Silencing sheet of resistive silencer

Abstract

The invention discloses a silencing sheet of a resistive silencer. The silencing sheet comprises a silencing sheet body and an installation box, an isolation box is arranged on the outer side of the silencing sheet body, a plurality of through holes are formed in the two sides of the isolation box, an installation frame is fixed to the outer side of the isolation box, and a plurality of limiting holes are formed in the top of the installation frame. Limiting rods are movably inserted into the limiting holes, sliding grooves are formed in the inner top and the inner bottom of the installation box correspondingly, a through opening is formed in a box body of the installation box, a rotating rod is rotatably connected into the through opening, a plurality of cams are fixed to the outer side of the rotating rod, and the bottom of a connecting plate is fixed to the tops of the limiting rods. The silencing sheet is convenient to disassemble and assemble, easy to operate, convenient to overhaul, beneficial to improving the working efficiency, capable of being protected to a certain extent, beneficial to prolonging the service life of the silencing sheets and meanwhile beneficial to improving the silencing effect, and has good practical significance.

Description

technical field [0001] The invention relates to the technical field of muffler equipment, in particular to a muffler sheet of a resistive muffler. Background technique [0002] The resistive muffler is a muffler that uses sound waves to propagate in porous sound-absorbing materials or sound-absorbing structures, and converts sound energy into heat energy due to friction and dissipates it, so that the noise propagating along the pipeline is attenuated with distance, thereby achieving the purpose of muffler , The muffler is mainly composed of a box and a muffler, and the muffler mainly plays the role of muffler through the muffler. [0003] However, the existing mufflers are often directly fixed on the inner wall of the box body. When maintenance is required, it is not easy to disassemble and assemble, which reduces the efficiency of maintenance work. Therefore, we propose a muffler for resistive mufflers. Contents of the invention [0004] The object of the present inventi...
