Description

Technical Field

[0001] This utility model relates to the field of muffler connection technology, specifically a muffler transition connection filter mechanism. Background Technology

[0002] A silencer is a device that allows flowing media to pass through while effectively suppressing noise propagation. It is installed in pipes through which flowing media pass, such as high-pressure gas vents, intake or exhaust pipes of ventilators, blowers, air compressors, and engines, and ventilation and air conditioning ducts. The performance evaluation of silencers includes three aspects: noise reduction performance, aerodynamic performance, and regenerated noise. A silencer refers to a noise reduction device that can be used in airflow pipes that also transmit noise. It can be used to attenuate or reflect the noise in the pipe by using pipes with sound-absorbing linings, bends, or pipes with sudden changes in cross-sectional area and other discontinuous acoustic impedance. The former is called a resistive silencer, and the latter is called a reactive silencer. There are also composite impedance silencers.

[0003] An investigation revealed a Chinese utility model patent (CN214551826U) disclosing a silencer filter for a negative pressure Roots blower. The filter includes a cylinder, an air inlet, an air outlet, and a filter device. The cylinder is positioned on a horizontal plane and contains a baffle that divides the interior into two airflow channels. The air inlet and outlet are symmetrically positioned on the cylinder and are both connected to the interior. The filter device is located at one end of the cylinder and is connected to it. This utility model reduces noise through a sound-absorbing layer and provides effective double air filtration through the filter device, improving filtration efficiency. It also features a simple structure and is easy to maintain.

[0004] The aforementioned patent has a problem where the filter mechanism shakes when used by the user, which reduces its reliability and makes it less effective when multi-stage filtration is required, thus affecting the user's ability to use the filter mechanism.

[0005] Therefore, this utility model provides a muffler transition pipe filter mechanism to solve the above problems. Utility Model Content

[0016] (III) Beneficial Effects

[0017] This utility model provides a filter mechanism for a muffler transition pipe. A sleeve ring is installed on the main body of the filter mechanism, and a mounting plate with multiple installation openings is connected to one side of the sleeve ring. Operators can use bolts or other fasteners to pass through the installation openings to quickly and flexibly install the entire filter mechanism to the appropriate position on the muffler transition pipe. The design of multiple installation openings means that the installation process is not limited by a single angle or position, and can be selected according to actual installation needs, greatly improving installation efficiency. At the same time, the mechanism adopts a unique positioning structure. The positioning plate is arranged around the filter mechanism main body with connecting blocks as the center point. The side-mounted plug plate is connected to it by multiple return springs. When the filter mechanism is connected to other components, the plug plate is squeezed and moves against the elastic force of the return springs. After it is aligned with the plug slots of other components, the return springs restore their elastic force and push the plug plate into the plug slots to achieve a stable plug-in positioning. This method of using return springs to achieve automatic positioning of the plug plate is not only convenient to install, but also ensures the stability of the connection, avoids loosening of the connection due to vibration and other reasons, improves the reliability of the entire muffler transition pipe system, and meets the user's needs for convenient installation, stable positioning, improved installation efficiency and connection reliability.

[0018] This utility model provides a filter mechanism for a muffler transition pipe. Through a multi-stage filtration structure consisting of an inner protective layer, a first filter layer, and an inner connecting filter sleeve, the medium entering the muffler transition pipe is filtered layer by layer. When the gas or liquid medium to be filtered enters from the inlet / outlet pipe assembly, it first passes through the inner protective layer. This inner protective layer can block larger particulate impurities, such as dust and iron filings, playing a preliminary filtration role and preventing these impurities from damaging subsequent filter layers, thus extending the service life of the filter mechanism. Next, the medium enters the first filter layer, which has a smaller pore size and can further filter out smaller particulate impurities in the medium, such as tiny dust particles. The filter removes oil particles and other contaminants, improving the purity of the medium. Finally, the medium enters the inner connecting filter sleeve, which may employ special filter materials or structures, such as multi-layer filters or activated carbon adsorption layers, to perform finer filtration, removing even smaller impurities and odor molecules. This ensures the medium achieves a higher standard of cleanliness. The clean medium, after multi-stage filtration, flows out through the inlet and outlet pipe assembly and enters the subsequent section of the muffler's transition pipe. This multi-stage filtration structure effectively improves the purity of the medium, reduces the impact of impurities on the muffler, ensures the normal operation and performance of the muffler, and meets the user's requirements for effectively improving medium purity and ensuring muffler performance.

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.

[0028] Please see Figure 1-5 The present invention provides a technical solution: a muffler transition pipe filter mechanism, including a filter mechanism body 1, a sleeve ring 2 fixedly connected to one side of the filter mechanism body 1, a connecting block 6 fixedly connected to one side of the filter mechanism body 1, and a positioning plate 5 fixedly connected to one side of the connecting block 6.

[0029] In this embodiment, a plug-in opening 9 is provided on one side of the positioning plate 5, and the plug-in opening 9 is connected to the plug-in plate 8. The plug-in plate 8 is connected to the positioning plate 5 through a reset spring 7, and there are multiple reset springs 7.

