An assembled air shaft muffler

Abstract

The invention discloses an assembled air well muffler, comprising: an installation frame and a muffler installed in the installation frame; the installation frame includes: a first installation frame and a second installation frame; wherein the number of the first installation frame is large A plurality of first mounting racks are connected to each other, the number of second mounting racks is two, and the two second mounting racks are respectively arranged at both ends of the plurality of first mounting racks after they are connected to each other; the first mounting rack and the second mounting rack The installation frames are all U-shaped structures, and mufflers are installed in the U-shaped structures of the first installation frame and the second installation frame; both the first installation frame and the second installation frame are installed on the wall in the air shaft. In the present invention, the installation frame is divided into a plurality of first installation frames and two second installation frames, which are installed on the wall in the air shaft in the form of sections. The installation method in sections greatly reduces the difficulty of installation and saves Installation time, saving time and effort.

Description

technical field [0001] The invention relates to the technical field of air well mufflers, in particular to an assembled air well muffler. Background technique [0002] At present, in the electromechanical installation and construction, in order to reduce the huge noise when the fan is running and reduce noise pollution, mufflers are often installed in the exhaust air shaft or the air intake air shaft of the building. [0003] Patent CN207959821U discloses a muffler structure for vertical air shafts, which relates to the field of air shaft muffling. The device includes an annular groove, a hanger rod and several mufflers arranged in the wall of the air shaft. The annular groove includes upper and lower intervals. The first annular groove and the second annular groove are provided, the suspension rod includes a plurality of first suspension rods and a plurality of second suspension rods, and both ends of the first suspension rods are detachably arranged in the first annular gr...

Problems solved by technology

[0004] However, due to the high installation height of the existing air shaft muffler mounting frame, and the existing air shaft muffler mounting frame is only vertically detachable and installed, but the horizontal direction is still installed as a whole structure, and it is extremely difficult to install when the horizontal distance is too long. Inconvenient, not only increases the construction cost, but also increases the installation time, time-consuming and labor-intensive, and it is easy to cause damage to the muffler, which is not conducive to the installation of the wind shaft muffler
