Description

Technical Field

[0001] This utility model relates to the field of epoxy resin curing agent cooling technology, and in particular to a rapid cooling device for epoxy resin curing agents. Background Technology

[0002] In the production and processing chain of epoxy resin curing agents, the curing agent will maintain a high temperature after the reaction process. If it cannot be cooled to a suitable range in time, it will not only prolong the waiting time for subsequent filling, packaging and storage, but also cause subtle changes in the internal composition of the curing agent due to prolonged high temperature, affecting the bonding performance and stability of the final product. Therefore, an efficient and stable cooling process has become a key link to ensure the production quality and efficiency of curing agents.

[0003] Traditional epoxy resin curing agent cooling devices are insufficient to meet actual production needs. Most devices have a simple stirring structure design, relying solely on simple stirring blades for mixing, which cannot achieve uniform mixing. This leads to localized temperature differences in the curing agent within the tank, with high temperatures in the center and low temperatures at the edges. The cooling uniformity is poor, and curing agent residues tend to adhere near the tank wall, further affecting the cooling effect. Traditional devices often rely on a single cooling pipe for water cooling, which has a limited contact area with the mixing tank, resulting in low heat transfer efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a rapid cooling device for epoxy resin curing agents, which can achieve uniform and rapid cooling of the curing agent while ensuring product cleanliness.

[0005] To achieve the above objectives, a rapid cooling device for epoxy resin curing agent is provided, comprising a base plate, a cooling mechanism, and a stirring mechanism. The stirring mechanism includes a stirring tank disposed above the base plate, a rotating shaft rotatably disposed in the middle of the stirring tank, a stirring blade disposed in the middle of the rotating shaft, and stirring frames fixedly disposed at both ends of the rotating shaft. The cooling mechanism includes a cooling pipe fixedly disposed on the outer surface of the stirring tank, and a plurality of heat dissipation fins fixedly disposed in the gap between the cooling pipe and the stirring tank.

[0007] According to the epoxy resin curing agent rapid cooling device, a second support is fixedly installed on the upper surface of the first support, and an exhaust fan is fixedly installed on the upper surface of the second support.

[0009] According to the epoxy resin curing agent rapid cooling device, the upper surface of the dust cover is provided with a feed pipe, the lower surface of the mixing tank is provided with a connecting pipe, and the surface of the connecting pipe is provided with a valve.

[0010] According to the epoxy resin curing agent rapid cooling device, an input pipe is fixedly provided at the upper end of the cooling pipe, and an output pipe is fixedly provided at the lower end of the cooling pipe.

[0011] According to the epoxy resin curing agent rapid cooling device, the stirring frame is rotatably connected to the inner wall of the stirring tank.

[0013] This utility model has the following beneficial effects: 1.

Detailed Implementation

[0017] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0018] Reference Figure 1-3 This utility model provides a rapid cooling device for epoxy resin curing agent, which includes a base plate 1, a cooling mechanism 4, and a stirring mechanism 5. The stirring mechanism 5 includes a stirring tank 10 disposed above the base plate 1. A rotating shaft 15 is rotatably disposed in the middle of the stirring tank 10. A stirring blade 14 is disposed in the middle of the rotating shaft 15. Stirring frames 11 are fixedly disposed at both ends of the rotating shaft 15. The cooling mechanism 4 includes a cooling pipe 19 fixedly disposed on the outer surface of the stirring tank 10. A plurality of heat dissipation fins 20 are fixedly disposed in the gap between the cooling pipe 19 and the stirring tank 10.

[0019] A first support 9 is fixedly mounted on the upper surface of the mixing tank 10. A motor 8 is fixedly mounted in the middle of the upper surface of the first support 9. The output end of the motor 8 rotates through the first support 9 and is fixedly connected to the rotating shaft 15. A second support 6 is fixedly mounted on the upper surface of the first support 9. A fan 7 is fixedly mounted on the upper surface of the second support 6.

[0020] The motor 8 drives the rotating shaft 15 to rotate, which in turn drives the stirring frame 11 and the stirring blade 14 to rotate synchronously, so that the curing agent flows fully in the mixing tank 10 and avoids local overheating.

[0021] Cooling pipes 19 are spirally wound around the outer surface of the mixing tank 10. Cold water continuously flows in from the upper inlet pipe 16, absorbs heat, and is directly discharged from the lower outlet pipe 21. Heat dissipation fins 20 increase the heat dissipation area of ​​the outer wall of the mixing tank 10, quickly dissipating the heat transferred from the curing agent inside the tank to the tank wall. Combined with the cold water from the cooling pipes 19, this forms a double cooling effect on the tank wall.

[0022] The exhaust fan 7 draws the hot air generated by the curing agent in the mixing tank 10 out from inside the dust cover 18 and directly to the outside, avoiding the accumulation of hot air in the tank and the resulting decrease in cooling efficiency.

[0023] A dust cover 18 is fixedly installed on the lower surface of the first support 9, and the dust cover 18 is adapted to the upper surface of the mixing tank 10. A feed pipe 17 is provided through the upper surface of the dust cover 18, and a connecting pipe 12 is provided through the lower surface of the mixing tank 10. A valve 13 is provided on the surface of the connecting pipe 12. The epoxy resin curing agent to be cooled is injected into the mixing tank 10 through the feed pipe 17, and the dust cover 18 prevents dust contamination.

[0024] An input pipe 16 is fixedly installed at the upper end of the cooling pipe 19, and an output pipe 21 is fixedly installed at the lower end of the cooling pipe 19. The stirring frame 11 is rotatably connected to the inner wall of the stirring tank 10.

[0025] Four support legs 3 are fixedly installed on the upper surface of the base plate 1. The mixing tank 10 is fixedly installed on the upper surface of the four support legs 3. The support legs 3 are vertically fixed to the upper surface of the base plate 1, and the upper end is fixedly connected to the lower surface of the mixing tank 10. The function is to raise the mixing tank 10 and reserve operating space for the connecting pipe 12 and valve 13 below. Four positioning holes 2 are opened on the upper surface of the base plate 1. The positioning holes 2 are used for the fixed installation of the device on the ground or production line to prevent displacement during operation.

[0026] Working principle: Fix the device to the designated position on the production line through the positioning hole 2 of the base plate 1, close the valve 13 of the connecting pipe 12, connect the input pipe 16 of the cooling pipe 19 to the external cold water supply system, connect the output pipe 21 to the wastewater recovery pipe, and start the exhaust fan 7 to create a slight negative pressure inside the dust cover 18.

[0027] The epoxy resin curing agent to be cooled is injected into the mixing tank 10 through the feed pipe 17. The motor 8 is started, and the output end of the motor 8 drives the rotating shaft 15 to rotate, which in turn drives the stirring blade 14 to rotate synchronously with the stirring frame 11, so that the curing agent is evenly dispersed.

[0028] External cold water enters the spiral cooling pipe 19 through the inlet pipe 16. During the flow process, it absorbs the heat from the outer wall of the mixing tank 10. The heated wastewater is discharged from the outlet pipe 21. At the same time, the heat dissipation fins 20 quickly conduct the heat of the mixing tank 10 to the air, forming a dual heat dissipation of water cooling and air cooling with the cooling pipe 19. The hot air generated by the curing agent during the mixing process is drawn out from the inside of the dust cover 18 and discharged to the outside under the negative pressure of the exhaust fan 7, avoiding the accumulation of hot air.

[0029] After the curing agent temperature drops to the target value, turn off the motor 8, the cold water supply system and the exhaust fan 7, and slowly open the valve 13. The cooled curing agent is discharged to the subsequent process equipment through the connecting pipe 12.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
