In addition, when the advancing roller 34 rotates to disperse sludge, the movable shaft 35 drives the connecting plate 41 to move, the connecting plate 41 drives the piston shaft 42 to move, so that the piston shaft 42 moves in the piston cylinder 43, the piston shaft 42 initially drives the sealing ring 45 to move through a damping relation with the damping ball 48, the sealing ring 45 is not extruded to move with the piston cylinder 43 when moving to a certain position, at the moment, the sealing ring 45 is communicated with the discharge pipe 46 to cancel sealing connection, and meanwhile, the sealing ring 45 is not communicated with the feed pipe 47 to start sealing connection, so that additives in the piston cylinder 43 are added into the processing tank 2 through the discharge pipe 46 in the moving process of the piston shaft 42, thereby being capable of preprocessing the sludge in cooperation with the advancing roller 34, improving the dewatering effect of the sludge, and the additives are polymerization agents or chemicals; when the movable shaft 35 moves reversely, the piston shaft 42 drives the closed ring 45 to move reversely, so that the closed ring 45 closes the discharging pipe 46 and is communicated with the feeding pipe 47, and therefore, additives in the storage tank 44 can be extracted into the piston cylinder 43 through the feeding pipe 47, the automatic feeding effect is achieved, the automation is high, the workload is reduced, and the working efficiency is improved;
In addition, the moving distance of the piston shaft 42 can be automatically adjusted according to the moving distance of the moving shaft 35, and the adding amount of the additive is further controlled, so that the adding amount of the additive required can be automatically calculated according to the sludge amount, the automatic adding is high, the additive and the sludge can be uniformly mixed by being matched with the dispersion of the advancing roller 34, and the dewatering effect of the sludge is further improved;
In addition, after the sludge amount in the processing tank 2 is fixed, the feed port on the processing tank 2 is closed, at this time, the closing shaft 36 moves along with the moving shaft 35 to close the processing tank 2, at this time, the air extractor 51 is started, the air extractor 51 extracts air from the interior of the processing tank 2 through the air extraction pipe 52 at the air extraction end, the interior of the processing tank 2 is enabled to approach to the vacuum environment, the pressure in the processing tank 2 is changed, the low-pressure environment in the processing tank 2 is matched with the mechanical pressure of the push ring 37, the sludge dewatering effect can be greatly improved through double matching, in addition, the moving shaft 35 drives the closing shaft 36 to move reversely, when the closing shaft 36 moves reversely to a certain position, namely, the closing connection relation with the processing tank 2 is canceled, at this time, the sludge dewatering is completed, and meanwhile, the air extractor 51 can be closed, so that the working time can be automatically adjusted according to the sludge amount, the working load and the resource loss of the air extractor 51 can be reduced, after the closing shaft 36 and the processing tank 2 are canceled, the sealing relation of the sludge is discharged from the interior of the processing tank 2, in addition, the sludge can be discharged after the valve is controlled, and the bottom of the processing tank 2 is controlled.
