Abstract
The invention relates to a novel square bending-flow type muffle. The muffle comprises a hollow muffle body; a partition plate is arranged in the inner width direction of the hollow muffle body; a clearance is formed between the partition plate and the top wall of the hollow muffle body; the hollow muffle body consists of a punched plate inner layer, a sound absorbing middle layer and a steel plate outer layer. The novel square bending-flow type muffle disclosed by the invention is arranged in the width direction of main body equipment, takes up a small space at an air outlet in the length direction and can play a muffling effect, and the overall set of equipment is reasonable in 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 Novel square deflector type silencing apparatus of complete equipment reasonable structural arrangement.
Technological scheme: in order to solve the problems of the technologies described above, a kind of Novel square deflector type silencing apparatus of the present invention, it comprises hollow silencing body, dividing plate is provided with in described hollow silencing body inner width direction, have interval between described dividing plate and hollow silencing body inner roof wall, described hollow silencing body is made up of punched-plate internal layer, sound-absorbing middle level and steel plate skin.
Described hollow silencing body is cuboid hollow silencing body.
Described dividing plate is located at the neutral position of described hollow silencing body.
The outer field thickness of described steel plate is 2.5mm.
Be provided with air intake pipe in side, described hollow silencing body length direction, opposite side is provided with wind pipe.
Described air intake pipe and wind pipe divide the both sides being located at described dividing plate.
Described air intake pipe is provided with intake grill.
Described wind pipe is provided with exhaust outlet.
Described air intake pipe and wind pipe are all steel pipelines.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is: reasonable structural arrangement of the present invention, vertical hollow silencing body 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 by punched-plate internal layer, sound-absorbing middle level and steel plate skin composition, soundproof effect can be ensured, adopt dividing plate, play baffling noise elimination effect, described hollow silencing body is cuboid hollow silencing body, intake grill and exhaust outlet can be made to be arranged on both sides, not on same center line, this device using effect is good, long service life, realistic usage requirement.
