A heating plate 23 is also fixed above the interior of the drying platform 21. The heating plate 23 is electrically connected to the solar top panel 11, the first solar side panel 12, and the second solar side panel 13. When the solar top panel 11, the first solar side panel 12, and the second solar side panel 13 are irradiated with sunlight, the solar top panel 11, the first solar side panel 12, and the second solar side panel 13 simultaneously generate electricity to supply power to the heating plate 23, so as to heat and dry the sludge on the heating plate 23.

[0029] A sliding collecting box 24 is also provided at one end below the drying table 21. The collecting box 24 is used to place the dried sludge residue scraped off the heating plate 23. Baffles 25 are fixedly provided at both ends above the drying table 21. Two symmetrically distributed third connecting blocks 26 are provided above the baffle 25 close to one end of the sludge box 1. The third connecting blocks 26 are rotatably connected to the bottom of the electric push rod 20.

[0033] When the lead screw slider 30 moves, it drives the scraper 32 to move synchronously, and the shafts at both ends of the scraper 32 extend into the lower sliding groove 341 in the side plate 34. When the lead screw slider 30 drives the scraper 32 to move to one side of the lead screw motor 28, the scraper 32 scrapes the dried sludge on the heating plate 23, so that the sludge falls into the collecting box 24 under the drying table 21. At this time, the shafts at both ends of the collecting box 24 slide in the lower sliding groove 341. When the lead screw slider 30 reaches the end close to the lead screw motor 28, the shafts at both ends of the scraper 32 push the block 345 upward, thereby entering the interior of the transfer groove 342, and the block 345 closes again.

The silt on the heating plate 23 is dried by the heating of the heating plate 23 and the irradiation of sunlight from above, thereby achieving double drying. After drying is completed, start the screw motor 28, and the screw motor 28 drives the scraper 32 to scrape the dried silt on the heating plate 23 to complete the silt drying operation.
