Description

Technical Field

[0001] The invention relates to the technical field of fluorescent powder recovery, and in particular to a fluorescent powder recovery and processing device for semiconductor light-emitting materials. Background Art

[0002] In the field of semiconductor luminescent materials, phosphors, as a key luminescent medium, are widely used in a variety of lighting and display devices such as LED lamps and display screens. However, with the upgrading of these devices, the disposal of waste fluorescent tube lamps has become an urgent problem to be solved. Fluorescent tubes contain not only recyclable phosphors, but also toxic gases such as mercury vapor. If not handled properly, they will pose a serious threat to the environment and human health.

[0003] At present, the mainstream semiconductor light-emitting material phosphor recycling and processing equipment on the market generally adopts a relatively primitive method, that is, directly crushing the waste straight tube lamps and the phosphor inside, and then recycling them through a filtering device. Although this method can achieve the recovery of phosphors to a certain extent, its operation process is cumbersome and inefficient. First, a large amount of glass fragments and metal debris will be generated during the crushing of the lamp tube. These impurities are mixed with the phosphor, which increases the difficulty of subsequent filtration and purification. Secondly, since the toxic gas inside the lamp tube is easy to overflow during the crushing process, it not only threatens the health of the operator, but also may cause pollution to the surrounding environment, increasing the safety risk during the processing process.

[0004] In addition, existing recycling equipment often requires a complex filtration system to separate phosphors and impurities after breaking the lamp tubes. This process is not only time-consuming and labor-intensive, but the filtration efficiency is often low, resulting in insufficient purity of the recovered phosphors, making it difficult to meet the requirements of subsequent reuse.

The position of the hole 22441 is slidably connected with a movable rod 2245, the outer wall of the docking rod 22442 located inside the fixed hole 22441 is sleeved with a spring 22443, one end of the spring 22443 is connected to the movable rod 2245, the outer wall of the movable rod 2245 corresponding to the position of the knife groove 22444 is hinged with a connecting rod 2246, one end of the connecting rod 2246 is hinged with a scraper 2247, the scraper 2247 extends to the inside of the knife groove 22444, and is slidably connected to the inner wall of the knife groove 22444, the end of the movable rod 2245 away from the docking rod 22442 is fixedly connected with a docking block 2248, and the docking block 224 An extrusion groove 22481 is provided at a position of the outer wall corresponding to the top groove 22445, and an extrusion plate 2249 is slidably connected inside the extrusion groove 22481. One end of the extrusion plate 2249 extends to the inside of the top groove 22445, and the other end extends to the outside of the cleaning head 2244 through the top groove 22445. The second limiting groove 23251 is inclined, one end of which is close to the outer wall of the gear ring 2325, and the other end is close to the inner wall of the gear ring 2325. The connecting bolt three is located at one end of the second limiting groove 23251 close to the outer wall of the gear ring 2325. The diameter of the cleaning head 2244 is smaller than the diameter of the inner wall of the lamp tube, and the scraper 2247 is an evenly distributed inclined knife.

[0039] By adopting the above technical solution, the diameter of the cleaning head 2244 is designed to be smaller than the diameter of the inner wall of the lamp tube to ensure that it can smoothly enter the interior of the lamp tube. Under normal conditions, the blade portion of the scraper 2247 is stored in the knife groove 22444, and the force of the spring 22443 keeps the movable rod 2245 in a position close to the fixing hole 22441. The diameter of the sleeve 2243 matches the diameter of the inner wall of the lamp tube, allowing the sleeve 2243 to move close to the inner wall of the lamp tube, thereby effectively collecting the scraped fluorescent powder. In addition, the extrusion groove 22481 in the docking block 2248 will squeeze one end of the extrusion plate 2249 out of the top groove 22445 under normal circumstances. This design helps the scraper 2247 to automatically unfold when it contacts the inner wall of the lamp tube. The scraper 2247 is evenly distributed along the circumferential outer surface of the cleaning head 2244 and is inclined. This layout enables it to better fit the inner wall of the lamp tube, thereby achieving a more efficient fluorescent powder scraping effect.

