Technical Field

[0001] The utility model relates to the technical field of waste rare earth fluorescent powder, in particular to a comprehensive recovery and screening device for waste rare earth fluorescent powder. Background Art

[0002] Waste rare earth phosphors refer to the phosphors remaining after discarded products containing rare earth fluorescent materials, such as used lighting equipment and display devices, are discarded. Traditional fluorescent lamps are one of the main sources of waste rare earth phosphors. The particle sizes of waste rare earth phosphors are often uneven. In subsequent recycling and processing, phosphors of different particle sizes may require different chemical leaching processes, reaction times or equipment conditions, and screening devices may be needed to screen them.

[0003] When using existing waste rare earth phosphor recovery and screening devices, their sieve plates or screens usually do not have an adjustment function. The particle size distribution of waste rare earth phosphors from different sources and batches may vary greatly. If the aperture cannot be adjusted, when processing phosphors with a large particle size range, the screening device may not be able to effectively separate phosphors of different particle sizes, resulting in certain usage limitations and reducing the screening recovery efficiency.

[0004] Therefore, a comprehensive recovery and screening device for waste rare earth phosphors is proposed. Utility Model Content

If the aperture cannot be adjusted, when processing phosphors with a large variation in particle size range, the screening device may not be able to effectively separate phosphors of different particle sizes, thereby having certain usage limitations and reducing the screening recovery efficiency.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-5 , this utility model provides a technical solution:

[0026] A comprehensive recycling and screening device for waste rare earth phosphors includes a base 1, a housing 2 fixedly connected to the top of the base 1, a screening frame 3 disposed within the housing 2, a movable slot 4 disposed within the screening frame 3, an adjustment assembly 5 disposed within the movable slot 4, and a shaking assembly 6 fixedly connected to the front side of the housing 2 for use with the screening frame 3. The shaking assembly 6 includes a drive box 601.

[0027] The adjustment assembly 5 includes a bottom plate 501, a top plate 502, a hexagonal sieve hole 503, a limit block 504, a transmission block 505 and an electric push rod 506. The bottom plate 501 is fixedly connected to the bottom of the inner wall of the screening frame 3, the top plate 502 is slidably connected to the inside of the movable groove 4 and fits together with the top of the bottom plate 501, the hexagonal sieve hole 503 is opened inside the bottom plate 501 and the top plate 502, the limit block 504 is fixedly connected to the front and rear sides of the top plate 502, the transmission block 505 is fixedly connected to the right side of the top plate 502, and the electric push rod 506 is fixedly connected to the right side of the screening frame 3 and its telescopic end is fixedly connected to the transmission block 505.

[0028] In this embodiment: by setting up the adjustment component 5, when it is necessary to adjust the aperture of the sieve hole, the electric push rod 506 can drive the transmission block 505 and the top plate 502 to perform telescopic movement. As the top plate 502 moves up and down, the overlapping area of ​​the hexagonal sieve holes 503 on the bottom plate 501 and the top plate 502 changes, so that the aperture of the hexagonal sieve hole 503 can be flexibly adjusted to meet the screening requirements of waste rare earth phosphors with different particle sizes.

[0029] Specifically, such as Figure 3 、 Figure 4 、 Figure 5 As shown, a through hole 7 is provided on the front and rear sides of the shell 2, and a support block 602 is movably connected inside the through hole 7. The side of the support block 602 close to the screening frame 3 is fixedly connected to the screening frame 3, and a protrusion 603 is fixedly connected to the top of the support block 602.

[0030] Specifically, such as Figure 5 As shown, the bottom of the inner wall of the through hole 7 is fixedly connected to a telescopic rod 604 and the top of the telescopic rod 604 is fixedly connected to the bottom of the support block 602. A return spring 605 is sleeved on the surface of the telescopic rod 604, and the return spring 605 is fixedly connected to the through hole 7 and the support block 602 on one side respectively.

[0031] Specifically, such as Figure 5 As shown, the drive box 601 is fixedly connected to the front side of the housing 2 , and the output end of the drive box 601 is fixedly connected to a cam 606 , which cooperates with the protrusion 603 .

