[0025] A feed pipe 6 and an exhaust pipe 7 are provided on the top of the cleaning tank 1. The feed pipe 6 is used to introduce dust to be cleaned, solvent for cleaning, etc. into the cleaning tank 1. A feed valve 8 is provided on the feed pipe 6. The feed valve 8 is used to control the introduction of materials and the opening and closing of the feed pipe 6. An exhaust valve 9 is provided on the exhaust pipe 7. The exhaust valve 9 is used to control the exhaust of gas in the cleaning tank 1 and the opening and closing of the exhaust pipe 7. A solvent outlet pipe 10 and a nitrogen inlet pipe 11 are provided at the bottom of the cleaning tank 1. The solvent outlet pipe 10 is used to export the liquid solvent in the cleaning tank 1. The nitrogen inlet pipe 11 is connected to an external nitrogen bottle and is used to introduce nitrogen dioxide gas into the cleaning tank 1. The solvent outlet pipe 10 is provided with a solvent outlet. A valve 12 is provided, through which the discharge of the solvent in the cleaning tank 1 and the opening and closing of the solvent outlet pipe 10 are controlled. A nitrogen inlet valve 13 is provided on the nitrogen inlet, through which the introduction of nitrogen and the opening and closing of the nitrogen inlet pipe 11 are controlled. A filter barrel 2 is rotatably installed at the bottom of the cleaning tank 1, and the filter barrel 2 is driven to rotate by a spin-drying motor 3 installed at the bottom of the cleaning tank 1. Specifically, the output shaft of the spin-drying motor 3 extends into the cleaning tank 1 and is connected to the filter barrel 2, so that the spin-drying motor 3 can drive the filter barrel 2 to rotate. Micropores are provided on the side walls of the filter barrel 2. The side walls of the filter barrel 2 are made of ultrafine titanium powder sintering technology, and the pore size of the micropores is greater than 500 nanometers.

[0026] A stirring shaft 4 is rotatably installed at the top of the cleaning tank 1 . The lower end of the stirring shaft 4 extends downward into the filter barrel 2 and is provided with a stirring blade 14 . The stirring shaft 4 is driven to rotate by a stirring motor 5 installed at the top of the cleaning tank 1 .

[0027] The application process:

[0028] 1. Open the nitrogen inlet valve 13 and the exhaust valve 9, and introduce nitrogen into the cleaning tank 1 until the cleaning tank 1 is filled with nitrogen to form a protection to prevent the metal powder from being oxidized during the cleaning process; then close the nitrogen inlet valve 13 and the exhaust valve 9 to seal the cleaning tank 1;

[0029] 2. Open the feed valve 8, introduce the nano-powder to be cleaned and the cleaning solvent into the cleaning tank 1 through the feed pipe 6, and then close the feed valve 8 to seal the cleaning tank 1;

[0030] 3. Start the stirring motor 5, and drive the stirring shaft 4 and the stirring blades 14 on the stirring shaft 4 to rotate through the stirring motor 5, so that the impurities on the nano-scale micro-powder are fully dissolved in the solvent, and then stop the stirring motor 5; during stirring and cleaning, the spin-drying motor 3 can also be started at the same time to drive the filter barrel 2 to rotate in the opposite direction to the stirring shaft 4 to improve the stirring efficiency;

[0031] 4. Open the solvent outlet valve 12 and drain the solvent through the solvent outlet pipe 10. After a period of time, the liquid in the cleaning tank 1 has been basically discharged, and then start the stirring motor 5 and the drying motor 3, so that the filter barrel 2 and the stirring shaft 4 rotate synchronously, so that the solvent attached to the nano-scale micro-powders can be quickly thrown out through centrifugal action, so as to achieve rapid drying of the nano-scale micro-powders and effectively improve the rapid separation of the solvent and the nano-scale micro-powders.

[0032] In some specific embodiments, the feed pipe 6 is also connected to a pressurizing pipe 15, which is connected to an external nitrogen bottle. A pressurizing valve 16 is provided on the pressurizing pipe 15. When discharging the solvent, the pressurizing valve 16 can be opened to introduce high-pressure nitrogen from the top of the cleaning tank 1, thereby effectively increasing the discharge speed of the solvent and improving the working efficiency of the device.

[0033] In some specific embodiments, a heating chamber 17 is constructed in the side wall of the cleaning tank 1, and a high-pressure steam inlet pipe 18 and a high-pressure steam exhaust pipe 197 connected to the heating chamber 17 are provided on the outer side wall of the cleaning tank 1. The high-pressure steam inlet pipe 18 is arranged near the bottom of the cleaning tank 1, and the high-pressure steam exhaust pipe 197 is arranged near the top of the cleaning tank 1;

[0034] A high-pressure steam intake valve 20 is provided on the high-pressure steam intake pipe 18, and a high-pressure steam exhaust valve 219 is provided on the high-pressure steam exhaust pipe 197. After the nano-scale micropowder is spun dry, the high-pressure steam intake valve 20 and the high-pressure steam exhaust valve 219 are opened to introduce the high-pressure steam into the heating chamber 17, thereby increasing the internal temperature of the cleaning tank 1 to achieve heating and drying of the nano-scale micropowder in the tank body.

[0035] In some specific embodiments, an overflow valve 22 connected to the heating chamber 17 is also provided on the outer wall of the cleaning tank 1. When the pressure in the heating chamber 17 is too high, the steam in the heating chamber 17 can be discharged through the overflow valve 22, thereby effectively avoiding explosion accidents caused by excessive pressure in the heating chamber 17.

[0036] In some specific embodiments, the top of the filter barrel 2 is bent inward to form a step, which effectively prevents the nano-scale powder in the filter barrel 2 from being thrown out of the filter barrel 2 during the stirring or drying process, thereby improving the stability of the device operation.

[0037] The embodiments of the present application have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
