Description

TECHNICAL FIELD

[0001] The utility model relates to the field of large air volume and multi-exhaust point pneumatic equipment, in particular to a silencer applied to large exhaust equipment. BACKGROUND

[0002] When the pneumatic machine works, the mechanical part of the pneumatic actuator needs to be lubricated. Due to sealing or other reasons, part of the lubricating oil may enter the circulating air passage of compressed air in different ways or channels. In addition, in order to ensure the normal work of the pneumatic element or prolong its service life, an oil atomizer is specially installed in the air supply system of the pneumatic machine. The lubricating oil is atomized and then expands, works and discharges with the compressed air. Therefore, when the pneumatic machine works, exhaust noise is generally generated, and part of the lubricating oil mist is removed with the exhaust, causing noise and oil mist pollution to the working environment. In order to reduce noise pollution, a silencer is generally installed at the exhaust port. However, there is no simple and effective method to solve the oil mist pollution.
