At this time, the servo motor is turned on, and the servo motor drives the rotating shaft to rotate, and the rotating shaft drives the stirring blades to stir the sewage, thereby accelerating the reaction of the catalyst and the sewage. At the same time, the rotating shaft drives the support rod, the pad and the scraper to rotate, and the scraper scrapes the dirty oil above the sewage. When the scraper moves to the position of the oil guide frame, the scraper rotates relative to the support rod, and the dirty oil on the scraper enters the oil guide frame through the guide member, and is finally discharged from the sewage treatment barrel through the oil drain pipe. After the sewage is treated, the water in the sewage treatment barrel is discharged through the outlet pipe. The stirring device achieves the effect of facilitating the staff to stir the sewage and the catalyst in the sewage treatment barrel, thereby accelerating the reaction of the catalyst and sewage, and facilitating the treatment of the dirty oil in the sewage, thereby improving the practicality of the sewage treatment barrel.

[0022] When sewage needs to be treated, the staff first sends the sewage into the sewage treatment barrel through the water inlet pipe, and then sends the catalyst into the sewage treatment barrel through the drug inlet pipe. At this time, the servo motor is turned on, and the servo motor drives the shaft to rotate.

[0034] Working principle: When sewage needs to be treated, the staff first sends the sewage into the sewage treatment barrel 1 through the water inlet pipe 2, and then sends the catalyst into the sewage treatment barrel 1 through the drug inlet pipe 4. At this time, the servo motor 61 is turned on, and the servo motor 61 drives the rotating shaft 62 to rotate. The rotating shaft 62 drives the stirring blade 63 to stir the sewage to accelerate the reaction between the catalyst and the sewage. At the same time, the rotating shaft 62 drives the support rod 64, the pad 65 and the scraper 67 to rotate. The scraper 67 scrapes the dirty oil above the sewage. When the scraper 67 moves to the position of the oil guide frame 69, the scraper 67 rotates relative to the support rod 64, and the coil spring 610 on the pad 65 is deformed.

When the scraper 67 moves over the oil guide frame 69, the scraper 67 moves back to its original position under the action of the restoring elastic force of the coil spring 610, which facilitates the reciprocating movement of the scraper 67. After the sewage is treated, the water in the sewage treatment barrel 1 is discharged through the outlet pipe 3.

[0035] Before using the sewage treatment barrel 1, the staff first places the collection frame 72 into the limiting groove 73 of the fixed plate 71 through the handle 74. When the dirty oil is discharged from the oil drain pipe 5, the dirty oil enters the collection frame 72 of the fixed plate 71, thereby achieving the effect of collecting the dirty oil. The effect of collecting the dirty oil is achieved through the auxiliary device 7, which makes it convenient for the staff to uniformly treat the dirty oil.
