Description

Technical Field

[0001] This utility model relates to the field of silencer technology, specifically a square modular silencer. Background Technology

[0002] A silencer is a noise reduction device used in airflow ducts that simultaneously transmit noise. It utilizes pipes with sound-absorbing linings, bends, or pipes with sudden changes in cross-sectional area or other discontinuous acoustic impedance to attenuate or reflect noise back into the duct. A square modular silencer is a type of noise reduction device, characterized by its modular design and convenient on-site assembly. This type of silencer typically consists of multiple noise-reducing components, each of which can be independently installed and disassembled for easy maintenance and replacement. While efficient noise reduction requires silencers, existing silencers still have the following shortcomings:

[0003] For example, the utility model with announcement number CN206134243U discloses an array-type muffler. The purpose of this utility model is to improve the conventional flat-shaped flow guide cap and reduce the resistance loss of the flow guide cap. However, similar to the prior art of the above application, when existing mufflers are used, most mufflers are fixed and installed by bolts, which makes the disassembly and assembly process time-consuming and labor-intensive, and increases the intensity of manual labor, resulting in a decrease in the practicality and efficiency of the muffler.

[0004] Therefore, in view of this, we studied and improved the existing structure and its shortcomings, and proposed a square modular silencer. Utility Model Content

[0005] The purpose of this invention is to provide a square modular silencer to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a square modular silencer, comprising a main frame and a silencer assembly. The main frame has an internal mounting groove, and the silencer assembly is provided inside the main frame. The silencer assembly includes a protective shell, a docking groove, a mounting slider, fiberglass cloth, centrifugal glass wool, and an air guide plate. The protective shell has a docking groove on the right side inside, and a mounting slider is added to the upper part of the outer side of the protective shell. Fiberglass cloth is added inside the protective shell, and centrifugal glass wool is added inside the fiberglass cloth. An air guide plate is added inside the centrifugal glass wool. Stabilizing components are provided on both sides of the outer side of the main frame.

[0007] Furthermore, the outer side of the mounting slider is horizontally distributed with the outer side of the protective shell, and the mounting slider is fixedly connected to the protective shell by bolts.

[0008] Furthermore, the external dimensions of the mounting slider are adapted to the internal dimensions of the mounting groove, and the mounting slider is slidably connected to the main frame through the mounting groove.

[0009] Furthermore, the internal dimensions of the centrifugal glass wool are adapted to the external dimensions of the air guide plate, and the air guide plate and the centrifugal glass wool are fixedly connected by bolts.

[0010] Furthermore, the stabilizing component includes a mounting base, a mounting plate, and threaded mounting grooves. The mounting base is externally mounted with a mounting plate, and the mounting plate has threaded mounting grooves on both sides inside.

[0011] Furthermore, the stabilizing component also includes a threaded rotating rod, an auxiliary rotating handle, and a receiving block. The threaded rotating rod is connected inside the threaded mounting groove, and the auxiliary rotating handle is installed at the upper end of the threaded rotating rod. The receiving block is connected at the lower end of the threaded rotating rod.

[0012] Furthermore, the internal dimensions of the threaded mounting groove are adapted to the external dimensions of the threaded rotating rod, and the threaded rotating rod is rotatably connected to the mounting plate through the threaded mounting groove.

[0013] Furthermore, the number of the receiving blocks is set to four, and two receiving blocks form a group, and each group of receiving blocks is symmetrically arranged on both sides of the outside of the main frame with respect to the front central axis of the main frame.

[0014] This utility model provides a square modular silencer, which has the following advantages:

[0015] 1. This utility model, through the setting of the silencing component, enables the installation slider to be fixedly installed on the upper end and left side of the outer shell of the square modular silencer by fastening bolts. The installation slider, in conjunction with the installation groove, slides the protective shell into the main frame. The fiberglass cloth is then fixedly installed inside the protective shell. The fiberglass cloth enhances the structural strength and silencing effect, and the centrifugal glass wool added inside the fiberglass cloth further absorbs noise and improves the silencing effect. At the same time, the air guide plate installed inside the centrifugal glass wool helps to guide the airflow and reduce airflow turbulence, further improving the silencing effect of the square modular silencer and increasing the overall practicality and efficiency of the square modular silencer.

