Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of waste gas collection and treatment equipment, and in particular to a spraying waste gas collection and treatment equipment with adaptive air volume adjustment. Background Technology
[0002] Spraying is a coating method that uses a spray gun or disc atomizer to atomize and disperse paint into uniform and fine droplets using pressure or centrifugal force, and then applies them to the surface of the object to be coated. This gives the workpiece a coating with physical and chemical properties such as wear resistance, corrosion resistance, heat insulation, conductivity, insulation, sealing, lubrication, and other special mechanical properties. During spraying, in order to avoid air pollution caused by paint droplets, the spraying exhaust gas is collected and purified.
[0003] However, in the existing technology, when treating spray painting exhaust gas, the exhaust gas is drawn into the collection and purification box by a fan with adjustable air volume, and then directly filtered by the multi-layer filter plate in the purification box. However, since the spray painting exhaust gas contains a small amount of paint mist droplets, after being filtered, they adhere to the filter plate. After drying, they easily form a coating on the filter plate, causing the filter plate to become clogged and affecting the subsequent treatment effect of the treatment equipment. Utility Model Content
[0004] The purpose of this invention is to solve the problem that paint droplets easily clog the filter material during purification in existing adaptive airflow-adjustable spraying exhaust gas collection and treatment equipment, and to propose an adaptive airflow-adjustable spraying exhaust gas collection and treatment equipment.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: It includes a purification box, an air inlet, and an air outlet. A maintenance cover is fixed to the top of the purification box with bolts. An air inlet and an air outlet are respectively opened at both ends of the purification box. A fan is installed inside the purification box inside the air inlet, with the air outlet facing outwards. A discharge side box and a loading side box are respectively fixed to the two sides of the purification box near the air inlet. A purification plate is inserted inside the purification box between the discharge side box and the air outlet. The end of the purification plate extending to the outside of the purification box is fixed to the purification box with bolts. A winding roller is rotatably sleeved inside both the discharge side box and the loading side box. Filter cotton is wound around the winding roller inside the loading side box. The inner end of the filter cotton is fixed to the winding roller of the loading side box, and the end of the filter cotton extending to the outside of the loading side box is fixed to the winding roller inside the discharge side box.
[0006] Preferably, protective mesh plates are fitted and fixed inside the purification box on the inner side of the air inlet and air outlet. Both purification plates are set as horizontally placed T-shaped plates, and the two purification plates extend into the purification box at one end as a glass fiber filter plate and an activated carbon filter plate, respectively.
[0007] Preferably, the top surfaces of both the unloading side box and the loading side box are fixedly covered with sealing covers, a servo motor is provided at the bottom of the unloading side box, and a rotating disk is rotatably connected to the bottom surface of both the unloading side box and the loading side box. The output end of the servo motor passes through the bottom of the unloading side box and is fixed to the bottom surface of the rotating disk. A rectangular rotating rod is fixed to the top surface of both rotating disks, and both winding rollers are sleeved on the rectangular rotating rod.
[0008] Preferably, both sealing covers are fixed to the unloading side box and the loading side box respectively by bolts. Each sealing cover has another rotating disk rotatably connected to its bottom surface. Each of the other rotating disks has a rectangular groove at the center of its bottom that cooperates with the rectangular rotating rod.
[0009] Preferably, both take-up rollers have rectangular through holes that cooperate with the rectangular rotating rod, and the height between the upper and lower rotating disks is equal to the height of the take-up rollers.
[0010] Preferably, a pressure roller is slidably arranged inside the feeding side box outside the winding roller, a protective sleeve is fixed outside the feeding side box, a fixing plate is fixed inside the protective sleeve, and a plurality of connecting slide rods are equidistantly slidably sleeved inside the fixing plate. The end of each connecting slide rod near the purification box is fixed to the outer surface of the pressure roller, and a spring is sleeved on each connecting slide rod outside the pressure roller. Both ends of the spring are fixed to the pressure roller and the fixing plate, respectively.
[0011] Preferably, the height of the pressure roller is equidistant from the height of the winding roller, and slots for the filter cotton are provided on both sides of the purification box. Baffles are fixed on the inner walls of the purification box on both the upper and lower ends of the filter cotton.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0013] 1. In this utility model, by continuously moving and replacing the filter cotton, when filtering the spraying exhaust gas, the paint mist droplets in the exhaust gas can be filtered and collected first. The collected filter cotton is rolled up inside the unloading side box, and the exhaust gas can continue to flow and be filtered by the purification plate. This solves the problem that paint mist droplets easily cause filter material blockage during purification in the existing spraying exhaust gas collection and treatment equipment with adaptive air volume adjustment, and improves the treatment effect of the purification device.
