Description
Technical Field
[0001] The present invention relates to the technical field of exhaust air filtration, and particularly to an exhaust air filtration device for a painting production line. Background Art
[0002] In a painting production line, paint mist, volatile organic compounds (VOCs), and other harmful particulate matters in the air not only pose a threat to the health of workers but also pollute the atmospheric environment. To ensure the safety and cleanliness of the working environment and effectively control air pollution, an exhaust air filtration device is usually used to purify the air. These devices capture and remove harmful substances in the exhaust gas, reducing the negative impact on the environment and are an essential part of environmental protection engineering construction.
[0003] However, the existing exhaust air filtration devices have some deficiencies. First, the traditional intake frame design often fails to fully optimize the air flow path, resulting in a large resistance and vortex phenomenon when air enters the device, reducing the overall filtration efficiency. Second, the process of replacing the filter plate is relatively complex, usually requiring the disassembly of multiple components, increasing the maintenance difficulty and time cost. Finally, some exhaust air filtration devices lack a convenient moving and fixing mechanism, making it difficult to adapt to the needs of different working environments and restricting their flexibility and application scope.

One side of the filter frame is fixedly connected with an intake frame through two fixing mechanisms. An installation slot is opened on one side of the filter frame, a filter plate is inserted into the installation slot, a plugging mechanism for fixing the filter plate is arranged on the filter frame, and a fan is installed on one side of the filter plate inside the filter frame.
[0006] As a further improvement of the present invention, the limiting mechanism includes a limiting block provided on one side of the support frame. A limiting groove is formed on one side of the insertion block. One end of the limiting block penetrates through the insertion slot and is inserted into the limiting groove. A through groove is formed at the other end of the limiting block. Two mounting plates are fixedly connected to one side of the support frame. The lower ends of the two mounting plates are both fixedly connected with a first spring. The other ends of the two first springs are fixedly connected to the same pulling handle.

[0007] As a further improvement of the present invention, the fixing mechanism includes a fixing block fixedly connected to one side of the air inlet frame. A connecting block is fixedly connected to one side of the filter frame. A rectangular block is fixedly connected to the side of the fixing block close to the connecting block.

A threaded hole is formed on one side of the rectangular block. A bolt is provided on one side of the connecting block. One end of the bolt penetrates through the rectangular groove and is threadedly connected to the threaded hole.
[0008] As a further improvement of the present invention, the insertion mechanism includes a U-shaped frame fixedly connected to one side of the filter plate. A fixing frame fixedly connected to the filter frame is provided on one side of the U-shaped frame. A moving groove is formed on the fixing frame.

[0009] As a further improvement of the present invention, the air inlet frame is of a conical structure, which can optimize the air flow path.
[0010] As a further improvement of the present invention, a connecting plate is fixedly connected to the end of the filter frame far from the air inlet frame. A plurality of connecting holes are circumferentially formed on the connecting plate.
[0011] As a further improvement of the present invention, a fixing collar is fixedly sleeved on the filter frame. Two lifting holes are formed at the upper end of the fixing collar.
[0012] As a further improvement of the present invention, four universal wheels are fixedly connected to the lower end of the base. Each universal wheel is equipped with its own locking mechanism.

The conical structure design enables air to flow more smoothly into the pre-filter module, reducing energy loss and noise generation. Through this design, not only can the resistance when air enters the device be reduced, but also vortex phenomena can be effectively reduced, thereby improving the overall filtration efficiency and ensuring the efficient operation of the air treatment system.
[0016]

The plug-in mechanism in the present invention includes components such as a U-shaped frame, a fixed frame, a moving block, and a pulling ring. When it is necessary to replace or clean the filter plate, simply pull the pulling ring to disengage the moving block from the U-shaped frame, and the filter plate can be easily removed. The whole process is simple and fast, greatly reducing the maintenance difficulty and time cost, and improving the operability and maintenance efficiency of the equipment.
[0017]

These universal wheels are made of high-quality materials, have good wear resistance and load-bearing capacity, can adapt to different ground conditions, and ensure the stable and reliable movement of the equipment. In addition, two lifting holes are provided on the support frame for convenient lifting and handling of the equipment. Through these designs, the equipment can be flexibly moved and installed in different working environments, greatly improving its flexibility and application range, and meeting diverse production needs.
[0018]

In addition, the rectangular block in the fixing mechanism fits tightly with the rectangular groove and is reinforced by bolts to ensure the firm connection between the air inlet frame and the filter frame. These designs not only prevent loosening or displacement during use, but also improve the overall stability and safety of the equipment.

