[0049] Working principle of the present invention: When in use, the microwave waveguide 201 is electrically connected to an external microwave generator. First, the motor 501 is started to drive the rotating rod 5, the unloading spiral blade 502, the inner cone 4 and the discharge barrel 401 to rotate synchronously. The sludge is transported to the inner cone 4 by the unloading spiral blade 502 through the feeding barrel 303. The inner cone 4 rotates at a high speed. Under the action of centrifugal force, the water is thrown to the outer cone 3 to separate and pre-treat the excess water in the sludge. Then, through the cooperation of the rotating ring 203, the inner gear ring 204, the discharge barrel 401 and the outer gear ring 402, the scraper plate 6 is driven to rotate in the opposite direction to scrape the inner wall of the inner cone 4. First, it prevents the accumulation of residual sludge from causing blockage and ensures smooth and rapid unloading of the sludge. Second, it assists the preliminary dehydration of the sludge through mechanical scraping. At this time, the material leveling plate 7 can evenly distribute the sludge entering the drying box 2 during the rotation process. The microwave waveguide 201 emits microwaves toward the inside of the drying box 2, and the microwaves can penetrate The microwaves 704 and 705 are used to transfer the sludge to the sludge, and the sludge is dried.