[0030] like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, a reset spring 7 is fixedly connected to one side of the positioning plate 5, and a plug-in plate 8 is fixedly connected to one side of the reset spring 7.

[0031] In this embodiment, the positioning plate 5 is connected to the filter mechanism body 1 through the connecting block 6, and the positioning plate 5 is arranged around the filter mechanism body 1 as the center point. The mounting plate 3 is fixedly connected to one side of the sleeve ring 2, and the mounting plate 3 is connected to the filter mechanism body 1 through the sleeve ring 2.

[0032] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, an inner protective layer 10 is fixedly connected to one side of the filter mechanism body 1, a first filter layer 11 is fixedly connected to one side of the inner protective layer 10, an inner connecting filter sleeve 12 is fixedly connected to one side of the first filter layer 11, and an inlet and outlet pipe assembly 13 is fixedly connected to one side of the inner connecting filter sleeve 12.

[0033] In this embodiment, a mounting opening 4 is provided on one side of the mounting plate 3, and there are multiple mounting openings 4.

[0034] like Figure 1-5 As shown, when a user needs to use a muffler transition pipe filter mechanism, the sleeve ring 2 is fixedly connected to one side of the filter mechanism body 1, and the mounting plate 3 is fixedly connected to the sleeve ring 2. Thus, the mounting plate 3 is indirectly connected to the filter mechanism body 1 through the sleeve ring 2. The mounting plate 3 has multiple installation openings 4. In actual installation, the operator places the filter mechanism in a suitable installation position on the muffler transition pipe, and uses bolts or other fasteners to pass through the installation openings 4 to fix the mounting plate 3 to the external equipment or mounting base, thereby achieving a stable installation of the entire filter mechanism in the muffler transition pipe system. The design of multiple installation openings 4 makes the installation process more flexible, and the appropriate installation position and angle can be selected according to the actual installation requirements. The positioning plate 5 and the connecting block 6 are connected and positioned: the positioning plate 5 is connected to the filter mechanism body 1 through the connecting block 6, and the positioning plate 5 is arranged around the filter mechanism body 1 as the center point. This surrounding arrangement allows the positioning plate 5 to provide positioning functions in multiple directions. The positioning plate 5 has a plug-in opening 9 on one side, and the plug-in plate 8 is connected to the positioning plate 5 through multiple return springs 7.

[0035] In its initial state, the return spring 7 is in its naturally extended state, pushing the plug plate 8 to a certain position at the plug-in opening 9. When the filter mechanism needs to be connected to other components, such as another part of the muffler transition pipe, the other components have plug-in slots that match the plug plate 8. When the operator brings the filter mechanism close to the other components, the plug plate 8 will be squeezed by the other components, overcoming the elastic force of the return spring 7 and moving towards the positioning plate 5. At this time, the return spring 7 is compressed. When the plug plate 8 moves to the position aligned with the plug-in slot of the other component, the return spring 7 restores its elastic force, pushing the plug plate 8 into the plug-in slot, thus achieving... The filter mechanism is securely connected to other components. This method of using a return spring 7 to move and position the connector plate 8 makes installation more convenient and ensures connection stability. When disassembly is required, simply apply external force to disengage the connector plate 8 from the connector slot, and the return spring 7 will be compressed again to complete the disassembly. The inner protective layer 10 provides preliminary filtration: An inner protective layer 10 is fixedly connected to one side of the filter mechanism body 1. When the gas or liquid to be filtered enters the filter mechanism from the inlet / outlet pipe assembly 13, it first passes through the inner protective layer 10. The inner protective layer 10 has a certain porous structure, which can block… The first filter layer 11 blocks larger particulate impurities, such as dust and iron filings, preventing them from entering subsequent filter layers and protecting them, thus extending the service life of the entire filter mechanism. Further filtration by the first filter layer 11: The media, after initial filtration by the inner protective layer 10, enters the first filter layer 11. The first filter layer 11 has a smaller pore size than the inner protective layer 10, further filtering out smaller particulate impurities, such as tiny dust particles and oil particles, improving the purity of the media. Fine filtration by the inner connecting filter sleeve 12: The media filtered by the first filter layer 11 then enters the inner connecting filter sleeve. 12. The inner connecting filter sleeve 12 may use special filter materials or structures, such as multi-layer filter screens, activated carbon adsorption layers, etc., which can perform finer filtration of the medium, remove smaller impurities, odor molecules, etc., and ensure that the cleanliness of the medium reaches a higher standard. The medium flow of the inlet and outlet pipe assembly 13: the clean medium after fine filtration by the inner connecting filter sleeve 12 flows out of the filtration mechanism through the inlet and outlet pipe assembly 13 and enters the subsequent part of the silencer transition pipe to complete the entire filtration process. At the same time, when new medium needs to be filtered, the medium to be filtered flows into the filtration mechanism through the inlet and outlet pipe assembly 13 to realize the circulation filtration of the medium.
