Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1-6 As shown, this utility model provides a technical solution: a paint mist spraying device with exhaust gas treatment, including a water curtain cabinet 1, a water curtain plate 2 is provided inside the water curtain cabinet 1, a placement plate 3 is provided on the side of the water curtain plate 2 inside the water curtain cabinet 1, and an air outlet 4 is provided at the top of the water curtain cabinet 1. A filter frame 5 is provided inside the water curtain cabinet 1 near the bottom of the water curtain plate 2, and the filter frame 5 is welded to the inside of the water curtain cabinet 1. A filter screen 6 is provided inside the filter frame 5. Positioning rods 7 are provided on both sides inside the filter frame 5, and the positioning rods 7 are engaged with the filter screen 6. A horizontal plate 8 is provided at one end of the filter frame 5, and a matching reserved groove is opened on the side of the filter frame 5 near the horizontal plate 8.

[0018] The horizontal plate 8 is designed so that the connected filter screen 6 can be moved out synchronously after the horizontal plate 8 is moved, and the filter screen 6 can be easily removed by pulling the horizontal plate 8.

[0019] like Figure 3 As shown, a fixed frame 9 is provided at one end of the filter frame 5, and an extension plate 10 is provided inside the fixed frame 9. The extension plate 10 is shaped like a "T". A limiting plate 11 is provided at one end of the extension plate 10. The limiting plate 11 is shaped like a "U" and an adjusting handle 12 is welded to one end of the limiting plate 11. A guide rod 13 is connected through one end of the extension plate 10. A limiting spring 14 connected to the inside of the fixed frame 9 is provided at one end of the extension plate 10, and a pin 15 is passed through the top of the limiting plate 11.

[0020] The guide rod 13 ensures that the extension plate 10 is relatively stable when moving, and a rubber block is provided at the bottom of the pin 15, which provides a good locking effect after the pin 15 is inserted.

[0021] In use, first pull the pin 15 upwards, allowing it to be removed from the top of the horizontal plate 8. Then, pull the adjusting handle 12 on one side of the limiting plate 11. Pulling the handle 12 moves the connecting limiting plate 11, which in turn moves the connecting extension plate 10, allowing it to slide on the surface of the guide rod 13. During this movement, the extension plate 10 compresses the connecting limiting spring 14, and the limiting plate 11 loses its restraint on the horizontal plate 8 after movement. The horizontal plate 8 can be pulled upwards, so that the connected filter screen 6 can be moved after the horizontal plate 8 moves. After the filter screen 6 moves, it can move along the positioning rod 7. Then the filter screen 6 can be removed and cleaned. After the filter screen 6 is cleaned, it can be reinstalled and locked by the limiting plate 11. Thus, by setting the filter screen 6, it can filter the falling water and filter the water that adsorbs particles, so that the falling water can be reused. When treating exhaust gas, water resources can also be reused. By periodically adding flocculant into the water curtain cabinet 1 and then circulating it through a water pump on one side, the water containing flocculant can turn the adsorbed paint particles into flocculent paint sludge after forming a water curtain. The flocculent paint sludge is then filtered through the filter screen 6 to prevent it from re-entering the water curtain cabinet 1.

[0022] like Figure 4 and Figure 6 As shown, the filter frame 5 is provided with a rotating rod 16 connected by a bearing at one end near the horizontal plate 8. A rotating gear 17 is provided at one end of the rotating rod 16. A limiting plate 18 is provided at the end of the rotating rod 16 near the rotating gear 17. The limiting plate 18, the rotating gear 17 and the rotating rod 16 are fixedly connected.

[0023] The limiting plate 18 is positioned at the top of the filter screen 6, thereby limiting the position of the filter screen 6.

[0024] like Figure 4 As shown, a rack 19 is provided at one end of the extension plate 10 near the rotating gear 17, and the rack 19 is evenly distributed at one end of the extension plate 10.

[0025] The evenly distributed rack 19 enables the rotating gear 17 to rotate, thereby facilitating the synchronous movement of the limiting plate 18.

[0026] Furthermore, pulling the adjustment handle 12 moves the connected limiting plate 11, which in turn moves the connected extension plate 10. The extension plate 10, in turn, moves the connected rack 19, causing the rack 19 to rotate the rotating gear 17 on one side. The rotating gear 17, in turn, rotates the rotating rod 16, causing the rotating rod 16 to rotate the limiting plate 18 connected to the top. After the limiting plate 11 moves and retracts, it can simultaneously rotate the limiting plate 18. This makes it easier to remove the filter screen 6. After reinstalling the filter screen 6, the limiting plate 18 can restrict the filter screen 6, making it more stable when placed.

[0027] It should be noted that: the water curtain cabinet 1 is equipped with a negative pressure fan, which forces the paint-containing exhaust gas from the paint spraying into the interior of the water curtain cabinet 1. The spray system at the top of the cabinet continuously sprays water downwards, and the water flows evenly along the water curtain plate 2 inside the cabinet, forming a continuous and dense water film. At the same time, some water falls into the bottom water tank, forming a "water curtain" through overflow. When the exhaust gas passes through the water film / water curtain, the liquid paint mist particles in it are adsorbed and adhered by the water film, or dispersed by the impact of the water flow, and fall into the bottom circulating water tank with the water flow, realizing the initial separation of paint mist and air. The exhaust gas that has undergone preliminary treatment by the water film will continue to rise and pass through the "water baffle" at the top of the cabinet to remove the tiny water droplets carried in the airflow. Finally, the purified air is discharged through the fan, realizing the rapid treatment of exhaust gas by the water curtain.

[0028] Working principle: By placing the workpiece on top of the placement plate 3 and then performing the painting operation, the exhaust gas generated during the painting process can be adsorbed and adhered by the water curtain, thus treating the exhaust gas. Subsequently, water containing exhaust gas particles can be introduced into the filter frame 5 and filtered through the filter screen 6 set inside the filter frame 5, so that the particles contained inside can be filtered out, realizing the reuse of water resources and avoiding the need for subsequent water treatment before operation. Furthermore, the setting of the limiting plate 11 and the limiting plate 18 can fix the position of the filter screen 6, so that it can not only treat exhaust gas during use, but also recycle water resources after treatment, which has a good water recycling effect.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
