[0002] It is known to those skilled in the art that there are odors and dust impurities in a coating workshop. Therefore, it is necessary to treat the gases and impurities in the air. In the existing gas purification technology, generally, formaldehyde in the air is purified by spraying a formaldehyde absorption liquid in combination with activated carbon adsorption. However, after the air enters the purification treatment box, it will float around randomly. When the formaldehyde in the air is absorbed by spraying, it is very difficult for the formaldehyde to mix with the sprayed formaldehyde absorption liquid. Moreover, the adsorption effect of the activated carbon in the purification treatment box on formaldehyde will deteriorate after long-term use. The method of manually replacing the activated carbon is not only cumbersome but also cannot be processed in time, which affects the purification effect of the purification treatment box on formaldehyde.

[0014] A purification system of a purification treatment system for a coating workshop, the steps of the purification system are as follows: S1: Load the formaldehyde absorption liquid at the bottom of the inner wall of the purification treatment tank. The water surface of the formaldehyde absorption liquid is lower than the top of the exhaust duct. Load activated carbon particles into the two storage chambers. S2: Start the exhaust fan to draw the air in the coating workshop into the purification treatment tank along the air inlet groove.

[0015] The beneficial effects of the present invention are as follows: 1.

[0016] 2. For the purification treatment system for a coating workshop described in the present invention, the drive assembly drives the guide vane to rotate to pat the air on the concave surfaces of the two second guide plates, so that the air enters the arc-shaped groove and mixes with the formaldehyde absorption liquid in the arc-shaped groove, thereby improving the purification effect of the formaldehyde absorption liquid on the air. And as the guide vane rotates, the formaldehyde absorption liquid in the arc-shaped groove keeps tumbling, facilitating the mixing of formaldehyde and the formaldehyde absorption liquid.

[0017] 3. For the purification treatment system for a coating workshop described in the present invention, the L-shaped plate separates the air and the formaldehyde absorption liquid for separate flow. Through the guidance of the third guide plate, the air collides with the formaldehyde absorption liquid accumulated at the bottom of the purification treatment tank, so that the air continues to react with the formaldehyde absorption liquid. And the formaldehyde absorption liquid falling on the third guide plate flows downward along the third guide plate and is cut into multiple strands by the shunt plate. The multiple strands of formaldehyde absorption liquid form a falling water curtain, and the air passes through the formaldehyde absorption liquid water curtain before entering the exhaust duct, thereby enabling the formaldehyde absorption liquid to further absorb the formaldehyde in the air.

[0018] 4.

Through the arranged first stop block, the air entering the air inlet groove is shunted to prevent the air from being too concentrated and not being easily absorbed by the activated carbon particles. The shunted air flows along the cross plate, enabling the air to flow to the deep part where the activated carbon particles are piled up, and preventing the air from directly passing through the activated carbon particles and being discharged from the ventilation groove.

Detailed Embodiments

[0021] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0022] As Figures 1 to 8As shown in the figure, the present invention provides a technical solution, a purification treatment system for a coating workshop, including a purification treatment box 1. An air inlet groove 2 is opened at the top of the purification treatment box 1. A suction fan 3 is fixedly connected to the bottom of the purification treatment box 1. The output end and the input end of the suction fan 3 are both connected with a suction duct 4. One end of one of the suction ducts 4 extends into the purification treatment box 1. A bottom plate 21 is fixedly connected to the inner wall of the purification treatment box 1. Two exhaust grooves 27 are symmetrically opened inside the bottom plate 21. Two second guide plates 20 are symmetrically and fixedly connected to the top of the bottom plate 21. Both of the two second guide plates 20 are fixedly connected to the purification treatment box 1. The second guide plates 20 are arranged in a waveform. Two first pipes 32 are symmetrically rotatably connected to the inner wall of the purification treatment box 1. A plurality of nozzles 33 are arranged on the outer walls of the two first pipes 32. One end of each of the two first pipes 32 penetrates through the purification treatment box 1 and is connected with a rotary joint 38. A water pump 34 is fixedly connected to the outer wall of the purification treatment box 1. The output end and the input end of the water pump 34 are both connected with a second pipe 35. One end of one of the second pipes 35 extends into the purification treatment box 1. One end of the other second pipe 35 is connected with a third pipe 36. Two fourth pipes 37 are symmetrically connected to both ends of the third pipe 36. The two fourth pipes 37 are respectively connected with the two rotary joints 38.

