Abstract

The invention discloses a silencing device, and belongs to the technical field of silencers. The invention aims to process and reduce noise generated by an engine and reduce noise pollution. According to the technical scheme, the silencing device comprises an outer shell, and a first partition plate, a second partition plate, a third partition plate, a fourth partition plate and a fifth partition plate are sequentially arranged between one end and the other end in the outer shell to divide the interior of the outer shell into a first silencing chamber, a second silencing chamber, a third silencing chamber, a fourth silencing chamber, a fifth silencing chamber and a sixth silencing chamber; an air inlet is formed in the outer shell of the third anechoic chamber, and an air outlet is formed in the outer shell of the sixth anechoic chamber.

Description

technical field [0001] The invention belongs to the technical field of noise reduction devices, and relates to a noise reduction device. Background technique [0002] An engine is a machine that can convert other forms of energy into mechanical energy, and is a mechanical device that generates power. The sound intensity produced by the engine when it is working is very loud, and the sound directly transmitted from the engine body and its main accessories to the space belongs to the engine noise. Noise is a by-product of industrial society, and together with air pollution and water pollution, it is considered to be the three major public hazards in the world today. Noise pollution is formed when noise has adverse effects on people and the surrounding environment. Compared with the other two public hazards, noise has the widest influence, the most direct feeling, and the most people's feedback. [0003] In the course of realizing the present invention, the inventor finds th...
