Abstract
The invention relates to a novel sleeve type sound eliminator. The novel sleeve type sound eliminator comprises a hollow sound elimination body, wherein a steel pipe is arranged in the hollow sound elimination body, intervals are formed among the steel pipe, and the inner side wall and the inner top of the hollow sound elimination body, and the hollow sound elimination body is composed of a punching plate inner layer, a sound absorption cotton middle layer and a steel plate outer layer. The novel sleeve type sound eliminator is arranged in the width direction of a main device, occupies a small space in the length direction of an air outlet, can meet sound elimination effects, and is reasonable in overall structural arrangement.
Description
Technical field
The present invention relates to a kind of silencer, be specifically related to a kind of silencing apparatus.
Background technique
When human body is in noise circumstance, not only affect working efficiency, go back negative unhealthy, particularly when near blower equipment.Silencing apparatus a kind ofly allows air-flow to pass through and the device of attenuate acoustic noise.The quality of Muffler Performance directly affects the size of the noise of blower.
In the configuration of conventional air blast machine, the silencing apparatus of a general configuration has two: one to be intake grill silencing apparatus, and one is silencer for air outlet.Silencer for air outlet generally all adopts single channel straighttube-type acoustic wave filter structure, feature is that structure is simple, air-flow straight-through, drag losses is little, length its soundproof effect longer is better, general length is between 1 meter to 2 meters, but the occasion of restriction of having living space for equipment outlet length direction, the silencer for air outlet of this form just cannot be installed because length is long.
Summary of the invention
Goal of the invention: the object of the invention is to overcome deficiency of the prior art, a kind of width direction being arranged on main equipment is provided, exhaust outlet length direction takes up an area little and can meet soundproof effect, the New Sleeve silencing apparatus of complete equipment reasonable structural arrangement.
Technological scheme: in order to solve the problems of the technologies described above, a kind of New Sleeve silencing apparatus of the present invention, it comprises hollow silencing body, steel pipe is provided with in described hollow silencing body inside, madial wall and the inner top of described steel pipe and hollow silencing body have gap, and described hollow silencing body is made up of punched-plate internal layer, acoustical cotton middle level and steel plate skin.
Described hollow silencing body is cylindrical, hollow sound-absorptive object.
Described steel pipe is circular open steel pipe.
The sidewall of described hollow silencing body is provided with air intake pipe, the hollow silencing body sidewall on described air intake pipe opposite is provided with air outlet tube.
The through described steel pipe of described air intake pipe and hollow silencing body.
Described air intake pipe is provided with intake grill.
Described air outlet tube is provided with exhaust outlet.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is: reasonable structural arrangement of the present invention, cylindrical, hollow sound-absorptive object is adopted to be arranged on the width direction of equipment, thus length direction floor space is reduced, solve before equipment outlet length direction have living space restriction problem, described hollow silencing body is made up of punched-plate internal layer, sound-absorbing middle level and steel plate skin, soundproof effect can be ensured, this device using effect is good, long service life, realistic usage requirement.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present invention;
Fig. 2 is plan structure schematic diagram of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further illustrated.
As depicted in figs. 1 and 2, a kind of New Sleeve silencing apparatus of the present invention, it comprises hollow silencing body 1, steel pipe 2 is provided with in described hollow silencing body 1 inside, madial wall and the inner top of described steel pipe 2 and hollow silencing body 1 have gap 3, and described hollow silencing body 1 is made up of punched-plate internal layer 4, acoustical cotton middle level 5 and steel plate skin 6; Described hollow silencing body 1 is cylindrical, hollow sound-absorptive object; Described steel pipe 2 is circular open steel pipe; The sidewall of described hollow silencing body 1 is provided with air intake pipe 7, hollow silencing body 1 sidewall on described air intake pipe 7 opposite is provided with air outlet tube 8; The through described steel pipe 2 of described air intake pipe 7 and hollow silencing body 1; Described air intake pipe 7 is provided with intake grill 9; Described air outlet tube 8 is provided with exhaust outlet 10.Reasonable structural arrangement of the present invention, cylindrical, hollow sound-absorptive object is adopted to be arranged on the width direction of equipment, thus length direction floor space is reduced, equipment outlet length direction has living space the problem of restriction before solving, described hollow silencing body is made up of punched-plate internal layer, sound-absorbing middle level and steel plate skin, can ensure soundproof effect, and this device using effect is good, long service life, realistic usage requirement.
The invention provides a kind of thinking and method; the method and access of this technological scheme of specific implementation is a lot; the above is only the preferred embodiment of the present invention; should be understood that; for those skilled in the art, under the premise without departing from the principles of the invention, some improvements and modifications can also be made; these improvements and modifications also should be considered as protection scope of the present invention, and all available prior art of each constituent element not clear and definite in the present embodiment is realized.
