Description

Technical Field

[0001] This invention relates to the field of paint mist recovery structure technology, specifically a paint mist filtration and recovery system. Background Technology

[0002] In traditional paint mist treatment technology, paint mist collection and recycling mainly rely on simple filtration devices, with a single filtration method (simple filter screen), which has some obvious shortcomings.

[0003] On the one hand, paint mist has a high viscosity and easily adheres to filter materials, making it difficult to handle. This leads to a decrease in filtration efficiency and the need for frequent replacement of filter materials. On the other hand, paint mist contains a large number of harmful substances, and direct discharge will seriously pollute the environment. Existing recycling technologies often can only recover a portion of the paint mist, and the recovery effect is unstable, resulting in a low paint mist recovery rate and increased treatment costs.

[0004] Therefore, we propose a paint mist filtration and recovery system. Summary of the Invention

[0005] The purpose of this invention is to provide a paint mist filtration and recovery system to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides a paint mist filtration and recovery system, including a paint mist purification device. The paint mist purification device delivers the paint mist to a separation device through a spray pipe. A return water pipe is connected to the bottom of the separation device, and the other end of the return water pipe is connected to the paint mist purification device. After multiple cycles of filtration and purification, the paint mist purification device recovers the paint into a recovery bucket through a recovery pump.

[0007] The separation device includes a device body, one end of which is provided with a perforated mesh and the other end with a wire mesh. The top of the device body is provided with a water spraying device for diluting the viscosity of the paint mist. An oil slinger is rotatably connected inside the device body, and a collection pipe is connected to the bottom of the device body.

[0008] Paint mist first passes through a perforated mesh, then is treated by a water spraying device before entering an oil slinger. Most of it is collected and enters a collection pipe, while a small portion enters a metal wire mesh.

[0009] It also includes: a fixed plate that is fixedly connected to the main body of the equipment, a rotating wheel that is fixedly connected to the central shaft of the oil slinger on the fixed plate, a belt that drives the two rotating wheels on two adjacent fixed plates, an explosion-proof motor that is fixedly connected to the main body of the equipment, the output shaft of the explosion-proof motor that is fixedly connected to one of the rotating wheels, and a tensioning wheel that is rotatably connected to the fixed plate and engages with the belt.

[0010] A rotating shaft is fixedly connected to the edge of the rotating wheel, and a horizontal plate is rotatably connected between two adjacent rotating shafts. A connecting rope is rotatably connected to the rotating shaft, and the connecting rope is in sliding cooperation with the tensioning wheel. A fine division plate located above the collection tube is rotatably connected to the bottom of the connecting rope, and a sliding plate is rotatably connected to the fine division plate.

[0011] Furthermore, a sleeve is fixedly connected inside the collecting tube, and the sleeve is slidably connected to the slide plate through a tension spring. The subdivision plate is rotatably connected to the slide plate, so that the reciprocating subdivision plate moves up and down simultaneously.

[0012] Furthermore, the position of the rotating connection between the slide plate and the subdivision plate is close to one end of the subdivision plate, ensuring that the arc distance of the reciprocating movement of one end of the subdivision plate is large.

[0013] Furthermore, a vertical rope is fixedly connected between the top of the skateboard and the connecting rope, which, together with a tension spring and a sleeve, drives the skateboard to move up and down, causing the sub-boards to move up and down and sway simultaneously.

[0014] Furthermore, a support plate that fits against the vertical rope is fixedly connected to the fixing plate to ensure the stable movement of the vertical rope.

[0015] Furthermore, an arc-shaped plate is fixedly connected to one end of one of the shafts to enhance the recycling effect.

[0016] Furthermore, the horizontal plate is provided with a sliding groove for the connecting rope to move, and a pressure ball is fixedly connected to the end of the sliding groove, so that the horizontal plate moves to support the connecting rope and facilitates shaking.

[0017] Furthermore, both the maintaining plate and the vertical rope pass through the sliding groove, and a pressure block located between the inclined connecting rope and the vertical rope is slidably fitted in the sliding groove to limit the distance between the connecting rope and the vertical rope.

[0018] Furthermore, an adjusting plate is slidably fitted onto the fixed plate, and the adjusting plate is pressed and fixed against the fixed plate by a threaded rod. The tension wheel is rotatably connected to the adjusting plate, and the maintaining plate is fixedly connected to the adjusting plate, thereby adjusting the pressing action of the tension wheel on the belt.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] In this application, the paint mist enters the equipment body through the perforated mesh. Water is sprayed onto the paint mist passing through the perforated mesh through the spray pipe of the water spraying device to dilute the paint mist and prevent the paint mist from being too viscous and adhering to the inside of the equipment body, resulting in failure to collect or low collection efficiency.

