[0002] In the field of aquaculture, the organic matter in the aquaculture water mainly comes from fish feces and remaining feed, and most of it exists in the form of particles at the bottom of the pond. Currently, in relatively good industrialized recirculating aquaculture, sedimentation tanks or rotary separation bins are used to separate and remove particulate pollutants, and then the water quality is biochemically filtered. These methods have many deficiencies. The main manifestations are as follows: The large water flow has a large acting force on particulate pollutants, the separation efficiency of sedimentation tanks or rotary separation bins is low, and to achieve an ideal effect, it is necessary to increase the space of sedimentation tanks or rotary separation bins, and a large amount of water is used during sewage discharge or backwashing sewage discharge. It is necessary to build a powerful filtration system and replace a large amount of water every day to maintain water quality. Doing so has a high construction cost and low water resource utilization rate. Summary of the Invention

[0022] The embodiments will now be described more fully with reference to the accompanying drawings. However, the embodiments may be implemented in many different forms and should not be construed as limited to the embodiments set forth herein. On the contrary, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the embodiments to those of ordinary skill in the art. In the following description, well-known functions or structures are not described in detail because they would obscure the embodiments with unnecessary detail, and throughout the specification, like reference numerals in the drawings denote the same or similar elements.

[0023] Acc Figure 1 Acc is a three-dimensional schematic diagram of an aquaculture water pollution separation system according to the present invention. Acc Figure 2 This is Embodiment 1 of an aquaculture water pollution separation device according to the present invention. An aquaculture water pollution separation system includes an aquaculture water pollution separation device, a first water pump 11 for delivering fish pond water to the aquaculture water pollution separation device, a second water pump 12 for delivering filtered water to the fish pond, and a sewage outlet 7 is connected to a sewage bucket 13.

[0024] The aquaculture water pollution separation device includes an inlet pipe 1. The inlet pipe 1 diverges to form a plurality of first spray pipes 2. The opening and closing and flow rate of the first spray pipes 2 are controlled by a first switch 8. A water pollution separation barrel 3 is rotatably installed on each first spray pipe 2, and the first spray pipe 2 extends along the center line of the water pollution separation barrel 3. The water pollution separation barrel 3 has a conical structure. The small-diameter end 31 of the water pollution separation barrel 3 is rotatably connected to the first spray pipe 2. Filter holes are evenly distributed on the side wall 32 of the water pollution separation barrel 3. The large-diameter end 33 of the water pollution separation barrel 3 is open outward. The first spray pipe 2 sprays water flow from the inside of the water pollution separation barrel 3 toward the side wall 32 to make the water pollution separation barrel 3 rotate; an inner barrel 4, the inner barrel 4 is located below the water pollution separation barrel 3 and is aligned with the filter holes to receive the filtered water. An outlet 41 is provided on the inner barrel 4; an outer barrel 5, the outer barrel 5 is located outside the inner barrel 4 and the water pollution separation barrel 3. The large-diameter end 33 of the water pollution separation barrel 3 is located outside the inner barrel 4 so that sewage flows outward into the outer barrel 5. A sewage outlet 51 is provided at the bottom of the outer barrel 5.

[0025] Appendix Figure 3 Describes the water pollution separation barrel of the aquaculture water pollution separation device according to the present invention. The conical structure includes a bottom plate 34 at the small-diameter end 31, an opening 35 at the large-diameter end 33, and fixed side strips 36 spaced on the side wall 32. A filter screen 37 is detachably installed between the fixed side strips 36. A support column 38 is provided at the opening 35. The first spray pipe 2 passes through the bottom plate 34 and extends along the center line of the water pollution separation barrel 3. One end of the first spray pipe 2 is rotatably connected to the bottom plate 34 and the other end is rotatably connected to the support column 38.

