Description

Technical Field

[0001] This utility model relates to the field of environmental pollution technology, specifically to a device for testing the purification performance of environmental pollutants. Background Technology

[0002] Vehicle exhaust emissions are a major source of environmental pollution, containing pollutants such as nitrogen oxides and sulfides. Reducing the emission of these gases is crucial for environmental protection, and a series of tests are needed to determine how to reduce or degrade them.

[0003] Currently, most equipment for detecting environmental pollutant content is designed for single pollutants and cannot dynamically test the concentration of multiple air pollutants. Furthermore, it lacks the experimental conditions for combined physical adsorption decomposition, chemical degradation, and photocatalytic degradation. Consequently, it cannot test the degradation effect of materials with environmental pollutant degradation functions on environmental pollutants under the action of multiple degradation methods, which affects the accuracy of research on pollutant degradation conditions and increases the difficulty of such research.

[0004] To overcome the aforementioned shortcomings, existing technology (Chinese patent application number: CN113030397B, application date: 2021-03-26) discloses an environmental pollutant purification performance testing device, including a test chamber body, a controller, a carbon monoxide concentration sensor, a hydrocarbon concentration sensor, a nitrogen oxide concentration sensor, and a sulfur dioxide concentration sensor. The controller is fixed to the front outer surface of the test chamber body by screws, and the carbon monoxide concentration sensor, hydrocarbon concentration sensor, nitrogen oxide concentration sensor, and sulfur dioxide concentration sensor are respectively arranged on both sides of the controller. This invention facilitates the testing of the concentration changes of various harmful components in exhaust gases from materials with environmental pollutant degradation functions under the action of various degradation methods, and facilitates the testing and evaluation of the material's performance in reducing harmful components in exhaust gases.

[0005] While the existing design can solve the above problems, the design of the sprinkler device is too simple, it cannot effectively control different groups individually, and it is somewhat lacking in the design for purification tests of different pollutants, with incomplete types. Furthermore, the effect of the main filtration design is not presented intuitively enough. Utility Model Content

[0006] The purpose of this utility model is to provide an environmental pollutant purification performance testing device to solve the problems mentioned in the background art, such as the design of the water spraying device being too simple, not being able to effectively control different groups individually, and the design being slightly insufficient for the purification tests of different pollutants, with incomplete types, and the effect of the main filtration design not being presented intuitively enough.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an environmental pollutant purification performance testing device, comprising a control panel mounted on the outer surface of the mounting housing, concentration sensors mounted on the left and right sides of the control panel, an opening and closing plate mounted at the upper opening of the mounting housing, and a meshing transmission mechanism for transmitting water spray heads mounted above the opening and closing plate, the meshing transmission mechanism comprising a first transmission pipe, a second transmission pipe mounted on the outer surface of the first transmission pipe, a limit fixing bracket mounted on the outer surface of the second transmission pipe, the limit fixing bracket being fixedly mounted on the upper surface of the mounting housing, a start-stop block mounted on the outer surface of the second transmission pipe, a sliding inner groove being provided above the start-stop block, a rotating gate mounted on the side of the start-stop block, and a first gear mounted on the outer surface of the rotating gate;

[0008] The mounting housing is equipped with a support frame, and the support frame is equipped with a rotating engagement mechanism that drives the degradation filter plate.

[0009] Furthermore, the rotating engagement mechanism includes a drive motor, which is fixedly installed inside the support frame. The output end of the drive motor is equipped with a meshing gear, and a second gear is installed on the side of the meshing gear.

[0010] Furthermore, a nested mounting plate is installed at the center of the second gear, and a degradation filter plate is installed inside the nested mounting plate. Four sets of degradation filter plates are installed at equal intervals about the center of the nested mounting plate, and rotating fixing frames are installed at the upper and lower ends of the nested mounting plate. The nested mounting plate is rotatably installed inside the rotating fixing frames, and the rotating fixing frames are fixedly installed on the inner surface of the mounting shell.

