Description

Technical Field

[0001] The present invention discloses a filtering and paint mist treatment device for an automobile painting booth, belonging to the technical field of painting waste gas treatment. Background Art

[0002] When an automobile is produced, its surface needs to be painted. A painting booth is a device that provides a special environment for painting operations. Since a large amount of paint mist and waste gas are generated during painting work, direct discharge is likely to cause pollution to the external environment. Therefore, a waste gas adsorption treatment device is required to treat the paint mist and waste gas generated during painting. Most of the existing treatment devices rely on activated carbon and catalysts to adsorb the paint mist and waste gas. However, since activated carbon has a certain service life, it needs to be replaced in a timely manner after it fails. The existing method relies on manual replacement, resulting in time-consuming and laborious disassembly and assembly of the treatment device, low efficiency, and even affecting the progress of painting work. Summary of the Invention

[0003] The purpose of the present invention is to solve the problems in the prior art and provide a filtering and paint mist treatment device for an automobile painting booth.

[0004] The present invention achieves the above purpose through the following technical solutions. A filtering and paint mist treatment device for an automobile painting booth includes a frame, an adsorbent, a mounting column, and a power member. A fixed cylinder is provided on the frame. The mounting column is rotatably arranged in the fixed cylinder, and an air inlet pipe and an exhaust pipe are respectively arranged at both ends of the mounting column. Both the air inlet pipe and the exhaust pipe are rotatably arranged with the fixed cylinder, and one end of the air inlet pipe extends into the painting booth. An induced draft fan is connected to the air inlet pipe or the exhaust pipe. The fixed cylinder has two through grooves for the adsorbent to pass through, and a material guiding frame is arranged at the fixed cylinder corresponding to one of the through grooves. The included angle formed by the two through grooves and the axis of the fixed cylinder is 120°. Three U-shaped grooves with an included angle of 120° with each other are arranged on the mounting column. The adsorbent includes a gas guiding cylinder and an adsorption cylinder. One end of the adsorption cylinder is fixedly connected to the gas guiding cylinder, and the adsorption cylinder divides the inner cavity of the gas guiding cylinder into an air inlet cavity and an air outlet cavity. The adsorption cylinder is a net cylinder structure, and activated carbon is filled inside it. Guide air holes communicating with the air inlet cavity and the air outlet cavity are arranged at both ends of the gas guiding cylinder. Movable clamping members for clamping the adsorbent are arranged at both ends of the mounting column corresponding to the U-shaped grooves. A diversion hole is arranged on the movable clamping member, and a hose is connected between the diversion hole and the air inlet pipe and the exhaust pipe. The power member is installed on the frame and the exhaust pipe and is used to drive the mounting column to intermittently rotate by 120°. A driving member for driving the movable clamping members at both ends of the same U-shaped groove to approach each other is arranged on the fixed cylinder.

[0005] Preferably, the movable clamping member includes a sliding rod, a first spring, a sealing sleeve, a second spring and a plug. The two ends of the mounting column are provided with mounting plates. The diversion hole is in an L-shaped structure and is located inside the sealing sleeve. One end of the sliding rod passes through the mounting plate and extends into the diversion hole. The plug is located in the diversion hole and is fixedly connected to the sliding rod by a bolt. The first spring is sleeved outside the sliding rod and applies a force to block the diversion hole to the plug. The two ends of the second spring are respectively in contact with the sealing sleeve and the sliding rod, and the second spring applies a force to press the sealing sleeve against the mounting plate.

[0006] Preferably, both ends of the air guide cylinder are provided with frustum cones, and a sinking groove matched with the frustum cone is arranged on one side of the sealing sleeve.

[0007] Preferably, the driving member includes an arc-shaped block. The arc-shaped block is installed inside the fixed cylinder by a bolt, and the arc-shaped block is located on the circumference formed by the rotation of the sliding rod. The central angle of the arc-shaped block is less than 90°, and the height difference between both ends of the arc-shaped block is greater than the maximum sliding distance of the sealing sleeve.

