[0036] As a technical optimization solution of the present invention, the provision of the connecting strip 9 can effectively increase the connection area between the support plate 41 and the sludge dewatering machine 1 , thereby improving the working efficiency of the support plate 41 .

[0037] refer to Figure 7 The sludge dewatering machine 1 is internally provided with a high-efficiency sludge dewatering system 10, and the high-efficiency sludge dewatering system 10 includes a sewage dewatering unit 11, and the output end of the sewage dewatering unit 11 is bidirectionally electrically connected to a starting power supply 12, and the output end of the starting power supply 12 is bidirectionally electrically connected to a filtrate collection and treatment unit 13, and the output end of the filtrate collection and treatment unit 13 is electrically connected to a diversified control unit 14.

[0039] refer to Figure 7 The output end of the diversified control unit 14 is electrically connected to the touch screen control module 141 , the output end of the diversified control unit 14 is electrically connected to the wireless control module 142 , and the output end of the diversified control unit 14 is electrically connected to the mobile phone control module 143 .

[0040] As a technical optimization solution of the present invention, the provision of the diversified control unit 14 can facilitate the user to control the operation of the sludge dewatering machine 1 using a variety of control methods, thereby improving the working efficiency of the sludge dewatering machine 1 .

[0041] The working principle and usage process of the present invention: When in use, the touch screen control module 141, the wireless control module 142 and the mobile phone control module 143 provide users with diversified control methods to flexibly adjust the working state of the sludge dewatering machine 1. At the beginning of the operation, the sludge is smoothly introduced into the sludge dewatering machine 1 through the feed hopper 2. Subsequently, the belt filter press 3 plays its key role, implements efficient filtration treatment on the sludge, and successfully squeezes out the water contained therein. On this basis, the sewage dewatering unit 11 inside the efficient sludge dewatering system 10 further deeply treats the sludge, significantly improves the dewatering efficiency, and ensures the treatment effect. When it is monitored that the sludge accumulation amount below the belt filter press 3 exceeds the preset threshold, the motor 43 starts immediately, and the output end of the motor 43 strongly drives the turntable 44 to rotate. The turntable 44 drives the transmission column 45 to slide smoothly in the moving groove inside the transmission plate 46 through a precisely designed transmission mechanism, thereby pushing the transmission plate 46 to move back and forth left and right. This series of The mechanical action is finally transmitted to the push plate 48 through the connecting rod 47, and the push plate 48 moves left and right, effectively pushing the accumulated sludge to one side, cleverly avoiding the occurrence of stacking. At the same time, the cylinder 582 is started synchronously, and its output end steadily pushes the connecting block 583 to move forward. The third gear 584 on the connecting block 583 then precisely meshes with the first gear 51 and the second gear 53, building a smooth power transmission chain. The first gear 51 drives the second gear 53 to start rotating through the transmission of the third gear 584. The second gear 53, with its threaded structure, tightly bites the screw 54, causing the screw 54 to rise steadily inside it. The rising action of the screw 54 directly drives the fixing frame 55 and the cleaning scraper 56 thereon to rise together. The top of the cleaning scraper 56 is tightly attached to the bottom of the belt filter press 3, efficiently cleaning up the adhered sludge. The cleaned sludge eventually falls into the collecting box 57, providing great convenience for subsequent processing.

[0042] To sum up: the sludge dewatering device and sludge dewatering system, by adding functionality that easily causes sludge accumulation, have the ability to automatically push the sludge to increase the working efficiency of the sludge dewatering device, prevent the occurrence of situations that easily cause sludge accumulation, and solve the problem that easily causes sludge accumulation.
