Abstract

The invention provides an exhaust silencer achieving air inflow adjustment. The exhaust silencer comprises an air inlet, first silencing nets, sound insulation boards, a small fan, second silencing nets, activated carbon, an air outlet, a shell and a dust cover. The exhaust silencer is characterized in that the sound insulation boards are arranged in the shell, the first silencing nets are arranged between the sound insulation boards, the small fan is arranged above the right side of the air inlet, the air inlet and the air outlet are connected with the shell, and the second silencing nets are arranged on the upper portion in the air outlet. The exhaust silencer is simple in structure, low in manufacturing cost and high in practicality; the air inflow can be adjusted through the small fan; air can be purified through the activated carbon, pollution is avoided, dust can be avoided through the dust cover, and cleanness is kept.

Description

technical field [0001] The invention relates to an exhaust muffler, in particular to an exhaust muffler with adjustable air intake, and belongs to the technical field of muffler manufacture. Background technique [0002] The muffler is a device that prevents sound transmission and allows airflow to pass through, and is an important measure to eliminate aerodynamic noise. The muffler is installed on the air flow channel of aerodynamic equipment (such as blower, air compressor, boiler exhaust, generator, water pump and other equipment with high exhaust noise) or in the intake and exhaust system to reduce noise. device. [0003] Today's mufflers are not fully functional, and some have complex structures and high costs. It is difficult to control the amount of air intake, and it will also pollute the air and affect the environment. Contents of the invention [0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide a...
