Description

Technical Field

[0001] The invention relates to the technical field of paint mist recovery structures, in particular to a paint mist filtering and recovery system. Background Art

[0002] In traditional paint mist treatment technology, paint mist collection and recovery mainly rely on simple filtering devices with a single filtering method (simple filter mesh), which has some obvious shortcomings; On the one hand, paint mist has a high viscosity and is easy to adhere to the filter material, making it difficult to handle paint mist with high viscosity, resulting in a decrease in filtration efficiency and the need to frequently replace the filter material. On the other hand, paint mist contains a large amount of harmful substances, and direct discharge will seriously pollute the environment. Existing recycling technology can often only recycle part of the paint mist, and the recycling effect is unstable, resulting in a low recovery rate of paint mist and increased processing costs.

[0003] To this end, we propose a paint mist filtration and recovery system. Summary of the Invention

[0004] The object of the present invention is to provide a paint mist filtering and recovery system to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned object, the present invention provides a paint mist filtration and recovery system, comprising a paint mist purification device, wherein the paint mist purification device transports the paint mist to a separation device through a spray pipe, a return pipe is sleeved at the bottom of the separation device, and the other end of the return 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; The separation device includes a device body, one end of which is provided with a perforated mesh and the other end is provided with a wire mesh. A water spray device for diluting the viscosity of the paint mist is provided on the top of the device body. An oil-spinning pan is rotatably connected to the inside of the device body. The bottom of the device body is connected to a collection pipe. The paint mist first passes through the perforated mesh, then is processed by the water spray device and enters the oil-spinning pan. Most of it is collected into the collection pipe, and a small part enters the wire mesh. It also includes: a fixed plate connected and fixed to the equipment body, a rotating wheel connected and fixed to the central axis of the oil-slinging plate is rotatably provided on the fixed plate, a belt is transmitted between the two rotating wheels on two adjacent fixed plates, an explosion-proof motor is fixedly connected to the equipment body, the output shaft of the explosion-proof motor is connected and fixed to one of the rotating wheels, and a tensioning wheel is rotatably connected to the fixed plate and press-fits with the belt.

[0006] A rotating shaft is fixedly connected to the edge of the rotating wheel, a horizontal plate is rotatably connected between two adjacent rotating shafts, a connecting rope is rotatably connected to the rotating shaft, the connecting rope is slidably engaged with the tensioning wheel, and the bottom of the connecting rope is rotatably connected to a subdivision plate located above the collection pipe, and a slide plate is rotatably connected to the subdivision plate.

[0007] Furthermore, a sleeve is fixedly connected to the interior of the collecting tube, and the sleeve is slidably connected to the slide via a tension spring. The subdivision plate is rotatably connected to the slide, so that the reciprocating subdivision plate moves up and down at the same time.

[0008] Furthermore, the position of the rotation 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.

[0009] Furthermore, a vertical rope is fixedly connected between the top of the skateboard and the connecting rope, which cooperates with the tension spring and the sleeve to drive the skateboard to move up and down, and drives the subdivision board to move up and down while shaking.

[0010] Furthermore, a maintaining plate that fits the vertical rope is fixedly connected to the fixing plate to ensure stable movement of the vertical rope.

[0011] Furthermore, one of the ends of the rotating shaft is fixedly connected with an arc-shaped plate to enhance the recycling effect.

[0012] Furthermore, the horizontal plate is provided with a sliding groove for the connecting rope to move, and the end of the sliding groove is fixedly connected to a pressing ball, so that the horizontal plate can move to act on the connecting rope to facilitate shaking.

[0013] Furthermore, the maintaining plate and the vertical rope both pass through the sliding groove, and a pressure block is slidably fitted in the sliding groove between the inclined connecting rope and the vertical rope to limit the distance between the connecting rope and the vertical rope.

[0014] Furthermore, the fixed plate is slidably fitted with an adjustment plate, the adjustment plate is fixed to the fixed plate by a threaded rod, the tensioning wheel is rotatably connected to the adjustment plate, and the maintaining plate is fixedly connected to the adjustment plate to adjust the pressure of the tensioning wheel on the belt.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The paint mist in this application enters the device body from the perforated mesh, and water is sprayed on the paint mist passing through the perforated mesh through the spray pipe of the water spray device to dilute the paint mist and prevent the paint mist from being too viscous and adhering to the inside of the device body, resulting in inability to collect or low collection efficiency; Most of the paint mist is collected through the oil-slinging pan, and a small amount of residual paint mist is recovered through the wire mesh to ensure comprehensive recovery and ultimately achieve efficient and stable paint mist recovery.

