Silencer and silencing method thereof

Abstract

The invention discloses a silencer and aims to provide a silencer which is simple in structure and good in silencing effect. According to the key points of the technical scheme of the silencer, the silencer comprises an outer hood and a fixing seat placed on one side of the outer hood, an air inlet pipe is arranged on the outer hood, and an air outlet pipe is arranged on the fixing seat; a silencing device body is arranged in the outer hood and comprises a partition plate dividing the outer hood into a first cavity and a second cavity and a flow distributing hood placed at the air inlet end ofthe air outlet pipe; the first cavity communicates with the air inlet pipe, the air inlet direction of the air inlet pipe is tangent with the inner circumferential wall of the first cavity, and the second cavity communicates with the air outlet pipe; and the partition plate is provided with an air flow hole communicating with the first cavity and the second cavity, and the side wall of the flow distributing hood is provided with a plurality of flow distributing holes. The silencer is suitable for the technical field of air compressor parts.

Description

technical field [0001] The invention relates to the technical field of air compressor accessories, more specifically, it relates to a muffler and a muffler method thereof. Background technique [0002] The muffler is a noise reduction device installed in the intake and exhaust systems of aerodynamic equipment such as air compressors. [0003] In the invention patent application with the application number 201210245981.7, a muffler for an air compressor is disclosed, which realizes noise reduction through the setting of a rotatable partition and the airflow holes placed on the partition; Noise reduction; finally, further noise reduction is achieved through a cylindrical sponge; and it solves the problems of traditional mufflers with complex structure, difficult cleaning, and high quality, but this air compressor muffler still has the following problems: the partition needs to be rotatable The rotatable method requires external force to drive its rotation, and in order to inc...
