Description

Technical Field

[0001] The utility model relates to the technical field of silencers, in particular to a labyrinth silencer. Background Art

[0002] A silencer, as a specially designed device, can not only significantly weaken the propagation of sound, but also precisely control the noise generated by air-powered equipment while ensuring smooth gas flow. In the field of noise reduction, it plays an irreplaceable and important role. It is especially suitable for equipment with high noise such as blowers, air compressors, boiler exhaust ports, generators, and water pumps. In addition, silencers are also widely used in devices such as automobile exhaust systems and firearms. Their high noise reduction ability greatly reduces the potential threat of noise to human health and environmental quality, creating a more peaceful and comfortable living environment for us.

[0003] Existing silencers generally adopt a grid-type outer shell and use an internal filter element as the key noise reduction component, mainly absorbing and weakening noise through the filter mesh. However, the filter mesh is vulnerable to blockage by dust and debris. Over time, it may gradually hinder the smooth operation of the equipment and reduce its working efficiency, causing the inner core of the silencer to freeze, thus having an adverse impact on the long-term performance of the system. Therefore, the utility model provides a labyrinth silencer to solve the problems raised in the above background art. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages existing in the prior art, and a labyrinth silencer is proposed. When noise enters the silencing main body through the installation main body, the external silencing plate and the internal silencing plate inside it reflect and absorb the noise multiple times, thereby reducing the noise.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A labyrinth silencer includes an installation main body and a silencing main body. The installation main body includes an air inlet hole, a connecting column, an installation shell, a plurality of through holes, and two clamping blocks;

[0007] The silencing main body includes a silencing outer shell, a plurality of air outlet grooves, a plurality of external silencing plates, an internal silencing plate, two connecting grooves, and a clamping strip;

[0008] Through the above technical solution, after the air flow is introduced from the air inlet hole of the installation main body, it immediately shuttles inside the silencing main body. The intricate labyrinth channels formed by the internal silencing plate and the external silencing plate of the silencing outer shell cause the air flow to experience frequent turning and reflection processes, thereby converting and dissipating sound energy, and effectively weakening the noise, completing the refined operation of noise control.

[0009] Further, the upper end of the installation shell is fixedly arranged at the lower end of the connecting column, and the intake hole is externally opened inside the connecting column and the installation shell;

[0010] Through the above technical solution, the gas enters the interior of the installation shell through the intake hole in the installation main body and the connecting column.

[0011] Further, a plurality of the through holes are externally opened inside the installation shell, and opposite sides of the two clamping blocks are fixedly arranged on both sides inside the installation shell;

[0012] Through the above technical solution, the through holes can slow down the flow rate of the gas, and the clamping blocks are fixed inside the installation shell, facilitating the connection between the installation shell and the sound-absorbing outer shell, and the operation is convenient.

[0013] Further, the lower end of the clamping strip is fixedly arranged at the upper end of the sound-absorbing outer shell, and the two connecting grooves are externally opened on both sides of the clamping strip;

[0014] Through the above technical solution, by aligning the clamping blocks with the connecting grooves and then rotating the installation shell to rotate it outside the clamping strip on the sound-absorbing outer shell, the connection operation between the installation shell and the sound-absorbing outer shell is realized.

[0015] Further, the lower end of the inner sound-absorbing plate is fixedly arranged at the lower end inside the sound-absorbing outer shell, and the lower ends of a plurality of the outer sound-absorbing plates are all fixedly arranged at the lower end inside the sound-absorbing outer shell;

[0016] Through the above technical solution, when the gas enters the sound-absorbing main body, it first encounters the inner sound-absorbing plate, and then passes through the gaps formed with the outer sound-absorbing plates, causing the gas to reflect and disperse the sound waves multiple times, thereby achieving noise reduction.

[0017] Further, a plurality of the air outlet grooves are externally opened on one side inside the sound-absorbing outer shell, and the two clamping blocks are externally slidably arranged on the outside of the clamping strip;

[0018] Through the above technical solution, the gas is discharged through a plurality of air outlet grooves. At this time, the flow rate and noise of the gas have been greatly reduced. When the clamping blocks are connected to the clamping strip, the connection between the installation main body and the sound-absorbing main body is realized.

[0019] Further, the lower end of the installation main body is rotatably arranged at the upper end of the sound-absorbing main body, and a thread is fixedly arranged on the outside of the connecting column;

[0020] Through the above technical solution, the thread on the outside of the connecting column can be used for connection and fixation with other devices.

