DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See Figures 1 to 3 A reactor includes a tank body 100, a bracket 110 disposed on the top, a motor 111 mounted on the top of the bracket 110, and a connecting rod 112 connected to the output shaft of the motor 111. The connecting rod 112 extends into the interior of the tank body 100. The bottom of the tank body 100 is rotatably connected to a main shaft 200, and the connecting rod 112 is connected to the top of the main shaft 200, so that the motor 111 can drive the rotation of the main shaft 200. The main shaft 200 is connected to a stirring blade 300. The rotation of the main shaft 200 can drive the rotation of the stirring blade 300, thereby stirring the material in the tank body 100.

[0020] The main shaft 200 is provided with a mounting cavity 201 therein, and a telescopic hole 202 is provided on the side wall of the main shaft 200 . The stirring blade 300 is connected to the main shaft 200 via a support rod 210 that passes through the telescopic hole 202 and extends into the main shaft 200 . A first driving member 211 is provided at one end of the support rod 210 extending into the mounting cavity 201, and a first inclined surface 212 is provided on the side of the first driving member 211 facing the center of the main shaft 200. A second driving member 220 capable of moving in a vertical direction is provided at the center of the main shaft 200, and the second driving member 220 is provided with a second inclined surface 221 cooperating with the first driving member 211. The first inclined surface 212 and the second inclined surface 221 fit together, so that the second driving member 220 moving in the vertical direction can drive the first driving member 211 to move in the horizontal direction. At the same time, a limit plate 213 extending in the vertical direction is provided on the first driving member 211, and a first return spring 214 is provided between the limit plate 213 and the inner wall of the main shaft 200. When the second driving member 220 rises, it can push the first driving member 211 connected to the support rod 210 to move outward. When the second driving member 220 moves downward, the first return spring 214 pushes the second driving member 220 toward the center of the installation cavity 201, thereby driving the support rod 210 to retract. The side of the stirring blade 300 facing the inner wall of the tank body 100 is connected to a scraper 310. The stirring blade 300 can be driven closer to or away from the inner wall of the tank body 100 by the extension and contraction of the telescopic rod. When cleaning is required, the scraper 310 can contact the interior of the tank body 100 to scrape the material on the inner wall. When stirring, the scraper 310 scrapes the inner wall of the raw material tank body 100 to reduce the resistance during stirring.

[0021] The bottom of the mounting cavity 201 is provided with a mounting slot 230. The bottom of the second driving member 220 extends into the mounting slot 230. A second return spring 231 is disposed within the mounting slot 230. One end of the second return spring 231 abuts the second driving member 220, and the other end abuts the bottom of the mounting slot 230. This allows the second return spring 231 to push the second driving member 220 upward in the vertical direction. A drive rod 240 is disposed at the top of the second driving member 220. The drive rod 240 extends upward to the outside of the main shaft 200 and is connected to a movable lifting assembly 400. The lifting assembly 400 drives the second driving member 220 to rise and fall, thereby controlling the extension and retraction of the support rod 210. The lifting assembly 400 includes a lifting plate 410 located above the tank body 100. The lifting plate 410 is connected to a moving block 510, which is bolted to a screw rod 500. The moving block 510 is also connected to a guide rod 520. The screw rod 500 is mounted on the bracket 110. The rotation of the screw rod 500 can drive the lifting block to move up and down, thereby driving the lifting plate 410 to move up and down. The lifting plate 410 is connected to a lifting rod 420 that passes through the top of the tank body 100 and extends into the interior of the tank body 100. The end of the lifting rod 420 that extends into the interior of the tank body 100 is connected to a rotating disk 430. The rotating disk 430 is provided with a guide rail 431 on the side facing the drive rod 240. A ball groove 241 is provided at the top of the driving rod 240, and a rotatable ball 242 is installed in the ball groove 241. Under the push of the second return spring 231, the ball 242 is embedded in the guide rail 431. When the main shaft 200 rotates, the ball 242 moves along the guide roller.
