Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0013] like Figure 1-Figure 8As shown, a paint mist filtering treatment device for an automobile spray paint room comprises a frame 3, an adsorbent 5, a mounting column 8 and a power member 14, a fixed cylinder 1 is arranged on the frame 3, the mounting column 8 is rotatably arranged in the fixed cylinder 1, and an air intake pipe 2 and an exhaust pipe 15 are respectively arranged at both ends of the mounting column 8, the air intake pipe 2 and the exhaust pipe 15 are both rotatably arranged with the fixed cylinder 1, and one end of the air intake pipe 2 extends into the spray paint room, an induced draft fan is connected to the air intake pipe 2 or the exhaust pipe 15, the fixed cylinder 1 has two through slots 6 for the adsorbent 5 to pass through, and a guide rack 4 is arranged at a position of the fixed cylinder 1 corresponding to one of the through slots 6, the angle formed by the two through slots 6 and the axis of the fixed cylinder 1 is 120°, three U-shaped slots 7 with an angle of 120° to each other are arranged on the mounting column 8, the adsorbent 5 comprises an air guide cylinder 32 and an adsorbent cylinder 3 0, one end of the adsorption cylinder 30 is fixedly connected to the air guide cylinder 32, and the adsorption cylinder 30 divides the inner cavity of the air guide cylinder 32 into an air inlet cavity 27 and an air outlet cavity 31. The adsorption cylinder 30 is a mesh cylinder structure, and its inner side is filled with activated carbon. Both ends of the air guide cylinder 32 are provided with air guide holes 28 connected with the air inlet cavity 27 and the air outlet cavity 31. Both ends of the mounting column 8 corresponding to the U-shaped groove 7 are provided with movable clamping parts 16 for clamping the adsorption part 5, and the movable clamping parts 16 have guide holes 22, and a hose 23 is connected between the guide holes 22 and the air inlet pipe 2 and the exhaust pipe 15. The power part 14 is installed on the frame 3 and the exhaust pipe 15, and is used to drive the mounting column 8 to rotate intermittently 120°, and a driving part for driving the movable clamping parts 16 at both ends of the same U-shaped groove 7 to approach each other is provided on the fixed cylinder 1.

[0014] The movable clamping member 16 includes a slide bar 17, a first spring 18, a sealing sleeve 19, a second spring 24 and a plug 21. The mounting plates 12 are provided at both ends of the mounting column 8. The guide hole 22 is L-shaped and is located in the sealing sleeve 19. One end of the slide bar 17 passes through the mounting plate 12 and extends into the guide hole 22. The plug 21 is located in the guide hole 22 and is fixedly connected to the slide bar 17 by bolts. The first spring 18 is sleeved on the outer side of the slide bar 17 and applies a force to the plug 21 to block the guide hole 22. The two ends of the second spring 24 are respectively in contact with the sealing sleeve 19 and the slide bar 17, and the second spring 24 applies a force to the sealing sleeve 19 to contact the mounting plate 12. The driving member includes an arc block 25, which is mounted on the fixed cylinder by bolts. 1, and the arc block 25 is located on the circumference formed by the rotation of the slide bar 17, the central angle of the arc block 25 is less than 90°, and the height difference between the two ends of the arc block 25 is greater than the maximum sliding distance of the sealing sleeve 19. When one end of the slide bar 17 contacts the arc block 25, the slide bar 17 begins to compress the first spring 18 and drives the sealing sleeve 19 to slide in the U-shaped groove 7, so that the sealing sleeve 19 is close to the adsorption member 5. When the two sealing sleeves 19 clamp the adsorption member 5, the sealing sleeve 19 cannot move. At this time, the slide bar 17 continues to be pushed by the arc block 25 and begins to compress the second spring 24, so that the slide bar 17 can drive the plug 21 to move, so that the guide hole 22 is opened, so that the air intake pipe 2, the adsorption member 5 and the exhaust pipe 15 can smoothly realize air circulation.

