[0001] The present invention relates to the technical field of copper powder production, and specifically relates to a device for wet preparation of copper powder with low apparent density. Background Art

[0002] Copper powder is one of the powders for metal additive manufacturing. When producing copper powder, wet preparation is usually adopted. Wet preparation of copper powder is a method of producing copper powder in a liquid phase environment. It mainly uses chemical reactions or physical processes to generate copper particles in a solution, and then obtains copper powder through a series of subsequent processing steps. Wet preparation can select appropriate reducing agents and reaction conditions, and can control the particle size and morphology of copper powder, thereby reducing the apparent density. After the copper particles are prepared by wet method, they need to be separated from the liquid, and filtration is mostly used for separation. However, the installation of the filter plate in the existing wet preparation device is rather troublesome, and after the filter plate is used, it needs to be disassembled and cleaned to ensure its filtering effect. Since it cannot be conveniently installed and disassembled, a lot of time is often spent on the installation and disassembly of the filter plate, which is very inconvenient.

[0035] As Figure 1 , Figure 2 and Figure 8 shown, the movable filtering mechanism is a movable filter plate 3. Connecting lock holes 31 are symmetrically arranged on both sides of the movable filter plate 3. When the movable filter plate 3 is installed on the carrying strip plate 2, it is located between the carrying strip plate 2 and the fitting closing plate 4. And both ends of the movable filter plate 3 are in contact with the carrying strip plate 2 and the fitting closing plate 4 respectively.

[0038] As Figure 9 shown, a movable connecting rod 64 is inserted into the movable carrier hole 61. The upper end of the movable connecting rod 64 is fixedly provided with a bearing top plate 65, a cooperating connecting plate 66 is fixedly arranged on the bearing top plate 65, the lower end of the cooperating connecting plate 66 is hinged to the cooperating pull rod 53. One end of the movable carrier block 6 is fixedly provided with a supporting end plate 67, a loading plate strip 68 is fixedly arranged on the supporting end plate 67, a connecting lock post 69 is fixedly arranged on the loading plate strip 68, and the connecting lock post 69 is inserted into the bearing jack 22.

[0039] When the connecting lock post 69 realizes the fixed connection between the carrying strip plate 2 and the movable filter plate 3, it is inserted into the connecting lock hole 31.

[0040] As Figure 2 , Figure 4 and Figure 10 shown, the movable discharging assembly includes a channel closing plate 7, a driving strip 8 and a receiving bucket 9. The channel closing plate 7 is arranged below the discharging channel 18 and the channel closing plate 7 is in contact with the sealing ring gasket 19. A conical sliding table 71 is fixedly arranged on the channel closing plate 7, a blanking channel 72 is formed in the channel closing plate 7, the blanking channel 72 is around the conical sliding table 71, and mounting plate strips 73 are symmetrically and fixedly arranged on both sides of the channel closing plate 7. The mounting plate strips 73 are inserted into the carrying channels 16. Before the channel closing plate 7 moves downward, it blocks the discharging channel 18. At this time, the conical sliding table 71 is inserted into the discharging channel 18.

[0041] As Figure 2 , Figure 4 and Figure 10As shown in the figure, an installation through-hole 74 is provided at the upper end of the installation strip 73, and a mating carrier plate 75 is fixedly arranged. A plugging through-hole 76 is provided on the mating carrier plate 75. A driving strip 8 is installed on the installation strip 73. An installation plug rod 81 is fixedly arranged on the driving strip 8. The installation plug rod 81 is plugged in the installation through-hole 74, and a mating spring 82 is sleeved on the installation plug rod 81. The two ends of the mating spring 82 are respectively fixed on the installation strip 73 and the driving strip 8. A mating push rod 83 is hinged on the driving strip 8. The other end of the mating push rod 83 is hinged with a positioning carrier block 84. A positioning mating rod 85 is fixedly arranged on the positioning carrier block 84.

The receiving barrel 9 is plugged in the alignment groove 101, and the receiving barrel 9 is located directly below the discharge channel 18.

[0042] When preparing copper powder, the reaction solution is added to the space of the preparation box 1 between the fitting closing plate 4 and the support connecting frame 14. After the reaction is complete, the electric telescopic rod 13 is started at this time, which will drive the carrying strip 2 to move in the direction of the support connecting frame 14, and then can drive the movable filter plate 3 and the fitting closing plate 4 to move synchronously. During the movement, as the distance between the fitting closing plate 4 and the support connecting frame 14 becomes smaller, under the action of the upper driving push rod 42, the fitting closing plate 4 will be pushed upward, and then the fitting closing plate 4 will reduce the blockage of the filter holes on the movable filter plate 3. In this way, the solution will pass through the movable filter plate 3 and be discharged from the drain pipe 11. At the same time, as the movable filter plate 3 moves, it will also compress the space accumulated by the copper particles, and finally concentrate the copper particles on the upper side of the discharge channel 18. As the fitting closing plate 4 moves upward, the upper pushing and cooperating rod 45 will contact the rotating driving plate 52. Then, under the action of the upper pushing and cooperating rod 45, the rotating driving plate 52 will be pushed to rotate upward, thereby driving the cooperating pull rod 53 to rotate downward. As the cooperating pull rod 53 rotates downward, it will drive the movable connecting rod 64 to move downward. At the same time, under the action of the cooperating pull rod 53, the movable carrier block 6 will be driven to move. As the movable carrier block 6 moves, the connecting lock post 69 will be driven to move, so that the connecting lock post 69 is no longer inserted into the connecting lock hole 31. In this way, the movable filter plate 3 will lose its fixed connection with the carrying strip 2, which is convenient to disassemble and clean. The operation is simple, convenient and fast, without complicated installation and disassembly operations. In addition, as the carrying strip 2 moves, the cooperating strip 25 will contact the driving strip 8. In this way, under the action of the cooperating strip 25, the driving strip 8 will be pushed to move in the direction of the mounting strip 73. As the driving strip 8 moves, under the action of the cooperating push rod 83, the positioning carrier block 84 will be driven to move, so that the positioning cooperating rod 85 on the positioning carrier block 84 exits the cooperating connecting hole 17. In this way, the channel closing plate 7 can be in an unlocked state, so that under the action of the gravity of the copper particles and the channel closing plate 7 itself, it will move downward to open the discharge channel 18, and the copper particles can automatically fall and be discharged into the receiving bucket 9 to realize automatic discharging and collection. As the channel closing plate 7 moves downward, at this time, the positioning cooperating rod 85 abuts against the carrying strip block 15, and the cooperating spring 82 is always in a compressed state. After the movable filter plate 3 is cleaned, it is inserted again between the carrying strip 2 and the fitting closing plate 4, and then the electric telescopic rod 13 is started to drive the carrying strip 2 to reset, which can realize the automatic fixed connection between the movable filter plate 3 and the carrying strip 2. The channel closing plate 7 is pushed upward to close the discharge channel 18 again. And when the positioning cooperating rod 85 is aligned with the cooperating connecting hole 17, under the action of the cooperating spring 82, the driving strip 8 is driven to reset, so that the positioning cooperating rod 85 is inserted into the cooperating connecting hole 17 again to realize the fixation of the channel closing plate 7.