[0016] 2. This utility model, through the setting of stabilizing components, enables the mounting plate to be fixedly installed on both sides of the main frame by fastening bolts and mounting base when the square modular silencer is in use. The threaded mounting groove is used to rotate the threaded rod into the inside of the mounting plate, and the auxiliary throttle handle increases the convenience of the threaded rod rotation process. As the threaded rod rotates, the receiving block moves down, and the contact between the receiving block and the ground increases the stability of the main frame during use, thereby avoiding positional displacement of the main frame when subjected to external forces and improving the overall efficiency of the square modular silencer.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] like Figure 1 , Figure 2 and Figure 3As shown, a square modular silencer includes a main frame 1 and a silencer assembly 3. The main frame 1 has an internal mounting groove 2, and the silencer assembly 3 is housed inside the main frame 1. The silencer assembly 3 includes a protective shell 301, a docking groove 302, a mounting slider 303, fiberglass cloth 304, centrifugal glass wool 305, and an air guide plate 306. The protective shell 301 has a docking groove 302 on its right side, and a mounting slider 303 is added to the upper part of the protective shell 301. Furthermore, fiberglass cloth 304 is added inside the protective shell 301. The fiberglass cloth 304 is reinforced with centrifugal glass wool 305, and a guide plate 306 is added inside the centrifugal glass wool 305. The outer side of the mounting slider 303 is horizontally distributed with the outer side of the protective shell 301, and the mounting slider 303 is fixedly connected to the protective shell 301 by bolts. The external dimensions of the mounting slider 303 are adapted to the internal dimensions of the mounting groove 2, and the mounting slider 303 is slidably connected to the main frame 1 through the mounting groove 2. The internal dimensions of the centrifugal glass wool 305 are similar to the external dimensions of the guide plate 306. The air guide plate 306 and centrifugal glass wool 305 are fixedly connected by bolts. The mounting slider 303 is fixedly installed on the upper part and left side of the outer side of the protective shell 301 by tightening the bolts. The external dimensions of the mounting slider 303 are compatible with the internal dimensions of the mounting groove 2 opened inside the main frame 1. Thus, the protective shell 301 is slidably installed into the main frame 1 by the mounting slider 303 and the mounting groove 2. This allows multiple protective shells 301 to be installed into the main frame 1 in sequence, avoiding bolt installation and increasing the convenience of the silencer installation process. The fiberglass cloth 304 is fixedly installed inside the protective shell 301. The fiberglass cloth 304 enhances the structural strength and sound absorption effect. The centrifugal glass wool 305 added inside the fiberglass cloth 304 further absorbs noise and improves the sound absorption effect. At the same time, the air guide plate 306 installed inside the centrifugal glass wool 305 helps to guide the airflow and reduce airflow turbulence, further improving the sound absorption effect of the square modular silencer and increasing the overall practicality and efficiency of the square modular silencer.

[0024] like Figure 1 , Figure 2 and Figure 4As shown, stabilizing components 4 are provided on both sides of the main frame 1. The stabilizing components 4 include a mounting base 401, a mounting plate 402, and threaded mounting grooves 403. The mounting plate 402 is mounted on the outside of the mounting base 401, and threaded mounting grooves 403 are provided on both sides of the mounting plate 402. The stabilizing components 4 also include a threaded rotating rod 404, an auxiliary handle 405, and receiving blocks 406. The threaded rotating rod 404 is connected inside the threaded mounting grooves 403, and the auxiliary handle 405 is mounted on the upper end of the threaded rotating rod 404. The receiving blocks 406 are connected to the lower end of the threaded rotating rod 404. The internal dimensions of the threaded mounting grooves 403 are adapted to the external dimensions of the threaded rotating rod 404, and the threaded rotating rod 404 is rotatably connected to the mounting plate 402 through the threaded mounting grooves 403. Four receiving blocks 406 are provided, with two receiving blocks 406... Six blocks are arranged in a group, and each group of receiving blocks 406 is symmetrically arranged on both sides of the main frame 1 with respect to the central axis of the front of the main frame 1. The mounting plate 402 is fixedly installed on both sides of the main frame 1 with fastening bolts and mounting base 401. The internal dimensions of the threaded mounting groove 403 opened inside the mounting plate 402 match the external dimensions of the threaded rotating rod 404. Thus, the threaded rotating rod 404 is rotated and installed into the mounting plate 402 through the threaded mounting groove 403. The auxiliary handle 405 is used to increase the convenience of rotating the threaded rotating rod 404. As the threaded rotating rod 404 rotates, the receiving blocks 406 move down. The contact between the receiving blocks 406 and the ground increases the stability of the main frame 1 during use, thereby avoiding the positional displacement of the main frame 1 when subjected to external forces and improving the overall efficiency of the square modular silencer.

[0025] In summary, when using this square modular silencer, the mounting slider 303 is first fixed to the upper part and left side of the protective shell 301 using fastening bolts. The protective shell 301 is then slidably installed into the main frame 1 using the mounting slider 303 and mounting groove 2. This allows multiple protective shells 301 to be installed into the main frame 1 sequentially. The fiberglass cloth 304 inside the protective shell 301 enhances the structural strength and sound absorption effect, and the centrifugal glass wool 305 added inside the fiberglass cloth 304 further absorbs noise. Simultaneously, the air guide plate 306 installed inside the centrifugal glass wool 305 helps guide airflow and reduce airflow turbulence. To further enhance the noise reduction effect of the square modular silencer, the mounting plate 402 is then fixed to the outside of the main frame 1 using fastening bolts and mounting base 401. The threaded rod 404 is then rotated into the mounting plate 402 using threaded mounting groove 403. An auxiliary handle 405 is used to increase the ease of rotation of the threaded rod 404. As the threaded rod 404 rotates, the receiving block 406 moves downward. The contact between the receiving block 406 and the ground increases the stability of the main frame 1 during use, thereby preventing the main frame 1 from shifting its position when subjected to external forces and improving the overall efficiency of the square modular silencer.
