Abstract
The utility model relates to a silencer with an anti-scalding device. The silencer with the anti-scalding device comprises a silencer outer shell, an air inlet pipe and an air discharge hole. The periphery of the silencer outer shell is fixed with an anti-scalding mesh enclosure, and clapboards with cavities are arranged in the silencer inner cavity and divide the silencer inner cavity into a cavity I, a cavity II and a cavity III. Openings are formed in the clapboards and communicate the cavity I, the cavity II and the cavity III. An opening is formed in the air inlet pipe and communicates the air discharge pipe and the cavity I. The cavity III is provided with an air discharge pipe to be connected with the air discharge hole. The high temperature waste gas which is discharged from a gasoline engine flows from the silencer air inlet pipe into the cavity I, enters the cavity II through a honeycomb hole I which is formed in the clapboard and enters the cavity III through a honeycomb hole II and is discharged from the air discharge hole. The honeycomb holes reduce noise of the passed airflow. Meanwhile, the anti-scalding mesh enclosure which is fixed on the periphery of the silencer can avoid scalding accidents which are caused by staff touching.
Description
Technical field
The utility model relates to a kind of exhaust silencer, is specifically related to a kind of silencing apparatus with burn-proof device.
Background technique
On the petrol engine silencing apparatus is installed all at present, its housing is provided with suction tude and outlet pipe, and the waste gas that petrol engine is discharged enters in the silencing apparatus cavity by suction tude, discharges finally by outlet pipe.The housing of general silencing apparatus all is to adopt metal to be made, and the exhaust gas temperature of discharging from petrol engine is up to more than 200 ℃, and as because of carelessness, silencing apparatus causes personnel's scald accident easily, the wound that is burned is often than the more difficult recovery of common wound, and easy scar.
Summary of the invention
In view of this, the purpose of this utility model provides a kind of silencing apparatus with burn-proof device, can prevent effectively that operator from being scalded by silencing apparatus.
The utility model discloses a kind of silencing apparatus with burn-proof device, it is characterized in that: comprise muffler shell, suction tude and exhaust port, be fixed with anti-scald guard around the described muffler shell, described silencing apparatus inner chamber is provided with the dividing plate of belt chamber and the silencing apparatus inner chamber is divided into chamber I, chamber II and chamber III, described dividing plate is provided with the perforate that chamber I, chamber II and chamber III are communicated with, described suction tude is provided with the perforate that outlet pipe is communicated with the chamber I, and described chamber III is provided with outlet pipe and is connected with exhaust port.
Further, described dividing plate is provided with the through hole that suction tude is passed, and described suction tude is fixedly connected with ground with the muffler shell end face.
Further, described dividing plate comprises upper clapboard and lower clapboard, and described upper clapboard and lower clapboard are provided with the honeycomb hole I that chamber I and chamber II are communicated with, and described upper clapboard is provided with the honeycomb hole II that chamber II and chamber III are communicated with.
Further, described exhaust port is provided with filter screen.
The beneficial effects of the utility model are: the silencing apparatus of the utility model band burn-proof device, the high-temp waste gas of discharging from petrol engine enters into the chamber I from silencer air inlet pipe, enter into the chamber II by the honeycomb hole I on the dividing plate again, enter into the chamber III by the honeycomb hole II at last, discharge through exhaust port, petrol engine waste gas is when the inner continuously process of silencing apparatus honeycomb hole, the frequency spectrum of noise will be shifted to high frequency or ultra-high frequency, audible sound composition in the frequency spectrum is obviously reduced, thereby reduce interference and injury to the people; Be fixed with anti-scald guard around the muffler shell simultaneously, adopt the anti-scald guard of thermal-protective material can not heat up because of the thermal radiation of silencing apparatus, avoided personnel that the scald accident occurs.

Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
A kind of silencing apparatus with burn-proof device of the utility model, comprise muffler shell 2, suction tude 3 and exhaust port 4, be fixed with anti-scald guard 1 around the described muffler shell 2, anti-scald guard 1 adopts thermal-protective material to make, and avoids that the personnel that cause touch scald because the thermal radiation of silencing apparatus heats up.Described silencing apparatus inner chamber is provided with the dividing plate of belt chamber and the silencing apparatus inner chamber is divided into chamber I 5, chamber II 6 and chamber III 7, described dividing plate is provided with the perforate that chamber I 5, chamber II 6 and chamber III 7 are communicated with, described suction tude 3 is provided with the perforate 8 that suction tude 3 is communicated with chamber I 5, and described chamber III 7 is provided with outlet pipe 9 and is connected with exhaust port 4.
In the present embodiment, described dividing plate is provided with the through hole 10 that suction tude is passed, and described suction tude 3 is fixedly connected with ground with muffler shell 2 end faces, because muffler shell 2 adopts thin-walled material to make, in order to prevent distortion, adopts suction tude 3 to be supported.
Dividing plate described in the present embodiment comprises upper clapboard 11 and lower clapboard 12, described upper clapboard 11 and lower clapboard 12 are provided with the honeycomb hole I 13 that chamber I 5 and chamber II 6 are communicated with, described upper clapboard 12 is provided with the honeycomb hole II 14 that chamber II 6 and chamber III 7 are communicated with, and adopts the principle of aperture noise reduction to abate the noise.
In the present embodiment, described exhaust port 4 is provided with filter screen 15, prevents that foreign matter from entering to stop up pore in silencing apparatus.
Using originally is the silencing apparatus with burn-proof device of model utility, the high-temp waste gas that petrol engine is discharged enters into chamber I 5 from silencer air inlet pipe 3, enter into chamber II 6 by the honeycomb hole I 13 on the dividing plate again, enter into chamber III 7 by honeycomb hole II 14 at last, discharge through exhaust port 4, honeycomb hole can make through pneumatic noise reduce, fixing anti-scald guard 1 can also be avoided personnel to touch the scald accident occurs around the silencing apparatus simultaneously.
