Technical Problem

[0003]现有的增氧机在运行时,高速真空泵的高速运转会产生较大噪音,为缓解这一问题,通常会在增氧机的箱体内部设置降噪结构,目前常见的做法是将单一的隔音棉结构固定安装在机箱的侧壁上,利用隔音棉的纤维结构吸收和阻隔噪音,然而,在增氧机长期使用过程中,养殖环境中的灰尘会不断积聚在隔音棉表面,并逐渐渗入其内部,随着时间的推移,灰尘会堵塞隔音棉的孔隙,破坏其原本疏松的纤维结构,导致隔音棉的吸音能力大幅减弱,原本能有效吸收的中高频噪音无法被充分阻隔,使得增氧机的整体降噪效果明显降低,不仅影响养殖人员的工作环境,还可能因噪音持续扩散对周边生态造成干扰,且由于隔音棉是固定安装的,清理或更换时需拆卸箱体部件,操作繁琐,既增加了维护成本,又可能因频繁拆卸影响机箱的密封性,进一步加剧噪音外泄的问题,无法满足现在的需求

Description

Technical Field

[0001] This utility model relates to the field of aerator technology, specifically a high-speed aerator chassis with noise reduction function. Background Technology

[0002] Aerators are commonly used machines in aquaculture. Their core function is to increase the oxygen content in the water, ensuring that fish do not lack oxygen. At the same time, they can inhibit the growth of anaerobic bacteria in the water, prevent the pond water from deteriorating and damaging the fish's living environment, and ensure the safety and stability of aquaculture.

[0003] Existing aerators generate significant noise during operation due to the high-speed operation of their vacuum pumps. To mitigate this issue, noise reduction structures are typically installed inside the aerator housing. Currently, a common practice is to fix a single sound-insulating cotton structure to the side wall of the housing, utilizing the cotton's fiber structure to absorb and block noise. However, over long-term use, dust from the aerator environment accumulates on the surface of the sound-insulating cotton and gradually seeps into its interior. Over time, the dust clogs the pores of the cotton, damaging its originally loose fiber structure and significantly reducing its sound absorption capacity. The previously effective absorption of mid-to-high frequency noise is no longer adequately blocked, resulting in a marked decrease in the overall noise reduction effect of the aerator. This not only affects the working environment of aquaculture workers but may also cause disturbance to the surrounding ecosystem due to continuous noise diffusion. Furthermore, since the sound-insulating cotton is fixedly installed, cleaning or replacing it requires disassembling housing components, which is cumbersome and increases maintenance costs. Frequent disassembly may also affect the housing's sealing, further exacerbating noise leakage and failing to meet current needs. Utility Model Content

[0004] The purpose of this invention is to provide a high-speed aerator chassis with noise reduction function to solve the problems mentioned in the background art.
