Description

Technical Field

[0001] This application relates to the field of air purification technology for spray painting booths for wooden furniture panels, and in particular to a spray painting booth for wooden furniture panels. Background Technology

[0002] Spray painting booths, as key equipment in industries such as wood furniture manufacturing, are widely used for spraying and baking workpiece surfaces. While improving product quality and appearance, they also place higher demands on the working environment. In recent years, with increasing environmental awareness and concern for operator health, pollution control technology for spray painting booths has gradually become a focus of industry research. How to effectively handle the dust and volatile organic compounds (VOCs) generated during the spray painting process not only affects the company's production efficiency but also directly impacts environmental protection and employee health. Currently, to solve the dust pollution problem in spray painting booths, the industry typically uses exhaust fans in conjunction with filters. Specifically, conventional methods include: extracting dust-laden air using exhaust fans and guiding it to a filtration device for purification; using multi-layer filters to filter dust in the air in stages; or maintaining normal equipment operation by regularly replacing or cleaning the filters. In addition, some solutions attempt to combine mechanical vibration or airflow backflushing to reduce filter clogging. However, these methods have certain limitations in practical applications. In existing technologies, although filtration can effectively remove dust from the air, filters are prone to clogging due to dust adsorption, leading to a decrease in filtration efficiency. Especially after prolonged use, cleaning and maintaining the filters becomes complex and time-consuming, severely impacting the operating efficiency and purification effect of the spray booth. Therefore, there is an urgent need for a technical solution that can automatically clean the filters and prevent clogging to improve the dust handling capacity of the spray booth. Utility Model Content

[0003] The purpose of this application is to overcome the above-mentioned technical problems and provide a spray painting booth for wooden furniture panels.

[0004] A spray painting booth for wooden furniture panels includes a booth body with two protective doors hinged to one side. A dust collection device is connected to the booth body, comprising an exhaust duct, an exhaust fan connected to the exhaust duct, and filter cartridges connected to the exhaust duct. The filter cartridges contain a first filter cartridge and a second filter cartridge, with the first filter cartridge located inside the second filter cartridge. The mesh size of the first filter cartridge is larger than that of the second filter cartridge. A cleaning component is installed within the filter cartridges to clean both the first and second filter cartridges. By adopting this technical solution, when the user operates the exhaust fan, a negative pressure is created within the exhaust duct, drawing air from the booth into the filter cartridges. The air passes sequentially through the first and second filter cartridges, filtering impurities and dust from the air. The cleaning component automatically cleans the first and second filter cartridges, preventing clogging and ensuring the purification effect of the filter cartridges is not affected. Preferably, the cleaning component includes multiple scraper rods disposed inside the filter cartridge. The scraper rods abut against the inner wall of the first filter cartridge, and a drive component is connected to the scraper rods to drive their rotation. By adopting the above technical solution, when the user uses the filter cartridge, the drive component drives the scraper rods to rotate along the inner wall of the first filter cartridge. The scraper rods scrape off the impurities and dust adsorbed inside the first filter cartridge, reducing clogging of the filter cartridge's mesh and facilitating dust collection. Preferably, the drive component includes a drive motor. The output shaft of the drive motor extends into the filter cartridge. A positioning ring is fixedly connected to the output shaft of the drive motor. Support rods corresponding to the scraper rods are fixedly connected to the positioning ring. The support rods are evenly spaced along the circumference of the positioning ring, and the scraper rods are fixedly connected to the support rods, perpendicular to the support rods. By adopting the above technical solution, when the user uses the filter cartridge, the drive motor is powered on, which drives the support rods to rotate. The support rods then drive the scraper rods to slide, scraping off the dust from the inner wall of the first filter cartridge. Preferably, a limiting box is fixedly connected to the support rod, and multiple buffer springs are fixedly connected inside the limiting box. The end of the buffer spring away from the limiting box is fixedly connected to the scraper rod. By adopting the above technical solution, when the scraper rod scrapes material against the inner wall of the first filter cylinder during user operation, the pressure of the buffer springs ensures that the scraper rod always abuts against the inner wall of the first filter cylinder. Furthermore, when encountering hard impurities on the inner wall of the first filter cylinder, the scraper rod is also cushioned. Preferably, a baffle is fixedly connected to one side of the scraper rod extending into the limiting box. The baffle's size is larger than the limiting groove diameter of the limiting box. By adopting the above technical solution, the baffle can limit the scraper rod during user operation, preventing it from detaching from the limiting box. Preferably, a fixing rod is fixedly connected to the support rod, extending between the first and second filter cylinders. A first brush is fixedly connected to the side of the fixing rod closest to the first filter cylinder, and the first brush abuts against the outer wall of the first filter cylinder. By adopting the above technical solution, when the user uses the device, the drive motor drives the support rod to rotate, and the support rod drives the first brush to rotate. The first brush can clean the first filter cartridge and reduce the clogging of the first filter cartridge mesh.Preferably, a second brush is fixedly connected to the side of the fixing rod near the first filter cartridge, and the second brush abuts against the inner wall of the second filter cartridge. By adopting the above technical solution, when the user uses the filter cartridge, the drive motor drives the support rod to rotate, the support rod drives the first brush to rotate, and the second brush can clean the second filter cartridge, reducing clogging of the filter cartridge mesh. Preferably, a conical collection bin is fixedly connected to the bottom of the filter cartridge corresponding to the position of the first filter cartridge, a discharge pipe is fixedly connected to the bottom of the collection bin, and an annular collection trough is fixedly connected to the outside of the collection bin, with a discharge pipe fixedly connected to the collection trough. By adopting the above technical solution, when the user uses the filter cartridge, impurities and dust scraped off by the first filter cartridge fall into the collection bin and are collected, then discharged outwards through the discharge pipe. Dust scraped off by the first and second brushes falls into the collection trough and is finally discharged outwards through the discharge pipe. Attached Figure Description

