Description

Technical Field

[0001] The utility model relates to the technical field of cooling devices, in particular to a rapid cooling device for epoxy resin curing agent processing. Background Technique

[0002] Epoxy resin curing agent is a substance that reacts chemically with epoxy resin to form a network three-dimensional polymer, enclosing the composite material aggregate in the network, promoting the curing reaction, and making the linear resin into a tough solid-shaped additive. Epoxy floors are mostly used for underground garage floors, which are cheap and practical. Epoxy curing agents can be divided into alkaline epoxy curing agents and acidic epoxy curing agents according to their chemical structures, and can be divided into addition-type epoxy curing agents and catalytic-type epoxy curing agents according to their curing mechanisms. When producing epoxy curing agents, heat is released and the temperature is relatively high, which affects the quality of the products. Therefore, it is of great significance to cool epoxy curing agents in a timely, efficient and rapid manner.

[0003] At present, the rapid cooling devices for epoxy resin curing agent processing generally adopt methods such as air cooling, water cooling or natural cooling. However, the overall process of this method is relatively slow, and when water cooling is used for cooling, the contact area with the curing agent is small, and the problem of ineffective cooling occurs. For a large amount of epoxy resin curing agent piled up at the bottom, the cooling efficiency is low. Therefore, we have proposed a rapid cooling device for epoxy resin curing agent processing. Content of the Utility Model

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0005] A rapid cooling device for epoxy resin curing agent processing of the utility model includes a cooling tank. A stirring barrel is fixedly welded inside the cooling tank.

[0023] The following is a description of the preferred embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present utility model, and are not intended to limit the present utility model.

[0024] Embodiment: As Figures 1-5 shown, a rapid cooling device for processing an epoxy resin curing agent of the present utility model includes a cooling tank 1. A stirring barrel 101 is fixedly welded inside the cooling tank 1. A connecting pipe 2 is fixedly welded to the upper end of the stirring barrel 101. A screw feeder 3 is fixedly installed on one side of the connecting pipe 2. A driving motor 4 is bolted to the lower end of the screw feeder 3. The output end of the driving motor 4 is drivingly connected to a screw feeding shaft 5. Screw feeding blades 6 are fixedly welded to the outer periphery of the screw feeding shaft 5. A material receiving pipe 7 is fixedly welded to the lower end of the screw feeder 3, and the material receiving pipe 7 is fixedly connected to the stirring barrel 101.

[0025] Among them, a power motor 8 is bolted to the top of the cooling tank 1 through a connecting plate. The output end of the power motor 8 is drivingly connected to a rotating shaft 9. Stirring blades 10 are fixedly welded to the outer periphery of the rotating shaft 9. A stirring rod 11 is fixedly welded to the lower end of the rotating shaft 9. By providing the stirring rod 11, the contact area between the curing agent and the inner wall of the stirring barrel 101 can be increased, so that the curing agent is cooled evenly.

[0026] Among them, a cooling water pipe 12 is fixedly installed inside the cooling tank 1. The cooling water pipe 12 is fixedly connected to the mixing barrel 101. A water tank 13 is fixedly installed at the lower end of the outer side of the cooling tank 1. By setting the cooling water pipe 12, the water is circulated in the snake-shaped cooling water pipe 12 by using the water tank 13 and the refrigerator, reducing the temperature of the mixing barrel 101, and the cooling effect can be improved.

[0027] Among them, a return pipe 14 is fixedly connected to the upper end of the water tank 13. The return pipe 14 is communicated with the cooling water pipe 12, and the cooling water pipe 12 is communicated with the water tank 13. By setting the return pipe 14, the function of cold water circulation is realized, accelerating the cooling speed and not needing to change water continuously.

[0028] Among them, a heat dissipation fan 15 is fixedly installed at the top of the mixing barrel 101, and a heat dissipation port 16 is opened on one side close to the heat dissipation fan 15. By setting the heat dissipation fan 15, the heat dissipation fan 15 can dissipate the air in the mixing barrel 101 through the heat dissipation port 16, accelerating the cooling speed of the curing agent.

[0029] Among them, a feed inlet 17 is fixedly connected to the upper part of the mixing barrel 101, a discharge outlet 18 is fixedly connected to the lower part of the mixing barrel 101, and a discharge valve 19 is fixedly installed on one side of the discharge outlet 18. By setting the discharge valve 19, the discharge speed can be controlled, enabling the cooled curing agent to be discharged quickly.

[0030] Among them, the bottom of the mixing barrel 101 is funnel-shaped, a bracket 20 is fixedly welded to the outer side of the cooling tank 1, and a refrigerator is arranged inside the water tank 13. By setting the bracket 20, the stability of the cooling device is increased, enabling the cooling tank 1 to be used stably.

[0031] Working principle: When in use, pour the epoxy curing agent into the stirring barrel 101 from the feeding port 17, start the refrigerator, and use the water tank 13 and the refrigerator to circulate water in the serpentine cooling water pipe 12 to reduce the temperature of the inner wall of the stirring barrel 101. Since the serpentine cooling area is relatively large, it can improve the cooling effect and is conducive to accelerating the cooling speed. Through the return pipe 14, the water in the cooling water pipe 12 returns to the water tank 13, realizing the function of cold water circulation, accelerating the cooling speed and not needing to change water continuously, which can effectively improve the internal cooling effect of the stirring barrel 101. Start the power motor 8 to drive the rotating shaft 9 and the stirring blades 10 to rotate, stirring the curing agent inside the stirring barrel 101, so that the temperature of the curing agent in the cooling tank 1 drops, which can increase the contact area with the inner wall of the cooling tank 1, making the cooling uniform and the temperature drop rapidly. The heat dissipation fan 15 dissipates the air in the cooling tank 1 through the heat dissipation port 16 to accelerate the cooling speed. Start the driving motor 4 to rotate the spiral feeding shaft 5 and drive the spiral feeding blades 6 to rotate, so that the curing agent that has not been evenly cooled and precipitated at the bottom of the stirring barrel 101 is discharged into the top of the inside of the stirring barrel 101 through the spiral feeder 3, cooperating with the stirring rod to accelerate stirring, making the curing agent evenly cooled and preventing uneven cooling.
