[0029] Further, the cleaning rod 12 is composed of two parts, the upper part of the cleaning rod 12 abuts against the inside of the stirring bin 3, the lower part of the cleaning rod 12 abuts against the inner wall of the dredging bin 20, by setting the cleaning rod 12 abutting against the inner walls of the stirring bin 3 and the dredging bin 20, the dirt and residues on the inner walls of the stirring bin 3 and the dredging bin 20 can be effectively scraped off through the rotating movement during stirring, so as to keep the inner walls clean.

[0030] Working principle: when in use, the sewage in the water collecting tank 1 enters the minimum rotating pipe 11 through the drain pipe 22, and then flows into the interior of the stirring bin 3 and the first large bevel gear 4 through the minimum rotating pipe 11. When the motor 17 is started, it drives the small driving wheel 13 and the large driving wheel 14 to rotate through the driving shaft 15, and the large driving wheel 14 is in mesh with the first large bevel gear 4 and the second large bevel gear 10, thereby driving them to rotate in opposite directions. The rotation of the first large bevel gear 4 drives the maximum rotating pipe 5 and the cleaning rod 12 thereon to rotate, and the rotation of the second large bevel gear 10 drives the minimum rotating pipe 11 and the stirring blades inside the minimum rotating pipe 11 to rotate. The small driving wheel 13 is in mesh with the first small bevel gear 6 and the second small bevel gear 8, thereby driving them to rotate in opposite directions. The rotation of the first small bevel gear 6 drives the stirring blades on the larger rotating pipe 7 through the larger rotating pipe 7, and the rotation of the second small bevel gear 8 drives the stirring blades on the smaller rotating pipe 9 through the smaller rotating pipe 9. Thus, two groups of stirring blades rotating in different directions are formed in the stirring bin 3, which enhances the stirring effect and helps the mixing and dispersion of the suspended matter, dissolved matter and microorganisms in the sewage. The cleaning rod 12 on the maximum rotating pipe 5 is in abutment with the inner wall of the stirring bin 3 in the upper half and with the inner wall of the dredging bin 20 in the lower half during the rotation, thereby scraping off the dirt and residues on the inner wall through the rotating movement and playing a cleaning role. When it is necessary to reduce the stirring intensity or stop the cleaning function, the annular handle 19 can be slid towards the motor 17 through the control device, so that the movable pipe 18 is separated from the large driving wheel 14. At this time, the inner teeth of the large driving wheel 14 are not in mesh with the outer teeth of the movable pipe 18, so that the rotation of the driving shaft 15 will not drive the large driving wheel 14 and the bevel gears and rotating pipes associated therewith to rotate, thereby reducing the stirring intensity and stopping the cleaning function. When it is necessary to increase the stirring intensity and restore the cleaning function, the annular handle 19 can be pushed back to the original position, so that the movable pipe 18 is re-engaged with the large driving wheel 14. When the sludge deposition reaches a certain amount, the sewage in the stirring bin 3 and the dredging bin 20 is drained, the bottom cap 21 is opened, and the sludge can be discharged from the bottom of the dredging bin 20.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Accordingly, the present application is not to be limited to the embodiments shown herein but is to be accorded the broadest scope consistent with the principles and novel features disclosed herein.
