Description
Technical Field
[0001] This invention relates to the field of automotive body painting exhaust gas treatment technology, specifically a regenerative high-temperature oxidation treatment device for automotive body painting exhaust gas. Background Technology
[0002] Painting is a crucial part of vehicle pre-treatment. With increasingly stringent environmental regulations in recent years, the treatment of exhaust gases in painting workshops has received more and more attention. At the same time, painting exhaust gases are extremely harmful, so it is essential to install exhaust gas treatment equipment in painting workshops.
[0003] Painting exhaust includes volatile compounds, paint mist particles, and other harmful heavy metals. Since manual labor cannot be completely avoided in the painting process, when workers use handheld sprayers, their movement around the vehicle body causes some airflow disturbance in the painting workshop. As soon as the handheld sprayer sprays paint, paint far from the center line of the nozzle will overflow in an outward V-shape under the interference of gravity and turbulent airflow. Once the worker moves around, a large amount of overflowing paint mist will adhere to the worker's clothing, and the diffused paint mist will also affect the vision of workers wearing safety goggles.
[0004] In view of this, a heat storage high-temperature oxidation treatment device for vehicle body painting exhaust gas was designed to solve the above problems. Summary of the Invention

[0008] In a preferred embodiment, the present invention may be further configured such that: the waste gas treatment mechanism further includes a first row of waste frames installed at the bottom of the outer end of the heat-insulating outer tube, a second row of waste frames installed at the bottom of the inner end of the heat-insulating outer tube, a first storage bin installed inside the first row of waste frames, and a second storage bin installed inside the second row of waste frames; The top of both the first and second rows of waste frames is provided with a funnel-shaped cavity. Both the first and second storage compartments are made of heat-insulating material, and the inner walls of the first and second storage compartments are provided with ceramic layers.
[0009] In a preferred embodiment, the present invention may be further configured as follows: the gun body clamping mechanism includes two rings clamping the barrel of the handheld spray gun, two locking bolts disposed within the two rings, a base installed at the bottom of the two rings, an arc-shaped frame installed at the bottom of the base, a base installed outside the base, a motor installed inside the base, and an energy storage component installed outside the base. The energy storage component is connected to the motor via wires.
[0010] In a preferred embodiment, the present invention may be further configured such that the gun body clamping mechanism further includes a first drive wheel mounted on the internal transmission shaft of the motor; The exhaust gas treatment mechanism also includes a take-up reel and a second drive wheel installed at the bottom of the inner shaft of the take-up reel; A transmission belt is connected to the first drive wheel and the second drive wheel.
[0011] In a preferred embodiment, the present invention can be further configured such that: two symmetrically distributed clamping plates are fixedly installed on the outer side of the end post, and the end post has an L-shaped wire hole inside; The other end of the cable is adapted to pass through the outside of the wire hole and is wound onto the take-up reel.
[0012] In a preferred embodiment, the present invention may be further configured such that: the thermal oxidation mechanism further includes a preload bolt disposed inside the plug, a heat insulation plug disposed in a screw hole inside the plug, and a tension spring connecting the preload bolt and the plug; The inner end of the heat-insulating plug is adapted to penetrate into the hole at the end face of the preloaded bolt.
[0013] In a preferred embodiment, the present invention can be further configured such that: the inner wall of the outer end of the heating inner tube is provided with a plurality of uniformly distributed slots; The end face of the plug extending into the inner cavity of the heating inner tube is provided with multiple evenly distributed pads, and the inner side of the pads is provided with an inclined surface that fits into the preload bolt.

[0016] By adopting the above technical solution, the beneficial effects achieved by the present invention are as follows: 1. This invention provides a gun body clamping mechanism outside the barrel of a handheld spray gun. When the external air pipe is connected to the exhaust pipe and air is continuously discharged, the paint mist ejected from the handheld spray gun and overflowing will be actively absorbed. The absorbed paint mist will eventually pass through the high-temperature gap between the heat-insulating outer tube and the heating inner tube, thereby performing high-temperature oxidation and decomposition treatment on the absorbed paint mist. The decomposed gas will be discharged, while the decomposed and settled dirt will remain on the heat-insulating outer tube and the heating inner tube, thus preventing paint mist from overflowing and adhering to workers' clothes, while ensuring the cleanliness of the painting workshop.
