It mainly deposits a uniform metal coating on the metal surface through electric current to improve the corrosion resistance, wear resistance and decorativeness of the metal. During the electroplating process, some harmful gases and vapors will be generated, such as hydrogen cyanide, chromic acid vapor, etc. These harmful substances are very harmful to the human body and the environment. Therefore, in the production process of the electroplating line, it is necessary to use an efficient exhaust device to discharge harmful gases and vapors in time to ensure the cleanliness and safety of the production environment.

The utility model is to set a special double-layer exhaust gas collection device on the electroplating tank, that is, the exhaust device described in this embodiment; the area of ​​the air suction port is increased, and a reversible air duct baffle is added to the suction hood to achieve effective capture of exhaust gas when the workpiece 9 is out of the tank, and the entire electroplating line is closed to collect residual exhaust gas again to ensure that the exhaust gas on the production line does not enter the air.

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Reference Figure 1 - Figure 4, the utility model provides an embodiment: a high-efficiency exhaust device for an electroplating line, comprising an air bin 1, a fan 2 is fixedly connected to the interior of the air bin 1, a detector 3 is fixedly connected to the interior of the air bin 1, a filter screen 23 is fixedly connected to the interior of the air bin 1, an air duct 4 is fixedly connected to the outer wall of the air bin 1, a filter bin 5 is fixedly connected to one end of the air duct 4, a water tank 6 is provided inside the filter bin 5, an atomizing assembly is arranged inside the filter bin 5, an electric guide rail 8 is fixedly connected to the interior of the filter bin 5, a motor 9 is fixedly connected to the output end of the electric guide rail 8, a gear 10 is fixedly connected to the output end of the motor 9, the outer wall of the motor 9 is slidably connected to the interior of the filter bin 5, a slide plate 11 is slidably connected to the interior of the filter bin 5, a rack 12 is fixedly connected to the outer wall of the slide plate 11, the rack 12 is meshed with the gear 10, a filter plate 13 is slidably connected to the inner wall of the slide plate 11, and the atomizing assembly comprises a water pipe 24, the outer wall of the water pipe 24 is fixedly connected to the interior of the filter bin 5, and an atomizing nozzle 7 is fixedly connected to the interior of the water pipe 24;

[0034] Specifically, first, the fan 2 is driven to start working to suck the external air into the wind bin 1. In this process, the filter 23 plays a key role and can effectively filter out large particles of dust in the air to prevent blockage inside the equipment and ensure the smoothness and cleanliness of the air. Then, inside the wind bin 1, the detector 3 performs a detailed detection of the inhaled air. The detector 3 can accurately identify various components in the air and provide accurate data support for subsequent processing. Then, the air that has been preliminarily processed is transported to the inside of the filter bin 5 through the air duct 4. At the same time, the water pipe 24 starts working to guide the water in the water tank 6 to the atomizing nozzle 7 for atomization treatment. The atomized water droplets are delicate and uniform and can be fully combined with the air, providing favorable conditions for the subsequent filtering process. At this time, according to the detection result of the detector 3, the electric guide rail 8 starts to move, accurately driving the motor 9 and the gear The wheel 10 moves up and down in the vertical direction until it moves to the side of the filter plate 13 that needs to be used. In this process, the precise control of the electric guide rail 8 ensures that the gear 10 can accurately mesh with the rack 12. Once the gear 10 is successfully meshed with the rack 12, the motor 9 starts to drive the gear 10 to rotate. The rotation of the gear 10 is transmitted to the filter plate 13 through the rack 12, so that it can move smoothly to the inside of the filter bin 5. The filter plate 13 can then efficiently filter harmful substances in the air. Finally, the air that has been subjected to multiple filtration treatments is discharged through the exhaust port 22. Since each rack 12 is adjusted by the rotation of the gear 10 during the entire process, and the gear 10 is controlled by the vertical up and down movement of the electric guide rail 8, the entire filtration system can achieve highly flexible and precise adjustment to meet the air filtration needs under different circumstances.

