[0032] When the reactor 1 is in use, the motor 24 rotates and the first gear 23 and the second gear 25 are meshed, so that the stirring rod 3 rotates under the support of the support frame 2 to stir the material inside the reactor 1. After stirring, the material can flow out through the discharge pipe 27 by opening the material valve 28. Then, the movable rod 8 can be installed in the installation groove inside the connecting rod 6 and contact with the mounting block 7, so that the elastic brush 9 can contact the inner wall of the reactor 1. At this time, the reactor 1 is started, and the elastic brush 9 can rotate with the stirring rod 3 to quickly scrape and clean the solid material attached to the inner wall of the reactor 1. After cleaning, the elastic brush 9 can be removed from the connecting rod 6 through the feed pipe 26, which is convenient for quick cleaning or replacement of the elastic brush 9.

[0033] Example 2

[0034] Embodiment 2 is based on embodiment 1 in order to enable the elastic brush 9 and the connecting rod 6 to be quickly disassembled and assembled. Figure 2-3 As shown, a disassembly and assembly mechanism for limiting the position of the moving rod 8 is provided between the moving rod 8 and the mounting block 7, the disassembly and assembly mechanism includes a mounting ring 12, a mounting hole is opened on the rod wall of the moving rod 8, the mounting ring 12 is fixedly connected to the mounting block 7 and inserted into the mounting hole, a fixing block 13 is fixedly provided on the inner wall of the mounting ring 12, and fixing rods 14 are fixedly provided on both sides of the fixing block 13, a clamping block 15 is provided on the rod wall sliding sleeve of the fixing rod 14, the upper end of the clamping block 15 passes through the mounting ring 12 and is clamped on the outer upper end of the mounting hole, the upper ends of the two clamping blocks 15 away from each other are both inclined, the rod wall sleeve of the fixing rod 14 is provided with a second spring 16, and the two ends of the second spring 16 are respectively fixedly connected to the fixing block 13 and the clamping block 15.

[0035] When installing the elastic brush 9, the moving rod 8 is directly sleeved into the mounting ring 12 so that the mounting hole cooperates with the mounting ring 12. At this time, the inclined surfaces of the two clamping blocks 15 are in contact with the bottom of the mounting hole, so that the clamping blocks 15 are pushed and squeeze the second spring 16. When the moving rod 8 contacts the mounting block 7, the elastic force of the second spring 16 is restored, so that the clamping block 15 rebounds and is clamped on the outer upper end of the mounting hole to fix the position of the elastic brush 9. When the elastic brush 9 needs to be disassembled, the operator extends his hand into the reactor 1 through the feeding pipe 26 to press the two clamping blocks 15 and take out the moving rod 8.

[0036] Example 3

[0037] Example 3 is based on Example 1-2, in order to effectively clean all the inner walls of the reactor 3, as shown in FIG. Figure 1-2 and Figure 4 As shown, the elastic component includes a telescopic rod 10 and a first spring 11, the two ends of the telescopic rod 10 are fixedly connected to the mounting block 7 and the inner wall of the mounting groove respectively, the first spring 11 is sleeved on the outer side of the sleeve rod end of the telescopic rod 10, and the interior of the stirring rod 3 is provided with a synchronous driving mechanism for driving the two rotating rods 5 to rotate synchronously, and the synchronous driving mechanism includes two symmetrically arranged first worm gears 17, the upper ends of the side portions of the two mounting plates 4 are rotatably penetrated by a first worm 18, the first worm gear 17 is fixedly sleeved on the outer side of the rotating rod 5 and meshed with the first worm 18, the two first worm gears 18 are fixedly connected, a support plate 19 is fixedly provided on the upper end of the inner wall of the stirring rod 3, a second worm 20 is rotatably penetrated inside the support plate 19, the lower end of the second worm 20 is meshed with a second worm gear 21, the second worm gear 21 is fixedly sleeved on the outer side of the two first worm gears 18, the upper end of the second worm gear 20 passes through the stirring rod 3 and the reactor 1 and is fixedly provided with a rotating plate 22.

[0038] After the material inside the reactor 1 flows out, the rotating plate 22 can be rotated to rotate the second worm 20. At this time, the second worm 20 drives the second worm wheel 21 to rotate, and drives the two first worms 18 to rotate. Through the engagement of the first worm 18 and the first worm wheel 17, the two rotating rods 5 simultaneously drive the two connecting rods 6 to rotate. At this time, the installed elastic brush 9 can always contact with the inner wall of the reactor 1 under the push of the elastic force of the telescopic rod 10 and the first spring 11, so that when the stirring rod 3 rotates, the elastic brush 9 can fully clean the inner wall of the reactor 1.
