[0024] In specific implementation, when the present invention is used, after the raw materials are added to the interior of the reactor 1 through the feed port 2, the driving motor 502 in the motor compartment 501 is started, and the output end of the driving motor 502 drives the rotating column 503 to rotate forward, thereby driving the driving gear 504 to rotate forward, and then driving the driven gear 505 to reverse, and then the driven gear 505 reverses to drive the transmission column 506 to reverse, because the bottom end of the rotating column 503 is connected to the active rotating rod 507, and the bottom end of the transmission column 506 is connected to the driven rotating rod 509, at this time, the rotating column 503 rotates forward, driving the active rotating rod 507 to rotate forward, and the transmission column 506 reverses, driving the driven rotating rod 509 to reverse;

[0025] Then, the active rotating rod 507 rotates forward, driving the first stirring rod 508 to rotate forward, forming a forward stirring vortex in the reactor 1. The driven rotating rod 509 rotates reversely, driving the second stirring rod 510 to rotate reversely, forming two reverse stirring vortices in the reactor 1. Thus, three stirring vortices are formed in the reactor 1, forming a relative stirring mechanism, thereby quickly mixing the raw materials in the reactor 1, shortening the mixing time of the raw materials and improving work efficiency.

[0026] Since the bottom end of the active rotating rod 507 is connected to the transmission rod 511, when the active rotating rod 507 rotates, it will drive the transmission rod 511 to rotate together, thereby driving the side wall scraper 512 to rotate together. When the active rotating rod 507 rotates, the side wall scraper 512 will rub against the side wall of the reactor 1, thereby scraping off the material adhering to the side wall of the reactor 1, and since the top end of the side wall scraper 512 is connected to the support seat 513, the top end of the support seat 513 slides along the fixed ring 514 at this time, thereby auxiliary support for the rotation of the side wall scraper 512, so that the side wall scraper 512 can rotate stably, thereby scraping off the material adhering to the side wall of the reactor 1 while mixing the raw materials, preventing the material from remaining on the side wall of the reactor 1.

[0027] To sum up, when the present invention is used, the raw materials are first added to the reactor 1 through the feed port 2 for reaction. After the reaction is completed, the raw materials are transported to other reactors 1 through the delivery pipe 4, thereby realizing a continuous chemical reaction process and finally completing the synthesis of trifluoromethanesulfonyl chloride. In addition, each process is sampled and tested through the sampling port 3 to determine whether the raw material reaction of the process is qualified. This is the prior art and will not be elaborated on here. Three stirring vortices are formed in the reactor 1 through the mixing mechanism 5, and a relative stirring mechanism is formed, so that the raw materials in the reactor 1 are quickly mixed, shortening the mixing time of the raw materials and thereby improving work efficiency. While mixing the raw materials, the side wall scraper 512 will rub against the side wall of the reactor 1, thereby scraping off the material adhering to the side wall of the reactor 1 to prevent the material from remaining on the side wall of the reactor 1 and affecting subsequent use.
