[0035] A method for using a sludge dewatering device comprises the following steps:

[0036] S1: By starting the hydraulic cylinder, the push plate is inserted into the first packaging assembly, at which time the four sets of spiral rods move away from each other, and the movable gear at the right end of the spiral rod is meshed with the first gear ring;

[0037] S2: by feeding the measured pre-treated sludge into the feeding trough of the first feeding and discharging mechanism and the interior of the second feeding and discharging mechanism, and then starting the first driving motor, so that the first driving motor drives the four sets of screw rods to rotate, so that the input sludge is transported to the interior by the four sets of screw rods, and the sludge is located between the four sets of screw rods;

[0038] S3: By starting the hydraulic cylinder again, the four sets of screw rods are driven to approach each other. At this time, the movable gears at the right ends of the four sets of screw rods are meshed with the second gear ring, so that the four sets of screw rods squeeze and transport the sludge to be transported. The water in the sludge falls to the lower end of the drain cylinder and is drained by the drain trough until the sludge is transported to the interior of the temporary storage cylinder.

[0039] S4: After the measured sludge is processed once, the first drive motor and the second drive motor are started to drive the two sets of lifting plates and the two sets of push plates on the same horizontal plane to move away from each other, and the sludge is transported to the outside of the four sets of spiral rods through the output pipe. The rotation of the spiral rods can drive the sludge into the interior of the drain cylinder;

[0040] S5: Start the hydraulic cylinder again to move the four sets of spiral rods away from each other again, so that the four sets of spiral rods cooperate with the extrusion winch plate to divert and squeeze the sludge on the outside until the escaped water is drained out through the drain trough, and the mud cake is discharged through the hollow surface at the lower end of the support tube and the lower end of the second feeding and discharging mechanism.

[0041] Compared with existing technologies:

[0042] Through the cooperation of the first feeding and discharging mechanism, the second feeding and discharging mechanism and the two sets of dewatering mechanisms, the sludge can enter the interior from both ends, and the sludge is squeezed, crushed and transported by the two sets of dewatering mechanisms, thereby increasing the amount of sludge to be treated, and further improving the working efficiency of sludge treatment;

[0043] Through the cooperation of two sets of dewatering mechanisms and transfer mechanisms, the accumulated sludge can be diverted, and then finely squeezed, crushed and transported through the dewatering mechanism, thereby reducing the squeezing distance of the sludge, increasing the dehydration degree of the sludge, making the discharged sludge drier, and preventing the occurrence of dry upper layer and wet lower layer.