[0040] A placing table 14 is provided at the top of the main body 1 between the powder cleaning chamber 1 21 and the powder cleaning chamber 2 22, a collecting chamber 11 is provided inside the main body 1, a feeding trough 12 is provided at the top of the collecting chamber 11 near the powder cleaning chamber 1 21 and the powder cleaning chamber 2 22, telescopic rod 13 is provided at both ends of the main body 1 near the powder cleaning chamber 1 21 and the powder cleaning chamber 2 22, the output end of the telescopic rod 13 passes through the main body 1 and is connected with the powder cleaning chamber 1 21 and the powder cleaning chamber 2 22, an exhaust hole 211 connected with the exhaust mechanism is provided at the top of the powder cleaning chamber 1 21, a knocking assembly 221 is provided above the powder cleaning assembly 224 inside the powder cleaning chamber 22, a screw drive assembly 222 is provided above the motor assembly 223 inside the powder cleaning chamber 22, and the screw drive assembly 222 is connected to the motor assembly 223.

[0041] By adopting the above technical scheme, the feed trough 12 located below the second powder cleaning chamber 22 receives broken glass and lamp tube heads, and the feed trough 12 located below the first powder cleaning chamber 21 receives lamp tube heads and fluorescent powder. The exhaust mechanism absorbs the toxic gas leaked after the lamp tube is opened through the exhaust hole 211 at the top of the first powder cleaning chamber 21. The knocking component 221 is used to smash the lamp tube after the powder cleaning component 224 pulls the lamp tube into the second powder cleaning chamber 22. The screw drive component 222 is used to control the motor component 223 to drive the powder cleaning component 224 to move inside the second powder cleaning chamber 22, so that the powder cleaning component 224 can scrape the fluorescent powder on the inner wall of the lamp tube.

[0042] A sealing and cutting assembly 23 is symmetrically arranged at one end where the powder cleaning chamber 1 21 and the powder cleaning chamber 22 are close to each other. The powder cleaning assembly 224 and the sealing and cutting assembly 23 are on the same axial line. The sealing and cutting assembly 23 includes a sealing ring 231 and a cutting ring 232. The sealing ring 231 includes a fixing ring 1 2311 fixedly connected to the inner walls of the powder cleaning chamber 1 21 and the powder cleaning chamber 22. A fixing plate 2312 is fixedly connected to the fixing ring 1 2311 near the middle position. A limiting ring 2316 is rotatably connected to a position near the fixing plate 2312 in the fixing ring 1 2311. A rubber sheet 2313 is fixedly connected to a position near the limiting ring 2316 in the fixing ring 1 2311. An installation groove 1 2314 is provided in the rubber sheet 2313. A pulling rod 2315 is arranged in the installation groove 1 2314. One end of the pulling rod 2315 extends to the outside of the rubber sheet 2313, and one end of the pulling rod 2315 located on the outside is arranged There is a docking bolt 1, a limiting groove 1 23161 is provided on the outer wall of the limiting ring 2316 corresponding to the position of the docking bolt 1, one end of the docking bolt 1 extends to the inside of the limiting groove 1 23161 and is slidably connected with its inner wall, a docking groove 23121 is provided on the outer wall of the limiting ring 2316, and a docking bolt 2 is provided on the outer wall of the limiting ring 2316 corresponding to the position of the docking groove 23121, one end of the docking bolt 2 extends to the inside of the docking groove 23121, and the fixing plate 2312 is away from the limiting ring A telescopic rod 2317 is hinged on one side of 2316, and the output end of the telescopic rod 2317 is hinged to the docking bolt 2. The diameter of the central circular hole of the rubber sheet 2313 is smaller than the diameter of the lamp tube in a normal state. The limiting groove 1 23161 is inclined, with one end close to the outer wall of the circumference of the limiting ring 2316 and the other end close to the inner wall of the circumference of the limiting ring 2316. In a normal state, the docking bolt 1 is in the limiting groove 1 23161, close to the end of the inner wall of the circumference of the limiting ring 2316.