[0014] 2. In this utility model, the movable pressure roller ensures that the filter cotton is in a tense state during unwinding and rewinding, preventing gaps between the filter cotton edges and the inner wall of the purification chamber caused by the looseness of the filter cotton. This prevents unfiltered exhaust gas from passing through the filter cotton and further ensures the purification effect of the treatment equipment. Attached Figure Description

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. Example
[0022] like Figure 1-4As shown, this utility model provides an adaptive airflow-adjustable spraying exhaust gas collection and treatment device, including a purification box 1, an air inlet 2, and an air outlet 3. A maintenance cover 8 is bolted to the top of the purification box 1. The purification box 1 has an air inlet 2 and an air outlet 3 at both ends. Protective mesh plates 4 are fitted and fixed inside the purification box 1 on the inner sides of both the air inlet 2 and the air outlet 3. A fan is installed inside the purification box 1 inside the air inlet 2, with the air outlet facing the air outlet 3. A discharge side box 5 and a loading side box 6 are fixed to the two sides of the purification box 1 near the air inlet 2, respectively. A purification plate 7 is inserted inside the purification box 1 between the discharge side box 5 and the air outlet 3, extending to the outside of the purification box 1. One end is fixed to the purification box 1 by bolts, which facilitates the replacement of the purification plate 7. Both purification plates 7 are set as horizontally placed T-shaped. The two purification plates 7 extend into the purification box 1 at one end, which are glass fiber filter plates and activated carbon filter plates, respectively. The feeding side box 5 and the feeding side box 6 are both rotatably sleeved with winding rollers 13. Filter cotton is wound on the winding roller 13 inside the feeding side box 6. The inner end of the filter cotton is fixed on the winding roller 13 of the feeding side box 6. The end of the filter cotton extending to the outside of the feeding side box 6 is fixed on the winding roller 13 inside the feeding side box 5. The purification box 1 has slots on both sides to match the filter cotton. Baffles are fixed on the inner walls of the purification box 1 on both the upper and lower ends of the filter cotton.
[0023] The specific setup and function of this embodiment are described below: Both the top surfaces of the unloading side box 5 and the loading side box 6 are fixedly covered with sealing covers 10. The two sealing covers 10 are respectively fixed to the unloading side box 5 and the loading side box 6 by bolts. Each sealing cover 10 has a rotating disk 11 rotatably sleeved on its bottom surface. Each of the two rotating disks 11 has a rectangular groove at its bottom center that mates with a rectangular rotating rod 12, allowing the upper and lower rotating disks 11 to rotate synchronously under the drive of the rectangular rotating rod 12. A servo motor 9 is installed at the bottom of the unloading side box 5. The bottom surfaces of both the unloading side box 5 and the loading side box 6 are rotatably sleeved... There is a rotating disk 11, and the output end of the servo motor 9 passes through the bottom of the unloading side box 5 and is fixed to the bottom surface of the rotating disk 11. A rectangular rotating rod 12 is fixed on the top surface of both rotating disks 11, and two take-up rollers 13 are sleeved on the rectangular rotating rods 12. The inside of each of the two take-up rollers 13 is provided with a rectangular through hole that cooperates with the rectangular rotating rod 12, so that the rectangular rotating rod 12 can drive the take-up rollers 13 to rotate. The height between the upper and lower rotating disks 11 is equal to the height of the take-up rollers 13. Through the detachable design between the take-up rollers 13 and the rectangular rotating rods 12, it is convenient to replace the filter cotton during use, ensuring the convenience of maintenance of the processing device. Example
[0024] like Figure 1-4As shown, a pressure roller 15 is slidably installed inside the feeding side box 6 outside the take-up roller 13. A protective sleeve box 14 is fixed outside the feeding side box 6. A fixing plate 16 is fixed inside the protective sleeve box 14. Several connecting slide rods 17 are equidistantly slidably sleeved inside the fixing plate 16. The end of the connecting slide rod 17 near the purification box 1 is fixed to the outer surface of the pressure roller 15. The height of the pressure roller 15 is equidistant from the height of the take-up roller 13. Springs 18 are sleeved on the connecting slide rods 17 outside the pressure roller 15. Both ends of the springs 18 are fixed to the pressure roller 15 and the fixing plate 16, respectively.
[0025] The overall effect of this embodiment is that when the winding roller 13 inside the feeding side box 6 is unwinding, the pressure roller 15 can abut against the outermost layer of filter cotton, and the protective sleeve 14 that cooperates with the unloading side box 5 can ensure that the filter cotton is in a tense state when it is unwinding, so that the exhaust gas entering the purification box 1 can be treated by the filter cotton first.
[0026] The operating method and working principle of this device are as follows: When it is necessary to collect and purify the spray painting exhaust gas, turn on the fan inside the purification box 1 to draw the spray painting exhaust gas into the purification box 1 through the air inlet 2. The exhaust gas entering the purification box 1 is first filtered by filter cotton to remove paint droplets from the exhaust gas. Then, it is filtered sequentially by two purification plates 7 and discharged from the air outlet 3. While the filter cotton is filtering, the servo motor 9 drives the winding roller 13 at the bottom of the unloading side box 5 to rotate, so that the winding roller 13 rotates to wind up the filter cotton that has absorbed paint droplets. The winding roller 13 inside the loading side box 6 rotates synchronously to unwind. At this time, the pressure roller 15 always abuts against the outermost layer of the filter cotton roll. Unroll the filter cotton roll. The pressure roller 15, pushed by the spring 18, abuts against the outermost layer of the filter cotton roll. After the filter cotton is used up, tighten the bolts to release the sealing cover 10 from the feeding side box 5 and the feeding side box 6. Remove the sealing cover 10, open the feeding side box 5 and the feeding side box 6, insert the take-up roller 13 with the new filter cotton roll into the rectangular rotating rod 12 inside the feeding side box 6, pull the outer end of the filter cotton so that the filter cotton passes through the purification box 1 and enters the feeding side box 5, and is bonded and fixed to the take-up roller 13 inside the feeding side box 5. When the filter cotton passes through the purification box 1, the upper and lower ends pass through the baffles on both sides. Then, fix the sealing cover 10 to the top of the feeding side box 5 and the feeding side box 6 respectively.
[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
