Description

Technical Field

[0001] The present invention relates to the technical field of waste gas treatment, and more particularly to an environmentally friendly waste gas treatment device for surface painting of electromechanical equipment. Background Art

[0002] In the manufacturing process of electromechanical equipment, surface painting is an indispensable step. However, a large amount of waste gas is generated during the painting process. These waste gases mainly contain volatile organic compounds (VOCs), paint mist particles, and other harmful substances. If directly discharged into the atmosphere without treatment, it will not only cause serious environmental pollution but also pose a threat to human health. Therefore, developing an efficient and environmentally friendly waste gas treatment device is crucial for the sustainable development of the electromechanical equipment manufacturing industry.

[0003] After the applicant's search, it was found that the waste gas from painting contains a large amount of paint particles. These tiny paint particles suspended in the air not only cause air pollution and affect air quality but may also enter the human body through the respiratory tract, irritating and damaging the respiratory system. Long-term exposure may even lead to occupational diseases such as allergic asthma and chronic bronchitis. In addition, the paint mist particles will adhere to the surrounding environment and the surface of objects, forming stains that are difficult to remove, affecting the appearance and hygiene. For the electromechanical equipment manufacturing industry, this not only concerns the company's environmental protection image and social responsibility but also directly affects the health of employees and the sustainability of the production environment. Therefore, the existing treatment devices will use wet curtain adsorption for treatment.

[0004] In the existing wet curtain treatment device, after the water in the water tank flows back through the wet curtain, paint particles will gradually accumulate on the surface and need to be cleaned. Traditional manual cleaning is rather inconvenient. In the water curtain spraying chamber for spraying the outer surface of a water pump disclosed in Patent CN112044648A, a balloon is arranged in the water tank, and the inflation or deflation of the balloon by an external air pump can achieve the rise and fall of the water level in the water tank. At the same time, the balloon is inflated by the external air pump to make the balloon expand, and the expanded balloon is extended into the water body. Since the hydrophobic groups in the paint will make the paint float on the upper surface of the water body and thus adhere to the surface of the balloon, and then the water level in the water tank is lowered to separate the water body in the water tank from the floating paint. However, in the above solution, although the balloon can contact the water surface to adsorb the floating paint particles after expansion, this physical adsorption method has low efficiency, especially insufficient capturing ability for micro particles. The paint particles may slide back into the water due to water flow or bubble disturbance. At the same time, the adsorption force of the balloon material itself on the paint particles is limited. Especially when the paint particles contain more hydrophobic groups and have a large surface tension, the paint particles are likely to fall off from the surface of the balloon and cannot be effectively fixed and collected. And although the water body and the paint particles can be separated by adjusting the water level, the paint adsorbed on the surface of the balloon still needs to be manually taken out and cleaned after reaching a certain amount, and this process is still cumbersome and may involve direct contact with harmful substances.

[0005] Therefore, the inventor particularly needs to design an exhaust gas environmental protection treatment device for spraying the surface of electromechanical equipment to solve the above technical problems. Summary of the Invention

[0006] The purpose of the present invention is to provide an exhaust gas environmental protection treatment device for spraying the surface of electromechanical equipment to solve the problems raised in the above background technology.

[0007] To solve the above technical problems, the present invention provides an environmental protection device for treating waste gas in the surface painting of electromechanical equipment, including: a water tank, a wet curtain chamber is installed on the top of the water tank, and a water pump is installed on one side of the water tank to input clean water into the wet curtain inside the wet curtain chamber. An oil absorption part is installed on the water tank, and a water lifting part and an oil absorption part are installed inside the water tank. The oil absorption part includes two outer shafts installed on brackets on both sides of the water tank, and two inner shafts installed at the top end inside the water tank. The outer shaft and the inner shaft are jointly connected to a conveyor belt, and a rubber pad is bonded to the conveyor belt. The water tank installs an oil absorption paper roll above the conveyor belt through rollers by two support plates, and a main pressing cylinder is rotatably installed on the connecting plate on the side of the two support plates. The water lifting part includes a motor installed on the side of the water tank. The motor is connected to a lead screw rotatably installed inside the water tank. The lead screw is threadedly connected to a moving block, and two cross bars fixed to the inner side of the water tank pass through the moving block to form a sliding connection. Cylinders are fixed on both sides of the moving block, and the cylinders slide in the lifting plate clamping grooves slidably connected up and down on the inner wall of the water tank. The clamping grooves form two troughs with different heights through an inclined channel. A lifting box is fixedly installed on the top of the lifting plate. The lifting box is located below the conveyor belt. An air inlet pipe is installed on one side of the water tank away from the lifting box. One of the cylinders passes through the opening on the side of the water tank and is connected to an outer shaft through a driving part. The driving part is used to drive the outer shaft to rotate when the lifting box is lifted.

