Description

Technical Field

[0001] This utility model relates to the field of segmented catalyst exhaust pipe technology, and in particular to a segmented catalyst exhaust pipe. Background Technology

[0002] Segmented catalytic converter exhaust pipes are typically designed to improve the maintainability, flexibility, and operational efficiency of catalytic converters. The segmented exhaust pipe design divides the exhaust system into multiple detachable sections, usually employing a modular design. This allows each section to be installed, disassembled, or replaced independently, facilitating catalyst maintenance and replacement. This design is commonly found in industrial catalytic converter production processes.

[0003] Existing technologies, such as the utility model patent with publication number CN222773304U, disclose a segmented catalytic combustion device for a burner. This patent includes a device body, with a first combustion chamber and a second combustion chamber disposed within the inner cavity of the device body. Air pipes are connected through the top of the inner walls of both the first and second combustion chambers. A cooling channel is formed between the inner and outer rings of the second combustion chamber. A fan is mounted on the top of the device body, and multiple heat sinks are evenly arranged on the outer ring of the device body. During catalytic combustion, the fan injects cold air into the cooling channel through the injection pipe. The cold air exchanges heat with the mixed gas in the second combustion chamber, absorbing its heat to cool it and maintain a lower temperature within the second combustion chamber, facilitating smooth catalytic combustion. Simultaneously, the heat sinks dissipate the heat absorbed by the cold air in the cooling channel into the outside air, thus rapidly cooling the mixed gas in the second combustion chamber, accelerating the combustion speed of the fuel gas, and reducing fuel consumption.

[0004] In the catalytic reaction, it was found that during the operation of the catalyst exhaust pipe, the segmented design allows the exhaust pipe to be flexibly adjusted according to different usage requirements. Pipe sections of different lengths or sizes can adapt to equipment of different scales or types. At this time, when installing different segments of the pipe, they are mostly fixed as one piece, which will cause the problem of inconvenience in limiting and disassembling the catalytic exhaust pipe. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the existing technology where, during the operation and use of the catalyst exhaust pipe, the segmented design allows the exhaust pipe to be flexibly adjusted according to different usage requirements. Different lengths or sizes of pipe segments can adapt to different scales or types of equipment. However, when installing different segments of the pipe, they are mostly fixed as one piece, which makes it inconvenient to limit and separate the catalyst exhaust pipe.

[0006] To solve the above technical problems, this utility model provides a segmented catalytic converter exhaust pipe, including: a connecting pipe, a connecting pipe, a catalytic converter canister, an installation device, and an adjusting plate. The catalytic converter canister is disposed on the arc surface of the connecting pipe, and its interior is fixedly connected to the connecting pipe. The connecting pipe is disposed at one end of the connecting pipe via the installation device. An adjusting device is provided on the arc surface of the catalytic converter canister. The adjusting device includes an adjusting frame, which is fixedly connected to the surface of the adjusting plate. A rotating plate is rotatably connected to the inner wall of one end of the adjusting frame. The rotating plate has an arc-shaped cross-section, and its inner wall engages with the surface of the catalytic converter canister. A through hole is formed on one end surface of the rotating plate. The through hole is a vertical hole. A positioning plate is fixedly connected to the surface of the adjusting plate at the position corresponding to the rotating plate. An adjusting rod is fixedly connected to the surface of the positioning plate. The cross-section of the adjusting rod near the positioning plate is cross-shaped. An inlay plate is slidably connected to the arc surface of the adjusting rod. The cross-sectional dimensions of the inlay plate are adapted to the cross-sectional dimensions of the through hole. A slot is formed on one end of the rotating plate at the position corresponding to the through hole. The surface of the inlay plate is engaged with the inner wall surface of the slot. A spring is sleeved on the arc surface of the adjusting rod. The two ends of the spring are fixedly connected to the positioning plate and the inlay plate, respectively.

[0007] The effect achieved by the above components is as follows: during the operation of the entire catalyst exhaust pipe, the position of the entire catalyst exhaust pipe will be fixed and limited. At this time, the surface of the catalyst tank can be supported and protected by the adjustment device, and the positioning operation of the entire exhaust pipe can be facilitated by the docking and limiting between the adjustment frame and the rotating plate.

