[0034] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0035] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention.

[0036] The embodiments of the utility model are described in detail below with reference to the accompanying drawings.

[0037] This embodiment provides a liquid distribution structure of an exhaust gas filter discharger, as shown in the attached Figure 3 and attached Figure 4 This liquid distribution structure is designed to improve the distribution of the liquid curtain, so as to better capture the exhaust paint mist.

[0038] Specifically, the liquid distribution structure includes a rectangular curtain plate 100, as shown in the attached Figure 7 As shown. When the curtain plate 100 is arranged in a hollow rectangular shell with an open front side of the exhaust gas filter discharger, the whole is arranged in an inclined state, and the inclination direction of the curtain plate 100 is from the rear side wall inside the shell to the lower open front side. The liquid medium (such as water) flows from top to bottom along the upper surface of the curtain plate 100, thereby forming a liquid curtain on the upper surface of the curtain plate 100 to capture the exhaust gas paint mist. A liquid storage tank 200 is arranged at the inclined upper end of the curtain plate 100 along the length direction of the curtain plate 100 (that is, the direction roughly perpendicular to the flow direction of the liquid medium on the curtain plate 100), as shown in the attached Figure 3 and attached Figure 4 As shown in . The length of the liquid storage tank 200 is roughly the same as the length of the curtain plate 100. A through rectangular overflow port 210 is opened on the liquid storage tank 200 along its own length direction. The length of the rectangular overflow port 210 is roughly the same as the length of the curtain plate 100. The width of the rectangular overflow port 210 is roughly 0.1~5cm. At the same time, the lower edge of the rectangular overflow port 210 is flush with the upper surface of the curtain plate 100. The upper edge of the rectangular overflow port 210 is serrated, as shown in the attached Figure 4 ~Attached Figure 6Two liquid inlets 220 are also provided on the rear side wall of the liquid storage box 200 , through which liquid medium can be input into the liquid storage box 200 .

[0039] In this embodiment, the improved liquid distribution structure is installed in the housing of the exhaust gas filter discharger, and clean water is used as the liquid medium of the exhaust gas paint mist. When the clean water enters the liquid storage tank 200 from the liquid inlet 220, it is then discharged from the rectangular overflow port 210, and forms a water curtain on the upper surface of the curtain plate 100 to capture the exhaust gas paint mist. Due to the influence of the jagged upper edge of the rectangular overflow port 210, the clean water can cover the entire upper surface of the curtain plate 100, that is, there is no empty area without water curtain on the left and right sides of the curtain plate 100, so that the water curtain does not affect the capture of the exhaust gas paint mist.

[0040] Compared with the prior art, the liquid distribution structure in this embodiment is improved, especially the shape of the rectangular overflow port on the liquid storage tank is improved, and a serrated upper edge is added. After the liquid medium flows through the rectangular overflow port, the state of the liquid curtain formed on the upper surface of the curtain plate is improved, avoiding the formation of empty areas without liquid curtain on the left and right edges of the curtain plate, which affects the liquid curtain's capture of exhaust gas paint mist.

[0041] As attached Figure 4 and attached Figure 7 As shown in FIG. 1 , in this embodiment, baffles 110 are provided on both sides of the length direction of the curtain plate 100. On the one hand, the baffles and the screws passing through the baffles can realize that the curtain plate is tilted as a whole in the housing of the exhaust gas filter discharger; on the other hand, the baffles can also play a role in restraining the liquid medium, preventing the liquid medium from flowing out from the left and right sides of the curtain plate.

[0042] In this embodiment, the liquid storage tank 200 is filled with filter cotton or filter sponge (not shown in the figure), and the filter cotton or filter sponge can filter the recycled liquid medium to remove large particles of impurities carried by it, thereby extending the use time of the liquid medium.

[0043] In this embodiment, the liquid storage box 200 includes a groove-shaped housing 230 and a liquid baffle 240. Figure 5 As shown in . The length of the groove housing 230 is roughly the same as the length of the curtain plate 100, and the whole is arranged along the length direction of the curtain plate 100. The front side of the groove housing 230 (i.e., the side facing the open front side of the housing) is completely open. The inclined upper end of the curtain plate 100 is connected to the lower edge of the open side of the groove housing 230. The upper edge of the open side of the groove housing 230 is bent toward the inner area of ​​the groove housing 230 to form a mounting portion 231, as shown in the attached Figure 7As shown in . The length of the liquid baffle plate 240 is roughly the same as the inner length of the trough shell 230, and it is arranged in the open front area of ​​the trough shell 230. The upper part of the liquid baffle plate 240 is connected to the mounting portion 231 by bolts, and the lower part is bent and faces the upper surface of the curtain plate 100. The gap between the lower end of the liquid baffle plate 240 and the upper surface of the curtain plate 100 forms a rectangular overflow port 210. At the same time, the lower end edge of the liquid baffle plate 240 is processed into a serrated shape, as shown in the attached Figure 8 As shown in . In this embodiment, the liquid storage tank is designed as a split structure. On the one hand, it is convenient to replace the filter cotton or filter sponge filled in the liquid storage tank; on the other hand, the width of the rectangular overflow port 210 (i.e., the distance between the lower end of the liquid baffle plate 240 and the upper surface of the curtain plate 100) can be adjusted through the matching relationship between the groove-shaped shell 230 and the liquid baffle plate 240. For example, by changing the width of different liquid baffle plates 240, the distance between the lower end of the liquid baffle plate 240 and the upper surface of the curtain plate 100 is changed. For another example, as shown in the attached Figure 6 and attached Figure 8 As shown, a waist-shaped hole 241 is provided on the upper portion of the liquid baffle plate 240, and the length direction of the waist-shaped hole 241 points to the upper surface direction of the curtain plate 100. By adjusting the position of the bolt in the waist-shaped hole 241, the distance between the lower end of the liquid baffle plate 240 and the upper surface of the curtain plate 100 can be fine-tuned.

[0044] In this embodiment, for the convenience of processing, the curtain plate 100, the baffle plate 110 and the groove-shaped housing 230 can be formed in one piece, for example, by cutting a piece of stainless steel plate into a specified shape and size and then bending it.
