[0002] Fluorocarbon spraying is an advanced surface treatment method that uses a special coating containing fluoropolymers as its main component. This coating is known for its excellent weather resistance, corrosion resistance, wear resistance, and self-cleaning properties. It is particularly suitable for various material surfaces exposed to the outside for a long time, such as building facades and metal structures.

[0003] Fluorocarbon spraying not only sprays fluorocarbon paint on the surface of the object, but also produces a large amount of waste gas. The waste gas contains a large number of substances that are harmful to animals and plants, directly polluting the ecological environment and endangering the health of production workers. Therefore, a new type of fluorocarbon spraying waste gas treatment device is needed. Utility Model Content

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0025] See also Figure 1-4 , a fluorocarbon spraying waste gas treatment device, including a spray box 1. The openings at both ends of the spray box 1 are provided with an air intake valve assembly 4 with adjustable opening size. The spray box 1 is penetrated by a conveying chain 2, and the conveying chain 2 passes through the openings of the two air intake valve assemblies 4 at the same time. The opening size of the air intake valve assembly 4 is adjusted according to the overall thickness of the device to be fluorocarbon sprayed. Several hangers 3 for hanging devices to be fluorocarbon sprayed are fixedly connected below the conveying chain 2, and the several hangers 3 are linearly and evenly distributed. Two hooks are provided at the bottom of each hanger 3, and the two hooks hang the device to be fluorocarbon sprayed at the same time to prevent the device to be fluorocarbon sprayed from spinning when moving, affecting the fluorocarbon spraying. Each air intake valve assembly 4 is connected to two hoses 5. An absorption tank 7 is installed on the top of the spray box 1, and the absorption tank 7 is equipped with two tees 6, and the horizontal pipe openings of each tee 6 are connected to the hose 5. Each tee pipe 6 is equipped with a foaming device at its bottom opening. An air intake pipe extends from the top of the absorption tank 7. This intake pipe is connected to a vacuum pump to exhaust air to the outside. During operation, absorption liquid is added to the absorption tank 7 to completely immerse the foaming device. The air in the hose 5, containing fluorocarbon spray waste gas, passes through the foaming device and is dispersed into small bubbles that fully contact the absorption liquid, allowing the absorption liquid to fully absorb the fluorocarbon spray waste gas.

[0026] Each air suction door assembly 4 includes: two door seats 401 arranged in a mirror image and fixedly connected to the inner wall of the spray box 1. Each door seat 401 is horizontally slidably mounted with a movable door plate 402. Each movable door plate 402 is fixedly connected to a strip-shaped air suction head 403, and the strip-shaped air suction holes of the two strip-shaped air suction heads 403 are arranged opposite to each other. Each strip-shaped air suction head 403 is connected to a hose 5. Each strip-shaped air suction head 403 is fixedly connected to a threaded seat 404, and the two threaded seats 404 are commonly threadedly connected to a forward and reverse threaded rod 405, and the internal threads of the two threaded seats 404 are opposite. The forward and reverse threaded rod 405 is rotatably connected to the spray box 1, and one end of the forward and reverse threaded rod 405 extending out of the spray box 1 is coaxially fixedly connected to a turntable 406. By rotating the turntable 406, the forward and reverse threaded rod 405 can be used to make the two strip-shaped air suction heads 403 approach or separate from each other. The distance between the two strip-shaped air suction heads 403 is determined by the overall thickness of the device to be fluorocarbon sprayed.

[0027] The foaming device is a porous cage 8, which is threadedly connected to the three-way pipe 6, and the top outer contour of the porous cage 8 is hexagonal. The gas squeezed out of the porous cage 8 is dispersed into small bubbles and enters the absorption liquid.

[0028] A liquid filling port is provided on the top of the absorption tank 7, and a liquid discharge pipe extends from the bottom of the absorption tank 7. The liquid filling port of the absorption tank 7 is sealed with a screw cap, and the liquid discharge pipe of the absorption tank 7 is sealed with a flange and a sealing plate.

[0029] A one-way air inlet valve 9 is installed on the top of the spray box 1 and is arranged between the two air intake valve assemblies 4. Due to the continuous air intake of the air intake valve assemblies 4, the air pressure in the inner cavity of the spray box 1 decreases, and air enters the inner cavity of the spray box 1 through the one-way air inlet valve 9, thereby balancing the air pressure in the inner cavity of the spray box 1 with the external air pressure. The air in the inner cavity of the spray box 1 is continuously sucked away by the air intake valve assemblies 4.

[0030] Working principle:

[0031] Before fluorocarbon spraying, according to the overall thickness of the device to be fluorocarbon sprayed, the turntable 406 is rotated through the forward and reverse threaded rods 405 to make the two strip-shaped suction heads 403 approach or separate from each other, so that the distance between the two strip-shaped suction heads 403 and the fluorocarbon spraying device is as small as possible, thereby reducing the leakage of fluorocarbon spraying exhaust gas from the spray box 1;

[0032] During fluorocarbon spraying, the hanger 3 on the conveying chain 2 hangs the fluorocarbon spraying device to be moved into the spray box 1 for fluorocarbon spraying, and at the same time, the top suction pipe of the absorption tank 7 is connected to the vacuum pump to exhaust to the outside, so that the two strip suction heads 403 continuously inhale the fluorocarbon spraying waste gas in the inner cavity of the spray box 1, making it difficult for the fluorocarbon spraying waste gas to leak from the opening of the suction door assembly 4, and then the air containing the fluorocarbon spraying waste gas enters the absorption tank 7 through the hose 5 and the tee pipe 6. The air containing the fluorocarbon spraying waste gas passes through the porous cage 8 at the bottom of the tee pipe 6 and is dispersed into small bubbles and fully contacts the absorption liquid, so that the absorption liquid fully absorbs the fluorocarbon spraying waste gas, and the remaining air is discharged through the top suction pipe of the absorption tank 7.

[0033] It should be noted that the above content only illustrates the technical idea of ​​the utility model and cannot be used to limit the protection scope of the utility model. For ordinary technicians in this technical field, they can make several improvements and modifications without departing from the principles of the utility model. These improvements and modifications all fall within the protection scope of the claims of the utility model.
