[0002] In industrial production environments, pumps and motors are widely used as key power equipment. However, the noise they generate during operation has always been a major problem plaguing industrial environments. Traditional noise reduction methods have many limitations, mainly including the following aspects:

For example, metal soundproof enclosures have some reflective effect on high-frequency noise, but perform poorly in absorbing and blocking low-frequency noise. Therefore, we have made improvements and proposed an industrial vacuum soundproof enclosure. Utility Model Content

[0032] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0033] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0034] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0035] For an example, please refer to... Figures 1-9 An industrial vacuum soundproof cover includes a bottom pad module 100 and a double-layer vacuum soundproof cover module 200 detachably mounted on the bottom pad module 100. The double-layer vacuum soundproof cover module 200 includes inner and outer connecting base plates 230 detachably mounted on the bottom pad module 100. A transparent outer cover 210 and a transparent inner cover 220 located inside the transparent outer cover 210 are connected to the side of the inner and outer connecting base plates 230 away from the bottom pad module 100. A vacuum layer is formed between the transparent inner cover 220 and the transparent outer cover 210. The outer surface of the inner cover 220 is provided with several transparent support blocks 240, and a silicone gasket 250 is provided between the transparent support blocks 240 and the inner wall of the transparent outer cover 210; the double-layer vacuum soundproof cover module 200 absorbs noise from the top and all sides; the transparent support blocks 240 can support the transparent inner cover 220 and the transparent outer cover 210, reducing the possibility of deformation and damage to the transparent inner cover 220 and the transparent outer cover 210 after vacuuming, while the silicone gasket 250 can weaken the noise transmitted through the transparent support blocks 240;

[0036] The bottom pad module 100 includes a silicone sound-absorbing plate 120 that contacts the inner and outer connecting base plate 230. A soft PP support plate 110 is provided on the side of the silicone sound-absorbing plate 120 away from the inner and outer connecting base plate 230. The soft PP support plate 110 and the silicone sound-absorbing plate 120 are used to support pumps, motors and other equipment that need noise reduction and absorb vibration and noise at the bottom.

[0037] The soft PP support plate 110 is made of polypropylene (PP) material, which has good flexibility and impact resistance; the silicone sound-absorbing plate 120 is made of high-density silicone material.

[0038] The transparent outer cover 210, transparent inner cover 220, transparent support block 240, and inner and outer connecting base plate 230 are all made of transparent UPVC and are bonded or welded together using special UPVC glue. The silicone gasket 250 is made of silicone material. With the help of the transparent design, the operator can observe the inside of the double-layer vacuum soundproof cover module 200 in real time, detect abnormalities in time, and enhance the convenience of monitoring and the safety of the equipment.

[0039] This innovative vacuum soundproof enclosure effectively buffers low-frequency noise by utilizing the soft PP support plate 110 at the bottom, which, thanks to its excellent flexibility and elastic deformation capability, can effectively cushion low-frequency vibrations generated during equipment operation, thus reducing the source of low-frequency noise. The silicone sound-absorbing plate 120 has high damping characteristics in the low-frequency range. Its porous structure and special elastic modulus allow low-frequency sound waves to continuously rub against the silicone material and convert energy during propagation, transforming low-frequency sound energy into heat energy and other forms of energy for consumption, thereby achieving effective absorption of low-frequency noise.

[0040] In terms of mid-frequency noise reduction, the double-layer structure composed of the transparent outer cover 210 and the transparent inner cover 220, along with the vacuum layer in between, changes the medium and path of sound propagation. This causes the mid-frequency sound waves to undergo multiple reflections and refractions at the vacuum layer and the transparent outer cover 210 and the transparent inner cover 220, thus attenuating the energy of the mid-frequency noise. At the same time, the combination structure of the transparent support block 240 and the silicone gasket 250 bonded between the transparent outer cover 210 and the transparent inner cover 220 forms a similar damping and vibration isolation system. This system has a good blocking effect on the transmission of mid-frequency vibrations, reducing the transmission of mid-frequency vibrations generated by the equipment to the transparent outer cover 210 and causing noise radiation. Furthermore, the silicone gasket 250 can further absorb the mid-frequency sound waves that pass through the support block, further reducing the propagation of mid-frequency noise.

[0041] To address high-frequency noise, the double-layer vacuum soundproof enclosure module 200's double-layer structure and relatively thin wall design make it easier for high-frequency sound waves to scatter and interfere within the material and at the interface during propagation, effectively hindering the propagation of high-frequency noise. In addition, the micro-texture and molecular structure of the silicone sound-absorbing panel 120 can strongly interact with sound waves in the high-frequency band, increasing sound wave scattering and energy loss, and improving the blocking and absorption effect on high-frequency noise.