[0008] Preferably, both ends of one inner wall of the adjusting frame are fitted with coil springs, and the two ends of the coil springs are fixedly connected to the rotating plate and the adjusting frame, respectively.

[0009] The effect achieved by the above components is that the torsional force generated by the coil spring can squeeze and adjust the position of the rotating plate, preventing the rotating plate from shaking.

[0010] Preferably, an auxiliary rod is fixedly connected to one side of the surface of the inlay plate, and the length of the auxiliary rod is adapted to the size of the through hole.

[0011] The effect achieved by the above components is that when the inlay plate is pulled and moved, the auxiliary rod fixed on one side of the inlay plate can be used to assist in the stretching operation.

[0012] Preferably, a compression pad is fixedly connected to the lower surface of the rotating plate, and a protrusion is fixedly connected to the surface of the compression pad, the surface of the protrusion abutting against the arc surface of the catalytic tank.

[0013] The aforementioned components achieve the following effect: the compression pads fixed on the lower surface of the rotating plate can effectively protect the catalytic converter during operation, preventing direct impact damage between the rotating plate and the catalytic converter.

[0014] Preferably, an installation device is provided at the ends of the connecting pipe and the connecting tube that are close to each other. The installation device includes several connecting brackets, one side of which is fixedly connected to the arc surface of the connecting tube. A rotating rod is rotatably connected to the inner wall of the connecting bracket. A pressing shaft is threadedly connected to the arc surface of the rotating rod. A connecting block is fixedly connected to the arc surface of the connecting pipe corresponding to the position of the rotating rod. The cross-section of the connecting block is "U". A pressing sleeve is fixedly connected to the arc surface of the rotating rod. The arc surface of the pressing sleeve is engaged with the inner wall of the connecting block. The same sleeve is inserted at the ends of the connecting pipe and the connecting tube that are close to each other. The cross-sectional dimensions of the sleeve are adapted to the inner wall dimensions of the connecting pipe and the connecting tube.

[0015] The effect achieved by the above components is that during the process of connecting the connecting pipe and the connecting tube, the installation device can be used to operate, and the rotating rod set on the arc surface of the connecting pipe can be used to engage with the connecting block fixed on the arc surface of the connecting tube. At the same time, the pressing shaft can be used to press and fix the pipe.

[0016] Preferably, a limiting frame is fitted onto the arc surface of the rotating rod, and a limiting hole is formed on the surface of the connecting block, with the inner wall of the limiting hole interlocking with the arc surface of one end of the limiting frame.

[0017] The effect achieved by the above components is that, through the insertion between the limiting bracket and the limiting hole, the entire rotating rod can be fixed more firmly.

[0018] Preferably, auxiliary grooves are provided on the arc surfaces at both ends of the sleeve, and auxiliary blocks are fixedly connected to the inner walls of the connecting pipe and the coupling pipe, with the surface of the auxiliary block inserted into the inner wall of the auxiliary groove.

[0019] The above components achieve the following effects: by using the insertion and limiting between the auxiliary groove and the auxiliary block, the position of the sleeve can be prevented from rotating and moving, and the sealing performance can be increased by using the sleeve.

[0020] Compared with related technologies, the segmented catalytic converter exhaust pipe provided by this utility model has the following advantages:

[0021] Beneficial effects:

[0022] By operating the adjustment device, the catalyst tank can be quickly and flexibly adjusted, positioned, and securely locked on-site. With the help of the spring-driven insert plate and the through hole and slot on the rotating plate, the insert plate is pulled to compress the spring, which releases the locking of the rotating plate. The insert plate disengages from the slot and through hole, allowing the rotating plate to rotate freely. After being released, the spring force pushes the insert plate into the through hole and into the slot, firmly locking the rotating plate in the current position, thus effectively fixing and limiting the entire catalyst tank.

[0023] By operating the installation device, a quick, secure, and detachable mechanical connection between the connecting pipe and the butt joint is achieved, ensuring the airtightness of the connection. The sleeve and centering are matched with auxiliary grooves and auxiliary blocks to facilitate the segmented installation, disassembly, and transportation of the pipeline, while ensuring the sealing performance and operational stability of the exhaust system.