[0017] 2. This invention decomposes the paint mist between the heat-insulating outer tube and the heating inner tube at high temperature. The dirt remaining on the outer wall of the heating inner tube and the inner wall of the heat-insulating outer tube is scraped horizontally by a regularly extending annular scraper. The scraped dirt that falls down along the annular scraper is transferred to the first and second storage bins through the first and second waste frames, respectively. This continuous cleaning of the heating inner tube and the heat-insulating outer tube avoids the problem of reduced paint mist decomposition efficiency.
[0018] 3. This invention sets two sets of exhaust gas treatment mechanisms on both sides of the bottom of the spray gun. As soon as the spray gun sprays paint, the two sets of exhaust gas treatment mechanisms will absorb the sprayed and overflowing paint mist downwards. The overflowing paint mist will be continuously discharged through a U-shaped return path, thereby avoiding the problem of the overflowing paint mist spreading due to airflow and gravity caused by workers walking around, thus ensuring the cleanliness of the upper body space of workers.

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.
[0022] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the invention.
[0023] The following describes, with reference to the accompanying drawings, some embodiments of a regenerative high-temperature oxidation treatment device for vehicle body painting exhaust gas.
[0024] Example 1: Combination Figures 1 to 10 As shown, the present invention provides a regenerative high-temperature oxidation treatment device for vehicle body painting exhaust gas, including a handheld spray gun 100, a gun body clamping mechanism 200 disposed on the handheld spray gun 100, two sets of exhaust gas treatment mechanisms 300 disposed within the gun body clamping mechanism 200, and a thermal oxidation mechanism 400 disposed within the exhaust gas treatment mechanism 300. The gun body clamping mechanism 200 is used to provide a clamping platform for the two sets of exhaust gas treatment mechanisms 300. The two sets of exhaust gas treatment mechanisms 300 are used to actively absorb the paint mist overflowing after spraying from the handheld spray gun 100. The thermal oxidation mechanism 400, in conjunction with the high-temperature environment generated by the exhaust gas treatment mechanism 300, is used to oxidize and decompose the absorbed paint mist. The exhaust gas treatment mechanism 300 includes an end post 310, a wire hole 3101 opened inside the end post 310, a heat-insulating outer tube 370 disposed at the inner end of the end post 310, two insulating shells 320 installed inside the end post 310, and a wire clamping sleeve 330 installed inside the two insulating shells 320. An exhaust pipe 390 is installed inside the heat-insulating outer tube 370. The thermal oxidation mechanism 400 includes a heating inner tube 410 installed at the inner end of the end post 310 and extending into the inner cavity of the heat-insulating outer tube 370, a coil 420 disposed inside the heating inner tube 410, a plug 480 installed at the outer end of the heating inner tube 410, an annular scraper 430 movably installed outside the heating inner tube 410, a cable 440 connected to the inner side of the annular scraper 430, a sheath 450 installed on the outer side of the annular scraper 430, a limiting rod 470 installed in the inner hole of the plug 480, a high-temperature resistant tension spring 460 disposed outside the limiting rod 470, a preload bolt 4801 disposed inside the plug 480, a heat-insulating plug 4803 disposed in the screw hole inside the plug 480, and a sub-tension spring 4802 connected between the preload bolt 4801 and the plug 480. The inner end of the heat-insulating plug 4803 is fitted into the hole on the end face of the preload bolt 4801; One end of the high-temperature resistant tension spring 460 is installed on the limiting rod 470, and the other end of the high-temperature resistant tension spring 460 is adapted to penetrate into the sheath 450 and fixed on the annular scraper 430; The annular scraper 430 is used to regularly clean the dirt that has been decomposed and settled on the outer wall of the heating inner tube 410 and the inner wall of the heat insulation outer tube 370. A filter screen 380 is installed in the annular groove at one end of the heat-insulating outer tube 370 near the plug 480 to guide the exhaust gas in. Two insulating housings 320 are used to provide thermal insulation protection for the conductors inside the coil 420; The wire clamp 330 is used to provide breakage protection for the conductors inside the coil 420; The inner wall of the outer end of the heating inner tube 410 is provided with multiple evenly distributed slots; The end face of the plug 480 extending into the inner cavity of the heating inner tube 410 is provided with multiple evenly distributed pads, and the inner side of the pads is provided with an inclined surface that fits against the preload bolt 4801. The cable 440 is coated with a heat-insulating coating on the outside, and the end face of the annular scraper 430 that is attached to the inner wall of the heat-insulating outer tube 370 gradually narrows. The