It should be understood that the specific embodiments described herein are only used to explain the present disclosure and are not used to limit the present disclosure.

It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting the present application.

[0047] The following further describes the present application in detail with reference to the accompanying drawings. See Figures 1 to 7 description.

[0048] As Figures 1 to 4 shown, the present application provides a paint mist tail gas treatment device (hereinafter referred to as the treatment device), which is used for filtering the paint mist tail gas so that the treated paint mist tail gas can meet the emission standards and avoid environmental pollution.

[0049] Specifically, the treatment device includes a feeding mechanism, a filtering mechanism 7 and a filter cartridge 2; a space for accommodating the paint mist tail gas is provided inside the filter cartridge 2, as Figure 1 , Figure 2As shown, support feet are provided at the bottom of the filter cartridge 2 to lift and support the filter cartridge 2. An air inlet 4 is provided on the lower side wall of the filter cartridge 2, and an air outlet 5 is provided on the upper end face of the filter cartridge 2, that is, the air outlet 5 is located above the air inlet 4. Among them, an exhaust fan is provided on one side of the air outlet 5 to draw the paint mist exhaust gas from the direction of the air inlet 4 to the direction of the air outlet 5; as Figure 1 shown, the filtering mechanism 7 is arranged inside the filter cartridge 2, and the filtering mechanism 7 is located between the air outlet 5 and the air inlet 4. That is, in the vertical direction, the air inlet 4, the filtering mechanism 7, and the air outlet 5 are arranged in sequence from bottom to top. The filtering mechanism 7 is provided with a filter cotton belt 3. The filter cotton belt 3 is a multi-layer structure with good filtering effect. When the exhaust fan operates, during the process that the paint mist exhaust gas flows from the air inlet 4 to the air outlet 5, it will pass through the filtering mechanism 7, and the filter cotton belt 3 in the filtering mechanism 7 can better adsorb substances such as organic dust in the paint mist exhaust gas, so that the paint mist exhaust gas flowing out from the air outlet 5 has been filtered and processed to meet the environmental protection emission standards and then be discharged outward.

[0050] As Figure 1 、 Figure 3 shown, the filtering mechanism 7 includes a filter net. The filter net is connected to the inner side wall of the filter cartridge 2. The filter net is made of a metal material. The filter net is divided into an upper filter net 9 and a lower filter net 10. The upper filter net 9 is arranged above the lower filter net 10. There is a space for accommodating the filter cotton belt 3 between the upper filter net 9 and the lower filter net 10. The lower filter net 10 is used to support the filter cotton belt 3, and the upper filter net 9 is used to limit the upward movement of the filter cotton belt 3 under the action of the fan; the distance between the upper filter net 9 and the lower filter net 10 is not much different from the thickness of the filter cotton belt 3, so that the filtering mechanism 7 can better clamp the filter cotton belt 3.

[0051] In this embodiment, as Figure 1 shown, a feed inlet 28 and a discharge outlet 29 are provided on the opposite side walls of the filter cartridge 2. The filter cotton belt 3 outside the filter cartridge 2 enters the filtering mechanism 7 from the feed inlet 28, and then is conveyed from the discharge outlet 29 out of the filtering mechanism 7 to the outside of the filter cartridge 2; the feeding mechanism is connected to the outer side wall of the filter cartridge 2, and the feeding mechanism is arranged on the same side as the discharge outlet 29. The feeding mechanism is used to pull the filter cotton belt 3 to move. The filter cotton belt 3 moves from the feed inlet 28 to the discharge outlet 29 direction to realize the replacement of the filter cotton belt 3 in the filtering mechanism 7. The feeding mechanism is arranged below the filtering mechanism 7 to facilitate pulling the filtering mechanism 7.

[0052] As Figure 1As shown in the figure, the feeding mechanism is arranged on the same side as the discharge port 29. A reel 8 is provided on one side of the feeding port 28 for placing the rolled filter cotton belt 3. When the feeding mechanism pulls the filter cotton belt 3, the reel 8 rotates counterclockwise to release the filter cotton belt 3. The filter cotton belt 3 enters the filtering mechanism 7 from the feeding port 28, then moves from the filtering mechanism 7 to the discharge port 29, and then falls into the placement box below the feeding mechanism after passing through the feeding mechanism.

[0053] As Figures 1 to 4 shown in the figure, the feeding mechanism includes a driving component 20 and a reel component 21. The driving component 20 is fixedly connected to the filter cylinder 2, the reel component 21 is rotatably connected to the filter cylinder 2, the driving component 20 is connected to the reel component 21 to drive the reel component 21 to rotate, and the filter cotton belt 3 passes between the reel components 21, that is, the filter cotton belt 3 is in contact with the reel component 21, so as to pull the filter cotton belt 3.

