[0030] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0031] Example

[0032] As mentioned in the background technology, there are some problems in the current noise reduction scheme for reactor oil tanks. For example, it is not easy to find oil leakage defects in double-layer oil tanks, and it is inconvenient to carry out oil tank vibration measurement and internal ultrasonic and partial discharge signal monitoring on the equipment; the installation of soundproof rooms has high manufacturing costs and long construction periods, which in turn causes great difficulties for the operation and maintenance of the equipment. Therefore, it is necessary to find new soundproof devices to solve this problem.

[0033] In order to solve the above technical problems, an embodiment of the utility model provides a reactor sound insulation and noise reduction device that is easy to disassemble and assemble.

[0034] like Figure 1 As shown, this embodiment provides a reactor sound insulation and noise reduction device that is easy to disassemble and assemble, including an oil tank wall 1, a sound insulation board 2, a vibration damping pad 5 and a groove-shaped reinforcing iron 8, wherein the sound insulation board 2 is arranged between the outer side of the oil tank wall 1 and the groove-shaped reinforcing iron 8, and the vibration damping pad 5 is arranged at the contact portion between the sound insulation board 2 and the groove-shaped reinforcing iron 8, which can change the rigid contact into elastic contact, and effectively reduce the degree of vibration transmitted from the oil tank wall to the sound insulation board 2.

[0035] In this embodiment, the grooved reinforcing iron 8 is arranged at intervals on the outside of the oil tank wall 1. The grooved reinforcing iron 8 can effectively enhance the mechanical strength of the oil tank wall 1. Through the combination of the grooved reinforcing iron 8 and the oil tank wall 1, the oil tank can withstand greater external pressure and internal stress, thereby ensuring the stability and safety of the reactor during operation. The layout of the grooved reinforcing iron 8 in the oil tank is based on the central symmetry of the device body. This symmetrical arrangement balances the transmission of vibration and noise.

[0036] In this embodiment, Figure 2 As shown, a first oil tank mounting plate 4-1 is arranged at the upper end of the outer side of the oil tank wall 1, a second oil tank mounting plate 4-2 is arranged at the lower end of the outer side of the oil tank wall 1, and the sound insulation plate 2 is located between the first oil tank mounting plate 4-1 and the second oil tank mounting plate 4-2.

[0037] In this embodiment, a first mounting plate 3-1 is arranged above the sound insulation plate 2, and a second mounting plate 3-2 is arranged below the sound insulation plate 2. The first mounting plate 3-1 and the second mounting plate 3-2 are respectively fixed to the first oil tank mounting plate 4-1 and the second oil tank mounting plate 4-2 by prying with bolts, which has the effects of stability, reliability, strong bearing capacity and easy installation.

[0038] In this embodiment, a vibration-damping pad 5 is arranged between the first mounting plate 3-1 and the first oil tank mounting plate 4-1. The vibration-damping pad 5 absorbs and disperses vibration energy through internal damping materials, thereby reducing the transmission of vibration and the generation of noise.

[0039] In this embodiment, a second mounting hole is provided on both the first oil tank mounting plate 4-1 and the second oil tank mounting plate 4-2. The second mounting hole is a blind hole. The blind hole is located on the bottom layer of the first oil tank mounting plate 4-1 and the top layer of the second oil tank mounting plate 4-2, which can improve the stability and reliability of the mounting plates and reduce production costs.

[0040] In this embodiment, Figure 3 As shown, the sound insulation board 2 includes an outer shell 6 and sound insulation cotton 7. The sound insulation cotton 7 is close to the inner wall of the outer shell 6, which can reduce the gap for sound transmission through the air, thereby improving the sound insulation effect. At the same time, the sound insulation cotton 7 is close to the outer shell 6 to increase the stability of the overall structure.

[0041] In this embodiment, the shell 6 is a metal shell. The metal material has high corrosion resistance and pressure resistance, and can maintain a stable sound insulation effect in various harsh environments.

[0042] In this embodiment, the housing 6 is connected to the first mounting plate 3 - 1 and the second mounting plate 3 - 2 by welding, which can enhance the stability and reliability of the connection.

[0043] In this embodiment, Figure 4As shown, the first mounting hole is set on the first mounting plate 3-1 and the second mounting plate 3-2, and the first mounting hole and the second mounting hole are symmetrically arranged. The first mounting plate 3-1 and the first oil tank mounting plate 4-1 and the second mounting plate 3-2 and the second oil tank mounting plate 4-2 are fixed by prying the first mounting hole and the second mounting hole with bolts.

[0044] In summary, this embodiment provides a reactor sound insulation and noise reduction device that is easy to disassemble and assemble, which not only can achieve good sound insulation and noise reduction effects on the reactor, but also has low manufacturing costs, does not increase the equipment's footprint and construction period, and is easy to disassemble and maintain on site.

[0045] In summary, the utility model provides a reactor sound insulation and noise reduction device that is easy to disassemble and assemble. Compared with the existing reactor sound insulation and noise reduction device, it has the following advantages:

[0046] The reactor sound insulation and noise reduction device of the utility model arranges a sound insulation board 2 between the outer side of the oil tank wall 1 and the groove-shaped reinforcing iron. Since the sound insulation board 2 is directly arranged on the outer side of the oil tank wall 1, no additional space is required to install a double-layer oil tank or a soundproof room, thereby saving installation space, making the entire device structure more compact, and at the same time performing noise reduction processing on the noise source of the reactor, so it has higher noise reduction efficiency and pertinence.

[0047] In addition, the sound insulation board 2 is arranged on the outside of the oil tank wall 1, which will not block the heat dissipation channel of the reactor, and thus will not affect the heat dissipation performance of the reactor. Moreover, as a separate component, the sound insulation board 2 can be removed and installed separately if it needs to be replaced or repaired, without disassembling the entire device, which greatly simplifies the maintenance process and reduces maintenance costs.

[0048] In summary, the reactor sound insulation and noise reduction device of the utility model directly reduces the noise source by setting the sound insulation board 2 between the outer side of the oil tank wall 1 and the groove-shaped reinforcing iron 8, thereby reducing the impact of noise on the surrounding environment. At the same time, the production cost is low and it is convenient for on-site disassembly and maintenance.
