Description

Technical Field

[0001] This utility model relates to the field of paint film baking technology, specifically to an electromagnetic wire paint film baking device. Background Technology

[0002] Electromagnetic wire, also known as winding wire, is a type of conductive metal wire with a special insulation layer, specifically used in the manufacture of coils or windings in electrical products. Its core function is based on Faraday's law of electromagnetic induction, generating a magnetic field through current or inducing current by cutting magnetic lines of force, thus achieving the efficient conversion between electrical and magnetic energy. Electromagnetic wire consists of a conductor and an insulation layer, and is manufactured through precision annealing and coating processes.

[0003] Authorization announcement number CN222220190U discloses an electromagnetic wire coating baking machine, including a baking oven. The top of the baking oven has an air inlet and an air outlet. An acetic acid storage tank is fixedly connected to the outside of the baking oven. An absorption component is installed on the acetic acid storage tank and the baking oven. This invention uses a negative pressure fan to draw gas from inside the baking oven and introduces it into an acetic acid solution through a conduit, allowing the acetic acid solution to fully dissolve the gas and absorb benzene compounds such as toluene in the gas. Installing the acetic acid storage tank outside the baking oven can effectively reduce the temperature of the acetic acid, reduce evaporation, and make full use of the acetic acid. However, the acetic acid storage tank cools the internal acetic acid solution through an externally spirally wound cooling copper pipe. The cooling copper pipe is located on the outside, and the cooling effect is limited. At the same time, the acetic acid storage tank, after removing harmful gases such as toluene and benzene compounds, is directly sent back to the baking oven. The temperature difference between this gas and the gas inside the baking oven is large, which affects the drying of the electromagnetic wire coating. Therefore, we propose an electromagnetic wire coating baking device. Utility Model Content

An extension pipe 554 is fixedly connected to the upper end of the end cap of the acetic acid storage tank 557. The lower end of the extension pipe 554 is located inside the lower end of the acetic acid storage tank 557. The upper end of the extension pipe 554 is fixedly connected to the lower end of the first air supply pipe 53. A feeding port 551 is provided on the upper end of the end cap of the acetic acid storage tank 557. The explosion-proof component 55 also includes a water inlet 552, a cooling spiral tube 555, and heat dissipation fins 556. The cooling spiral tube 555 is fixedly connected to the bottom wall of the acetic acid storage tank 557. The outlet of the cooling spiral tube 555 passes through a through hole at the lower end of the bottom wall of the acetic acid storage tank 557. A water inlet 552 is provided at the upper end of the cooling spiral tube 555. The upper end of the heat sink passes through the through hole 2 at the upper end of the end cap of the acetic acid storage tank 557.

The liquid level sensor 553 is bidirectionally electrically connected to the microcontroller 3. The heating component 57 includes a heating tank 571, a dry-burning heating tube 572, and a tank cover 573. The heating tank 571 is placed on the upper left side of the bracket 4. The upper end of the heating tank 571 is bolted to the tank cover 573. Evenly distributed dry-burning heating tubes 572 are fixedly connected to the edge of the tank cover 573. All 572 are located inside the heating tank 571. The end cap of the acetic acid storage tank 557 and the lower end of the heating tank 571 are connected by a connecting pipe 56. The middle part of the tank cover 573 is connected to the upper surface of the oven 1 by a return gas pipe 54. The input end of the dry-burning heating tube 572 is electrically connected to the output end of the microcontroller 3. During drying, the paint film on the surface of the electromagnetic wire solidifies and releases vaporized toluene and other benzene compounds. The air pump 51 draws gas from inside the oven 1 through the exhaust pipe 52 and sends it into the acetic acid storage tank 557 through the first gas supply pipe 53. The high-temperature gas mixed with toluene and other benzene compounds enters the acetic acid storage tank 557 from the extension pipe 554 and mixes with the acetic acid solution. The outlet of the extension pipe 554 is located at the lower end of the acetic acid storage tank 557.To facilitate thorough mixing of the high-temperature gas containing toluene and other benzene compounds with the glacial acetic acid solution, which is readily soluble in the glacial acetic acid solution, an external water pump draws cold water from the water tank and supplies it into the water inlet 552 of the cooling spiral tube 555 (the cooling spiral tube 555 is a nickel-based alloy spiral tube, which is corrosion-resistant; the water inlet 552 and outlet of the cooling spiral tube 555 are fixedly connected by welding to prevent leakage). The glacial acetic acid solution exchanges heat with the cold water through the cooling spiral tube 555, thus cooling the glacial acetic acid solution. The cold water inside the cooling spiral tube 555 flows from the cooling spiral tube... The water outlet of the spiral tube 555 returns to the water tank for recycling. The level sensor 553 detects changes in the acetic acid solution level and feeds back to the microcontroller 3. When the acetic acid solution is too low, the worker injects more acetic acid solution through the feed port 551. Simultaneously, the heat dissipation fins 556 increase the contact area between the acetic acid storage tank 557 and the outside environment, enhancing heat dissipation. Gases containing toluene and other benzene compounds enter the lower end of the heating tank 571 through the connecting pipe 56. The dry-burning heating tube 572 inside the heating tank 571 heats the gas, and the heated air then returns to the drying oven 1 through the return gas pipe 54.