[0015] Both ends of the air guide cylinder 32 are provided with a frustum 29, and one side of the sealing sleeve 19 is provided with a groove 20 that cooperates with the frustum 29. When the sliding rod 17 drives the sealing sleeve 19 to approach the air guide cylinder 32, the sealing sleeve 19 and the frustum 29 can be sealed by relying on the cooperation between the frustum 29 and the groove 20, so that the paint mist and exhaust gas can smoothly enter the adsorption component 5 from the guide hole 22 or flow from the adsorption component 5 to the guide hole 22.

[0016] A support column 26 is provided between the mounting plate 12 and the mounting column 8, and the mounting plate 12 is fixedly connected to the mounting column 8 by bolts. The height of the sealing sleeve 19 is greater than the height of the support column 26. After the mounting plate 12 and the mounting column 8 are assembled in the fixed cylinder 1, one end of the sealing sleeve 19 contacts the mounting plate 12, and the other end is located in the U-shaped groove 7, so that when one end of the sliding rod 17 is pressed by the arc block 25, it can smoothly drive the sealing sleeve 19 to slide in the U-shaped groove 7.

[0017] The power component 14 includes a motor 13, a driving pulley 11, a driven pulley 9 and a belt 10. The motor 13 is fixed on the frame 3, the driving pulley 11 is fixed on the output shaft of the motor 13, the driven pulley 9 is fixed on the exhaust pipe 15, and the belt 10 is sleeved on the outer sides of the driving pulley 11 and the driven pulley 9. The motor 13 drives the driving pulley 11 to rotate, so that the belt 10 drives the driven pulley 9 and the exhaust pipe 15 to rotate. Since one end of the exhaust pipe 15 is fixedly connected to the mounting column 8, the mounting column 8 can drive the adsorbent 5 to rotate synchronously, so that the adsorbent 5 rotates to different positions, thereby achieving the effect of purifying paint mist and exhaust gas. By setting the intermittent working cycle and working time of the motor 13, the adsorbent 5 can be automatically replaced after being used for a period of time.

[0018] Working principle: put the unused adsorption parts 5 into the guide rack 4, one of the adsorption parts 5 enters the U-shaped groove 7 of the mounting column 8, and then the motor 13 drives the mounting column 8 to rotate 120°, so that the mounting column 8 drives the movable clamping part 16 and the adsorption part 5 to rotate 120° synchronously. During the rotation process, the movable clamping part 16 will be abutted against the arc block 25 by the sliding rod 17, and slide along the surface of the arc block 25, so that the sliding rod 17 is pushed and begins to compress the first spring 18, and drives the sealing sleeve 19 to abut against the adsorption part 5, until the two sealing sleeves 19 clamp the air guide tube 32, and the sealing is achieved by the cooperation of the cone 29 and the sink 20, and the sliding rod 17 continues to be pushed by the arc block 25 to start compressing the second spring 24, so that the plug 21 moves and no longer blocks the guide hole 22, so that the induced draft fan generates negative pressure on the paint mist and exhaust gas, thereby sucking them into the intake pipe 2 and passing through the adsorption part 5 is discharged from the exhaust pipe 15 after adsorption treatment of the activated carbon. After the adsorption member 5 has been used for a period of time, the motor 13 continues to drive the mounting column 8 to rotate 120°. During the rotation process, the slide bar 17 is no longer subjected to the pressing thrust of the arc block 25. The slide bar 17 and the sealing sleeve 19 are reset under the drive of the first spring 18 and the second spring 24, so that the two movable clamping members 16 release the clamping of the adsorption member 5. When the adsorption member 5 is rotated to align with the through groove 6 at the lowest point, the adsorption member 5 can fall from the through groove 6. According to the above principle, the adsorption member 5 can be automatically and regularly replaced without manual operation, and the replacement time is very short, so that the painting work of the car can continue. In this embodiment, when one of the adsorption members 5 is processing paint mist and exhaust gas, the guide holes 22 in the movable clamping members 16 at the other two positions are closed by the plug 21, so that the paint mist will not leak out.
