[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0020] like Figure 1 As shown in the figure, this utility model embodiment proposes an aqueous pigment filtration device, including a housing 1 and a filter cylinder 2 disposed within the housing 1. The device also includes a motor 12, a rotating sleeve 4, several stirring rods 3, an annular ring 7, and a lifting assembly. The rotating sleeve 4 is disposed inside the filter cylinder 2 and rotatably connected to the top of the filter cylinder 2, and the rotating sleeve 4 and the filter cylinder 2 are coaxially arranged. The motor 12 is fixedly disposed on the top of the filter cylinder 2 to drive the rotating sleeve 4 to rotate. The stirring rods 3 are arranged around the rotating sleeve 4 and fixedly connected to the rotating sleeve 4, and the stirring rods 3 are horizontally arranged. The annular ring 7 is coaxial with the filter cylinder 2 and disposed inside the filter cylinder 2. The outer wall of the annular ring 7 is provided with an annular shovel 8 that contacts the side wall of the filter cylinder 2. The annular shovel 8 is inclined upwards near the filter cylinder 2, causing impurities to fall onto the annular ring 7. The lifting assembly is used to control the vertical movement of the annular ring 7. In this embodiment, several support blocks 5 are fixedly disposed on the inner wall of the housing 1 to reduce the shaking of the filter cylinder 2, and a discharge port is provided at the bottom of the housing 1. A material reduction hole is provided at the top of the filter cylinder 2.

[0021] like Figure 1 As shown, preferably, the top of the outer shell 1 is provided with a top cover 11, the diameter of which is smaller than the inner diameter of the annular ring 7. A connecting bracket 10 connected to the outer shell 1 is provided on the top cover 11. A groove 6 is provided at the bottom of the outer shell 1, and the bottom of the filter cylinder 2 is adapted to the groove 6, making the filter cylinder 2 and the outer shell 1 relatively stable. The top cover 11 prevents dust from falling during stirring. A gap is provided between the side of the top cover 11 and the filter cylinder 2, facilitating the passage of the annular ring 7 as it moves upwards, allowing workers to clean impurities from the top of the annular ring 7. A fixing sleeve 14 is fixedly provided at the connection point between the filter cylinder 2 and the top cover 11, the fixing sleeve 14 serving to make the rotation of the rotating sleeve 4 more stable.

[0022] like Figure 2 As shown, preferably, the motor 12 is fixedly mounted on the top cover 11, and a first gear 13 is fixedly mounted on the output shaft 26 of the motor 12. A second gear 15 is fixedly mounted on the top of the rotating sleeve 4, and the first gear 13 and the second gear 15 mesh. When the motor 12 rotates, it drives the rotating sleeve 4 to rotate through the first gear 13 and the second gear 15, so that the stirring rod 3 stirs inside the filter cylinder 2.

[0023] like Figure 2 , 4 As shown, preferably, the lifting assembly includes a connecting sleeve 16, a screw 9, a third gear 22, several first connecting rods 21, a fourth gear 17, and a closing unit. The connecting sleeve 16 is located on top of the rotating sleeve 4 and is threadedly connected to the screw 9. The outer wall of the connecting sleeve 16 is rotatably connected to the connecting frame 10. In this embodiment, an annular groove is provided on the lower outer wall of the connecting sleeve 16, and the connecting frame 10 is rotatably connected to the annular groove, so that the connecting sleeve 16 is axially fixed. The third gear 22 is fixedly disposed outside the connecting sleeve 16, and the fourth gear 17 is fixedly disposed on top of the output shaft 26 of the motor 12. The third gear 22 and the fourth gear 17 mesh. The first connecting rods 21 are evenly and vertically wrapped around the top of the annular ring 7. The bottom of the first connecting rods 21 is fixedly connected to the annular ring 7. After the first connecting rods 21 extend upward to the outside of the filter cartridge 2, a transverse rod 25 is fixedly disposed thereon. The transverse rod 25 is fixedly connected to the screw 9. The screw 9 has a sliding groove 23 on its exterior. The sliding groove 23 is vertical and parallel to the center line of the screw 9. The connecting frame 10 and the sliding groove 23 are slidably connected in the vertical direction, so that the screw 9 can only move axially. The closing unit allows the fourth gear 17 to connect or disconnect from the output shaft 26 of the motor 12. The rotation of the motor 12 drives the fourth gear 17 to rotate, which in turn drives the third gear 22 and the connecting sleeve 16 to rotate. When the connecting sleeve 16 rotates, it causes the internal screw 9 to move axially. The upward-moving screw 9 drives the annular ring 7 to move upward through the first connecting rod 21. The annular shovel plate 8 on the outer side of the annular ring 7 causes impurities inside the filter cartridge 2 to be removed.

[0024] like Figure 3As shown, preferably, the closing unit includes a limiting sleeve 20 and a limiting rod 19. The limiting sleeve 20 is a cylindrical structure, coaxial with the fourth gear 17 and fixedly connected to the bottom surface of the fourth gear 17. The output shaft 26 of the motor 12 extends into the interior of the limiting sleeve 20. The side wall of the limiting sleeve 20 is provided with a through hole, and the output shaft 26 is provided with a threaded hole laterally. The limiting rod 19 passes through the through hole and is threadedly connected to the output shaft 26. A second connecting rod 18 is provided at the top center of the fourth gear 17, and the second connecting rod 18 is rotatably connected to the connecting frame 10. When regular filtration is performed and the side wall of the filter cartridge 2 does not need to be cleaned, the limiting rod 19 is removed. When the output shaft 26 of the motor 12 rotates, the output shaft 26 and the connecting sleeve 16 will not rotate synchronously, and thus will not drive the fourth gear 17 to rotate. The annular ring 7 will remain fixed relative to the filter cartridge 2. When periodically cleaning the side of the filter cartridge 2, insert the limiting rod 19 through the through hole and connect it to the threaded section on the output shaft 26 to drive the fourth gear 17 to rotate. During cleaning, when the annular ring 7 moves out to the top of the filter cartridge 2, the motor 12 stops working.

[0025] Preferably, a slag discharge hole 24 is provided at the center of the bottom of the filter cartridge 2, and the slag discharge hole 24 is connected to the outside of the outer shell 1. The slag discharge hole 24 is equipped with a valve to discharge impurities that fall to the bottom of the filter cartridge 2.

[0026] Preferably, the bottom of the rotating sleeve 4 is closed to prevent the pigment from entering the interior of the rotating sleeve 4 and affecting the sliding of the screw 9 inside the rotating sleeve 4.

[0027] Preferably, the top surface of the annular ring 7 is provided with an annular chamber with an upward opening on the side near the annular shovel plate 8. The impurities shoveled off by the annular shovel plate 8 fall into the chamber, and the annular ring 7 moves upward to the outside of the filter cartridge 2 for easy cleaning by the staff.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
