[0033] In this embodiment, combined with Figure 2 As shown, the stirring assembly includes a stirring shaft 220 rotatably disposed in the processing tank 100 , and stirring rods 221 are evenly distributed outside the stirring shaft 220 .

[0034] Specifically, the stirring shaft 220 is arranged at the center position of the treatment tank 100, wherein a reduction motor 130 for driving the stirring shaft 220 to rotate is arranged on the bottom wall of the treatment tank 100. The reduction motor 130 drives the stirring shaft 220 to drive the stirring rod 221 to rotate, so that it can better stir the wastewater in the treatment tank 100 and mix the activated sludge with the wastewater.

[0035] In order to install the reduction motor 130 , a support leg 104 for supporting the reduction motor 130 is arranged on the bottom wall of the processing tank 100 .

[0036] Specifically, in this embodiment, the upper end of the treatment tank 100 is opened, and a detachable tank cover is provided at the opening through bolts, thereby facilitating the installation of the stirring assembly and the aeration assembly in the treatment tank 100 .

[0037] Combination Figure 2-Figure 5 As shown, in this embodiment, the first driving member includes a first driving column 222 sleeved outside the stirring shaft 220; The aeration frame 200 includes a circular ring portion 301 sleeved outside the first driving column 222 and a straight rod portion 302 radially connected to the outside of the circular ring portion 301 along the treatment tank 100, and there are multiple straight rod portions 302. The inner wall of the treatment tank 100 is provided with a slide groove 311 along its height direction, and the slide groove 311 is provided with multiple corresponding straight rod portions 302. A slider is provided at the end of the straight rod portion 302 and slides in the slide groove 311. A cavity 401 is provided in the straight rod portion 302, and a driving block 420 is provided in the cavity 401 through a first spring 410. The aeration pipe 201 passes through the straight rod portion 302 and is connected to the corresponding driving block 420. The driving block 420 is provided with a first push rod 421 that passes through the annular portion 301. The first spring 410 is used to drive the first push rod 421 to abut against the outer wall of the first driving column 222. A groove 431 is provided on the outer wall of the first driving column 222, and a first guide surface is provided on the side wall of the groove 431. The rotation of the first driving column 222 is used to drive the first push rod 421 to slide into or out of the groove 431 along the first guide surface, thereby realizing the reciprocating movement of the aeration pipe 201.

[0038] In this embodiment, the first driving column 222 is fixed on the stirring shaft 220, that is, the rotation of the stirring shaft 220 can drive the first driving column 222 to rotate; wherein, through the cooperation of the slider and the slide groove 311, the aeration frame 200 is preferably lifted and installed in the treatment tank 100, and it cannot rotate circumferentially; Specifically, a limiting groove 402 connecting the cavity 401 is provided on the lower side of the straight rod portion 302 along the extension direction of the cavity 401, and the top of the aeration pipe 201 passes through the limiting groove 402 and is connected to the corresponding driving block 420. Therefore, through the above-mentioned structure, when the stirring shaft 220 drives the first driving column 222 to rotate, the first support rod 421 can slide into or out of the groove 431 along the first guide surface, thereby realizing the reciprocating movement of the aeration pipe 201 along the straight rod portion 302.

The inner wall of the lifting ring 610 is relatively provided with a sliding column 611 which slides in the sliding groove 501. The outer wall of the lifting ring 610 is provided with a push rod 230. The lower end of the push rod 230 is fixedly connected to the aeration frame 200. The stirring shaft 220 drives the second driving column 223 to rotate to drive the lifting ring 610 to rise and fall.

[0040] In this embodiment, combined with Figure 5As shown, in this embodiment, the second driving column 223 is fixed outside the stirring shaft 220, wherein the upper end of the top rod 230 is fixedly connected to the outer wall of the lifting ring 610, and the lower end is fixed to the corresponding straight rod portion 302, thereby making the lifting ring 610 unable to rotate circumferentially. At this time, the rotation of the stirring shaft 220 drives the second driving column 223 to rotate, so that the side wall of the sliding groove 501 squeezes the sliding column 611, thereby better realizing the lifting and lowering of the lifting ring 610, that is, the aeration frame 200 is lifted and lowered, and the lifting and lowering of the aeration pipe 201 is realized.

[0041] In this embodiment, the compressed air assembly includes an air supply cylinder 110, in which a piston plate 240 that can be raised and lowered is provided, on which a solenoid valve is provided, and on which a pull rod 241 is provided that passes through the air supply cylinder 110 and extends into the treatment tank 100. The lower end of the pull rod 241 is connected to the top rod 230, and the lifting ring 610 is lifted and lowered to drive the piston plate 240 to lift and lower, thereby pressing the air in the air supply cylinder 110 into the aeration pipe 201 for aeration.

The bottom of the air supply cylinder 110 is provided with an air supply hose (not shown in the figure) for connecting to the upper end of the aeration pipe 201, wherein the piston plate 240 moves downward in the air supply cylinder 110, at this time, the solenoid valve is closed, so that the piston plate 240 can press the gas in the air supply cylinder 110 into the aeration pipe 201 through the air supply hose to achieve aeration; when the piston plate 240 moves upward in the air supply cylinder 110, at this time, the solenoid valve is opened, so that the air supply cylinder 110 below the piston plate 240 is connected to the outside world, so that the piston plate 240 moves upward in the air supply cylinder 110, so that air enters the air supply cylinder 110 below the piston plate 240; Specifically, in order to facilitate the control of the opening and closing of the solenoid valve, in this embodiment, the diameter of the second driving column 223 is smaller than the diameter of the first driving column 222, thereby forming a step portion between the two. In actual use, the first trigger switch is installed at the step portion, and the upper end of the second driving column 223 extends outward to form a mounting portion 502, and the second trigger switch is installed at the mounting portion 502. Therefore, in this embodiment, when the pull rod 241 is connected to the top rod 230, the lifting ring 610 is circumferentially limited, and at the same time, the lifting and lowering of the lifting ring 610 can be driven The piston plate 240 is raised and lowered, so that in actual operation, when the lifting ring 610 rises to the highest point, the lifting ring 610 triggers the second trigger switch to close the solenoid valve. At this time, the piston plate 240 moves down with the lifting ring 610, and presses the air in the air supply cylinder 110 into the aeration pipe 201. When the lifting ring 610 moves down to the lowest point, the lifting ring 610 triggers the first switch to open the solenoid valve. At this time, the piston plate 240 moves up and resets with the lifting ring 610, thereby allowing the aeration shaft 220 to rotate to drive the aeration component to perform aeration work.
