DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4The utility model provides a technical solution: a stirring mechanism for a vertical reactor, comprising an outer shell 1, an inner cylinder 2, a top plate 3 and a stirring shaft 6, the inner cylinder 2 is installed inside the outer shell 1, the top plate 3 is fitted with the top of the outer shell 1, and the bottom end of the outer shell 1 is symmetrically distributed with hydraulic push rods 18, the output end of the hydraulic push rod 18 is connected to the bottom surface of the top plate 3, a fixing frame 4 is arranged at the bottom end of the top plate 3, one end of the stirring shaft 6 is fixedly connected to the fixing frame 4 and the middle end of the fixing frame 4, a stirring rod 7 and a scraping rod 8 are respectively arranged on the outer surface of the stirring shaft 6, a movable rod 10 is arranged at the front end of the scraping rod 8, a movable shaft 11 is arranged between the movable rod 10 and the scraping rod 8, and a torsion spring 12 is arranged on the outer surface of the movable shaft 11.

[0022] The top plate 3 and the fixing frame 4 are movably connected to the outer shell 1 and the inner tube 2 respectively, and a sealing gasket 5 is provided at the connecting end of the inner tube 2 and the fixing frame 4. The sealing gasket 5 is provided between the fixing frame 4 and the inner tube 2 to ensure the sealing of the connecting end, so as to ensure that the internal raw materials will not leak out during the stirring process.

[0023] The scraper rod 8 and the stirring rod 7 are symmetrically distributed on the outer surface of the stirring shaft 6, and the scraper rod 8 is movably connected to the inner surface of the inner cylinder 2, and a through cavity 9 is opened inside the scraper rod 8. The scraper rod 8 slides with the inner cylinder 2 in a rotating state. One end of the scraper rod 8 is bucket-shaped and has a through cavity 9 inside. The scraper rod 8 can scrape off the residual material on the inner wall of the rotating inner cylinder 2 and discharge it from the through cavity 9, which can prevent the residual material from continuously accumulating on the surface of the scraper rod 8 and affecting the cleaning effect.

[0024] The outer surface of one end of the movable rod 10 is rotatably connected to a movable connecting rod 13, and the other end of the movable connecting rod 13 is rotatably connected to a guide seat 14. The guide seat 14 slides with the stirring rod 7. The movable rod 10 rotates with the movable connecting rod 13. When the position of one end of the movable connecting rod 13 changes, the guide seat 14 can be pushed to slide along the stirring rod 7. The movable rod 10 moves through the resistance generated by contact with water, and the torsion spring 12 counteracts the resistance. Due to the unequal resistance and the elastic force of the torsion spring 12, the movable rod 10 can shake, and the stirring regularity is destroyed by the change in the angle of the movable rod 10, thereby improving the stirring effect.

[0025] Active connecting rods 15 are symmetrically distributed at the upper and lower ends of the guide seat 14. The active connecting rod 15 is rotatably connected to the guide seat 14. The guide seat 14 pushes one end of the active connecting rod 15 to move during horizontal movement, thereby linking the extension rod 17 at the other end of the active connecting rod 15 to slide inside the fixed slide seat 16, ensuring the stability of the structural transmission.

[0026] Fixed slides 16 are symmetrically distributed at the upper and lower ends of the stirring rod 7, and an extension rod 17 is slidably connected inside the fixed slide 16. One end of the extension rod 17 is rotatably coordinated with the movable connecting rod 15. The extension rod 17 is linked with the power generated by the raw material through the movable rod 10, so that it can reciprocate up and down inside the fixed slide 16, thereby further enhancing the effect of disrupting the regularity of raw material stirring.

[0027] Working principle: First, the inner cylinder 2 rotates under the driving mechanism. The driving mechanism includes a transmission structure composed of a motor and a gear at the bottom of the outer shell 1 and a rotating combination. When stirring, the raw material rolls inside the inner cylinder 2 under the influence of centrifugal force. The raw material contacts the movable rod 10 to generate resistance, and pushes the movable rod 10 to rotate with the movable shaft 11 as the center point. The torsion spring 12 is charged to resist the resistance, so that the movable rod 10 rotates slightly. At the same time, the angle between the movable rod 10 and the movable connecting rod 13 changes, and one end of the movable connecting rod 13 pushes the guide seat 14 along the movable shaft 11. Sliding along the outer surface of the guide seat 14, the movable connecting rod 15 on the outer surface of the guide seat 14 pushes the extension rod 17, so that the extension rod 17 is retracted and extended inside the fixed slide seat 16, thereby extending the length of the extension rod 17, increasing the contact area with the raw material, destroying the tension of the liquid raw material, and improving the stirring effect. When cleaning is required, the raw material inside the inner cylinder 2 continues to rotate after being discharged, and the hydraulic push rod 18 is started to lift the top plate 3 up and down. The scraper rod 8 slides along the inner wall of the inner cylinder 2, and can shovel out the residual material on the inner wall of the inner cylinder 2, thereby increasing the practicality of the overall structure.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