[0023] Through the above technical solution, the purification treatment box 1 is placed in the coating workshop. Formaldehyde absorption liquid is filled at the bottom of the inner wall of the purification treatment box 1. The water surface of the formaldehyde absorption liquid is lower than the top of the suction duct 4. The suction fan 3 is started to draw the air in the coating workshop into the purification treatment box 1 along the air inlet groove 2. The water pump 34 is started to draw the formaldehyde absorption liquid accumulated in the purification treatment box 1 along the second pipe 35, the third pipe 36, the fourth pipe 37, the rotary joint 38, and the first pipe 32 to the nozzles 33. The air entering the purification treatment box 1 is sprayed with formaldehyde absorption liquid through the nozzles 33, thereby absorbing the formaldehyde in the air and purifying the air. By arranging two second guide plates 20 in the purification treatment box 1, the air flows between the convex surfaces of the two second guide plates 20. The range of air flow is reduced by the two convex surfaces, so that the air is more concentrated in the purification treatment box 1, improving the mixing effect of the formaldehyde in the air and the formaldehyde absorption liquid. The air after spraying passes through the exhaust grooves 27 and flows downward, and is discharged back into the coating workshop along the suction duct 4. The formaldehyde absorption liquid sprayed and dropped passes through the exhaust grooves 27 and accumulates again at the bottom of the purification treatment box 1.

[0024] Specifically, two arc-shaped grooves 25 are symmetrically opened inside the bottom plate 21. Second rotating shafts 22 are rotatably connected to the inner walls of the two arc-shaped grooves 25. Sleeve barrels 23 are fixedly connected to the outer walls of the two second rotating shafts 22. Flow guide vanes 24 are equidistantly and fixedly connected to the outer walls of the two sleeve barrels 23. The flow guide vanes 24 are arranged in an arc shape. A driving assembly for cooperating with the flow guide vanes 24 is arranged on the outer wall of the purification treatment box 1.

[0025] Through the above technical solution, the formaldehyde absorption liquid falling by spraying first falls into the arc-shaped groove 25. The air flowing downward through the outer convex surfaces of the two second guide plates 20 enters the concave surfaces of the two second guide plates 20. The driving assembly drives the second rotating shaft 22 on the right to rotate clockwise, and the second rotating shaft 22 on the left rotates counterclockwise. Thus, the guide vane 24 on the right rotates clockwise, and the guide vane 24 on the left rotates counterclockwise. The rotating guide vane 24 pats the air on the concave surfaces of the two second guide plates 20, enabling the air to enter the arc-shaped groove 25 and mix with the formaldehyde absorption liquid in the arc-shaped groove 25. Thereby, the purification effect of the formaldehyde absorption liquid on the air is improved. Moreover, as the guide vane 24 rotates, the formaldehyde absorption liquid in the arc-shaped groove 25 continuously tumbles, facilitating the mixing of formaldehyde and the formaldehyde absorption liquid.

[0026] Specifically, drain grooves 26 are respectively opened inside the bottom plate 21 and at the bottoms of the two exhaust grooves 27. L-shaped plates 28 are fixedly connected to the inner walls of the two exhaust grooves 27. Two third guide plates 30 are symmetrically and fixedly connected to the bottom of the bottom plate 21. Both of the two third guide plates 30 are arc-shaped, and flow dividing plates 31 are fixedly connected to the tops of the two third guide plates 30 at equal intervals.