[0019] The oven 1 also includes a microcontroller 3, which is located on the right side of the oven 1. The input of the microcontroller 3 is electrically connected to an external power source, and the inputs of the heating plate 2 and the air pump 51 are both electrically connected to the output of the microcontroller 3.

[0020] The working principle of the electromagnetic wire coating baking equipment provided by this utility model is as follows: Before using this electromagnetic wire coating baking equipment, the second air supply pipe 7 is connected to an external air pump, and the exhaust pipe 6 is connected to the exhaust gas treatment equipment. Temperature sensors are evenly distributed inside the oven 1, and each temperature sensor is bidirectionally connected to the microcontroller 3 to detect the temperature at various locations inside the oven 1. A pressure gauge is installed at the top of the oven 1 to detect the internal air pressure. The electromagnetic wire coil to be dried is placed inside the oven 1 using a hanger. The microcontroller 3 activates the heating plate 2 and various electrical components for heating and drying. During drying, the electric... The varnish film on the surface of the magnetic wire solidifies and releases vaporized toluene and other benzene compounds. The air pump 51 draws gas from inside the oven 1 through the extraction pipe 52 and sends it into the glacial acetic acid storage tank 557 through the first air supply pipe 53. The high-temperature gas mixed with toluene and other benzene compounds enters the glacial acetic acid storage tank 557 through the extension pipe 554 and mixes with the glacial acetic acid solution. The outlet of the extension pipe 554 is located at the lower end of the glacial acetic acid storage tank 557, facilitating thorough mixing of the high-temperature gas with toluene and other benzene compounds with the glacial acetic acid solution. Toluene and other benzene compounds are easily soluble in glacial acetic acid solution. Simultaneously, an external water pump draws cold water from the water tank and directs it towards the cooling spiral pipe 555. Cold water is introduced through inlet 552 (the cooling spiral tube 555 is a nickel-based alloy spiral tube, which is corrosion-resistant; the inlet 552 and outlet of the cooling spiral tube 555 are fixedly connected by welding to prevent leakage). The glacial acetic acid solution exchanges heat with the cold water through the cooling spiral tube 555, thus cooling the solution. The cold water inside the cooling spiral tube 555 returns to the water tank through the outlet for recycling. The level sensor 553 detects changes in the glacial acetic acid solution level and feeds it back to the microcontroller 3. When the glacial acetic acid solution is too low, the worker injects more solution through inlet 551, while the heat dissipation fins... Plate 556 increases the contact area between the glacial acetic acid storage tank 557 and the outside world, enhancing heat dissipation. Gases that have removed toluene and other benzene compounds enter the lower end of the heating tank 571 through the connecting pipe 56. The dry-burning heating tube 572 inside the heating tank 571 heats the gas. The heated air then returns to the oven 1 through the return air pipe 54. After the electromagnetic wire drying is completed, the solenoid valves of the exhaust pipe 6 and the second air supply pipe 7 are opened. The external air pump sends in external air through the second air supply pipe 7, and the gas inside the oven 1 is discharged from the exhaust pipe 6, realizing gas replacement inside the oven 1 and preventing workers from inhaling harmful gases when opening the oven 1.

[0021] It is worth noting that the microcontroller 3 disclosed in the above embodiments can be an STM8L101F3U6ATR microcontroller, the air pump 51 can be a D066M high-temperature resistant air pump, the liquid level sensor 553 can be a JKM-JY corrosion-resistant liquid level transmitter, and the dry-burning heating tube 572 can be a BT-GDQ-15KW dry-burning heating tube. The microcontroller 3 controls the operation of the air pump 51, the liquid level sensor 553, and the dry-burning heating tube 572 using methods commonly used in the prior art.
