[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0019] See also Figures 1 to 4 A novel catalyst reaction system for di-n-butyrate comprises a reactor 1, a feed pipe 2 is connected to the top of the reactor 1, a cylinder 3 is connected to the top of the feed pipe 2, a discharge pipe 4 is connected to the top of the cylinder 3, a rotating rod 5 is inserted through the cylinder 3 and connected to the cylinder 3, a motor 6 is fixedly connected to the bottom of the cylinder 3, an output shaft of the motor 6 is fixedly connected to the rotating rod 5, the upper half of the rotating rod 5 is set in the air, a baffle 7 is provided on the inner wall of the cylinder 3, the baffle 7 is sleeved on the rotating rod 5, and a ring-shaped switch mechanism 8 is provided on the baffle 7. Two annular grooves 9 are provided on the inner wall of the cylinder 3, and heating rings 10 are rotatably connected to the inner walls of the two annular grooves 9. The two heating rings 10 are both annular in shape. 10 are interspersed with annular stirring tubes 11, one end of the stirring tube 11 is connected to the rotating rod 5, the right side of the cylinder 3 is fixedly connected to a collecting box 12, the left side of the collecting box 12 is connected to the two annular grooves 9 through two guide tubes, the top of the collecting box 12 is connected to a return pipe 13, a hot air blower 14 is installed on the return pipe 13, the top of the return pipe 13 is connected to a connecting tube 15, the bottom of the connecting tube 15 is sleeved on the rotating rod 5 and rotatably connected thereto; the switching mechanism 8 includes a discharge hole 801, the discharge hole 801 is opened on the baffle 7, the bottom of the baffle 7 is fixedly connected to an electric push rod 802, one end of the electric push rod 802 is fixedly connected to a sealing block 803, and the top of the sealing block 803 is in contact with the baffle 7.

[0020] In the present invention, when processing and producing di-n-butyrate, the reactants are first added into the cylinder 3 from the discharge pipe 4, and the reactants will first fall on the baffle 7. At this time, the sealing block 803 will seal the discharge hole 801, so that the reactants can stay on the top of the baffle 7. At this time, the user turns on the hot air blower 14, and the hot air blower 14 will extract the air inside the collection box 12 and heat it to a specified temperature, and then send it into the rotating rod 5 from the return pipe 13 and the connecting tube 15. Then the hot air will flow from the stirring tube 11 into the annular cavity formed by the annular groove 9 and the heating ring 10, and the hot air will then flow back from the conduit to the inside of the collection box 12 to complete the circulation of the hot air. During the circulation process of the hot air, the hot air will heat the rotating rod 5, the stirring tube 11 and the heating ring 10 respectively. The heated rotating rod 5, the stirring tube 11 and the heating ring 10 will then heat the reactants inside the cylinder 3, and the reactants in the The moisture will evaporate when heated, thereby achieving the effect of drying the reactants. During the drying process, the user turns on the motor 6 to drive the rotating rod 5 to rotate. After the rotating rod 5 rotates, it will drive the stirring tube 11 to rotate. The stirring tube 11 will stir the reactants, thereby improving the uniformity of drying the reactants. The rotating rod 5 can also break up the agglomerated reactants, further improving the drying efficiency of the reactants. After the reactants are dried, the user turns on the electric push rod 802 to drive the sealing block 803 to slide through the bottom of the discharge hole 801. At this time, the dried reactants will fall into the reactor 1 from the feed pipe 2, thereby completing the addition of the reactants. After the reactants are added, the user adds the catalyst into the reactor 1, and then allows the reactants to react with the catalyst to generate di-n-butyrate. Then the user can collect, separate and passivate the reaction products, thereby achieving the production of di-n-butyrate.

[0021] See also Figure 3 , wherein: the left side of the sealing block 803 is fixedly connected with a filter plate 16 , and the top of the filter plate 16 is in contact with the baffle 7 .

[0022] In the present invention, the filter plate 16 is set to filter the reactants when the sealing block 803 stops sealing the discharge hole 801 to release the reactants. The filter plate 16 can filter out the agglomerated reactants or impurities, effectively improving the effect of the reactants in the subsequent reaction with the catalyst and improving the practicality of the device.

[0023] See also Figure 3 and 4 , wherein: two scrapers 17 are fixedly connected to the rotating rod 5, and the bottoms of the two scrapers 17 are in contact with the baffle 7.

[0024] In the present invention, the scraper 17 can be provided to scrape off the reactants attached to the top of the baffle 7 when the rotating rod 5 rotates, thereby improving the practicality of the device.

[0025] See also Figure 4 , wherein: a guide groove 18 is provided on the scraper 17, and the guide groove 18 is V-shaped.

[0026] In the present invention, the guide groove 18 opened on the scraper 17 can collect the reactants on the top of the baffle 7 to the middle position of the scraper 17. The middle position of the scraper 17 is located at the center of the discharge hole 801, which can assist in the discharge of the reactants, increase the speed of the discharge of the reactants, and improve the practicality of the device.

[0027] See also Figure 3 and 4 , wherein: two trapezoidal blocks 19 are fixedly connected to the top of the baffle 7, two sliders 20 are fixedly connected to the outside of the baffle 7, the inner wall of the cylinder 3 is provided with two sliding grooves 21 slidably connected to the sliders 20, and the bottoms of the two sliders 20 are fixedly connected to springs 22, and the bottom ends of the two springs 22 are fixedly connected to the inner walls of the two sliding grooves 21 respectively.

[0028] In the present invention, the scraper 17 will continuously slide over the trapezoidal block 19 during the rotation. Whenever the scraper 17 slides to the inclined surface on the trapezoidal block 19, the trapezoidal block 19 will be forced to drive the baffle 7 down. After the baffle 7 drops, it will drive the slider 20 to descend along the inner wall of the slide groove 21 to compress the spring 22. After the scraper 17 slides over the trapezoidal block 19, the spring 22 will be released, and the baffle 7 will rise rapidly until it contacts the scraper 17. As the scraper 17 continues to slide over the trapezoidal block 19, the baffle 7 will reciprocate up and down. During the up and down movement, the baffle 7 will drive the reactants to roll, thereby improving the uniformity and efficiency of the drying process of the reactants, and can reduce the occurrence of reactants blocking the discharge hole 801, thereby improving the practicality of the device.

Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
