Technical Field

[0001] The present invention relates to the technical field of vehicle body painting waste gas treatment, and in particular to a thermal storage high-temperature oxidation treatment device for vehicle body painting waste gas. Background Art

[0002] The painting process is an important part of vehicle body processing. With the increasingly stringent environmental protection system in recent years, the exhaust gas treatment in the painting workshop has also received more and more attention. At the same time, the harmfulness of painting exhaust gas is extremely great, so it is extremely necessary to install exhaust gas treatment equipment in the painting workshop.

[0003] Painting exhaust includes volatile compounds, paint mist particles and other harmful heavy metal substances. Since manual labor cannot be completely avoided in the painting process, when workers use handheld spray paint devices, the workers' movement around the car body will cause a certain degree of turbulence in the air flow in the painting workshop. As the handheld spray paint device sprays the paint, the paint away from the center line of the nozzle will overflow in an outward-facing structure under the interference of gravity and turbulent airflow. Once the workers walk, a large amount of overflowed paint mist will adhere to the workers' clothes. At the same time, the diffuse paint mist will also affect the vision of workers wearing goggles.

[0004] In view of this, a body painting exhaust gas heat storage high-temperature oxidation treatment equipment was designed to solve the above problems. Summary of the Invention

[0021] To make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other without conflict.

[0022] It is to be understood that these descriptions are illustrative only and are not intended to limit the scope of the invention.

[0023] The following describes a thermal storage high-temperature oxidation treatment device for vehicle body painting exhaust gas provided by some embodiments of the present invention in conjunction with the accompanying drawings.

[0024] Example 1: Combine Figures 1 to 10 As shown, the present invention provides a thermal storage high-temperature oxidation treatment device for vehicle body painting exhaust gas, comprising a handheld spray gun 100, a gun body clamping mechanism 200 provided on the handheld spray gun 100, two sets of exhaust gas treatment mechanisms 300 provided in the gun body clamping mechanism 200, and a thermal oxidation mechanism 400 provided in 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 cooperates with the high temperature environment generated by the exhaust gas treatment mechanism 300 to oxidize and decompose the absorbed paint mist. The exhaust gas treatment mechanism 300 includes an end post 310, a wire hole 3101 defined within the end post 310, a heat-insulating outer tube 370 disposed at the inner end of the end post 310, two insulating housings 320 mounted on the inner side of the end post 310, and a wire clamp 330 mounted within the two insulating housings 320. An exhaust pipe 390 is mounted within 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 column 310 and extending through the inner cavity of the heat-insulating outer tube 370, a coil 420 disposed inside the heating inner tube 410, a plug 480 mounted on the outer end of the heating inner tube 410, an annular scraper 430 movably mounted on the outside of the heating inner tube 410, a cable 440 connected to the inside of the annular scraper 430, a sheath 450 mounted on the outside of the annular scraper 430, a limiting rod 470 installed in a hole inside the plug 480, a high-temperature resistant tension spring 460 disposed outside the limiting rod 470, a pre-stressing bolt 4801 disposed inside the plug 480, a heat-insulating plug 4803 disposed in a screw hole inside the plug 480, and a sub-tension spring 4802 connected between the pre-stressing bolt 4801 and the plug 480. The stud at the inner end of the heat-insulating plug 4803 is adapted to penetrate into the hole on the end face of the preload bolt 4801; One end of the high temperature resistant tension spring 460 is mounted on the limiting rod 470 , and the other end of the high temperature resistant tension spring 460 is adapted to penetrate the interior of the sheath 450 and fixed on the annular scraper 430 ; The annular scraper 430 is used to regularly clean the dirt that has decomposed and settled on the outer wall of the heating inner tube 410 and the inner wall of the insulation outer tube 370; A filter 380 is installed in the annular groove of the insulating outer tube 370 near the end of the plug 480 to guide the exhaust gas into the tube; The two insulating shells 320 are used to provide thermal insulation protection for the wires in the coil 420; The wire clamp 330 is used to provide anti-breaking protection for the wire inside the coil 420; The inner wall of the outer end of the inner heating tube 410 is provided with multiple evenly distributed grooves; The end surface of the plug 480 that passes through the inner cavity of the heating inner tube 410 is provided with a plurality of evenly distributed pads, and the inner side of the pads is provided with an inclined surface that fits the pre-load bolt 4801; The exterior of the cable 440 is coated with a heat-insulating coating, and the end surface of the annular scraper 430, which is attached to the inner wall of the heat-insulating outer tube 370, gradually narrows; The inclined surfaces at both ends of the annular scraper 430 are used to guide the dirt When a worker holds the handheld spray gun 100 and approaches the irregularly shaped part of the car body, the paint will be directly sprayed on the irregularly shaped part of the car body at the moment of spraying from the inner end of the handheld spray gun 100, while the paint mist away 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 from the heating inner pipe 410 and the insulation outer pipe 370, the paint mist that overflows and spreads between the worker and the car body will be input through the filter 380; As the coil 420 is energized and continuously releases heat, the high temperature radiates into the gap between the heating inner tube 410 and the insulating outer tube 370. As the paint mist is continuously absorbed, the high temperature environment oxidizes and decomposes the paint mist. The decomposed gas is discharged outward from the exhaust pipe 390, and the remaining dirt adheres to the outer wall of the heating inner tube 410 and the inner wall of the insulating outer tube 370. When the annular scraper 430 is pulled by the pull rope 440 and the high-temperature resistant tension spring 460 and moves horizontally along the gap between the heating inner tube 410 and the insulating outer tube 370 in a fine and regular manner, the settled dirt can be cleaned continuously and efficiently, and the scraped dirt will fall along the inclined surfaces at both ends of the annular scraper 430, and the fallen dirt will eventually be stored in the first storage bin 3702 and the second storage bin 3704.

