Description

Technical Field

[0001] This utility model relates to the field of exhaust gas emission equipment technology, and in particular to a low-emission muffler that can be steered in an arc shape. Background Technology

[0002] During industrial production and the operation of machinery and equipment, high-temperature exhaust gases containing noise and harmful substances are often generated. In order to reduce noise pollution and environmental hazards, silencers and exhaust gas purification devices are installed at the exhaust ports of the equipment.

[0003] Existing silencers and purification devices are mostly rigid metal structures with fixed inlet and outlet directions. This fixed structure lacks flexibility in actual installation. When the installation space is limited, or when it is necessary to guide the exhaust gas in a specific direction for collection and discharge, multiple connectors such as elbows and transition pipes are often required to adjust the exhaust path. In addition, the silencer and purification functions are implemented by two or more independent devices, which not only makes the pipeline layout of the entire exhaust system very complicated, increases the number of connection sealing points and increases the risk of leakage, but also makes the overall device bulky, occupies valuable production space, and increases the cost of procurement and maintenance.

[0004] Therefore, this utility model proposes an arc-shaped, low-emission muffler to address the shortcomings of existing technologies. Utility Model Content

[0005] In view of the problems in the existing technology, such as the fixed structure of the muffler which makes it impossible to flexibly adjust the direction of exhaust gas emission, and the separation of the muffler and the purification function which leads to the complex overall structure and large space occupation, this utility model aims to provide a low-emission muffler with an arc-shaped steering mechanism that has been improved and can effectively solve the above problems.

[0006] This utility model provides an arc-shaped steering low-emission muffler, including a docking seat, an exhaust seat, a steering mechanism, and a muffler mechanism.

[0007] The steering mechanism includes an inner tube, an outer tube, and multiple joints disposed between the inner and outer tubes; the noise reduction mechanism includes porous ceramic sheets, glass wool, and activated carbon cakes.

[0008] Furthermore, the outer tube is coaxially sleeved on the outside of the inner tube, and the multiple segments are connected in series to define and support the inner tube and the outer tube to form a flexible structure; the porous ceramic sheet and the glass wool are fixed along the inner wall of the inner tube, and the activated carbon cake is arranged in a manner that places it on the exhaust gas channel inside the docking seat.

[0009] Preferably, the inner tube is a flexible pipe.

[0010] Preferably, the top of the joint is provided with an assembly hook and the bottom is provided with a snap ring, and adjacent joints are connected by their assembly hooks and snap rings.

[0011] Preferably, the porous ceramic sheet is disposed facing the center side of the joint, and the glass wool is disposed facing the connection between adjacent joints.

[0012] Preferably, the docking seat includes a docking flange, and the inner side of the docking flange is provided with a spiral groove; the arc-shaped steerable low-emission muffler also includes a fixing ring for accommodating the activated carbon cake, the outer wall of the fixing ring is provided with threads, and the fixing ring is detachably screwed and fixed to the spiral groove on the inner side of the docking flange through the threads of its outer wall.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model solves the problem in the prior art that the silencer structure is fixed and cannot flexibly adjust the exhaust gas emission direction according to the actual working conditions and spatial layout by setting a steering mechanism consisting of an outer tube, an inner tube and multiple rotatable joints. It achieves the technical effect of enabling the exhaust gas emission direction to be adjusted by a large-angle arc bend, which greatly enhances the installation adaptability and space utilization of the equipment.

[0015] 2. This utility model solves the problem that existing technologies require multiple independent components to achieve the functions of noise reduction, purification and steering, resulting in a large overall structure, complex pipelines and large space occupation. By integrating porous ceramic sheets and glass wool into the inner wall of the steerable inner pipe and setting activated carbon cake at the exhaust gas inlet, this invention achieves the technical effect of highly integrating the functions of noise reduction, purification and steering into one compact structure, effectively simplifying the exhaust system and reducing installation costs.

[0016] 3. This utility model, by adopting a double-layer structure of inner and outer tubes, uses the inner tube to completely isolate the high-temperature, dusty exhaust gas from the joint steering structure set between the inner and outer tubes. This solves the problem that similar flexible pipes, when transporting dusty exhaust gas, will cause the moving joints and curved parts to become stuck and wear due to the accumulation of pollutants, leading to steering failure and shortened lifespan. It achieves the technical effect of protecting the mechanical components of the steering mechanism from exhaust gas pollution, ensuring the long-term stability and reliability of the steering function, and extending the overall service life of the device.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] Example:

[0026] Please refer to Figures 1 to 5 This utility model provides an arc-shaped, low-emission muffler, which aims to solve the problems of existing mufflers having a fixed structure that cannot flexibly adjust the direction of exhaust gas emission, and the separation of muffler and purification functions leading to a complex overall structure.

