[0039] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] Please refer to Figures 1 to 2 This utility model provides a sludge collection device for recirculating aquaculture, including a filter box 1, a filter plate 5, a sealing mechanism 6, a rotating mechanism 7, and a three-way control valve 8.

[0041] The top and bottom of the filter box 1 are respectively equipped with an inlet pipe 2 and an outlet pipe 3;

[0042] The liquid outlet pipe 3 is connected to the three-way control valve 8, and the two drain ports of the three-way control valve 8 are connected to the sludge collection tank 9 and the disinfection tank 10 respectively.

[0043] The filter box 1 is equipped with a partition 4, and the partition 4 has mounting holes.

[0044] The filter plate 5 is installed in the mounting hole and connected to the rotating mechanism 7;

[0045] The sealing mechanism 6 is installed in the mounting hole and is used to seal the filter plate 5 after it is rotated to the mounting hole.

[0046] In use, the circulating water from the pond enters the filter box 1, is filtered by the filter plate 5, and then enters the disinfection box 10. When a lot of impurities accumulate on the filter plate 5, the three-way control valve 8 switches to connect to the sludge collection box 9. At the same time, the rotating mechanism 7 drives the filter plate 5 to rotate, and the sealing mechanism 6 seals the rotated filter plate 5 with the mounting hole. Water is then injected into the filter box 1 to transport the accumulated impurities to the sludge collection box 9. After a period of time (usually 10-30 seconds), the three-way control valve 8 switches to connect to the disinfection box 10 again to achieve normal water treatment. This application can comprehensively and effectively impact and remove impurities on the filter plate 5, thoroughly transporting the accumulated impurities to the sludge collection box 9, avoiding impurity residue, restoring the filtration performance of the filter plate 5, and thus continuously maintaining a high efficiency in sludge collection and water purification.

[0047] In this embodiment, the rotating mechanism 7 includes a servo motor 71 and a drive shaft 72;

[0048] One end of the drive shaft 72 is connected to the filter plate 5, and the other end of the drive shaft 72 is sequentially passed through the partition 4 and the filter box 1 and fixedly connected to the servo motor 71. The connection between the drive shaft 72 and the partition 4 is mechanically sealed to prevent media leakage.

[0049] In use, the servo motor 71 controls the rotation of the drive shaft 72 to achieve the flipping control of the filter plate 5.

[0050] In this embodiment, the sealing mechanism 6 includes a sealing groove, an air-inflatable sealing strip 61, an inflation control component 62, and an deflation control component 63;

[0051] The sealing groove is formed on the inner wall of the mounting hole and has an arc-shaped structure, which surrounds the filter plate 5.

[0052] An air-inflatable sealing strip 61 is installed in a sealing groove, and the air-inflatable sealing strip 61 connects the inflation control component 62 and the deflation control component 63.

[0053] In use, the venting control component 63 releases the gas from the air-expanding sealing strip 61, creating a gap between the filter plate 5 and the mounting hole. This allows the filter plate 5 to rotate in conjunction with the rotating mechanism 7. After the filter plate 5 rotates, the inflation control component 62 injects high-pressure gas into the air-expanding sealing strip 61, causing it to expand. The expanded sealing strip 61 fills the gap between the filter plate 5 and the mounting hole, achieving a sealing effect. The sealing mechanism 6 is located inside the mounting hole and can provide a sealing connection after the filter plate 5 rotates. This design ensures that the backwash water flow does not leak during backwashing, maintains sufficient backwash pressure, and allows the backwashing operation to proceed smoothly, improving the reliability and stability of the device operation.

[0054] In this embodiment, the inflation control component 62 includes an inflation pump 621, an inflation pipe 622, and a first control valve 623; the inflation pump 621 is connected to the air-expanding sealing strip 61 through the inflation pipe 622, and the first control valve 623 is installed on the inflation pipe 622.

[0055] In this embodiment, the venting control component 63 includes a venting pump 631, a venting pipe 632, and a second control valve 633; ​​the venting pump 631 is connected to the air-expanding sealing strip 61 through the venting pipe 632, and the second control valve 633 is installed on the venting pipe 632.

[0056] In this embodiment, a water flow sensor is installed inside the liquid outlet pipe 3, and the sealing mechanism 6, the rotating mechanism 7, and the three-way control valve 8 of the water flow sensor are all electrically connected to the PLC controller.

[0057] During use, the discharge status of the outlet pipe 3 is monitored by the water flow sensor. When the water flow rate is lower than the threshold, it indicates that the filter plate 5 is severely clogged. The PLC controller realizes the flipping and backflushing of the filter plate 5 through the sealing mechanism 6 and the rotating mechanism 7 to achieve automated dirt collection.

[0058] In this embodiment, the disinfection box 10 is equipped with an ultraviolet disinfection lamp. The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and therefore require no further explanation. The scope of protection of this utility model does not involve improvements to the software or methods.

[0059] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.

[0060] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
