In turn, the L-shaped rod 18 drives the filter frame 17 to rotate, so that the filter frame 17 flips to the outside of the filter box 3. The impurities inside are discharged by the operator knocking on the filter frame 17. It is convenient to use.

[0027] As a technical optimization of this utility model, the driving mechanism includes a drive motor 13 mounted on the upper surface of the mounting plate 5. The output end of the drive motor 13 is fixedly connected to a second rotating shaft 14 that is rotatably connected to the processing cylinder 2. A first pulley 15 is fixedly connected to the outer wall of the second rotating shaft 14, and a second pulley 16 is fixedly connected to the outer wall of the air pipe 8. The first pulley 15 and the second pulley 16 are connected by belt drive.

[0028] In this embodiment: the drive motor 13 is started, the drive motor 13 drives the second rotating shaft 14 to rotate, which in turn drives the first pulley 15 to rotate, the first pulley 15 further drives the second pulley 16 to rotate via the belt, which in turn drives the air pipe 8 to rotate, thereby driving the turntable 9 and the stirring assembly to rotate.

[0029] As a technical optimization of this utility model, the stirring assembly includes a first rotating shaft 11 fixedly connected to the upper end face of the turntable 9, and a plurality of circumferentially distributed stirring plates 12 are fixedly connected to the outer wall of the first rotating shaft 11.

[0030] In this embodiment: when the turntable 9 rotates, it drives the first rotating shaft 11 to rotate, which in turn drives multiple stirring plates 12 to rotate, stirring the wastewater and accelerating the wastewater reaction efficiency.

[0031] As a technical optimization of this utility model, the outer wall of the stirring plate 12 is provided with a plurality of uniformly distributed through holes.

[0032] In this embodiment, by opening multiple evenly distributed through holes on the outer wall of the stirring plate 12, turbulence can be generated during stirring, extending the residence time of bubbles and improving oxygen transport efficiency.

[0033] As a technical optimization of this utility model, the lower ends of the outer walls of both the processing cylinder 2 and the filter box 3 are connected to drain outlets with valves on the outer walls.

[0034] In this embodiment: by setting a drain outlet on the outer wall of the treatment cylinder 2, it is convenient to discharge wastewater into the filter box 3, and by setting a drain outlet on the outer wall of the filter box 3, it is convenient to discharge the filtered wastewater for recycling.

[0035] As a technical optimization of this utility model, the inner wall of the filter box 3 is fixedly connected to a support plate 21 located below the filter frame 17.

[0036] In this embodiment, the filter frame 17 is supported by a support plate 21 fixedly connected to the inner wall of the filter box 3.

[0037] As a technical optimization of this utility model, the outer wall of the filter box 3 is provided with a control panel, and the aerator 6, drive motor 13 and servo motor 19 are all electrically connected to the control panel.

[0038] In this embodiment, the aerator 6, drive motor 13 and servo motor 19 can be easily controlled to operate normally via the control panel.

[0039] The working principle and usage process of this utility model are as follows: First, wastewater and flocculant are introduced into the treatment cylinder 2. Then, the drive motor 13 is started, which drives the second rotating shaft 14 to rotate, thereby driving the first pulley 15 to rotate. The first pulley 15 further drives the second pulley 16 to rotate via a belt, which in turn drives the air pipe 8 to rotate, and then drives the turntable 9 and the stirring assembly to rotate. Next, the aerator 6 (an RG-50 type cyclone aerator) is started. The aerator 6 delivers oxygen to the inside of the turntable 9, which enters the treatment cylinder 2 through multiple air holes 10. The air is released as the turntable 9 rotates, allowing the gas to be evenly released into the wastewater. The stirring assembly rotates to stir the wastewater, and the air holes 10... The released bubbles are further broken down by the shearing action of the stirring plate 12, forming smaller bubbles, which greatly increases the gas-liquid contact area and improves the processing efficiency. After the reaction is completed, the drain port on the outer wall of the treatment cylinder 2 is opened to discharge the wastewater and impurities in the treatment cylinder 2 into the filter box 3. The impurities are filtered by the filter frame 17. After filtration, the drain port on the outer wall of the filter box 3 is opened to discharge the filtered wastewater for recycling. Then, the servo motor 19 is started, which drives the third rotating shaft 20 to rotate. This, in turn, drives the filter frame 17 to rotate through the L-shaped rod 18, causing the filter frame 17 to flip to the outside of the filter box 3. The impurities inside are discharged by the operator tapping the filter frame 17. It is convenient to use.
