Description

Technical Field

[0001] This utility model relates to the field of paint mist recovery technology in spraying lines, specifically to a high-efficiency paint mist recovery device for spraying lines. Background Technology

[0002] In modern industrial production, spraying technology is widely used in various fields, such as automobile manufacturing, furniture production, and machining. Spraying lines, as crucial production equipment for realizing the spraying process, play a key role in improving production efficiency and product quality. However, the spraying process generates a large amount of paint mist, which not only pollutes the production environment and affects workers' health but also wastes paint and increases production costs.

[0003] Many painting lines use simple filters or filter cotton to intercept paint mist. This method is simple in structure and low in cost, but the filtration effect is limited. The filters or filter cotton are easily clogged by paint mist and need to be replaced frequently, which leads to a decrease in production efficiency. Moreover, the filtration effect is not good for tiny paint mist particles, and a large amount of paint mist will still be emitted into the air, causing environmental pollution. Some paint mist treatment devices use centrifugal force to separate paint mist from air, but the separation effect for tiny paint mist particles is limited and the recovery efficiency is low.

[0004] Therefore, it is necessary to modify it by setting up a centrifugal recovery structure in combination with an adsorption recovery structure to improve the paint mist separation and treatment effect and recovery efficiency, reduce the production cost of the spraying line, and make it more convenient for users.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency paint mist recovery device for a spraying line, comprising a frame, a centrifuge cylinder fixedly connected to the left side of the top of the frame, an electrostatic adsorption box fixedly connected to the right side of the top of the frame, an air inlet pipe connected to the upper left side of the centrifuge cylinder, and a connecting pipe connecting the lower right side of the centrifuge cylinder to the left side of the electrostatic adsorption box. A drive motor is fixedly connected to the left side of the centrifuge cylinder via a bracket. The output end of the drive motor extends into the interior of the centrifuge cylinder and is fixedly connected to a shaft. The right end of the shaft is rotatably connected to the right side of the inner wall of the centrifuge cylinder via a sealed bearing seat. Several evenly distributed centrifugal fan blades are fixedly connected to the surface of the shaft. The inner wall of the cylinder has several paint flow grooves corresponding to the centrifugal fan blades. Adsorption structures are provided on both the front and rear sides of the upper part of the electrostatic adsorption box. A linear vibrator is fixedly connected to the right side of the electrostatic adsorption box, and a vibrating rod is fixedly connected to the output end of the linear vibrator. The left end of the vibrating rod extends into the interior of the electrostatic adsorption box and is fixedly connected to a vibrating plate. The left side of the vibrating plate is in contact with the right side of the adsorption structure. An axial flow fan is fixedly connected to the top of the electrostatic adsorption box, and the input end of the axial flow fan is connected to the top of the electrostatic adsorption box. Both the centrifugal cylinder and the electrostatic adsorption box have discharge ports at their bottoms. A three-way pipe is connected to the bottom of each discharge port, and a discharge valve pipe is connected to the bottom end of the three-way pipe.

[0007] In a preferred embodiment of this invention, the adsorption structure includes a round rod fixedly connected to the upper part of the electrostatic adsorption box. Moving rings are slidably connected to both sides of the surface of the round rod. A mounting frame is fixedly connected to the bottom of each moving ring. A detachable electrostatic adsorption plate is fixedly connected to the bottom of the mounting frame by bolts. Return springs are sleeved on both sides of the surface of the round rod. The outer ends of the return springs are fixedly connected to the inner wall of the electrostatic adsorption box. A high-voltage electrostatic generator is fixedly connected to the back of the electrostatic adsorption box.

[0008] As a preferred embodiment of this invention, the output end of the axial flow fan is threadedly connected to a purification hood, and the interior of the purification hood is equipped with a replaceable air purification filter.

[0009] As a preferred embodiment of this utility model, the surface of the reset spring is covered with a retractable rubber sleeve, the outer end of the rubber sleeve is fixedly connected to the inner wall of the electrostatic adsorption box, and the inner end of the rubber sleeve is fixedly connected to the outer side of the moving ring.

[0010] As a preferred embodiment of this utility model, both the centrifuge tube and the electrostatic adsorption box have cleaning and maintenance ports on their front sides, and the surfaces of both cleaning and maintenance ports are fixedly connected with sealing covers by bolts.

