Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and in particular to a phenolic resin reaction vessel. Background Technology

[0002] Phenolic resins have a wide range of applications. In the construction industry, they are used to manufacture insulation materials and adhesives, effectively providing thermal insulation and bonding to building materials. In the electrical industry, they can be used to make insulating materials and switch housings, ensuring the safe operation of electrical equipment. In aerospace, they are used to manufacture high-temperature resistant structural components that can withstand extreme environments. In daily consumer goods, they can be used to produce tableware, handles, etc., exhibiting good wear resistance and heat resistance. Furthermore, they also have important applications in coatings and grinding wheels.

[0003] The purpose of a phenolic resin reactor is to provide a suitable reaction environment for the synthesis of phenolic resins. By precisely controlling parameters such as reaction temperature, pressure, and stirring speed, phenols and aldehydes undergo a condensation reaction under specific conditions to produce phenolic resins with specific properties. Its significance lies in enabling industrial-scale production, ensuring the stability and consistency of product quality, improving production efficiency, reducing costs, and providing strong support for the widespread application of phenolic resins in multiple fields.

[0004] In existing technologies, some phenolic resin reactors are generally processed by directly adding reactants into the reactor. This makes it difficult to accurately control the amount of each reactant during feeding, resulting in an imbalance in the raw material ratio, which affects the performance and quality of the phenolic resin. Furthermore, adding a large amount of reactants at once will cause the initial concentration to be too high and the reaction rate to be too fast, making it difficult to maintain stable reaction conditions, triggering side reactions, and reducing product purity. Therefore, a phenolic resin reactor is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a phenolic resin reaction vessel, which aims to improve the problem caused by the difficulty in accurately controlling the amount of each reactant during feeding, which is due to the direct addition of reactants into the interior of the reaction vessel for processing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A phenolic resin reaction vessel includes a tank body. A feed pipe is fixedly connected to the inner wall of the tank body. A fixed outer shell is fixedly connected to the outer wall of the feed pipe. A drive motor is fixedly connected to the inner wall of the fixed outer shell. A transmission gear is fixedly connected to the drive end of the drive motor. A main gear is rotatably connected to the inner wall of the fixed outer shell. The outer wall of the main gear and the outer wall of the transmission gear are meshed with each other. Multiple connecting rods are fixedly connected to the outer surface of the feed pipe. A filter screen is detachably connected to the inner wall of the tank body. A disassembly assembly for disassembly is installed on the inner wall of the filter screen.

[0008] As a further description of the above technical solution:

[0009] The disassembly assembly includes a fixed shell, the outer wall of which is fixedly connected to the outer wall of the filter screen, the inner wall of which is detachably connected to an installation post, the inner wall of which is detachably connected to multiple locking blocks, the outer walls of which are all fixedly connected to elastic springs, and the outer wall of which is provided with multiple limiting holes.

[0010] As a further description of the above technical solution:

[0011] A sliding rod is fixedly connected to the inner wall of the mounting column, a button is slidably connected to the inner wall of the sliding rod, and a control rod is fixedly connected to the outside of the button.

[0012] As a further description of the above technical solution:

[0013] Multiple reset blocks are fixedly connected to the outer wall of the control rod, and the outer walls of the multiple reset blocks are slidably connected to the inner wall of the slide rod. The inner wall of the slide rod is provided with a sliding groove.

[0014] As a further description of the above technical solution:

[0015] A return spring is fixedly connected to the bottom of the control lever, and the other end of the return spring is fixedly connected to the inner wall of the slide rod.

[0016] As a further description of the above technical solution:

[0017] The inner wall of the connecting rod is provided with a control groove, and a sliding rod is slidably connected to the inner wall of the connecting rod;

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the drive motor starts, which drives the transmission gear to rotate. The rotation of the transmission gear drives the main gear to rotate. The rotation of the main gear causes the sliding groove on the inner wall of the main gear to drive the opening and closing plate to start rotating. The rotation of the opening and closing plate causes the sliding rod to move along the trajectory of the control groove on the inner wall of the connecting rod. This achieves the rotation and opening of the opening and closing plate to limit the amount of material fed into the feeding pipe, thereby achieving more precise feeding and making the internal reaction more accurate.

[0024] 2. In this utility model, pressing the button causes the control lever to move, which in turn causes the reset block to move inside the groove on the outer wall of the slide rod. The movement of the reset block causes it to contact the locking block. Under the contact of the reset block, the locking block is retracted into the inner wall of the fixed shell by the elastic spring. At this time, the locking block is no longer locked into the inner wall of the limiting hole on the outer wall of the mounting column, thus completing the disassembly of the filter screen. This facilitates the replacement and maintenance of the filter screen and greatly improves the efficiency of maintenance. Attached Figure Description

The bottom of the opening and closing plate 9 is slidably connected to the inner wall of the main gear 8 to ensure that the opening and closing plate 9 can rotate flexibly with the rotation of the main gear 8.