[0021] The utility model has the following beneficial effects:

[0022] A labyrinth muffler proposed by the present utility model. When installing the labyrinth muffler, align the clamping blocks inside the installation shell with the clamping strips on the muffler housing and match the connection grooves. Then, by rotating the installation main body, it can be firmly connected to the muffler main body. The entire assembly process not only ensures the tightness and stability of the connection, but also significantly improves the convenience of assembly. Moreover, by using the threads on the outside of the connection column, the muffler can be easily connected to other devices. In the process of noise reduction, gas enters the muffler main body through the air inlet holes and then encounters the obstruction of the inner muffler plate. There are gaps between the inner muffler plate and the outer muffler plate, and these gaps form a complex labyrinth passage. In this labyrinth passage, the gas continuously changes its traveling direction and simultaneously undergoes multiple reflections and dispersions of sound waves, which not only ensures the smooth flow of the gas, but also significantly weakens the intensity and frequency of the noise through the continuous reflections and dispersions of the sound waves. Finally, the gas that has undergone noise reduction treatment in the labyrinth passage is discharged through the air outlet grooves on one side of the muffler main body, thus demonstrating an efficient noise control effect, making the noise reduction process both efficient and reliable, and not having an adverse impact on the operation of the device, completely avoiding the problem that the inner core of the traditional filter type muffler is prone to icing.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Reference Figures 1-4 , an embodiment provided by the present utility model is as follows:

[0031] A labyrinth muffler includes an installation main body 1 and a muffling main body 2. The installation main body 1 includes an air inlet hole 101, a connecting column 102, an installation shell 103, a plurality of through holes 104 and two clamping blocks 105. The upper end of the installation shell 103 is fixedly arranged at the lower end of the connecting column 102. The air inlet hole 101 is externally opened inside the connecting column 102 and the installation shell 103. A plurality of the through holes 104 are externally opened inside the installation shell 103. The two clamping blocks 105 are fixedly arranged on both sides inside the installation shell 103. The lower end of the installation main body 1 is rotatably arranged at the upper end of the muffling main body 2. A thread 3 is fixedly arranged outside the connecting column 102;

[0032] In actual use, by precisely docking the two clamping blocks 105 inside the installation shell 103 with the clamping strips 206 on the muffling outer shell 201, and precisely aligning with the connecting grooves 205, then rotating the installation main body 1 until it firmly engages with the muffling main body 2. Thus, the assembly process of the installation main body 1 and the muffling main body 2 not only ensures the tightness and stability of the connection, but also greatly improves the convenience of assembly. Then, by using the thread 3 arranged outside the connecting column 102, it is easy to fixedly connect the muffler with other devices, thereby providing an efficient and reliable solution for the noise control requirements in different application scenarios.

[0033] The muffling main body 2 includes a muffling outer shell 201, a plurality of air outlet grooves 202, a plurality of outer muffling plates 203, an inner muffling plate 204, two connecting grooves 205 and clamping strips 206. The lower end of the clamping strips 206 is fixedly arranged at the upper end of the muffling outer shell 201. The two connecting grooves 205 are externally opened on both sides of the clamping strips 206. The lower end of the inner muffling plate 204 is fixedly arranged at the lower end inside the muffling outer shell 201. The lower ends of the plurality of outer muffling plates 203 are all fixedly arranged at the lower end inside the muffling outer shell 201. The plurality of air outlet grooves 202 are externally opened on one side inside the muffling outer shell 201. The two clamping blocks 105 are slidably arranged outside the clamping strips 206;

[0034] During the silencing process, the gas is slowly introduced through the air inlet 101 of the installation body 1, and then enters the interior of the silencing body 2. The gas then encounters the inner silencing plate 204 inside the silencing body 2, and then shuttles through the maze passage constructed by the inner silencing plate 204 and multiple outer silencing plates 203, thereby forcing the gas to undergo countless turns and echoes, cleverly dispersing and weakening the originally turbulent sound waves, thereby achieving significant noise reduction effects. Finally, the gas that has undergone this meticulous silencing treatment leisurely passes through multiple air outlet slots 202 provided on one side of the silencing body 2, and is thereby discharged into the external environment. This not only achieves efficient noise control, but also has good adaptability and easy maintainability. It is suitable for a variety of aerodynamic equipment that requires strict noise control, greatly improves the operating environment, and protects personnel health and the surrounding environment from noise pollution.

[0035] Working principle: In actual application, when installing the labyrinth silencer, the two blocks 105 inside the mounting shell 103 are precisely aligned with the card strips 206 on the silencer outer shell 201, and the connection grooves 205 are precisely matched, so that the mounting body 1 and the silencer body 2 can be easily connected. Then, the mounting body 1 is rotated to make it firmly engage with the silencer body 2. The whole operation process not only ensures the tightness and stability of the connection, but also significantly improves the convenience of assembly. When the mounting body 1 and the silencer body 2 are tightly connected, the user can easily connect the silencer with other equipment by using the thread 3 on the outside of the connecting column 102, which not only simplifies the installation steps, but also enhances the adaptability of the silencer in different application scenarios. In order to improve the performance and reliability of the noise reduction system, the gas first passes through the air inlet 101 in the installation body 1. Once the gas enters the silencer body 2, it will be intercepted by the inner silencer plate 204. Then, the gas will pass through the carefully arranged gaps between the inner silencer plate 204 and the outer silencer plate 203. These gaps cleverly form an intricate maze channel, so that the gas undergoes countless direction changes and sound wave reflections during the movement. The maze channel not only ensures the smooth flow of gas, but also effectively weakens the intensity and frequency of noise through multiple sound wave reflections and dispersions, and finally the gas is discharged through the air outlet slot 202 opened on one side of the silencer body 2. At this time, the noise level of the gas is greatly reduced, achieving efficient noise control.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
