[0049] Working principle and working process:

[0050] When the machine is working, the water inlet control valve of the water inlet pipe 64 and the water outlet control valve of the water outlet pipe 8 are opened first, then the driving motor 47 is started to drive the high-speed differential device 59 to rotate, and then the speed reducer motor 77 is started to drive the driving ring 36 to rotate. At this time, the water pump arranged outside the machine is started to input the solid-liquid material to be treated into the central shaft 52 from the water inlet pipe 64, and then the solid-liquid material enters the lower shell 75 of the rotating drum through the water inlet hole 71 arranged on the central shaft 52, is uniformly distributed to the periphery of the rotating drum by the water inlet distribution disc 69, and then is subjected to high-speed solid-liquid separation by the water inlet distribution disc 69 and the slag scraping driving disc 26 at the same time. The separated clean water flows upwards from the upper water hole one 22 in each separation piece 23 and the upper water hole two 25 in the slag scraping driving disc 26 to the upper center of the upper shell 15 of the rotating drum, and then flows into the central shaft 52 through the water outlet hole 19 arranged on the central shaft 52, and then is discharged outside the machine from the water outlet pipe 8.

[0051] Since the saucer-shaped rotating drum 21 has the advantages of large central volume and small peripheral volume when designed, the sludge separated in the rotating drum at high speed can be highly concentrated in the slag collecting groove 7 at the periphery. Then, under the action of the sealing groove plate 31 and the movable slag scraping plate 82 driven by the slag scraping driving disc 26, the sludge with greatly reduced water content is forced to be discharged from the slag outlet hole 86 through the slag outlet 93 at a close distance to the outside of the slag collecting groove 7 of the rotating drum.

[0052] The sludge discharged from the slag collecting groove 7 automatically falls into the slag holding groove 37 below by gravity, and then the sludge in the slag holding groove 37 is discharged from the slag discharge hopper 76 outside the machine by the driving ring 36 and the slag scraping plate 35 driven by the speed reducer motor 77, so as to complete the whole process of solid-liquid separation.
