[0001] This utility model relates to the field of resin processing technology, and more specifically to an epoxy resin reaction vessel. Background Technology

[0002] The reactor consists of a vessel body and a stirring system. The vessel body has a cavity, into which materials are poured. The stirring system heats or cools and mixes the materials to carry out a comprehensive polymerization reaction.

[0003] Epoxy resin is a high molecular polymer, and its main raw materials are bisphenol A and epichlorohydrin. In the production process, the two raw materials are usually poured into a reactor and heated to a certain temperature before being stirred and reacted. During the reaction, catalysts or solvents need to be added to improve the reaction rate and quality of epoxy resin. However, during the catalyst addition process, the reactor needs to be opened. At this time, the reactor has a high temperature and pressure. When adding auxiliary agents, workers are easily exposed to the high-temperature airflow, which poses a safety hazard. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies and to solve the issue of the difficulty in adding auxiliary agents.

[0029] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0030] like Figure 1-5 As shown, an epoxy resin reactor includes:

[0031] Tank 1, a cover 4 is provided on the tank 1, and a liquid filling port 41 is provided on the cover 4;

[0032] Stirring unit 3 is disposed on cover 4 and includes stirring rod 32 located inside tank 1;

[0033] The liquid addition unit 2 is located at the liquid addition port 41 and includes a transmission component 22, a sleeve 21, a cover plate 25, and a solution tank 26 rotatably connected to the cover plate 25. The solution tank 26 has a second opening 261 at its eccentric position. The transmission component 22 is located on the cover plate 25 and controls the solution tank 26 to rotate on the cover plate 25.

[0034] Among them, the sleeve 21 is fitted onto the solution tank 26, and the sleeve 21 has a first opening 213 that cooperates with the second opening 261;

[0035] Pressure control element 23 is disposed on cover plate 25 and is connected to solution tank 26.

[0036] Specifically, the cover 4 is provided with a buckle 42, which connects to the tank 1 to form a sealed stirring chamber. The liquid addition unit 2 can be separated from the liquid addition port 41 to add the main raw materials for the resin reaction. The raw materials are put into the stirring chamber, and then the liquid addition unit 2 is reassembled to carry out high-temperature and high-pressure stirring reaction of the resin raw materials. When it is necessary to add materials such as catalysts, the first opening 213 and the second opening 261 are misaligned in advance. The high-pressure gas in the solution tank 26 is discharged through the pressure control component 23, and then the catalyst is added in the solution tank 26. At this time, the transmission component 22 controls the solution tank 26 to rotate in the sleeve 21, so that the first opening 213 and the second opening 261 are intermittently connected, so that the catalyst and other materials are evenly discharged into the tank 1 and fully mixed with the resin raw materials, thereby improving the reaction speed and effect of the resin raw materials. After the resin reaction is completed, the drain port 12 can be opened to discharge the reacted resin and clean the inside of the tank 1.

[0037] As a further embodiment of this utility model, a bottom cover 27 is snapped onto the cover 4. A driving wheel 221 and a driven wheel 222 mesh between the bottom cover 27 and the cover 4. The solution tank 26 is snapped onto the driven wheel 222, and the sleeve 21 is snapped onto the bottom cover 27. The driving wheel 221 cooperates with the transmission component 22. The number of teeth of the driving wheel 221 is less than the number of teeth of the driven wheel 222, thereby decelerating the movement of the solution tank 26, reducing the frequency of catalyst addition, and improving the mixing efficiency of the resin. An installation space is formed between the bottom cover 27 and the cover 4. The driving wheel 221 and the driven wheel 222 are disposed in this installation space, thereby improving the protection of the driving wheel 221 and the driven wheel 222.

[0038] As a further embodiment of this utility model, a locking block 212 is provided on the sleeve 21, which engages with the bottom cover 27. The sleeve 21 is fixed to the bottom cover 27. During the feeding process, the sleeve 21 remains in a locked state, which serves to support and guide the solution tank 26.

