Description

Technical Field

[0001] This utility model relates to the technical field of noise isolation devices, specifically to an integrated noise isolation and noise reduction protection device. Background Technology

[0002] In the green manufacturing process of steel pipes, processes such as cutting, welding, and rolling generate a lot of noise, which not only affects the physical and mental health of operators, but also causes noise pollution to the surrounding environment. In order to reduce noise interference, corresponding noise reduction devices are usually installed in the steel pipe manufacturing site.

[0003] Traditional noise protection measures often use single sound insulation panels or silencers, which have limited sound insulation effects and are difficult to control noise to a minimum. Some devices, such as single sound insulation panels, are installed on both sides of the processing area, which can only achieve local noise reduction and cannot provide comprehensive noise isolation for the entire production area, resulting in prominent noise leakage problems.

[0004] On the other hand, existing devices have fixed structures, making them difficult to adjust flexibly according to different production processes and equipment layouts, resulting in poor adaptability. For example, the overall frame of most noise reduction devices has a constant size after manufacturing and cannot be adjusted, affecting the effectiveness of use. In view of this, we propose an integrated noise isolation and noise reduction protection device. Utility Model Content

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Please see Figures 1-4 This utility model provides a technical solution: an integrated noise isolation and noise reduction protection device, comprising multiple interconnected protective plates 1. Each protective plate 1 consists of an outer frame plate 10 disposed on the outside and a sound insulation layer 12 disposed at the center of the outer frame plate 10. A sound-absorbing layer 11 is disposed between the sound insulation layer 12 and the outer frame plate 10. Two adjacent protective plates 1 are detachably connected by multiple splicing fixing plates 13. One of the protective plates 1 is provided with an inlet / outlet hole 14 for equipment and workpieces to enter and exit. A movable soundproof door 15 is hinged to the wall of the inlet / outlet hole 14. An air inlet pipe 2 is fixedly installed on one of the protective plates 1, and an air outlet pipe 21 is fixedly installed on the top protective plate 1. Sound-absorbing cotton 25 is fixedly installed on the inner wall of both the air inlet pipe 2 and the air outlet pipe 21. The multi-layer structure of the protective plates 1 is combined and spliced ​​to form a closed space. The sound-absorbing cotton 25 of the air inlet pipe 2 and the air outlet pipe 21 reduces ventilation noise, achieving comprehensive noise reduction and isolation, and improving the control effect on steel pipe manufacturing noise.

[0036] In this embodiment, the splicing fixing plate 13 and the outer frame plate 10 are fixedly connected by multiple fastening bolts. A sealing strip 151 is fixedly installed on the inner side of the movable soundproof door 15, so that the protective plate 1 can be flexibly spliced. At the same time, the sealing strip 151 enhances the sealing performance of the device, reduces noise leakage, and improves the reliability of noise reduction.

[0037] like Figure 1 As shown, multiple support bases 16 are fixedly installed on the bottom surface of the protective plate 1 at the bottom. The bottom of the support base 16 is provided with a shock-absorbing pad 161. The support base 16 provides stable support for the device, and the shock-absorbing pad 161 effectively reduces the noise generated by the vibration transmission of the equipment, further reducing the overall noise level.

[0038] Specifically, sound-absorbing louvers 22 are fixedly installed on the inner walls of both the air inlet duct 2 and the air outlet duct 21. A fan 20 is fixedly installed on the inner wall of the air inlet duct 2. The fan 20 improves the ventilation efficiency inside the device, while the sound-absorbing louvers 22 reduce the noise generated by airflow, achieving a synergy between ventilation and noise reduction.

[0039] like Figure 1As shown, a dust baffle 23 is provided above the air outlet duct 21, and a bracket 24 is fixedly installed between the dust baffle 23 and the air outlet duct 21. The dust baffle 23 effectively blocks dust from entering the air outlet duct 21, ensuring smooth ventilation while reducing the entry of dust.

[0040] In addition, an observation tube 3 is fixedly installed on one of the protective plates 1 located on the side. Both ends of the observation tube 3 can be detachably installed with soundproof observation windows 31. The staff can observe the internal production situation from the outside through the soundproof observation windows 31 without affecting the noise reduction effect of the device.

[0041] It is worth noting that both ends of the observation tube 3 are fixedly installed with limit rings 30, and the soundproof observation window 31 is fixedly installed with a fixing ring 32. The fixing ring 32 and the limit ring 30 are detachably connected, making the installation and removal of the soundproof observation window 31 more convenient, and easier to clean and replace.

[0042] It is worth noting that the movable soundproof door 15 is equipped with a door lock, the distance between the two soundproof observation windows 31 is between 5cm and 8cm, the end of the air inlet pipe 2 is detachably equipped with an air filter 26, the door lock enhances the security of the device, the soundproof observation windows 31 at a specific distance improve the sound insulation effect without affecting normal viewing, and the air filter 26 achieves air filtration, thereby improving the overall performance of the device.

[0043] When in use, the noise isolation and noise reduction protection integrated device of this utility model is formed by splicing multiple protective plates 1 together with splicing fixing plates 13 and fastening bolts to form a closed space. The processing equipment is placed in this space to carry out corresponding processing operations. The support base 16 and shock-absorbing pad 161 of the bottom protective plate 1 ensure the stability of the device and reduce vibration noise. When the movable soundproof door 15 is closed, its sealing strip 151 enhances the sealing performance, and the door lock is locked to ensure safety.

[0044] Turn on the fan 20 of the air inlet duct 2. The air enters after being filtered by the air filter 26. The sound-absorbing cotton 25 and the sound-absorbing louvers 22 reduce ventilation noise. The air outlet duct 21 works with the dust baffle 23 to achieve air circulation and dust prevention. The staff can observe the interior through the soundproof observation window 31 of the observation tube 3. If the observation window needs to be replaced, the connection between the fixing ring 32 and the limiting ring 30 can be removed.
