[0026] Working principle of this utility model:

[0027] Refer to the instruction manual Figure 1-7, start the motor 3 and add cleaning liquid into the kettle body 1 through the water inlet pipe 4. The output end of the motor 3 drives the cross bar 21 on the stirring rod 19 to rotate, and the cross bar 21 drives the vertical rod 22 to rotate. The vertical rod 22 rotates the scraper pad 24 on the connecting rod 23 through the bolt 25 to clean the waste on the inner wall of the kettle body 1; when the scraper pad 24 is worn after use, the threaded rod 1 5 is rotated to move the threaded rod 1 5 downward on the kettle body 1, and then the motor 3 is started to make the cross bar 21 and the threaded rod 1 5 contact. At this time, the connecting rod 23 corresponds to the through groove 7, which is convenient for taking out the connecting rod 23 from the through groove 7. The motor 3 is turned off, and the threaded rod 27 is rotated to disengage from the connecting shaft 18, so that the threaded rod 27 ends the locking of the connecting shaft 18, and the connecting disk 10 is pulled outward to drive the connecting shaft 1 The connecting block 16 on 8 is disengaged from the through hole 17, releasing the locking of the blocking rod 6 by the connecting block 16 from moving up and down. At the same time, the connecting disk 10 stretches the spring 11, and then pulls the blocking rod 6 upward to disengage the through slot 7, opening the through slot 7 so that the through slot 7 is in an open state. Then, the connecting disk 10 is pressed to compress the spring 11, and the connecting disk 10 makes the connecting shaft 18 and the connecting block 16 pass through the through slot 7 and slide in the through hole 26. When the connecting block 16 passes through the through hole 26 and enters the avoidance groove 8, the avoidance groove 8 can allow the connecting shaft 18 with the connecting block 16 to rotate in the avoidance groove 8. By rotating the connecting disk 10, the connecting disk 10 drives the guide block 15 to drive the connecting plate 12 to rotate on the bearing 13 through the guide groove 14 on the connecting shaft 18, and at the same time, the spring 11 follows the rotation. , to avoid torsion damage to the spring 11 during rotation. When the connecting disk 10 is rotated at a suitable angle, the suitable angle is that the connecting block 16 can stagger the through hole 26 and loosen the connecting disk 10. At this time, under the action of the spring 11, since the shape of the through hole 26 is the same as the cross-sectional shape of the through hole 17 and the shape is not a perfect circle, the connecting block 16 can fit tightly with the connecting rod 23 after being rotated and loosened. Then, with the help of other tools, the bolt 25 is rotated through the through slot 7 to remove it from the threaded hole 20, so that the connecting rod 23 and the vertical rod 22 are separated. While removing the bolt 25, under the action of the spring 11, the connecting rod 23 is moved closer to the side of the through slot 7, so that the connecting rod 23 that drives the scraper pad 24 can move horizontally, and then the connecting disk is pulled outward. 10 makes the connecting block 16 on the connecting shaft 18 drive the connecting rod 23 to move outward, so that the connecting rod 23 with the scraper pad 24 is taken out of the through groove 7; during installation, the through hole 26 on the connecting rod 23 with the scraper pad 24 is sleeved on the connecting shaft 18, rotate the connecting plate 10, and then push the connecting rod 23 into the through groove 7 as close to the vertical rod 22 as possible, and then use the bolt 25 to connect the connecting rod 23 and the vertical rod 22, and then rotate the connecting plate 10 in the opposite direction to disengage the connecting shaft 18 from the through hole 26; then replace another one, the principle is the same as above; after the replacement is completed, pull the connecting plate 10 outward, and then insert the blocking rod 6 into the through groove 7, loosen the connecting plate 10 so that the connecting block 16 is located in the through hole 17, rotate the threaded rod 27 and the connecting shaft 18 to fit tightly, and complete the replacement of the scraper pad 24;The replacement method solves the problem that the scraper pad 24 and the brush in the reactor will continuously rub against the inner wall of the reactor during use, causing the scraper pad 24 and the brush to wear and affect the cleaning effect, and solves the problem that the scraper pad 24 is difficult to replace.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
