Description

Technical Field

[0001] This utility model relates to the field of waste gas purification technology, and in particular to a multi-stage waste gas purification treatment device. Background Technology

[0002] Multi-stage exhaust gas purification is a process used in industrial or commercial sectors to treat harmful gases and pollutants, primarily targeting exhaust gases emitted during production processes (such as volatile organic compounds (VOCs), acidic gases, dust, sulfides, nitrogen oxides, etc.). Through physical, chemical, or biological technologies, exhaust gas purification chambers can effectively reduce pollutant concentrations, ensuring emissions meet environmental standards and minimizing harm to the environment and human health. The main components include the chamber itself, a pretreatment system, and the core purification unit, etc.

[0003] Existing technologies, such as the utility model patent with publication number CN216440207U, disclose a multi-stage treatment device for waste gas purification. This utility model discloses a multi-stage treatment device for waste gas purification, including a base, a dust collection box, an adsorption box, and a first filter box. The dust collection box and the adsorption box are respectively mounted on the top two ends of the base via mounting brackets. A UV photolysis lamp is mounted on the top of the dust collection box via screws. Horizontal plates are welded to both ends of the inner wall of the dust collection box, and dust collection bags are fixed between the horizontal plates via screws. An air inlet pipe and a first air outlet pipe are respectively installed on one side of the bottom and one side of the top of the dust collection box through pre-drilled holes. This novel device can efficiently adsorb and settle dust in waste gas, has multiple filtration structures, and can easily and comprehensively filter particulate impurities in waste gas, making it suitable for widespread use.

[0004] The following defects were found in response to the above: In the field of exhaust gas purification, existing technologies often use multi-stage exhaust gas purification boxes to adsorb and purify exhaust gases and harmful gases in the air. They also often need to connect the air inlet pipe to pipes from various sources. However, existing multi-stage exhaust gas purification boxes cannot quickly and accurately connect pipes from various sources, which leads to low work efficiency and increased labor costs. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing multi-stage exhaust gas purification boxes, which cannot quickly and accurately connect pipes from various sources, resulting in low work efficiency and increased labor costs. Therefore, this invention proposes a multi-stage exhaust gas purification treatment device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a multi-stage waste gas purification treatment device, characterized in that: it includes a housing, an inlet pipe, an outlet pipe, and a connecting pipe; the arc surface of the inlet pipe is provided with a docking device, the docking device includes a retaining ring, the retaining ring is slidably connected to the inlet pipe; the arc surface of the retaining ring is fixedly connected to two mounting plates, the two mounting plates are respectively located above and below the retaining ring; two rectangular blocks are fixedly connected to one side of each of the two mounting plates; a round rod is rotatably connected to one end of each of the two rectangular blocks that is close to each other; a circular ring is fixedly connected to the arc surface of the circular rod; springs are fixedly connected to both sides of the circular ring, the springs are fixedly connected to the rectangular blocks; a retaining plate is fixedly connected to the arc surface of the circular ring; two buckles are fixedly connected to the side of the connecting pipe near the retaining ring, the two buckles corresponding to the positions of the mounting plates.

[0007] The effect achieved by the above components is as follows: the clamping plate and the buckles on the upper and lower sides of the connecting pipe are used to lock the pipe in place. At this time, the clamping ring is moved towards the box until the connecting pipe is connected to the air inlet pipe, thereby completing the pipe connection.

[0008] Preferably, a sealing gasket is fixedly connected to one end of the air intake pipe near the connecting pipe, and the sealing gasket has excellent sealing performance.

[0009] The effect achieved by the above components is that after the connecting pipe and the air intake pipe are connected, the sealing gasket can ensure a good seal between the pipes and prevent exhaust gas leakage.

[0010] Preferably, a connecting plate is fixedly connected to the arc surface of the retaining ring, and a screw is threadedly connected to one side of the connecting plate. The end of the screw away from the retaining ring is rotatably connected to the housing.

[0011] The effect achieved by the above-mentioned components is that the retaining ring can be slid on the arc surface of the intake pipe by rotating the screw, thereby reducing labor costs.

[0012] Preferably, three grips are fixedly connected to the end of the screw near the retaining ring, and the ends of the three grips away from the screw are all semi-circular.

[0013] The effect achieved by the above components is that when it is necessary to rotate the screw, the screw is driven to rotate by the three grips, which is more convenient and less labor-intensive.

[0014] Preferably, the inner wall of the box is provided with four mounting devices, each of the four mounting devices including two slide rails. The two slide rails are fixedly connected to the inner wall of the box. The slide rails are U-shaped. The inner walls of the two slide rails are slidably connected to two rectangular strips. The ends of the two rectangular strips that are close to each other are fixedly connected to the same rectangular frame. A rectangular plate is fixedly connected to one side of the rectangular frame. A storage frame is slidably connected to the inner wall of the rectangular frame.

[0015] The effect achieved by the above components is as follows: different air-purifying items can be placed in the storage boxes of the four installation devices. After storage, the storage box is slid into the rectangular frame, and then the rectangular plate is pushed so that the rectangular strip slides into the box along the slide rail. This achieves the effect of being able to place different air-purifying items at the same time and to place them quickly.