[0054] Specifically, as Figures 1 to 4 shown in the figure, the reel component 21 includes a first reel 22 and a second reel 23. The first reel 22 and the second reel 23 are arranged in parallel at intervals on the same horizontal plane. The second reel 23 is located outside the first reel 22. The distance between the first reel 22 and the second reel 23 is just enough for the filter cotton belt 3 to pass through; both ends of the first reel 22 are rotatably connected to the filter cylinder 2, and both ends of the second reel 23 are rotatably connected to the filter cylinder 2; among them, the first reel 22 is connected to the driving component 20, the filter cotton belt 3 is in contact with the outside of the first reel 22, and the second reel 23 is used to cooperate with the first reel 22 to clamp the filter cotton belt 3 to ensure that the first reel 22 can pull the filter cotton belt 3 when driven by the driving component 20. In this embodiment, the driving component 20 includes a driving motor, the driving motor is fixedly connected to the filter cylinder 2, and the rotating shaft of the driving motor is arranged on the same straight line as the first reel 22, and the rotating shaft of the driving motor is fixedly connected to the first reel 22. The first reel 22 and the second reel 23 are rod-shaped, which can rotate relative to the filter cylinder 2, and the lengths of the first reel 22 and the second reel 23 are at least greater than the width of the filter cotton belt 3, so that the filter cotton belt 3 can move smoothly.

[0055] In this embodiment, by arranging the feeding mechanism on the same side as the discharge port 29, the length of the filter cotton belt 3 pulled by the first reel 22 can be better controlled. In actual use, the length of the filter cotton belt 3 required in the filtering mechanism 7 can be calculated and matched with the length of the filter cotton belt 3 that can be pulled by the first reel 22 rotating one circle. By setting the number of rotations of the first reel 22, the required pulling length can be determined, so that when the feeding mechanism feeds once, the filter cotton belt 3 in the filtering mechanism 7 can be just replaced.

[0056] Furthermore, as Figure 3As shown in the figure, the first reel 22 of the present application is provided with a sleeve 30, and the sleeve 30 is fixedly connected to the first reel 22, that is, the sleeve 30 is directly sleeved on the first reel 22. Among them, the sleeve 30 is provided with a plurality of annular protrusions, and the plurality of annular protrusions are arranged at equal intervals. The plurality of annular protrusions increase the contact points between the sleeve 30 and the filter cotton belt 3, thereby increasing the friction on the filter cotton belt 3, so that the first reel 22 and the second reel 23 can cooperate to pull the filter cotton belt 3.

[0057] Furthermore, as Figure 1 shown, the feeding mechanism further includes a third reel 24 and a fourth reel 25. The third reel 24 and the fourth reel 25 are located between the first reel 22 and the discharge port 29. The third reel 24 and the fourth reel 25 are used to tension the filter cotton belt 3 to prevent the filter cotton belt 3 from loosening between the discharge port 29 and the first reel 22, so as to avoid affecting the pulling effect of the first reel 22 on the filter cotton belt 3. The third reel 24 and the fourth reel 25 are arranged in parallel at intervals along the same vertical plane. Both ends of the third reel 24 are rotatably connected to the filter cylinder 2, and both ends of the second reel 23 are rotatably connected to the filter cylinder 2. Among them, in the vertical direction, the third reel 24 is located above the first reel 22; in the horizontal direction, the third reel 24 is located on the side of the first reel 22 close to the filter cylinder 2. The first reel 22 is located between the second reel 23 and the third reel 24, and there is a distance between the fourth reel 25 and the discharge port 29. The filter cotton belt 3 passes through the outside of the fourth reel 25, the inside of the third reel 24, and the outside of the first reel 22 in sequence, so that the routing of the filter cotton belt 3 between the discharge port 29 and the first reel 22 is not a single straight line, but a plurality of tortuous routings, which increases the force application points of the filter cotton belt 3. On the one hand, it can make the filter cotton belt 3 tensioned so that the acting force of the first reel 22 on the filter cotton belt 3 will not be dissipated, and on the other hand, it can make the filter cotton belt 3 move more smoothly to ensure smooth feeding.

[0058] As Figures 1 to 4As shown in the figure, a clamping mechanism 15 is provided on the filter cartridge 2. The clamping mechanism 15 is connected to the outer side wall of the filter cartridge 2 and is arranged outside the feed inlet 28 and the discharge outlet 29. The clamping mechanism 15 includes an upper clamping plate 16 and a lower clamping plate 17. There is a material passing channel 18 between the upper clamping plate 16 and the lower clamping plate 17. The material passing channel 18 is communicated with the feed inlet 28 and the discharge outlet 29 for the filter cotton belt 3 to pass through. Among them, the opening size of the material passing channel 18 in the vertical direction can be adjusted. When the filter mechanism 7 needs to replace the filter cotton belt 3, the material passing channel 18 becomes larger to accelerate the rapid entry of the filter cotton belt 3 into the filter mechanism 7 or the rapid output of the used filter cotton belt 3 from the filter mechanism 7. When the filter mechanism 7 is working, the opening of the material passing channel 18 in the vertical direction is reduced to be smaller than the thickness of the filter cotton belt 3 to clamp the filter cotton belt 3, so that the filter cotton belt 3 does not shake easily and shields the discharge outlet 29 and the feed inlet 28 to prevent the paint mist tail gas in the filter cartridge 2 from leaking out from the discharge outlet 29 and the feed inlet 28.