[0027] Through the above technical solution, as the nozzle 33 continuously sprays, the formaldehyde absorption liquid in the arc-shaped groove 25 continuously increases. When the water level of the formaldehyde absorption liquid in the arc-shaped groove 25 is flush with the top of the drain groove 26, the formaldehyde absorption liquid in the arc-shaped groove 25 flows downward along the drain groove 26 and lands on the third guide plate 30. At this time, since the bottom of the L-shaped plate 28 is submerged by the formaldehyde absorption liquid, the air can only flow along the top of the L-shaped plate 28. Thus, the air and the formaldehyde absorption liquid flow separately. The air flowing out from the exhaust groove 27 flows downward, and through the guiding of the third guide plate 30, the air impacts the formaldehyde absorption liquid at the bottom of the purification treatment box 1. Thereby, the air continues to react with the formaldehyde absorption liquid. Moreover, the formaldehyde absorption liquid landing on the third guide plate 30 flows downward along the third guide plate 30 and is cut into multiple strands by the flow dividing plates 31. The multiple strands of formaldehyde absorption liquid form a falling water curtain. The air passes through the formaldehyde absorption liquid water curtain before entering the exhaust duct 4. Thereby, the formaldehyde absorption liquid further absorbs formaldehyde in the air.

[0028] Specifically, the driving assembly includes a motor 45. The motor 45 is fixedly installed on the outer wall of the purification treatment box 1. The output end of the motor 45 extends into the purification treatment box 1 and is fixedly connected to one of the second rotating shafts 22. One end of each of the two second rotating shafts 22 penetrates the purification treatment box 1. Third gears 44 are fixedly connected to the outer walls of the two second rotating shafts 22, and the two third gears 44 are meshed with each other.

[0029] Through the above technical solution, the starting motor 45 is started to drive the second rotating shaft 22 on the right to rotate clockwise, so that the corresponding third gear 44 rotates clockwise, driving another third gear 44 to rotate counterclockwise, and the second rotating shaft 22 on the left rotates counterclockwise.

[0030] Specifically, the outer walls of both first pipelines 32 are fixedly connected with second gears 39. A slide plate 40 is slidably connected to the outer wall of the purification treatment tank 1. Two third racks 41 are symmetrically and fixedly connected to the bottom of the slide plate 40. The two third racks 41 are respectively meshed with the two second gears 39. One end of each of the two second rotating shafts 22 is fixedly connected with a crank 43. Connecting shafts 42 are rotatably connected to the outer walls of the two cranks 43. The two connecting shafts 42 are respectively rotatably connected to the two third racks 41.

[0031] Through the above technical solution, while the two second rotating shafts 22 rotate, they drive the two cranks 43 to rotate. When the two cranks 43 rotate to the upper side, through the provided connecting shafts 42, the two third racks 41 are pushed upward, driving the slide plate 40 to move upward. As the two third racks 41 move upward simultaneously, the two second gears 39 are driven to rotate simultaneously, causing the two spray heads 33 to swing downward simultaneously. When the two cranks 43 rotate to the lower side, through the provided connecting shafts 42, the two third racks 41 are pulled downward, driving the slide plate 40 to move downward. As the two third racks 41 move downward simultaneously, the two second gears 39 are driven to rotate simultaneously, causing the two spray heads 33 to swing upward simultaneously. Repeating this process, the two second rotating shafts 22 drive the two spray heads 33 to swing up and down while rotating, which is convenient for expanding the spraying range of the two spray heads 33, making the spraying range of the formaldehyde absorption liquid wider and improving the mixing effect with the air.

[0032] Specifically, two storage cavities 5 are symmetrically formed inside the purification treatment tank 1. A cover plate 6 is arranged on the top of the purification treatment tank 1 and is used in cooperation with the storage cavities 5. The bottoms of the inner walls of the two storage cavities 5 are both inclined surfaces. A blanking groove 10 is formed inside the purification treatment tank 1 and at the bottom of the storage cavity 5. A top plate 15 is fixedly connected to the inner wall of the purification treatment tank 1 and below the blanking groove 10. An air vent groove 16 is formed inside the top plate 15. A blanking assembly is arranged inside the purification treatment tank 1.

[0033] Through the above technical solution, activated carbon particles are loaded into the two storage cavities 5. Through the provided blanking assembly, the activated carbon particles slide down along the inclined surfaces of the inner walls of the storage cavities 5 into the blanking groove 10 and accumulate on the top plate 15. The air entering the purification treatment tank 1 is purified by the activated carbon particles accumulated on the top plate 15, absorbing formaldehyde in the air, and the air passing through the activated carbon particles continues to flow downward from the air vent groove 16.