[0016] Preferably, both sides of the rectangular frame are fixedly connected to limit rods, and the arc surface of the limit rods is slidably connected to a limit plate.

[0017] The effect achieved by the above components is that when the storage frame is slid into the rectangular frame, the two limiting plates rotate along the arc surface of the limiting rod to both sides of the storage frame, thereby limiting the sliding direction of the storage frame and preventing the storage frame from sliding off the rectangular frame when it encounters vibration.

[0018] Preferably, a handle is fixedly connected to one side of the rectangular plate, and the handle has a U-shaped cross-section.

[0019] The effect achieved by the above components is that the rectangular plate is pushed by the handle, allowing the rectangular frame to slide into the box along the slide rail, which is more convenient and less labor-intensive.

[0020] In summary, the beneficial effects of this utility model are as follows:

[0021] In this invention, a docking device is installed. When exhaust gas purification is required, pipe docking is necessary, that is, the connecting pipe is docked with the air inlet pipe. The two clamping plates are pressed towards each other until they are in the corresponding positions of the buckles on the connecting pipe. At this time, the clamping plates and buckles are fastened together, so that the positions of the connecting pipe and the air inlet pipe are aligned. Then, manually gripping the handle drives the screw to rotate. Because the connecting plate and the screw are threaded together, and because the connecting plate and the retaining ring are fixedly connected, when the screw rotates, the connecting plate will drive the retaining ring to move along the screw towards the housing. At this point, because the ring and rod are fixedly connected to the clamping plate, and the rod is set on the mounting plate, which is fixedly connected to the clamping ring, the clamping ring will move along the intake pipe and move the connecting pipe in the same direction until the connecting pipe and the intake pipe are fully connected. At this point, the clamping plate is released. Since the ring and spring connected to the clamping plate are fixedly connected, and the spring is fixedly connected to the rectangular block, when the clamping plate is released, the two clamping plates will draw arcs upward and downward with the ring as the center, and the two clamping plates will automatically open. The end of the intake pipe near the connecting pipe is fixedly connected to the sealing gasket, which will keep the connecting pipe and the intake pipe sealed after connection and prevent exhaust gas leakage. Holding the rod makes it easier and less strenuous to rotate the screw.

[0022] In this invention, by setting up an installation device, when exhaust gas purification is required, different types of air purification items need to be selected for purification. The required items are categorized and stored in different storage boxes. At this point, the limiting plate at the top of the rectangular frame is rotated upwards along the arc of the limiting rod, allowing the storage box to be placed into the rectangular slot. Then, the limiting plate is rotated downwards, aligning with the two sides of the storage box to prevent it from slipping off the rectangular frame. Next, the handle needs to be manually pushed. Since the rectangular block is fixedly connected to the handle, pushing the handle will also move the entire rectangular frame. It is important to note that when pushing, the rectangular strips on the top and bottom sides of the rectangular frame need to be aligned with the slide rails inside the housing, and the rectangular frame is slid into the housing along the inner wall of the slide rails. This completes the installation operation. The handle helps the operator save effort. Attached Figure Description

[0030] Reference Figure 1As shown, this utility model provides a technical solution: a multi-stage waste gas purification treatment device, including a housing 1, an inlet pipe 2, an outlet pipe 3, and a connecting pipe 6. The arc surface of the inlet pipe 2 is provided with a docking device 4, and the inner wall of the housing 1 is provided with four installation devices 5.

[0031] The specific setup and function of the docking device 4 and the installation device 5 will be described in detail below.

[0032] Reference Figure 2 and Figure 3 As shown in this embodiment: the docking device 4 includes a retaining ring 401, which is slidably connected to the air intake pipe 2. Two mounting plates 402 are fixedly connected to the arc surface of the retaining ring 401. The two mounting plates 402 are located on the upper and lower sides of the retaining ring 401, respectively. Two rectangular blocks 403 are fixedly connected to one side of each of the two mounting plates 402. A round rod 404 is rotatably connected to one end of the two rectangular blocks 403 that is close to each other. A circular ring 405 is fixedly connected to the arc surface of the round rod 404. Springs 406 are fixedly connected to both sides of the circular ring 405. The springs 406 are fixedly connected to the rectangular blocks 403. A retaining plate 407 is fixedly connected to the arc surface of the circular ring 405. Two buckles 408 are fixedly connected to the side of the connecting pipe 6 near the retaining ring 401. The two buckles 408 correspond to the positions of the mounting plates 402. The retaining ring 401 is secured by the clips 408 on both sides of the connecting pipe 6 using the clamping plate 407. Then, the retaining ring 401 is moved towards the housing 1 until the connecting pipe 6 aligns with the intake pipe 2, thus completing the pipe connection. A sealing gasket 409 is fixedly connected to the end of the intake pipe 2 near the connecting pipe 6, providing excellent sealing. After the connecting pipe 6 and intake pipe 2 are aligned, the sealing gasket 409 ensures a tight seal between the pipes, preventing exhaust gas leakage. A connecting plate 410 is fixedly connected to the arc surface of the retaining ring 401. A screw 411 is threaded onto one side of the connecting plate 410, and the end of the screw 411 away from the retaining ring 401 is rotatably connected to the housing 1. Rotating the screw 411 allows the retaining ring 401 to slide on the arc surface of the intake pipe 2, reducing labor costs. Three levers 412 are fixedly connected to the end of the screw 411 near the retaining ring 401. The ends of the three levers 412 away from the screw 411 are all semi-circular. When it is necessary to rotate the screw 411, the three levers 412 drive the screw 411 to rotate, which is more convenient and less labor-intensive.

