Winding type silencer

The invention provides a winding type silencer. The silencer comprises at least one group of silencer main bodies, the silencer body comprises a first end cover, a second end cover, a shell, a sound insulation cavity and a framework net. First annular grooves and second annular grooves are respectively formed in the side walls of the first end cover and the second end cover; the shell is a cylindrical hollow shell; the two ends of the shell are fixedly embedded into the first annular grooves correspondingly, the framework net is arranged to be a cylindrical hollow framework net, the two ends of the framework net are embedded into the second annular grooves correspondingly, the sound insulation cavity is formed by a gap between the framework net and the shell, and the sound insulation cavity is filled with a sound insulation assembly. According to the winding type silencer obtained through the design, when the winding type silencer is used, air flow enters the framework net and then isabsorbed through the soun
