[0023] It should be understood that terms such as “having”, “including” and “comprising” used herein do not specify the existence or addition of one or more other elements or combinations thereof.

[0024] See also Figures 1 to 3 A dye recovery device for dyeing includes a recovery box 1, a filter cartridge 2 and a cleaning structure 3. The interior of the recovery box 1 is divided from top to bottom into a primary filter chamber 12 and a secondary filter chamber 13 by a partition plate 11. The recovery box 1 is used to provide a recovery place. The recovery box 1 can be square or cylindrical. The top of the primary filter chamber 12 is provided with a liquid inlet pipe 121, and the bottom of the secondary filter chamber 13 is provided with a liquid discharge pipe 131. The liquid inlet pipe 121 is used for the dye to be recovered to enter the primary filter chamber 12, and the liquid discharge pipe 131 is used for the dye to be filtered and treated to flow out, so as to reuse the dye. Furthermore, a first impurity discharge port 122 is provided at the bottom side of the primary filter chamber 12, and the first impurity discharge port 122 is in a normally closed state. When it is necessary to discharge impurities inside the primary filter chamber 12, the first impurity discharge port 122 can be opened to discharge the trapped impurities; a second impurity discharge port 132 is provided at the bottom of the secondary filter chamber 13, and the caliber of the second impurity discharge port 132 is consistent with the caliber of the bottom port of the filter cartridge 2, and the second impurity discharge port 132 is in a normally closed state. When it is necessary to discharge impurities inside the filter cartridge 2, the second impurity discharge port 132 can be opened to discharge them, so that the impurity discharge operation is simple and convenient;

[0025] The filter cartridge 2 is arranged in the primary filter cavity 12 and its bottom port extends downward to the bottom of the secondary filter cavity 13; the surface of the filter cartridge 2 located inside the primary filter cavity 12 has a plurality of first filter holes 21, and the surface of the filter cartridge 2 located inside the secondary filter cavity 13 has a plurality of second filter holes 22. It should be understood that the aperture of the second filter hole 22 is smaller than the aperture of the first filter hole 21;

[0026] The cleaning mechanism 3 includes a first threaded rod 31 and a second threaded rod 32 rotatably arranged inside and outside the filter cartridge 2, the first threaded rod 31 is threadedly connected with an inner wall brush plate 4 in contact with the inner wall of the filter cartridge 2, and the inner wall brush plate 4 slides through a first guide column 41 fixed in the filter cartridge 2, the top of the first guide column 41 is welded or bolted to the top surface of the filter cartridge 2, the second threaded rod 32 passing through the partition plate 11 is threadedly connected with a first outer wall brush plate 51 in contact with the outer wall of the filter cartridge 2 inside the primary filter chamber 12, and a second outer wall brush plate 52 in contact with the outer wall of the filter cartridge 2 inside the secondary filter chamber 13 from top to bottom, and the first outer wall brush plate 51 and the second outer wall brush plate 52 slide through the second guide column 53 passing through the partition plate 11 respectively. It is worth noting that the impurities cleaned by the second outer wall brush plate 52 fall into the secondary filter chamber 13 and can be discharged through the drain pipe 131. Of course, a third impurity discharge port can also be provided in the secondary filter chamber 13 to discharge impurities inside the secondary filter chamber 13 after cleaning is completed. It is worth noting that the bottom end of the first threaded rod 31 can be rotatably mounted on a support seat, and the support seat is connected to the bottom inner wall of the filter cartridge 2 via three support rods. The setting of the support seat can further facilitate the rotation stability of the first threaded rod 31 .

[0027] Specifically, the primary filter chamber 12, the secondary filter chamber 13 and the first filter hole 21 and the second filter hole 22 of the filter cartridge 2 cooperate to achieve double filtration of the dye, ensure the filtering and impurity removal effect of the dye, which is beneficial to ensure the quality of the dye when it is reused and enhance the recycling effect of the dye; the setting of the filter cartridge 2 vertically passing through the primary filter chamber 12 and the secondary filter chamber 13 facilitates the debris intercepted by the filter cartridge 2 to fall to the bottom for discharge; the cleaning mechanism 3 cleans the filter cartridge, and the cleaning can be completed without disassembling the filter cartridge, saving the time of disassembly and assembly, which is beneficial to improve the overall recovery efficiency; the first threaded rod 31 rotates to drive the inner wall brush plate 4 to move up and down to clean the inner wall of the filter cartridge 2, and the second threaded rod 32 rotates to drive the first outer wall brush plate 51 and the second outer wall brush plate 52 to move up and down to clean the outer wall of the filter cartridge 2, thereby achieving the cleaning of the inner and outer surfaces of the filter cartridge 2 at the same time, enhancing the cleaning effect, ensuring that the first filter hole 21 and the second filter hole 22 of the filter cartridge 2 are cleaned, and accelerating the cleaning efficiency.

