[0033] As Figure 2 and Figure 5 as well as Figure 6 shown, the stirring device 9 includes a second electric telescopic rod 91. The second electric telescopic rod 91 is fixedly connected to the side of the second mounting plate 3 close to the collection cylinder 61.

A third electric telescopic rod 94 is fixedly connected to the lower surface of the rectangular block 93. A plurality of first stirring rods 96 are fixedly connected to the surface of the third electric telescopic rod 94.

[0035] Working principle: When using the sludge dewatering device to dewater the sludge, first connect the sludge dewatering device to an external power source, then start the first motor 41 of the dewatering mechanism 4 through the control panel 7, the first motor 41 drives the auger 42 to rotate inside the filter cartridge 46, and at the same time, pour the sludge to be dehydrated into the filter cartridge 46 through the feed port 43, the rotation of the auger 42 drives the sludge to move inside the filter cartridge 46, and at the same time, the auger 42 and the filter cartridge 46 squeeze the sludge, and the squeezed water is guided by the water guide plate 47 in the sleeve 45 and discharged from the water outlet 44. When the pressure sensor 53 of the discharge mechanism 5 senses that the pressure reaches the set value, the control panel 7 receives the signal of the pressure sensor 53, controls the first electric telescopic rod 51 to contract, drives the blocking plate 52 to move away from the filter cartridge 46, and under the push of the auger 42, the sludge enters the collecting cylinder 61 of the collecting mechanism 6. At this time, the control panel 7 controls the second motor 63 to start, and the second motor 63 drives the collecting cylinder 61 to rotate through the rotating rod 62, so as to further dehydrate the sludge. The first mounting plate 2 and the second mounting plate 3 can be installed by setting the base 1. When using the sludge dewatering device to dewater the sludge, the sludge is first put into the feed port 82. At this time, the sludge pushes the arc block 88 to make the connecting block 87 slide on the inner wall of the square cylinder 81. The movement of the connecting block 87 makes the pull rod 84 slide on the inner wall of the fixed plate 83, so that the pull plate 86 moves away from the fixed plate 83. When the sludge enters the feed port 43, under the action of the elastic force of the spring 85, the arc block 88 moves away from the fixed plate 83 to close the feed port 82. By setting the blocking device 8, the feed port 43 can be closed after the sludge is put into the filter cartridge 46, so that in the process of using the sludge dewatering device to squeeze and dehydrate the sludge, the sludge accumulated due to squeezing can be avoided as much as possible from escaping from the sludge dewatering device through the feed port 43.

[0036] After the sludge enters the collection cylinder 61, the second electric telescopic rod 91 is activated through the control panel 7. The second electric telescopic rod 91 slides on the inner wall of the stabilizing plate 92. At the same time, the stabilizing telescopic plate 95 extends, pushing the rectangular block 93 to move closer to the collection cylinder 61. Then, the third electric telescopic rod 94 is activated, causing the connecting bar 97 to approach the collection cylinder 61. At this time, both the first stirring rod 96 and the second stirring rod 98 are inside the collection cylinder 61, so that when the collection cylinder 61 rotates, it can stir the sludge inside the collection cylinder 61. By setting the stirring device 9, it is avoided that the stirring rod rotates with the collection cylinder 61, resulting in a poor stirring effect on the sludge inside the collection cylinder 61, and as much as possible, it is ensured that the sludge will not become caked.
