Description

Technical Field

[0001] The utility model relates to the technical field of sound insulation boards, in particular to a wind-shielding and flow-guiding sound insulation board. Background Art

[0002] With the further development of the petroleum and petrochemical industry, the use of air cooler equipment has become more and more frequent, and the noise problem has become increasingly serious.

[0003] In order to reduce the impact of noise, lower the noise level at the factory boundary, and protect the working environment within the factory, it is necessary to carry out noise treatment on the air cooler; and after the noise reduction of the air cooler equipment, due to the characteristics of the air cooler equipment, the air inlet and outlet are close to each other. As the exhaust wind resistance increases, the air inlet and exhaust efficiency of the air cooler decreases, and the equipment may have the risk of hot air backflow; at the same time, the use of traditional noise reduction materials (such as rock wool, glass wool, etc.), that is, fiber noise reduction materials, may have the possibility of fiber pollution as the use time increases, and secondary pollution may be generated during the manufacturing and processing process, which may be detrimental to environmental protection.

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Embodiment 1:

[0027] Reference Figure 1-Figure 3 , a windshield deflection sound insulation board, comprising a windshield component 1, the windshield component 1 comprises:

[0028] A first air guide plate 102 and a second air guide plate 105;

[0029] The first air guide plate 102 and the second air guide plate 105 are fixedly connected;

[0030] The first air guide plate 102 and the second air guide plate 105 are both fixedly connected with a sound absorbing component 101;

[0031] The sound absorbing plate 104 is connected to the second air guide plate 105;

[0032] The cavity 103 is provided between the first air guide plate 102 and the sound absorbing plate 104 .

[0033] The first air guide plate 102 is fixedly connected with a connection card 3 , and the connection card 3 is fixedly connected to the second air guide plate 105 .

[0034] The second air guide plate 105 is fixedly connected with a square tube 2 , and the square tube 2 is threadedly connected with a bolt 201 .

[0035] The cavity 103 is a vacuum cavity.

[0036] By setting the cavity 103 as a vacuum cavity, the overall noise reduction effect of the device can be improved.

[0037] The sound absorbing plate 104 is a microporous plate.

[0038] The sound absorbing component 101 is commercially available silicone-modified melamine sound absorbing cotton.

[0039] Reference Figure 3 There is an angle between the first air guide plate 102 and the second air guide plate 105, and the inner angle between the first air guide plate 102 and the second air guide plate 105 is an obtuse angle.

[0040] The wind shield assembly 1 is arranged on the upper side of the air inlet of the air cooler, and is connected to the air cooler bracket through the square tube 2 and the bolts 201.

[0041] Reference Figure 1 , Figure 3 When the air cooler is entering, the wind flows through the second air guide plate 105, and part of the wind is guided into the first air guide plate 102, where the noise generated by the wind flow can be effectively absorbed by the sound absorbing component 101;

[0042] Another part of the wind flows through the other side. When the wind flows through the sound absorbing plate 104, it will flow through the micropores of the sound absorbing plate 104. According to the micropore sound absorption principle, the noise when the wind flows through can be effectively reduced.

[0043] The first air guide plate 102, the second air guide plate 105, the sound absorbing assembly 101 and the sound absorbing plate 104 can effectively absorb the noise generated when the wind enters, reduce the noise value at the factory boundary, and ensure the working environment of the factory area.

[0044] Reference Figure 3By setting the first air guide plate 102 and the second air guide plate 105 to be V-shaped, the wind shielding assembly 1 can improve the air inlet direction of the air cooler, and at the same time, the first air guide plate 102 and the second air guide plate 105 are connected to prevent the air discharged from the air cooler from being drawn back.

[0045] The device can effectively absorb the noise generated when the air cooler is taking in air, reduce the noise value at the factory boundary, and protect the working environment of the factory. When taking noise reduction measures, the device can effectively prevent hot air backflow from occurring in the air cooler, thereby ensuring the remixing rate of the air cooler. By arranging the first air guide plate 102 and the second air guide plate 105 above the air inlet of the air cooler, the air intake conditions can be improved and the air intake wind resistance can be reduced.

[0046] The sound-absorbing component in the device adopts silicon-based modified melamine sound-absorbing cotton, which is a non-fibrous porous sound-absorbing material. The material is corrosion-resistant, clean, and not easy to generate secondary pollution during the manufacturing and processing process.
