Abstract
The utility model relates to a novel sleeve type sound eliminator. The novel sleeve type sound eliminator comprises a hollow sound eliminating body, a steel pipe is arranged inside the hollow sound eliminating body, gaps are formed between the steel pipe and the inner side wall of the hollow sound eliminating body and between the steel pipe and the inner top of the hollow sound eliminating body, and the hollow sound eliminating body is composed of a punched board inner layer, a sound absorbing cotton middle layer and a steel board outer layer. The novel sleeve type sound eliminator is arranged in the width direction of main equipment, the air outlet occupies small land in the length direction and can achieve the sound eliminating effect, and the whole equipment is reasonable in structural layout.
Description
Technical field
The utility model relates to a kind of silencer, is specifically related to a kind of silencing apparatus.
Background technique
When human body is during in noise circumstance, not only affect working efficiency, also harmful healthy, particularly when near blower equipment.Silencing apparatus is that a kind of air-flow that allows passes 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 blower, the silencing apparatus of a general configuration has two: one is 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 simple in structure, air-flow is straight-through, drag losses is little, longer its soundproof effect of length is better, general length is between 1 meter to 2 meters, but the occasion of having living space and limiting 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 purpose of this utility model is in order to overcome deficiency of the prior art, a kind of width direction that is 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 described in the utility model, it comprises hollow silencing body, in described hollow silencing body inside, be provided with steel pipe, madial wall and the inner top of described steel pipe and hollow silencing body have gap, and described hollow silencing body is comprised 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.
On the sidewall of described hollow silencing body, be provided with air intake pipe, on the hollow silencing body sidewall on described air intake pipe opposite, be provided with air outlet tube.
Described air intake pipe connects described steel pipe and hollow silencing body.
On described air intake pipe, be provided with intake grill.
On described air outlet tube, be provided with exhaust outlet.
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: the utility model reasonable structural arrangement, adopt cylindrical hollow sound-absorptive object to be arranged on the width direction of equipment, thereby length direction floor space is reduced, solved the problem that former equipment outlet length direction has living space and limits, described hollow silencing body is comprised of punched-plate internal layer, sound-absorbing middle level and steel plate skin, can guarantee soundproof effect, this device using effect is good, long service life, realistic usage requirement.
