[0024] Please see Figures 1-5 As shown, this utility model is a wet impurity removal device, including a reaction tank 10, which is placed on the ground by a support column, and a dust feed pipe 11 is connected through the top of the reaction tank 10; a stirring assembly, which is set inside the cavity of the reaction tank 10, and includes a main shaft 16, a stirring rod 18 and a scraper 19; a material injection and circulation assembly, which includes a liquid feed pipe 12, a hollow pipe 20 and a liquid outlet pipe 21, with the hollow pipe 20 movably passing through the main shaft 16, and the liquid outlet pipe 21 being connected through the hollow pipe 20, with multiple sets of nozzles provided on the outer wall of the liquid outlet pipe 21, and a material suction unit provided above the hollow pipe 20, which includes a cylindrical cylinder 29 and a second cylinder 30; and a rotary drive assembly, which includes a first gear 15 and a second gear 25, with the first gear 15 meshing with the second gear 25.

[0025] By connecting the top of the reaction tank 10 to the dust feed pipe 11, zinc oxide dust enters the reaction tank 10 through the dust feed pipe 11. Acidic liquid enters the reaction tank 10 through the liquid feed pipe 12 and the hollow pipe 20. By setting up a stirring assembly, the powder and liquid can be stirred to accelerate the acid leaching process. In the impurity removal stage, the precipitant is added to the hollow pipe 20 through the liquid feed pipe 12 and sprayed out through the nozzle. The precipitant and solution are fully mixed and react rapidly. By setting up a material circulation assembly, the liquid in the reaction tank 10 can be drawn into the outlet pipe 21 through the one-way valve 22 and then sprayed out, so that the liquid is circulated, which helps the precipitant and solution to mix fully, accelerates the reaction speed, and improves production efficiency. After the reaction is completed, the height of the main shaft 16 is lowered, and the scraper 19 contacts the bottom of the reaction tank 10 to scrape the precipitate, making the discharge more efficient.

[0026] Among them, such as Figures 1-2 As shown, a support frame 23 is fixedly installed at the top of the reaction vessel 10, and a drive motor 13 is fixedly installed on one side of the support frame 23. The output shaft of the drive motor 13 is fixedly connected to a rotating rod 14, and the rotating rod 14 is fixedly inserted through the first gear 15.

[0027] Specifically, by fixing a support frame 23 to the top of the reaction vessel 10, the drive motor 13 is secured. When the drive motor 13 is working, it drives the rotating rod 14 to rotate. The rotating rod 14 is fixedly inserted through the first gear 15, thereby driving the first gear 15 to rotate.

[0028] The main shaft 16 extends through the top of the reaction vessel 10. There are multiple sets of stirring rods 18, which are fixedly installed on the outer wall of the main shaft 16. The multiple sets of stirring rods 18 are arranged in a ring array. The scraper 19 is fixedly installed at the bottom of the main shaft 16, and the bottom of the scraper 19 is arc-shaped.

[0031] Specifically, by setting the liquid feed pipe 12 to be connected to the hollow pipe 20, and setting the solenoid valve 17 on the outer wall of the liquid feed pipe 12, the liquid material is controlled to enter the hollow pipe 20.

[0032] The diameter of the outlet pipe 21 is smaller than that of the hollow pipe 20, and a one-way valve 22 is installed through the bottom of the outlet pipe 21.

[0033] Specifically, by setting the diameter of the outlet pipe 21 to be smaller than that of the hollow pipe 20, and installing a one-way valve 22 through the bottom of the outlet pipe 21, when the material injection circulation component is working, the liquid enters the cavity of the outlet pipe 21 through the one-way valve 22, and when the second cylinder 30 pushes the piston downward, the liquid is sprayed out through the nozzle.

[0034] Among them, such as Figure 5 As shown, the second gear 25 is fixedly passed through the top of the outer wall of the main shaft 16. The third gear 24 is also fixedly passed through the main shaft 16. The third gear 24 is located below the second gear 25. The third gear 24 and the second gear 25 are the same size and shape. The lifting plate 26 is movably installed at the top of the main shaft 16 through the bearing. The guide rod 27 is fixedly installed in the cavity of the support frame 23. The guide rod 27 movably passes through the lifting plate 26.

[0035] By setting the main shaft 16 to be fixedly connected through the second gear 25 and the third gear 24, the second gear 25 is movably meshed with the first gear 15. The rotation of the first gear 15 drives the second gear 25 and the main shaft 16 to rotate synchronously. When the first cylinder 28 is working, it drives the lifting plate 26 and the main shaft 16 to descend as a whole. At this time, the first gear 15 is movably meshed with the third gear 24. The rotation of the first gear 15 drives the third gear 24 and the main shaft 16 to rotate synchronously. The guide rod 27 is set to movably pass through the lifting plate 26 to limit and guide the lifting of the lifting plate 26.

[0036] A first cylinder 28 is fixedly installed at the top of the support frame 23. The telescopic end of the first cylinder 28 moves through the support frame 23 and is fixedly connected to the lifting plate 26.

A piston is movablely engaged in the cavity of the cylindrical cylinder 29. A second cylinder 30 is fixedly installed at the top of the support frame 23. The telescopic end of the second cylinder 30 moves through the support frame 23 and is fixedly connected to the piston in the cavity of the cylindrical cylinder 29.

[0037] Specifically, a second cylinder 30 is fixed to the top of the support frame 23. The telescopic end of the second cylinder 30 extends through the support frame 23 and is fixedly connected to the piston inside the cylindrical cylinder 29. When the second cylinder 30 is working, it drives the piston to move upward. At this time, the liquid in the reaction tank 10 enters the outlet pipe 21 through the one-way valve 22. When the telescopic end of the second cylinder 30 pushes the piston downward, the liquid in the outlet pipe 21 is sprayed out, so that the liquid in the reaction tank 10 is circulated and sprayed, which accelerates the reaction efficiency.

[0038] The specific working principle of this wet impurity removal device is as follows: Zinc oxide dust enters the reaction tank 10 through the dust feed pipe 11, and acidic liquid enters the reaction tank 10 through the liquid feed pipe 12 and the hollow pipe 20. By setting a stirring component, the powder and liquid can be stirred to accelerate the acid leaching process. In the impurity removal stage, the precipitant is added into the hollow pipe 20 through the liquid feed pipe 12 and sprayed out through the nozzle. The precipitant and solution are fully mixed and react rapidly. By setting a material circulation component, the liquid in the reaction tank 10 can be drawn into the outlet pipe 21 through the one-way valve 22 and then sprayed out, so that the liquid circulates, which helps the precipitant and solution to mix fully, accelerates the reaction speed, and improves production efficiency. After the reaction is completed, the height of the main shaft 16 is lowered, and the scraper 19 contacts the bottom of the reaction tank 10 to scrape the precipitate, making the discharge more efficient.
