is threadedly installed in the middle of the moving block 19. A turntable is installed at the right end of the threaded rod 20.

[0017] This technical solution rotates the turntable, causing the threaded rod 20 to rotate and pushing the moving block 19 to move along the moving groove 18. This adjusts the spacing between the screen bars 11, allowing for flexible adjustment of the screen hole size. Without disassembling or replacing the screen plate 10, it can meet the grading and sorting requirements of copper and aluminum particles of different sizes. The operation is simple and convenient, effectively improving the sorting efficiency. The screen hole size can be adjusted to adapt to copper and aluminum particles of different sizes. A vibration motor 12 is installed at the bottom to achieve particle grading and screening, solving the problem of poor adaptability of traditional sorting equipment and improving the sorting efficiency and accuracy of copper and aluminum particles. Example

[0018] Based on Embodiment 1, this utility model is as follows: Figure 4 As shown, a lower spring 6 is symmetrically installed on the bottom right side of the left fixed frame 3, and a support plate 7 is installed at the lower end of the lower spring 6. The left end of the support plate 7 is connected to the right side of the left vertical plate 5.

[0019] Adopting such Figure 1 The technical solution shown allows the lower spring 6 to form a bidirectional buffering cooperation with the upper spring 4 below the screen plate 10. When the vibrating motor 12 drives the screen plate 10 and screen bars 11 to vibrate, it simultaneously absorbs the impact force generated by the left vertical plate 5 rising and falling with the screen plate 10, greatly reducing the rigid collision between the left vertical plate 5 and the left fixed frame 3, and at the same time reducing the vibration fatigue damage of components such as the screen plate 10 and the left vertical plate 5, significantly extending the service life of the core screening components of the device.

[0020] Secondly, in the technical solution, guide plates 13 are fixedly installed on both sides of the lower part of the inner cavity of the sorting box 1. A collection box 14 is pulled out and placed below the guide plates 13 and inside the sorting box 1. A discharge trough 15 is opened on the right side of the sorting box 1 and corresponding to the inclined end of the screen plate 10. Vertical rods 16 are vertically slidably installed at both the front and rear ends of the discharge trough 15. A sealing baffle 17 is fixedly installed on the outside of the vertical rods 16. A handle is installed on the right side of the sealing baffle 17.

[0021] Its adoption is as follows Figure 1 The technical solution shown features a guide plate 13 that precisely guides small copper and aluminum particles falling through the sieve holes of the sieve plate 10. This prevents the particles from scattering and accumulating at the bottom of the sorting box 1, making them difficult to clean. Instead, the inclined plate guides the particles smoothly into the collection box 14, achieving centralized collection of small particles and significantly reducing subsequent cleaning workload. The sealing baffle 17 outside the discharge trough 15 can be flexibly controlled by the vertical sliding of the vertical rod 16. When the device is paused or when parameters such as the sieve holes need to be adjusted, the operator only needs to pull the handle to cover the discharge trough 15 with the sealing baffle 17. This prevents residual materials in the sorting box 1 from accidentally spilling from the discharge trough 15, ensuring a clean operating environment and stable equipment operation, and improving the overall practicality and safety of the device. Example

[0022] This utility model is as follows Figures 1-5 As shown, a limiting seat 21 is fixedly installed on the right side of the front of the sorting box 1. The right end of the threaded rod 20 passes through the limiting seat 21 and is connected to the connecting part by threads. A guide rod is fixedly installed on the back of the screen plate 10, and a guide block is slidably installed on the outside of the guide rod. At the same time, the lower end of the guide block is connected to the rear end of the screen bar 11.

[0023] Using the above technical solution, the limiting seat 21 is stably connected to the threaded rod 20 through threads, providing precise support and positioning for the threaded rod 20. This prevents the threaded rod 20 from shifting or wobbling when adjusting the spacing of the screen bars 11, ensuring that the threaded rod 20 can stably push the moving block 19 to move linearly along the moving groove 18. This, in turn, ensures the uniformity and accuracy of the spacing adjustment of the screen bars 11. The guide rod and guide block on the back of the screen plate 10 cooperate to provide reliable movement guidance for the rear end of the screen bars 11. When the screen bars 11 are adjusted along the moving groove 18 under the push of the threaded rod 20, the guide block slides synchronously along the guide rod, effectively limiting the offset trajectory of the rear end of the screen bars 11, preventing the screen bars 11 from tilting or twisting, and ensuring that the screen bars 11 always remain in a stable state of contact with the screen plate 10.

[0024] The working principle of this utility model is as follows: Before sorting copper and aluminum particles, the operator can adjust the size of the screen holes to meet the sorting requirements according to the target particle size of the particles to be sorted. First, rotate the turntable at the right end of the threaded rod 20. The turntable drives the threaded rod 20 to rotate around its own axis. Since the threaded rod 20 is threadedly connected to the moving block 19 and the moving block 19 is slidably engaged with the moving groove 18 on the front of the sorting box 1, the rotation of the threaded rod 20 will be converted into the linear movement of the moving block 19 along the moving groove 18. The movement of the moving block 19 will synchronously drive the screen bar 11 to slide along the bottom of the screen plate 10 until the screen holes formed between adjacent screen bars 11 reach the target size. After the sieve aperture is adjusted, the vibrating motor 12 is started and the copper and aluminum particles to be sorted are fed into the hopper 2. When the vibrating motor 12 is working, it generates vibration energy, which drives the sieve bar 11 and the sieve plate 10 to vibrate synchronously through the fixed connection with the sieve bar 11. Under the action of vibration, the copper and aluminum particles continuously roll and disperse on the surface of the sieve plate 10. Small copper and aluminum particles with a particle size smaller than the sieve aperture size will pass through the sieve aperture and fall down, while large copper and aluminum particles with a particle size larger than the sieve aperture size cannot pass through the sieve aperture. Under the guidance of the tilt angle of the sieve plate 10 and the action of vibration inertia, they gradually slide to the right along the inclined surface of the sieve plate 10 and are discharged through the discharge trough 15.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model 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 this utility model without departing from the essence and scope of the technical solutions of this utility model.