[0043] By adopting the above technical solution, when the limiting groove 1 23161 moves, it will squeeze the docking bolt 1, causing the docking bolt 1 to be displaced, thereby driving the pull rod 2315 to move. This movement will expand the diameter of the central circular hole of the rubber sheet 2313, making it larger than the diameter of the lamp tube. Subsequently, as the assembly moves, the end of the lamp tube can enter the interior of the sealing cutting assembly 23 through the enlarged central circular hole. When both ends of the lamp tube are sleeved, the telescopic rod 2317 will push the docking bolt 2 to make the limiting ring 2316 rotate in the opposite direction. At this time, the limiting groove 1 23161 squeezes the docking bolt 1 again to reset the pull rod 2315. After the pull rod 2315 is reset, it will drive the central circular hole of the rubber sheet 2313 to fit closely with the outer wall of the lamp tube to effectively prevent the leakage of toxic gases.

[0044] The cutting ring 232 includes a second fixing ring 2321 fixedly connected to the first fixing ring 2311, a mounting ring 2322 is rotatably connected to the side of the second fixing ring 2321 near the first fixing ring 2311, a mounting groove 2323 is provided on the outer circumference of the mounting ring 2322, a cutter 2324 is slidably connected to the inner circumference of the mounting groove 2323, one end of the cutter 2324 extends to the outside of the mounting ring 2322, and a connecting bolt 3 is provided on the outer end, and the outer circumference of the mounting ring 2322 near the mounting groove 2323 is provided with a connecting bolt 3. The position of the groove 2323 is rotatably connected with a gear ring 2325, and a limiting groove 23251 is provided on the outer wall of the gear ring 2325 near the connecting bolt 3. The inside of the fixed ring 2321 near the gear ring 2325 is rotatably connected with a gear 2326, and the gear ring 2325 is meshingly connected with the gear 2326. A driving motor 2327 is provided on the outside of the fixed ring 2321 near the gear 2326, and the output end of the driving motor 2327 passes through the fixed ring 2321 and is fixedly connected with the gear 2326.

[0045] By adopting the above technical solution, when the driving motor 2327 is started and the gear ring 2325 is driven to rotate through the gear 2326, the rotation of the gear ring 2325 will squeeze the connecting bolt 3 by using the inclined design of the second limiting groove 23251. This squeezing action prompts the connecting bolt 3 to drive the blade of the cutter 2324 to extend out from the second mounting groove 2323 and gradually approach the outer wall of the lamp tube. Once the blade of the cutter 2324 is close to the outer wall of the lamp tube, the cutter 2324 and the connecting bolt 3 cannot move further. At this time, the connecting bolt 3 is stuck in the second limiting groove 23251, forcing the cutter 2324 to rotate only with the gear ring 2325. As the gear ring 2325 continues to rotate, the cutter 2324 will rotate around the outer wall of the lamp tube to cut. In this process, since the connecting bolt 3 is continuously squeezed by the second limiting groove 23251, pressure is applied to the cutter 2324, and this pressure continuously applies cutting force to the lamp tube through the cutter 2324 until the end of the lamp tube is cut off.

[0046] The working principle and use process of the embodiment of the present invention are as follows:

[0047] In normal state, the diameter of the central circular hole of the rubber sheet 2313 is smaller than the diameter of the lamp tube. The limiting groove 23161 is inclined, with one end close to the outer wall of the limiting ring 2316 and the other end close to the inner wall of the limiting ring 2316. In normal state, the docking bolt 1 is in the limiting groove 23161 close to the end of the inner wall of the limiting ring 2316.

[0048] The second limiting groove 23251 is inclined, with one end close to the outer wall of the toothed ring 2325 and the other end close to the inner wall of the toothed ring 2325. When the cutter 2324 is in a normal state, the blade part is located inside the second mounting groove 2323, and the connecting bolt three is located at one end of the second limiting groove 23251 close to the outer wall of the toothed ring 2325.

