A valve is provided on the discharge pipe 11. A support 12 is installed around the bottom of the reaction tank 1. An electric heating layer 13 is provided on the outer wall of the reaction tank 1. An insulation layer 14 is provided on the outer wall of the electric heating layer 13. The electric heating layer 13 is divided into multiple independent heating zones. Each heating zone is connected to an external power source through an independent cable. By setting multiple heating zones on the outer wall of the reaction tank 1, the temperature of each zone can be dynamically adjusted by a controller to avoid local overheating and provide a safety protection effect.

[0025] like Figure 2 and Figure 4 As shown, a lid lifting assembly 2 is installed on the upper end of the reaction vessel 1. The lid lifting assembly 2 includes a support plate 21, which is symmetrically arranged on the outer surface of the upper end of the reaction vessel 1. Each support plate 21 has a vertical plate 22 fixedly connected to its top side. A threaded rod 23 is provided on the inner side of one vertical plate 22 via a bearing, and a guide rod 24 is fixedly connected to the inner side of the other vertical plate 22. Both the threaded rod 23 and the guide rod 24 have L-shaped connecting plates 27 fitted on their outer walls. A lid 28 is attached to the bottom of the two L-shaped connecting plates 27 via screws. An annular embedded plate 281 is provided at the bottom edge of the lid 28. An annular embedded plate 281 is provided on the bottom side of the tank cover 28 and is embedded in the annular groove at the top of the reaction vessel 1 to improve the stability of the tank cover 28. The annular embedded plate 281 is embedded in the annular groove at the top of the reaction vessel 1. A bevel gear set 25 is installed at the bottom of the threaded rod 23. The bevel gear set 25 is set in the groove at the bottom of the upright plate 22. A drive motor 26 is installed at the drive end of the bevel gear set 25. The drive motor 26 is bolted to the support plate 21. A tank cover lifting assembly 2 is installed at the upper end of the reaction vessel 1. The tank cover 28 is raised and lowered by the lifting drive, which facilitates the maintenance and cleaning of the inside of the reaction vessel 1.

[0026] like Figure 2 and Figure 3As shown, a mixing assembly 3 is rotatably installed inside the reaction vessel 1. The mixing assembly 3 includes a rotating rod 31. Angled stirring rods 32 are arranged circumferentially on the upper outer wall of the rotating rod 31, extending to the inner wall of the reaction vessel 1. Multiple sets of angled stirring rods 32 are arranged vertically. Anchor-type stirring rods 34 are arranged circumferentially on the lower outer wall of the rotating rod 31, with their outer walls contacting the bottom side of the reaction vessel 1. A stirring motor 33 is installed on the top of the rotating rod 31, and the stirring motor 33 is located on the vessel cover 2. In the middle of the 8, a feed channel 282 is provided at the through hole on one side of the tank cover 28. A valve is provided on the feed channel 282. The inner wall of the reaction tank 1, as well as the inclined stirring rod 32 and the anchor stirring rod 34, are coated with a Teflon layer. The reaction tank 1 is equipped with a combined stirring paddle, with the upper part being the inclined stirring rod 32 and the lower part being the anchor stirring rod 34, which can adapt to the mixing of materials with different viscosities and increase the stirring range. The Teflon coating on the inner wall of the reaction tank 1, as well as the inclined stirring rod 32 and the anchor stirring rod 34, reduces the adhesion of epoxy resin during the heating process and reduces waste.

[0027] This utility model provides a heating reaction device for epoxy resin synthesis. The specific working principle is as follows: The valve on the feed channel 282 is opened to inject raw materials into the reaction tank 1. The stirring motor 33 is started, driving the rotating rod 31 to rotate, which in turn causes the inclined stirring rod 32 and the anchor stirring rod 34 to rotate, mixing the raw materials. During the mixing process, multiple heating zones attached to the outer wall of the reaction tank 1 are energized. The temperature of each zone is dynamically adjusted by the controller to avoid localized overheating and to provide safety protection. After the heating reaction is completed, the discharge pipe 11 is opened... The valve discharges the epoxy resin. Because the inner wall of the reaction vessel 1 and the inclined stirring rod 32 and anchor stirring rod 34 are coated with Teflon, the adhesion of epoxy resin during heating is reduced, thereby reducing waste. When maintaining or cleaning the inside of the reaction vessel 1, the drive motor 26 can be started to drive the bevel gear set 25 to rotate, which in turn causes the threaded rod 23 to rotate, causing the L-shaped connecting plate 27 to move on the threaded rod 23 and the guide rod 24, thereby causing the tank cover 28 to move away from the reaction vessel 1 until the inclined stirring rod 32 and anchor stirring rod 34 are removed from the reaction vessel 1.

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