Description

Technical Field

[0001] The utility model relates to the technical field of curing agent processing, in particular to a resin curing agent reaction kettle with a defoaming function. Background Art

[0002] During the processing of resin curing agents, the formation of bubbles is a common problem. The presence of bubbles not only affects the uniformity of the mixture, but may also cause defects in the final product, such as holes and cracks, thereby affecting the mechanical properties and service life of the product.

[0003] The viscosity of the resin and curing agent may change significantly during the mixing process. Especially after the curing agent is added, the viscosity of the system increases rapidly due to the initiation of the chemical reaction. This change in viscosity reduces the fluidity of the mixture, making it difficult for bubbles to rise and escape naturally. Furthermore, the viscosity of the stirred mixture increases further during cooling, trapping bubbles in the resin and making them difficult to remove by conventional methods.

[0004] Traditional stirring equipment often cannot effectively solve the bubble problem because they fail to fully consider the impact of changes in the mixture's viscosity on bubble escape. Air will be introduced during the stirring process, and when the stirred mixture cools, the bubbles are more likely to be locked in the resin. Therefore, a resin curing agent reactor with a defoaming function is needed to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a resin curing agent reaction kettle with a defoaming function, so as to solve the problem in the background art that the resin curing agent is prone to generate bubbles during the processing.

The feed hopper is located at the top of the reactor body, and a valve is installed inside the feed hopper. The movable shaft is movably connected to the middle end of the reactor body. The first scraper and the second scraper are in contact with the inner wall of the reactor body, and the first scraper and the second scraper are connected to the movable shaft through the stirring rod. A suspension mechanism is installed between the first scraper and the movable shaft. The suspension mechanism includes a movable seat, a high-temperature resistant float, a guide plate and a scraper. A slide groove is provided inside the first scraper, and guide rails are symmetrically distributed on the outer surface of the movable shaft. The guide rails and the slide groove are slidably connected to the movable seat. The high-temperature resistant floats are evenly spaced on the bottom surface of the movable seat, and the bottom of the scraper has a serrated structure.

[0007] As a preferred technical solution of the present invention, the movable shaft and the stirring rod are hollow structures.

[0008] As the preferred technical solution of the present invention, a heating power supply is installed at the bottom of the kettle body, and a heating coil is connected to the output end of the heating power supply.

[0009] As a preferred technical solution of the present invention, the heating ring is distributed inside the stirring rod, and a heat conducting sheet is distributed in an annular manner on the outer surface of the stirring rod.

[0019] See also Figure 1-4The utility model provides a technical solution: a resin curing agent reactor with a defoaming function, comprising a reactor body 1, a feed hopper 2, a movable shaft 6, a stirring rod 10, a first scraper 11 and a second scraper 12. The feed hopper 2 is located at the top of the reactor body 1, and a valve 3 is installed inside the feed hopper 2. The movable shaft 6 is movably connected to the middle end of the reactor body 1, and the first scraper 11 and the second scraper 12 are in contact with the inner wall of the reactor body 1, and the first scraper 11 and the second scraper 12 are connected to the movable shaft 6 through the stirring rod 10. A suspension mechanism is installed between the first scraper 11 and the movable shaft 6, and the suspension mechanism includes a movable seat 13, a high-temperature resistant float 14, a guide plate 16 and a scraper 17. A slide groove 18 is opened inside the first scraper 11, and guide rails 21 are symmetrically distributed on the outer surface of the movable shaft 6. The guide rails 21 and the slide groove 18 are slidably connected to the movable seat 13. The high-temperature resistant floats 14 are evenly spaced on the bottom surface of the movable seat 13, and the bottom of the scraper 17 has a serrated structure.

[0020] The interior of the movable shaft 6 and the stirring rod 10 is a hollow structure. The internal space of the movable shaft 6 and the stirring rod 10 can provide a line installation path for the heating ring 20, and can also fix the position of the heating ring 20 to ensure normal heat conduction inside the stirring kettle.

[0021] A heating power supply 15 is installed at the bottom of the kettle body 1, and a heating coil 20 is connected to the output end of the heating power supply 15. The heating coil 20 is started by the heating power supply 15 to heat the inside of the stirring kettle, thereby increasing the stirring environment temperature. When the temperature of the curing agent rises, its viscosity can be reduced, and bubbles can rise to the surface and burst more easily. At the same time, the temperature increase will increase the buoyancy of the liquid properties of the curing agent, so that the buoyancy of the high-temperature resistant float 14 is stronger, and the positioning of the scraper 17 is more accurate.

[0022] The heating ring 20 is distributed inside the stirring rod 10, and the outer surface of the stirring rod 10 is annularly distributed with heat conducting plates 19. The arrangement of multiple heat conducting plates 19 outside the stirring rod 10 can increase the heat exchange area with the curing agent, improve the heat conduction effect, and make the overall internal temperature evenly heated.

[0023] A motor 7 is installed at the top of the kettle body 1, and a small gear 8 is connected to the output end of the motor 7. A large gear 9 is connected to the outer surface of the small gear 8. The large gear 9 is fixedly connected to the top of the movable shaft 6. The motor 7 can increase the rotational torque of the movable shaft 6 through the reduction mechanism of the large and small gears. On the one hand, it avoids insufficient power due to viscosity, and at the same time prevents the air from being drawn into the mixture of resin and curing agent due to excessive rotation speed to form bubbles.

[0024] The outer surface of the kettle body 1 is symmetrically distributed with insulating outer lining plates 4, and the bottom of the insulating outer lining plates 4 is connected to a base frame support 5. The insulating outer lining plates 4 can keep the interior of the kettle body 1 in a constant temperature state, which not only saves energy and reduces consumption, but also increases the stability of the overall structural support.

[0025] Working principle: First, the curing agent and additives are discharged from the feed hopper 2 into the interior of the kettle body 1. After the discharge is completed, the heating power supply 15 is started to heat the heating ring 20. The heating ring 20 cooperates with the heat conductive sheet 19 on the outer surface of the stirring rod 10 to heat the curing agent inside the kettle body 1. After the curing agent temperature rises, its viscosity can be reduced, and bubbles are more likely to rise to the surface and burst. At the same time, the temperature increase will increase the buoyancy of the curing agent liquid property, so that the buoyancy of the high-temperature resistant float 14 is stronger. The high-temperature resistant float 14 drives the movable seat 13 to move vertically up and down along the slide 18 and the guide rail 21, so that the scraper 17 reaches the surface of the curing agent liquid, and then the motor 7 is started to stir the inside of the kettle body 1. The low-speed stirring can prevent the air from being drawn into the mixture of resin and curing agent due to excessive speed, forming bubbles, and during the rotation process, the scraper 17 uses its own serrated structure to puncture the bubbles that rise to the surface of the curing agent, which can help the bubbles burst and merge into the resin. The processed curing agent is discharged from the discharge pipe at the bottom of the kettle body (1).