[0008] Further, the driving part includes an inner rod fixedly connected to the cylinder extending out of the water tank. The inner rod slides in the opening on one side of the cylinder rod. The driving rod is rotatably installed at the top of the cylinder rod. The driving rod is rotatably installed at the bottom of the lifting rod. The lifting rod passes through the support plate on the side of the outer shaft bracket. Two guide rods are also fixed to the top of the support plate. The top of the lifting rod is connected to a rack plate. The guide rods pass through the rack plate to form a sliding connection. The rack plate meshes with a gear. The gear is installed on the side of the driving circular plate. The driving circular plate is connected to the rotating shaft of an outer shaft through a connecting shaft.

[0009] Further, the driving circular plate includes an inner circular plate and an outer circular plate. The inner circular plate is rotatably installed in the circular opening at the side end of the outer circular plate. Openings are provided on both sides of the inner circular plate. A resisting plate is rotatably installed in the openings. The resisting plate and the inner circular plate opening are connected by a spring. The outer circular plate is connected to the rotating shaft of an outer shaft through a connecting shaft. The resisting plate can be fitted into the fitting grooves annularly distributed on the inner wall of the circular opening of the outer circular plate, and at this time, the resisting plate rotates to the maximum angle away from the inner circular plate.

[0010] Further, L-shaped plates are installed on the bottom surface and three side surfaces inside the water tank. The L-shaped plates cover the lifting plate inside, and the top of the lifting plate is connected to the bottom of the lifting box through four vertical rods. The vertical rods are hermetically inserted and slidably connected to the L-shaped plates;

[0011] One of the cylinders passes through the opening on the side of the water tank and is located inside the L-shaped plate.

[0012] Further, a paper scraping part is installed on one side of the water tank, which includes a collection box and a scraping plate. The collection box is attached to the side wall of the water tank. The scraping plate is connected to the top of the collection box through a connecting rod, and the other end of the scraping plate is attached to a rubber pad in a vertical state, that is, this part of the rubber pad is located between two vertically aligned outer shafts.

[0013] Further, a cleaning part is installed on the top of the water tank. The cleaning part includes a glue removing box fixed on the top of the water tank. The glue removing box is provided with an opening through which a conveyor belt passes. An electric heating tube is installed inside the glue removing box, and a cleaning brush is rotatably installed. An inclined baffle is fixed on the inner wall of the glue removing box. The baffle is attached to the conveyor belt and the rubber pad. A drainage pipe penetrates through one side of the glue removing box, and the air inlet end of the drainage pipe penetrates into the water tank.

[0014] Further, the rotating shaft of the cleaning brush is connected to a pulley rotatably installed on the side of the glue removing box. The pulley is connected to the rotating shaft of the outer circular plate and the outer shaft through a belt. The rotating shaft and two circular plates can limit the coiled belt.

[0015] Further, a glue applying part is installed on one side of the water tank. The glue applying part includes a constant temperature glue storage box fixed on the side wall of the water tank. A glue pumping pump is arranged on the top of the constant temperature glue storage box. The output end of the glue pumping pump is connected to a glue spraying pipe installed between connecting plates. A row of nozzles is arranged on the top of the glue spraying pipe, below the oil absorbing paper being transported. The main pressing cylinder is installed between these connecting plates;

[0016] Further, a row of auxiliary pressing cylinders is rotatably connected between the side end support plates of the bracket with two outer shafts installed at one end.