[0032] In this embodiment: by setting the shaking component 6, when the driving box 601 is working, the cam 606 will rotate accordingly, and when the raised part of the cam 606 contacts the protrusion 603, it will apply a downward thrust to the protrusion 603, causing the support block 602 to move downward along the through hole 7; when the raised part of the cam 606 leaves the protrusion 603, the support block 602 will move upward under the elastic force of the return spring 605. Since the support block 602 is fixedly connected to the screening frame 3, the up and down movement of the support block 602 will drive the screening frame 3 to generate corresponding shaking, and the telescopic rod 604 can provide a guide for the up and down movement of the support block 602 to ensure the stability of its movement direction, and the return spring 605 can provide elastic force when the support block 602 moves upward, helping the support block 602 to quickly return to the initial position and prepare for the next shaking, thereby causing the screening frame 3 to generate periodic shaking.

[0033] Specifically, such as Figure 1 As shown, a through slot 8 is provided inside the housing 2 , and a material receiving box 9 is slidably connected inside the through slot 8 .

[0034] Specifically, such as Figure 1 As shown, the material receiving box 9 is located directly below the screening frame 3 , and a rubber handle 10 is fixedly connected to the front side of the material receiving box 9 .

[0035] In this embodiment: through the above settings, the screened phosphor can fall directly into the material receiving box 9, ensuring the accuracy and completeness of the phosphor collection, and when the material receiving box 9 is full of phosphor, the operator can easily pull it out from the through slot 8 for cleaning or replace it with a new material receiving box 9, which will not cause interference to other parts of the entire device, thereby ensuring the continuity of the recycling process.

[0036] Specifically, such as Figure 4 As shown, the front and rear sides of the inner wall of the movable slot 4 are both provided with limiting slots 11 , and the limiting blocks 504 are slidably connected inside the limiting slots 11 .

[0037] Specifically, such as Figure 1 、 Figure 2 As shown, a feed hopper 12 is fixedly connected to the top of the shell 2, and the interior of the feed hopper 12 is inclined.

[0038] In this embodiment: by setting the limit groove 11, the limit block 504 can slide in the limit groove 11, providing precise guidance for the up and down movement of the top plate 502. This guiding effect can ensure that the top plate 502 moves stably in the vertical direction, and avoids its displacement in the horizontal direction or other directions, thereby ensuring the accuracy of the aperture adjustment of the hexagonal sieve hole 503. By setting the feed hopper 12, the phosphor can flow more smoothly into the screening frame 3 under the action of its own gravity. The inclined surface reduces the resistance of the phosphor during the feeding process, avoids the accumulation of phosphor in the feed hopper 12, ensures the continuous supply of phosphor, and helps to improve the working efficiency of the entire screening device.

[0039] Working principle: When screening and recycling waste rare earth phosphors, first pour the phosphors to be screened into the feed hopper 12. Under the action of gravity, the phosphors will slide smoothly along the inclined surface into the screening frame 3. Then start the drive box 601, and the drive box 601 will drive the cam 606 to rotate. When the raised part of the cam 606 contacts the bump 603, it will apply a downward thrust to the bump 603, and then the support block 602 will move downward along the through hole 7. When the raised part of the cam 606 leaves the bump 603, the support block 602 will move upward under the elastic force of the reset spring 605, thereby driving the screening frame 3 to produce periodic shaking. This shaking will cause the phosphor particles to be continuously rearranged, making the larger Particles with small particle sizes are more likely to pass through the hexagonal sieve holes 503. After the screened phosphor passes through the hexagonal sieve holes 503, it will fall into the material receiving box 9 located directly below the screening frame 3. When the material receiving box 9 is full of phosphor, the operator can hold the rubber handle 10 on the front side of the material receiving box 9 to pull the material receiving box 9 out of the through slot 8 for cleaning or subsequent processing of the collected phosphor. When it is necessary to adjust the sieve hole diameter to adapt to phosphors of different particle sizes, start the electric push rod 506. The electric push rod 506 will drive the transmission block 505 and the top plate 502 to move on the bottom plate 501 and the top plate 502. When the top plate 502 moves, the overlapping area of ​​the hexagonal sieve holes 503 will change, thereby realizing the adjustment of the aperture of the hexagonal sieve holes 503.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