[0028] Working principle: the dye liquid to be recycled enters the primary filter chamber 12 through the liquid inlet pipe 121, and then the dye is filtered through the first filter hole 21 of the filter cartridge 2, and the debris is intercepted outside the filter cartridge 2 inside the primary filter chamber 12. After entering the filter cartridge 2, the dye flows downward to the bottom of the filter cartridge 2, and then passes through the second filter hole 22 of the filter cartridge 2 for secondary filtration and impurity removal, which effectively ensures that the dye is clean. The dye flows into the secondary filter chamber 13 through the second filter hole 22 and is finally discharged through the drain pipe 131 for centralized collection and utilization; after using for a period of time, when the filter cartridge 2 needs to be cleaned, the first threaded rod 31 and the second threaded rod 32 are driven to rotate, so that the inner wall brush plate 4 and the first outer wall brush plate 51 and the second outer wall brush plate 52 move up and down, thereby realizing simultaneous brushing and cleaning of the inner and outer surfaces of the filter cartridge 2, so that the debris on the inner and outer surfaces of the filter cartridge 2 is brushed off and falls to the bottom, and finally the debris falling at the bottom of the filter cartridge 2, the bottom of the primary filter chamber 12, and the bottom of the secondary filter chamber 13 are discharged to complete the cleaning.

[0029] In the above example, the top end of the first threaded rod 31 passes through the top of the recovery box 1 and is transmission-connected to the output shaft of the first motor 33, and a driving gear 34 is provided at the upper end of the first threaded rod 31, and a driven gear 35 is fixed to the top end of the second threaded rod 32, and the driven gear 35 is meshed with the driving gear 34. Specifically, the smooth section of the first threaded rod 32 extends out of the recovery box 1 through the transmission structure and the output shaft of the first motor 33. The transmission structure belongs to the prior art, as long as the first motor 33 can drive the first threaded rod 31 to rotate, The middle part of the second threaded rod 32 has a smooth section passing through the partition plate 11, and the diameter of the driving gear 34 is smaller than the diameter of the driven gear 35, so that the rotation speed of the first threaded rod 31 is faster than the rotation speed of the second threaded rod 32, and thus the lifting speed of the inner wall brush plate 4 is faster than the speed of the first outer wall brush plate 51 and the second outer wall brush plate 52, so that when the inner wall brush plate 4 moves downward to the bottom of the filter cylinder 2, the first outer wall brush plate 51 and the second outer wall brush plate 52 move to the bottom of the primary filter chamber 12 and the secondary filter chamber respectively. By adopting this technology, the purpose of saving energy is achieved.

[0030] During the actual use of the present invention, since the yarn and other debris mixed in the dye are easily entangled and adhered to the first threaded rod 31 and the second threaded rod 32, it is easy to affect the movement of the inner wall brush plate 4, the first outer wall brush plate 51, and the second outer wall brush plate 52, thereby affecting the cleaning effect of the filter cartridge 2. The inner wall brush plate 4 is threadedly connected to the first threaded rod 31 through the first lifting block 41, and the first outer wall brush plate 51 and the second outer wall brush plate 52 are both connected to the second threaded rod 32 through the second lifting block 54. The upper and lower sides of the lifting block are provided with bristles 6 that contact the surface of the threaded rod. The setting of the bristles 6 allows the lifting block to move to brush off the debris adhered to the first threaded rod 31 and the second threaded rod 32, so that the lifting block can move smoothly along the threaded rod, thereby ensuring that the inner wall brush plate 4 and the first outer wall brush plate 51 and the second outer wall brush plate 52 can move up and down smoothly, thereby ensuring the cleaning effect of the filter cartridge 2.

[0031] In order to further enhance the filtering effect, it also includes a vertical shaft 7 with openings at both ends, the vertical shaft 7 is sleeved on the top of the first threaded rod 31, and the vertical shaft 7 can rotate through the top of the recovery box 1; the top of the vertical shaft 7 is connected to the output shaft of the second motor 71, and the bottom of the vertical shaft 7 is connected to the impurity removal unit 8 through the connecting rod 72, and the impurity removal unit 8 rotates around the filter cartridge 2, the second motor 71 drives the vertical shaft 7 to rotate, and the vertical shaft 7 connecting rod 72 rotates with the impurity removal unit 8, and further, the impurity removal unit 8 includes a fixed end of the connecting rod 72. An I-shaped frame 81 is provided on the frame 81, and a plurality of winding rods 82 are arranged on the frame 81. A plurality of auxiliary winding rods 83 are arranged between two adjacent winding rods 82. When the impurity removal unit 8 rotates around the filter cylinder 2 located inside the primary filter chamber 12, it can wind up fine yarn, fine wire and other debris, thereby enhancing the filtering and impurity removal effect. The winding rod 82 cooperates with the auxiliary winding rod 83 to perform a rotational winding and impurity removal operation. At the same time, the impurity removal unit 8 can promote the flow of dye while rotating, so that the dye passes through the first filter hole 21 of the filter cylinder 2 and enters the interior of the filter cylinder 2, thereby accelerating the filtering recovery efficiency.

Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention.
