[0027] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. 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.

[0028] like Figure 1-Figure 3 As shown, one embodiment of the present invention provides a reactor for producing diosmin, comprising a reactor body 1, a stirring mechanism, a flow disturbance component, and a controller. A feed pipe 105 is installed on the top of the reactor body 1, and a discharge pipe 104 is installed on the bottom thereof; the stirring mechanism is installed on the reactor body 1 for stirring the reactants in the reactor body 1;

[0029] The spoiler assembly includes a first spoiler mechanism 3 and a second spoiler mechanism 4, which are symmetrically arranged inside the kettle body 1. The first spoiler mechanism 3 has a first air outlet and a second air outlet, and the second spoiler mechanism 4 has a third air outlet and a fourth air outlet. The first air outlet, the second air outlet, the third air outlet and the fourth air outlet are all close to the inner bottom wall of the kettle body 1; the airflow discharged from the first air outlet and the fourth air outlet flows around the first direction, and the airflow discharged from the second air outlet and the third air outlet flows around the second direction;

[0030] The spoiler assembly has a first state and a second state. When the spoiler assembly is in the first state, the first air outlet and the fourth air outlet in the spoiler assembly exhaust air; when the spoiler assembly is in the first state, the second air outlet and the third air outlet in the spoiler assembly exhaust air; the first direction and the second direction are two opposite directions; the controller is used to control the spoiler assembly to switch between the first state and the second state.

[0031] It should be noted that, in this embodiment, the first direction is a clockwise rotation direction around the axis of the kettle body 1 , and the second direction is a counterclockwise rotation direction around the axis of the kettle body 1 .

[0032] In this embodiment, when producing diosmin, hesperidin, iodine, and the reaction solvent, pyridine, are first introduced into the kettle 1 through the feed pipe 105 of the kettle 1 in order according to the reaction ratio. The kettle is then heated, and a stirring mechanism is activated to stir the hesperidin, iodine, and the reaction solvent, pyridine, in a first direction. Since hesperidin appears as white or pale needle-shaped crystals and iodine is a dark purple solid, hesperidin and iodine accumulate in large quantities near the bottom of the kettle in the early stages of the reaction. To ensure that hesperidin, iodine, and the reaction solvent, pyridine, are fully mixed, the controller controls the flow spoiler assembly to switch to a first state. The airflow discharged from the first and fourth air outlets of the flow spoiler assembly flows in the first direction, generating a vortex along the first direction. The hesperidin and iodine flow along with the vortex. The flow spoiler assembly cooperates with the stirring mechanism to stir, so that the hesperidin and iodine accumulated at the bottom of the reactor are fully mixed with the reaction solvent, pyridine, thereby improving the mixing efficiency of the hesperidin, iodine, and reaction solvent, pyridine.

[0033] After a period of reaction, the controller controls the spoiler assembly to switch to the second state, and the airflow discharged from the second air outlet and the third air outlet in the spoiler assembly flows in the second direction. Since the stirring mechanism is still stirring in the first direction at this time, a large amount of turbulence is generated in the reactor. Hesperidin and iodine flow to various positions of the reactor with the turbulent flow, so that hesperidin and iodine can be fully mixed with the reaction solvent pyridine, thereby improving the mixing efficiency of hesperidin, iodine and the reaction solvent pyridine.

[0034] It should be noted that the gas introduced into the kettle body 1 from the flow-turbulating assembly is an inert gas, such as argon or helium, which does not participate in the reaction process of producing diosmin.

[0035] As a preferred embodiment, Figure 2 and Figure 3 As shown, the first flow-disrupting mechanism 3 and the second flow-disrupting mechanism 4 have identical structures and are symmetrically mounted within the kettle body 1. Specifically, the first flow-disrupting mechanism 3 comprises a first main pipe 301, a first branch pipe 302, a first elbow pipe 303, a second elbow pipe 304, a first valve body 305, and a second valve body 306. The first main pipe 301 and the first branch pipe 302 are vertically mounted within the kettle body 1. The bottoms of the first main pipe 301 and the first branch pipe 302 extend into the kettle body 1 near its inner bottom wall, while the tops of the first main pipe 301 and the first branch pipe 302 pass through the kettle body 1. A circular hole is formed on the outer wall of the first main pipe 301 near its top. The top of the first branch pipe 302 is connected to the circular hole on the outer wall of the first main pipe 301. The bottom ends of the first main pipe 301 and the first branch pipe 302 are flush. One end of the first curved pipe 303 is sealed, and the other end has an opening forming a first air outlet. The bottom opening of the first main pipe 301 is connected to an opening in the side wall of the first curved pipe 303. One end of the second curved pipe 304 is sealed, and the other end has an opening forming a second air outlet. The bottom opening of the first branch pipe 302 is connected to an opening in the side wall of the second curved pipe 304. A second valve body 306 is mounted on the first branch pipe 302, and a first valve body 305 is mounted on the first main pipe 301, with the first valve body 305 lower than the connection between the first main pipe 301 and the first branch pipe 302. The first valve body 305 and the second valve body 306 are each connected to a controller signal. The airflow discharged through the first bend pipe 303 flows clockwise around the axis of the kettle body 1 , and the airflow discharged through the second bend pipe 304 flows counterclockwise around the axis of the kettle body 1 .

