The discharge port 3 can be used to discharge the raw materials after the reaction.

[0026] In a specific embodiment, as shown in the attached Figure 1 , 2As shown in , 3 and 4, a cleaning and drying structure is provided on the back of the kettle body 1, and the cleaning and drying structure includes a water tank 8, the water tank 8 is installed on the back of the kettle body 1, and a high-pressure pump 9 is provided on the surface of the water tank 8, and a delivery hose 10 is provided at the output end of the high-pressure pump 9, a hot air blower 11 is provided on one side of the water tank 8, and a hot air pipe 12 is provided at the air outlet end of the hot air blower 11, the stainless steel pipe 4 extends to the top of the kettle body 1, and a three-way pipe 13 is provided at the top of the stainless steel pipe 4, and a sealing bearing 14 is provided at the connection between the stainless steel pipe 4 and the kettle body 1 and the connection between the stainless steel pipe 4 and the three-way pipe 13, a gear ring 15 is provided on the outside of the stainless steel pipe 4, a gear plate 16 is provided on one side of the gear ring 15, a motor 17 is provided at the bottom of the gear plate 16, and an L-shaped connecting pipe 1 is provided on the other outer wall of the stainless steel pipe 4 8. A plurality of nozzles 19 are provided at one end of the L-shaped connecting pipe 18. The stainless steel pipe 4 is rotatably connected to the bottom end of the kettle body 1 and the three-way pipe 13 through a sealed bearing 14. Two support rods 20 are provided at the bottom of the three-way pipe 13, and the three-way pipe 13 is connected to the top of the kettle body 1 through the support rods 20. The input end of the high-pressure pump 9 extends to the inside of the water tank 8, and its output end is connected to the delivery hose 10. The air outlet end of the hot air blower 11 is connected to the hot air pipe 12. One end of the delivery hose 10 and the hot air pipe 12 are both connected to the top of the three-way pipe 13. Two solenoid valves 21 are provided on the outside of the three-way pipe 13. The output end of the motor 17 is coaxially connected to the gear plate 16, and the motor 17 is fixedly installed on the top of the kettle body 1. The gear plate 16 and the gear ring 15 are meshed with each other, and the gear ring 15 is fixedly installed on the outside of the stainless steel pipe 4.

[0027] Specifically, in this structure, when cleaning the inside of the kettle body 1, the solenoid valve 21 at the three-way pipe 13 connected to the delivery hose 10 can be opened. At this time, the high-pressure pump 9 delivers the water in the water tank 8 to the inside of the three-way pipe 13 through the delivery hose 10, and enters the inside of the stainless steel pipe 4. The stainless steel pipe 4 delivers the water to the inside of the L-shaped connecting pipe 18, and finally sprays it out through multiple nozzles 19. At this time, the motor 17 drives the gear plate 16 to rotate, and drives the gear ring 15 meshing with it to rotate through the gear plate 16. The gear ring 15 drives the stainless steel pipe 4 to rotate, so that the top of the stainless steel pipe 4 rotates at the bottom of the three-way pipe 13 through the sealed bearing 14, and the stainless steel pipe 4 rotates with the kettle body 1 through the sealed bearing 14, so as to achieve the effect of the stainless steel pipe 4 driving the L-shaped connecting pipe 18 to rotate, and drives the multiple nozzles 19 to evenly wash the inner wall of the kettle body 1;

[0028] After flushing, when it is necessary to dry the moisture attached to the inner wall of the kettle body 1, open the solenoid valve 21 at the three-way pipe 13 connected to the hot air pipe 12. At this time, the hot air blower 11 transports the hot air to the inside of the three-way pipe 13 through the hot air pipe 12, and finally transports it to the inside of the L-shaped connecting pipe 18 through the stainless steel pipe 4, so that the hot air dries the moisture attached to the inner wall of the kettle body 1 through multiple nozzles 19, thereby improving the reaction efficiency of the material.

[0029] In a specific embodiment, as shown in the attached Figure 2 , 6 As shown, a movable cavity is penetrated through the outer wall of the L-shaped plate 5, and the scraper strip 6 is slidably connected inside the movable cavity. A movable plate 22 is arranged inside the movable cavity at one end of the scraper strip 6, and a plurality of extrusion springs 23 are arranged at one end of the movable plate 22. The two ends of the plurality of extrusion springs 23 are respectively connected to the movable plate 22 and the inner wall of the movable cavity.

After the extrusion spring 23 is squeezed and reset, it can ensure that the scraper 6 always fits against the inner wall of the kettle body 1 to scrape, thereby avoiding the scraper 6 from being worn and affecting the cleaning of the inner wall of the kettle body 1.

[0031] In a specific embodiment, as shown in the attached Figure 3 , 5 As shown, a filter screen 24 is disposed inside the water tank 8 , and an activated carbon adsorption screen 25 is disposed at the bottom of the filter screen 24 .

[0033] Working principle of this utility model:

[0034] When the above structure is used, when reacting vanillin, the vanillin material is added into the kettle body 1 through the feeding port 2, and the motor 17 is used to drive the gear plate 16 to rotate, and the gear plate 16 drives the gear ring 15 meshing with it to rotate, and the gear ring 15 drives the stainless steel tube 4 to rotate, so that the top of the stainless steel tube 4 rotates at the bottom of the tee pipe 13 through the sealed bearing 14, and the stainless steel tube 4 rotates with the kettle body 1 through the sealed bearing 14;

[0035] The rotation of the stainless steel tube 4 drives the multiple stirring blades 7 to rotate, which can accelerate the reaction rate of vanillin, and can also drive the L-shaped plate 5 to rotate. During the rotation of the L-shaped plate 5, the scraper 6 is attached to the inner wall of the kettle body 1 and rotates, which can scrape off the raw materials attached to the inner wall of the kettle body 1, thereby reducing the waste of raw materials. Finally, the vanillin is discharged through the discharge port 3;

[0036] When the inside of the kettle body 1 needs to be cleaned, the solenoid valve 21 at the three-way pipe 13 connected to the delivery hose 10 can be opened, and the high-pressure pump 9 delivers the water in the water tank 8 to the inside of the three-way pipe 13 through the delivery hose 10, and enters the inside of the stainless steel pipe 4. The stainless steel pipe 4 delivers the water to the inside of the L-shaped connecting pipe 18, and the rotation of the stainless steel pipe 4 can drive the L-shaped connecting pipe 18 to rotate, and drive multiple nozzles 19 to evenly flush the inner wall of the kettle body 1, and cooperate with the use of the scraper 6 to improve the cleaning effect;

[0037] After the flushing is completed, when it is necessary to dry the moisture attached to the inner wall of the kettle body 1, the solenoid valve 21 at the three-way pipe 13 connected to the hot air pipe 12 is opened. At this time, the hot air blower 11 conveys the hot air to the inside of the three-way pipe 13 through the hot air pipe 12, and finally conveys it to the inside of the L-shaped connecting pipe 18 through the stainless steel pipe 4, so that the hot air dries the moisture attached to the inner wall of the kettle body 1 through the multiple nozzles 19, thereby improving the production efficiency of the material;

[0038] It is worth noting that the kettle body 1 in the present invention is a condensation reaction kettle, which can be used for the preparation reaction of vanillin. It is composed of an outer cylinder and an inner cylinder. There is a heating component between the inner cylinder and the outer cylinder, which is used to heat the vanillin raw material inside the inner cylinder. This structure is specifically the existing structure of the current condensation kettle and will not be explained in detail in the present invention.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