[0026] The inlet pipe 1 diverges along the circumference above each water pollution separation barrel to form a plurality of second spray pipes 6. The second spray pipes 6 are parallel to the first spray pipes 2. The second spray pipes 6 spray water flow from the outside of the water pollution separation barrel 3 toward the side wall to make the water pollution separation barrel rotate, so as to remove the dirt that remains on the filter screen 37 and cannot fall. The second spray pipes 6 spray in a direction opposite to that of the first spray pipes 2, causing the water pollution separation barrel to rotate in the reverse direction, which can make the dirt stuck on the filter screen 37 due to long-term rotation in one direction fall smoothly. The opening and closing and flow rate of the second spray pipes 8 are controlled by a second switch 9. The second spray pipes 8 can also be directly connected to clear water alone. However, since it is only a short-term rapid flushing, directly connecting to the fish pond water will not have too much impact on the final water quality.

[0027] The inlet pipe 1 passes through the bottom of the inner barrel 4 and extends along the circumference to form a third spray pipe 7. The third spray pipe 9 is rotatably arranged above the sewage outlet 51. The opening and closing and flow rate of the third spray pipe 9 are controlled by a third switch 10.

[0028] The fishpond water is transported by the first water pump 11 to the first spray pipe 2 of the aquaculture water pollution separation device. The first spray pipe 2 sprays water flow from the inside of the water pollution separation barrel 3 towards the side wall 32 to make the water pollution separation barrel 3 rotate. The filtered water enters the inner barrel 4. Due to the rotation of the water pollution separation barrel 3, the dirt filtered out on the filter holes will turn and gather on the inner wall as the water pollution separation barrel 3 rotates, and under the action of its own gravity, it will flow into the outer barrel 5 along the large-diameter end 33. In order to prevent the filter holes from being blocked, the first spray pipe 2 is closed under the control of the first switch 8, and the second spray pipe 6 is opened under the control of the second switch 9 and sprays water flow in the opposite direction above the water pollution separation barrel 3 to make the water pollution separation barrel 3 rotate in the opposite direction, so as to spray out the blocked dirt and flow into the outer barrel 5 along with the water flow. In order to prevent dirt from remaining near the sewage outlet 51, the third spray pipe 9 is opened under the control of the third switch 10, and rotates and sprays above the sewage outlet 51 to wash the remaining dirt towards the sewage outlet.

[0029] Appendix Figure 4 This is Embodiment 2 of the aquaculture water pollution separation device according to the present invention; the first spray pipe forms an angle of 0 to 15 degrees with the horizontal plane and is adjustable. In the case of slight inclination, due to the increased filtration time, the filtration effect of the aquaculture water pollution separation device can be effectively enhanced. This product has a simple structure, low cost, good dissolved oxygen effect, obvious water resource conservation, can easily separate and discharge most of the dirt in the water, improves the water quality and stability, and reduces the workload of cleaning the filtration device.

[0030] Appendix Figure 5 This is Embodiment 3 of the aquaculture water pollution separation device according to the present invention. The 4 water pollution separation barrels are symmetrically distributed along the center. In practical applications, the number and size of the water pollution separation barrels can be selected according to the required water body filtration volume. In other embodiments of the present invention, a flow sensor for controlling the first switch and the second switch is provided in the inner barrel. When the filtered water flow rate decreases, the first spray pipe is automatically controlled to close and the second spray pipe is opened to clean the filter net. A liquid level sensor for controlling the third switch is provided in the outer barrel. When the liquid level in the bottom of the outer barrel rises due to dirt blockage, the third spray pipe 9 is opened under the control of the third switch 10, and rotates and sprays above the sewage outlet 51 to wash the remaining dirt towards the sewage outlet.

[0031] It should be understood that the embodiments described herein should be considered only in a descriptive sense and not for the purpose of limitation. The description of the features or aspects within each embodiment should generally be considered applicable to other similar features or aspects in other embodiments. Although one or more embodiments have been described with reference to the accompanying drawings, those of ordinary skill in the art will understand that various changes in form and detail can be made therein without departing from the spirit and scope defined by the appended claims.
