Embodiment

[0018] like figure 1 As shown, the inclined baffle muffler has a scheme as follows: it includes a housing 20, one end of the housing 20 is connected to the intake pipe 10, the other end of the housing 20 is connected to the outlet pipe 40, and the housing 20 is provided with a first partition 21 and a second partition Plate 24, the first and second partitions divide the inside of the housing 20 into three chambers: upper, middle and lower chambers. The first partition 21 is arranged obliquely upward from the direction of the inlet pipe 10 to the outlet pipe 40, and the second partition 24 is formed by The direction from the air outlet pipe 40 to the air inlet pipe 10 is arranged obliquely upward, and a vertical air guide pipe 22 is also provided in the housing 20. The air guide pipe 22 is uniformly arranged in an array on the bottom surface of the housing 20, and the air guide pipe 22 is arranged in the upper and lower chambers. The indoor part is provided with ventilation hol...

Abstract

The invention discloses an oblique separating plate type muffler. According to the scheme, the oblique separating plate type muffler comprises a housing, wherein one end of the housing is connected to an air intake tube while the other end of the housing is connected to an air exhausting tube; a first separating plate and a second separating plate are arranged in the housing and can divide the inner part of the housing into an upper chamber, an intermediate chamber and a lower chamber; the first separating plate is obliquely upwards arranged from the air intake tube to the air exhausting tube; the second separating plate is obliquely upwards arranged from the air exhausting tube to the air intake tube; vertical air conduits are arranged in the housing and are uniformly distributed in a form of an array on the bottom surface of the housing; ventilating holes are formed in parts, in the upper chamber and the lower chamber, of each air conduit. The oblique separating plate type muffler enables mutual overlapping of sound wave, thus achieving the purpose of removing noise.

Description

technical field [0001] The invention relates to an inclined partition muffler. Background technique [0002] Noise is one of the three major sources of pollution, and the noise radiated by motor vehicles accounts for about 75% of the noise energy in the entire environment. Therefore, reducing the noise of motor vehicles is the most fundamental way to reduce urban environmental noise. Exhaust noise is the most important noise source of automobiles and engines, which is usually 10dB(A)~15dB(A) higher than the overall engine noise (except exhaust noise). The control of engine exhaust noise can be divided into two aspects: on the one hand, measures can be taken against the noise source itself, which needs to start with the analysis of the noise source mechanism and take corresponding countermeasures; on the other hand, measures include the use of exhaust mufflers and Controls mechanical noise from the engine exhaust manifold. Among them, the most effective and simplest is to ...
