A fixed cylinder 2 is fixedly connected to the base 1. The conveying mechanism includes a rotating column 3 rotatably connected to the inner wall of the fixed cylinder 2. Eight groups of conveying troughs 4 are evenly opened in the rotating column 3, which are used to drive the rotating column 3 to rotate and switch the position of the conveying trough 4 to realize the recovery and conveying operation of the electrode metal. There are two groups of filtering mechanisms and both are installed on the base 1. They are used to discharge the undissolved electrode raw materials first during the switching of the conveying trough 4, and then filter and output the dissolved metal after sedimentation. The driving mechanism is installed on the base 1, and is used to link the filtering mechanism to output solids and circulate liquids during the switching of the conveying trough 4.

[0033] See also Figures 1-9 , a recycling method for a metal recycling device for LED metal electrodes shown in the figure includes the following steps:

[0043] The pumping part includes a driving plate 21 that is slidably connected to the inner wall of the connecting pipe 20.

The output end of the driving motor 24 is coaxially fixedly connected with a driving shaft 25. The driving shaft 25 passes through the bottom plate 6 and the top plate 5, and is rotatably connected to the bottom plate 6 and the top plate 5. The driving shaft 25 is coaxially fixedly connected to the rotating column 3 and the rotating disk 11. A swing rod 26 is rotatably connected to the base 1.

[0046] In this embodiment, by briefly describing the state of one group of conveying troughs 4 during one rotation, the conveying processing states of the materials in the remaining seven groups of conveying troughs 4 will all perform the same operation in sequence during the process of the rotating column 3 rotating one rotation. The LED metal electrode with recycling is loaded into the hopper 8, the sedimentation liquid is loaded into the first input tank 9, and the dissolving liquid is loaded into the second input tank 10. The driving motor 24 drives the driving shaft 25 to rotate, so that the rotating column 3 and the rotating disk 11 rotate synchronously. The description starts from when the conveying trough 4 rotates to the bottom of the second input tank 10. At this time, the liquid at the bottom of the second input tank 10 flows into the corresponding second threaded hole 13, then the rotating column 3 drives the conveying trough 4 to rotate 45°, and the first threaded hole 12 can be rotated to the bottom of the hopper 8, and the set amount of LED metal electrode raw material falls into the threaded tube 34 in the first threaded hole 12, and then the conveying trough 4 is rotated 45°. At this time, the upper end of the conveying trough 4 is connected to a group of conveying ports 14, and the raw materials in the first threaded hole 12 and the second threaded hole 13 above fall into the liquid in the conveying trough 4 through the conveying ports 14. The liquid is vibrated by the ultrasonic oscillator 36 at the bottom to improve the contact reaction efficiency between the dissolving liquid and the surface of the raw material, and the metal required on the surface of the LED metal electrode is dissolved.

[0047] After that, the conveying trough 4 is driven to rotate 45 degrees. At this time, the bottom of the conveying trough 4 is connected to one of the first pipes 15. In the process of the driving motor 24 driving the driving shaft 25 to rotate, the driving wheel 30 drives the driven wheel 31 to rotate through the transmission belt 32. The driven wheel 31 drives the driving disk 29 to rotate, so that the connecting rod 33 pushes and pulls the swing rod 26 back and forth. The swing rod 26 rotates around the central axis, so that the driving grooves 27 at both ends drive the driving blocks 28 to move. The driving block 28 drives the driving rod 23 and the driving plate 21 to slide back and forth in the connecting pipe 20. When the driving plate 2 When the driving plate 21 slides toward the first pipe 15, the liquid in the connecting pipe 20 flows into the connecting pipe 20 near the second pipe 16 through the second one-way valve 22. When the driving plate 21 slides toward the second pipe 16, the driving plate 21 pushes the liquid in the connecting pipe 20 into the second pipe 16 and delivers it to the upper connected delivery trough 4 through the first one-way valve 19. At the same time, the liquid in the first pipe 15 and the delivery trough 4 above the first pipe 15 is delivered to the lower connecting pipe 20 through the filter 18 and the first one-way valve 19 for storage. At this time, only undissolved LED raw materials remain in the delivery trough 4.

