[0002] As we all know, the stacked screw sludge dewatering machine is a kind of environmental protection equipment used for sludge dewatering, which has been widely used in the field of environmental protection; the existing screw stacked sludge dewatering machine includes stacked screw body, sewage Box, sewage tank, power unit, screw shaft, back pressure plate and bracket, stacked screw body includes left connecting plate, right connecting plate, multiple fixed rings, multiple moving rings and multiple connecting rods, multiple fixed rings and multiple The moving rings are intersected and arranged to form a cylinder, and there are gaps between the fixed rings and the moving rings, and the fixed rings are fixed on the left connecting plate and the right connecting plate through a plurality of connecting rods. The left connecting plate is connected, the sewage discharge box is connected with the right connecting plate, the upper part of the sewage inlet box is provided with a sewage inlet, the lower part of the sewage discharge box is provided with a sewage discharge port, the power device is arranged on the side wall of the sewage discharge tank, and the right end of the screw shaft is connected with the power device. The left side is connected to the output end, the left side of the screw shaft passes through the interior of the sewage discharge box, multiple fixed rings and multiple moving rings, and the sewage inlet box in turn, and is rotatably connected with the left side wall of the sewage discharge box. The back pressure plate is located in the sewage discharge box inside, and the back pressure plate is fixed on the screw shaft; when using the existing stacked screw sludge dewatering machine, the sludge needs to be transported into the stacked screw from the sewage inlet, and the screw shaft is rotated by the power device, and the screw shaft and the Squeeze between the fixed ring and the moving ring to separate the liquid in the sludge and discharge it from the gap between the fixed ring and the moving ring. At the same time, the dewatered sludge is formed by the extrusion of the screw shaft and the back pressure plate. The mud cake is discharged through the sewage outlet; the existing screw-stack sludge dewatering machine is found in use, because the liquid discharged from the stacked screw still contains some pollutants, and it is easy to cause secondary pollution to the environment if it is directly discharged into the environment. Secondary pollution; at the same time, before the sludge is transported into the stacking screw, the sludge needs to be treated with flocculation. When the sludge after flocculation is not stirred evenly, it is easy to affect the dehydration effect of the sludge
