Description

Technical Field

[0001] The utility model relates to the technical field of air compressors, in particular to an exhaust silencing device for an air storage tank of an air compressor. Background Art

[0002] The air compressor air tank is a pressure vessel used to store compressed air. It is mainly used for air storage and buffering. It also stabilizes the system pressure to avoid frequent loading and unloading of the air compressor and remove some liquid water. The air compressor air tank used in the mine is generally installed above the well, mainly for supplying equipment such as pneumatic picks, pneumatic drills, and rock drills at the underground mining face.

[0003] During the use of the air compressor air tank, compressed air will precipitate and accumulate water in the air compressor air tank, so exhaust, water drainage and pressure relief operations must be performed regularly. However, during the exhaust, water drainage and pressure relief operations, the pressure in the air compressor air tank will be much greater than the atmospheric pressure, thereby generating high-decibel noise, which seriously affects the work and rest of the surrounding personnel. In order to solve the shortcomings of the existing technology, we propose an air compressor air tank exhaust silencer. Utility Model Content
