Description

Technical Field

[0001] The utility model relates to the technical field of noise reduction, in particular to a sound insulation device for a fluid pressurizing device. Background Art

[0002] Blowers are rotating machines that generate a lot of noise during operation. In terms of the noise source generation mechanism, it mainly includes two parts: aerodynamic noise and mechanical noise. Although the mechanical design of the blower takes certain noise reduction measures into consideration, for large blowers arranged indoors, the noise they generate still exceeds the specified noise limit of 85dB(A) for industrial production workshops. The huge noise will cause noise pollution, and in the long run, it will cause noise-induced deafness of operators and cause a series of labor health diseases.

[0003] Therefore, it is particularly important to control the noise generated by the blower body. Blower noise control mainly starts from controlling the transmission path. The existing sound insulation cover technology only sets up a sound insulation cover for the blower body, and does not consider the noise control of the lower space of the blower. The noise of the blower body spreads to the production workshop through the lower space, which still causes greater noise pollution. Utility Model Content

[0004] The existing blower soundproof cover is covered on the outside of the equipment, with sound insulation panels on the four sides and a metal screen sound-absorbing panel on the top surface combined with the four sides to form a closed noise reduction structural unit. The entire structure is combined in a way that is easy to install and disassemble. This type of soundproof cover only reduces the noise of the upper part of the blower, while the blower used in the blast furnace is usually arranged on a higher island platform, with the blower inlet and outlet at the bottom of the island, connected to the inlet and outlet pipes through the openings on the island. If the noise reduction treatment is not performed on the space below the blower, the huge noise generated by the blower body will still spread to the workshop building, causing serious noise pollution.

[0005] In order to overcome the above-mentioned defects of the prior art, the technical problem to be solved by the embodiments of the utility model is to provide a sound insulation device for a fluid pressurizing device, which can solve the problem of excessive noise transmitted by the fluid pressurizing device through the lower space.

[0031] In order to solve the problem of excessive noise transmitted by the fluid booster through the lower space, a sound insulation device for the fluid booster is proposed in the present application. Figure 1 This is a front view of the sound insulation device of the fluid pressurizing device in the embodiment of the utility model. Figure 2 : is a side view of the sound insulation device of the fluid pressurizing device in the embodiment of the utility model, as shown in Figure 1 and Figure 2As shown, the sound insulation device of the fluid pressurizing device may include: a support mechanism 1, a fluid pressurizing device 2, an upper sound insulation cover 3 and a lower sound insulation mechanism 4. The support mechanism 1 is used to support the fluid pressurizing device 2 so that the setting position of the fluid pressurizing device 2 has a certain height, so that there is space below the fluid pressurizing device 2 to set the relevant components connected to the fluid pressurizing device 2. The fluid pressurizing device 2 can be any device that pressurizes the fluid, such as a blower, a compressor and the like, and there is no limitation on it in this application. When the fluid pressurizing device 2 is a blower, the relevant components connected to the fluid pressurizing device 2 may include, for example, an air inlet pipe, an air outlet pipe, etc. The support mechanism 1 may have a support platform 11 and a support column 12 connected to the lower end of the support platform 11. The support column 12 is used to support the support platform 11 so that the support platform 11 has a certain height. There may be multiple support columns 12, and the multiple support columns 12 are connected to the edge of the support platform 11 along the circumferential direction, for example, the edge of the lower end surface of the support platform 11. A space is formed between the plurality of support columns 12 to arrange the related components connected to the fluid pressurizing device 2. The support platform 11 is used to install the fluid pressurizing device 2. At least part of the fluid pressurizing device 2 is higher than the support platform 11. The support platform 11 has a hollow structure, so that the related components connected to the fluid pressurizing device 2 can pass through the support platform 11, and the related components connected to the fluid pressurizing device 2 can be located below the support platform 11.

[0032] like Figure 1 and Figure 2 As shown, the upper soundproof cover 3 is arranged on the supporting platform 11 and covers the fluid boosting device 2 therein. Here, the lower end surface of the upper soundproof cover 3 is connected to the supporting platform 11, and the upper soundproof cover 3 covers the part of the fluid boosting device 2 that is higher than the supporting platform 11 therein. The above method can effectively reduce the decibel number of the noise emitted by the fluid boosting device 2 transmitted from above the supporting platform 11.

[0033] like Figure 1 and Figure 2 As shown, the upper soundproof cover 3 may include an annular upper soundproof side wall 31 and an upper soundproof top wall 32. The upper soundproof side wall 31 surrounds the fluid pressurizing device 2 above the support platform 11, and completely seals the fluid pressurizing device 2. The upper soundproof top wall 32 is connected to the upper edge of the upper soundproof side wall 31, thereby sealing the top of the fluid pressurizing device 2.

[0034] The upper soundproof top wall 32 and the upper soundproof side wall 31 can be spliced ​​to form the upper soundproof cover 3, which can facilitate the disassembly and assembly of the upper soundproof cover 3. The upper soundproof side wall 31 can be formed by splicing multiple upper soundproof side walls 31, which can facilitate the disassembly and assembly of the entire upper soundproof side wall 31. All splicing connections can be bolted, which facilitates the disassembly and assembly of the upper soundproof cover 3 when the fluid booster device 2 is repaired.