[0011] In a preferred embodiment of this invention, a sealed bearing is fixedly connected to the output end of the drive motor, the outer ring of the sealed bearing is fixedly connected to the inner wall of the centrifuge cylinder, a sealed sleeve is slidably connected to the surface of the vibrating rod, and the surface of the sealed sleeve is fixedly connected to the inner wall of the electrostatic adsorption box.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model achieves multi-stage treatment of paint mist by combining a centrifuge drum and an electrostatic adsorption box. Inside the centrifuge drum, a drive motor rotates the shaft and centrifugal fan blades at high speed, generating centrifugal force on the incoming air containing paint mist. Large paint mist particles are thrown towards the paint flow tank, initially separating the paint mist from the air and effectively removing most of the large paint mist particles, reducing the processing burden on the subsequent electrostatic adsorption box. The electrostatic adsorption box further refines the air after centrifugation, adsorbing small paint mist particles. The axial flow fan accelerates airflow within the device, improving processing efficiency. Simultaneously, the discharge ports, T-junctions, and discharge valves at the bottom of the centrifuge drum and electrostatic adsorption box facilitate the discharge and collection of the recovered paint mist, enabling subsequent processing and reuse. The entire device has a compact structure, with all components working collaboratively to efficiently recover paint mist generated by the painting line, reducing paint waste and improving the economic and environmental benefits of production.

[0013] 2. This utility model, by setting a sliding ring and mounting bracket on a round rod, makes the installation and disassembly of the electrostatic adsorption plate more convenient, facilitating regular cleaning and maintenance of the adsorption plate to ensure its adsorption performance. The reset spring allows the sliding ring to automatically reset after being subjected to external forces such as vibration, ensuring the stability of the adsorption structure. The high-voltage electrostatic generator provides high-voltage static electricity to the electrostatic adsorption plate, charging the paint mist particles and adsorbing them onto the adsorption plate, effectively improving the adsorption efficiency of small paint mist particles. When the electrostatic adsorption plate is saturated, it can be powered off, and then the linear vibrator can be started. The linear vibrator drives the vibrating plate to vibrate via a vibrating rod. Since the left side of the vibrating plate is in contact with the right side of the adsorption structure, the electrostatic adsorption plate vibrates. This vibration shakes off the paint mist adhering to the surface of the electrostatic adsorption plate, causing it to fall below the electrostatic adsorption box and then be discharged through the outlet. This design avoids the tedious operation of frequently replacing the adsorption plate in the traditional method, reducing maintenance costs and operational difficulty. At the same time, timely shaking off the paint mist also allows the electrostatic adsorption plate to quickly restore its adsorption capacity, extending the service life of the device and ensuring that the device can continuously and stably adsorb paint mist efficiently.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 4 As shown, this utility model provides a high-efficiency paint mist recovery device for a spraying line, including a frame 1. A centrifuge cylinder 2 is fixedly connected to the left side of the top of the frame 1, and an electrostatic adsorption box 3 is fixedly connected to the right side of the top of the frame 1. An air inlet pipe 4 is connected to the upper left side of the centrifuge cylinder 2, and the lower right side of the centrifuge cylinder 2 is connected to the left side of the electrostatic adsorption box 3 through a connecting pipe. A drive motor 5 is fixedly connected to the left side of the centrifuge cylinder 2 through a bracket. The output end of the drive motor 5 passes through the interior of the centrifuge cylinder 2 and is fixedly connected to a shaft 6. The right end of the shaft 6 is rotatably connected to the right side of the inner wall of the centrifuge cylinder 2 through a sealed bearing seat. Several evenly distributed centrifugal fan blades 7 are fixedly connected to the surface of the shaft 6. Several flow channels corresponding one-to-one with the centrifugal fan blades 7 are opened on the inner wall of the centrifuge cylinder 2. The inner walls of the paint tank 8, centrifuge cylinder 2, and paint flow tank 8 are all coated with an anti-stick coating. Adsorption structures 9 are provided on both the front and rear sides of the upper part of the electrostatic adsorption box 3. A linear vibrator 10 is fixedly connected to the right side of the electrostatic adsorption box 3. A vibrating rod 11 is fixedly connected to the output end of the linear vibrator 10. The left end of the vibrating rod 11 penetrates into the interior of the electrostatic adsorption box 3 and is fixedly connected to a vibrating plate 12. The left side of the vibrating plate 12 is attached to the right side of the adsorption structure 9. An axial flow fan 13 is fixedly connected to the top of the electrostatic adsorption box 3. The input end of the axial flow fan 13 is connected to the top of the electrostatic adsorption box 3. Both the centrifuge cylinder 2 and the electrostatic adsorption box 3 have discharge ports at the bottom. A three-way pipe 14 is connected to the bottom of the discharge port. A discharge valve pipe is connected to the bottom end of the three-way pipe 14.