[0049] The diameter of the cleaning head 2244 is smaller than the diameter of the inner wall of the lamp tube. When the scraper 2247 is in normal state, the blade part of the scraper 2247 is retracted inside the blade groove 22444. At the same time, the spring 22443 will pull the movable rod 2245 to a position close to the fixing hole 22441. The diameter of the sleeve 2243 is close to the diameter of the inner wall of the lamp tube, so that the sleeve 2243 can move along the inner wall of the lamp tube. At the same time, the extrusion groove 22481 in the docking block 2248 is in a position to squeeze one end of the extrusion plate 2249 out of the top groove 22445. The scraper 2247 is an inclined knife evenly distributed along the circumferential outer surface of the cleaning head 2244, so that it can better fit the inner wall of the lamp tube and its scraping effect is better.

[0050] The lamp tube is placed on the top of the placement table 14 for clamping and fixing, and then the telescopic rod 13 synchronously pushes the powder cleaning chamber 1 21 and the powder cleaning chamber 2 22 to move toward the lamp tube synchronously. The movement of the powder cleaning chamber 1 21 and the powder cleaning chamber 2 22 will drive the sealing cutting assembly 23 to move toward the end of the lamp tube. While the sealing cutting assembly 23 moves, the output end of the telescopic rod 2 2317 pulls the docking bolt 2. After the docking bolt 2 is pulled, it will drive the limit ring 2316 to rotate. The movement of the limit ring 2316 will drive the limit groove 1 23161 to move. The movement of the limit groove 1 23161 will squeeze the connecting bolt 1 to produce displacement, and the pulling rod 2315 is driven to move through the connecting bolt 1. The pulling rod The movement of 2315 will pull the central circular hole of the rubber sheet 2313 to become larger, making the diameter of the central circular hole larger than the diameter of the lamp tube, and then follow the movement to make the end of the lamp tube pass through the central circular hole of the rubber sheet 2313 and enter the interior of the sealing and cutting assembly 23. When the two ends of the lamp tube are installed, the telescopic rod 2317 pushes the docking bolt 2 to make the limiting ring 2316 rotate in the opposite direction, and then squeezes the connecting bolt 1 through the limiting groove 1 23161 to reset the pulling rod 2315. When the pulling rod 2315 is reset, it will drive the central circular hole of the rubber sheet 2313 to fit tightly against the outer wall of the lamp tube, and the rubber sheet 2313 will fit tightly against the outer wall of the lamp tube to prevent the leakage of toxic gases after the lamp tube is cut off.

[0051] When the central circular hole of the rubber sheet 2313 is in close contact with the outer wall of the lamp tube, the driving motor 2327 drives the toothed ring 2325 to rotate through the gear 2326. The rotation of the toothed ring 2325 will squeeze the connecting bolt 3 through the limiting groove 23251, and the connecting bolt 3 will drive the blade of the cutter 2324 to extend from the mounting groove 2323 to the outer wall of the lamp tube. When the blade is in close contact with the outer wall of the lamp tube, the cutter 2324 and the connecting bolt 3 cannot move. The connecting bolt 3 is stuck in the limiting groove 23251, so that it can only rotate with the toothed ring 2325. The rotation of the toothed ring 2325 will also drive the cutter 2324 The gear ring 2325 rotates around the outer wall of the lamp tube for cutting. The rotation of the gear ring 2325 will apply pressure to the three-way cutter 2324 through the connecting bolt. The pressure will continuously apply pressure to the lamp tube through the cutter 2324 until the end of the lamp tube is cut off. The cut end will fall into the collection chamber 11 through the feed trough 12. After the end of the lamp tube is cut off, the exhaust mechanism absorbs the toxic gas inside the lamp tube through the exhaust hole 211. At the same time, the driving motor 2327 drives the gear ring 2325 to rotate in the opposite direction. The gear ring 2325 rotates in the opposite direction, thereby driving the blade part of the cutter 2324 to be retracted into the inside of the second installation groove 2323.