[0035] Reference Figure 1 , Figure 5 and Figure 6The outer wall of the slide plate 11 is fixedly connected with a fixed block 14, and the interior of the fixed block 14 is rotatably connected with an L-shaped barb 15. An exhaust port 22 is arranged inside the filter bin 5, and the outer wall of the filter bin 5 is fixedly connected with a limit plate 21, and the interior of the L-shaped barb 15 is fixedly connected with a rotating shaft 16. The interior of the rotating shaft 16 is rotatably connected with a fixed rod 17, and both ends of the fixed rod 17 are fixedly connected to the interior of the fixed block 14. The outer wall of the fixed rod 17 is sleeved with a torsion spring 18, one end of the torsion spring 18 is fixedly connected to the interior of the fixed block 14, and the other end of the torsion spring 18 is fixedly connected to the interior of the rotating shaft 16. The interior of the fixed block 14 is threadedly connected with a screw 19, and one end of the screw 19 is fixedly connected to a limit block 20, and the outer wall of the limit block 20 is slidably connected to the interior of the fixed block 14, and the limit block 20 fits with the L-shaped barb 15;

[0036] Specifically, by pulling the L-shaped hook 15 to rotate inside the fixing block 14, not only the L-shaped hook 15 can be flexibly moved, but also the reversal of the torsion spring 18 is triggered. When the L-shaped hook 15 is rotated to a predetermined angle, the filter plate 13 can be smoothly pulled out from the fixing structure, realizing a convenient disassembly process. When installing the filter plate 13, the operation is also simple. It is only necessary to align the filter plate 13 with the top of the slide plate 11 and then gently push it in. As the filter plate 13 gradually enters the top of the slide plate 11, the raised part of the L-shaped hook 15 is pressed under the action of the torsion spring 18. , will naturally fit on the outer wall of the filter plate 13, which not only ensures the stability of the filter plate 13, but also realizes the preliminary fixation thereof, and then driving the screw 19 to rotate inside the fixing block 14 becomes a key step. As the screw 19 rotates, the limit block 20 will gradually approach and fit the L-shaped hook 15, which not only limits the further movement of the L-shaped hook 15, but also enhances its fixing effect on the filter plate 13. The filter plate 13 is firmly installed in place, ensuring its stability and reliability during use, and realizing the rapid disassembly and assembly of the filter plate 13.

[0037] Working principle: When the electroplating line high-efficiency exhaust device is needed, the fan 2 is first driven to suck the external air into the wind bin 1. In this process, the large dust particles in the air are filtered through the filter 23 to prevent internal blockage. At the same time, the air is detected by the detector 3 inside the wind bin 1, and then the air is sent to the inside of the filter bin 5 through the air duct 4. At this time, the water inside the water tank 6 is atomized through the atomizing nozzle 7 through the water pipe 24 and then sprayed into the inside of the filter bin 5 to combine with the air. At the same time, the detection result of the detector 3 controls the electric guide rail 8 to drive the electric The motor 9 and the gear 10 move up and down to the side of the filter plate 13 to be used, and mesh with the rack 12, and then the motor 9 is started to drive the gear 10 to rotate, so that the filter plate 13 is driven by the rack 12 to move to the inside of the filter bin 5 to filter harmful substances in the air, and finally discharged through the exhaust port 22. In this process, each rack 12 is adjusted by the rotation of the gear 10, and the gear 10 is vertically moved up and down by the electric guide rail 8, so that the gear 10 can mesh with the outer wall of the rack 12;

[0038] In addition, by pulling the L-shaped barb 15 to rotate inside the fixing block 14 and reversing the torsion spring 18, the filter plate 13 can be pulled out after rotating to a certain angle. During installation, the filter plate 13 only needs to be placed above the slide plate 11. When the filter plate 13 is completely placed above the slide plate 11, the torsion spring 18 is no longer subjected to force to rotate, thereby driving the raised portion of the L-shaped barb 15 to fit against the outer wall of the filter plate 13 to fix the filter plate 13, and then driving the screw 19 to rotate inside the fixing block 14, thereby driving the limit block 20 to fit against the L-shaped barb 15, restricting the L-shaped barb 15 and fixing it, thereby achieving the disassembly and assembly of the filter plate 13.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
