Wherein, the first ultrasonic transducer 33 is used for applying vibration to the inclined plate 31 in the sedimentation unit and is arranged outside the outermost inclined plate 31 in the sedimentation unit. A sedimentation channel is formed between two adjacent inclined plates 31, although the supporting columns 32 are arranged at the sedimentation channel, the size of the supporting columns 32 is small, and in addition, the cylindrical structure has negligible influence on sedimentation effect, and the cylindrical structure has very little influence on subsequent cleaning.

The sewage to be precipitated enters the thick slurry area 15 from the upper end of the vertical pipe 20 through the submersible sewage pump, the sewage in the thick slurry area 15 is gathered to a certain degree and then flows upwards to sequentially pass through the second through hole 121, the sedimentation channel in the sedimentation unit and the first through hole 111, and finally enters the clear liquid area 13; the sewage finishes the operations of sedimentation and clarification in the process of flowing upwards at the sedimentation channel, and the liquid finally entering the clear liquid zone 13 is clear liquid (the liquid with no solid suspended substances can be observed by naked eyes), and the clear liquid is finally discharged from the clear liquid outlet 16.

When the inclined plate sedimentation tank is cleaned and desilted, clear water is input from the upper end of the vertical pipe 20, after a sedimentation unit is submerged in water in the tank body 10, the first ultrasonic transducer 33 is started, the first ultrasonic transducer 33 can vibrate towards the inclined plate 31 on the outermost side in the sedimentation unit, and due to the existence of the support column 32 and the vertical arrangement between the support column 32 and the inclined plate 31, the inclined plate 31 on the outermost side in the sedimentation unit can drive the rest inclined plates 31 to vibrate together, and sludge attached to the surface of the inclined plate 31 can be cleaned under the action of high-frequency vibration generated by the first ultrasonic transducer 33; the ultrasonic vibration mode is adopted, the cleaning effect is high, the cleaning time is short, and the cleaning efficiency is high.

The number of the support columns 32 is too large, so that the sedimentation effect is easily hindered; if the number is too small, the distance between the two adjacent inclined plates 31 is easily affected during the ultrasonic vibration.

Furthermore, the sewage is convenient to discharge; the bottom of the tank body 10 is of an inverted cone structure.

Furthermore, in order to facilitate dredging; a plurality of second ultrasonic transducers 18 are mounted at the bottom of the tank body 10, and the second ultrasonic transducers 18 are arranged outside the tank body 10. The second ultrasonic transducer 18 vibrates against the bottom of the tank body 10, so that the settled thick slurry can be effectively prevented from being accumulated and scabbed at the bottom of the tank body 10.

Further, the clear liquid zone 13 is provided with a water passing plate 19 which is obliquely arranged, the lower end of the water passing plate 19 and the clear liquid outlet 16 are located on the same side, the lower end of the water passing plate 19 is hermetically connected with the inner wall of the tank body 10, and a gap is formed between the side of the tank body 10 far away from the clear liquid outlet 16 and the upper end of the water passing plate 19. The water passing plate 19 is provided with a mounting hole matched with the vertical pipe 20, the lower end of the vertical pipe 20 passes through the mounting hole, and the side wall of the vertical pipe 20 is connected with the mounting hole in a sealing manner.

Due to the water passing plate 19, in the clear liquid zone 13, no matter whether the clear liquid zone is close to the clear liquid outlet 16 or not, the liquid overflowing from the first through hole 111 firstly passes through the blocking of the water passing plate 19, then passes through the gap between the side of the tank body 10 far away from the clear liquid outlet 16 and the upper end of the water passing plate 19, and finally flows to the upper part of the water passing plate 19, and finally the clear liquid discharged from the clear liquid outlet 16 passes through the blocking and retaining of the water passing plate 19, so that even if the sludge at the settling unit accidentally upwells, the clear liquid discharged from the clear liquid outlet 16 can be effectively ensured. The water passing plate 19 is a flat plate which is arranged obliquely, and the oblique arrangement makes the lower surface of the water passing plate 19 not easy to deposit sludge.