beveled ends of the annular scraper 430 are used to guide dirt. When a worker holds a handheld spray gun 100 and approaches the irregular part of the car body, the paint will be sprayed directly onto the irregular part of the car body the moment it is sprayed from the inner end of the handheld spray gun 100. The paint mist that is far from the center line of the inner end of the handheld spray gun 100 will overflow. As the external air pipe cooperates with the exhaust pipe 390 to exhaust air to the heated inner pipe 410 and the heat-insulating outer pipe 370, the overflowing paint mist that permeates between the worker and the car body will be input from the filter screen 380. As the coil 420 is energized and continues to release heat, the high temperature will radiate into the gap between the heating inner tube 410 and the heat insulation outer tube 370. When the paint mist is continuously drawn in, the high temperature environment can oxidize and decompose the paint mist. The decomposed gas will be discharged from the exhaust pipe 390, and the remaining dirt will adhere to the outer wall of the heating inner tube 410 and the inner wall of the heat insulation outer tube 370. When the annular scraper 430 is pulled by the cable 440 and the high-temperature spring 460 and moves laterally in a precise and regular manner along the gap between the heating inner tube 410 and the heat-insulating outer tube 370, the settled dirt can be continuously and efficiently cleaned. The scraped dirt will fall down along the inclined surfaces at both ends of the annular scraper 430, and the finally fallen dirt will be stored in the first storage bin 3702 and the second storage bin 3704.
[0025] Example 2: Combination Figures 4 to 6 As shown, based on Embodiment 1, the gun body clamping mechanism 200 includes two rings 210 clamping the barrel of the handheld spray gun 100, two locking bolts 230 disposed in the two rings 210, a base 220 installed at the bottom of the two rings 210, an arc frame 240 installed at the bottom of the base 220, a base 250 installed outside the base 220, a motor 260 installed inside the base 250, a first drive wheel 270 installed on the transmission shaft inside the motor 260, and an energy storage component 280 installed outside the base 250. The energy storage component 280 is connected to the motor 260 via wires; The exhaust gas treatment mechanism 300 also includes a take-up reel 350 and a second drive wheel 360 installed at the bottom of the inner shaft of the take-up reel 350; A transmission belt 290 is connected to the first drive wheel 270 and the second drive wheel 360.
[0026] Preferably, the inner walls of both the ring 210 and the base 220 are provided with an anti-slip layer to increase frictional resistance, and the base 220 is composed of an arc-shaped support plate and a column; The base 250 is welded together from two T-shaped legs and a chassis; Adjust the position of the two rings 210 on the barrel of the handheld spray gun 100 according to the amount of paint mist sprayed from the inner end of the handheld spray gun 100, until the two filters 380 are misaligned with the nozzle of the handheld spray gun 100. As the handheld spray gun 100 continues to spray paint, the short-distance and large-area overflowing paint mist will be quickly sucked in by the two adjusted filters 380, thereby avoiding the problem of incomplete absorption of paint mist outside the center line of the nozzle inside the handheld spray gun 100.
[0027] Example 3: Combination Figures 5 to 10As shown, based on Embodiment 1, two symmetrically distributed clamping plates 340 are fixedly installed on the outer side of the end post 310, and an L-shaped wire hole 3101 is opened inside the end post 310. The bottom of the end post 310 is provided with a groove, and the groove at the bottom of the end post 310 provides a limit protection for the rotation of the transmission belt 290. The other end of the cable 440 is adapted to pass through the outside of the wire hole 3101 and is wound around the take-up wheel 350.
[0028] Preferably, the two winding wheels 350 are fixed to the end post 310 by welding, and the outer wall of the inner end of the end post 310 is provided with evenly distributed assembly grooves. The inner end of the heating inner tube 410 is provided with a plurality of evenly distributed studs, and the studs are adapted to penetrate into the assembly grooves. Nuts are provided on the studs to press against the inner wall of the assembly grooves.
[0029] The first row of waste frames 3701 is installed at the bottom of the outer end of the heat insulation outer tube 370, the second row of waste frames 3703 is installed at the bottom of the inner end of the heat insulation outer tube 370, the first storage bin 3702 is installed inside the first row of waste frames 3701, and the second storage bin 3704 is installed inside the second row of waste frames 3703. The top of the first row of waste frames 3701 and the second row of waste frames 3703 are both provided with funnel-shaped cavities. Both the first storage compartment 3702 and the second storage compartment 3704 are made of heat-insulating material, and the inner walls of the first storage compartment 3702 and the second storage compartment 3704 are provided with a ceramic layer.