[0016] The rotating wheel makes one end of the connecting rope do circular motion through the rotating shaft, and the other end involves the subdivision plate to rotate and connect, so that the subdivision plate can do reciprocating movement on the skateboard to refine the paint and prevent adhesion. The vertical rope that moves up and down actively pulls the skateboard, and cooperates with the tension spring to further increase the shaking amplitude of the subdivision plate.

[0019] 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.

[0020] See also Figures 1-13 The present invention provides a paint mist filtering and recovery system, comprising an equipment body 1, wherein a perforated mesh 2 is provided at one end of the equipment body 1 (the perforated mesh 2 preliminarily filters larger paint mist particles), and a wire mesh 3 is provided at the other end (the wire mesh 3 serves as a secondary filter to capture smaller paint mist particles). A water spray device 4 for diluting the viscosity of the paint mist is provided on the top of the equipment body 1, and an oil-slinging pan 5 is rotatably connected to the interior of the equipment body 1 (the oil-slinging pan 5 collects more paint mist through its rotational action, reduces the escape of paint mist, and is conducive to the further separation and recovery of the paint mist). A collection pipe 6 is connected to the bottom of the equipment body 1; The paint mist first passes through the perforated mesh 2, then is processed by the water spray device 4 and enters the oil-spinning pan 5. Most of it is collected and enters the collection pipe 6, and a small part enters the wire mesh 3. The details are as follows: In this application, first, the paint mist enters the device body 1 from the punching mesh 2; Then, the spray pipes of the water spray device 4 spray water on the paint mist passing through the perforated mesh 2 (a group of spray pipes is located between the perforated mesh 2 and the oil-spinning pan 5) to dilute the paint mist and prevent the viscosity of the paint mist from being too high and adhering to the inside of the equipment body 1, resulting in inability to collect or low collection efficiency; Then, the paint is collected by the oil-spinning pan 5, which completes the collection of most of the paint mist; At the same time, a small part of the remaining paint mist continues to move and passes through another set of spray pipes (the spray pipes located between the oil-spinning tray 5 and the metal mesh 3) and enters the metal mesh 3 to recover the paint mist, thereby supplementing the recovery of the remaining paint mist and ensuring comprehensive recovery. Finally, the recovered paint is collected through the collection pipe 6.

[0021] Explanation on how the oil-slinging pan 5 rotates for recycling: a fixed plate 7 is fixedly connected to the equipment body 1, and a rotating wheel 8 fixedly connected to the central axis of the oil-slinging pan 5 is rotatably mounted on the fixed plate 7. A belt 9 is transmitted between the two rotating wheels 8 on two adjacent fixed plates 7. An explosion-proof motor 10 is fixedly connected to the equipment body 1, and 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 is pressed against the belt 9. The tensioning wheel 11 ensures stable transmission between the rotating wheel 8 and the belt 9. The output shaft of the explosion-proof motor 10 arranged outside the equipment body 1 rotates, causing the belt 9 to transmit the power, and the rotating wheel 8 to rotate, thereby driving the oil-slinging plate 5 to rotate. The clockwise rotation direction of multiple rotating wheels 8 is consistent, and multiple oil-slinging plates 5 rotate synchronously to recover most of the paint mist; One end of the rotating shaft 12 is fixedly connected to an arc-shaped plate 19. The circular motion of the rotating shaft 12 drives the arc-shaped plate 19 to perform circular motion. The arc-shaped plate 19 does not rotate relative to the rotating wheel 8. In conjunction with the oil-slinging pan 5, it helps to recover the paint mist. A through hole can be opened in the arc-shaped plate 19 to enhance air circulation.

[0022] The edge of the rotating wheel 8 is fixedly connected to a rotating shaft 12, and a connecting rope 14 is rotatably connected to the rotating shaft 12. The connecting rope 14 is slidably engaged with the tensioning wheel 11. The bottom of the connecting rope 14 is rotatably connected to a subdividing plate 15 located above the collecting pipe 6, and a slide plate 16 is rotatably connected to the subdividing plate 15. The rotating wheel 8 drives the rotating shaft 12 to make a circular motion, thereby making one end of the connecting rope 14 make a circular motion, and the other end of the connecting rope 14 is rotatably connected to the subdividing plate 15. Under the action of the gravity of the subdividing plate 15, the connecting rope 14 (non-elastic rope) slides back and forth along the tensioning wheel 11, and the corresponding subdividing plate 15 makes a reciprocating movement on the slide plate 16, so that the subdividing plate 15 reciprocates to refine the paint to prevent adhesion; It is noteworthy that the position of the rotational connection between the slide plate 16 and the subdividing plate 15 is close to one end of the subdividing plate 15, ensuring that the reciprocating distance of one end of the subdividing plate 15 is greater than that of the other end, thereby increasing the shaking efficiency.