[0027] like Figure 1 and Figure 2 As shown, the arc-shaped steerable low-emission muffler includes a docking seat 1, an exhaust seat 2, a steering mechanism 3 connecting the docking seat 1 and the exhaust seat 2, and a muffler mechanism 4 disposed on the exhaust gas flow path. The steering mechanism 3 includes an inner tube 35 and an outer tube 31 coaxially sleeved outside the inner tube 35. The interior of the inner tube 35 defines an exhaust gas passage. The steering mechanism 3 also provides multiple interconnected joints 32 between the inner tube 35 and the outer tube 31. The multiple joints 32 define and support the inner tube 35 and the outer tube 31 to form an integral bendable structure. The muffler mechanism 4 includes a porous ceramic sheet 41 and glass wool 42 fixed along the inner wall of the inner tube 35, and also includes an activated carbon cake 44 disposed on the exhaust gas passage inside the docking seat 1.

[0028] To achieve the coordinated operation of arc-shaped steering and noise reduction, this embodiment focuses on the internal mechanical structure of the steering mechanism 3 and the adaptive layout of the components of the noise reduction mechanism 4.

[0029] Please refer to the following carefully. Figures 2 to 4 Multiple segments 32 are connected end-to-end between the inner tube 35 and the outer tube 31. Each segment 32 has an integrally formed assembly hook 33 at its top and an integrally formed snap-fit ​​ring 34 at its bottom. Adjacent segments 32 are connected by their assembly hooks 33 to the snap-fit ​​rings 34 of other segments 32, allowing them to rotate relative to each other. This forms a hinged support frame between the inner tube 35 and the outer tube 31. When the outer tube 31 is pushed by an external force, this support frame bends, thus driving the… The inner tube 35 of the flexible pipe bends synchronously. To adapt to this bending deformation, the porous ceramic sheet 41 in the silencing mechanism 4 is fixed along the inner wall of the inner tube 35 at the position directly opposite the center of each joint 32, while the glass wool 42 is fixed at the position directly opposite the connection between adjacent joints 32. This structure ensures that during the bending process, the porous ceramic sheet 41 is in the area with less deformation, while the glass wool 42 is in the area with concentrated deformation. Thus, while achieving flexible turning, it ensures the structural stability and functional integrity of the silencing material.

[0030] Based on the above embodiments, in order to facilitate the installation and replacement of the activated carbon cake 44 in the silencing mechanism 4, please refer to the following: Figure 1 and Figure 5 The docking seat 1 is provided with an integrally formed docking flange 36, which is used to seal and fix to the exhaust port of external equipment by bolts. A spiral groove 46 is machined on the inner side wall of the docking flange 36. The silencing mechanism 4 also includes a fixing ring 43, which is used to accommodate and fix the activated carbon cake 44. A thread 45 is correspondingly machined on the outer peripheral wall of the fixing ring 43. By screwing the thread 45 on the fixing ring 43 into the spiral groove 46 on the docking flange 36, the fixing ring 43 and the activated carbon cake 44 inside it can be detachably fixed at the exhaust gas inlet of the docking seat 1.

[0031] Working principle: Connect docking seat 1 and discharge seat 2 to the exhaust port of the equipment through docking flange 36 to ensure that the interface is sealed and leak-free. Connect one end of the inner tube 35 of steering mechanism 3 to docking seat 1 and the other end to discharge seat 2. The outer tube 31 is sleeved on the outside of the inner tube 35. Multiple combined joints 32 are placed on the outer tube 31 and the inner tube 35. The assembly hook 33 at the top of the joint 32 is engaged with the snap ring 34 at the bottom. The multiple joints 32 can be bent to complete the assembly of steering mechanism 3.

[0032] The porous ceramic sheet 41 and glass wool 42 of the silencing mechanism 4 are attached to the inner wall of the inner tube 35 and fixed. The porous ceramic sheet 41 is positioned directly opposite the center side of the joint 32, and the glass wool 42 is positioned directly opposite the connection between the joints 32. When bending, the porous ceramic sheet 41 and glass wool 42 are adapted to the bending area.

[0033] The activated carbon cake 44 is assembled inside the fixing ring 43, and the fixing ring 43 is fixed to the spiral groove 46 inside the docking flange 36 by the thread 45 on the outer wall, thus completing the overall installation of the device.

[0034] The exhaust gas generated during equipment operation enters the docking seat 1 from the exhaust port and then flows into the inner pipe 35. The inner pipe 35 separates the interior from the space formed between the inner pipe 35 and the outer pipe 31, preventing the joint 32 from being blocked by dust. The exhaust gas passes through the porous ceramic plate 41, which adsorbs harmful substances as the airflow passes through, while reducing the exhaust gas flow rate and noise. The exhaust gas passes through the glass wool 42, which absorbs noise and filters some impurities in the exhaust gas. The exhaust gas passes through the activated carbon cake 44 twice, which adsorbs harmful gas components in the exhaust gas, achieving low emission treatment.

[0035] If the exhaust gas emission direction needs to be adjusted, push the outer pipe 31. The outer pipe 31 drives the joint 32 to rotate. The assembly hook 33 between the joints 32 remains connected to the snap ring 34. The inner pipe 35 bends synchronously with the outer pipe 31. The emission seat 2 is aligned with the target emission direction. Stop pushing the outer pipe 31. The joint 32 maintains the current angle to achieve the arc-shaped turning function, thus meeting the equipment's requirements for noise reduction and harmful gas adsorption.
