Embodiment

[0018] Such as figure 1 As shown, the sleeve type 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 a ventilation ho...

Abstract

The invention discloses a casing type silencer. According to the scheme, the casing type silencer comprises a shell; one end of the shell is connected with an air inlet pipe; the other end of the shell is connected with an air outlet pipe; a first partition board and a second partition board are arranged inside the shell and divide the interior of the shell into an upper cavity, a middle cavity and a lower cavity; the first partition board is arranged aslant upwards from the air inlet pipe to the air outlet pipe; the second partition board is arranged aslant upwards from the air outlet pipe to the air inlet pipe; vertical air guide pipes are arranged inside the shell and evenly distributed on the bottom face of the shell in an array; ventilation holes are formed in the parts, inside the upper and lower cavities, of the air guide pipes; a casing pipe is arranged on the part, inside the hollow cavity, of the air guide pipes; an end socket is arranged in the middle of the part, inside the casing pipe, of the air guide pipes; ventilation holes are formed in the part, inside the casing pipe, of the air guide pipes. The casing type silencer enables sound waves to be overlapped so as to achieve the purpose of eliminating noise.

Description

technical field [0001] The invention relates to a sleeve type 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 use the ...
