[0013] The beneficial effects of the present utility model are as follows:

Specific Embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] Refer to Figures 1 - 3, a device for removing impurities from copper powder of waste printed circuit boards, comprising a housing 1. At the top of one side of the housing 1, a water inlet pipe 2 is hermetically inserted. Below the water inlet pipe 2 on this side of the housing 1, a first drain pipe 3 and a second drain pipe 4 are hermetically inserted. Valves are provided on the water inlet pipe 2, the first drain pipe 3 and the second drain pipe 4. A partition 5 is rotatably connected between the inner walls on both sides of the housing 1. Water is injected into the housing 1 from the water inlet pipe 2, and the water level should exceed the partition 5 to precipitate the copper powder, so that the copper powder precipitates at the bottom of the housing 1, and small particles of the base material of the waste circuit board float on the water surface, thereby removing impurities from the copper powder. The first drain pipe 3 and the second drain pipe 4 are respectively located above and below the partition 5. A first motor 9 is fixed to the outer wall of one side of the housing 1 by bolts. The output end of the first motor 9 is fixedly connected to one end of the partition 5. Driven by the first motor 9, the partition 5 rotates, so that the partition 5 is rotated to a vertical state, so that the copper powder and small particle impurities fall to the bottom of the housing 1.

[0023] A top cover 6 is rotatably connected to the top of the housing 1. A handle 7 is fixed to the outer wall of the top of the top cover 6 by bolts. Pull the handle 7 to cover the top cover 6 on the top of the housing 1. A screen 8 is clamped at the top end inside the housing 1. Large particle impurities in the copper powder are filtered out through the screen 8. Sealing gaskets 10 are bonded to the inner walls on both sides of the housing 1. Both sides of the partition 5 are in contact with the sealing gaskets 10. The sealing gaskets 10 are used to seal between the partition 5 and the inner walls on both sides of the housing 1. A first stirring shaft 12 and a second stirring shaft 13 are rotatably inserted at the bottom between the inner walls on both sides of the housing 1. One end between the first stirring shaft 12 and the second stirring shaft 13 is connected by a synchronous belt through pulley transmission. A plurality of stirring rods 14 are welded to the outer walls of the first stirring shaft 12 and the second stirring shaft 13. A second motor 11 is fixed to the outer wall of one side of the housing 1 by bolts. The output end of the second motor 11 is fixedly connected to one end of the first stirring shaft 12. Driven by the second motor 11 and the transmission of the synchronous belt, the first stirring shaft 12 and the second stirring shaft 13 rotate, so as to stir the water and the copper powder, so that small particles of the base material of the waste circuit board completely float on the water surface.

[0024] Working principle: When in use, first, pull the handle 7 to open the top cover 6. Then, put copper powder into the housing 1. Next, the copper powder falls on the sieve mesh 8, and the large particle impurities in the copper powder are filtered out through the sieve mesh 8. The copper powder and small particle impurities fall on the partition plate 5. Then, driven by the first motor 9, the partition plate 5 rotates, so that the partition plate 5 is rotated to the vertical state. Next, the copper powder and small particle impurities fall to the bottom of the housing 1. Then, inject water into the housing 1 from the water inlet pipe 2, and the water level should exceed the partition plate 5 to precipitate the copper powder, so that the copper powder precipitates at the bottom of the housing 1, and the small particles of waste printed circuit board substrate material float on the water surface. At the same time, driven by the second motor 11 and the transmission of the synchronous belt, the first stirring shaft 12 and the second stirring shaft 13 rotate to stir the water and copper powder, so that the small particles of waste printed circuit board substrate material completely float on the water surface. After precipitation for a period of time, driven by the first motor 9, the partition plate 5 is rotated to the horizontal state, so that the housing 1 is divided into two independent parts from the partition plate 5. Then, the copper powder and the small particles of waste printed circuit board substrate material are discharged from the first drain pipe 3 and the second drain pipe 4.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
