[0022] As shown in Figure 4 The auxiliary assembly includes a support block 121, a protrusion 16 and a roller 17, the support block 121 is connected to the center point of the bottom end of the reaction bucket 2 by welding, the four protrusions 16 are distributed in an X shape and are connected to the top end of the support block 121 by welding, the roller 17 is rotatably connected to the lower part of the auger 12 and is located above the protrusion 16, the bottom end of the roller 17 is lower than the top end of the protrusion 16, to ensure that the two can contact each other, with the rotation of the roller 17, the bottom end of the roller 17 will periodically contact the top end of the plurality of protrusions 16 and be gradually extruded upward by the protrusions 16, the top end of the protrusion 16 is provided with a layer of buffer pad made of elastic material, such as silicone, which can reduce the impact force when contacting the roller 17, protect the contact surface and provide certain anti-skid function.

[0023] As shown in Figure 3As shown, it also includes a second connecting plate 7, a water pump 8, a water pipe 9 and a water outlet 10. The second connecting plate 7 is connected to the upper right side of the reaction barrel 2 by welding. The water pump 8 is connected to the second connecting plate 7 by bolts. The C-shaped water pipe 9 is connected to the water pump 8 by welding. The water inlet end of the water pipe 9 is communicated with the water outlet end of the water pump 8. The water outlet 10 is connected to the water pipe 9 by welding. The bottom end of the water outlet 10 extends to the inside of the reaction barrel 2 and is at the same level as the bottom end of the reaction barrel 2.

[0024] First, the operator pours the sludge to be treated into the reaction barrel 2 from the feed inlet 3. Then, the conditioner delivery pipe is connected to the water inlet end of the water pump 8. The water pump 8 is started to pump the conditioner into the water pipe 9. The conditioner is uniformly sprayed into the reaction barrel 2 through the multiple water outlets 10 to ensure that the conditioner is fully mixed with the sludge for reaction. After the appropriate amount of conditioner is sprayed into the reaction barrel 2, the water pump 8 is turned off, the connection between the conditioner delivery pipe and the water pump 8 is disconnected, and then the motor 11 is started. The output shaft drives the rotating shaft 15 to rotate at high speed, which in turn drives the auger 12 to rotate at high speed. The auger 12 transports the sludge at the lower part of the reaction barrel 2 upward to the upper part of the reaction barrel 2, realizing the circulating flow of the sludge. At the same time, the scraper 13 and the stirring rod 14 rotate at high speed with the auger 12. The scraper 13 scrapes the sludge attached to the inner wall of the reaction barrel 2 to prevent the sludge from accumulating. The stirring rod 14 stirs the sludge in the reaction barrel 2 to promote the full mixing of the sludge and the conditioner. When the auger 12 rotates at high speed, the roller 17 rotates at high speed with the auger 12. The roller 17 intermittently contacts the four protrusions 16 and is squeezed to drive the auger 12 to slide upward. When the roller 17 is out of the gap between the four protrusions 16, the auger 12 drives the roller 17 to slide downward and reset under the action of its own gravity. In this way, the auger 12 continuously drives the scraper 13 and the stirring rod 14 to move up and down, enhancing the mixing effect of the sludge and the conditioner and avoiding dead angles. When the reaction of the sludge and the conditioner is completed, the control valve 6 is opened to discharge the treated sludge through the discharge outlet 5. After the discharge is completed, the external pipeline is connected to the water inlet end of the water pump 8. The water pump 8 is restarted to send clean water into the water pipe 9, which is sprayed out of the water outlet 10 into the reaction barrel 2 to clean the reaction barrel 2. The dirty water after use is discharged from the discharge outlet 5. After cleaning is completed, the control valve 6 is closed to close the discharge outlet 5, the motor 11 and the water pump 8, and the external pipeline is disconnected from the water pump 8. The entire operation process is completed.

[0025] It is worth noting that by reasonably adjusting the positions of the protrusions 16 and the roller 17, they can effectively cooperate within the maximum range of the sliding of the auger 12, which not only improves the mixing efficiency of the equipment, but also prolongs the service life of the device and reduces the maintenance cost.

[0026] The above embodiment is only a preferred embodiment of the present application, and is not used to limit the scope of the present application, so that equivalent changes made according to the content of the present application claims should be included in the scope of the present application claims.