Detailed implementation manners
[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.
[0023] Figures 1-6 , an exhaust air filtering device for a painting production line, including a base 1, four universal wheels 3 are fixedly connected to the lower end of the base 1, and each universal wheel 3 is equipped with its own locking mechanism to facilitate the movement and fixation of the device. These universal wheels 3 are made of high-quality materials, have good wear resistance and load-bearing capacity, can adapt to different ground conditions, and ensure the stable and reliable movement of the device. A support frame 2 is fixedly connected to the upper end of the base 1. The support frame 2 is made of a strong metal material, has high strength and stability, and can withstand a large weight and external impact force. Two plugging slots 21 are opened at the upper end of the support frame 2. A filter frame 4 is provided above the support frame 2. A fixed collar 6 is fixedly sleeved on the filter frame 4, and two lifting holes 7 are opened at the upper end of the fixed collar 6 to facilitate the lifting of the device.
[0024] At the lower end of the filter frame 4, two plug-in blocks 20 are fixedly connected. The sizes of the two plug-in blocks 20 respectively match the internal sizes of the two plug-in slots 21 to achieve precise positioning and installation. The two plug-in blocks 20 are respectively connected to the two plug-in slots 21 through a limiting mechanism to ensure that the filter frame 4 will not loosen or shift during use. The limiting mechanism includes a limiting block 22 arranged on one side of the support frame 2. A limiting slot 33 is opened on one side of the plug-in block 20 to form a stable mechanical connection. One end of the limiting block 22 penetrates through the plug-in slot 21 and is inserted into the limiting slot 23. A through slot 23 is opened at the other end of the limiting block 22. Two mounting plates 25 are fixedly connected to one side of the support frame 2. The lower ends of the two mounting plates 25 are both fixedly connected with a first spring 26. The other ends of the two first springs 26 are fixedly connected to the same pulling handle 27. The upper end of the pulling handle 27 is fixedly connected with a plug-in plate 24. One end of the plug-in plate 24 penetrates through the through slot 23 and extends outwards. When it is necessary to disassemble the filter frame 4, just pull the pulling handle 27 to easily pull out the plug-in plate 24 from the through slot 23.
[0025] One side of the filter frame 4 is fixedly connected with an air inlet frame 8 through two fixing mechanisms. The air inlet frame 8 is of a conical structure, which can optimize the air flow path, reduce the resistance and eddy current phenomenon when air enters the device, and improve the overall filtration efficiency. The fixing mechanism includes a fixing block 9 fixedly connected to one side of the air inlet frame 8. A connecting block 10 is fixedly connected to one side of the filter frame 4. A rectangular block 15 is fixedly connected to the side of the fixing block 9 close to the connecting block 10. A rectangular groove 14 is opened on the side of the connecting block 10 close to the rectangular block 15. The size of the rectangular block 15 matches the internal size of the rectangular groove 14, so that the rectangular block 15 can be tightly inserted into the rectangular groove 14 to ensure a firm connection. The rectangular block 15 is inserted into the rectangular groove 14. A threaded hole 17 is opened on one side of the rectangular block 15. A bolt 16 is arranged on one side of the connecting block 10. One end of the bolt 16 penetrates through the rectangular groove 14 and is threadedly connected to the threaded hole 17, further enhancing the stability of the connection. A connecting plate 5 is fixedly connected to the end of the filter frame 4 far from the air inlet frame 8. A plurality of connecting holes 11 are circumferentially opened on the connecting plate 5. These connecting holes 11 can be used to connect with other devices or pipelines, facilitating system integration and expansion to form a complete air treatment system.
[0026] A mounting groove 18 is provided on one side of the filter frame 4, and a filter plate 19 is inserted in the mounting groove 18. A plug-in mechanism for fixing the filter plate 19 is provided on the filter frame 4 to ensure that the filter plate 19 will not loosen or fall off during operation. The plug-in mechanism includes a U-shaped frame 28 fixedly connected to one side of the filter plate 19, and a fixing frame 29 fixedly connected to the filter frame 4 is provided on one side of the U-shaped frame 28. A moving groove 30 is provided on the fixing frame 29, and a moving block 13 is slidably provided in the moving groove 30. One end of the moving block 13 is inserted through the U-shaped frame 28 and extends outward, and the other end of the moving block 13 is fixedly connected to a pull ring 12, the upper and lower ends of the moving block 13 are fixedly connected with support plates 32, the same side of the two support plates 32 is fixedly connected with a second spring 31, the other ends of the two second springs 31 are fixedly connected to the side wall of the fixed frame 29, when the filter plate 19 needs to be replaced, only the pulling ring 12 is needed to disengage the moving block 13 from the U-shaped frame 28, and the filter plate 19 can be easily taken out. The whole process is simple and fast. A fan 34 is installed on one side of the filter plate 19 in the filter frame 4. The fan 34 is responsible for driving the air flow to ensure that the air can pass through each filter layer smoothly and finally discharge clean air.
[0027] When the present invention is used, first, ensure that the four universal wheels 3 under the base 1 are in a locked state to ensure the stability of the device during use. The air intake frame 8 is connected to one side of the filter frame 4 through two fixing mechanisms. The conical structure of the air intake frame 8 can optimize the air flow path and reduce the resistance and eddy current phenomenon when entering the device. Next, align the plug-in block 20 at the lower end of the filter frame 4 with the plug-in slot 21 on the support frame 2, and insert the limiting mechanism to ensure that the filter frame 4 is firmly installed on the support frame 2. This is then connected to other equipment or pipelines through multiple connecting holes 11 on the connecting plate 5 to form a complete air treatment system. Then, turn on the fan 34 to allow air to pass through the filter layer smoothly. If the filter plate 19 needs to be replaced or cleaned, just pull the pull ring 12 to disengage the moving block 13 from the U-shaped frame 28, and the filter plate 19 can be easily removed. When the filter frame 4 needs to be hoisted, the disassembly can be completed by pulling the pull handle 27 and pulling the plug plate 24 out of the through groove 23. At this time, it is connected to the two hoisting holes 7 through the hoisting rope, and at the same time connected to other equipment or pipelines through the multiple connecting holes 11 on the connecting plate 5, so that it can be hoisted to form a complete air treatment system.
