Environmental muffler

Abstract

The invention relates to an environmentally friendly silencer, which includes a silencer pipe, which is provided with a number of silencer holes, and a connecting pipe, one end of the connecting pipe is located outside the silencer pipe, the other end of the connecting pipe is located inside the silencer pipe, and the connecting pipe is located inside the silencer pipe. One end is rotatably connected with a rotating tube, the inside of the rotating tube is provided with fan blades, and the outer wall of the rotating tube is fixedly connected with a connecting plate; the inside of the silencer tube is provided with a baffle, and a number of chutes are provided on the baffle, and the chutes are radially arranged Evenly distributed on the baffle, piston heads are slidingly connected in the chute, long rods are fixedly connected to the piston heads, and a number of pins that can be inserted into the silencer holes are fixedly connected to the long rods; the connecting plate is away from the rotating tube A revolution plate is rotatably connected to the side of the piston, and piston rods are connected between several piston heads and the sides of the revolution plate. The two ends of the piston rods are respectively hinged on the piston head and the revolution plate. This solution prevents dust particles from adhering to the silencer holes of the silencer and improves the noise reduction effect.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to an environmental protection muffler. Background technique [0002] With the rapid development of the national economy, environmental noise has become one of the public hazards of contemporary human life. As the largest developing country in the world, my country's environmental protection and governance is one of my country's important national policies. Anti-vibration and noise reduction has become an important content of environmental protection measures. [0003] When exhaust gas is discharged from various factories, since the exhaust gas is discharged from the relevant devices of the factory, and when these devices are exhausted, there will be a certain amount of noise, which will cause the noise to spread outward and affect the quality of the environment. At present, in order to reduce the noise generated when the relevant devices discharge exhaust gas, a m...

AI Technical Summary

Problems solved by technology

[0004] Most of the traditional silencers are tubular, and there are several sound-absorbing holes on the pipe wall of the silencer. These sound-absorbing holes have a certain positive effect on reducing noise, but after long-term use, because the exhaust gas will be mixed with a lot of dust particles, These dust particles will adhere to the sound attenuation hole, thereby blocking the sound attenuation hole and reducing the noise reduction ability of the muffler