[0033] Reference Figure 4 , Figure 5 and Figure 6As shown in this embodiment: each of the four installation devices 5 includes two slide rails 51, which are fixedly connected to the inner wall of the housing 1. The slide rails 51 are U-shaped, and two rectangular strips 52 are slidably connected to the inner walls of the two slide rails 51. The ends of the two rectangular strips 52 that are close to each other are fixedly connected to the same rectangular frame 53. A rectangular plate 54 is fixedly connected to one side of the rectangular frame 53, and a storage frame is slidably connected to the inner wall of the rectangular frame 53. Different air-purifying items can be placed in the storage frames 55 of the four installation devices 5. After storage, the storage frame is slid into the rectangular frame 53, and then the rectangular plate 54 is pushed so that the rectangular strips 52 slide into the housing 1 along the slide rails 51, achieving the effect of simultaneously placing different air-purifying items and placing them quickly. Limiting rods 56 are fixedly connected to both sides of the rectangular frame 53, and the arc surface of the limiting rods 56 is slidably connected to a limiting plate 57. After the storage frame 55 is slid into the rectangular frame 53, the two limiting plates 57 are rotated along the arc surface of the limiting rod 56 to both sides of the storage frame 55, which restricts the sliding direction of the storage frame 55 and prevents the storage frame 55 from slipping off the rectangular frame 53 due to vibration. A handle 58 is fixedly connected to one side of the rectangular plate 54, and the cross-section of the handle 58 is "U". Using the handle 58 to push the rectangular plate 54 makes the rectangular frame 53 slide into the box 1 along the slide rail 51, which is more convenient and less labor-intensive.

[0034] Working principle: In this utility model, by setting up a docking device 4, when exhaust gas purification is required, pipe docking is necessary, that is, connecting pipe 6 and air inlet pipe 2 are docked. The two clamping plates 407 are pressed towards each other, pressed into the position of the corresponding buckle 408 on the connecting pipe 6. At this time, the clamping plates 407 and buckles 408 are fastened to each other, so that the positions of the connecting pipe 6 and the air inlet pipe 2 correspond. Then, manually gripping the handle 412 drives the screw 411 to rotate. Since the connecting plate 410 and the screw 411 are threadedly connected, and since the connecting plate 410 and the retaining ring 401 are fixedly connected, when the screw 411 rotates, the connecting plate 410 will drive the retaining ring 401 to move along the screw 411 towards the housing 1. At this time, because the ring 405, which is fixedly connected to the clamping plate 407, is fixedly connected to the round rod 404, and the round rod 404 is set on the mounting plate 402, and the mounting plate 402 is fixedly connected to the retaining ring 401, the retaining ring 401 will move along the intake pipe 2 and move the connecting pipe 6 in the same direction until the connecting pipe 6 is fully connected to the intake pipe 2. At this time, the clamping plate 407 is released. Since the ring 405 and the spring 406 connected to the clamping plate 407 are fixedly connected, and the spring 406 is fixedly connected to the rectangular block 403, when the clamping plate 407 is released, the two clamping plates 407 will draw arcs upward and downward with the ring 405 as the center, so that the two clamping plates 407 will automatically open. The end of the intake pipe 2 near the connecting pipe 6 is fixedly connected to the sealing gasket 409, which will keep the connecting pipe 6 and the intake pipe 2 sealed and prevent exhaust gas leakage. The gripping rod 412 makes it more convenient and less strenuous to rotate the screw 411.

[0035] In this utility model, by setting up the installation device 5, when exhaust gas purification is required, it is necessary to select different types of air purification items for purification. The required items are categorized and stored in different storage boxes 55. At this time, the limiting plate 57 located at the upper end of the rectangular frame 53 is rotated upward along the arc surface of the limiting rod 56 so that the storage box 55 can be placed in the rectangular groove. Then, the limiting plate 57 is rotated downward to correspond to the two sides of the storage box 55 to prevent the storage box 55 from slipping off the rectangular frame 53. Next, the handle 58 needs to be manually pushed. Since the rectangular block 403 is fixedly connected to the handle 58, pushing the handle 58 will also move the entire rectangular frame 53. It should be noted that when pushing, the rectangular strips 52 located on the upper and lower sides of the rectangular frame 53 need to be aligned with the slide rail 51 inside the box 1, and the rectangular frame 53 is slid into the box 1 along the inner wall of the slide rail 51. This completes the installation operation. The handle 58 helps the operator save effort.

[0036] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection within a component, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