[0008] Preferably, a support column is arranged between the mounting plate and the mounting column, and the mounting plate is fixedly connected to the mounting column by a bolt. The height of the sealing sleeve is greater than the height of the support column.

[0009] Preferably, the power member includes a motor, a driving pulley, a driven pulley and a belt. The motor is fixed on the frame. The driving pulley is fixed on the output shaft of the motor.

Detailed implementation manners

[0021] 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 the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] As Figures 1 - 8As shown in the figure, an automotive spray booth filter mist treatment device includes a frame 3, an adsorbent 5, a mounting post 8, and a power component 14. A fixed cylinder 1 is provided on the frame 3. The mounting post 8 is rotatably arranged within the fixed cylinder 1. Both ends of the mounting post 8 are respectively provided with an intake pipe 2 and an exhaust pipe 15. The intake pipe 2 and the exhaust pipe 15 are both rotatably arranged with the fixed cylinder 1. One end of the intake pipe 2 extends into the spray booth. A blower is connected to the intake pipe 2 or the exhaust pipe 15. The fixed cylinder 1 has two through slots 6 for the adsorbent 5 to pass through. A material guiding frame 4 is provided on the fixed cylinder 1 corresponding to one of the through slots 6. The included angle formed by the two through slots 6 and the axis of the fixed cylinder 1 is 120°. Three U-shaped grooves 7 with an included angle of 120° with each other are provided on the mounting post 8. The adsorbent 5 includes a gas guiding cylinder 32 and an adsorption cylinder 30. One end of the adsorption cylinder 30 is fixedly connected to the gas guiding cylinder 32. The adsorption cylinder 30 divides the inner cavity of the gas guiding cylinder 32 into an intake cavity 27 and an outlet cavity 31. The adsorption cylinder 30 is a mesh cylinder structure and is filled with activated carbon inside. Gas guiding holes 28 communicating with the intake cavity 27 and the outlet cavity 31 are provided at both ends of the gas guiding cylinder 32. Movable clamping members 16 for clamping the adsorbent 5 are provided at both ends of the mounting post 8 corresponding to the U-shaped grooves 7. The movable clamping members 16 have diversion holes 22. Hoses 23 are connected between the diversion holes 22 and the intake pipe 2 and the exhaust pipe 15. The power component 14 is installed on the frame 3 and the exhaust pipe 15 and is used to drive the mounting post 8 to rotate intermittently by 120°. A driving member for driving the movable clamping members 16 at both ends of the same U-shaped groove 7 to approach each other is provided on the fixed cylinder 1.

[0023] The movable clamping member 16 includes a sliding rod 17, a first spring 18, a sealing sleeve 19, a second spring 24 and a plug 21. Installation discs 12 are provided at both ends of the installation column 8. The diversion hole 22 is of an L-shaped structure and is located within the sealing sleeve 19. One end of the sliding rod 17 passes through the installation disc 12 and extends into the diversion hole 22. The plug 21 is located within the diversion hole 22 and is fixedly connected to the sliding rod 17 by a bolt. The first spring 18 is sleeved outside the sliding rod 17 and applies a force to block the diversion hole 22 to the plug 21. Both ends of the second spring 24 abut against the sealing sleeve 19 and the sliding rod 17 respectively, and the second spring 24 applies a force to abut against the installation disc 12 to the sealing sleeve 19. The driving member includes an arc-shaped block 25. The arc-shaped block 25 is installed inside the fixed cylinder 1 by a bolt, and the arc-shaped block 25 is located on the circumference formed by the rotation of the sliding rod 17. The central angle of the arc-shaped block 25 is less than 90°, and the height difference between both ends of the arc-shaped block 25 is greater than the maximum sliding distance of the sealing sleeve 19. When one end of the sliding rod 17 abuts against the arc-shaped block 25, the sliding rod 17 starts to compress the first spring 18 and drives the sealing sleeve 19 to slide within the U-shaped groove 7, causing the sealing sleeve 19 to approach the suction member 5. When the two sealing sleeves 19 clamp the suction member 5, the sealing sleeve 19 cannot move. At this time, the sliding rod 17 continues to be pushed by the arc-shaped block 25 and starts to compress the second spring 24. In this way, the sliding rod 17 can drive the plug 21 to move, causing the diversion hole 22 to open, so that the air can smoothly flow through the air inlet pipe 2, the suction member 5 and the exhaust pipe 15.

