Problems solved by technology

[0004] However, although the existing muffler of the air duct can solve the noise problem to a certain extent, the size of the muffler cannot be too large in some narrow areas, and an ultra-long muffler is needed to solve the noise problem. The length of this muffler can reach Existing ultra-long mufflers that are more than ten meters long are basically produced and installed on site. This approach not only increases the construction cost, but also increases the time for installation, which is time-consuming and laborious. Moreover, the quality of the on-site processed mufflers cannot be obtained. Assure

Embodiment 1

[0032] Such as Figure 1-Figure 9 As shown, the present invention provides a hoisting type muffler for air ducts that can be assembled, including: a first sub-muffler 1 , a second sub-muffler 2 and a hoisting structure 3 . Among them, both the first sub-muffler 1 and the second sub-muffler 2 are rectangular tubular structures, the external dimensions of the second sub-muffler 2 match the external dimensions of the first sub-muffler 1, and one end of the second sub-muffler 2 is provided with an air nozzle twenty one. The quantity of the first sub-muffler 1 is multiple, and the plurality of first sub-mufflers 1 are connected to each other, and the quantity of the second sub-muffler 2 is two, and the two second sub-mufflers 2 are respectively arranged on a plurality of first sub-mufflers 1 mutually. After connecting the two ends, the end of the second sub-muffler 2 provided with the air nozzle 21 is set on the side away from the first sub-muffler 1 . Both the first sub-muffler ...

Embodiment 2

[0043] The following introduces the manufacturing method of the assembling-mounted air duct pipe muffler of the present invention:

[0044] First, carry out on-site measurement and measurement to determine the exact position of the muffler and the position of the air nozzle connected to the air duct. The muffler is segmented according to the length of the muffler.

[0045] Process the muffler sheet 11 of the rectangular tubular structure according to the length of the section, and fix a connecting flange 12 at both ends of the muffler sheet 11 of the rectangular tubular structure to make the first sub-muffler 1, which is fixedly connected at one end of the muffler sheet 11 Flange 12, the other end fixes tuyere 21 to make second sub-muffler 2, and the outer wall of first sub-muffler 1 and second sub-muffler 2 is installed reinforcing steel frame 13.

[0046] Process the first hoisting frame 31, the second hoisting frame 32 and the third hoisting frame 33, fix the muffler sheet...

Embodiment 3

[0048] The following introduces the installation method of the assembled hoisting air duct pipe muffler of the present invention:

[0049] Fix the first section of the second sub-muffler 2 on the wall 4 at the top of the air duct through the third hanging frame 33, and then fix the first section of the second sub-muffler 1 on the top wall of the air duct through the third hanging frame 33 4. Place a 50mm thick silicon glass rubber pad between the two sub-mufflers, connect the connecting flanges 12 of the two sub-mufflers with bolts, and seal the gap with sealant.

[0050] Repeat the above steps until the hoisting of all the first sub-mufflers 1 and the second sub-mufflers 2 is completed, wherein multiple first sub-mufflers 1 are connected to each other, and two second sub-mufflers 2 are respectively arranged on multiple first sub-mufflers 1 The two ends connected to each other, and the end with the air nozzle 21 is set on the side away from the first sub-muffler 1 .

Abstract

The invention discloses a hoisting type air duct pipeline silencer capable of being assembled. The hoisting type air duct pipeline silencer capable of being assembled comprises first sub-silencers, second sub-silencers and a hoisting structure, wherein the first sub-silencers and the second sub-silencers are each of a rectangular tubular structure, and tuyeres are arranged at one ends of the second sub-silencers; the plurality of first sub-silencers are arranged, the plurality of first sub-silencers are connected with one another, the two second sub-silencers are arranged, the two second sub-silencers are arranged at the two ends after the plurality of first sub-silencers are connected with one another, and the ends, provided with the tuyeres, of the second sub-silencers are arranged on the sides away from the first sub-silencers; and the first sub-silencers and the second sub-silencers are fixedly connected with the hoisting structure, and the hoisting structure is fixedly arranged on a wall body at the top of the air duct pipeline. According to the hoisting type air duct pipeline silencer, the ultra-long silencer is divided into the plurality of first sub-silencers and the second sub-silencers, so that installation is convenient, the installation time is remarkably shortened, and time and labor are saved.

Description

technical field [0001] The invention relates to the technical field of air duct noise reduction, in particular to a hoisting type air duct pipe muffler which can be assembled. Background technique [0002] At present, in the mechanical and electrical installation and construction, in order to reduce the huge noise when the fan is running, a muffler is often installed in the air duct. [0003] Patent CN110848497A discloses a noise reduction and noise reduction device used in air ducts. The noise reduction and noise reduction device includes a soft joint and a muffler. Flange pieces are installed at both ends of the soft joint and the muffler; The pipe is cut and removed, and the flange piece is installed on the nozzle by welding. The flange piece at one end of the soft joint is connected with the flange piece at the end of the pipe on one side, and the flange piece at the other end of the soft joint is connected with the flange at the end of the muffler. The flange piece at ...