[0034] Specifically, the blanking assembly includes two second racks 13, which are symmetrically arranged inside the purification treatment tank 1 and are both slidably connected to the purification treatment tank 1. Second baffles 14 are fixedly connected to the bottoms of the two second racks 13. The two second baffles 14 are attached to both sides of the top plate 15. The top of the top plate 15 is provided with symmetrical inclined surfaces. Two electric telescopic rods 7 are symmetrically and fixedly connected inside the purification treatment tank 1. The output ends of the two electric telescopic rods 7 are both fixedly connected with first racks 8. The two first racks 8 are both slidably connected to the purification treatment tank 1. First baffles 9 are fixedly connected to the ends of the two first racks 8 that are close to each other. The first baffles 9 are used in cooperation with the blanking grooves 10. A sealing groove for using the first baffle 9 is opened inside the purification treatment tank 1. Two first rotating shafts 11 are symmetrically and fixedly connected inside the purification treatment tank 1. First gears 12 are rotatably connected to the outer walls of the two first rotating shafts 11. The first racks 8 and the second racks 13 are both meshed with the first gears 12. A box door 46 is arranged on the outer wall of the purification treatment tank 1.

[0035] Through the above technical solution, by providing the two second baffles 14 and cooperating with the top plate 15, an activated carbon accumulation cavity is formed. The activated carbon particles falling from the blanking groove 10 accumulate between the two second baffles 14 to purify the air entering the purification treatment tank 1. After a period of purification, the two electric telescopic rods 7 are pushed to make the two first racks 8 approach each other, so that the two first baffles 9 are respectively inserted into the two blanking grooves 10 to seal the two blanking grooves 10 and prevent the activated carbon particles in the storage cavity 5 from falling. While the two first racks 8 approach each other, through the two first gears 12 provided, the two second racks 13 are driven to move downward simultaneously, so that the two second baffles 14 move downward simultaneously. After losing the blockage of the two second baffles 14, the activated carbon particles on the top plate 15 slide down along the inclined surface of the top plate 15 and accumulate on the top of the second deflector 20. Subsequently, the two electric telescopic rods 7 are pulled to make the two first racks 8 move away from each other, driving the two first baffles 9 to move away from each other, so that the two blanking grooves 10 are opened. At this time, the activated carbon particles in the storage cavity 5 can fall on the top plate 15 again along the blanking groove 10. While the two first racks 8 move away from each other, through the two first gears 12 provided, the two second racks 13 are driven to move upward simultaneously, so that the two second baffles 14 move upward simultaneously to block the top plate 15 again. Thus, the replacement of the activated carbon particles on the top plate 15 is completed, and the absorption effect of the activated carbon particles is maintained. The purification treatment tank 1 can be opened through the provided box door 46, which is convenient for taking out the used activated carbon particles.

[0036] Specifically, a first stop block 17 is fixedly connected to the inner wall of the purification treatment tank 1. The first stop block 17 is located at the bottom of the inner wall of the air inlet groove 2. The longitudinal section of the first stop block 17 is an isosceles triangle. A cross plate 18 is fixedly connected to the bottom of the first stop block 17.

[0037] Through the above technical solution, by providing the first stop block 17, the air entering the air inlet groove 2 is shunted, preventing the air from being too concentrated and thus difficult to be absorbed by the activated carbon particles. The shunted air flows along the cross plate 18, thereby enabling the air to flow to the deep part where the activated carbon particles are piled up, and preventing the air from directly passing through the activated carbon particles and discharging from the ventilation groove 16.

[0038] Specifically, two first guide plates 19 are symmetrically and fixedly connected to the bottom of the top plate 15. Both of the two first guide plates 19 are inclinedly installed. The bottoms of the two first guide plates 19 are respectively fixedly connected to two second guide plates 20. Inside the purification treatment box 1 and between the two second guide plates 20, a second stop block 29 is fixedly connected. The longitudinal section of the second stop block 29 is an isosceles triangle.