[0036] Furthermore, the second flow-disrupting mechanism 4 includes a second main pipe 401, a second branch pipe 402, a third curved pipe 403, a fourth curved pipe 404, a third valve body 405, and a fourth valve body 406. The second main pipe 401 and the second branch pipe 402 are vertically mounted on the kettle body 1, with the bottoms of the second main pipe 401 and the second branch pipe 402 extending into the kettle body 1 near its inner bottom wall, and the tops of the second main pipe 401 and the second branch pipe 402 passing through the kettle body 1. A circular hole is formed on the outer wall of the second main pipe 401 near its top. The top of the second branch pipe 402 is connected to the circular hole on the outer wall of the second main pipe 401. The bottom ends of the second main pipe 401 and the second branch pipe 402 are flush with each other. One end of the third curved pipe 403 is sealed, and the other end has an opening forming a third air outlet. The bottom opening of the second main pipe 401 is connected to an opening in the side wall of the third curved pipe 403. One end of the fourth curved pipe 404 is sealed, and the other end has an opening forming a fourth air outlet. The bottom opening of the second branch pipe 402 is connected to an opening in the side wall of the fourth curved pipe 404. A fourth valve body 406 is mounted on the second branch pipe 402, and a third valve body 405 is mounted on the second main pipe 401, with the third valve body 405 lower than the connection between the second main pipe 401 and the second branch pipe 402. The third valve body 405 and the fourth valve body 406 are each connected to a controller signal. The airflow discharged through the third bend pipe 403 flows counterclockwise around the axis of the kettle body 1 , and the airflow discharged through the fourth bend pipe 404 flows clockwise around the axis of the kettle body 1 .

[0037] During the initial reaction phase, the stirring mechanism rotates clockwise. The controller controls the first valve 305 on the first flow-disrupting mechanism 3 to open, the second valve 306 to remain closed, the third valve 405 on the second flow-disrupting mechanism 4 to remain closed, and the fourth valve 406 to open. The inert gas within the first main pipe 301 flows along the first main pipe 301 into the first curved pipe 303 and is then blown out clockwise along the first curved pipe 303. The inert gas within the second main pipe 401 enters the second branch pipe 402 and then flows from the second branch pipe 402 into the fourth curved pipe 404. The inert gas within the fourth curved pipe 404 is then blown out clockwise along the fourth curved pipe 404, thereby generating a clockwise swirling flow. Because the first curved pipe 303 and the fourth curved pipe 404 are both close to the inner bottom wall of the reactor, the hesperidin and iodine accumulated there flow along with the swirling flow, allowing the accumulated hesperidin and iodine to be fully mixed with the reaction solvent pyridine, thereby improving the mixing efficiency of the hesperidin, iodine, and the reaction solvent pyridine.

[0038] After a period of reaction, in order to further accelerate the mixing efficiency of hesperidin, iodine and the reaction solvent pyridine, the controller controls the second valve body 306 on the first flow-disturbing mechanism 3 to open, the first valve body 305 to switch to the closed state, the third valve body 405 to switch to the open state, and the fourth valve body 406 to switch to the closed state. The inert gas in the first main pipe 301 flows into the first branch pipe 302, and then flows into the second elbow pipe 304 along the first branch pipe 302. The inert gas blown out from the second elbow pipe 304 is blown in a counterclockwise direction. At the same time, the inert gas in the second main pipe 401 flows into the third curved pipe 403 along the second main pipe 401, and the inert gas blown out from the third curved pipe 403 flows in a counterclockwise direction. Since the stirring direction of the stirring mechanism at this time is still maintained in the clockwise direction, a large amount of turbulence is generated at the bottom position of the reactor. Hesperidin and iodine flow to various positions of the reactor along with the turbulent flow, so that the hesperidin and iodine can be fully mixed with the reaction solvent pyridine, thereby improving the mixing efficiency of the hesperidin, iodine and the reaction solvent pyridine.

[0039] As an optional embodiment, it further includes two inert gas storage tanks, two air pumps and two air pipes for conveying inert gas, wherein the air inlets of the two air pumps are respectively connected to the two inert gas storage tanks, the air outlets of the two air pumps are respectively connected to one end of the two air pipes, and the other ends of the two air pipes are respectively connected to the top openings of the first main pipe 301 and the second main pipe 401.

[0040] As a preferred embodiment, Figure 1 and Figure 2 As shown, the stirring mechanism includes a motor 2, a stirring shaft 5 and stirring blades 6. The stirring shaft 5 is vertically installed in the kettle body 1, the motor 2 is fixedly installed on the top outer wall of the kettle body 1, and the output end of the motor 2 is fixedly connected to the top of the stirring shaft 5. The stirring blades 6 are provided in multiple groups, and the multiple groups of stirring blades 6 are evenly arranged along the length direction of the stirring shaft 5. Each group of stirring blades 6 includes at least two stirring blades. Considering that if the stirring blades 6 are too close to the inner bottom wall of the kettle body 1, the inner bottom wall of the kettle body 1 may be damaged, therefore, the stirring blade 6 at the lowest position is set to be slightly higher than the first bend 303.

[0041] like Figure 1 and Figure 2 A jacket 101 is installed on the outer wall of the kettle body 1, and a heat preservation cavity is formed in the jacket 101. A water inlet 102 is provided on the outer wall of the jacket 101 near the top, and a water outlet 103 is provided on the outer wall near the bottom. By injecting hot water into the heat preservation cavity, a better heat preservation effect can be achieved.

[0042] In addition, commonly used heating elements such as heating wires and heating plates are provided on the inner wall of the kettle body 1, and a temperature controller is installed on the outer wall of the kettle body 1. The temperature controller is connected to the heating element signal, and the heating element is used to heat the reactants to provide heating conditions.