[0024] Conical platforms 29 are provided at both ends of the air guide cylinder 32. A sunk groove 20 that cooperates with the conical platform 29 is provided on one side of the sealing sleeve 19. When the sliding rod 17 drives the sealing sleeve 19 to approach the air guide cylinder 32, relying on the cooperation between the conical platform 29 and the sunk groove 20, the sealing sleeve 19 can be sealed with the conical platform 29, enabling the paint mist and waste gas to smoothly enter the suction member 5 from the diversion hole 22 or flow from the suction member 5 to the diversion hole 22.

[0025] Support columns 26 are provided between the installation disc 12 and the installation column 8, and the installation disc 12 is fixedly connected to the installation column 8 by a bolt. The height of the sealing sleeve 19 is greater than the height of the support columns 26. After the installation disc 12 and the installation column 8 are assembled inside the fixed cylinder 1, one end of the sealing sleeve 19 abuts against the installation disc 12, and the other end is located within the U-shaped groove 7, enabling one end of the sliding rod 17 to smoothly drive the sealing sleeve 19 to slide within the U-shaped groove 7 when pressed by the arc-shaped block 25.

[0026] 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 outside 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 post 8, the mounting post 8 can drive the suction accessory 5 to rotate synchronously, so that the suction accessory 5 rotates to different positions, thereby achieving the effect of purifying paint mist and waste gas. By setting the cycle and working time of the intermittent operation of the motor 13, the suction accessory 5 can be automatically replaced after being used for a period of time.

[0027] Working principle: Place the unused suction accessory 5 into the material guiding frame 4, and one of the suction accessories 5 enters the U-shaped groove 7 of the mounting post 8. Then, the motor 13 drives the mounting post 8 to rotate 120°. The mounting post 8 drives the movable clamping member 16 and the suction accessory 5 to rotate synchronously by 120°. During this rotation, the movable clamping member 16 will be abutted against the arc-shaped block 25 by the sliding rod 17 and slide along the surface of the arc-shaped block 25. The sliding rod 17 is pushed and starts to compress the first spring 18, and drives the sealing sleeve 19 to abut against the suction accessory 5 until the two sealing sleeves 19 clamp the air guide cylinder 32. Sealing is achieved by the cooperation of the conical platform 29 and the sunk groove 20. The sliding rod 17 continues to be pushed by the arc-shaped block 25 and starts to compress the second spring 24, so that the plug 21 moves and no longer blocks the diversion hole 22. In this way, the induced draft fan generates a negative pressure on the paint mist and waste gas, so that they are sucked into the intake pipe 2, and after being adsorbed by the activated carbon in the suction accessory 5, they are discharged from the exhaust pipe 15. When the suction accessory 5 has been used for a period of time, the motor 13 continues to drive the mounting post 8 to rotate 120°. During this rotation, the sliding rod 17 is no longer pressed by the arc-shaped block 25. The sliding rod 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 suction accessory 5. When the suction accessory 5 rotates to align with the through groove 6 at the lowest position, the suction accessory 5 can fall from the through groove 6. According to the above principle, the automatic regular replacement of the suction accessory 5 can be realized 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 suction accessories 5 is treating the paint mist and waste gas, the diversion holes 22 in the movable clamping members 16 at the other two positions are blocked by the plugs 21, so that the paint mist will not leak.
