AI Technical Summary
Technical Problem
Existing pneumatic workpieces generate significant exhaust noise during use, and conventional silencers have limited noise reduction effects, impacting worker health.
Method used
An additional section of tubing is added to the muffler, and breathable cotton is filled inside the tubing. The muffler is installed at the very front of the tubing. The breathable cotton reduces the compressed air velocity, while the sealing gasket improves the sealing performance at the connection.
Benefits of technology
The compressed air flow rate is reduced, the exhaust noise is reduced by 50%, the sealing performance at the connection is improved, and it is easy to replace the breathable cotton.

Abstract
The utility model discloses an exhaust silencing pipe, which relates to the technical field of pneumatics and comprises a pipe cavity main body, the inner wall of the pipe cavity main body is in threaded connection with a silencer body, and the inner wall of the silencer body is fixedly connected with first breathable cotton used for absorbing exhaust noise energy. The pipe cavity body is filled with second breathable cotton used for reducing exhaust noise. According to the utility model, a section of pipe cavity is additionally arranged on the original silencer, the ventilation cotton is filled in the pipe cavity, and the silencer is arranged at the foremost end of the pipe cavity, so that when compressed air passes through the pipe cavity, the flow rate of the compressed air can be reduced under the action of the ventilation cotton, and the flow rate of the compressed air can be reduced when the compressed air passes through the original silencer. And the exhaust noise can be reduced by 50%.