[0017] Further, both ends of the rubber pad are designed in an arc shape. Therefore, both sides of the main pressing cylinder are also designed in an arc shape. At the same time, both sides of the oil absorbing paper attached to the rubber pad are also in an arc shape, but do not contact the conveyor belt. The baffle is provided with a bayonet corresponding to the rubber pad.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. By combining the lifting box with the movable oil absorbing paper, the present invention can efficiently adsorb the paint particles floating on the water surface. Compared with the physical adsorption of balloons in the comparative technology, this device has a stronger ability to capture tiny particles, improves the removal efficiency of paint particles, and the motor drives the lifting box to lift and the conveyor belt to rotate, realizing the automatic replacement of the oil absorbing paper and the continuous treatment of paint particles, without the need for replacement, reducing manual operation and improving work efficiency.

[0020] 2.

[0036] Now, the present invention will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic way, so they only show the components related to the present invention.

[0037] As Figures 1-11As shown in the figure, an environmental protection treatment device for waste gas in the surface painting of electromechanical equipment according to the present invention includes a water tank 1. A wet curtain chamber 11 is installed on the top of the water tank 1, and a water pump 12 is installed on one side of the water tank 1 to input clear water into the wet curtain inside the wet curtain chamber 11. An oil absorption part 2 is installed on the water tank 1, and a water lifting part 3 is installed inside the water tank 1. The oil absorption part 2 includes two outer shafts 21 installed on the brackets on both sides of the water tank 1 and two inner shafts 22 installed at the top end inside the water tank 1. The outer shaft 21 and the inner shaft 22 are jointly connected to a conveyor belt 23. The conveyor belt 23 passes through the openings at both ends of the water tank 1. A rubber pad 25 is adhered to the conveyor belt 23. The water tank 1 installs an oil absorption paper roll 26 through rollers above the conveyor belt 23 through two support plates, and a main pressing cylinder 27 is rotatably installed on the connecting plates on the side parts of the two support plates. The water lifting part 3 includes a motor 31 installed on the side of the water tank 1. The motor 31 is connected to a lead screw 32 rotatably installed inside the water tank 1. The lead screw 32 is threadedly connected to a moving block 33. Two cross bars 34 fixed to the inner side of the water tank 1 pass through the moving block 33 to form a sliding connection. Cylinders 35 are fixed on both sides of the moving block 33. The cylinders 35 slide in the card slots of a lifting plate 36 that is slidably connected to the inner wall of the water tank 1 up and down. The card slots form a trough body with two heights through an inclined path. A lifting box 37 is fixedly installed on the top of the lifting plate 36. The lifting box 37 is located below the conveyor belt 23. An air inlet pipe 13 is installed on one side of the water tank 1 away from the lifting box 37. One cylinder 35 passes through the opening on the side of the water tank 1 and is connected to an outer shaft 21 at one place with a driving part 4. The driving part 4 is used to drive the outer shaft 21 to rotate when the lifting box 37 is lifted.

[0038] As described above, through the design of the oil absorption part and the water lifting part, the exhaust gas enters the wet curtain chamber 11 through the air inlet pipe 13, and the clean water in the water tank 1 is transported to the wet curtain in the wet curtain chamber 11 through the water pump 12 (a filter is installed at the water inlet), and the wet curtain in the wet curtain chamber 11 adsorbs the paint particles on the exhaust gas, and the water can slowly flow back to the water tank 1, and the oil in the water will gradually float on the water surface. This is the existing conventional work flow, and then the oil absorbing paper roll 26 is pulled down through the main pressure cylinder 27 to fit on the rubber pad 25, and extends to the inside of the water tank 1, located above the lifting box 37, and glue is applied to the bottom of this part of the oil absorbing paper roll 26 in advance so that it can be adsorbed on the rubber pad 25, and it can be flattened and fitted through the main pressure cylinder 27, and then the motor 31 is started to drive the screw 32 to rotate, and under the limit of the cross bar 34, the moving block 33 is displaced, so that the cylinder 35 slides and displaces in the slot of the lifting plate 36, and when it passes through the ramp, it will move to a lower point. Each time the outer shaft 21 rotates to make the conveyor belt 23 operate, the oil absorbing paper roll 26 can be unwound and fitted with the conveyor belt 23. Note that the three sides of the lifting box 37 are in contact with the inner wall of the water tank 1.