[0023] The collecting pipe 6 is fixedly connected to a sleeve 17, which is slidably connected to the slide 16 via a tension spring. The subdividing plate 15 is rotatably connected to the slide 16. When the subdividing plate 15 reciprocates, the slide 16 slides up and down along the sleeve 17 under the action of the tension spring, thereby increasing the shaking efficiency of the subdividing plate 15. A vertical rope 18 is fixedly connected between the top of the slide 16 and the connecting rope 14. When the connecting rope 14 moves back and forth, it drives the vertical rope 18 to move up and down. The vertical rope 18 that moves up and down actively pulls the slide 16, and cooperates with the tension spring to further enhance the swing amplitude of the subdivision plate 15. Among them, a maintaining plate 24 that fits with the vertical rope 18 is fixedly connected to the fixed plate 7 to ensure that the vertical rope 18 moves up and down smoothly without too large a horizontal angle movement.

[0024] Among them, a horizontal plate 13 is rotatably connected between two adjacent rotating shafts 12. The rotating wheel 8 rotates, causing the rotating shaft 12 to make a circular motion. The two rotating shafts 12 that make a synchronous circular motion enable the horizontal plate 13 to maintain a horizontal distribution and vertical up and down movement (the horizontal plate 13 also reciprocates in the horizontal direction, and the horizontal plate 13 will not tilt). On the one hand, it ensures the synchronous rotation of the rotating wheel 8 and avoids the slippage of the belt 9 and the rotating wheel 8 (under the influence of long-term action and paint mist, slippage occurs between the belt 9 and the rotating wheel 8); On the other hand, the horizontal plate 13 is provided with a sliding groove 20 for the movement of the connecting rope 14, and the end of the sliding groove 20 is fixedly connected to a pressing ball 21. When the connecting rope 14 reciprocates, the horizontal plate 13 also reciprocates, causing the pressing ball 21 to press the connecting rope 14, and the pressed connecting rope 14 bends, further pulling the end of the subdivision plate 15, thereby aggravating the shaking of the subdivision plate 15.

[0025] It is worth noting that the maintaining plate 24 and the vertical rope 18 both pass through the sliding groove 20, further stabilizing the position of the vertical rope 18 and preventing the vertical rope 18 from tilting excessively and 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, reducing the contact between the connecting rope 14 and the vertical rope 18, thereby ensuring the shaking of the subdivision plate 15. Slide grooves are provided on both sides of the pressure block 22, and balls 23 are movable in the slide grooves. The balls 23 rotate and slide in the slide grooves. The balls 23 contact the sliding grooves 20, which helps the pressure block 22 to slide along the sliding grooves 20. The sliding and rotating balls 23 have a better sliding effect than the balls 23 that only rotate.

[0026] The fixing plate 7 is fitted with an adjusting plate by sliding, and the adjusting plate is pressed and fixed to the fixing plate 7 by a threaded rod, the tensioning wheel 11 is rotatably connected to the adjusting plate, and the maintaining plate 24 is fixedly connected to the adjusting plate; by rotating the threaded rod, the end of the threaded rod is moved away from the fixing plate 7, and the adjusting plate can slide along the fixing plate 7 at this time, and the adjusting plate slides along the fixing plate 7, driving the tensioning wheel 11 and the maintaining plate 24 to move synchronously, thereby adjusting the pressure effect of the tensioning wheel 11 on the belt 9. When the adjustment is completed, the end of the threaded rod is pressed against the fixing plate 7 again by reversing the threaded rod, so that the adjusting plate is fixed to the fixing plate 7.

[0027] See also Figure 14 The paint mist purification equipment in this application transports the paint mist to the separation equipment (equipment body 1) through a spray pipe. The collecting pipe 6 at the bottom of the separation equipment is connected with a return pipe, and the other end of the return pipe is connected to the paint mist purification equipment. After multiple cycles of filtration and purification, the paint mist purification equipment recovers the paint into the recovery barrel through a recovery pump.
