Description
Technical Field
The invention relates to the technical field of noise treatment, in particular to an environment-friendly sound-absorbing board.
Background
In industrial production and daily life, the sources of noise are wide, and for example, aerodynamic noise (a fan, an air compressor, a jet engine, a steam turbine, etc.), mechanical noise (a lathe, an electric saw, an electric planer, a ball mill, a grinder, a loom, etc.), electromagnetic noise (a large motor, a generator), and the like.
Noise is a malignant irritant and can cause the following hazards to the human body: 1) people feel distracted and can not do the work with great concentration, and the working efficiency is reduced; 2) acting on human central nervous system for a long time, can make excitation and inhibition of cerebral cortex disordered, and conditioned reflex abnormal, thereby causing accident rate to rise; 3) prolonged exposure to noise can increase adrenal secretion, increase blood pressure, and impair cardiovascular health.
With the continuous progress of science and technology and society, people pay more and more attention to the influence of noise on work and life, and more complete noise reduction modes and products are expected to be put into use so as to greatly reduce noise pollution, so that a sound-absorbing plate is needed to be designed, noise is eliminated in an absorption mode, and a quiet and comfortable work and living environment is created.
Disclosure of Invention
The invention aims to solve the technical problem of making up the defects of the prior art and provide an environment-friendly sound-absorbing board.
To solve the technical problems, the technical scheme of the invention is as follows: the utility model provides an environmental protection abatvoix which characterized by: including plate body part and outer frame, the plate body part includes the equal first layer galvanized porous plate of area from outside to inside in proper order, first layer glass silk cloth, glass silk floss, second floor glass silk cloth and second floor galvanized porous plate, outer frame includes the top mounting, the bottom mounting, left side mounting and right side mounting, the top mounting, the bottom mounting, the cross section of left side mounting and right side mounting is "[" shape, the joint is around the plate body part respectively, and through a plurality of fix with rivets, make outer frame and plate body part be connected as a whole.
Furthermore, the thickness of the first layer of galvanized porous plate and the thickness of the second layer of galvanized porous plate are both 0.7mm, the aperture of each micropore on the galvanized porous plate is 3mm, the hole pitch is 3mm, and the micropores are uniformly and densely distributed.
Further, the thickness of each of the first layer of glass fiber cloth and the second layer of glass fiber cloth is 0.2mm, and the density of each of the first layer of glass fiber cloth and the second layer of glass fiber cloth is 6mmX6 mm.
Further, the thickness of the glass floss silk is 150 mm.
Furthermore, the outer frame is formed by bending a galvanized plate through shearing and folding equipment.
Further, the rivet is a blind rivet.
The invention can achieve the following beneficial effects:
1) the double-sided sound absorption design is adopted, so that the noise of the unit can be effectively absorbed and reduced, and the emission of external noise is reduced;
2) when the glass wool is used outdoors, the first layer of glass wool cloth and the second layer of glass wool cloth can effectively prevent water and other liquid from entering, and can protect the integrity of the glass wool cotton;
3) the block-shaped combined structure is adopted, so that factory prefabrication and field installation can be realized, and the construction is convenient;
4) compact structure, firm and reliable fixation, safe use and suitable popularization and application.