[0039] The driving part 4 includes an inner rod 41 fixedly docked with the cylinder 35 extending out of the water tank 1, and the inner rod 41 slides in an opening on one side of the barrel rod 42. The driving rod 43 is rotatably installed on the top of the barrel rod 42, and the driving rod 43 is rotatably installed on the bottom of the lifting rod 44. The lifting rod 44 passes through a support plate on the side of the bracket for installing the outer shaft 21, and two guide rods 46 are also fixed on the top of the support plate. A rack plate 45 is docked on the top of the lifting rod 44, and the guide rod 46 passes through the rack plate 45 to form a sliding connection. The rack plate 45 is meshed with a gear 47, and the gear 47 is installed on the side of a driving circular plate 48, which drives the circular plate 48 to dock with the rotating shaft of the outer shaft 21 through a connecting shaft. It should be noted that the inner rod 41 cannot be detached from the inside of the barrel rod 42, that is, there is a circular plate at the inner end of the inner rod 41, which is a piston-like design.

[0040] As described above, through the driving part 4, when the cylinder 35 moves in the high-position card slot of the lifting plate 36, the inner rod 41 is driven by the extending end of the cylinder 35 to slide into the inner part of the cylinder rod 42. When it slides to the innermost end and can push the cylinder rod 42 to displace, the cylinder 35 moves to the low-position horizontal card slot of the lifting plate 36 through the inclined slot. At this time, the paint on the water surface contacts the corresponding absorbent paper roll 26. Then, the moving block 33 continues to move. The displacement of the cylinder rod 42 causes the driving rod 43 to rotate and push the lifting rod 44. The lifting rod 44 pushes the rack plate 45. The rack plate 45 slides upward under the limitation of the guiding rod 46, causing the gear 47 to rotate, driving the circular plate 48 to drive an outer shaft 21 to rotate. Through the conveyor belt 23 and the other outer shafts 21 and inner shafts 22, they can rotate together to operate, bringing the new absorbent paper roll 26 to the position above the lifting box 37. Until the cylinder 35 moves to the end of the low-position card slot of the lifting plate 36, after the oil absorption work is completed, it can be reset.

[0041] The driving circular plate 48 includes an inner circular plate 481 and an outer circular plate 484. The inner circular plate 481 is rotatably installed in the circular opening at the side end of the outer circular plate 484. There are openings on both sides of the inner circular plate 481. The abutting plates 482 are rotatably installed in the openings. The abutting plates 482 and the inner circular plate 481 openings are connected with springs 483. The outer circular plate 484 is butt-connected to the rotating shaft of an outer shaft 21 through a connecting shaft. The abutting plates 482 can be fitted into the fitting grooves annularly distributed on the inner wall of the circular opening of the outer circular plate 484, and at this time, the abutting plates 482 rotate to the maximum angle in the direction away from the inner circular plate 481.

[0042] During reset, due to the rotational resistance of the outer shaft 21 and the inner shaft 22, the inner rod 41 slowly extends from the cylinder rod 42 until the end of the inner rod 41 abuts against the inner wall of the opening of the cylinder rod 42. At this time, the inner rod 41 drives the cylinder rod 42 to move back, which can make the rack plate 45 move down to reset. The cylinder 35 moves to the high-position horizontal card slot of the lifting plate 36 through the inclined slot, causing the lifting box 37 to drop below the water level to re-ship the paint. At this time, the inner circular plate 481 is driven by the gear 47 to rotate. At this time, the abutting plates 482 on the inner circular plate 481 rotate along the inner fitting grooves of the outer circular plate 484, and will continue to be compressed into the notch of the inner circular plate 481 and then ejected by the spring 483, and finally get stuck in an inner fitting groove of the outer circular plate 484 (that is, unable to overcome the rotational resistance of the outer shaft 21 and the inner shaft 22). When the rack plate 45 moves upward, since the abutting plates 482 rotate against the inner fitting grooves of the outer circular plate 484, and the abutting plates 482 rotate to the maximum angle in the direction away from the inner circular plate 481, at this time, they can abut against the inner fitting grooves of the outer circular plate 484 and push the outer circular plate 484 to rotate. The outer circular plate 484 can drive an outer shaft 21 to rotate. In this way, when the lifting box 37 drops and the cylinder 35 moves back, that is, when the rack plate 45 moves down, the conveyor belt 23 does not operate, ensuring the stability of the operation.