[0030] Preferably, the inner wall of the heat-insulating outer tube 370 and the outer wall of the heating inner tube 410 are provided with a smooth coating. When the annular scraper 430 is regularly pulled and extends back and forth between the heating inner tube 410 and the heat-insulating outer tube 370, the settled dirt can be efficiently scraped off. After the dirt is removed, the heating inner tube 410 will work with the heat-insulating outer tube 370 to perform efficient oxidation and decomposition treatment on the inhaled paint mist. After the dirt inside the heating inner tube 410 and the heat insulation outer tube 370 is scraped off and stored, the first storage bin 3702 and the second storage bin 3704 can be replaced at a specified time period, thereby ensuring that the painting workshop is kept clean and avoiding interference from diffuse paint mist on the vision of workers wearing goggles.
[0031] The working principle and usage process of this invention: In the front painting process of a car, in addition to mechanical spraying, the irregular parts of the car body also need to be painted manually. However, during the manual painting operation, a large amount of paint mist will be generated between the car body and the worker. When the worker walks along the perimeter of the car body, airflow will be generated around the worker, which will cause diffuse paint mist to adhere to the worker's clothes. The device is used in conjunction with a handheld spray gun 100. When a worker holds the handheld spray gun 100 and sprays paint onto irregularly shaped parts of the car body, as the paint mist is continuously released, the paint mist sprayed by the handheld spray gun 100 at the moment of spraying will be directly sprayed onto the car body. The paint mist will overflow due to air resistance and the airflow around the worker. At the moment of overflow, the external air pipe is connected to the exhaust pipe 390. As the external air pipe exhausts air, the cavity formed by the exhaust pipe 390, the heat insulation outer pipe 370 and the heating inner pipe 410 will absorb the paint mist sprayed by the nozzle of the handheld spray gun 100 and the overflow. At this time, the paint mist sprayed along the center line of the nozzle of the handheld spray gun 100 will be sprayed directly onto the car body. As the spray distance increases, the overflowing paint mist will be actively absorbed by the return gas generated by the two filters 380 in an outward V-shape. At the same time, the coil 420 will release heat energy when energized until the entire inner tube 410 continuously releases high temperature. As the absorbed paint mist continues to pass through the outer surface of the inner tube 410, the paint mist can be oxidized and decomposed at high temperature. The decomposed residue will settle on the outer wall of the inner tube 410 and the inner wall of the heat insulation outer tube 370. The decomposed water and gas will continue to be output outward along the gap between the inner tube 410 and the heat insulation outer tube 370, and finally be discharged from the external gas pipe. As the amount of sediment on the outer wall of the heating inner tube 410 and the inner wall of the heat insulation outer tube 370 continues to increase, the motor 260 rotates regularly in both forward and reverse directions. When the first drive wheel 270 rotates forward, the first drive wheel 270 driven by the transmission shaft inside the motor 260 will drive two second drive wheels 360. The combined second drive wheels 360 and the winding wheel 350 will pull the cable 440. At this time, the annular scraper 430 will move laterally along the outer wall of the heating inner tube 410 and the inner wall of the heat insulation outer tube 370. The sediment scraped off by the annular scraper 430 will be transferred to the first storage bin 3702 and the second storage bin 3704 along the first waste frame 3701 and the second waste frame 3703 respectively. When the first drive wheel 270 reverses, the combined winding wheel 350 and the second drive wheel 360 will loosen the cable 440, and under the traction of the high temperature spring 460, the annular scraper 430 will quickly reset, and finally the annular scraper 430 will perform secondary cleaning of the outer wall of the heating inner tube 410 and the inner wall of the heat insulation outer tube 370. By setting two sets of thermal oxidation mechanisms 400 on both sides of the nozzle of the handheld spray gun 100 to extract overflow paint mist, the paint sprayed directly along the center line of the nozzle of the handheld spray gun 100 will accurately adhere to the irregular parts of the car body the moment the handheld spray gun 100 sprays paint, while the paint mist that overflows outside the center line of the nozzle of the handheld spray gun 100 will be actively absorbed. At this time, the worker's direction of movement can be prevented from being blocked by the diffused paint mist, and the adhesion and contamination of the diffused paint mist to the worker's clothes can be reduced.
[0032] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