[0035] In order to improve the sound insulation performance of the upper sound insulation cover 3 and make the upper sound insulation cover 3 have sufficient strength and durability, the upper sound insulation cover 3 can be made of a sound insulation board, and the sound insulation board includes from the inside to the outside: a first galvanized plate, a glass fiber sound absorbing cloth layer, a sound insulation rock wool layer, a frame, a damping sound insulation layer, and a second galvanized plate. The glass fiber sound absorbing cloth layer, the sound insulation rock wool layer and the damping sound insulation layer mainly play the role of enhancing the sound insulation performance. The frame is mainly used to improve the overall strength and firmness of the sound insulation board. The first galvanized plate and the second galvanized plate mainly play a role in protecting the surface, thereby improving the service life of the sound insulation board. The galvanized plate can be sprayed with plastic to improve the corrosion resistance and wear resistance. In addition, the galvanized plate can be made of galvanized steel plate to improve the strength. The frame can be a steel plate cold-bent frame, thereby further improving the overall strength and firmness of the sound insulation board.

The first air inlet 33 may be one or more.

[0037] As feasible, Figure 1 and Figure 2 As shown, the upper soundproof cover 3 may have a first exhaust port 35. In order to facilitate efficient exhaust of the gas in the upper soundproof cover 3, a first exhaust fan 36 is provided at the first exhaust port 35 to exhaust the gas in the upper soundproof cover 3 to the outside of the upper soundproof cover 3 through the first exhaust port 35. In order to reduce the decibel number of the noise emitted by the fluid boosting device 2 transmitted from the first exhaust port 35, a first exhaust muffler 37 is provided at the outlet of the first exhaust fan 36 or downstream of the outlet. The first exhaust port 35, the first exhaust fan 36 and the first exhaust muffler 37 may be one group or multiple groups.

[0038] like Figure 1 and Figure 2As shown, the lower sound insulation mechanism 4 extends from the ground 5 to the bottom surface of the support platform 11 and is in a ring shape to encircle the support column 12. In other words, the lower sound insulation mechanism 4 can encircle the support column 12, the fluid boosting device 2 and related components connected to the fluid boosting device 2 below the support platform 11. In this way, the decibel number of the noise emitted by the fluid boosting device 2 transmitted from below the support platform 11 can be effectively reduced.

[0039] In order to improve the sound insulation performance of the lower sound insulation mechanism 4 and make the lower sound insulation mechanism 4 have sufficient strength and durability, the lower sound insulation mechanism 4 can also be made of a sound insulation board, which can include, from the inside to the outside, a first galvanized plate, a glass fiber sound-absorbing cloth layer, a sound insulation rock wool layer, a frame, a damping sound insulation layer, and a second galvanized plate.

[0040] The lower sound insulation mechanism 4 may include a plurality of lower sound insulation side walls 41, and the plurality of lower sound insulation side walls 41 are spliced ​​to form the lower sound insulation mechanism 4. This method can facilitate the disassembly and assembly of the lower sound insulation mechanism 4. All splicing connections can be bolted, which facilitates the disassembly and assembly of the lower sound insulation mechanism 4 when the fluid booster device 2 is repaired.

[0041] In other feasible embodiments, the lower sound insulation mechanism 4 may include a solid wall, which is extended from the ground 5 to the bottom surface of the support platform 11 and is annular to encircle the support column 12. The solid wall may be made of reinforced concrete or brick-concrete structure, and the solid wall can also play a good role in sound insulation.

[0042] As feasible, Figure 1 and Figure 2 As shown, the lower sound insulation mechanism 4 has a second air inlet 42. In order to reduce the decibel level of the noise emitted by the fluid boosting device 2 transmitted from the second air inlet 42, a second air inlet muffler 43 is provided at the second air inlet 42. The second air inlet 42 can be one or more.

[0043] As feasible, Figure 1 and Figure 2 As shown, the lower sound insulation mechanism 4 may have a second exhaust port 44. In order to facilitate the efficient discharge of the gas in the lower sound insulation mechanism 4, a second exhaust fan 45 is provided at the second exhaust port 44 to discharge the gas in the lower sound insulation mechanism 4 to the outside of the lower sound insulation mechanism 4 through the second exhaust port 44. In order to reduce the decibel number of the noise emitted by the fluid boosting device 2 transmitted from the second exhaust port 44, a second exhaust muffler 46 is provided at the outlet of the second exhaust fan 45 or downstream of the outlet. The second exhaust port 44, the second exhaust fan 45 and the second exhaust muffler 46 may be one group or multiple groups. Through the cooperation of the first exhaust fan 36 and the second exhaust fan 45, it can be effectively ensured that the ventilation times of the gas in the upper sound insulation cover 3 and the lower sound insulation mechanism 4 meet the requirements.

[0044] As feasible, an inspection door may be provided on the lower sound insulation mechanism 4. In addition, in order to facilitate people to enter the upper sound insulation cover 3 and the lower sound insulation mechanism 4 for inspection, lighting facilities may be installed in the upper sound insulation cover 3 and / or the lower sound insulation mechanism 4.

[0045] The fluid boosting device 2 proposed in the embodiment of the present application is provided with a soundproof cover on the upper part of the support platform 11 and a lower soundproof mechanism 4 is provided under the support platform 11, so that the fluid boosting device 2 and the related components connected to the fluid boosting device 2 can be soundproofed in a closed manner, so as to isolate the fluid boosting device 2 from the main plant space, and the noise generated by the fluid boosting device 2 in the plant can be reduced to below 85dB (A), thereby improving the operating conditions in the production workshop and meeting the industrial hygiene standards. Especially in the metallurgical industry, the blast furnace fluid boosting device 2 is one of the indispensable equipment in the blast furnace production smelting process. It is accompanied by the continuous operation of the blast furnace production all year round, and the noise reduction of the fluid boosting device 2 is particularly important.
