Description

Technical Field

[0001] This utility model relates to the technical field of waste gas purification devices, and in particular to a waste gas purification combustion device. Background Technology

[0002] Exhaust gases often contain harmful substances such as nitrogen oxides, sulfur dioxide, and formaldehyde. These substances pose a threat to human health and may cause diseases such as asthma and lung cancer, as well as irritation and allergic reactions to the eyes and respiratory tract. By purifying exhaust gases, the emission of these harmful substances can be reduced, thereby protecting public health and human health.

[0003] Referring to the public announcement (CN221839725U), which describes a waste gas purification and combustion device, the bevel gear in that design is located in front of the filter assembly. This gear is inevitably affected by impurities, easily leading to jamming or damage. Furthermore, it lacks a spare filter assembly for flexible replacement, resulting in time-consuming replacements and prolonged downtime for the equipment, thus affecting the waste gas purification efficiency. To address these issues, a new waste gas purification and combustion device is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a waste gas purification and combustion device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A waste gas purification and combustion device includes an exhaust pipe and a fixing rod installed on the device body. A connecting frame is sleeved on the fixing rod. A positioning frame extending into the interior of the connecting frame is slidably disposed through the connecting frame by an elastic mechanism. The fixing rod is provided with an annular groove corresponding to the positioning frame. Two positioning grooves are provided on the arc-shaped inner wall of the annular groove. Two mounting rings are installed on the connecting frame. An opening corresponding to the mounting ring is provided on the exhaust pipe. A filter assembly is provided on the mounting ring through an installation mechanism.

[0007] Preferably, the elastic mechanism includes a spring sleeved on the rod of the positioning frame, with both ends of the spring connected to the outer wall of the positioning frame head and the arc-shaped outer wall of the connecting frame, respectively.

[0008] Preferably, the installation mechanism includes a plurality of installation blocks disposed on the filter assembly, and the installation ring is provided with installation grooves corresponding to the installation blocks.

[0009] Preferably, the positioning frame is provided with a gripping rod, which is rotatably mounted on the positioning frame.

[0010] Preferably, the two mounting rings and positioning grooves are circumferentially distributed at equal intervals, and the surface of the mounting block is provided with a rubber pad with anti-slip texture.

[0011] Preferably, the mounting ring is provided with a retaining ring, which is positioned opposite the filter assembly.

[0012] The beneficial effects of this utility model are:

[0013] The unique installation mechanism design, including the combination of mounting rings, mounting grooves, mounting blocks, and rubber pads, allows for easy installation and removal of the filter assembly on the exhaust pipe. Cleaning or replacement can be performed with simple operations, significantly reducing maintenance difficulty and time costs, and improving the maintainability of the equipment.

[0014] By utilizing the synergistic effect of the elastic mechanism and the annular and positioning grooves on the positioning frame, connecting frame, and fixing rod, the two mounting rings and filter components can be quickly swapped during equipment operation. Simply shutting down the equipment body briefly, lifting the positioning frame, and rotating the connecting frame allows the used filter component to be moved to the outside for subsequent cleaning, while simultaneously switching the spare filter component to the working position. This significantly reduces equipment downtime and improves operational efficiency and continuity.

[0015] The retaining ring on the mounting ring can effectively collect the parts that fall off during the process of the filter component intercepting impurities, keeping them between the filter component and the retaining ring. This prevents impurities from falling directly into the exhaust pipe and causing pollution, reduces the impact of impurity accumulation on the performance of the exhaust pipe and the overall operational stability of the equipment, and lowers the risk of equipment failure and cleaning difficulty.

[0016] The gripping rods mounted on the positioning frame facilitate the lifting operation of the positioning frame by the operator, making the separation and repositioning of the positioning frame between the annular groove and the positioning groove more convenient and efficient. This further improves the convenience and controllability of the entire filter assembly switching and maintenance operation, reduces the labor intensity and operation difficulty of the operator, and helps to improve the user-friendliness and operation safety of the equipment.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4 A waste gas purification and combustion device includes an exhaust pipe 1 and a fixing rod 2 installed on the device body. This solution refers to the public disclosure (announcement) number: CN221839725U, which is specifically a waste gas purification and combustion device. Only the exhaust pipe 1 is improved; therefore, the attached drawings of this solution only show the structure of the improved part. The rest can be referred to the above-mentioned solution disclosure.