[0011] The inventors of this application have discovered that spray booths, as key equipment in industries such as wood furniture manufacturing, are widely used for spraying and baking workpiece surfaces. While improving product quality and appearance, they also place higher demands on the working environment. In existing technologies, although filtration can effectively remove dust from the air, the filters are prone to clogging due to dust adsorption, leading to a decrease in filtration efficiency. Especially after prolonged use, cleaning and maintenance of the filters become complex and time-consuming, seriously affecting the operating efficiency and purification effect of the spray booth. Therefore, this application mainly adopts a spray booth solution for wood furniture panels, achieving automatic filter cartridge cleaning and preventing clogging, thereby improving the dust handling capacity of the spray booth. A spray booth for wood furniture panels, as described above. Figure 1 and Figure 2 The system includes a housing 1, with two protective doors 11 hinged to one side. A dust collection device 2 is connected to the housing 1. The dust collection device 2 consists of an exhaust pipe 21, an exhaust fan 211, a filter cartridge 22, a first filter cartridge 23, a second filter cartridge 24, and a cleaning assembly 25. The exhaust pipe 21 connects the housing 1 and the filter cartridge 22, and the exhaust fan 211 is mounted on the exhaust pipe 21 to extract air containing dust. The filter cartridge 22 contains a first filter cartridge 23 and a second filter cartridge 24 for staged filtration. The first filter cartridge 23 is located inside the second filter cartridge 24 and has a larger mesh size for initial filtration of larger particles; the second filter cartridge 24 has a smaller mesh size for further filtration of fine dust particles. The filter cartridge 22 also contains a cleaning assembly 25, which is responsible for automatically cleaning the first filter cartridge 23 and the second filter cartridge 24 to prevent clogging.