[0018] refer to Figure 3 and Figure 4 The adsorption structure 9 includes a round rod 15 fixedly connected to the upper part of the electrostatic adsorption box 3. Moving rings 16 are slidably connected to both sides of the surface of the round rod 15. A mounting bracket 17 is fixedly connected to the bottom of the moving ring 16. A detachable electrostatic adsorption plate 18 is fixedly connected to the bottom of the mounting bracket 17 by bolts. A return spring 19 is sleeved on both sides of the surface of the round rod 15. The outer end of the return spring 19 is fixedly connected to the inner wall of the electrostatic adsorption box 3. A high-voltage electrostatic generator 20 is fixedly connected to the back of the electrostatic adsorption box 3. The high-voltage electrostatic generator 20 is electrically connected to the electrostatic adsorption plate 18 through a wire.

[0019] As a technical optimization of this utility model, by setting a sliding ring 16 and a mounting bracket 17 slidably connected on the round rod 15, the installation and disassembly of the electrostatic adsorption plate 18 are made more convenient, facilitating regular cleaning and maintenance of the adsorption plate to ensure its adsorption performance. The setting of the reset spring 19 enables the sliding ring 16 to automatically reset after being subjected to external forces such as vibration, ensuring the stability of the adsorption structure 9. The high-voltage electrostatic generator 20 provides high-voltage electrostatics to the electrostatic adsorption plate 18, causing the paint mist particles to be charged and adsorbed on the adsorption plate, effectively improving the adsorption efficiency of small paint mist particles. When the electrostatic adsorption plate 18 is saturated, it can be operated on a timed basis (e.g., once every 2-3 hours) according to the type of paint mist, and then the power can be cut off, and the linear vibrator 10 can be started. The linear vibrator 10 drives the vibrating plate 12 to vibrate via the vibrating rod 11. Since the left side of the vibrating plate 12 is in contact with the right side of the adsorption structure 9, the electrostatic adsorption plate 18 vibrates. This vibration can shake off the paint mist attached to the surface of the electrostatic adsorption plate 18, causing it to fall below the electrostatic adsorption box 3 and then be discharged through the outlet. This design avoids the tedious operation of frequently replacing the adsorption plate in the traditional method, reducing maintenance costs and operating difficulty. At the same time, timely shaking off the paint mist can also allow the electrostatic adsorption plate 18 to quickly restore its adsorption capacity, extending the service life of the device and ensuring that the device can continuously and stably adsorb paint mist efficiently.

[0020] refer to Figure 2 The output end of the axial flow fan 13 is threadedly connected to a purification hood 21, and a replaceable air purification filter is installed inside the purification hood 21.

[0021] As a technical optimization of this utility model, the environmental performance of the device is further improved by setting up a purification hood 21 and an internal replaceable air purification filter. Although most of the paint mist has been removed from the air after treatment by the centrifuge 2 and the electrostatic adsorption box 3, it may still contain some minor impurities and odors. The air purification filter can filter and purify these remaining impurities and odors, making the exhaust air cleaner and meeting environmental emission standards. The replaceable design allows for timely replacement when the filter becomes saturated or reaches its service life, ensuring the continuity of the purification effect. The threaded connection makes the installation and disassembly of the purification hood 21 simple and convenient, facilitating the maintenance and replacement of the purification hood 21 and the filter, improving the ease of use and overall performance of the device.

[0022] refer to Figure 3 The surface of the return spring 19 is covered with a retractable rubber sleeve 22. The outer end of the rubber sleeve 22 is fixedly connected to the inner wall of the electrostatic adsorption box 3, and the inner end of the rubber sleeve 22 is fixedly connected to the outer side of the moving ring 16.

[0023] As a technical optimization of this utility model, the retractable rubber sleeve 22 fitted onto the surface of the return spring 19 plays an important role. The rubber sleeve 22 prevents impurities such as paint mist from adhering to the return spring 19, avoiding any impact on its elasticity and return performance due to paint mist contamination. The retractable design ensures that the rubber sleeve 22 does not affect the normal extension and retraction of the return spring 19 or the sliding of the moving ring 16, extending the service life of the return spring 19, reducing malfunctions of the adsorption structure 9 caused by damage to the return spring 19, and ensuring the stability and reliability of the adsorption structure 9, thereby ensuring the stable and efficient operation of the entire device.

[0024] refer to Figure 1 Both the centrifuge tube 2 and the electrostatic adsorption box 3 have cleaning and maintenance ports on their front sides, and the surfaces of both cleaning and maintenance ports are fixedly connected with sealing covers 23 by bolts.

