[0042] A dewatering method of a sludge dewatering treatment device, and the specific dewatering treatment process is as follows:

[0043] S1, the sludge is put into the machine body 1, and the driving assembly 23 is started to crush the solid-liquid by rotating cutting structure and stirring structure, so that the solid-liquid is separated;

[0044] S2, then the filtered sewage carries some sludge to fall on the filter screen plate two 22, and the driving assembly 23 drives the lifting and swinging structure to drive the filter screen plate two 22 to carry out secondary filtration and solid-liquid separation;

[0046] The working principle and use process of the present application are as follows:

[0047] Sludge enters the machine body 1 through the feed hopper 11, and falls through the filter screen plate 1, and then the drive assembly 23 drives the rectangular groove wheel 24 to rotate. When the two symmetrical L-shaped tool holders 25 installed on the rectangular groove wheel 24 contact the slide plate rod 230, they will be squeezed to the L-shaped tool holder 25 and the spring 26, so that they can cut some plastic objects and solid sludge in the sludge. Through multiple rotations of the rectangular groove wheel 24, some plastic objects and solid sludge in the machine body 1 can contact the L-shaped tool holder 25 and be cut by the symmetrical blades on the L-shaped tool holder 25. The limiting plate 27 and the multiple fixed shaft rods 28 can position the L-shaped tool holder 25. When the rectangular groove wheel 24 rotates, it can also drive the U-shaped frame plate 232 and the multiple conical rod bars 233 in the U-shaped frame plate 232 to rotate synchronously, which is used to hit and stir the solid objects such as sludge and stones, so as to avoid damage and blockage of the device by large-particle hard solid impurities, and to achieve secondary multiple crushing, thereby improving the dewatering efficiency of the sludge. At the same time, the sewage and some sludge falling through the filter screen plate 1 will fall onto the filter screen plate 2. The convex disc 235 is driven by the drive assembly 23 to rotate, and the rotation of the convex disc 235 drives the ball shaft rod 236 and the universal joint 237 to rotate in one direction, thereby driving the multiple lifting rods 238 on the ball shaft rod 236 and the counterweight rope 239 to rotate in multiple directions. The filter screen plate 2 and the rubber ring plate 240 correspondingly rotate in multiple directions, and the high elasticity of the rubber ring plate 240 enables the filter screen plate 2 to rotate in multiple directions in the machine body 1, thereby separating the sludge and sewage in two stages. The separated water enters the water pipe 241, and the water flow drives the water rotating plate 243 and the screw rod 242 to rotate synchronously. The water rotating plate 243 in contact with the water can also purify it with activated carbon, thereby purifying some harmful chemical substances in the sewage. The rotating screw rod 242 drives the abutting plate 245 to move horizontally on the guide rod 244, thereby abutting and pressing one end of the filter screen plate 1. Since the other end of the filter screen plate 1 is hinged to the inner wall of the machine body 1, it can be inclined in the machine body 1. By manually opening the clamped plug 12 on the machine body 1, the sludge can be discharged. The sludge on the filter screen plate 2 can be automatically discharged by multiple rotations, thereby realizing the integrated discharge and purification.