[0059] Specifically, as Figure 2 , Figure 3 shown, a driving oil cylinder 19 is provided at one end of the upper clamping plate 16 and the lower clamping plate 17 away from the material passing channel 18. The end of the driving oil cylinder 19 away from the material passing channel 18 is connected to the outer side wall of the filter cartridge 2. The driving oil cylinder 19 performs telescopic movement to drive the upper clamping plate 16 and the lower clamping plate 17 to move towards the material passing channel 18, that is, the upper clamping plate 16 and the lower clamping plate 17 perform relative displacement movement or opposite displacement movement to adjust the size of the material passing channel 18.

[0060] Furthermore, as Figure 5 shown, a roller 27 is provided on the side of the upper clamping plate 16 and the lower clamping plate 17 close to the material passing channel 18. The roller 27 can roll relative to the upper clamping plate 16 and the lower clamping plate 17. When the filter cotton belt 3 passes through the material passing channel 18, the filter cotton belt 3 contacts the roller 27, which can reduce the friction on the filter cotton belt 3, reduce the wear of the filter cotton belt 3, ensure the structural integrity of the filter cotton belt 3, and avoid affecting the filtering performance of the filter cotton belt 3.

[0061] It should be noted that the driving of the feeding mechanism, the clamping mechanism 15 and the reel 8 in this application is linked in the background. That is, when the feeding mechanism is driven, the clamping mechanism 15 and the reel 8 are also driven correspondingly to realize the function of automatically replacing the filter cotton belt 3. Moreover, the time for replacing the filter cotton belt 3, that is, the driving duration and the driving interval time of the feeding mechanism, can be set in the background, so that when the filter cotton belt 3 in the filter mechanism 7 is almost used up, the filter cotton belt 3 can be automatically and timely replaced, saving time and effort, saving labor costs and replacement procedures, and can also operate normally without supervision, greatly improving the filtering efficiency.

[0062] In another alternative embodiment of this application, as Figure 7As shown, the filtering mechanism 7 further includes support columns. The support columns are columnar structures, and the outer sidewalls of the support columns are connected to the sidewalls of the filter cylinder 2, and support columns are provided on both sides of the feed inlet 28 and the discharge outlet 29 of the filter cylinder 2. Among them, the support columns are divided into an upper support column 11 and a lower support column 12. The upper filter net 9 is connected to the upper support column 11, and the lower filter net 10 is connected to the lower support column 12.

[0063] Furthermore, the filter net includes a connecting portion 13 and a filtering portion 14. The connecting portion 13 is L-shaped. In the connecting portion 13 of the upper filter net 9, the connecting portion 13 is connected to the upper sidewall and the inner sidewall of the upper support column 11. In the connecting portion 13 of the lower filter net 10, the connecting portion 13 is connected to the lower sidewall and the inner sidewall of the lower support column 12. In this embodiment, the distance between the lower sidewall of the upper support column 11 and the upper sidewall of the lower support column 12 is L1, and the distance between the lower sidewall of the filtering portion 14 of the upper filter net 9 and the upper sidewall of the filtering portion 14 of the lower filter net 10 is L2. Among them, L1 > L2, that is, the distance between the two filtering portions 14 is smaller than the distance between the two support columns. The filter net is mostly made of metal materials, and its ends have burrs or sharp corners, which will damage the structure of the filter cotton belt 3. Therefore, such a setting can avoid the contact between the ends of the filter net and the filter cotton belt 3, reduce the wear of the filter net on the filter cotton belt 3, and ensure the structural integrity of the filter cotton belt 3 as much as possible, and ensure the filtering performance of the filter cotton belt 3.

[0064] In another alternative embodiment of the present application, as Figure 6 shown, a fifth reel 26 is provided between the feed inlet 28 and the reel 8. The fifth reel 26 is arranged parallel to the feed inlet 28. The filter cotton belt 3 passes through the fifth reel 26 after coming out of the reel 8 and then enters the filtering mechanism 7. The fifth reel 26 is connected to the reel 8 through a connecting frame. Among them, a detector 6 is provided between the feed inlet 28 and the reel 8. The detector 6 is connected to the connecting frame, and the filter cotton belt 3 passes through the detector 6. When the detector 6 detects the filter cotton belt 3, it indicates that there is still filter cotton belt 3 in the reel 8, that is, there is still filter cotton belt 3 in the processing device at this time. However, when the detector 6 does not detect the filter cotton belt 3, it indicates that the filter cotton belt 3 needs to be replaced. The detector 6 can be a sensing device such as an infrared sensor. The detector 6 is used to detect whether the filter cotton belt 3 needs to be replaced, which plays a role in timely reminding the operator to replace the filter cotton belt 3 and improves the use convenience.

[0066] The above has introduced the present application in detail. Specific examples are used herein to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the present application and its core idea. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present application, several improvements and modifications can still be made to the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
