Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection devices, in particular to a liquid medium collecting structure of an exhaust gas filter discharger and the exhaust gas filter discharger. Background Art

[0002] In the process of model making, spray painting is an indispensable step. However, the waste gas and paint mist generated by spray painting will pollute the working environment and cause health hazards to the human body. For this reason, relevant personnel have developed a water curtain discharge device to remove waste gas and paint mist through extraction and adsorption.

[0003] For example, the utility model designed, developed and authorized by the applicant in the early stage (name: "Desktop Small Exhaust Gas Filter and Emission Machine", announcement number: CN216856092U, announcement date: 20220701).

[0004] As attached Figure 1 and attached Figure 2 As shown, when the desktop small-scale exhaust gas filter and discharge machine is working, the water tank 6' is filled with clean water, then placed in the tray 61', and pushed into the innermost side of the shell 2'. During the process of pushing the water tank 6', the water curtain plate 4' and the negative pressure cabin plate 3' are synchronously lowered, and the inclined lower end of the water curtain plate 4' and the inlet end of the submersible pump 7' are submerged below the liquid level in the water tank 6'. Turn on the submersible pump 7', and the water in the water tank 6' is sent into the overflow tank, and a water curtain is formed on the water curtain plate 4'. Turn on the induced draft fan 1' to suck the gas in the shell 2'. The spray gun is pointed at the water curtain plate 4' for spraying paint, and the excess exhaust gas paint mist particles are captured by the water curtain, and the reflected exhaust gas paint mist is sucked into the fan-shaped negative pressure working area for discharge. When changing the water, remove the operating table 8', pull out the tray 61' and the water tank 6', the negative pressure cabin plate 3', the water curtain plate 4' and the submersible pump 7' are synchronously lifted, and then the water tank 6' can be removed.

[0005] However, the desktop small exhaust gas filtration and emission machine also has the following problems: (1) The water tank is a completely open structure, and the clean water containing exhaust gas and paint mist temporarily stored in it is easy to evaporate; (2) The water tank is placed on a pallet, and the pallet needs to be pulled out and the negative pressure cabin plate, water curtain plate and submersible pump need to be lifted simultaneously before the water tank can be removed, which makes the overall structure more complicated and places higher reliability requirements on the slide rail. In addition, the clean water containing exhaust gas and paint mist temporarily stored in the water tank is easy to spill during the pulling process. Utility Model Content

[0006] The utility model aims to provide a liquid medium collection structure of an exhaust gas filter discharger and an exhaust gas filter discharger, which abandons an open water storage tank and is designed to use a closed structure liquid storage box and a partition to collect the liquid medium. The closed structure liquid storage box can reduce the volatilization of the liquid medium. At the same time, the liquid storage box is directly inserted into the shell, and the tray and the slide rail are eliminated. The pull-out structure is simpler, and there is no need to design an auxiliary mechanism for synchronous lifting of the curtain plate, etc., so the overall structure is simpler.

[0039] 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.

[0040] The embodiments of the utility model are described in detail below with reference to the accompanying drawings.

[0041] This embodiment provides a liquid medium collection structure of an exhaust gas filter discharger, as shown in the attached Figure 3 ~Attached Figure 5 As shown in , it is intended to simplify the overall structure while reducing the volatilization of the liquid medium and avoiding the spillage of the liquid medium.

[0042] Specifically, the liquid medium collecting structure of the exhaust gas filter discharger includes a substantially rectangular parallelepiped housing 100, as shown in the attached Figure 6 and attached Figure 7 As shown in . The front side of the shell 100 is open. A partition 110 is provided below the curtain plate 200 which is installed obliquely from the rear side wall to the open front side in the shell 100. The edge of the partition 110 is connected to the inner side wall of the shell 100, and divides the inner area of ​​the shell 100 into independent upper working areas and lower working areas. The upper surface of the partition 110 or the entire part of the partition 110 is recessed to form a confluence groove 111. The inclined lower end of the curtain plate 200 faces the reflux groove 111. A through drain port 112 is provided at the bottom of the reflux groove 111. The shape of the drain port 112 can be a circular hole, a polygonal hole or a waist-shaped hole. The liquid medium (such as water) used to capture the exhaust paint mist flows along the upper surface of the curtain plate 200 to form a liquid curtain, and finally flows into the confluence groove 111 and is discharged from the drain port 112. The liquid medium collection structure of the exhaust gas filter discharger also includes a liquid storage tank 300, as shown in the attached Figures 8-10As shown. The liquid storage box 300 is generally a closed structure, a part of which can be inserted into the lower working area, and the rest of it is located outside the lower working area. A liquid inlet 311 is provided on the upper surface of the portion of the liquid storage box 300 located in the lower working area. The shape of the liquid inlet 311 is generally consistent with the shape of the liquid discharge port 112, and the opening size is greater than or equal to the opening size of the liquid discharge port 112. The liquid medium discharged from the liquid discharge port 112 enters the liquid storage box 300 through the liquid inlet 311. A working hole 320 is provided on the upper surface of the portion of the liquid storage box 300 located outside the lower working area. Through the working hole 320, a pump can be placed in the liquid storage box 300 to extract the liquid medium in the liquid storage box 300 to the vicinity of the inclined upper end of the curtain plate 200 for recycling.

