[0024] The present invention will be further described below in conjunction with the embodiments.

[0025] See also Figure 1-4 The utility model provides a methyltetrahydrophthalic anhydride reaction device, including a reactor body 1, the reactor body 1 also includes a mounting ring 2, the mounting ring 2 is tightly sleeved on the reactor body 1, a discharge pipe 3 connected to the inside is fixed to a side wall of one side of the reactor body 1, two symmetrically distributed feed pipes 4 are fixed to the top side wall of the reactor body 1, the feed pipes 4 are connected to the inside of the reactor body 1, and a stirring component 5 is arranged inside the reactor body 1.

[0026] Further Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it is worth specifically explaining that the stirring assembly 5 includes a driving shaft 51, which is rotatably connected to the inner side wall of the reactor body 1, and a servo motor 52 is fixed to the top side wall of the reactor body 1, and one end of the output shaft of the servo motor 52 is coaxially fixed to the driving shaft 51. Two symmetrically distributed scraper plates 53 are tightly sleeved on the outer surface of the driving shaft 51, and one side of the scraper plate 53 is in contact with the inner side of the reactor body 1; multiple stirring rods 54, multiple stirring rods 54 are symmetrically distributed and fixed to the outer surface of the driving shaft 51, and one end of the stirring rod 54 away from the driving shaft 51 is fixed to the side wall of one side of the scraper plate 53, and multiple stirring rods 54 are fixed to the outer surface of the driving shaft 51. Connecting rods a55 are distributed in a circle, and a stirring impeller a56 is fixed at one end of the connecting rod a55 away from the driving shaft 51. A plurality of connecting rods b57 distributed in a circle are fixed on the outer surface of the driving shaft 51, and a stirring impeller b58 is fixed at one end of the connecting rod b57 away from the driving shaft 51. Through the arrangement of the stirring assembly 5, the material inside the reactor body 1 can be stirred more thoroughly and evenly, which has a better guarantee for the reaction processing effect of methyltetrahydrophthalic anhydride, avoids the situation where the material adheres to the inner wall of the reactor body 1 and causes waste, greatly improves the mixing and stirring effect of methyltetrahydrophthalic anhydride, and has a compact structure and is easy to operate.

[0027] Further Figure 2 As shown, it is worth explaining in detail that a plurality of connecting rods a55 are commonly fixed with a reinforcing ring a6 on their outer surfaces, and a plurality of connecting rods b57 are commonly fixed with a reinforcing ring b7 on their outer surfaces, and the reinforcing ring b7 is located between two reinforcing rings a6. By arranging the reinforcing ring a6 and the reinforcing ring b7, the connection reliability between the connecting rods a55 and b57 and the driving shaft 51 is greatly improved, thereby improving the stability of the connecting rods a55 and b57.

[0028] The present solution has the following working process: when methyltetrahydrophthalic anhydride needs to be processed by reaction, the feed pipe 4 is used to feed the material into the reactor body 1 to ensure that the reactor body 1 has a sufficient amount of methyltetrahydrophthalic anhydride. The driving shaft 51 is driven by the servo motor 52 to rotate synchronously, driving the scraper plate 53 to operate synchronously and the stirring rod 54 to rotate synchronously. The scraper plate 53 scrapes off the material adhered to the inner wall of the reactor body 1. With the setting of the stirring rod 54, the material inside the reactor body 1 can be stirred. The rotation of the driving shaft 51 makes the connection Rod a55 and connecting rod b57 rotate synchronously, thereby driving stirring impeller a56 and stirring impeller b58 to operate synchronously, and fully stirring the materials inside the reactor body 1. When the shock absorbing strength of the reactor body 1 needs to be adjusted, the screw 10 is synchronously operated by rotating the knob 15. The threaded transmission effect between the screw 10 and the screw hole is utilized to make the screw 10 move downward in a spiral after being stressed, so that the connecting ring 13 moves downward after being stressed. At this time, the damper 12 and the spring 14 are in a compressed state, thereby increasing the support hardness of the reactor body 1.

[0029] According to the above working process, it can be known that through the setting of the stirring component 5, the materials inside the reactor body 1 can be stirred more thoroughly and evenly, which has a good guarantee for the reaction processing effect of methyltetrahydrophthalic anhydride, avoids the situation where the materials adhere to the inner wall of the reactor body 1 and cause waste, greatly improves the mixing and stirring effect of methyltetrahydrophthalic anhydride, has a compact structure and is easy to operate, and through the setting of the spring 14, the damper 12 and the screw 10, the hardness of the support for the reactor body 1 can be adjusted, thereby reducing the degree of shaking of the reactor body 1 during operation, which has a good guarantee for the reactor body 1 and ensures that the reactor body 1 is in a relatively stable state when stirring and mixing the materials.

By setting the reinforcement ring a6 and the reinforcement ring b7, the stability when following the driving shaft 51 can be ensured, and the shaking and instability caused by the axis deviation can be avoided.

Through the arrangement of the spring 14, the damper 12 and the screw rod 10, the hardness of the support for the reactor body 1 can be adjusted, thereby reducing the degree of shaking generated by the reactor body 1 during operation, which has better protection for the reactor body 1 and ensures that the reactor body 1 is in a relatively stable state when stirring and mixing the materials.