[0021] Furthermore, most of the paint mist is collected through the oil-slinging plate, while a small portion of the remaining paint mist is recovered through the metal wire mesh, ensuring comprehensive recovery and ultimately achieving efficient and stable paint mist recovery.

[0022] The rotating wheel causes one end of the connecting rope to rotate through the rotating shaft, while the other end pulls the subdivision plate to rotate and connect, causing the subdivision plate to reciprocate on the skateboard to refine the paint and prevent it from sticking. The vertical rope that moves up and down actively pulls the skateboard, and together with the tension spring, it further increases the swaying amplitude of the subdivision plate.

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] Please see Figures 1-13 This invention provides a paint mist filtration and recovery system, comprising a device body 1, one end of which is provided with a perforated mesh 2 (which initially filters larger paint mist particles), and the other end is provided with a metal wire mesh 3 (which acts as a secondary filter to capture smaller paint mist particles). The top of the device body 1 is provided with a water spraying device 4 for diluting the viscosity of the paint mist. An oil slinger 5 is rotatably connected inside the device body 1 (the oil slinger 5 collects more paint mist through rotation, reducing paint mist escape and facilitating further separation and recovery of the paint mist). The bottom of the device body 1 is connected to a collection pipe 6.

[0040] Paint mist first passes through perforated mesh 2, then is treated by water spraying device 4 before entering oil slinger 5. Most of it is collected and enters collection pipe 6, while a small portion enters metal wire mesh 3, as detailed below:

[0041] In this application, firstly, the paint mist from the perforated mesh 2 enters the equipment body 1;

[0042] Then, the spray pipe of the water spraying device 4 sprays water onto the paint mist passing through the perforated mesh 2 (a set of spray pipes is located between the perforated mesh 2 and the oil slinger 5) to dilute the paint mist and prevent the paint mist from being too viscous and adhering to the inside of the equipment body 1, resulting in the inability to collect or low collection efficiency.

[0043] Then, the paint is collected by the oil slinger 5, which completes the collection of most of the paint mist;

[0044] Meanwhile, a small portion of the remaining paint mist continues to move and passes through another set of spray pipes (the spray pipes located between the oil slinger 5 and the metal wire mesh 3) into the metal wire mesh 3 to recover the paint mist, supplementing the recovery of the remaining paint mist and ensuring comprehensive recovery.

[0045] Finally, the recycled paint is collected through collection pipe 6.

[0046] Instructions on how the oil slinger 5 rotates for recycling: The fixed plate 7 is fixedly connected to the equipment body 1. The fixed plate 7 has a rotating wheel 8 that is fixedly connected to the central shaft of the oil slinger 5. A belt 9 drives the two rotating wheels 8 on two adjacent fixed plates 7. An explosion-proof motor 10 is fixedly connected to the equipment body 1. The output shaft of the explosion-proof motor 10 is fixedly connected to one of the rotating wheels 8. A tensioning wheel 11 is rotatably connected to the fixed plate 7 and presses against the belt 9. The tensioning wheel 11 ensures stable transmission between the rotating wheel 8 and the belt 9.

[0047] The output shaft of the explosion-proof motor 10, located outside the main body of the equipment 1, rotates, causing the belt 9 to drive the rotating wheel 8 to rotate, which in turn drives the oil slinger 5 to rotate. The rotation directions of the multiple rotating wheels 8 are consistent, and the multiple oil slingers 5 rotate synchronously to recover most of the paint mist.

[0048] One of the rotating shafts 12 has an arc-shaped plate 19 fixedly connected to its end. The rotating shaft 12, which moves in a circular motion, drives the arc-shaped plate 19 to move in a circular motion. The arc-shaped plate 19 does not rotate relative to the rotating wheel 8. In conjunction with the oil slinger 5, it helps to recover paint mist. Through holes can be opened in the arc-shaped plate 19 to enhance air circulation.

[0049] A rotating shaft 12 is fixedly connected to the edge of the rotating wheel 8. A connecting rope 14 is rotatably connected to the rotating shaft 12. The connecting rope 14 is slidably engaged with the tensioning wheel 11. A fine division plate 15 located above the collecting tube 6 is rotatably connected to the bottom of the connecting rope 14. A sliding plate 16 is rotatably connected to the fine division plate 15.

