In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0027] like Figure 1-Figure 4 The sewage filtering device shown comprises: a sedimentation barrel, a guide tube 3, a driving mechanism, a first brush 4, a drainage pipe 9, a return pipe 10, a second brush 11 and a sewage collecting cup 12;

[0028] like Figure 1As shown, the sedimentation barrel includes a cylindrical barrel 1 and a conical barrel 2. The conical barrel 2 is larger at the top and smaller at the bottom. The upper end of the conical barrel 2 is coaxially connected to the lower end of the cylindrical barrel 1; the guide tube 3 is coaxially rotatable in the cylindrical barrel 1, and the bottom of the guide tube 3 is open; the driving mechanism is connected to the guide tube 3 to drive the guide tube 3 to rotate.

[0029] In a specific application, the driving mechanism includes a motor 7 and a reducer 8. The motor 7 is connected to the guide tube 3 through the reducer 8. The reducer 8 can be a gear reducer 8. For example, the reducer 8 includes a first bevel gear and a second bevel gear that mesh with each other. The first bevel gear is connected to the output shaft of the motor 7, and the second bevel gear is coaxially connected to the guide tube 3. Therefore, the motor 7 can drive the guide tube 3 to rotate through the reducer 8.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, the first brush 4 is fixed on the outer wall of the guide tube 3, and the first brush 4 is composed of a spiral brush 5 distributed in a spiral winding manner and a circumferential brush 6 distributed in a circumferential manner, wherein the circumferential brush 6 is multi-layered and arranged at intervals in the up and down directions, and the spiral brush 5 and the circumferential brush 6 are both in contact with the inner wall of the cylindrical barrel 1.

[0031] The drain pipe 9 and the return pipe 10 are both connected to the cylindrical barrel 1 , wherein the discharge end of the drain pipe 9 extends into the cylindrical barrel 1 and then extends upward from the bottom of the guide tube 3 into the guide tube 3 , and the return end of the return pipe 10 is higher than the first brush 4 .

[0032] The second brush 11 is fixedly connected to the guide tube 3 through the bracket 18, and the second brush 11 abuts against the inner wall of the conical barrel 2; the sewage collecting cup 12 is arranged at the bottom of the conical barrel 2, and a sewage discharge pipe 13 is arranged at the bottom of the sewage collecting cup 12, and a control valve 14 is arranged on the sewage discharge pipe 13.

[0033] Specifically, if Figure 1 As shown, when the device is in use, the sewage at the bottom of the aquaculture pond is discharged into the sedimentation barrel through the drain pipe 9. Since the drain pipe 9 extends upward into the guide tube 3, the sewage at the bottom of the aquaculture pond will continue to spray upward under inertia after being discharged from the drain pipe 9 to the sedimentation barrel, and then flow downward. In this process, large particles of impurities in the sewage will not continue to spray upward with the water flow under gravity, but will quickly fall and settle in the conical barrel 2 below, so that the preliminary separation of large particles of impurities and sewage can be achieved.

[0034] As the amount of sewage in the sedimentation tank increases and the water level rises, some fine impurities will flow along with the sewage around the bottom of the guide tube 3 and upward through the first brush 4. Since the first brush 4 includes a spiral brush 5 and a circular brush 6, these small impurities will be intercepted by the first brush 4, and the intercepted purified water will finally flow back to the breeding pond from the return pipe 10.

[0035] After a period of sedimentation and sewage discharge, for example, the sedimentation and sewage discharge can be set to occur every 4 hours, the driving mechanism drives the guide tube 3 to drive the first brush 4 to rotate a certain number of circles to fully scrub the inner circumferential wall of the cylindrical barrel 1.

[0036] The impurities brushed off and intercepted by the first brush 4 will gradually settle in the conical barrel 2 below. Since the second brush 11 is fixedly connected to the guide tube 3 through the bracket 18, the second brush 11 will also fully brush the inner wall of the conical barrel 2 during the circumferential rotation of the guide tube 3.

[0037] Since the conical barrel 2 is larger at the top and smaller at the bottom, and a dirt collecting cup 12 is provided at the bottom, impurities in the sewage will eventually settle in the dirt collecting cup 12, and the sewage can be discharged at a fixed time by opening the control valve 14. The control valve 14 can be a solenoid valve, which is easy to open and close automatically.

[0038] In a further configuration, a baffle 15 is provided in the guide tube 3. The baffle 15 is higher than the discharge end of the drain pipe 9. The baffle 15 is used to prevent the water flow from continuing to spray upward.

[0039] An overflow groove 16 with an L-shaped cross-section is coaxially fixed to the inner circumferential wall of the cylindrical barrel 1. The overflow groove 16 is located above the first brush 4 and separated from the guide tube 3. The return water end of the drain pipe 9 is connected to the overflow groove 16. Therefore, when the water level of the sewage intercepted by filtration is higher than the upper edge of the overflow groove 16, it will overflow into the overflow groove 16 and then be discharged from the drain pipe 9.

[0040] A nozzle 17 is provided inside the cylindrical barrel 1 . The nozzle 17 is located above the first brush 4 and sprays toward the first brush 4 , thereby cleaning the first brush 4 .

[0041] In summary, this device has the following characteristics:

[0042] 1. The sedimentation tank includes a cylindrical tank 1 and a conical tank 2 with a larger top and a smaller bottom, which is convenient for intercepting, filtering and sedimenting sewage impurities;

[0043] 2. A first brush 4 is provided in the cylindrical barrel 1, and a second brush 11 is provided in the conical barrel 2. The first brush 4 is composed of a spiral brush 5 which is spirally wound and distributed, and a circumferential brush 6 which is circumferentially distributed. Usually, the first brush 4 is in a static state. When sewage flows through the first brush 4, the first brush 4 will effectively intercept large particles and small particles of impurities in the sewage over a large area to achieve filtration and separation of impurities. After a period of sedimentation and sewage discharge, the driving mechanism can drive the guide cylinder to rotate. The first brush 4 and the second brush 11 can also brush the inner circumferential walls of the cylindrical barrel 1 and the conical barrel 2 during the rotation of the guide cylinder 3 to ensure the cleanliness of the device.

[0044] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