[0035] Reference Figure 1 , Figure 3 and Figure 5The disassembly assembly includes a fixed housing 12, which is used to fix components such as the mounting column 17 to ensure stable installation of the disassembly assembly. The outer wall of the fixed housing 12 is fixedly connected to the outer wall of the filter screen 19, realizing the connection between the fixed housing 12 and the filter screen 19, making the disassembly assembly and the filter screen 19 a whole. The inner wall of the fixed housing 12 is detachably connected to the mounting column 17, which is used to install components such as the clamping block 14. The detachable connection facilitates maintenance and replacement.

The detachable connection facilitates the inspection of the clamping blocks 14. The outer walls of the multiple clamping blocks 14 are all fixedly connected to elastic springs 13, which allow the clamping blocks 14 to retract when subjected to external force, facilitating disassembly.

[0036] Multiple limiting holes 27 are provided on the outer wall of the mounting column 17. The limiting holes 27 cooperate with the locking block 14, and the locking block 14 is locked into the limiting holes 27 to achieve fixation. A sliding rod 22 is fixedly connected to the inner wall of the mounting column 17. The sliding rod 22 is used to provide a sliding track for components such as the button 21 and the control rod 16.

Pressing the button 21 can drive the control rod 16 and other components to move, thereby controlling the locking block 14. The control rod 16 is fixedly connected to the outside of the button 21. Pressing the button 21 will drive the control rod 16 to move, thereby transmitting force. Multiple... The reset block 18 contacts the locking block 14 when the control lever 16 moves, pushing the locking block 14 to move. The outer walls of multiple reset blocks 18 are slidably connected to the inner wall of the slide rod 22, ensuring that the reset blocks 18 can slide along the inner wall of the slide rod 22. The inner wall of the slide rod 22 is provided with a sliding groove 20, which provides a track for the sliding of the reset blocks 18.

[0037] A stirring rod 24 is rotatably connected to the inner wall of the tank 1. When the phenolic resin inside needs to be processed, the motor at the bottom of the tank 1 drives the stirring rod 24 to stir the phenolic resin inside, making the phenolic resin more uniformly mixed. A heating tube 23 is fixedly connected to the inner wall of the tank 1. While stirring, the heating tube 23 heats the phenolic resin inside, making the phenolic resin better processed and improving the processing quality. A discharge pipe 25 is fixedly connected to the outer wall of the tank 1. The discharge pipe 25 is used to discharge the processed phenolic resin from the tank 1. A discharge pump 26 is fixedly connected to the outer wall of the discharge pipe 25. The discharge pump 26 provides power so that the phenolic resin can be smoothly discharged through the discharge pipe 25.

[0038] Working principle: When the amount of material fed per unit time needs to be limited, the drive motor 5 starts. The start of the drive motor 5 drives the transmission gear 4 to rotate, and the rotation of the transmission gear 4 drives the main gear 8 to rotate. The rotation of the main gear 8 causes the sliding groove 11 opened on the inner wall of the main gear 8 to drive the opening and closing plate 9 to start rotating. The rotation of the opening and closing plate 9 causes the sliding rod 10 to move along the trajectory of the control groove 6 opened on the inner wall of the connecting rod 7. This realizes the rotation and opening of the opening and closing plate 9 to limit the amount of material fed into the feeding pipe 2, thereby achieving more precise feeding and making the internal reaction more accurate.

[0039] When the filter screen 19 needs to be cleaned or replaced, press button 21. Pressing button 21 moves control lever 16, which in turn moves reset block 18 inside the groove 20 on the outer wall of slide rod 22. The movement of reset block 18 causes it to contact locking block 14. Locking block 14 is then retracted into the inner wall of fixed housing 12 by elastic spring 13 after being touched by reset block 18. At this time, locking block 14 is no longer locked into the inner wall of limiting hole 27 on the outer wall of mounting post 17, thus completing the disassembly of filter screen 19. This facilitates the replacement and maintenance of filter screen 19 and greatly improves the efficiency of maintenance.

[0040] When the phenolic resin inside needs to be processed, the phenolic resin is added to the inner wall of the tank 1 through the feed pipe 2. Then, the motor at the bottom of the tank 1 drives the stirring rod 24 to stir the phenolic resin inside. At the same time, the heating pipe 23 heats the phenolic resin inside, so as to make the phenolic resin better processed.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
