One end is connected with the circulation groove 6, and the rotating adjustment mechanism includes an adjusting tube 8, a clamping rod 9, an annular groove 10, a pressing rod 11, a pressing spring 12, a compensation spring 13 and a pressure plate 14. The clamping rod 9 extends into the adjusting tube 8, the annular groove 10 is arranged on the side of the clamping rod 9, the pressing rod 11 is horizontally slid through the side wall of the adjusting tube 8, the pressing spring 12 is installed between one end of the pressing rod 11 and the outer wall of the adjusting tube 8, the pressure plate 14 is rotatably installed on the side wall of the adjusting tube 8, and the compensation spring 13 is installed between the pressure plate 14 and the outer wall of the adjusting tube 8.

[0027] In this embodiment, after the wastewater in the sedimentation tank 1 is precipitated, the sediment at the bottom is gathered at the bottom of the tank. At this time, it is necessary to drain the water to the outside and enter the anti-blocking box 2 through the insertion pipe 7. The insertion pipe 7 is connected to the flow groove 6 inside the anti-blocking box 2 to provide a flow channel. As the water flows, the central axis 3 flows in the sedimentation tank, driving the connecting piece 4 and multiple groups of dredging leaves 5 thereon to rotate. The rotation of the dredging leaves 5 mechanically dredges the starch sediments and impurities entering the flow groove 6 to prevent the sediments from blocking the insertion pipe 7 and the flow groove 6.

At this time, the clamping rod 9 rotates in the adjusting tube 8, and the pressing rod 11 is pressed into the annular groove 10 of the clamping rod 9 through the lateral sliding action to achieve stable rotation of the clamping rod 9. By adjusting the displacement of the pressing rod 11, the degree of its pressing on the clamping rod 9 is adjusted, thereby controlling the tightness of the clamping rod 9, and then controlling the rotation degree of the central axis 3.

The clamping rod 9 is connected with the rotating rod 29. The connecting plate 15 is installed at the bottom end of the side wall of the adjusting tube 8. The connecting plate 15 is installed on one end face of the anti-blocking box 2. The oriented ring 18 is longitudinally slidably arranged on the outer wall of the adjusting tube 8. The inner wall of the oriented ring 18 presses against the pressure plate 14, so that the pressure plate 14 presses against the pressing rod 11 to press the clamping rod 9. The pressure degree of the pressing rod 11 is adjusted by controlling the pressure degree of the pressure plate 14. The threaded ring 16 is installed on the outer wall of the adjusting tube 8.

[0031] More specifically, wastewater enters the sedimentation tank 1 through the feeding pipe 30, and the stirring motor 21 in the tank drives the stirring blade 23 to rotate, stirring the wastewater evenly and accelerating the sinking of starch sediments. The sediments gather at the bottom under the action of gravity and are guided to the bottom of the sedimentation tank 1 by the ramp plate 24. After sedimentation, the water is introduced into the anti-blocking box 2 from the insertion pipe 7, and the central axis 3 inside the anti-blocking box 2 rotates, driving the connecting piece 4 and the dredging blade 5 to dredge the sediments in the flow groove 6 and the insertion pipe 7. The water passes through the flow groove 6 and the connecting pipe 26 and is finally discharged through the drainage assembly 27. The top cover 31 on the top of the anti-blocking box 2 can be used to check and clean the internal state.

At this time, it needs to be drained to the outside and enters the anti-blocking box 2 through the insertion pipe 7. The insertion pipe 7 is connected to the flow groove 6 inside the anti-blocking box 2 to provide a circulation channel. As the water flows, the central axis 3 flows in the sedimentation tank, driving the connecting piece 4 and multiple groups of dredging leaves 5 thereon to rotate. The rotation of the dredging leaves 5 mechanically dredges the starch sediments and impurities entering the flow groove 6 to prevent the sediments from clogging the insertion pipe 7 and the flow groove 6.

[0033] When it is necessary to rotate the adjustment mechanism, the rotating rod 29 is connected to the central shaft 3 through the chain transmission assembly 28. The rotation of the central shaft 3 drives the rotation of the rotating rod 29. At this time, the clamping rod 9 rotates in the adjustment tube 8, and the pressing rod 11 is pressed into the annular groove 10 of the clamping rod 9 through lateral sliding action to achieve stable rotation of the clamping rod 9. By adjusting the displacement of the pressing rod 11, the degree of pressing on the clamping rod 9 is adjusted, thereby controlling the tightness of the clamping rod 9, and then controlling the rotation degree of the central shaft 3.

[0034] Wastewater enters the sedimentation tank 1 through the feeding pipe 30, and the stirring motor 21 in the tank drives the stirring blade 23 to rotate, stirring the wastewater evenly and accelerating the sinking of starch sediments. The sediments gather at the bottom under the action of gravity and are guided to the bottom of the sedimentation tank 1 by the ramp plate 24. After sedimentation, the water is introduced into the anti-blocking box 2 from the insertion pipe 7. The central axis 3 inside the anti-blocking box 2 rotates, driving the connecting piece 4 and the dredging blade 5 to dredge the sediments in the flow groove 6 and the insertion pipe 7. The water passes through the flow groove 6 and the connecting pipe 26 and is finally discharged through the drainage assembly 27. The top cover 31 on the top of the anti-blocking box 2 can be used to check and clean the internal state. The rotation adjustment mechanism can control the water discharge speed and the rotation speed of the dredging blade 5 by adjusting the position and clamping degree of the clamping rod 9.
