furthermore, the fan and the silencer shell can be fixed through the fan rubber pad, and vibration generated by operation of the fan is reduced.
Furthermore, the shutter is arranged on the shell of the auxiliary silencer, so that the exhaust requirement is met, and the opening of the silencer can be shielded to prevent foreign matters from entering.
Furthermore, the main silencer shell and the auxiliary silencer shell can be manufactured into modules with the silencing function, the silencer shell is divided into an outer plate and a sound absorbing material is filled between the outer plate and the inner plate; the gap between the outer plates in the shape of a cuboid is blocked by a perforated plate; the inner plate adopts a perforated plate, a cavity is reserved in the middle, and the shape and the size of the cavity are consistent with those of the inner noise eliminator.
Owing to take above technical scheme, the utility model has the advantages of it is following: 1. the silencer and the fan are combined into a whole, the traditional step of firstly installing the fan and then installing the silencer is changed, the engineering efficiency is improved, and the integral attractiveness is improved; 2. the silencing component in the silencer is of a cubic structure, the traditional sheet type is changed, and the silencing performance is obviously improved. 3. The muffler structure is manufactured in a modularized mode, is simple and convenient to install, and is convenient to disassemble and replace.
The utility model is suitable for a noise reduction volume requires high and frequently installs, dismantles the high noise occasion, not only can effectively eliminate the noise of little volume noise source, can regard as the important part in sound insulation cover or sound insulation room moreover.