[0025] As a technical optimization of this utility model, the inclusion of a cleaning and maintenance port and a sealing cover 23 facilitates the maintenance and repair of the device. During long-term operation, a certain amount of paint mist and impurities accumulate on the inner wall of the centrifuge cylinder 2 and inside the electrostatic adsorption box 3, affecting the device's performance and recovery efficiency. The cleaning and maintenance port allows operators to easily enter the device for cleaning and maintenance. The sealing cover 23 is bolted to ensure the device's airtightness and prevent paint mist leakage. When cleaning or maintenance is required, simply remove the bolts and open the sealing cover 23; the operation is simple and quick. This helps to promptly identify and resolve problems inside the device, ensuring its normal operation, extending its service life, and improving its reliability and stability.

[0026] refer to Figure 3 A sealed bearing 24 is fixedly connected to the output end of the drive motor 5. The outer ring of the sealed bearing 24 is fixedly connected to the inner wall of the centrifuge cylinder 2. A sealed sliding sleeve 25 is slidably connected to the surface of the vibrating rod 11. The surface of the sealed sliding sleeve 25 is fixedly connected to the inner wall of the electrostatic adsorption box 3.

[0027] As a technical optimization of this utility model, the sealing performance and stability of the device are effectively improved by using the sealed bearing 24 at the output end of the drive motor 5 and the sealed sliding sleeve 25 on the surface of the vibrating rod 11. The outer ring of the sealed bearing 24 is fixedly connected to the inner wall of the centrifuge cylinder 2, which can prevent the paint mist and air in the centrifuge cylinder 2 from leaking from the gap at the output end of the drive motor 5, ensuring the pressure stability and paint mist separation effect in the centrifuge cylinder 2. The surface of the sealed sliding sleeve 25 is fixedly connected to the inner wall of the electrostatic adsorption box 3, which can prevent the air and paint mist in the electrostatic adsorption box 3 from leaking from the connection between the vibrating rod 11 and the box body, ensuring the normal working environment of the electrostatic adsorption box 3. At the same time, the setting of the sealed bearing 24 and the sealed sliding sleeve 25 can also reduce the entry of external dust and impurities into the device, reduce the wear and failure rate of the device, improve the service life and operational stability of the device, and ensure the performance and reliability of the entire paint mist high-efficiency recovery device for the spraying line.

[0028] The working principle and usage process of this utility model are as follows: In use, firstly, connect the exhaust port of the paint spraying line to the air inlet connecting pipe 4. Air containing paint mist enters the centrifuge cylinder 2 through the air inlet connecting pipe 4. A removable primary filter (not shown) is installed inside the connecting pipe 4. The drive motor 5 drives the shaft 6 and the centrifugal fan blades 7 on its surface to rotate at high speed, causing the air to form a high-speed rotating airflow inside the centrifuge cylinder 2. The air containing paint mist moves spirally downwards along the inner wall of the centrifuge cylinder 2 under the push of the centrifugal blades 7. Large particles of paint mist are thrown towards the paint flow trough 8 and slide to the bottom of the centrifuge cylinder 2. Unseparated medium and small particles of paint mist are guided to the connecting channel by the airflow. After the medium particles of paint mist are intercepted by the primary filter, the remaining small particles of paint mist enter the electrostatic adsorption box 3. The high-voltage electrostatic generator 20 inside the centrifuge 3 applies high-voltage static electricity to the electrostatic adsorption plate 18 through wires, causing small paint mist particles to become charged and adsorbed onto the surface of the electrostatic adsorption plate 18. At the same time, the axial flow fan 13 is started to accelerate the airflow in the device and improve the processing efficiency. When the electrostatic adsorption plate 18 is saturated, the power is cut off, the axial flow fan 13 is turned off, and the linear vibrator 10 is started. The linear vibrator 10 drives the vibrating plate 12 to vibrate through the vibrating rod 11. The vibrating plate 12 causes the electrostatic adsorption plate 18 of the adsorption structure 9 to vibrate, shaking off the paint mist adhering to the surface and falling to the bottom of the electrostatic adsorption box 3. The bottom of the inner wall of the electrostatic adsorption box 3 is provided with a slope, and the vibrated paint mist particles will slide naturally along the slope to the bottom discharge port, avoiding the accumulation of particles in the box. The paint mist separated and shaken off in the centrifuge 2 and the electrostatic adsorption box 3 is discharged and collected through the bottom discharge port, the three-way pipe 14 and the discharge valve pipe. The entire device works together efficiently to achieve efficient recovery of paint mist from the spraying line.
