Abstract
The utility model belongs to the technical field of silencers and discloses an environment-friendly silencer of a heavy-duty vehicle. The environment-friendly silencer is mainly and technically characterized by comprising a shell with a gas inlet and a gas outlet, wherein the wall of the shell consists of an outer-layer shell wall and an inner-layer shell wall; and an asbestos fiber noise-reducing and heat-insulating layer is arranged between the outer-layer shell wall and the inner-layer shell wall. The environment-friendly silencer provided by the utility model has the advantages that since the wall of the shell consists of the outer-layer shell wall and the inner-layer shell wall, and the asbestos fiber noise-reducing and heat-insulating layer is arranged between the outer-layer shell wall and the inner-layer shell wall, the double-wall silencer is good in silencing effect, less in environmental pollution and low in noise compared with a single-wall silencer.
Description
Technical field
The utility model belongs to the silencing apparatus technical field, relates in particular to a kind of heavy goods vehicles environment protection type silencing apparatus.
Background technique
The tail gas that motor car engine produces is discharged in the atmosphere through outlet pipe, baffler.Current its structure comprises the housing that has suction port and air outlet at loader, excavator, road roller, the silencing apparatus that heavily uses on the heavy goods vehicles such as card, and the shell wall of housing is an individual layer; The housing intracavity structure is simple; Erasure effect is not fine, and environmental pollution is big, and noise is big.
The model utility content
The utility model technical problem to be solved just provides a kind of good muffling effect, and environmental pollution is little, the heavy goods vehicles environment protection type silencing apparatus that noise is little.
For solving the problems of the technologies described above; The technological scheme that the utility model adopts is: comprise the housing that has suction port and air outlet; The shell wall of said housing is made up of outer shell wall and internal layer shell wall, is provided with asbestos fiber noise reduction thermal-protective coating between outer shell wall and internal layer shell wall.
Its additional technical feature is: described housing inner-use clapboard is divided into first anechoic chamber, second anechoic chamber, the 3rd anechoic chamber, the 4th anechoic chamber; First anechoic chamber is provided with the transverse holes pipe that communicates with suction port; Second anechoic chamber is provided with the first vertical hole pipe that communicates with first anechoic chamber; The 3rd anechoic chamber is provided with second vertical hole pipe, the 3rd vertical hole pipe that communicates with second anechoic chamber, and the 4th anechoic chamber is provided with the 4th vertical hole pipe that communicates with the 3rd anechoic chamber.
The heavy goods vehicles environment protection type silencing apparatus that the utility model provided, the shell wall of housing is made up of outer shell wall and internal layer shell wall, is provided with asbestos fiber noise reduction thermal-protective coating between outer shell wall and internal layer shell wall; Compare with the silencing apparatus of single wall; The silencing apparatus good muffling effect of double-walled, environmental pollution is little, and noise is little.And the housing inner-use clapboard is divided into first anechoic chamber, second anechoic chamber, the 3rd anechoic chamber, the 4th anechoic chamber; During use, the tail gas of motor gets into first anechoic chamber by suction port through the transverse holes pipe, gets into second anechoic chamber by first anechoic chamber, first vertical hole pipe then; Get into the 3rd anechoic chamber by second anechoic chamber, second vertical hole pipe, the 3rd vertical hole pipe again; Thereafter get into the 4th anechoic chamber by the 3rd anechoic chamber the 4th vertical hole pipe, discharged by the air outlet, the housing inner structure is complicated; Tail gas is walked the circuit complications, good muffling effect.