[0012] Reference Figure 3 and Figure 4 The cleaning component 25 includes a drive motor 251. The output shaft of the drive motor 251 extends into the filter cartridge 22, and a positioning ring 252 is fixedly connected to it. Multiple support rods 253 are fixedly connected to the positioning ring 252, and each support rod 253 is equipped with a scraper 254. These scraper rods 254 are disposed inside the filter cartridge 22, abutting against the inner wall of the first filter cartridge 23. The support rods 253 are evenly spaced along the circumference of the positioning ring 252, and the scraper rods 254 are fixedly connected to the support rods 253 and perpendicular to them. When the drive motor 251 is energized, its output shaft rotates, causing the positioning ring 252 to rotate, thereby causing the support rods 253 and scraper rods 254 to rotate together. During rotation, the scraper rods 254 can scrape off impurities and dust adsorbed on the inner wall of the first filter cartridge 23, reducing clogging of the mesh of the first filter cartridge 23 and facilitating dust collection.

[0013] A limit box 255 is also fixedly connected to the support rod 253. Multiple buffer springs 2551 are fixedly connected inside the limit box 255, with the end of each buffer spring 2551 away from the limit box 255 fixedly connected to the scraper rod 254. This design ensures that when the scraper rod 254 scrapes material from the inner wall of the first filter cartridge 23, the pressure of the buffer springs 2551 keeps the scraper rod 254 in contact with the inner wall of the first filter cartridge 23. Furthermore, when encountering abnormal conditions such as hard impurities on the inner wall of the first filter cartridge 23, the buffer springs 2551 can also cushion the scraper rod 254, protecting it and the entire cleaning assembly 25 from damage. (Refer to...) Figure 5 The scraper 254 extends to one side of the limiting box 255 and is fixedly connected to a baffle 2552. The size of the baffle 2552 is larger than the diameter of the limiting groove of the limiting box 255. This design can effectively prevent the scraper 254 from detaching from the limiting box 255 and ensure the stable operation of the cleaning assembly 25.

[0014] A fixing rod 256 is also fixedly connected to the support rod 253, extending between the first filter cartridge 23 and the second filter cartridge 24. A first brush 257 is fixedly connected to the side of the fixing rod 256 near the first filter cartridge 23, and the first brush 257 abuts against the outer wall of the first filter cartridge 23. When the drive motor 251 drives the support rod 253 to rotate, the support rod 253 drives the first brush 257 to rotate, and the first brush 257 can clean the first filter cartridge 23, further reducing the clogging of the mesh of the first filter cartridge 23.

[0015] A second brush 258 is fixedly connected to the side of the fixing rod 256 near the second filter cartridge 24, and the second brush 258 abuts against the inner wall of the second filter cartridge 24. When the drive motor 251 drives the support rod 253 to rotate, the support rod 253 drives the second brush 258 to rotate, and the second brush 258 can clean the second filter cartridge 24, reducing the clogging of the mesh of the second filter cartridge 24. A conical collection bin 221 is fixedly connected to the bottom of the filter cartridge 22 at the position corresponding to the first filter cartridge 23, and a discharge pipe 223 is fixedly connected to the bottom of the collection bin 221. An annular collection trough 222 is fixedly connected to the outside of the collection bin 221 of the filter cartridge 22, and a discharge pipe 224 is fixedly connected to the collection trough 222. The purpose of this design is that the impurities and dust scraped off by the first filter cartridge 23 fall into the collection bin 221 and are collected, and then discharged outward through the discharge pipe 223; the dust scraped off by the first brush 257 and the second brush 258 falls into the collection trough 222 and is finally discharged outward through the discharge pipe 224, thereby achieving effective collection and discharge of dust.

[0016] By incorporating the cleaning component 25, automatic cleaning of the first filter cartridge 23 and the second filter cartridge 24 is achieved. The scraper 254 effectively removes dust from the inner wall of the first filter cartridge 23 during rotation, while the first brush 257 and the second brush 258 clean the outer wall of the first filter cartridge 23 and the inner wall of the second filter cartridge 24, respectively. The design of the collection bin 221 and collection trough 222 effectively collects and discharges the scraped dust, preventing filter cartridge clogging and improving the dust handling capacity of the spray booth. This overall design not only improves the equipment's operating efficiency but also reduces manual maintenance workload, significantly enhancing the practicality and environmental performance of the spray booth.

[0017] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