[0043] The inner bottom surface and three side surfaces of the water tank 1 are provided with L-shaped plates 39. The L-shaped plates 39 cover the lifting plate 36 inside. The top of the lifting plate 36 is butted against the bottom of the lifting box 37 through four vertical rods 38. The vertical rods 38 are hermetically inserted and slidably connected with the L-shaped plates 39. A cylinder 35 passes through the side opening of the water tank 1 and is located inside the L-shaped plate 39.

[0044] The L-shaped plates 39 cover the lead screw 32, the moving block 33, and the cross bar 34. This space is free of water (because the vertical rods 38 are hermetically inserted and slidably connected with the L-shaped plates 39), and the cylinder 35 passing through the side opening of the water tank 1 also does not let water out, thus playing a good protective role.

[0045] A paper scraping part 5 is installed on one side of the water tank 1, which includes a collection box 51 and a scraping plate 52. The collection box 51 is attached to the side wall of the water tank 1. The scraping plate 52 is butted against the top of the collection box 51 through a connecting rod, and the other end of the scraping plate 52 is attached to the vertically arranged rubber pad 25, that is, this part of the rubber pad 25 is located between two vertically aligned outer shafts 21.

[0046] Through the design of the paper scraping part, the oil-absorbing oil-absorbing paper is removed from an opening of the water tank 1, and this part of the conveyor belt 23 will be scraped off and fall into the collection box 51 for collection when passing through the scraping plate 52.

[0047] A cleaning part 6 is installed on the top of the water tank 1. The cleaning part 6 includes a degumming box 61 fixed on the top of the water tank 1. The degumming box 61 is provided with an opening through which the conveyor belt 23 passes. An electric heating tube 62 is installed inside the degumming box 61, and a cleaning brush 63 is rotatably installed. An inclined baffle 64 is fixed on the inner wall of the degumming box 61. The baffle 64 is attached to the conveyor belt 23 and the rubber pad 25. A drain pipe 65 penetrates through one side of the degumming box 61. The air inlet end of the drain pipe 65 penetrates into the inside of the water tank 1. The rotating shaft of the cleaning brush 63 is butted against a pulley 66 rotatably installed on the side of the degumming box 61. The pulley 66 is butted against the rotating shaft of the outer circular plate 484 and the outer shaft 21 through a belt 67. The rotating shaft and two circular plates are used to limit the wound belt 67.

[0048] Through the design of the cleaning part 6, there will be residual glue on the scraped part. At this time, this part of the conveyor belt 23 enters the degumming box 61, and the glue is dried by the electric heating tube 62. At the same time, the air flow inside the water tank 1 introduced by the air inlet pipe 13 is discharged through the drainage pipe 65, so that the hot air inside the degumming box 61 is in a flowing state. When the conveyor belt 23 is not operating (that is, when the cylinder 35 is not operating in the low-position card slot of the lifting plate 36), this part of the glue is quickly dried. When the conveyor belt 23 operates, the rotation of the outer circular plate 484 will drive the cleaning brush 63 to rotate through the belt pulley 66 and the belt 67, and brush off the dried glue to prevent it from sticking to the conveyor belt 23. Immediately, these glue particles are intercepted by the baffle 64 and fall from the conveyor belt 23, and fall to the bottom end inside the degumming box 61, so as to ensure that subsequently, the absorbent paper on the absorbent paper roll 26 can be closely attached to the conveyor belt 23, improving the stability of the absorbent paper for absorbing paint.

