Description
Technical field
The present invention relates to a kind of air compressor machine accessory technical field, more specifically, it relates to a kind of muffler and its noise reduction
Method.
Background technology
Muffler is mounted in the device of the reduction noise in the inlet and exhaust system of the air powered equipments such as air compressor machine.
In the application for a patent for invention of Application No. 201210245981.7, a kind of silencer of air compressor machine is disclosed, it is logical
Cross the setting of rotatable dividing plate and the airflow hole being placed on dividing plate is realized and eliminated the noise；And by setting air-flow convolution groove, realize into one
Step is eliminated the noise；Finally by cylinder sponge, realize and further eliminate the noise；And its solve be that conventional muffler is complicated, be not easy
Cleaning, the problem of quality is big, but this air compressor silencer there is problems：Dividing plate needs rotatably, to revolve
The mode turned needs applied external force to drive its rotation, and in order to increase its rotational stabilization, it is necessary to opened up on case hole and
Rotary shaft is set, it is complicated；Need to set convolution groove, ensure that the air-flow into after case inner chamber can be transported repeatedly in interior intracavitary
It is dynamic；Its soundproof effect is also required to improve.
The content of the invention
In view of the deficienciess of the prior art, it is an object of the invention to provide a kind of simple in construction and good muffling effect
Muffler and its noise reduction method.
To achieve the above object, the invention provides following technical scheme：A kind of muffler, including outer cover and it is placed in outer cover
Fixed seat on one end, outer cover are provided with air inlet pipe, and fixed seat is provided with escape pipe, it is characterized in that：It is provided with and disappears in the outer cover
Mixer, silencing means include outer cover being separated into the dividing plate of first chamber and second chamber, are placed in point of escape pipe inlet end
Stream cover, first chamber connects with air inlet pipe and the airintake direction of air inlet pipe and the internal perisporium of first chamber are tangentially-arranged, the second chamber
Room is connected with escape pipe, and the airflow hole of first chamber and second chamber is communicated with dividing plate, if the side wall of fluid dividing cover is provided with
Dry tap hole.
The present invention is further arranged to：The airflow hole is two and with dividing plate center symmetric setting.
The present invention is further arranged to：The escape pipe is placed in the connection end at the center of fixed seat, fixed seat and escape pipe
The guiding gutter being placed on the inside of fixed seat is provided with, the openend of fluid dividing cover is placed in guiding gutter.
The present invention is further arranged to：Filter cotton is provided with the first chamber.
The first chamber and second chamber are also rounded in cylinder, dividing plate in cylinder, filter cotton.
The present invention is further arranged to：The fluid dividing cover and baffle plate integrally connected.
A kind of noise reduction method for being applicable above-mentioned muffler, it is characterized in that：Comprise the following steps：
First, air tangentially enters first chamber by air inlet pipe, and circulation repeatedly is produced in first chamber, plays first time noise reduction
Effect, and secondary noise reduction is played a part of by the barrier of filter cotton；
2nd, when air runs into dividing plate in first chamber, which part air by along airflow hole axially even into second chamber,
Produce and turn back when air is touched on the inside of fixed seat, then air produces in second chamber turns back and circulation rises repeatedly, to the
Sound deadening three times, another part air produce to turn back and stay in first chamber circulation again and consumed by filter cotton, play
The effect of 4th noise reduction；
3rd, the air in second chamber enters escape pipe by the tap hole on fluid dividing cover, plays the sound deadening of the 5th time.
By using above-mentioned technical proposal, have the advantages that：The airintake direction of air inlet pipe and first inner chamber inner circumferential
Wall is tangentially-arranged, then nature can produce circulation repeatedly after air enters first chamber, and caused circulation effect is good, is not required to additional
Structure, with regard to noise elimination can be played a part of；Dividing plate is static setting, and the air-flow of first chamber itself can produce circulation, air-flow
Noise elimination effect can be played when flowing through the airflow hole of dividing plate；Realized by fluid dividing cover and carry out further sound deadening, same to time-division
Stream cover makes air also effectively hinder the strike note of cylinder interior gas valve plate even into cylinder；Using said structure
Muffler, its structure is simpler, and structural strength is reliable, and quality can be lighter, and pass through multiple sound deadening, it disappears
Audio fruit improves 50% than the silencer in existing design.
