Furthermore, during the waste gas treatment process, impurities in the waste gas easily clog the equipment, and existing filter structures are cumbersome to clean and replace, affecting the normal operation and maintenance efficiency of the equipment. Therefore, we need to upgrade and transform existing technologies. Utility Model Content

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figure 1 As shown in Figure 5, this embodiment provides a waste heat recovery device for powder coating curing oven exhaust gas, including a device body 1. The device body 1 contains a powder coating curing oven 2, an exhaust gas pipe 3, a tubular heat exchanger 4, a mounting frame 5, a connecting pipe 6, a processing box 7, a processing pipe 8, an inlet pipe 9, a heating pipe 10, a hot air blower 11, a controller 12, a support frame 13, a temperature sensor 14, a filter screen 15, a first inspection plate 16, a second inspection plate 17, a mounting plate 18, a handle 19, a mounting groove 20, and a strong magnet 21. The powder coating curing oven 2 is connected to the exhaust gas pipe 3... A tubular heat exchanger 4 is connected and mounted on a mounting bracket 5. The tubular heat exchanger 4 is connected to a processing box 7 via a connecting pipe 6. A processing pipe 8 and an air inlet pipe 9 are provided on the processing box 7. A heating pipe 10 and a hot air blower 11 are provided on the processing pipe 8. A temperature sensor 14 is provided on the processing pipe 8. A filter screen 15 is provided inside the processing box 7. Inspection plate one 16 and inspection plate two 17 are provided on the processing box 7. A mounting plate 18 is provided on the filter screen 15. A mounting groove 20 is provided on the processing box 7. A strong magnet 21 is provided inside the mounting groove 20.

[0026] Preferably, the tube heat exchanger 4 is a finned tube heat exchanger. Compared with ordinary tube heat exchangers 4, the use of finned tube heat exchangers increases the heat exchange area, which can more efficiently absorb the heat in the exhaust gas of the powder coating curing oven 2, improve the waste heat recovery efficiency, thereby improving energy utilization and reducing the company's energy costs. The temperature sensor 14 is electrically connected to the controller 12, and the controller 12 is electrically connected to the heating tube 10 and the hot air blower 11, which can ensure the temperature of the hot air output in the treatment tube 8 is stable, making the waste heat utilization process more intelligent and automated, improving the stability and reliability of waste heat reuse, and meeting the requirements for hot air temperature under different working conditions. The inspection plate 16 and the inspection plate 2 17 are connected to the treatment box 7 by hinges, which facilitates opening and closing. When inspecting, maintaining, cleaning or replacing the inside of the treatment box 7, there is no need for complicated disassembly operations. The inspection plate can be quickly opened to perform the corresponding operations, which improves the convenience and efficiency of equipment maintenance.

[0027] Preferably, the mounting plate 18 and the strong magnet 21 are attracted to each other, making the installation and removal of the filter screen 15 extremely convenient. When cleaning or replacing the filter screen 15, it can be removed directly. During installation, it will automatically attract and fix itself when close to the strong magnet 21. Compared with traditional bolt connections, this reduces cumbersome operation steps, shortens maintenance time, and ensures continuous operation of the equipment. The hot air blower 11 is connected to the controller 12 on the side, and a support frame 13 is installed below the controller 12. By setting the support frame 13, the stability of the controller 12 is increased, ensuring the safety of the controller 12 during operation. A handle 19 is fixedly installed on the top of the mounting plate 18. The mounting plate 18 is installed between the first maintenance plate 16 and the second maintenance plate 17. The handle 19 makes it convenient for users to pull and put the mounting plate 18 in and out, increasing the practicality and convenience of the device.

[0028] The working principle and process of this utility model are as follows: During operation, the powder coating curing oven 2 generates high-temperature waste gas during the powder coating curing process of the workpiece. The high-temperature waste gas enters the tubular heat exchanger 4 through the waste gas pipe 3. In the tubular heat exchanger 4, the high-temperature waste gas exchanges heat with the heat exchange medium inside the pipe. The heat of the waste gas is absorbed, and the temperature decreases. After heat exchange, the waste gas enters the treatment box 7 through the connecting pipe 6. Inside the treatment box 7, a filter screen 15 is installed to filter impurities in the waste gas. Part of the filtered waste gas is discharged through the air inlet pipe 9, and the other part passes through the treatment pipe 8. In the treatment pipe 8, the hot air blower 11 blows air in, and the heating tube 10 provides auxiliary heating to the air. The temperature sensor 14 monitors the temperature inside the treatment pipe 8 in real time and transmits the temperature signal to the controller 12. The controller 12 controls the working status of the heating tube 10 and the hot air blower 11 according to the temperature signal to ensure a stable output hot air temperature. The heated air can be reused, for example, for preheating workpieces or workshop heating. When the filter screen 15 needs to be cleaned or replaced, open the inspection plate 17 by using the handle 19. Since the mounting plate 18 and the strong magnet 21 attract and cooperate with each other, the filter screen 15 can be taken out from the processing box 7. After cleaning or replacing, insert the filter screen 15 into the mounting slot 20 and fix it by attracting and fixing it with the strong magnet 21.
