The first bevel gear 14 has a slot. The first bevel gear 14 is engaged with the engaging plate 13 through the slot. The engagement of the first bevel gear 14 with the engaging plate 13 allows the first rotating shaft 10 to move on the first bevel gear 14 and also rotate on its own axis. The end of the first rotating shaft 10 away from the second connecting rod 9 extends into the interior of the workbench 1. The interior of the workbench 1 is equipped with a stirring mechanism.

The rotating plate 6 passes through the first connecting rod 7 and is rotatably connected to the first connecting rod 7. The rotating plate 6 is adapted to the fixed rod 8. When filtering and cleaning iron powder particles, the motor 5 is started to drive the output shaft fixedly connected to its output end to rotate. The rotation of the output shaft drives the rotating plate 6 fixedly connected to it to rotate. The rotation of the rotating plate 6 drives the first connecting rod 7 fixedly connected to the fixed rod 8 to rotate through the fixed rod 8.

The stirring blade 22 can stir the iron powder particles and the cleaning liquid. When the first rotating shaft 10 moves up and down, it rotates, causing the first stirring rod 17, which is fixedly connected to it, to move up and down and rotate simultaneously. The rotation of the first stirring rod 17 can drive the second mounting shell 18, which is fixedly connected to it, to rotate. The rotation of the second mounting shell 18 drives the second stirring rod 21 to revolve, which in turn drives the stirring blade 22 fixedly connected to it to revolve.

Through multi-dimensional motion, the fluidity and shear force of the cleaning fluid are enhanced, the iron powder particles are fully dispersed, the cleaning dead angles are reduced, the product purity is higher, the cleaning efficiency is improved, and the subsequent processing costs are reduced. Reference Figure 1 and Figure 2The cleaning tank 2 has a feed inlet 3 at the top for filling the raw materials into the cleaning tank 2. The cleaning tank 2 has a corresponding filter box 26. A conveying assembly is provided between the cleaning tank 2 and the filter box 26. A filter plate 27 is fixedly connected inside the filter box 26. The filter plate 27 is used to filter the cleaning liquid. A vacuum pump 28 is provided on the side wall of the filter box 26. The vacuum pump 28 is below the filter plate 27 and forms a negative pressure below the filter plate 27, which allows the cleaning liquid to pass through the filter plate 27 and enter the bottom of the filter box 26. Iron powder remains on the surface of the filter plate 27 to form a filter cake. The filter cake is removed by opening the filter box 26. A drain pipe 29 is fixedly connected to the bottom of the filter box 26. The drain pipe 29 is connected to the filter box 26 and is used to discharge the cleaning liquid.

[0024] The conveying assembly includes a suction pipe 23, one end of which is connected to the inside of the cleaning tank 2, and the other end of which is fixedly connected to a suction pump 24. The end of the suction pump 24 away from the suction pipe 23 is fixedly connected to a feeding pipe 25. The feeding pipe 25 passes through the filter box 26 and is fixedly connected to the filter box 26. The position where the feeding pipe 25 is fixedly connected to the filter box 26 is above the filter plate 27. The conveying assembly is used to convey the mixture of cleaned iron powder particles and cleaning liquid to the filter plate 27.

[0025] Working principle of this invention: Firstly, when filtering and cleaning iron powder particles, the motor 5 is started, driving the output shaft fixedly connected to its output end to rotate. The rotation of the output shaft drives the rotating plate 6 fixedly connected to it to rotate. The rotation of the rotating plate 6 drives the first connecting rod 7 fixedly connected to the fixed rod 8 to rotate. The rotation of the first connecting rod 7 drives the second connecting rod 9 rotatably connected to it to reciprocate. The reciprocating motion of the second connecting rod 9 drives the first rotating shaft 10 rotatably connected to it to move up and down within the first mounting shell 4 and the first bevel gear 14. The rotation of the output shaft drives the second rotating shaft 31 to rotate through the synchronous belt 16. The rotation of the second rotating shaft 31 drives the first rotating shaft 31 to rotate. The second bevel gear 15, which is fixedly connected to it, rotates. The rotation of the second bevel gear 15 drives the first bevel gear 14, which is meshed with it, to rotate. The rotation of the first bevel gear 14 drives the snap-fit ​​plate 13, which is snapped with it, to rotate. The rotation of the snap-fit ​​plate 13 drives the first rotating shaft 10, which is fixedly connected to it, to move up and down while rotating. When the first rotating shaft 10 slides upward, the spring 12 is in the compression stage, and the mechanism stores energy. When the first rotating shaft 10 slides downward, the spring 12 is in the release stage. The spring 12 assists the first rotating shaft 10 to move quickly, making it easier to quickly disperse the agglomerated iron powder particles and improve cleaning efficiency.

[0026] Secondly: The first rotating shaft 10 moves up and down while simultaneously rotating, causing the first stirring rod 17, which is fixedly connected to it, to move up and down and rotate simultaneously. The rotation of the first stirring rod 17 causes the second mounting shell 18, which is fixedly connected to it, to rotate. The rotation of the second mounting shell 18 causes the second stirring rod 21 to revolve, which in turn causes the stirring blade 22, which is fixedly connected to it, to revolve. The rotation of the first stirring rod 17 causes the third bevel gear 19, which is fixedly connected to it, to rotate. The rotation of the third bevel gear 19 causes the fourth bevel gear 20, which meshes with it, to rotate. The rotation of the fourth bevel gear 20 causes the second stirring rod 21, which is fixedly connected to it, to rotate on its own axis. The rotation of the second stirring rod 21 causes the stirring blade 22 to rotate on its own axis. The simultaneous up-and-down movement and rotation of the first stirring rod 17, along with the simultaneous up-and-down movement and revolve and rotation of the stirring blade 22, enhances the fluidity and shear force of the cleaning fluid through multi-dimensional motion, ensuring thorough dispersion of iron powder particles, reducing cleaning dead zones, increasing product purity, improving cleaning efficiency, and reducing subsequent processing costs.

[0027] Finally: The conveying assembly transports the cleaned iron powder particles and cleaning liquid mixture to the top of the filter plate 27. The vacuum pump 28 is started to create a negative pressure below the filter plate 27, allowing the cleaning liquid to pass through the filter plate 27 and enter the bottom of the filter box 26. The iron powder remains on the surface of the filter plate 27 to form a filter cake. The filter box 26 is then opened to remove the filter cake.