[0048] As the conveying trough 4 continues to rotate 45°, the undissolved raw materials inside are rotated into the first group of output pipes 17 and discharged downward. At this time, the second threaded hole 13 above the conveying trough 4 is connected to the bottom end of the first input tank 9, and a set amount of sedimentation liquid is input into the second threaded hole 13 for storage. Then the conveying trough 4 is rotated 45° again to be connected to the top end of the second pipe 16. At the same time, the top end of the conveying trough 4 is connected to the bottom end of another group of conveying ports 14. Under the push of the driving plate 21, the dissolved liquid and dissolved metal in the other group and the first pipe 15 are conveyed into the conveying trough 4. At the same time, the sedimentation liquid in the second threaded hole 13 will also fall into the conveying trough 4 through the conveying port 14, mix with the dissolved metal, and cause the metal to be precipitated.

[0049] Then, the conveying trough 4 is controlled to rotate 45 degrees so that its bottom end is connected to another set of first pipes 15. The liquid in the conveying trough 4 is pumped into the conveying trough 4 on the upper side of the second pipe 16 through the reciprocating movement of the driving plate 21. Only the required metal after precipitation remains in the conveying trough 4. The conveying trough 4 is controlled to rotate 45 degrees so that its bottom end is connected to another set of output pipes 17. The metal precipitation in the conveying trough 4 is output through the output pipe 17. At this time, the second threaded hole 13 on the upper side of the conveying trough 4 is connected to the second input tank 10 again for quantitative input of the dissolved liquid. The conveying trough 4 is controlled to rotate 45 degrees so that the bottom end of the conveying trough 4 is connected to the output pipe 17. The bottom end is connected with another group of second pipes 16, so that the liquid pumped by the first pipe 15 on the other side can be input into the conveying trough 4 through the connecting pipe 20 for recycling. At the same time, the first threaded hole 12 at the upper end of the conveying trough 4 is connected with the bottom end of the feed hopper 8 again for the input of raw materials. As the conveying trough 4 rotates 45 degrees again and is connected with the bottom end of the conveying port 14, the raw materials in the first threaded hole 12 and the second threaded hole 13 above can be dropped into the liquid in the conveying trough 4 through the conveying port 14 for mixing reaction. This reciprocating operation is achieved through the switching operation of eight groups of conveying troughs 4 to achieve the purpose of continuous automatic operation, and the operation is more convenient and efficient.

[0050] It is worth noting that: according to the amount of raw materials required to be added each time, a threaded tube 34 with a suitable inner diameter is selected to be screwed into the first threaded hole 12 and the second threaded hole 13, so that the raw materials can be quantitatively input into the first threaded hole 12 and the second threaded hole 13 each time during the rotation of the rotating disk 11, and then transported to the conveying trough 4 for mixing. Since the radius of the driving wheel 30 is much larger than the radius of the driven wheel 31, the driving shaft 25 can drive the driving disk 29 to rotate 360° when driving the rotating column 3 to rotate 45°, so that the driving plate 21 performs a complete reciprocating movement, completing the sequential pumping and filtration operation of the liquid.

[0051] Among them, in order to ensure the air pressure balance in the conveying trough 4 during the reaction process and the liquid pumping process, each time the conveying trough 4 rotates 45°, the exhaust holes 35 on the top plate 5, the rotating disk 11 and the fixed plate 7 will be connected for a period of time. At the same time, in order to prevent a certain amount of liquid from being taken away during the precipitation discharge process, which causes the liquid amount in the conveying trough 4 to continue to decrease, an external input pipe can be connected to the upper end position of a group of exhaust holes 35 to supplement the liquid and ensure the balance and sufficiency of the liquid amount inside the conveying trough 4, so that the dissolved liquid and the raw materials can be fully mixed and contacted inside for reaction.

[0052] When the delivery amounts of the dissolving liquid and the sedimentation liquid are different, another set of second threaded holes 13 can be provided so that the two sets of second threaded holes 13 are connected to the bottom ends of the first input tank 9 and the second input tank 10 respectively as the rotating disk 11 rotates, thereby completing the separate input operations of the liquid raw materials. According to the different types of metals to be dissolved, the selection of the dissolving liquid and the sedimentation liquid is also different, which can be flexibly controlled and adjusted.
