[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Reference Figure 1-4 This utility model provides an aquaculture wastewater filtration and treatment device, comprising:

[0026] The filter assembly includes a filter box 1, in which several filter screens 2 are slidably arranged, arranged vertically. The filter box 1 has an inlet 3 and an outlet 4, with the inlet 3 located at the top of the filter box 1 and the outlet 4 located at the bottom of the filter box 1. The filter screens 2 are arranged at an angle. The filter box 1 has a first drain outlet 5. A collection tank 6 is fixedly connected to the filter box 1, and the collection tank 6 is located below the first drain outlet 5.

[0027] The cleaning assembly includes two cleaning boxes 7, which are fixedly connected to both sides of the filter box 1. Both the filter box 1 and the cleaning box 7 have several through holes, and the filter screen 2 is located in the through holes. A washing mechanism is provided inside the cleaning box 7, and the washing mechanism abuts against the filter screen 2. A second drain port 8 is provided on the cleaning box 7, and a pulling mechanism is fixedly connected to the cleaning box 7. The pulling mechanism is drivenly connected to the filter screen 2.

[0028] In this device, filter screens 2 are used to filter aquaculture wastewater. Several filter screens 2 have different mesh sizes to filter debris of different sizes. A pulling mechanism is used to pull the filter screens 2. The inlet 3 is used to introduce aquaculture wastewater into the filter box 1. The wastewater flows from top to bottom into the filter box 1 and is filtered through multiple layers of filter screens 2. The lower end of the inclined filter screens 2 is flush with the first drain outlet 5. Debris filtered by the filter screens 2 can be discharged through the first drain outlet 5, or it can be manually scraped off by staff. The debris can first enter the collection tank 6, which is then cleaned periodically. The filter box 1 may also have openings... The drain outlet is located inside the collection tank 6, facilitating the return of water from the collection tank 6 to the filter box 1. The filter screen 2 is relatively long and is located in both the filter box 1 and the cleaning tank 7. Regardless of which side's pulling mechanism pulls the filter screen 2, there will always be a filter screen 2 inside the filter box 1. Both sides of the cleaning tank 7 have washing mechanisms. When the filter screen 2 in the filter box 1 has been used for a long time, the filter screen 2 can be moved by pulling the filter screen 2 on one side, while the pulling mechanism on the other side releases the filter screen 2. During the movement of the filter screen 2, the washing mechanism washes the filter screen 2, and the wastewater from the washing can be discharged through the second drain outlet 8.

[0029] The scheme is further optimized. The pulling mechanism includes a second motor 9. The output end of the second motor 9 is fixedly connected to a winding roller 10. A rope 11 is wound on the winding roller 10. A through hole is opened on the cleaning box 7. The rope 11 passes through the through hole and is fixedly connected to the filter screen 2. A second mounting plate 18 is fixedly connected to the cleaning box 7. The second motor 9 is fixedly connected to the second mounting plate 18.

[0030] The second motor 9 drives the winding roller 10 to rotate, and the winding roller 10 winds up the rope 11. At this time, the winding roller 10 on the other side releases the rope 11, which moves in conjunction with the filter screen 2. The second motor 9 can rotate forward and reverse.

[0031] The washing mechanism is further optimized by including an upper washing roller 12 and a lower washing roller 13. The upper washing roller 12 and the lower washing roller 13 are rotatably connected inside the washing box 7. The upper washing roller 12 and the lower washing roller 13 are located on the upper and lower sides of the filter screen 2, respectively. Both the upper washing roller 12 and the lower washing roller 13 abut against the filter screen 2. A first motor 14 is fixedly connected to the washing box 7. The first motor 14 is driven by the upper washing roller 12 and the lower washing roller 13.

[0032] The upper cleaning roller 12 and the lower cleaning roller 13 are used to clean the filter screen 2. During the movement of the filter screen 2, the first motor 14 drives the upper cleaning roller 12 and the lower cleaning roller 13 to rotate and clean the filter screen 2.

[0033] The scheme is further optimized. The upper cleaning roller 12 and the lower cleaning roller 13 extend out of the cleaning box 7. The upper cleaning roller 12 and the lower cleaning roller 13 are both fixedly connected to the first gear 15. The two first gears 15 mesh. The output end of the first motor 14 is fixedly connected to the second gear 16. The second gear 16 meshes with the first gear 15. The cleaning box 7 is fixedly connected to the first mounting plate 17. The first motor 14 is fixedly connected to the first mounting plate 17.

[0034] The first motor 14 drives the second gear 16 to rotate, and the second gear 16 drives the first gear 15 to rotate. Since the two first gears 15 mesh, both the upper cleaning roller 12 and the lower cleaning roller 13 can rotate.

[0035] The solution is further optimized by fixing several flushing pipes 19 inside the cleaning tank 7. Several water spray holes are opened on the flushing pipes 19, and the flushing pipes 19 are connected to the water supply pipe.

[0036] Water in the flushing pipe 19 is sprayed out from the spray nozzle to flush the filter screen 2, making the filter screen 2 cleaner.

[0037] The design is further optimized by fixing several connecting rings on the filter screen 2, and fixing the rope 11 to the connecting rings.

[0038] The connecting ring is used to connect rope 11 and filter screen 2.

[0039] The design has been further optimized so that several trays 20 are fixedly connected inside both the cleaning box 7 and the filter box 1, and the filter screen 2 is located on the trays 20.

[0040] The support plate 20 is used to support the filter screen 2, making the filter screen 2 move more smoothly.

[0041] The design is further optimized by attaching a protective cover 21 to the outside of the cleaning tank 7, with the first motor 14 located inside the protective cover 21, and several support legs fixedly connected to both the cleaning tank 7 and the filter tank 1.

[0042] The protective cover 21 is used to protect the first motor 14.

[0043] The device is used as follows: the wastewater to be filtered enters the filter box 1 through the inlet 3. The wastewater flows from top to bottom and is filtered through multiple layers of filter screens 2. Because the lower end of the inclined filter screen 2 is flush with the first drain outlet 5, the impurities filtered by the filter screen 2 will enter the collection tank 6 through the first drain outlet 5. The impurities on the filter screen 2 can also be manually scraped off by the staff. The impurities can first enter the collection tank 6, and then the collection tank 6 can be cleaned periodically. When the filter screen 2 in the filter box 1 has been used for a long time, the second motor 9 on one side drives the winding roller 10 to rotate, and the winding roller 10 winds up the rope 11. At this time, the winding on the other side... Roller 10 releases rope 11 to move in conjunction with filter screen 2. First motor 14 drives second gear 16 to rotate, and second gear 16 drives first gear 15 to rotate. Since the two first gears 15 mesh, both upper cleaning roller 12 and lower cleaning roller 13 can rotate, allowing the filter screen to be cleaned during the movement of filter screen 2. Water in flushing pipe 19 is sprayed out from spray hole to flush filter screen 2. The wastewater from washing can be discharged through second drain port 8. This utility model reduces the workload of manual cleaning of filter screen 2 by workers and avoids stopping the filtration work. Filter screen 2 can be cleaned during the filtration process.
