Description

Technical Field

[0001] This utility model relates to the field of curing device technology, specifically a rapid curing device for hydroxyl acrylic resin. Background Technology

[0002] Hydroxyacrylate resin is a thermosetting resin produced by the polymerization reaction of acrylates, methacrylates and hydroxyl-containing monomers. It combines the weather resistance and gloss of acrylic resins with the strong reactivity of hydroxyl groups. It can be cured into films with crosslinking agents such as isocyanates and amino resins. It is widely used in the coatings industry, such as automotive paints, wood coatings, and industrial anti-corrosion paints. It can give coatings excellent chemical resistance, weather resistance and mechanical properties. At the same time, it performs well in processes such as rapid curing. It is one of the key materials for achieving high-performance coatings in the modern coatings industry.

[0003] In the existing technology, the steam treatment method during the curing process of hydroxyl acrylic resin is usually to set up a simple exhaust pipe next to the curing device, with one end of the pipe connected to the curing chamber and the other end directly connected to the outdoor area or an exhaust port equipped with a simple filter screen. The steam is directly discharged by natural or small fan negative pressure, and large particulate impurities are only initially intercepted by the filter screen.

[0004] In this steam treatment method, the steam that has not undergone deep purification may contain irritating or toxic components generated during the resin curing process. Direct emission will lead to a decline in air quality in the operating workshop, and long-term exposure will damage the respiratory tract and skin of operators, posing health risks. If some of the steam is flammable gas, direct emission may also increase the safety hazards of fire and explosion. It is impossible to efficiently treat the steam generated during the curing process. To address the above problems, a rapid curing device for hydroxyl acrylic resin is proposed. Utility Model Content

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model provides a rapid curing device for hydroxyl acrylic resin. First, a negative pressure fan actively guides the flow of waste gas to form a directional airflow, ensuring that the steam generated in the curing chamber enters the treatment system quickly and completely, avoiding waste gas stagnation or leakage in the chamber, thus improving overall treatment efficiency. The filter screen intercepts large particulate impurities to prevent blockage of subsequent components. The first circulation pipe condenses the waste gas, liquefying the steam and returning it to the water tank through the second pipe, achieving resource recovery and reducing waste liquid discharge. The filter plate performs secondary interception, and the activated carbon in the frame adsorbs the fine impurities and odors, ensuring that the emitted gas meets environmental protection standards. The multi-stage synergistic treatment effectively avoids the direct emission of volatile organic compounds or harmful vapors generated during the curing process, reducing the impact on the health of operators and the environment.

[0023] 2. This utility model provides a rapid curing device for hydroxyl acrylic resin. A heating filament directly heats the heat transfer oil in the oil tank. The heat transfer oil exchanges heat with the curing chamber through a second circulation pipe, resulting in high heat transfer efficiency and rapid temperature increase within the curing chamber. This shortens the preheating time for resin curing. A first motor drives a gear set to stir the heat transfer oil with a stirring rod, ensuring uniform oil temperature distribution and preventing localized overheating or uneven temperature distribution. This ensures consistent heating of the resin in all areas of the curing chamber, improving the stability of the curing quality. The coordinated heating and cooling allows for dynamic temperature adjustment during the curing process according to actual needs. It can rapidly raise the temperature to initiate the curing reaction and promptly lower the temperature when it is too high, preventing performance defects in the resin due to abnormal temperature.

[0030] Reference Figure 2 and Figure 4 The temperature control component includes an oil tank 15, which is fixedly connected to the front end of the top side of the base plate 1. A first motor 16 is fixedly connected to the top of the oil tank 15, and a gear set 17 is fixedly connected to the output end of the first motor 16. The first motor 16 drives the gear in the middle of the gear set 17 to rotate, causing the gears on both sides to rotate synchronously. A stirring rod 18 is fixedly connected to the bottom of each gear set 17, with the middle stirring rod 18 rotating in the opposite direction to the stirring rods on both sides. An oil pump 19 is fixedly connected to the middle of the bottom of the inner wall of the oil tank 15, and the rear end of the bottom of the inner wall of the oil tank 15 is fixedly connected to... A heating filament 21 is connected to heat the heat transfer oil in the oil tank 15. The output end of the oil pump 19 is fixedly connected to a second circulation pipe 20, which transfers the heat transfer oil in the oil tank 15. The outer ring of the second circulation pipe 20 passes through and is fixedly connected to the curing box 24. The second circulation pipe 20 heats or cools the curing box 24.

The output end of the second water pump 22 is fixedly connected to a third circulation pipe 23, which cools the heat transfer oil in the oil tank 15.

[0031] Working principle: First, the material is placed in the curing chamber 24. The curing device is controlled by an external controller. The heat transfer oil in the oil tank 15 is heated by the heating filament 21. At the same time, the first motor 16 drives the gear set 17 to rotate, which drives the stirring rod 18 at the bottom to stir the heat transfer oil, making the oil temperature uniform. The oil pump 19 delivers the heated heat transfer oil to the curing chamber 24 through the second circulation pipe 20. The heat of the heat transfer oil is used to heat and cure the hydroxyl acrylic resin in the chamber. The temperature sensor 29 monitors the temperature in the curing chamber 24 in real time. When the temperature is too high or cooling is required, the heating filament 21 turns off the heating of the heat transfer oil. The coolant in the water tank 2 is delivered by the second water pump 22 to the third circulation pipe 23, which is connected to the oil tank 15. Through heat exchange and stirring by the stirring rod 18, the heat transfer oil in the oil tank 15 is cooled down, thereby... The temperature inside the curing chamber 24 is lowered, achieving dynamic temperature control. The steam generated during the curing process is guided by the negative pressure fan 7, causing the exhaust gas to be discharged through the first pipe 11. The filter screen 14 at the top of the pipe first intercepts large particulate impurities in the exhaust gas. After the exhaust gas enters the condensation chamber 3, the negative pressure fan 7 guides the flow of the exhaust gas. At the same time, the first circulation pipe 6 in the condensation chamber 3 condenses the exhaust gas into liquid, which flows back to the water tank 2 through the second pipe 31. The uncondensed gas is then filtered by the filter plate 9 and then passes through the activated carbon and other purification substances in the frame 8, achieving the purification treatment of the exhaust gas. When it is necessary to disassemble the frame 8 or the filter screen 14, the frame 8 or the sealing end cover 12 can be released by rotating the first bolt 10 or the second bolt 13, thereby enabling the disassembly of the frame 8 and the filter screen 14.
