Description

Technical Field

[0001] This utility model relates to the field of separation and purification equipment technology, and more specifically, it relates to a separation and purification equipment for epoxy resin curing agents. Background Technology

[0002] Epoxy resin is a high molecular weight polymer containing two or more epoxy groups in its molecule. It is a thermosetting material that forms a three-dimensional network structure through reaction with a curing agent. Epoxy resin curing agents are additives that chemically react with epoxy resin to form this network of three-dimensional polymers. They transform linear resins into tough, three-dimensional solids and are widely used in adhesives, coatings, and composite materials. During the production of epoxy resin curing agents, separation and purification equipment is required to improve the purity of the curing agent. In related technologies, a separation and purification device for epoxy resin curing agent can accelerate the dissolution of solid materials through a heater, so that the stirring chamber is heated evenly, improving the purification efficiency. At the same time, it can also avoid the blockage of the solenoid valve due to uneven dissolution of materials. The speed regulator controls the speed of the motor, which improves the reaction rate. The existing technical solutions mentioned above have the following drawbacks: when heating the heater, the liquid inside is heated from the outside to the inside, which results in uneven heating and low heating efficiency of the liquid inside while the liquid outside is heated. Furthermore, the gas evaporated during heating cannot be directly processed, which is time-consuming and labor-intensive. Utility Model Content

Obviously, the specific embodiments described are only a part of the embodiments of this utility model, and not all of them.

[0016] Example: This utility model provides a technical solution: a separation and purification device for epoxy resin curing agents, such as... Figure 1 and Figure 2 It includes a tank body 1, a heating cylinder 2 connected inside the tank body 1, and an annular cooling box 18 connected to the tank body 1, such as... Figure 3A cooling box 18 is fitted onto a tank 1; a thermoelectric cooling plate 3 is connected to the tank 1, with the hot end of the thermoelectric cooling plate 3 located between the inner wall of the tank 1 and the heating cylinder 2, and the cold end of the thermoelectric cooling plate 3 located between the surface of the tank 1 and the cooling box 18; a sealing cover 4 is connected to the top of the tank 1, and a rotating shaft 5 is rotatably connected to the sealing cover 4; an air outlet 10 is opened on the sealing cover 4, and multiple drive blades 20 are arranged inside the air outlet 10.

[0017] Specifically, such as Figure 4 and Figure 5 The bottom end of the rotating shaft 5 is connected to a fixed base 6. Multiple connecting rods 7 are connected to the bottom of the fixed base 6, and each connecting rod 7 has a stirring tube 8 connected to its bottom end. All stirring tubes 8 are located inside the heating cylinder 2. A motor 9 is connected to the top of the sealing cover 4. The top of the rotating shaft 5 is connected to the output shaft of the motor 9. A ventilation cylinder 11 is connected to the top of the air outlet 10. A bearing seat 12 is connected inside the air outlet 10, located at the center of the air outlet 10. A movable shaft 13 is rotatably connected inside the bearing seat 12. Both the movable shaft 13 and the rotating shaft 5 are connected to drive wheels 14. Both drive wheels 14 are located inside the tank body 1, and the same belt 15 is fitted onto both drive wheels 14. An air outlet pipe 16 is provided at the top of the ventilation cylinder 11. Multiple drive blades 20 are connected to the surface of the movable shaft 13, and the multiple drive blades 20 are evenly distributed on the movable shaft 13. Figure 6 The top of the cooling box 18 is connected to a ventilation pipe 17, and the other end of the ventilation pipe 17 is connected to the output end of the air outlet pipe 16. The bottom of the cooling box 18 is connected to a water outlet 19. The bottom of the tank body 1 is provided with a discharge port 21. The bottom of the heating cylinder 2 is provided with a discharge port 22. An electric push rod 23 is connected to one side of the inner wall of the tank body 1. The output end of the electric push rod 23 is connected to a baffle 24, which cooperates with the discharge port 22. By adopting the above technical solution, the curing agent placed in the heating cylinder 2 is stirred during heating through the stirring tube 8. During stirring, due to the influence of gravity, the curing agent at the bottom of the heating cylinder 2 is drawn out through the stirring tube 8 and discharged at the top of the stirring tube 8. During stirring, the steam generated by the internal heating is driven to be discharged through the movable shaft 13, transmission wheel 14, belt 15 and ventilation tube 11. The liquid generated by the cooling of the steam is discharged through the water outlet 19. The purified curing agent in the heating cylinder 2 is discharged through the electric push rod 23 and baffle 24.

[0018] The working principle of this utility model is as follows: During use, the operator pulls the sealing cap 4 off the tank body 1. After the sealing cap 4 detaches from the tank body 1, the heating cylinder 2 is exposed, allowing the operator to easily add the curing agent to be purified into the heating cylinder 2. After adding the appropriate dosage, the operator operates the sealing cap 4 to cover the tank body 1, sealing it with the tank body 1. The sealing cap 4 then drives the stirring tube 8 into the heating cylinder 2. After the sealing cap 4 is sealed with the tank body 1, power is supplied to the thermoelectric cooling element 3, causing it to start working. The hot end of the thermoelectric cooling element 3 located on the inner wall of the tank body 1 begins to generate heat, heating the heating cylinder 2 inside the tank body 1. Heating cylinder 2 heats up, transferring heat to the curing agent placed inside, thus heating the curing agent. Motor 9 operates, driving shaft 5 to rotate, which in turn drives connecting rod 7 to rotate, causing stirring tube 8 to rotate inside heating cylinder 2. This stirs the curing agent inside heating cylinder 2. During stirring, the inclined stirring tube 8 causes gas inside it to be ejected, drawing the curing agent from the bottom of heating cylinder 2 through the bottom of the stirring tube 8. Due to gravity, the curing agent is ejected from the top of the stirring tube 8, allowing the curing agent at the bottom of heating cylinder 2 to move to the top, thus... The heating process results in more uniform temperature distribution and better heating effect. During heating, the curing agent begins to evaporate, thus purifying it. The gas generated during evaporation is located at the top of the heating cylinder 2. When the motor 9 drives the rotating shaft 5, the shaft 5 drives the transmission wheel 14 on it to rotate. This, in turn, drives the transmission wheel 14 on the movable shaft 13 via the belt 15, causing the movable shaft 13 to rotate on the bearing seat 12. This, in turn, causes the drive blades 20 on the movable shaft 13 to rotate within the air outlet 10, thereby discharging the steam from the tank 1 into the air outlet 16. The steam then enters the ventilation duct 17 and finally enters the cold air supply system. Inside the cooling box 18, after steam enters the cooling box 18, the cold end of the thermoelectric cooling plate 3 located on the surface of the tank 1 and the cooling box 18 cools the cooling box 18, thereby cooling the steam discharged into the cooling box 18 into liquid, which is then discharged at the outlet 19, facilitating direct steam processing, making operation convenient and more portable. After purification, by supplying power to the electric push rod 23, the electric push rod 23 shortens, driving the baffle 24 to move away from the discharge port 22, thereby opening the discharge port 22 and discharging the purified curing agent in the heating cylinder 2 through the discharge port 21, facilitating subsequent collection and processing operations by the staff.

[0019] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