[0024] A connecting frame 7 is fitted on the fixed rod 2. A positioning frame 8 is slidably installed on the connecting frame 7 through an elastic mechanism and extends into the interior of the connecting frame 7. The fixed rod 2 is provided with an annular groove 11 corresponding to the positioning frame 8. Two positioning grooves are provided on the arc-shaped inner wall of the annular groove 11. Two mounting rings 3 are installed on the connecting frame 7. An opening 6 corresponding to the mounting ring 3 is provided on the exhaust pipe 1. A filter assembly 4 is provided on the mounting ring 3 through an installation mechanism.

[0025] The elastic mechanism includes a spring 9 sleeved on the rod of the positioning frame 8. The two ends of the spring 9 are connected to the outer wall of the head of the positioning frame 8 and the arc-shaped outer wall of the connecting frame 7, respectively. The positioning frame 8 is approximately T-shaped. The elastic potential energy provided by the spring 9 enables the head of the positioning frame 8 to be dragged, ensuring that its rod is within the annular groove 11. Therefore, the connecting frame 7 cannot detach from the fixed rod 2, and the head of the positioning frame 8 is located in the positioning groove within the annular groove 11, so the connecting frame 7 cannot rotate on the fixed rod 2.

[0026] The mounting mechanism includes multiple mounting blocks 13 mounted on the filter assembly 4. The mounting ring 3 has mounting grooves 12 corresponding to the mounting blocks 13. The surface of the mounting block 13 is provided with a rubber pad with anti-slip texture. The mounting block 13 is inserted into the mounting groove 12 with the help of the rubber pad, ensuring that the filter assembly 4 can be stably mounted on the mounting ring 3. The mounting block 13 on the filter assembly 4 inside the opening 6 is blocked by the inner wall of the opening 6 on one side and restricted by the mounting groove 12 on the other side. Therefore, the filter assembly 4 cannot fall off or move from the top cover of the mounting ring 3. The exposed filter assembly 4 can be disassembled by simply moving it laterally to detach the mounting block 13 from the mounting groove 12.

[0027] The positioning frame 8 is equipped with a gripping rod 10, which is rotatably mounted on the positioning frame 8. Lifting the gripping rod 10 will lift the positioning frame 8, causing its rod to disengage from the annular groove 11 or the positioning groove. When the rod of the positioning frame 8 is disengaged from the positioning groove but not from the annular groove 11, grasping the gripping rod 10 will cause the positioning frame 8 and the connecting frame 7 to rotate on the fixed rod 2, thereby enabling the interchange of the two mounting rings 3.

[0028] The two mounting rings 3 and the positioning grooves are circumferentially evenly spaced. This circumferential even spacing facilitates the rotation and replacement of the mounting rings 3 and the filter assembly 4.

[0029] The mounting ring 3 is equipped with a retaining ring 5, which is positioned opposite the filter assembly 4. The side of the filter assembly 4 facing the main body of the equipment will intercept a lot of impurities. Any impurities that fall off will remain between the filter assembly 4 and the retaining ring 5 and will not fall off easily. They can be carried out by the mounting ring 3 for cleaning, thus preventing contamination of the inside of the exhaust pipe 1.

[0030] When using this utility model, referring to the publication (announcement) number: CN221839725U, it is specifically a waste gas purification and combustion device. According to the above-mentioned scheme, the waste gas discharged to the exhaust pipe 1 will be filtered by the filter component 4. The intercepted impurities are located between the filter component 4 and the baffle ring 5. After the filter component 4 has been used for a period of time, it needs to be cleaned or replaced. At this time, the device body is closed, and then the positioning frame 8 is lifted so that its rod is disengaged from the current positioning groove, but not from the annular groove 11. Then, the connecting frame 7 is rotated relative to the fixed rod 2. The connecting frame 7 can drive the two mounting rings 3 to rotate, thereby realizing the replacement of the mounting rings 3 and the filter component 4. After the replacement is completed, the positioning frame 8 is released so that its rod enters another positioning groove. If the rod of the positioning frame 8 is also disengaged from the annular groove 11, and the two mounting rings 3 and the filter component 4 are all outside the exhaust pipe 1, the above components can be disassembled.

[0031] By tapping the external filter assembly 4 and inserting your hand from one end of the retaining ring 5, you can apply force to one end of the filter assembly 4 to disassemble the mounting block 13 from the mounting groove 12, thereby disassembling the filter assembly 4. After disassembly, it is easier to clean and replace it.

[0032] This design allows the equipment to be turned off simply by rotating and replacing the filter assembly 4, resulting in a short shutdown time. If a spare filter assembly 4 is unavailable and is installed using bolts, then the process of shutting down, disassembling, removing, replacing, and re-secured would be required, leading to a prolonged shutdown time.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