[0025] Example 2: Combine Figures 4 to 6 As shown, based on Example 1, the gun body clamping mechanism 200 includes two ring buckles 210 clamped on the outside of the barrel of the handheld spray gun 100, two locking bolts 230 arranged in the two ring buckles 210, a base 220 installed at the bottom of the two ring buckles 210, an arc-shaped frame 240 installed at the bottom end of the base 220, a base 250 installed outside the base 220, a motor 260 installed inside the base 250, a first driving wheel 270 installed on the transmission shaft in the motor 260, and an energy storage assembly 280 installed outside the base 250; The energy storage assembly 280 is connected to the motor 260 via a wire; The exhaust gas treatment mechanism 300 further includes a reel 350 and a second driving wheel 360 mounted at the bottom of the shaft within the reel 350 ; The first driving wheel 270 and the second driving wheel 360 are connected to each other via a transmission belt 290 .

[0026] Preferably, the inner walls of the ring buckle 210 and the base 220 are both provided with an anti-slip layer to increase friction resistance, and the base 220 is composed of an arc-shaped support plate and a column; The base 250 is welded together by two T-shaped legs and a chassis; The positions of the two assembled ring buckles 210 on the barrel of the handheld spray gun 100 are adjusted according to the amount of paint mist sprayed from the inner end of the handheld spray gun 100, until a misalignment is formed between the two filters 380 and the nozzle of the handheld spray gun 100. As the handheld spray gun 100 continues to spray paint, the paint mist that overflows over a short distance and a large range will be quickly sucked in by the two adjusted filters 380, thereby avoiding the problem of incomplete absorption of the paint mist outside the center line of the nozzle of the handheld spray gun 100.

[0027] Example 3: Combine Figures 5 to 10As shown, based on Example 1, two symmetrically distributed clamping plates 340 are fixedly installed on the outer side of the end column 310, and an L-shaped wire hole 3101 is opened inside the end column 310; A groove is provided at the bottom of the end column 310 , and the groove at the bottom of the end column 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 winding wheel 350 .

[0028] Preferably, the two winding wheels 350 are fixed to the end column 310 by welding, and the outer wall of the inner end of the end column 310 is provided with evenly distributed assembly grooves, and the inner end of the heating inner tube 410 is provided with a plurality of evenly distributed studs, and the studs are adapted to pass through the assembly grooves, and nuts are provided on the studs to tighten the inner wall of the assembly groove.

[0029] A first row of waste frames 3701 installed at the bottom of the outer end of the insulated outer tube 370, a second row of waste frames 3703 installed at the bottom of the inner end of the insulated outer tube 370, a first storage bin 3702 installed inside the first row of waste frames 3701, and a second storage bin 3704 installed inside the second row of waste frames 3703; The tops of the first row of waste frames 3701 and the second row of waste frames 3703 are both provided with funnel-shaped openings; The first storage bin 3702 and the second storage bin 3704 are both made of heat-insulating materials, and the inner walls of the first storage bin 3702 and the second storage bin 3704 are provided with a ceramic layer.