[0039] As a further embodiment of this utility model, the transmission component 22 includes a first motor 224, a transmission box 223, and a second helical gear 226 rotatably disposed within the transmission box 223. The output end of the first motor 224 is provided with a first helical gear 225 that meshes with the second helical gear 226. The second helical gear 226 cooperates with the drive wheel 221. The first motor 224 controls the rotation of the first helical gear 225, thereby linking the rotation of the second helical gear 226 and the drive wheel 221, thereby controlling the rotation of the solution tank 26 within the sleeve 21, so that the first opening 213 and the second opening 261 are intermittently connected, that is, the material is fed intermittently, thereby avoiding the phenomenon of excessive material being fed at once, which affects the resin mixing efficiency.

[0040] As a further embodiment of this utility model, one end of the sleeve 21 is provided with a conical sleeve 211 that abuts against the solution tank 26. A first opening 213 is provided on the conical sleeve 211. Since the position of the first opening 213 is located at the eccentric part of the sleeve 21, the shape of the conical sleeve 211 is as follows: Figure 3 and Figure 5 As shown, when adding materials such as catalysts, the conical shape can improve the discharge effect of materials in the solution tank 26. Furthermore, the liquid inlet 41 is inclined on the cover 4, so that the liquid addition unit 2 is tilted accordingly, which further improves the discharge effect of materials in the solution tank 26.

[0041] As a further embodiment of this utility model, the pressure control component 23 is provided with a pressure relief pipe 233 and a pressure gauge 234. The pressure control component 23 is provided with a knob 231, which can control the opening and closing of the pressure relief pipe 233 to discharge high-pressure and high-temperature gas flow from the side through the pressure relief pipe 233. At the same time, the pressure change in the solution tank 26 can be observed in real time through the pressure gauge 234 to reduce the risk of high-pressure burns.

[0042] As a further embodiment of this utility model, a liquid adding block 24 is provided on the cover plate 25, and a liquid adding pipe 243 is provided on the liquid adding block 24. After the high-pressure air in the solution tank 26 is discharged, the material can flow from the liquid adding block 24 into the solution tank 26 through the liquid adding pipe 243. Solution or solid particles can be added into the solution tank 26.

[0043] As a further embodiment of this utility model, a float 242 is slidably disposed inside the liquid adding block 24, and a float ball 241 is disposed on the float 242. When particles or solution are added to the solution tank 26, as the amount of added material increases, the storage space also decreases. When a certain position is reached, the float ball 241 will be pushed to slide upward along the axial direction, and the float 242 will also move upward to serve as a warning. Furthermore, when the pressure inside the solution tank 26 is high, the float ball 241 and the float 242 will also be pushed to serve as a warning, reducing the risk of burns caused by high-pressure air.

[0044] As a further embodiment of this utility model, a support sleeve 28 is provided on the cover plate 25, and a rubber ring is provided on the support sleeve 28 to abut against the solution tank 26. A support plate 29 is provided on the cover plate 25, and the support sleeve 28 is snapped onto the support plate 29. The rubber ring improves the sealing between the support sleeve 28 and the solution tank 26. When a catalyst is added to the resin, the solution tank 26 can rotate on the support sleeve 28 under the drive of the driven wheel 222.

[0045] As a further embodiment of this utility model, the cover 4 is engaged with the tank 1 to form a stirring chamber, and the stirring chamber contains a mixed raw material 11. The stirring unit 3 includes a second motor 31 mounted on the cover 4. One end of the stirring rod 32 is engaged with the output end of the second motor 31, while the other end is provided with an arc-shaped stirring part 33 for stirring the mixed raw material 11. When the mixed raw material 11 in the tank 1 is stirred (e.g. Figure 5 As shown, the mixed raw material 11 is formed into a liquid state under the action of high temperature and high pressure. At the same time, under the output of the second motor 31, the stirring rod 32 drives the mixed raw material 11 to carry out a thorough mixing reaction in a vortex. When other materials are added, the materials fall intermittently from the first opening 213, so that the materials are evenly mixed into the mixed raw material 11, further improving the mixing efficiency of the resin.

[0046] The above-described technical solution of this utility model addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The parts not covered in this application's technical solution are the same as or can be implemented using existing technologies, and will not be described in detail here.