[0039] Through the above technical solution, by providing the first guide plates 19 and cooperating with the second guide plates 20, the activated carbon particles falling from the top plate 15 can be collected. Moreover, through the inclined surface at the bottom of the first guide plate 19, the air can be guided to flow downward. By providing the second stop block 29, the area between the two second guide plates 20 is reduced, making the air more concentrated, facilitating the contact between the sprayed formaldehyde absorption liquid and the air. Also, in cooperation with the bottom of the second stop block 29, the air accumulated at the arc-shaped groove 25 is blocked, preventing the air from flowing upward after being slapped by the guide vanes 24.

[0040] A purification system for a coating workshop purification treatment system, and the steps of this purification system are as follows: S1: Load the formaldehyde absorption liquid at the bottom of the inner wall of the purification treatment box 1. The water surface of the formaldehyde absorption liquid is lower than the top of the exhaust duct 4, and load the activated carbon particles into the two storage chambers 5. S2: Start the exhaust fan 3, draw the air in the coating workshop into the purification treatment box 1 along the air inlet groove 2. Start the spray head 33 to spray the formaldehyde absorption liquid on the air entering the purification treatment box 1. Control the spray head 33 to swing up and down through the motor 45, and control the guide vanes 24 to rotate to slap the air on the concave surfaces of the two second guide plates 20. The purified air is discharged back into the coating workshop along the exhaust duct 4. S3: Use the electric telescopic rod 7 to control the feeding chute 10 to open and close regularly to complete the replacement of the activated carbon particles on the top plate 15.

