Abstract
The utility model discloses an inhale sound and fall centrifugal separator casing of making an uproar, include the casing and fall the device of making an uproar, fall the device of making an uproar and hug closely the inner wall of casing, it comprises the wear -resisting punched steel plate of high strength, rubber perforated plate, arc perforated plate, air chamber, puigging to fall the device of making an uproar, the both sides of air chamber are connected with the cavity that the rubber perforated plate formed, the arc perforated plate is the slope and connects the inside at the cavity, the wear -resisting punched steel plate of high strength is connected with the right side of cavity, the left side at the cavity is connected to the puigging. The inhale sound and fall centrifugal separator casing of making an uproar has been owing to set up the cavity that is formed by the rubber perforated plate, and at the inside arc perforated plate that is inclination and sets up that sets up of cavity, and through this kind of structure, the noise that the centrifugal separator produced can be at the continuous circulation flow in the inside of cavity under of the blockking of arc perforated plate when enterring the cavity, can let glass cotton furthest's absorption noise.
Description
Technical field
The utility model belongs to casing technical field, is specifically related to a kind of absorbing sound and lowering noise centrifuge casing.
Background technology
Centrifuge is a kind of equipment of important separation of material, has a wide range of applications in many fields.Large-scale centrifuge can produce larger noise in operation process, makes the producers be correlated be in a comparatively noisy environment, affects the hearing of people, is also unfavorable for healthy simultaneously.The noise reduction means of current centrifuge is exactly arrange a cavity in the inside of centrifuge casing, and then fills some sound-absorbing materials in cavity, although there is certain noise reduction, does not reach desirable noise abatement.A kind of absorbing sound and lowering noise centrifuge casing is proposed for this reason.
Utility model content
The purpose of this utility model is to provide a kind of absorbing sound and lowering noise centrifuge casing, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of absorbing sound and lowering noise centrifuge casing, comprise casing and denoising device, described denoising device is close to the inwall of casing, described denoising device is by high-strength abrasion-proof punched steel plate, rubber perforated plate, arc perforated plate, air chamber, puigging forms, the inside of described air chamber is filled with mineral wool, the both sides of described air chamber are connected with the cavity of rubber perforated plate formation, described arc perforated plate is in the inside tilting to be connected to cavity, the inside of described cavity is filled with mineral wool, described high-strength abrasion-proof punched steel plate is connected with the right side of cavity, described puigging is connected to the left side of cavity.
Preferably, described puigging is made up of sound-proof damping felt, porous fibre plate and concrete layer, and described concrete layer is close to the inwall of casing, and described porous fibre plate is connected with concrete layer, and described sound-proof damping felt is connected with porous fibre plate.
Preferably, the surface of described high-strength abrasion-proof punched steel plate and the inner surface of casing all scribble sound-absorbing coating.
Technique effect of the present utility model and advantage: this absorbing sound and lowering noise centrifuge casing is owing to being provided with the cavity formed by rubber perforated plate, and the arc perforated plate arranged in angle of inclination is set in the inside of cavity, by this structure, the noise that centrifuge produces is when entering cavity, constantly can circulate in the inside of cavity under the stop of arc perforated plate, mineral wool can be allowed to absorb noise to greatest extent; The air chamber arranged, can effectively completely cut off noise transmission to external environment; The puigging arranged is made up of sound-proof damping felt, porous fibre plate and concrete layer, at noise after absorption process above, further intercepts remaining faint noise transmission to extraneous, avoids the healthy of noise effect workman.