[0011] Furthermore, a start / stop gear plate is installed on the side of the first gear, and the start / stop gear plate is slidably installed inside the sliding inner groove. The first transmission pipe, the second transmission pipe, and the start / stop block are internally connected to each other, and the start / stop gear plate intercepts the inside of the second transmission pipe. A water spray head is installed on the lower surface of the second transmission pipe, and the water spray head passes through the top of the mounting housing and acts on the inside of the mounting housing.

[0012] Furthermore, three sets of the second transmission pipes are symmetrically installed about the center point of the first transmission pipe, and a protective shell is installed above the second transmission pipe. The protective shell is fixedly installed on the upper surface of the opening and closing plate, and the rotating gate and the first gear are integrated into one piece.

[0013] Furthermore, the outer surface of the first gear contacts the outer surface of the start-stop gear plate to form a meshing structure, and four sets of water spray heads are equidistantly installed about the center point of the second transmission pipe, and the inner surface of the sliding inner groove contacts the outer surface of the start-stop gear plate to form a sliding structure.

[0014] Furthermore, the nested mounting plate and the second gear are designed as a single unit, and the outer surface of the meshing gear contacts the outer surface of the second gear to form a meshing structure.

[0015] Compared with the prior art, the beneficial effects of this utility model are: when the environmental pollutant purification performance testing device needs to perform water spraying operation, the gate rotates along the inside of the start-stop block. The rotating gate drives the integrated first gear to start rotating. While the first gear is rotating, it slides along the inside of the sliding inner groove due to the meshing motion, and gradually makes the second transmission pipe connect with the inside of the start-stop block, completing the process of the second transmission pipe delivering water to the inside of the spray head. This design allows the water volume and the amount of water at different locations to be controlled.

[0016] Furthermore, when it is necessary to perform internal moisture and gas filtration and detection operations, the drive motor is started using the control panel. The drive motor drives the meshing gear to start rotating in a circle, and as the meshing gear rotates, the second gear in contact with it starts to rotate synchronously. The second gear drives the nested mounting plate, which is fixed at the center position, to rotate along the inside of the rotating fixed frame to perform the filtration and decomposition work. This design makes the decomposition and filtration process simpler.

[0017] Furthermore, three sets of second transmission pipes are distributed on the surface of the first transmission pipe, and four sets of water spray heads are distributed below the second transmission pipes. This design allows for regional control by providing water assistance at different locations, and the water volume and position can be adjusted appropriately as needed. Attached Figure Description

Detailed Implementation

[0025] 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.

[0026] Example 1: Please refer to Figure 1-6 The present invention provides the following technical solution: an environmental pollutant purification performance testing device, comprising a mounting shell 1, a control panel 2, and a drive motor 23.

[0027] A control panel 2 is mounted on the outer surface of the mounting housing 1, and concentration sensors 3 are mounted on the left and right sides of the control panel 2. An opening plate 11 is mounted at the upper opening of the mounting housing 1, and a meshing transmission mechanism for transmitting water to the spray head 14 is mounted above the opening plate 11. The meshing transmission mechanism includes a first transmission pipe 6, and a second transmission pipe 7 is mounted on the outer surface of the first transmission pipe 6. A limit fixing bracket 8 is mounted on the outer surface of the second transmission pipe 7, and the limit fixing bracket 8 is fixedly mounted on the upper surface of the mounting housing 1. A start-stop block 9 is mounted on the outer surface of the second transmission pipe 7, and a sliding inner groove 15 is opened above the start-stop block 9. A rotating gate 10 is mounted on the side of the start-stop block 9, and a first gear 16 is mounted on the outer surface of the rotating gate 10.

[0028] The housing 1 is equipped with a support frame 22, and the support frame 22 is equipped with a rotating engagement mechanism that drives the degradation filter plate 19.