[0042] Furthermore, both the inner and outer corners of the transparent inner cover 220 and the transparent outer cover 210 are rounded. The rounded corners allow sound to transition and disperse more smoothly when it reaches the corners, reducing sound reflection and concentration. This reduces the noise enhancement effect caused by corner reflection, which helps to improve the sound insulation performance of the entire soundproof cover and makes the sound insulation effect more uniform and stable.

[0043] Furthermore, a threaded hole 212 is provided on the side of the transparent outer cover 210 away from the inner and outer connecting base plate 230. A vacuum pressure gauge 400 is connected to the threaded hole 212, and a pressure gauge sealing gasket 500 is also provided at the connection between the vacuum pressure gauge 400 and the threaded hole 212. The vacuum pressure gauge 400 can monitor the vacuum status at the vacuum layer.

[0044] Furthermore, a third through hole 211 is provided on the side of the transparent outer cover 210 away from the inner and outer connecting base plate 230. The third through hole 211 is connected to a vacuum pipe module 300. The vacuum pipe module 300 includes an air pipe 310 communicating with the third through hole 211. A KF chuck interface is provided at the end of the air pipe 310 away from the third through hole 211, and a KF vacuum ball valve 320 is provided on one side of the KF chuck interface. The KF vacuum ball valve 320 is used to connect to an existing vacuuming device. A KF quick-release clamp 340 is connected between the KF vacuum ball valve 320 and the KF chuck interface. By cooperating with the vacuum pressure gauge 400 and the vacuum pipe module 300, the vacuum layer pressure can be observed and the appropriate vacuum degree can be adjusted to meet the industrial noise reduction environment requirements of different needs.

[0045] Furthermore, a sealing ring 330 is provided between the KF vacuum ball valve 320 and the KF chuck interface. The sealing ring 330 is used to seal the connection between the KF vacuum ball valve 320 and the KF chuck interface.

[0046] Furthermore, a fastener is provided between the soft PP support plate 110 and the silicone sound-absorbing plate 120; the fastener includes several first grooves 112 provided on the outer periphery of the soft PP support plate 110, and several second grooves 122 provided on the outer periphery of the silicone sound-absorbing plate 120. A fixing plate 130 is connected between the second grooves 122 and the first grooves 112. The soft PP support plate 110, the silicone sound-absorbing plate 120 and the fixing plate 130 are connected by bolts. The fixing plate 130 is C-shaped and is made of stainless steel.

[0047] Furthermore, a latch wrench element 140 is installed on the fixing plate 130, and a latch hook element 260 that engages with the latch wrench element 140 is installed on the inner and outer connecting base plates 230. The connection between the bottom pad module 100 and the double-layer vacuum sound insulation cover module 200 is achieved through the engagement of the latch wrench element 140 and the latch hook element 260. This connection method makes the installation and disassembly process extremely simple. In actual use scenarios, no complicated tools or professional skills are required, and operators can quickly complete the operation, greatly shortening equipment downtime, improving production efficiency, and effectively reducing production interruptions caused by equipment maintenance. It has obvious advantages over the traditional cumbersome installation and disassembly methods. Because traditional installation and disassembly methods often use multiple bolts, the installation and disassembly process is cumbersome and complicated, requiring a lot of time and manpower. For industrial scenarios that require regular maintenance or equipment replacement, this greatly reduces production efficiency.

[0048] Furthermore, a second through hole 121 is provided through the middle of the silicone sound-absorbing panel 120. A wiring groove 123 communicating with the second through hole 121 is provided on the side of the silicone sound-absorbing panel 120 away from the soft PP support plate 110. The wiring groove 123 is used for wiring, and its size can be determined according to actual needs. After wiring, the wiring groove 123 is filled with sealant. A first through hole 111 communicating with the second through hole 121 is provided on the soft PP support plate 110. The second through hole 121 and the first through hole 111 are used to place components that need to be connected to the outside, such as water pipes. Hole 121 and the first through hole 111 can be set according to actual needs. After the external components are placed, the second through hole 121 and the first through hole 111 are sealed with sealing material to perform noise reduction. The sealing material can be sealant, and silicone sealant can be used. Alternatively, a splicable silicone plate can be used. The splicable silicone plate is designed according to the size and shape of the second through hole 121, the first through hole 111 and the external components, and can seal the gaps between the second through hole 121, the first through hole 111 and the external components.

[0049] In terms of material selection, this application uses materials with certain corrosion resistance and stability, such as soft PP, silicone, stainless steel, and UPVC. Furthermore, the overall structural design is compact and reasonable, enabling this application to adapt to harsh conditions in industrial environments such as high temperature, high humidity, corrosive gases, and dust. This ensures long-term stable operation in complex industrial production environments, reduces equipment damage and performance degradation caused by environmental factors, extends equipment service life, and reduces enterprise operating costs.
