Description
Technical field
A kind of silencing means is the utility model is related to, specifically a kind of exhaust muffling device of double thermal insulation.
Background technology
At present, existing engine exhaust muffler is mainly disappeared using the resistance exhaust of pipeline section expansion and cross-sectional constriction
Sound device structure, using sound wave at the abrupt change of cross-section because the change of acoustic reactance, some sound wave reflect back to sound source, it is and obstructed
The outlet of silencer is crossed, so as to reach the purpose of noise elimination.Silencing noise of this resistance exhaust silencer to high, medium and low frequency
There is certain effect.And for skin temperature, because interior room noise with outer casing inner wall percussion raises skin temperature, and it is interior
Heat-barrier material of the portion without arrangement to noise advantages of good adsorption effect, causes skin temperature too high.
Utility model content
The purpose of this utility model is to provide a kind of tail gas exhaust muffling device for possessing double thermal insulation.
To achieve the above object, the technical solution of the utility model is：A kind of double thermal insulation air exhaust muffler device, including shell
Body, the case inside are provided with thermal insulation layer, are provided with net circle on the inside of the thermal insulation layer, the housing both ends are provided with cover plate, the lid
Port thermal insulation board is equipped with the inside of plate, web plate is equipped with the inside of the port thermal insulation board, right side is expanded provided with air inlet in the housing
Separate tube, the air inlet anemostat left side are provided with preceding thermal insulation board, outlet anemostat are provided with the left of the preceding thermal insulation board, and the outlet expands
Rear thermal insulation board is provided with the left of separate tube, running through among the preceding thermal insulation board and rear thermal insulation board has intervalve, and tube top is spread in the air inlet
Portion is provided with air inlet, and gas outlet is provided with the top of the outlet anemostat, and air inlet anemostat and outlet the diffusion pipe end is provided with
Plug, the housing downside are provided with outlet pipe, and the outlet pipe implements thermal insulation layer and net circle connects with enclosure interior, the air inlet
Anemostat is staggered with outlet anemostat, and the rear thermal insulation board is provided with ventilation mouth.
Due to using above-mentioned technical proposal, the beneficial effects of the utility model：Maintain resistance exhaust silencer to it is high,
In, the advantages of low frequency silencing noise effect is good, and by absorption of the heat-barrier material to noise, reduce noise and shell rushed
Hit, reduce the temperature of shell during use, while noise elimination of the heat-barrier material to high frequency, obtain engine supercharger whistle
Eliminate well, in actual entrucking in use, having obtained good effect.

Embodiment
As Figure 1-3, the utility model includes housing 1, and the inner side of housing 1 is provided with thermal insulation layer 2, the thermal insulation layer 2
Inner side is provided with net circle 3, and the both ends of housing 1 are provided with cover plate 4, and the inner side of cover plate 4 is equipped with port thermal insulation board 5, the port
The inner side of thermal insulation board 5 is equipped with web plate 6, and right side is provided with air inlet anemostat 7 in the housing 1, and the left side of charging period anemostat 7 is set
There is preceding thermal insulation board 8, the preceding left side of thermal insulation board 8 is provided with outlet anemostat 9, and the left side of outlet anemostat 9 is provided with rear thermal insulation board
10, through there is intervalve 11, the top of air inlet anemostat 7 is provided with air inlet for the preceding thermal insulation board 8 and the centre of rear thermal insulation board 10
12, the top of outlet anemostat 9 is provided with gas outlet 13, and air inlet anemostat 7 and outlet anemostat 9 end is provided with plug
14, the downside of housing 1 is provided with outlet pipe 15, and the outlet pipe 15 is implemented thermal insulation layer 2 and net circle 3 and connected with the inside of housing 1, institute