[0029] like Figure 1 , Figure 3 , Figure 4The technical solution shown discloses the following to address the problem of inconvenient water volume control: a start / stop gear plate 17 is installed on the side of the first gear 16, and the start / stop gear plate 17 is slidably installed inside the sliding inner groove 15. The first transmission pipe 6, the second transmission pipe 7, and the start / stop block 9 are internally connected to each other, and the start / stop gear plate 17 intercepts the interior of the second transmission pipe 7. A water spray head 14 is installed on the lower surface of the second transmission pipe 7, and the water spray head 14 passes through the top of the mounting shell 1 and acts inside the mounting shell 1. Three sets of second transmission pipes 7 are symmetrically installed about the center point of the first transmission pipe 6, and a protective shell 5 is installed above the second transmission pipe 7. The protective shell 5 is fixedly installed on the upper surface of the opening and closing plate 11. The rotating gate 10 and the first gear 16 are integrated into one piece. The outer surface of the first gear 16 contacts the outer surface of the start / stop gear plate 17 to form a meshing structure. Four sets of water spray heads 14 are equidistantly installed about the center point of the second transmission pipe 7. The inner surface of the sliding inner groove 15 contacts the outer surface of the start / stop gear plate 17 to form a sliding structure.

[0030] When auxiliary watering is required, firstly, exhaust gas is introduced into the concentration sensor 3, and then a water source is connected to the back of the first transmission pipe 6. When watering assistance is needed, the gate 10 is rotated along the side of the start / stop block 9. As the gate 10 rotates, the first gear 16 fixedly mounted on its outer surface rotates synchronously. During the rotation of the first gear 16, the start / stop gear plate 17, which is in contact with the first gear 16, is driven to mesh. Due to the meshing motion, the start / stop gear plate 17 slides up and down along the sliding inner groove 15 opened at the corresponding position on the start / stop block 9. As the start / stop gear plate 17 slides, the second transmission pipe 7 gradually engages with the interior of the start / stop block 9. The water is connected and flows from the first transmission pipe 6 into the second transmission pipe 7. After entering the second transmission pipe 7, it continues to flow into the spray head 14, which is connected to the second transmission pipe 7. The opening of the spray head 14 inside the housing 1 provides water assistance. The limiting and fixing bracket 8 nested on the outer surface of the second transmission pipe 7 provides fixation and ensures stable operation. Three sets of second transmission pipes 7 are distributed on the surface of the first transmission pipe 6, and four sets of spray heads 14 are distributed below the second transmission pipes 7 to better control the water volume. The protective housing 5 is supported by a stabilizing bracket 4. The ultraviolet lamp 12 fixed above the opening and closing plate 11 also performs disinfection and inspection work.

[0031] like Figure 2 , Figure 5 , Figure 6The technical solution shown discloses the following to address the problem of unstable operation in the purification and filtration design: a rotating meshing mechanism includes a drive motor 23, which is fixedly installed inside a support frame 22. A meshing gear 13 is installed at the output end of the drive motor 23, and a second gear 21 is installed on the side of the meshing gear 13. A nested mounting plate 20 is installed at the center of the second gear 21, and a degradation filter plate 19 is installed inside the nested mounting plate 20. Four sets of degradation filter plates 19 are equidistantly installed about the center of the nested mounting plate 20. Rotating frames 18 are installed at the upper and lower ends of the nested mounting plate 20. The nested mounting plate 20 is rotatably installed inside the rotating frames 18, and the rotating frames 18 are fixedly installed on the inner surface of the mounting housing 1. The nested mounting plate 20 and the second gear 21 are integrated into one piece, and the outer surface of the meshing gear 13 contacts the outer surface of the second gear 21 to form a meshing structure.

[0032] When it is necessary to test the purification performance of exhaust gas and other environmental pollutants, the drive motor 23 is started through the control panel 2. The drive motor 23 is fixed inside the support frame 22. After the drive motor 23 is started, it drives the meshing gear 13 fixedly installed at the drive end to rotate in a circle. The rotation of the meshing gear 13 causes the second gear 21, which is in contact with each other on the side, to mesh. The second gear 21 rotates in a reciprocating circle due to the meshing motion. The rotation of the second gear 21 drives the nested mounting plate 20, which is fixedly installed at the center position, to move synchronously. Inside the nested mounting plate 20, four sets of degradation filter plates 19 are nested. The four sets of degradation filter plates 19 are equidistant from the center position of the nested mounting plate 20. Since the transmission motion of the second gear 21 rotates in a reciprocating circle inside the rotating frame 18, and a set of rotating frames 18 is installed at each of the upper and lower ends of the nested mounting plate 20, the rotational stability of the nested mounting plate 20 is ensured.
