[0029] like Figure 3-Figure 4 As shown, the stirring assembly 6 includes: a transmission rod 601, a plurality of stirring plates 602 arranged on the outer wall of the transmission rod 601, a scraper 603 arranged on the outer wall of the stirring plate 602, and a motor 604 arranged at one end of the transmission rod 601;
[0030] A reaction tank 8 is provided in the reactor 1, and a mounting hole 7 is provided through the circumferential inner wall of the reaction tank 8. One end of a transmission rod 601 is rotatably connected to the circumferential inner wall of the reaction tank 8, and the other end of the transmission rod 601 passes through the mounting hole 7 and is rotatably connected. A motor 604 is fixedly connected to one side of the reactor 1, and one end of the output shaft of the motor 604 is fixedly connected to the transmission rod 601. A plurality of stirring plates 602 are fixedly connected to the circumferential outer wall of the transmission rod 601, and a scraper 603 is fixedly connected to the circumferential outer wall of the stirring plate 602.
[0031] The circumferential outer wall of the scraper 603 fits tightly with the circumferential inner wall of the reaction tank 8, and a number of through grooves 607 are provided on one side of the stirring plates 602. A protective shell 605 is fixedly connected to one side of the reactor 1, and the motor 604 is located in the protective shell 605. The circumferential outer wall of the protective shell 605 is provided with penetrating heat dissipation holes 606.
[0032] It should be noted that the stirring assembly 6 drives the multiple stirring plates 602 to rotate through the transmission rod 601, thereby achieving efficient mixing of the solid residue in the reactor 1, ensuring that the residue can be evenly heated during the drying process, avoiding local overheating or uneven drying problems, and thus improving the drying efficiency. The scraper 603 fits tightly against the inner wall of the circumference of the reaction tank 8, effectively scraping off the residue attached to the wall, thereby preventing the accumulation of solid residue on the inner wall of the reaction tank 8; the through groove 607 opened on the stirring plate 602 helps to increase the fluidity of the liquid or gas during the stirring process, so that the heat and drying medium can be more evenly distributed in the residue; the motor 604 is placed in the protective shell 605, which effectively isolates the motor 604 from direct contact with the high temperature and humid environment inside the reactor 1; the heat dissipation hole 606 ensures that the heat of the motor 604 can be effectively dissipated during operation, avoiding the problem of overheating of the motor 604.
[0033] like Figure 1-Figure 2 As shown, the flow guide assembly 5 includes: a liquid collecting plate 501, a liquid partition plate 502 arranged on the upper surface of the liquid collecting plate 501, and a flow guide pipe 503 arranged on the outer wall of the reactor 1;

[0036] It should be noted that the guide assembly 5 realizes the effective collection and discharge of the liquid in the reaction tank 8 through the arrangement of the liquid collecting plate 501 and the liquid partition plate 502. The liquid collecting plate 501 is fixedly connected to the circumferential inner wall of the reaction tank 8 and can fully collect the condensed liquid generated by the drying process. The liquid partition plate 502 further blocks the collected liquid. The guide pipe 503 is located above the liquid collecting plate 501 and is connected to the reaction tank 8 to ensure that the collected liquid can be smoothly discharged to the outside of the reactor 1; the feed hopper 2 facilitates the continuous or intermittent addition of solid residue; the discharge pipe 3 facilitates the discharge of the residue after drying, simplifying the operation process.
[0037] When the present invention is used, the solid residue produced by pyrolysis is continuously or intermittently added to the reaction tank 8. After completion, the motor 604 is started, so that the output shaft of the motor 604 rotates to drive the transmission rod 601 to rotate, and the stirring plate 602 and the scraper 603 are driven to rotate through the transmission rod 601; the rotation of the stirring plate 602 realizes efficient mixing of the residue, ensuring that the residue can be evenly heated during the drying process; the scraper 603 fits tightly against the circumferential inner wall of the reaction tank 8, effectively scraping off the residue attached to the wall to prevent accumulation; at the same time, the drying unit 9 is turned on to dry the residue in the reaction tank 8; during the drying process, the condensed liquid generated in the reaction tank 8 will be collected by the liquid collecting plate 501 and blocked by the liquid partition plate 502; when the liquid on the liquid collecting plate 501 accumulates to a certain amount, the liquid is smoothly discharged to the outside of the reactor 1 through the guide pipe 503; when the drying process is completed, the motor 604 and the drying unit 9 are turned off; the discharge pipe 3 at the bottom of the reactor 1 is opened to discharge the dried residue.
