Description

Technical Field

[0001] This utility model relates to the field of silencer technology, specifically to a silencer with a detachable silencer plate. Background Technology

[0002] Plate silencers are a type of resistive silencer. Silencers can block the propagation of sound waves while allowing airflow, making them an effective tool for noise control.

[0003] A typical plate-type silencer has a structure in which sound-absorbing material or structures are laid on the left and right sides, and a sound-absorbing plate is inserted in the middle. When the silencer is working, the sound waves propagate inside the silencer, and the walls absorb the noise. The sound pressure disappears as the propagation distance increases. However, the number of existing sound-absorbing plates and the spacing between the plates will affect the sound insulation effect of the silencer, and the position cannot be adjusted for adaptation, which reduces the practicality of the sound-absorbing plate installation.

[0004] Therefore, it is necessary to redesign and modify the sound-absorbing plates to effectively prevent the number of sound-absorbing plates and the spacing between them from affecting the sound insulation effect of the muffler, and to address the issue of not being able to adjust their positions for adaptation. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] like Figures 1 to 4 As shown, the present invention provides a muffler with a detachable muffler plate, comprising:

[0023] A steel structure frame 1, a steel plate 2 is fixedly installed on the inner side of the steel structure frame 1, a special base plate 3 is fixedly installed on the bottom of the inner side of the steel structure frame 1, and an assembly mechanism 4 is opened on the top of the special base plate 3.

[0024] The assembly mechanism 4 includes a T-slot 41, a T-block 42, a bolt 43, a sound-absorbing plate 44, and a frame 45. The top of the special base plate 3 is provided with a T-slot 41. The T-block 42 is slidably connected inside the T-slot 41. The top of the T-block 42 is movably connected to the bolt 43 by a thread. The top of the bolt 43 is movably connected to the sound-absorbing plate 44 by a bearing seat. The top and bottom of the front end of the inner wall of the steel plate 2 are fixedly connected to the frame 45. The top of the inner cavity of the frame 45 is horizontally fixedly connected to the balancing mechanism 5.

[0025] refer to Figure 3 The balancing mechanism 5 includes a crossbar 51, a sleeve block 52, a fixed rod 53, and a spindle sleeve 54. The crossbar 51 is horizontally fixedly connected to the top of the inner cavity of the frame 45. The sleeve block 52 is slidably sleeved on the left and right sides of the surface of the crossbar 51. The front end of the sleeve block 52 passes through the front end of the frame 45 and contacts the surface of the sound-absorbing plate 44. The fixed rod 53 is horizontally fixedly connected to the bottom of the inner cavity of the frame 45. The spindle sleeve 54 is slidably sleeved on the left and right sides of the surface of the fixed rod 53. The end of the spindle sleeve 54 away from the fixed rod 53 is fixedly connected to the bottom of the sleeve block 52.

[0026] As a technical optimization of this utility model, by setting the balancing mechanism 5, the sleeve block 52 can move stably with the sound-absorbing plate 44. The sleeve block 52 moves along the surface of the crossbar 51 and synchronously drives the shaft sleeve 54 to move along the fixed rod 53, so that the rear part of the sound-absorbing plate 44 is supported and balanced.

[0027] refer to Figure 3 Springs 6 are fitted onto the left and right sides of the surface of the fixing rod 53. The left and right sides of the springs 6 are fixedly connected to the right side of the shaft sleeve 54 and the surface of the fixing rod 53, respectively.

[0028] As a technical optimization of this utility model, the spring 6 can assist the shaft sleeve 54 in working and at the same time play a role in reset and buffering, so as to prevent the shaft sleeve 54 from failing to reset after moving, which would cause the machine to stop working continuously.

[0029] refer to Figure 3 Rubber sleeves 7 are fixedly fitted on the left and right sides of the surface of the crossbar 51, and the rubber sleeves 7 are used in conjunction with the crossbar 51.

[0030] As a technical optimization of this utility model, the rubber sleeve 7 can assist the sleeve block 52 in its work and also play a protective role, avoiding the phenomenon of collision and wear caused by the sleeve blocks 52 contacting each other.

[0031] refer to Figure 1 Each of the four corners of the top of the steel structure frame 1 is fixedly connected with a lifting ring 8, which is used in conjunction with the steel structure frame 1.

[0032] As a technical optimization of this utility model, the setting of the lifting ring 8 can assist the steel structure frame 1 in its work and play a role in hoisting, thus avoiding the inconvenience of transporting and assembling the steel structure frame 1 as a whole.

[0033] refer to Figure 4 The T-block 42 has a threaded groove in its inner cavity and is used in conjunction with the bolt 43.

[0034] As a technical optimization of this utility model, the T-block 42 can assist the bolt 43 in its work, thus avoiding the inability to assemble and disassemble the bolt 43 and the T-block 42.

[0035] The working principle and usage process of this utility model are as follows: First, install the steel plate 2 and the special base plate 3 onto the steel structure frame 1. Then, according to the site conditions, install the T-shaped block 42 inside the T-slot 41. Next, move the sound-absorbing plate 44 as a whole inside the steel structure frame 1 so that the bolt 43 aligns with the top of the T-slot 41. The back end of the sound-absorbing plate 44 is inserted into the inner side of the sleeve block 52. Then, manually rotate the bolt 43 clockwise to assemble and fix it to the T-shaped block 42. After adjusting the spacing between the sound-absorbing plates 44 to a suitable distance, the movement of the sound-absorbing plate 44 drives the bolt 43... The T-block 42 moves stably along the T-slot 41, while the silencing plate 44 moves synchronously, driving the sleeve block 52 to move stably along the surface of the crossbar 51. The movement of the sleeve block 52 drives the shaft sleeve 54 to move accordingly. The shaft sleeve 54 moves smoothly along the surface of the fixing rod 53 and compresses the spring 6. The sleeve block 52 helps to fix the silencing plate 44 to maintain balance and stability during its movement. Finally, by testing the noise level with a professional sound level meter at a specific location, the silencing plate 44 is repeatedly adjusted to ensure that the noise level meets the national industrial enterprise noise emission standards.

[0036] In summary, this muffler with detachable sound-absorbing plates, through the coordinated use of a steel structure frame 1, steel plate 2, special base plate 3, assembly mechanism 4, T-slot 41, T-block 42, bolt 43, sound-absorbing plate 44, frame 45, and balancing mechanism 5, solves the problem that the number of sound-absorbing plates and the spacing between them affect the sound insulation effect of the muffler, and that the position cannot be adjusted for adaptation.