[0041] During use, place the purification treatment box 1 in the coating workshop. Load the formaldehyde absorption liquid at the bottom of the inner wall of the purification treatment box 1. The water surface of the formaldehyde absorption liquid is lower than the top of the exhaust duct 4. Start the exhaust fan 3 to draw the air in the coating workshop into the purification treatment box 1 along the air inlet groove 2. Load activated carbon particles in the two storage cavities 5. The activated carbon particles slide down along the inclined surface of the inner wall of the storage cavity 5 into the feeding trough 10 and accumulate on the top plate 15. Through the two second baffles 14 provided, in cooperation with the top plate 15, an activated carbon accumulation cavity is formed. The activated carbon particles falling from the feeding trough 10 accumulate between the two second baffles 14 to purify the air entering the purification treatment box 1. Through the first stop block 17 provided, the air entering the air inlet groove 2 is shunted to prevent the air from being too concentrated and not being easily absorbed by the activated carbon particles. The shunted air flows along the cross plate 18, so that the air flows to the deep part where the activated carbon particles are accumulated, preventing the air from directly passing through the activated carbon particles and discharging from the ventilation groove 16. The air passing through the activated carbon particles continues to flow downward from the ventilation groove 16. Start the water pump 34 to pump the formaldehyde absorption liquid accumulated in the purification treatment box 1 along the second pipeline 35, the third pipeline 36, the fourth pipeline 37, the rotary joint 38, and the first pipeline 32 to the nozzle 33. Spray the formaldehyde absorption liquid on the air entering the purification treatment box 1 through the nozzle 33 to absorb the formaldehyde in the air and purify the air. Start the motor 45 to drive the second rotating shaft 22 on the right to rotate clockwise, so that the corresponding third gear 44 rotates clockwise, driving the other third gear 44 to rotate counterclockwise, and the second rotating shaft 22 on the left rotates counterclockwise. While the two second rotating shafts 22 are rotating, drive the two rocker arms 43 to rotate. When the two rocker arms 43 rotate to the upper side, through the connecting shaft 42 provided, push the two third rack bars 41 to move upward, driving the slide plate 40 to move upward. As the two third rack bars 41 move upward simultaneously, drive the two second gears 39 to rotate simultaneously, so that the two nozzles 33 swing downward simultaneously. When the two rocker arms 43 rotate to the lower side, through the connecting shaft 42 provided, pull the two third rack bars 41 to move downward, driving the slide plate 40 to move downward. As the two third rack bars 41 move downward simultaneously, drive the two second gears 39 to rotate simultaneously, so that the two nozzles 33 swing upward simultaneously. Thus, reciprocatingly, while the two second rotating shafts 22 are rotating, drive the two nozzles 33 to swing up and down, which is convenient for increasing the spraying range of the two nozzles 33, making the spraying range of the formaldehyde absorption liquid wider and improving the mixing effect with the air. Through the two second guide plates 20 provided in the purification treatment box 1, the air flows between the convex surfaces of the two second guide plates 20. By the two convex surfaces, the range of air flow is reduced, making the air more concentrated in the purification treatment box 1 and improving the mixing effect between the formaldehyde in the air and the formaldehyde absorption liquid. The formaldehyde absorption liquid sprayed and falling first falls into the arc-shaped groove 25. The air passing through the convex surfaces of the two second guide plates 20 flows downward and enters the concave surfaces of the two second guide plates 20. The second rotating shaft 22 on the right rotates clockwise,The second rotating shaft 22 on the left rotates counterclockwise, thereby causing the deflector blades 24 on the right to rotate clockwise and the deflector blades 24 on the left to rotate counterclockwise. The rotating deflector blades 24 slap the air on the concave surfaces of the two second deflector plates 20, causing the air to enter the arc-shaped groove 25 and mix with the formaldehyde absorbent liquid in the arc-shaped groove 25, thereby enhancing the purification effect of the formaldehyde absorbent liquid on the air. As the deflector blades 24 rotate, the formaldehyde absorbent liquid in the arc-shaped groove 25 continuously tumbles, facilitating the mixing of formaldehyde with the formaldehyde absorbent liquid. Through the provided second stopper 29, the air accumulated at the arc-shaped groove 25 is blocked to prevent the air from flowing upward after being slapped by the deflector blades 24. As the nozzle 33 continuously sprays, the formaldehyde absorbent liquid in the arc-shaped groove 25 continuously increases. When the water level of the formaldehyde absorbent liquid in the arc-shaped groove 25 is flush with the top of the drain groove 26, the formaldehyde absorbent liquid in the arc-shaped groove 25 flows downward along the drain groove 26 and lands on the third deflector plate 30. At this time, since the bottom of the L-shaped plate 28 is submerged by the formaldehyde absorbent liquid, the air can only flow along the top of the L-shaped plate 28, thereby separating the air from the formaldehyde absorbent liquid. The air flowing out from the exhaust groove 27 flows downward. Through the guidance of the third deflector plate 30, the air collides with the formaldehyde absorbent liquid at the bottom of the purification treatment box 1, thereby enabling the air to continue to react with the formaldehyde absorbent liquid. Moreover, the formaldehyde absorbent liquid landing on the third deflector plate 30 flows downward along the third deflector plate 30 and is cut into multiple strands by the flow splitter plate 31. The multiple strands of formaldehyde absorbent liquid form a falling water curtain. The air passes through the formaldehyde absorbent liquid water curtain before entering the exhaust duct 4, thereby enabling the formaldehyde absorbent liquid to further absorb the formaldehyde in the air. After a period of purification, the two electric telescopic rods 7 are used to push the two first racks 8 closer to each other, causing the two first baffles 9 to be inserted into the two feeding slots 10 respectively to seal the two feeding slots 10 and prevent the activated carbon particles from falling. While the two first racks 8 are approaching each other, through the two provided first gears 12, the two second racks 13 are driven to move downward simultaneously, causing the two second baffles 14 to move downward simultaneously. After losing the block of the two second baffles 14, the activated carbon particles on the top plate 15 slide down along the inclined surface on the top plate 15. Through the provided first deflector plate 19, in cooperation with the second deflector plate 20, the activated carbon particles falling from the top plate 15 can be collected. Subsequently, the two electric telescopic rods 7 are used to pull the two first racks 8 away from each other, driving the two first baffles 9 away from each other, and opening the two feeding slots 10. At this time, the activated carbon particles in the storage cavity 5 can fall onto the top plate 15 again along the feeding slots 10. While the two first racks 8 are moving away from each other, through the two provided first gears 12, the two second racks 13 are driven to move upward simultaneously, causing the two second baffles 14 to move upward simultaneously to block the top plate 15 again, thereby completing the replacement of the activated carbon particles on the top plate 15 and maintaining the absorption effect of the activated carbon particles. The purified air is discharged back into the coating workshop along the exhaust duct 4 to improve the air quality of the coating workshop.,
