[0012] Beneficial effects of the utility model:

[0013] 1. Compared with the traditional sludge dewatering device for environmental protection engineering, the sludge is usually dehydrated directly by mechanical pressure extrusion. The dehydration method has limitations, resulting in a low dehydration effect. By setting a mixing component to evenly stir the sludge and the conditioner, the particles in the sludge can be promoted to agglomerate into agglomerates, thereby making it easier to dehydrate the sludge. By setting a stirring box with a sewage inlet pipe and a feed pipe, the sludge and the conditioner can be contained. By setting a stirring module, the sludge and the conditioner can be stirred. By setting a driving motor, the first rotating shaft can be driven to rotate, so that the rotating shaft can drive the stirring rod to rotate, so that the stirring rod can stir and mix the sludge and the conditioner evenly. By opening a diversion hole on the surface of the stirring rod, part of the sludge and the conditioner can pass through, thereby reducing the rotational resistance. By setting the dehydration The component can dewater the sludge after stirring. By setting a discharge hopper with a control valve, the stirred sludge can be introduced into the dewatering cylinder through the feed hopper. By opening a through hole on the surface of the dewatering cylinder, the water in the sludge can flow through the through hole into the water tank below. By setting gauze on the outside of the dewatering cylinder, the sludge can be blocked to prevent small particles of sludge from falling. By setting a vibration motor, the dewatering cylinder can be driven to vibrate, so that the sludge can be dehydrated more thoroughly. By setting a conveying blade controlled by a rotating shaft inside the dewatering cylinder, the dehydrated sludge can be conveyed to the conveying component. By setting a first reduction motor, the second rotating shaft can be controlled to rotate, so that the second rotating shaft can drive the conveying blade to rotate slowly to drive the sludge to move forward slowly. The sludge can be conveyed forward and dehydrated during the conveying process.

[0014] 2. By setting a conveying component, the dehydrated sludge can be conveyed forward to the drying component for drying, and the dried sludge can be conveyed to the corresponding location after drying. By setting a second reduction motor, the conveyor belt can be controlled to rotate slowly, so that the conveyor belt drives the sludge to move slowly forward during the rotation process. When the conveyor belt drives the sludge to move slowly forward, it slowly passes under the drying component, so that the drying component can further dry and dehydrate the dehydrated sludge. By setting a drying component, the dehydrated sludge can be heated and dried. By setting a drying box, heat loss can be reduced. By setting a heating coil, heating can be performed. By setting a control module, the heating coil can be controlled to adjust the temperature and working state of the heating coil according to the actual drying situation. By setting a mixing component, the sludge and the conditioning agent are stirred and mixed to promote the sludge to agglomerate. Then, the mixed sludge is dehydrated by the dehydration component. Finally, the dehydrated sludge is dried by the drying component. Multiple dehydration can be achieved under the mutual cooperation of the mixing component, the dehydration component and the drying component, so that the dehydration effect is better than that of the traditional dehydration device.
