The driving element 41 is fixedly connected to the top of the first grinding element 22, and there are three driven elements 42, which are movably connected to the bottom of the three coarse grinding chambers 31 respectively. The first grinding element 22 drives the coarse grinding chambers 31 to rotate. The rotating active member 41 provides the driven member 42 with a force in both rotational and circumferential directions. The function of the first conveying mechanism 5 is to convey waste material into the coarse grinding chamber 31. There are three feed members 54, which are respectively opened on the surface of the connecting member 33 at the top of the three coarse grinding chambers 31. When the feed member 54 is connected to the first connecting member 53, the top of the first separating member 52 is connected to the inside of the coarse grinding chamber 31, so that the waste material can fall into the inside of the coarse grinding chamber 31 through the first connecting member 53 and the feed member 54. The function of the second conveying mechanism 6 is to convey the coarse grinding waste material inside the coarse grinding chamber 31 to the inside of the fine grinding chamber 21. There are three discharge ports 62, which are respectively opened on the surface of the three driven members 42. When the driven member 42 drives the discharge port 62 to rotate to the top of the second connecting member 63, the coarse grinding chamber 31 is connected to the inside of the fine grinding chamber 21, so that the waste material inside the coarse grinding chamber 31 falls into the inside of the fine grinding chamber 21.

[0036] The bottom of the grinding box 1 is connected to a fine grinding chamber 21, a driving component 23, and a discharge component 24. The fine grinding chamber 21 provides a space for fine grinding of phosphor powder. The driving component 23 is used to drive the first grinding component 22 to rotate and can be an electric motor, a motor, or an internal combustion engine, preferably an electric motor. The discharge component 24 is used for discharging material.

[0037] The fine grinding chamber 21 is formed by the second separator 61. The first grinding element 22 is rotatably installed inside the fine grinding chamber 21. The driving element 23 is installed on the outer surface of the bottom of the grinding box 1.

The drive 23 drives the first grinding piece 22 to rotate the drive 41. The driven 42 meshes with the drive 41 and the meshing piece 43. It is connected to the coarse grinding chamber 31 and the connecting piece 33. The coarse grinding chamber 31 rotates circumferentially while the second grinding piece 32 rotates. When the feed piece 54 rotates to the bottom of the first connecting piece 53, the waste falls into the coarse grinding chamber 31 through the first connecting piece 53 and the feed piece 54. It is stored and ground by the rotation of the second grinding piece 32. When the driven 42 rotates to the top of the second connecting piece 63, the waste in the coarse grinding chamber 31 falls into the fine grinding chamber 21 through the discharge port 62 and the second connecting piece 63. Finally, it is finely ground by the first grinding piece 22 and discharged from the discharge piece 24.

The first grinding element 22 rotates to perform fine grinding. This device can coarsely grind larger phosphors and then perform fine grinding, thereby improving the uniformity and quality of grinding.

[0048] Second Embodiment

[0049] Please refer to the following: Figure 3 Based on the phosphor recycling device provided in the first embodiment of this application, the second embodiment of this application proposes another phosphor recycling device. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0050] Specifically, the difference in the second embodiment of this application regarding the fluorescent powder recycling device is that the surface of the grinding box 1 of the fluorescent powder recycling device is provided with a sieving mechanism 7, which includes a sieving component 71, a vibrating component 72, an impact component 73, a first transmission component 74, and a second transmission component 75.

[0051] The screening component 71 can be a stainless steel screen, a galvanized iron wire screen, or a nylon screen, preferably a nylon screen. Both ends of the screening component 71 are movably embedded on the outside through the surface of the grinding box 1. The vibrating component 72 can be a rod with a spring or a sheet connected to its surface, preferably a spring. Both ends of the screening component 71 are slidably connected to the surface of the connecting rod and connected to the spring.

[0052] The vibrating element 72 and the striking element 73 cooperate to complete the vibration of the screening element 71, and the first transmission element 74 and the second transmission element 75 are connected to drive the striking element 73 to rotate.

[0053] The second transmission component 75 can be a pulley, gear, or bevel gear, preferably a pulley. The two first transmission components 74 are respectively fixedly connected to the top of the left and right pulleys. The two striking components 73 are respectively fixedly connected to the top of the two first transmission components 74 and connected to both ends of the screening component 71.

[0054] The working principle of the phosphor recycling and reuse device provided by this utility model is as follows:

[0055] When the waste material is poured into the grinding box 1, it first falls to the top of the screening component 71. The driving component 23 drives the first grinding component 22 to rotate. Through the impact component 73 and the first transmission component 74, the two impact components 73 are driven to rotate. The eccentric force of the two impact components 73 strikes the two ends of the screening component 71. The screening component 71 moves left and right and gives the vibrating component 72 a pushing and pulling force. The vibrating component 72 is subjected to force and extends and retracts back and forth, thereby driving the screening component 71 to vibrate. The waste material then falls through the screening component 71 to the top of the first separator 52.

[0056] Compared with related technologies, the phosphor recycling device provided by this utility model has the following advantages:

[0057] This utility model provides a phosphor recycling and reuse device. The first transmission component 74 and the second transmission component 75 drive the two striking components 73 to rotate and strike both ends of the screening component 71. At the same time, the vibration component 72 can vibrate the screening component 71 by extending and retracting, thereby screening out the impurities inside the phosphor, reducing the impurities inside the phosphor and improving the purity of the phosphor.
