[0002] In the production of silver powder, raw materials often contain various impurities, such as metal oxides, unreacted metal particles, and non-metallic impurities. These impurities severely affect the purity and quality of silver powder, thus impacting its application performance in many fields, including electronics and chemicals.

Therefore, this paper presents an impurity separation device for silver powder production. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1, referring to Figure 1-5 An impurity separation device for silver powder production includes a housing 1. Two end plates 3 are symmetrically fixed to the top of the housing 1. A feeding hopper 4 is fixed to the top between the two end plates 3. An inclined screen 5 is fixed below the feeding hopper 4. An electromagnetic vibrator 8 is installed on the outer wall of the high end of the screen 5. A magnetic separation component is installed between the two end plates 3 and below the low end of the screen 5. A centrifugal separation component is installed inside the housing 1 and below the magnetic separation component. A rinsing component is installed inside the housing 1 and below the centrifugal separation component. A drain outlet 12 is provided in the middle of the bottom end of the housing 1. A discharge outlet 11 is provided on one side of the housing 1. A filter plate 15 is fixed inclined above the discharge outlet 11. Support legs 9 are fixed at the four corners of the lower end face of the housing 1.

[0023] The magnetic separation assembly includes a magnetic roller 6 that is rotatably mounted between two end plates 3 via bearings. An electromagnet is installed inside the magnetic roller 6. A first servo motor 2 is fixed to one side of one end plate 3, and the output end of the first servo motor 2 is connected to one end of the magnetic roller 6.

[0024] A guide chute 13 is fixed between the two end plates 3 and below one side of the magnetic roller 6. The high end of the guide chute 13 slides in contact with the outer wall of the magnetic roller 6.

[0025] The centrifugal separation assembly includes a support rod 18 fixed inside the housing 1. A second servo motor 16 is installed at the lower middle part of the support rod 18. The output end of the second servo motor 16 extends to the top of the support rod 18 and is equipped with a separation cylinder 7. The separation cylinder 7 is provided with uniformly distributed filter holes.

[0026] Silver powder containing impurities falls from the hopper 4 into the screen 5. The screen 5 vibrates due to the electromagnetic vibrator 8, which increases the screening speed of the material. Fine impurity powder falls onto the guide chute 13, and then the material falls along the screen 5 onto the magnetic roller 6. Magnetic impurities are attracted to the surface of the magnetic roller 6. The magnetic roller 6 is driven to rotate by the first servo motor 2, so that the magnetic impurities accumulate at the high end of the guide chute 13. The silver powder falls from the magnetic roller 6 into the separation cylinder 7. The separation cylinder 7 is driven to rotate at high speed by the second servo motor 16, so that the silver powder is thrown out from the filter holes of the separation cylinder 7. Large particles of impurities remain in the separation cylinder 7. The thrown-out silver powder falls along the collection hopper 14 onto the filter plate 15.

[0027] After separation, the magnetic impurities accumulated at the guide chute 13 are cleaned off. As the magnetic roller 6 rotates, the remaining magnetic impurities are scraped off and collected at the high end of the guide chute 13. Then, the electromagnet inside the magnetic roller 6 is de-energized, and the remaining magnetic impurities are cleaned off.

[0028] Example 2 is an optimization based on Example 1, specifically:

[0029] The rinsing assembly includes a collection hopper 14 fixed to the inner wall of the housing 1 and located below the separation cylinder 7. A water pipe 10 is fixed to the bottom outer wall of the collection hopper 14. Spray heads 17 are installed at equal intervals on the water pipe 10. One end of the water pipe 10 extends to the outer wall of the housing 1 and is equipped with a solenoid valve 19. One end of the solenoid valve 19 is connected to a water supply pipe. The high end of the filter plate 15 is located above the bottom end of the collection hopper 14.

[0030] By opening the solenoid valve 19, water is sprayed from the spray head 17 to rinse the silver powder on the filter plate 15, further removing tiny impurities. The filtered water is discharged from the drain outlet 12, and the pure silver powder is collected from the discharge outlet 11.

[0031] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