[0049] The gluing part 7 is installed on one side of the water tank 1. The gluing part 7 includes a constant-temperature glue storage box 71 fixed on the side wall of the water tank 1. A glue pumping pump 72 is arranged at the top of the constant-temperature glue storage box 71. The output end of the glue pumping pump 72 is butt-connected to the glue spraying pipe 73 installed between the connecting plates. A row of nozzles is arranged at the top of the glue spraying pipe 73, which can be designed as wide-angle nozzles, mainly for spraying glue on the absorbent paper roll 26 close to the direction of the main pressing cylinder 27, below the absorbent paper being transported. The main pressing cylinder 27 is installed between these connecting plates, and a row of auxiliary pressing cylinders 28 is rotatably connected between the side end support plates of the bracket with two outer shafts 21 installed at one end.

[0050] As described above, the glue pumping pump 72 in the gluing part 7 is started synchronously when the conveyor belt 23 operates. Cooperating with the pressing of the main pressing cylinder 27, the absorbent paper on the absorbent paper roll 26 can be closely attached to the conveyor belt 23. Synchronously, the auxiliary pressing cylinder 28 can further improve the pressing effect. It should be noted that initially, the absorbent paper roll 26 is pulled down through the main pressing cylinder 27 and attached to the rubber pad 25, and extends into the water tank 1, and also passes through the auxiliary pressing cylinder 28.

[0051] Both ends of the rubber pad 25 are designed in an arc shape. Therefore, both sides of the main pressing cylinder 27 are also designed in an arc shape. At the same time, both sides of the absorbent paper attached to the rubber pad 25 are also in an arc shape, but do not contact the conveyor belt 23. The baffle 64 is provided with a bayonet corresponding to the rubber pad 25.

[0052] Finally, as shown in Figure 8 , the appearance design of the rubber pad 25 is just right. The liquid level inside the lifting box 37 is as shown by the mark a. After the absorbent paper is attached to the rubber pad 25, the two sides are designed in an arc shape, so that the water will not contact the conveyor belt 23 (a small amount has no impact). At the same time, the arc shape on both sides of the main pressing cylinder 27 can better attach the absorbent paper to the rubber pad 25, which is very practical.

[0053] Working principle: The paint spraying waste gas enters the wet curtain chamber 11 through the air inlet pipe 13. The water pump 12 transports the clear water in the water tank 1 to the wet curtain in the wet curtain chamber 11. The wet curtain adsorbs and filters the paint particles in the waste gas. The filtered water gradually flows back to the water tank 1, and the oil stains in the water float on the water surface. The absorbent paper roll 26 is laid inside the water tank 1 through the conveyor belt 23. After the bottom of the absorbent paper is glued, it is flattened and attached to the rubber pad 25 of the conveyor belt 23 by the main pressing cylinder 27 and the auxiliary pressing cylinder 28. The motor 31 is started, the lead screw 32 drives the moving block 33 to move, the cylinder 35 slides in the card slot of the lifting plate 36, and the lifting box 37 is pushed to rise. The lifting box 37 takes out the oil stains on the water surface and contacts the absorbent paper for adsorption. Then, the driving part 4 drives the outer shaft 21 to rotate through the rack plate 45 and the gear 47. The conveyor belt 23 pulls the new absorbent paper roll 26 above the lifting box 37 to complete the replacement of the absorbent paper. When the cylinder 35 slides in the card slot of the lifting plate 36, the rack plate 45 is driven to move up and down through the inner rod 41, the cylinder rod 42, the driving rod 43 and the lifting rod 44. The gear 47 drives the circular plate 48 to rotate. The driving circular plate 48 adopts a ratchet structure design to ensure that the outer shaft 21 rotates when the rack plate 45 rises and the outer shaft 21 does not rotate when the rack plate 45 descends, ensuring the one-way operation of the conveyor belt 23. The absorbent paper that has completed oil absorption is removed through the conveyor belt 23. The scraper 52 scrapes off the absorbent paper and drops it into the collection box 51 for recycling. The conveyor belt 23 enters the degumming box 61. The electric heating tube 62 dries the residual glue, and the cleaning brush 63 brushes off the dried glue. The baffle 64 intercepts the glue particles to ensure the cleanliness of the conveyor belt 23.
