Abstract

The invention discloses a pressure reduction silencer. The pressure reduction silencer comprises a shell, an air inlet, an air outlet and a device door; a lantern ring is arranged on the outer side ofthe shell in a sleeving mode; a connecting rod is fixed at the bottom of the lantern ring; the air inlet is fixed at the upper corner of the shell; a slow flow box is internally provided with a connecting shaft; a fixed plate is fixed on the side of the connecting shaft; a partition plate is arranged below the connecting shaft; the bottom of the slow flow box is connected with one end of a silencing tube; a connecting tube is arranged on the side of the silencing tube; the air outlet is fixed at the lower corner of the shell; a first silencing layer is adhered to the inner wall of the shell;a second silencing layer is arranged on the side of the first silencing layer; and a third silencing layer is applied on the outer wall of the shell. According to the pressure reduction silencer, a mounting mode of the silencer can be changed according to mounting requirements, and the noise reduction amount of the silencer can be improved through a plurality of different silencing materials, so that the noise can be prevented from being transmitted to outside before being removed completely in a device.

Description

technical field [0001] The invention relates to the technical field of mufflers, in particular to a pressure-reducing muffler. Background technique [0002] The muffler is a device that reduces or prevents the sound from spreading but allows airflow to pass through. The muffler is widely used in the fields of electric power, petroleum, chemical industry, food, etc., and the muffler has excellent characteristics such as small size, light weight, and simple structure. However, existing The decompression muffler has the following disadvantages during use: [0003] The installation of the muffler is not flexible enough. The sound-absorbing material in the existing muffler on the market is not good enough for noise elimination, which causes the noise to spread out if the noise is not eliminated thoroughly in the device. To solve the above problems, it is urgent to reduce the noise in the original Innovative design based on pressure silencer. Contents of the invention [0004]...