[0050] The rotating wheel 8 drives the rotating shaft 12 to make a circular motion, which causes one end of the connecting rope 14 to make a circular motion, while the other end of the connecting rope 14 is rotatably connected to the subdivision plate 15. Under the action of gravity of the subdivision plate 15, the connecting rope 14 (non-elastic rope) slides back and forth along the tension wheel 11, and the corresponding subdivision plate 15 moves back and forth on the slide plate 16, which makes the paint on the subdivision plate 15 refine back and forth and prevents adhesion.

[0051] It is worth noting that the position of the rotating connection between the slide plate 16 and the subdivision plate 15 is close to one end of the subdivision plate 15, ensuring that the reciprocating distance of one end of the subdivision plate 15 is greater than that of the other end, thereby increasing the shaking efficiency.

[0052] The collection tube 6 is fixedly connected to a sleeve 17, which is slidably connected to a slide plate 16 via a tension spring. The subdivision plate 15 is rotatably connected to the slide plate 16. When the subdivision plate 15 reciprocates, the slide plate 16 slides up and down along the sleeve 17 under the action of the tension spring, thereby increasing the shaking efficiency of the subdivision plate 15.

[0053] A vertical rope 18 is fixedly connected between the top of the skateboard 16 and the connecting rope 14. When the connecting rope 14 moves up and down, it drives the vertical rope 18 to move up and down. The vertical rope 18 actively pulls the skateboard 16, and with the help of the tension spring, it further enhances the swaying amplitude of the subdivided plate 15. A maintaining plate 24 that fits against the vertical rope 18 is fixedly connected to the fixing plate 7 to ensure that the vertical rope 18 moves up and down smoothly and does not move at a large horizontal angle.

[0054] A horizontal plate 13 is rotatably connected between two adjacent rotating shafts 12. The rotating wheel 8 rotates on its own, causing the rotating shaft 12 to make circular motion. The two rotating shafts 12 that make circular motion synchronously keep the horizontal plate 13 horizontally distributed and vertically moving up and down (the horizontal plate 13 also moves back and forth in the horizontal direction and will not tilt). This ensures the synchronous rotation of the rotating wheel 8 and avoids slippage between the belt 9 and the rotating wheel 8 (slippage may occur between the belt 9 and the rotating wheel 8 under long-term operation and the influence of paint mist).

[0055] On the other hand, the horizontal plate 13 is provided with a sliding groove 20 for the connecting rope 14 to move. A pressure ball 21 is fixedly connected to the end of the sliding groove 20. When the connecting rope 14 moves back and forth, the horizontal plate 13 also moves back and forth, so that the pressure ball 21 presses against the connecting rope 14. The pressed connecting rope 14 bends and further pulls the end of the subdivision plate 15, aggravating the shaking of the subdivision plate 15.

[0056] It is worth noting that: the maintaining plate 24 and the vertical rope 18 both pass through the sliding groove 20, which further stabilizes the position of the vertical rope 18 and prevents the vertical rope 18 from tilting too much, affecting the sliding of the slide plate 16 in the sleeve 17. The sliding groove 20 is slidably fitted with a pressing block 22 located between the inclined connecting rope 14 and the vertical rope 18, which reduces the contact between the connecting rope 14 and the vertical rope 18, thereby ensuring the swaying of the subdivision plate 15.

[0057] The pressing block 22 has grooves on both sides, and ball bearings 23 move in the grooves. The ball bearings 23 rotate and slide in the grooves. The ball bearings 23 contact the sliding groove 20, which helps the pressing block 22 slide along the sliding groove 20. The ball bearings 23 that slide and rotate have a better sliding effect than the ball bearings 23 that only rotate.

[0058] An adjusting plate is slidably fitted onto the fixed plate 7. The adjusting plate is pressed and fixed to the fixed plate 7 by a threaded rod. The tension wheel 11 is rotatably connected to the adjusting plate, and the holding plate 24 is fixedly connected to the adjusting plate. By rotating the threaded rod, the end of the threaded rod moves away from the fixed plate 7. At this time, the adjusting plate can slide along the fixed plate 7. The sliding of the adjusting plate along the fixed plate 7 drives the tension wheel 11 and the holding plate 24 to move synchronously, thereby adjusting the pressing effect of the tension wheel 11 on the belt 9. After the adjustment is completed, by reversing the threaded rod, the end of the threaded rod presses against the fixed plate 7 again, so that the adjusting plate is fixed on the fixed plate 7.

[0059] Please see Figure 14 In this application, the paint mist purification device delivers paint mist to the separation device (device body 1) through a spray pipe. The collection pipe 6 at the bottom of the separation device is connected to a return water pipe, and the other end of the return water pipe is connected to the paint mist purification device. After multiple cycles of filtration and purification, the paint mist purification device recovers the paint into the recovery bucket through a recovery pump.
