The snail sludge dewatering machine belongs to the screw press dewatering machine, which can reduce the sedimentation tank and the sludge thickening tank, and save the construction cost of the sewage station. The stack screw sludge dewatering machine cleverly uses the multiple ring sheet active cleaning and filtering technology to replace the traditional filter screen. The self-cleaning and filtering technology ensures the continuous and stable mud-water separation effect of the stack screw sludge dewatering machine. The powerful extrusion caused by the change of screw diameter and pitch The pressure, as well as the small gap between the moving ring and the fixed ring, completes the squeezing and dehydration of the sludge. It is a new type of solid-liquid separation equipment.
The sludge that has been tempered in the sludge stabilization tank of the sludge dewatering machine is pumped to the "V"-shaped meter by the built-in sludge pump, and the measured sludge enters the flocculation reactor.
After the sludge enters the flocculation reactor, the second agent is injected again, and it is fully mixed and reacted to form a larger alum, which is then sent to the sludge filter body.
The sludge sent to the filter body enters the gravity thickening section, where a large amount of solids and water are quickly separated in the thickening section, and the sludge dewatering machine pushes the sludge to the dewatering section.
In the dewatering section of the snail sludge dewatering machine, the relative movement of the movable and fixed pieces and the pressure in the filter chamber are strengthened from time to time, resulting in the dewatering, and the dried cake is discharged out of the machine. In addition, under the effect of high internal pressure in the filter body, a small amount of SS on the surface of the filter cartridge sometimes overflows with the filtrate. Therefore, the upper part of the filter body is equipped with a spray nozzle to keep it clean with a small amount of spray water. The sprayed sewage is returned to the sludge stabilization tank.
