[0024] See also Figure 2 In order to quickly clean the solids in the sedimentation tank 1, the output shaft of the motor 81 is transmission-connected to the upper end of the rotating rod 82, and the outer wall of the rotating rod 82 is fixedly connected to one end of the connecting rod 83. The filter screen 87 is conical in shape and matches the conical ring 84.

[0025] See also Figure 3 In order to quickly adjust the height position of the overflow pipe 98, the adjusting mechanism 9 includes a fixing frame 91, the left side of the fixing frame 91 is fixedly connected to the right side of the sedimentation barrel 1, a threaded barrel 92 is provided in the middle part of the fixing frame 91, a screw 93 is provided on the inner wall of the threaded barrel 92, a turntable 94 is fixedly connected to the upper end of the screw 93, a connecting plate 95 is rotatably connected to the lower end of the screw 93, guide rods 96 are fixedly connected to both sides of the upper end of the connecting plate 95, a fixing sleeve 97 is fixedly connected to the lower end of the connecting plate 95, an overflow pipe 98 is inserted into the inner wall of the fixing sleeve 97, the inner wall of the fixing frame 91 is fixedly connected to the outer wall of the threaded barrel 92, the inner wall of the threaded barrel 92 is threadedly connected to the outer wall of the screw 93, and the input end of the overflow pipe 98 extends to the interior of the sedimentation barrel 1.

[0026] Working principle: First, the sewage is passed through the cone-shaped interior of the sedimentation barrel 1, and then the sewage enters the interior of the sedimentation barrel 1 through the water inlet pipe 4. After the sedimentation is completed, the water can be discharged by controlling the opening and closing of the electromagnetic valve inside the sewage pipe 3. The electric telescopic rod 6 is provided with four, which can simultaneously push the mounting plate 7 to move up or down, and increase the stability of the motor 81 when in use. At this time, the output shaft of the motor 81 drives the rotating rod 82 and the connecting rod 83 to drive the conical ring 84 to rotate, and under the action of the electric telescopic rod 6, it drives it to move downward, and the outer diameter of the piston ring 85 is the same as that of the sedimentation barrel 1. The inner diameter of the piston ring 85 is the same as the outer diameter of the tapered ring 84, which can provide a more sealed effect inside the sedimentation barrel 1 until the filter screen 87 enters the interior of the sedimentation barrel 1. At this time, the nylon wire 86 arranged on the outer wall of the tapered ring 84 fits with the bottom wall of the inner cavity of the sedimentation barrel 1, and the sludge deposited on the inside of the sedimentation barrel 1 can be brushed and swept. The brushed sludge is finally discharged through the sewage pipe 3, further improving the cleanliness of the sludge cleaning. The water body is discharged through the sewage pipe 3. The filter screen 87 can prevent the precipitated sludge and impurities from being discharged along with the water body while allowing the water body to pass through.

[0027] Then, after adding sewage into the sedimentation barrel 1, the staff turns the turntable 94 to rotate, so that the screw 93 is screwed onto the threaded barrel 92, and the screw 93 drives the connecting plate 95 to move up or down. Then, by providing two guide rods 96, it slides on the fixed frame 91, and the movement of the connecting plate 95 drives the movement of the fixed sleeve 97 and the overflow pipe 98, so as to adjust the height of the overflow pipe 98, thereby determining the height of the sewage inside the sedimentation barrel 1, and then the precipitated water overflows through the overflow pipe 98. The above is the working process of the entire device, and the contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
