Description
Technical field
The present invention relates to cold cut cutting mill equipment manufacturing technology field, be especially a kind of ultralight small-sized cold cut cutting mill Special-purpose silencer.
Background technology
Acoustic filter is to utilize sound-absorbing material to stop or reduce a kind of device of sound transmission, is the important measures eliminating air power noise.Acoustic filter can stop the propagation of sound wave, it is allowed to air-flow passes through, and is the effective tool controlling noise.Sound-absorbing material is to have stronger absorption acoustic energy, the material of reducing noise performance, by means of self porous, membrane action or resonant interaction, incident acoustic energy is had the material of Absorption, one of element of ultrasonography equipment, sound-absorbing material to mate with the acoustic characteristic impedance of the sound bearing medium of surrounding, enter sound-absorbing material with making acoustic energy areflexia, and make the incident acoustic energy overwhelming majority be absorbed.
In order to meet through engineering approaches and the practicality requirement of cutting operation system, solving the practical challenges that ultralight small-sized cold cut cuts operating system noise big becomes key.The noise that operating system is cut in ultralight small-sized cold cut is mainly derived from two aspects: one is prime mover and mechanical noise that high-pressure pump produces in operation process；Two is the injection noise produced with air or periphery medium interaction due to high-speed water jet.Noise control conventional method has: absorbs sound, insulate against sound and acoustic filter.Sound absorption is exactly the material and structure utilizing and absorbing acoustic energy, reduces the acoustic energy being broadcast to receiver, reduces noise.Sound insulation is to utilize partiting sound member that noise source is separated with receiver, makes noise be obstructed and can not pass through, and controls noise.Acoustic filter is to utilize one to have sound absorption liner or special structure form, effectively suppresses sound transmission while allowing air-flow to pass through.Cutting in ultralight small-sized cold cut uses the acoustic filter equipped with sound-absorbing material to absorb sound in operating system noise reduction.
But the existing design being applied to the acoustic filter that operating system is cut in ultralight small-sized cold cut there is also following deficiency: structure complexity, high-temperature oxydation sound absorption filler, maintenance frequently height, soundproof effect are poor, the situations such as the use cycle is short.
How to design simple in construction, soundproof effect good and avoid high-temperature oxydation sound absorption filler acoustic filter be the problem needing solution badly.
Summary of the invention
Be directed to above-mentioned deficiency, it is an object of the invention to provide a kind of ultralight small-sized cold cut cutting mill Special-purpose silencer, complicated to solve structure in prior art, high-temperature oxydation sound absorption filler, maintenance frequently, soundproof effect poor, problem that the use cycle is short.
For reaching above-mentioned purpose, the present invention provides a kind of ultralight small-sized cold cut cutting mill Special-purpose silencer, including housing, is provided with inlet chamber and outlet chamber, the housing of described inlet chamber and outlet chamber relevant position is respectively equipped with air inlet and gas outlet in described housing；
Being provided with dividing plate between described inlet chamber and outlet chamber, dividing plate is fixedly connected on inner walls, and dividing plate offers connected entrance, and connected entrance is fitted with movable blocking；
Described movable blocking connects elastic component one end below, and the elastic component other end connects float；
Being provided with pond in described outlet chamber, be contained with liquid in pond, described buoys float is placed on the liquid level in pond.
Sound-absorbing material in housing absorbs noise, and by activity blocking, float vibration loss noise energy, the fluctuation of liquid level also can be lost noise energy；High temperature noise gas is under the effect of liquid simultaneously, cools rapidly, it is to avoid oxidation sound absorption filler；Activity is blocked under elastic component elastic force and float buoyancy, under the effect not having noise gas, can block the most rapidly connected entrance, structure highly sensitive, prevents noise gas backstreaming.
It is preferred that described housing is composited by the metal-rubber bonding aluminum fiberboard of plate outer surface, the most bonding cystosepiment of the bonding aluminum fiberboard of inner surface；
Metal-rubber plate, aluminum fiberboard and the cystosepiment of described enclosure interior are equipped with perforation.
Using the many cavity structures of micro-pinking, noise air-flow through repeatedly flowing in cavity, reduces the audio frequency of Primordial Qi stream in acoustic filter step by step.
It is preferred that be equipped with wide-mouth on connected entrance in described inlet chamber and outlet chamber；
Described wide-mouth is circular platform type, and its opening is more than connected entrance.
It is easy to noise gas quickly through connected entrance, raising noise elimination speed.
It is preferred that described movable blocking is also in circular platform type, and can adaptive connector in wide-mouth.
Good sealing effect, it is to avoid noise gas backstreaming.
It is preferred that described float is much larger than activity blocking, and cover the liquid level in pond.
Avoiding float activity space in pond big, elastic component is crooked, and movable blocking comes off from connected entrance.
It is preferred that described elastic component is flexure spring.
Improve the sensitivity of movable blocking, even if by the noise gas pressure of very small volume, also can open connected entrance.
The beneficial effect of the invention:
The present invention absorbs noise by the sound-absorbing material in housing, and movable blocking, float vibration loss noise energy, the fluctuation of liquid level also can be lost noise energy；High temperature noise gas is under the effect of liquid simultaneously, cools rapidly, it is to avoid oxidation sound absorption filler；Activity is blocked under elastic component elastic force and float buoyancy, under the effect not having noise gas, can block the most rapidly connected entrance, structure highly sensitive, prevents noise gas backstreaming.Simple in construction, soundproof effect is good and avoids high-temperature oxydation sound absorption filler, keeps in repair the lowest, uses the cycle long.
