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

[0036] S1: By activating the hydraulic cylinder, the first push plate is inserted into the interior of the first packaging component. At this time, the four sets of spiral rods move away from each other, and the movable gear at the right end of the spiral rod engages with the first gear ring;

[0037] S2: The measured pre-treated sludge is fed into the feeding trough of the first feeding and discharging mechanism and the interior of the second feeding and discharging mechanism, and then the first driving motor is started to drive the four sets of screws to rotate, so that the input sludge is transported to the interior by the four sets of screws. At this time, the sludge is located between the four sets of screws.

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

[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 second 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 screw rods away from each other again, so that the four sets of screw rods cooperate with the extrusion winch to divert and squeeze the sludge on the outside until the separated 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 cylinder 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, so that the sludge is squeezed, crushed and transported by the two sets of dewatering mechanisms, thereby increasing the amount of sludge to be processed 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.

The two ends of the lifting plate 353 are threadedly connected to the two groups of first bidirectional screws 352. Therefore, the rotation of the first bidirectional screw 352 can drive the two groups of lifting plates 353 to move closer to or away from each other. The top two ends of the lifting plate 353 are rotatably connected to the first bidirectional screw 352. The second bidirectional screw 354 and the second driving motor 355 are installed on the front side of the right end of the top of the lifting plate 353. The second driving motor 355 is connected to the right side port of the second bidirectional screw 354 through the steering gear. The second driving motor 355 can drive the two sets of second bidirectional screws 354 to rotate. The two ends of the top of the lifting plate 353 are slidably connected to the second push plates 356. The bottom of the second push plates 356 is threadedly connected to the second bidirectional screw 354. The rotation of the second bidirectional screw 354 can drive the two sets of second push plates 356 to move closer to or away from each other. The right end of the rotating tube 322 is blocked by the left end of the lifting plate 353, so that the sludge discharged from the rotating tube 322 is separated up and down, and the sludge at the upper end falls to the surface of the upper lifting plate 353.The sludge at the lower end falls to the lower end of the temporary storage tube 351. The movement of the lifting plate 353 can transport the sludge. Combined with the movement of the second push plate 356, the sludge can be transported to the inside of the output pipe 342. The second push plate 356 can be set to a V shape to increase the transportation metering of the sludge.

[0071] The second feeding and discharging mechanism 4 is installed at the right end of another set of sludge dewatering mechanisms 2 . The structure of the second feeding and discharging mechanism 4 is the same as that of the first feeding and discharging mechanism 1 .

[0072] During specific use, those skilled in the art start the hydraulic cylinder 122 to insert the second push plate 132 into the interior of the first packaging component 14. At this time, the four groups of screw rods 23 move away from each other, and the movable gear 325 at the right end of the screw rod 23 engages with the first gear ring 321. The measured pretreated sludge is input into the feeding trough 123 of the first feeding and discharging mechanism 1 and the interior of the second feeding and discharging mechanism 4, and then the first drive motor 345 is started to drive the first drive motor 345 to rotate, so that the input sludge is transmitted to the interior by the four groups of screw rods 23. At this time, the sludge is located between the four groups of screw rods 23. By starting the hydraulic cylinder 122 again, the four groups of screw rods 23 are driven to move closer to each other. At this time, the movable gear 325 at the right end of the four groups of screw rods 23 engages with the second gear ring 323, so that the four groups of screw rods 23 squeeze and transport the transmitted sludge. The water in the sludge falls to the lower end of the drain barrel 211 and is drained out by the drain trough 212 until the sludge is transported to the interior of the temporary storage barrel 351. After the measured sludge is processed once, the first drive motor 345 and the second drive motor 355 are started to drive the two groups of lifting plates 353 and the two groups of second push plates 356 on the same horizontal plane to move away from each other, and the sludge is transported to the outside of the four groups of screw rods 23 through the output pipe 342. The rotation of the screw rods 23 can drive the sludge into the interior of the drain barrel 211, and the hydraulic cylinder 122 is started again to make the four groups of screw rods 23 move away from each other again, so that the four groups of screw rods 23 cooperate with the extrusion winch plate 222 to divert and squeeze the sludge on the outside until the water is drained out through the drain trough 212, so that the mud cake is discharged through the hollow surface at the lower end of the support barrel 111 and the lower end of the second feeding and discharging mechanism 4.