[0030] Preferably, the inner wall of the 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 insulating outer tube 370, the settled dirt can be scraped off efficiently. After the dirt is removed, the heating inner tube 410 cooperates with the insulating outer tube 370 to efficiently oxidize and decompose the inhaled paint mist. After the dirt inside the heating inner tube 410 and the insulating outer tube 370 is scraped off and dropped for storage, the first storage bin 3702 and the second storage bin 3704 can be replaced within a specified time period, thereby ensuring that the paint shop remains clean and tidy to avoid the diffuse paint mist interfering with the vision of workers wearing goggles.

[0031] The working principle and usage process of the present invention are as follows: In the process of painting the front of the vehicle, in addition to mechanical spraying, the special-shaped parts of the vehicle body also need to be painted manually. However, during the manual painting operation, a large amount of paint mist is generated between the vehicle body and the workers. When the workers walk along the periphery of the vehicle body, airflow is generated around the workers, which in turn causes diffuse paint mist to adhere to the workers' clothing. The device is used in conjunction with the handheld spray gun 100. When the worker holds the handheld spray gun 100 and sprays paint on the special-shaped parts of the car body, as the paint mist is continuously released, the paint mist sprayed from the handheld spray gun 100 for a moment will be directly sprayed on the car body, and the paint mist will overflow due to the resistance of the spray in the air and the influence of the airflow around the worker. At the moment the paint mist overflows, the external air pipe is connected to the exhaust pipe 390. As the external air pipe discharges air to the outside, the cavity formed by the exhaust pipe 390, the heat-insulating outer pipe 370 and the heating inner pipe 410 will absorb the paint mist that is sprayed and overflowed from the nozzle of the handheld spray gun 100. At this time, the paint mist that is sprayed and along the center line of the nozzle of the handheld spray gun 100 will be directly sprayed on the car body, and as the shooting distance increases, the overflowed paint mist is actively absorbed by the backflow gas generated by the two filters 380 in an outward-facing "X" structure. At the same time, the coil 420 releases heat energy when it is energized, until the entire heating inner tube 410 continuously releases high temperature outwards. As the absorbed paint mist continues to pass through the outer surface of the heating inner tube 410, the paint mist is oxidized and decomposed under high temperature. The decomposed residues settle on the outer wall of the heating inner tube 410 and the inner wall of the insulating outer tube 370, while the decomposed water and gas continue to be discharged outwards along the gap between the heating inner tube 410 and the insulating outer tube 370, and are finally exhausted from the external air pipe. As the sediment on the outer wall of the heating inner tube 410 and the inner wall of the insulating outer tube 370 continues to increase, the motor 260 is rotated forward and reverse regularly; When the first driving wheel 270 rotates forward, the first driving wheel 270 driven by the transmission shaft in the motor 260 drives the two second driving wheels 360. The second driving wheels 360 and the winding wheel 350 finally pull the cable 440. At this time, the annular scraper 430 moves laterally along the outer wall of the heating inner tube 410 and the inner wall of the insulating outer tube 370. The sediment scraped by the annular scraper 430 is transferred to the first storage bin 3702 and the second storage bin 3704 along the first row of waste frames 3701 and the second row of waste frames 3703 respectively. When the first driving wheel 270 rotates in reverse, the combined winding wheel 350 and the second driving wheel 360 will loosen the cable 440, and under the traction of the high-temperature resistant tension spring 460, the annular scraper 430 will quickly reset, and finally the annular scraper 430 will perform a secondary decontamination on the outer wall of the heating inner tube 410 and the inner wall of the insulating outer tube 370; By arranging two sets of thermal oxidation mechanisms 400 for extracting overflowing paint mist on both sides of the nozzle of the handheld spray gun 100, at the moment the handheld spray gun 100 sprays paint, the paint directly shot along the center line of the nozzle of the handheld spray gun 100 will be accurately attached to the special-shaped parts of the car body, and the paint mist that is away from the center line of the nozzle of the handheld spray gun 100 and overflows will be actively absorbed. At this time, the worker's forward direction can avoid being blocked by the diffuse paint mist, and at the same time reduce the adhesion pollution of the worker's clothes caused by the diffuse paint mist.

[0032] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the claims and their equivalents.
