Abstract
The utility model relates to a free-style sound-absorbing screen comprising a screen body, a support frame and small wheels. The screen body is fixed on the support frame and the wheels are fixed on the lower portion of the supporting frame. The screen body has a multilayer structure as follows: a ginning aluminum layer, an asphalt asbestos paint layer, a glass wool layer, an asphalt asbestos paint layer, an aluminum layer, an asphalt asbestos paint layer, a damping layer, a polyester sound-absorbing cotton layer, an alkali-free glass fiber cloth layer and a perforated aluminum-covered layer. The perforated aluminum-covered layer is connected with the ginning aluminum layer at edges. The free-style sound-absorbing screen has the advantages that the ratio of the sound absorbing is high, the producing art is simple, assembly and disassembly is easy, the construction time is shortened, the working efficiency is improved effectively and the engineering cost is reduced.
Description
Technical field
The utility model relates to the noise abatement apparatus field, particularly a kind of free style sound-absorbing screen of administering noise.
Background technology
At present, along with the industrial expansion noise pollution is more and more serious, particularly in the lathe processing plant, the factory building that heavy-duty motor is arranged, noise pollution are serious especially, have not only affected the workman and have lived normally, order of work, even people's hearing and health are suffered damage.So the urgency of administering by production equipment generation noise seems more and more important.
Sound arrester has played energetically effect aspect control noise, the control noise device of comparative maturity mostly is arranged on a class sound arrester of speedway, railway both sides etc. now.And indoor sound arrester mostly is at wall some damping materials to be installed, and some abatvoixs are installed on the roof, reduces room noise.But for the lathe processing plant, the motor house that produce larger noise, its role is obvious not enough.For the equipment of outdoor generation noise, do not make effective improvement yet, thereby produce larger noise, affected people's normal life, order of work.
Summary of the invention
For the defective that exists in the prior art, the purpose of this utility model is to provide a kind of free style sound-absorbing screen that can effectively intercept noise.
For reaching above purpose, the technical scheme that the utility model is taked is:
A kind of free style sound-absorbing screen comprises screen body, support and steamboat, and described screen body is fixed on the support, and described steamboat is fixed in the support bottom, and described screen body is multilayer architecture, is followed successively by:
The cotton ginning aluminum layer,
Pitch asbestos enamelled coating,
The glass wool layer,
Pitch asbestos enamelled coating,
Aluminum layer,
Pitch asbestos enamelled coating,
Damping layer,
Polyester acoustical cotton layer,
The alkali-free glass wool layer of cloth,
Perforation aluminium button layer,
Described perforation aluminium button layer is connected in edge with described cotton ginning aluminum layer.
On the basis of such scheme, the thickness of the multilayer architecture of described screen body is followed successively by:
Cotton ginning aluminum layer 1.5mm,
Pitch asbestos enamelled coating 3 mm,
Glass wool layer 30 mm,
Pitch asbestos enamelled coating 3 mm,
Aluminum layer 1 mm,
Pitch asbestos enamelled coating 3 mm,
Damping layer 1.5mm,
Polyester acoustical cotton layer 20 mm,
Alkali-free glass wool layer of cloth 0.4mm,
Perforation aluminium button layer 0.6mm.
On the basis of such scheme, be fixed with the aluminium alloys fringing around the described screen body.
The beneficial effects of the utility model:
First its adopt sound-absorbing material, pass a test, determine suitable material usage and put in order that sound-absorption coefficient is higher, can effectively reduce noise 10dB-25dB.
The second production technology is simple, can carry out large-scale industrial production according to actual conditions.
The 3rd free style sound-absorbing screen is installed pulling buckle at the screen edge and is colluded, and installing/dismounting is simple, shortens the engineering time, effectively raises operating efficiency, reduces engineering cost.
Steamboat is settled in the 4th flow-type sound-absorbing screen bottom, can move freely as required, effectively sound-absorbing and completely cut off the approach of noise transmission.
The 5th free style sound-absorbing shields outer aluminium sheet through preservative treatment, has certain rain resistance, heat resistance, uviolresistance, and the hardly impact of climate and weather is indoor all available.
The 6th free style sound-absorbing screen is mainly used in the machine tooling workshop, the air blast machine room, and air compressor house, the large power, electrically machine room, pump houses etc. produce the larger place of noise, can effectively reduce noise.
Description of drawings
The utility model has following accompanying drawing:
Fig. 1 the utility model structural representation;
Fig. 2 screen body structure described in the utility model schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Embodiment 1
As shown in Figure 1 and Figure 2, a kind of free style sound-absorbing screen comprises screen body 1, support 2 and steamboat 3, and described screen body 1 is fixed on the support 2, and described steamboat 3 is fixed in support 2 bottoms, it is characterized in that described screen body 1 is multilayer architecture, is followed successively by:
Cotton ginning aluminum layer 110,
Pitch asbestos enamelled coating 109,
Pitch asbestos enamelled coating 107,
Pitch asbestos enamelled coating 105,
Polyester acoustical cotton layer 103,
Alkali-free glass wool layer of cloth 102,
Perforation aluminium button layer 101,
Described perforation aluminium button layer 101 and described cotton ginning aluminum layer 110 are connected in edge.
Preferably, the thickness of the multilayer architecture of described screen body 1 is followed successively by:
Cotton ginning aluminum layer 110 1.5mm,
Pitch asbestos enamelled coating 109 3 mm,
Pitch asbestos enamelled coating 107 3 mm,
Pitch asbestos enamelled coating 105 3 mm,
Damping layer 104 1.5mm,
Polyester acoustical cotton layer 103 20 mm,
Alkali-free glass wool layer of cloth 102 0.4mm,
Perforation aluminium button layer 101 0.6mm.
Preferably, described screen body 1 around be fixed with aluminium alloys fringing 12.
In actual the use, install pulling buckle in the left and right sides of screen body and collude, collude the sound-absorbing of making one by one shielded by pulling buckle and couple together, so just can improve installation effectiveness, reduced engineering and expended.In addition, when the equipment that impaled when going wrong, can open button hook, the equipment that places under repair after equipment is fixed, installs the sound-absorbing screen again.By using pulling buckle to collude, the easy installation and removal of sound-absorbing screen has improved operating efficiency greatly.
Be the convenient internal unit of observing, can offer window at the screen body.
