[0029] Recycled cotton is a fiber made from recycled materials such as waste textiles or plastic bottles. After a series of processing techniques, the waste materials are decomposed, fiberized and reprocessed to finally make a fiber material similar to cotton.

[0030] At present, the Chinese utility model patent application with publication date of July 12, 2022 and publication number of CN 218596700 U proposes a cleaning liquid separation device for a washing machine, including a primary filter mechanism provided on one side of a washing tank, the primary filter mechanism including a primary filter box and a first filter

[0031] The first water pump is connected to the outer wall of the primary filter box by bolts, and a secondary filter mechanism is provided on one side of the primary filter box, and the secondary filter mechanism includes a secondary filter box, a filter plate and a threaded pipe. The utility model can filter out large particles of impurities and debris in the cleaning liquid to avoid clogging the pipeline and the first water pump, thereby improving practicality, and can filter tiny impurities from the cleaning liquid again, while preventing tiny impurities from clogging the filter cotton, thereby improving the cleaning effect.

[0032] The cleaning liquid separation device in the related art needs to stop the filtering operation, open the secondary filter box, and take out the first filter for cleaning after filtering the cleaning liquid. This will affect the working efficiency of the filter and cause wear to the overall structure of the filter.

[0033] Based on this, in order to improve the problem that filtered debris is difficult to clean in the related art, the embodiments of the present application provide the following solution.

[0034] Please also read Figure 1 and Figure 3 , the embodiment of the present application provides a filtering device for cleaning liquid in the production of recycled cotton, including a filter box 1, a liquid inlet pipe 3, a liquid outlet pipe 2, a flushing pipe 4, a sealing assembly 7, a filter assembly 6 and a cleaning assembly 5, the filter box 1 is provided with a first opening, a second opening, a third opening and a fourth opening, the liquid inlet pipe 3, the liquid outlet pipe 2 and the flushing pipe 4 are all arranged on the filter box 1, the liquid inlet pipe 3 is connected with the filter box 1 through the second opening, the liquid outlet pipe 2 is connected with the filter box 1 through the third opening, the flushing pipe 4 is connected with the filter box 1 through the fourth opening, the cleaning assembly 5 includes a cleaning disk 51, a limiting disk 52 and a cylinder 53, the cylinder 53 is arranged on the filter box 1 through the sealing assembly 7, the cleaning disk 51 is arranged on the output shaft of the cylinder 53, the limiting disk 52 is arranged in the flushing pipe 4, the filter assembly 6 is used to filter the cleaning liquid, and the sealing assembly 7 is used to block the first opening.

[0035] From the above, it can be seen that the embodiment of the present application provides a filtering device for cleaning liquid in the production of recycled cotton. When filtering the cleaning liquid, the cleaning liquid enters the interior of the filter box 1 through the second opening from the liquid inlet pipe 3, passes through the filter assembly 6, and flows out from the liquid outlet pipe 2 through the second opening. When it is necessary to clean the filtered debris, the cylinder 53 drives the cleaning plate 51 to move up and down repeatedly in the filter box 1, and at the same time opens the limit plate 52 in the flushing pipe 4. The movement of the cleaning plate 51 drives the filtered debris to flow, and the filter cartridge 61 around the cleaning plate 51 is partially backwashed due to the Bernoulli effect, and backflow occurs. The debris flows out of the flushing pipe 4, and then the limit plate 52 is closed.

[0036] With such an arrangement, a filtering device for cleaning liquid in recycled cotton production provided in an embodiment of the present application can, through the arrangement of a cylinder 53, a cleaning plate 51, a flushing pipe 4 and a limiting plate 52, enable the filter component 6 to be cleaned after filtering the cleaning liquid without stopping the filtering operation, thereby improving the filtering efficiency.

[0037] In some embodiments, please refer to Figure 1 and Figure 3 The filter assembly 6 includes a filter cartridge 61 and a fixing ring 62. The filter cartridge 61 is arranged in the filter box 1. The fixing ring 62 is connected to the inner circumferential surface of the filter box 1 by bolts. One end of the filter cartridge 61 abuts against a side of the filter box 1 close to the second opening, and the other end abuts against a side of the fixing ring 62 close to the second opening.

