Description

Technical Field

[0001] The utility model relates to the technical field of pollution prevention and control, in particular to a high-strength sound-absorbing and sound-insulating board. Background Art

[0002] In pollution prevention systems, a large number of water pumps and motors are needed to power sewage treatment equipment. These equipment generate considerable operating noise, which in turn increases noise pollution at the worksite. For this reason, some pollution prevention sites have gradually constructed soundproof enclosures or rooms around noisy equipment using sound-absorbing and sound-isolating panels.

[0003] However, in order to achieve good sound absorption and sound insulation effects, sound-absorbing and sound-insulating panels are usually made of lightweight, porous materials. The strength of these materials themselves is relatively low, resulting in low strength of the overall sound insulation structure.

[0004] In order to ensure the sound absorption effect, the existing sound-absorbing panels have a high internal pore density, resulting in low overall supporting strength and difficulty in withstanding external collisions and strong winds. Therefore, a high-strength sound-absorbing and sound-insulating panel is proposed to provide a set of sound-absorbing and sound-insulating panels with good use strength for outdoor sewage treatment equipment. Utility Model Content

[0005] In view of the problems in the prior art, the utility model provides a high-strength sound-absorbing and sound-insulating board to provide a set of sound-absorbing and sound-insulating boards with good use strength for outdoor sewage treatment equipment.

[0006] The technical solution adopted by the utility model to solve the technical problem is a high-strength sound-absorbing and sound-insulating board, comprising:

[0007] Sound absorption part;

[0008] The back panel portion is connected to the sound absorbing portion.

[0009] By adopting the above technical solution, a set of sound-absorbing and sound-insulating panels with good use strength is provided for outdoor sewage treatment equipment through the assembly consisting of the sound-absorbing part and the back panel part.

[0010] Specifically, the sound absorbing part includes:

[0011] First glass magnesium board;

[0012] The grid plate slot is set on the back of the first glass magnesium plate;

[0013] A felt pad is connected to the first glass magnesium plate on a side away from the grid plate slot;

[0014] The second glass magnesium plate is connected with the felt pad.

[0015] By adopting the above technical solution, the sound generated by the sewage treatment equipment is absorbed and blocked by the sound absorbing part.

[0016] Specifically, a plurality of groups of honeycomb holes are formed on the surface of the second glass magnesium plate away from the felt pad.

[0017] Specifically, the back plate portion includes:

[0018] Stainless steel plate;

[0019] Stainless steel grating plate, connected with stainless steel plate.

[0020] By adopting the above technical solution, the supporting strength of the sound absorbing part is increased through the back plate part, and the external protection performance of the back of the sound absorbing part is improved.

[0021] Specifically, the stainless steel grid plate is inserted into the grid plate slot, and the grid plate slot and the stainless steel plate are glued and fixed to the first glass magnesium plate.

[0022] Specifically, a side of the stainless steel plate away from the stainless steel grid plate is sprayed with an anti-rust paint layer.

[0023] By adopting the above technical solution, the anti-rust performance of the outer surface of the stainless steel plate is improved by the anti-rust paint layer.

[0024] The beneficial effects of the utility model are as follows: through the assembly consisting of the sound-absorbing part and the back plate part, a set of sound-absorbing and sound-insulating panels with good use strength is provided for outdoor sewage treatment equipment. The sound-absorbing part absorbs and blocks the sound generated by the sewage treatment equipment, and the back plate part increases the supporting strength of the sound-absorbing part, while improving the external protection performance of the back of the sound-absorbing part. This solves the problem of existing sound-absorbing panels that, in order to ensure the sound absorption effect, the internal pore density is high, resulting in low overall supporting strength and difficulty in withstanding external collisions and strong winds.

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0032] In order to increase the intensity of use, such as Figure 1-4 As shown, the high-strength sound-absorbing and sound-insulating board described in the utility model includes:

[0033] Sound absorption part 1;

[0034] The back plate portion 2 is connected to the sound absorbing portion 1 .

[0035] When in use, the sound absorbing part 1 and the back panel part 2 provide a set of high-strength sound-absorbing and sound-insulating panels for outdoor sewage treatment equipment, so that the pollution control equipment can work in an environment where high-strength sound-absorbing and sound-insulating panels are built.

[0036] For multi-layer sound insulation, for example, Figure 3 As shown, the present invention further includes that the sound absorbing part 1 includes:

[0037] First glass magnesium plate 101;

[0038] The grid plate slot 102 is provided on the back of the first glass magnesium plate 101;

[0039] The felt pad 104 is connected to the first glass magnesium plate 101 on a side away from the grid plate slot 102;

[0040] The second glass magnesium plate 103 is connected to the felt pad 104 .

[0041] A plurality of honeycomb holes 105 are formed on a surface of the second glass magnesium plate 103 away from the felt pad 104 .

[0042] When in use, the second glass magnesium board 103 having a plurality of honeycomb holes 105 performs preliminary absorption of noise, and the felt pad 104 forms a sound insulation layer between the second glass magnesium board 103 and the first glass magnesium board 101 to further insulate the noise. The first glass magnesium board 101 insulates the noise after the felt pad 104 is treated, so that the noise is treated with three layers of sound absorption and sound insulation.

[0043] In order to improve the use strength of the entire sound insulation board, for example, Figure 1 、 4 As shown, the present invention further includes that the back plate portion 2 includes:

[0044] Stainless steel plate 201;

[0045] The stainless steel grating plate 202 is connected to the stainless steel plate 201 .

[0046] The stainless steel grid plate 202 is inserted into the grid plate slot 102 , and the grid plate slot 102 and the stainless steel plate 201 are glued and fixed to the first glass magnesium plate 101 .

[0047] During use, the stainless steel grille plate 202 on the stainless steel plate 201 is inserted into the grille plate slot 102, so that the back panel 2 and the sound absorbing part 1 are plug-connected. The partitions formed by the staggered grille plate slots 102 provide strong support for the back of the sound absorbing part 1, which can effectively cope with external bumps and strong winds outdoors.

[0048] For example, Figure 4 As shown, the present invention further includes that the side of the stainless steel plate 201 away from the stainless steel grid plate 202 is sprayed with an anti-rust paint layer 203; the anti-rust paint layer 203 can improve the anti-rust performance between the back of the stainless steel plate 201 and the external environment.

[0049] When the present invention is in use, the stainless steel grille plate 202 on the stainless steel plate 201 is inserted into the grille plate slot 102, so that the back panel 2 and the sound absorbing part 1 are plug-connected. The partitions formed by the staggered grille plate slots 102 provide strong support for the back of the sound absorbing part 1. Therefore, the sound insulation structure constructed by the sound insulation board of the present application can effectively cope with external collisions and outdoor strong winds. When in use, the second glass magnesium board 103 with a plurality of groups of honeycomb holes 105 is used to initially absorb noise. The felt pad 104 forms a sound insulation layer between the second glass magnesium board 103 and the first glass magnesium board 101 to further soundproof the noise. The noise treated by the first glass magnesium board 101 with the felt pad 104 is soundproofed, so that the noise is subjected to three-layer sound absorption and sound insulation treatment, thereby providing a set of high-intensity sound-absorbing and sound-insulating board structures for pollution control equipment.
