[0031] Furthermore, the cleaning component 2 includes a water guide head 22 for delivering water to each spray head 23. The lower part of the water guide head 22 passes through the left side of the outer shell 1 and is fixedly connected thereto. The left end of the water guide head 22 is fixedly connected to a connecting pipe 21 for connecting to a water pipe. The upper part of the water guide head 22 is fixedly connected to a plurality of spray heads 23 for spraying water onto the dewatering track 33 to flush and clean the dewatering track 33 and prevent impurities from clogging the gaps on the track.

[0032] Furthermore, the dewatering component 3 includes two conveying rollers 31 for driving the dewatering belt 33. The two conveying rollers 31 pass through the outer shell 1 and are rotatably connected thereto. A motor No. 1 is fixedly connected to the right front portion of the outer shell 1 for providing power to the component. The front end of the conveying roller 31 on the right side is fixedly connected to the output end of the motor No. 1 32. The two conveying rollers 31 are commonly connected to the dewatering belt 33 for sludge dewatering, which is provided with many fine dewatering pores. A plurality of supporting rollers 34 are commonly arranged between the two conveying rollers 31 for supporting and assisting the use of the extrusion component 5, which can rotate with the transmission of the dewatering belt 33. The supporting rollers 34 are rotatably connected to the outer shell 1.

[0033] like Figure 3As shown, the extrusion assembly 5 includes a No. 2 motor 51 for providing power for the assembly. The No. 2 motor 51 is fixedly connected to the rear side of the mounting plate 4. The output end of the No. 2 motor 51 is fixedly connected to a rotating shaft 52 for driving various components. The rotating shaft 52 penetrates the mounting plate 4 and is rotatably connected thereto. The front end of the rotating shaft 52 is fixedly connected to a circular plate 53 for connecting a lever 54. The front side of the circular plate 53 is fixedly connected to the lever 54, and its position deviates from the center of the circular plate 53. The outer wall of the lever 54 is slidably connected to a connecting ring 56. Used to cooperate and drive the connecting rod 57, the middle parts of the upper and lower sides of the connecting ring 56 are fixedly connected with connecting rods 57 for connecting various components.

[0034] Working principle: When in use, the sludge is fed into the device through the feed port 11, and the sludge will be sent to the upper part of the dewatering crawler 33 through the feed plate 12. The No. 1 motor 32 is turned on, and the conveying roller 31 connected thereto will rotate, and at the same time it will drive the dewatering crawler 33 connected thereto to transmit, thereby driving the conveying roller 31 on the other side to rotate through the dewatering crawler 33, and at the same time the supporting roller 34 will also be driven to rotate. When the dewatering crawler 33 is transmitted, it will drive the upper sludge to move. When the sludge is sent to the dewatering crawler 33, part of its water will directly flow to the lower part of the shell 1 through the pores on the dewatering crawler 33. With the drive of the dewatering crawler, the sludge will be transported to the lower part of the extrusion component 5. The No. 2 motor 51 is turned on, and the rotating shaft 52 connected thereto will rotate accordingly, thereby driving the circular plate 53 connected thereto to rotate, and the lever 54 connected to the circular plate 53 will also rotate accordingly, thereby driving the connecting ring 56 connected thereto to move, and the connecting ring 5 6 will move accordingly. Under the limit of the limit block 55, the connecting rod 57 will move up and down, thereby driving the pressing plate 58 connected to the lower connecting rod 57 to move up and down, repeatedly squeezing the sludge on the dewatering crawler 33 to assist its dehydration. The water in the sludge will pass through the crawler pores into the lower part of the shell 1 and then be discharged from the drain pipe 15. After repeated squeezing and dehydration by multiple squeezing components 5, the dehydrated sludge will be driven by the dewatering crawler 33 to continue to move. When it reaches the discharge port 16, since one end of the guide plate 14 is close to the dewatering crawler 33, it will shovel up the dewatered sludge and guide it to the outside of the device. The dewatering crawler 33 after dehydration will turn downward and continue to move. When it moves to the cleaning component 2, the spray head 23 will spray water to rinse the dewatering crawler 33 to prevent impurities from clogging the pores and affecting drainage. The cleaned crawler will come to the top again with the transmission to continue the sludge transportation and dehydration operations.