[0052] After the exhaust mechanism absorbs the toxic gas through the exhaust hole 211, the screw drive assembly 222 of the powder cleaning chamber 22 drives the motor assembly 223 and the powder cleaning assembly 224 to move toward the lamp tube, and the cleaning head 2244 will first enter the interior of the lamp tube. After the cleaning head 2244 enters the lamp tube, the extrusion plate 2249 will collide with the inner wall of the lamp tube first, and the lamp tube will press the extrusion plate 2249 into the top groove 22445. While the extrusion plate 2249 is squeezed into the top groove 22445, one end of the extrusion plate 2249 will squeeze the extrusion groove 22481 to move the docking block 2248 and the movable rod 2245. The movement of the movable rod 2245 will push the scraper 2247 to rise through the connecting rod 2246, so that the scraper 2247 fits the inner wall of the lamp tube, and then the motor assembly 223 pushes the drive rod 22 41 drives the cleaning head 2244 and the scraper 2247 to rotate. The rotation of the scraper 2247 will scrape off the fluorescent powder on the inner wall of the lamp tube. The screw drive assembly 222 drives the powder cleaning assembly 224 to move toward the powder cleaning chamber 21. The sleeve 2243 is used to push the scraped fluorescent powder while moving. If the sleeve 2243 is stuck by the fluorescent powder and cannot move, after the scraper 2247 is inserted into the powder cleaning chamber 21 and separated from the light, the spring 2242 will be compressed to the extreme and rebound to push the fluorescent powder lamp out of the lamp tube. At the same time, the pushing of the spring 2242 will drive the sleeve 2243 to hit the cleaning head 2244, thereby also playing the role of cleaning the cleaning head 2244. The scraped fluorescent powder enters the collection chamber 11 through the feed trough 12 below the powder cleaning chamber 21.

[0053] After the scraper 2247 finishes scraping the inner wall of the lamp tube and detaches from the lamp tube, the spring 22443 will push the movable rod 2245 and the docking block 2248 to reset, so that the scraper 2247 is retracted into the knife groove 22444, and the extrusion plate 2249 extends out of the top groove 22445. After the extrusion plate 2249 is extended, it will be stuck on the wall of the lamp tube. As the screw drive assembly 222 pulls the motor assembly 223 and the powder cleaning assembly 224 to reset, the lamp tube will be pulled into the powder cleaning chamber 22 together, and then the knocking assembly 221 will fall to break the lamp tube, and the broken glass fragments will enter the collection chamber 11 through the feed trough 12 below the powder cleaning chamber 22.

[0054] In summary, compared with the prior art, the embodiments of the present invention have the following advantages:

[0055] 1. Thanks to the well-designed powder cleaning mechanism 2, especially the scraper 2247 in the powder cleaning component 224, it can fit closely to the inner wall of the lamp tube and efficiently scrape off the attached fluorescent powder. The elastic force of the spring 1 2242 and the spring 2 22443 not only ensures the smoothness of the scraping process, but also can smoothly push out the fluorescent powder after scraping, significantly improving the recovery efficiency of the fluorescent powder and reducing resource waste.

[0056] Second, by integrating multiple automated components, such as the telescopic rod 13, the motor assembly 223, the screw drive assembly 222 and the drive motor 2327, these components work together to achieve a fully automated process from lamp tube cutting, phosphor removal to glass fragment processing. With the help of an intelligent control system, the operating status of each component can be accurately controlled to ensure that the recycling operation is both stable and efficient.

[0057] 3. The design of the sealing cutting assembly 23, especially the elastic sealing function of the rubber sheet 2313, effectively prevents the leakage of toxic gases during the cutting process. At the same time, the exhaust mechanism promptly extracts the toxic gases inside the lamp tube through the exhaust hole 211, further ensuring the safety of the operating environment.

[0058] Fourth, the precise meshing of the toothed ring 2325 and the gear 2326 of the cutting ring 232 ensures accurate cutting of the lamp tube. The scraper 2247 in the powder cleaning assembly 224 can flexibly adapt to different shapes of the inner wall of the lamp tube through the hinge design of the connecting rod 2246 and the movable rod 2245 to achieve thorough removal of the fluorescent powder. In addition, the setting of the sleeve 2243 not only helps to collect the fluorescent powder, but also can push the scraped fluorescent powder during the movement to prevent the occurrence of blockage.

[0059] 5. The overall structure of the present invention is compactly designed, and the connections between the components are tight and reasonable, ensuring the stability and durability of the equipment. At the same time, each component is easy to disassemble and replace, which is convenient for daily maintenance and reduces the maintenance cost of the equipment.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