[0038] With such arrangement, the cleaning liquid enters the liquid inlet pipe 3 through the second opening into the interior of the filter cartridge 61, is filtered by the filter cartridge 61, and then flows out from the third opening to the liquid outlet pipe 2, thereby ensuring that the cleaning liquid entering the filter box 1 must pass through the filter cartridge 61, thereby ensuring the integrity of the cleaning liquid filtration. The setting of the fixing ring 62 can ensure that the filter cartridge 61 will not shake inside the filter box 1, thereby improving the stability of the structure.

[0039] In some embodiments, please refer to Figure 1 and Figure 3 The sealing assembly 7 includes a sealing cover 71 and a sealing ring 72 . The sealing ring 72 is disposed on a side of the filter box 1 close to the first opening, and a side of the sealing ring 72 away from the filter box 1 abuts against the sealing cover 71 .

[0040] With such arrangement, when the cleaning disc 51 reciprocates in the filter cartridge 61, the filter cartridge 61 portion around the cleaning disc 51 is backwashed due to the Bernoulli effect, resulting in backflow, so that the cleaning liquid does not flow out from the first opening, and it is also convenient to open the filter box 1 for repair and maintenance of the interior, thereby increasing the service life of the filter box 1.

[0041] In some embodiments, please refer to Figure 1 and Figure 3 The sealing assembly 7 also includes connecting bolts 73. The sealing cover 71 is provided with a plurality of first threaded holes. A side of the filter box 1 close to the first opening is provided with a plurality of second threaded holes. The first threaded holes and the second threaded holes are connected with a plurality of connecting bolts 73.

[0042] With such arrangement, after the sealing cover 71 and the sealing ring 72 are abutted, the connecting bolt 73 passes through the first threaded hole and the second threaded hole to tightly connect the sealing cover 71, the sealing ring 72 and the filter box 1 together, thereby improving the stability of the structure.

[0043] In some embodiments, please refer to Figure 1 and Figure 3 A chamfer 8 is formed on one side of the cleaning disk 51 close to the second opening.

[0044] With such arrangement, when the cleaning disc 51 reciprocates in the filter cartridge 61, the chamfer 8 provided on the cleaning disc 51 can make it easier and more convenient to press down the cleaning disc 51, and the cleaning liquid will also flow along the chamfer 8, thereby improving the convenience of the reciprocating motion of the cleaning disc 51.

[0045] In some embodiments, please refer to Figure 1 and Figure 3 A driving motor 9 is also provided on the flushing pipe 4 , and an output shaft of the driving motor 9 passes through the flushing pipe 4 and is transmission-connected to the limiting plate 52 .

[0046] With such an arrangement, when the filter cartridge 61 needs to be cleaned, the cylinder 53 drives the cleaning disk 51 to reciprocate in the filter cartridge 61, so that the cleaning disk 51 forms a Bernoulli effect around the filter cartridge 61, resulting in backflow, which drives debris to flow out of the flushing pipe 4. At this time, the driving motor 9 needs to rotate to drive the limit plate 52 to rotate so that the limit plate 52 no longer blocks the flushing pipe 4. After cleaning is completed, the limit plate 52 is rotated to close the flushing pipe 4. This ensures that the flushing pipe 4 will not be opened until cleaning is needed, ensuring that the cleaning liquid will not flow out of the flushing pipe 4 during filtration, thereby improving the efficiency of cleaning liquid filtration.

[0047] In some embodiments, please refer to Figure 1 and Figure 3 The filter box 1 is also provided with an electric control box 10 , and the cylinder 53 and the drive motor 9 are both connected to the electric control box 10 via electrical signals.

[0048] With such arrangement, the lifting and lowering of the air cylinder 53 can be controlled by the electric control box 10 , and the driving motor 9 can be controlled by the electric control box 10 to drive the limit plate 52 to rotate.

[0049] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