[0043] In this embodiment, an open water tank is abandoned, and a closed liquid storage box is designed to cooperate with a partition to collect the liquid medium. The closed liquid storage box can reduce the volatilization of the liquid medium. At the same time, the liquid storage box is directly inserted into the shell, and the tray and the slide rail are eliminated. The pull-out structure is simpler, and there is no need to design an auxiliary mechanism for synchronous lifting of the curtain plate, etc., so the overall structure is simpler. In addition, during the pull-out process of the closed liquid storage box, the liquid medium temporarily stored in it is not easy to spill.

[0044] In this embodiment, the upper surface of the portion of the liquid storage box 300 located outside the lower working area is roughly flush with the upper surface of the partition 110, and can be used as a working surface for temporarily placing models or tools. The left and right side surfaces and the bottom surface of the portion of the liquid storage box 300 located outside the lower working area are roughly flush with the left and right side surfaces and the bottom surface of the shell 100. The length and height of the portion of the liquid storage box 300 located in the lower working area are smaller than the length and height of the portion of the liquid storage box 300 located outside the lower working area. Therefore, the liquid storage box 300 as a whole is composed of two rectangular parts of different sizes, and the transition surface between the two forms a limiting surface 330. When the limiting surface 330 is against the open front end surface of the shell 100 during the process of inserting the liquid storage box 300 into the lower working area, the liquid storage box 300 is installed in place.

[0045] In this embodiment, the upper surface of the portion of the liquid storage box 300 located in the lower working area is a trapezoidal depression with a larger upper portion and a smaller lower portion to form a buffer groove 310. The liquid inlet 311 is located at the bottom of the buffer groove 310. After the liquid storage box 300 is inserted into the lower working area, the liquid discharge port 112 faces the buffer groove 310. Therefore, even if the positions of the liquid inlet 311 and the liquid discharge port 112 are offset, it will not affect the liquid medium entering the liquid storage box 300.

[0046] In this embodiment, the lower edge of the drain port 112 extends toward the bottom of the housing 100 to form a guide tube 113. The lower end of the guide tube 113 extends to the top of the bottom of the buffer groove 310. Figure 7As shown in . The guide tube 113 can better guide the liquid medium to the buffer groove 310. At the same time, during the extraction and insertion process of the liquid storage box 300, the buffer groove 310 can also serve as an escape space for the guide tube 113, without affecting the extraction and insertion process of the liquid storage box 300.

[0047] In this embodiment, a sealing plate 120 is provided at the open front side of the lower working area. Figure 6 and attached Figure 7 As shown in . A rectangular installation window 121 is provided on the sealing plate 120. The size of the installation window 121 is roughly matched with the circumferential size of the portion of the liquid storage box 300 located in the lower working area to meet the requirement of inserting the liquid storage box 300 into the shell 100. A portion of the liquid storage box 300 is inserted into the lower working area through the installation window 121, and the remaining portion is located outside the lower working area. There is a larger contact area between the surface of the sealing plate 120 and the limiting surface 330 of the liquid storage box 300, which can better realize the position positioning of the liquid storage box 300 when it is inserted into the shell 100.

[0048] In this embodiment, positioning grooves 122 are formed on both sides of the sealing plate 120. Figure 6 and attached Figure 7 A positioning protrusion 331 is formed at a corresponding position on the limiting surface 330 of the liquid storage box 300, as shown in the attached Fig. 9 As shown in FIG. 1 , during the process of inserting the liquid storage box 300 into the housing 100, the positioning protrusion 331 is gradually inserted into the positioning groove 122. The cooperation between the positioning protrusion 331 and the positioning groove 122 can further improve the stability of the liquid storage box 300 when it is inserted into the housing 100.

[0049] In this embodiment, the portion of the liquid storage box 300 located in the lower working area is arc-shapedly recessed at one end facing the rear side wall of the housing 100, forming an arc-shaped surface 340. Figure 8 As shown in . A protruding arc-shaped support surface 130 is provided on the inner side of the bottom of the housing 300. The arc-shaped support surface 130 can be formed by a depression at the bottom of the housing 100. After the liquid storage box 300 is inserted into the housing 100, the arc-shaped surface 340 contacts the arc-shaped support surface 130 to prevent the liquid storage box 300 from being further inserted, while providing appropriate support for the end of the liquid storage box 300.

[0050] In this embodiment, the lower part of the liquid storage box 300 located outside the lower working area is in an arc transition and has a concave handrail groove 350. The handrail groove 350 can facilitate the pulling out of the liquid storage box 300.

[0051] In this embodiment, the lower edge of the working hole 320 extends into the liquid storage box 300 to form a working chamber 321. Fig.10The lower end of the working chamber 321 is located near the top of the bottom of the liquid storage box 300, and the inner area of ​​the working chamber 321 is connected to the inner area of ​​the liquid storage box 300. The working chamber 321 can better limit the installation position of the pump.

[0052] In this embodiment, a through waste residue opening 360 is provided on the upper surface of the portion of the liquid storage box 300 outside the lower working area. The waste residue opening 360 can be used to pour out waste liquid or to temporarily fix operating tools.
