水电、矿山、冶金、建材,化工等工业部门广泛使用的破碎机,噪声级高,严重损害职工身体健康,必须把噪声降到国家允许标准。在目前还无法从破碎机本身控制声源噪声的情况下,采用隔声技术可以获得比较好的效果。然而,常规轻质隔声罩和砖石隔声结构,因装拆困难、不便于操作和维护,未能推广使用。基于上述考虑,我们设计了一种新型的隔声结构——软质多层隔声罩,以改善破碎机(破碎机按结构和破碎方式分为颚式、锥式、辊式、锤式、冲击式、液压式等)的降噪情况。
The crusher widely used in the hydropower, mining, metallurgy, building materials, chemical industry and other industrial sectors has high noise level and seriously harms the health of the staff and workers. The noise must be reduced to the national allowable standard. At present there is no way to control the sound source noise from the crusher itself, the use of sound insulation technology can get better results. However, conventional lightweight soundproof masonry and masonry sound insulation structures are not widely used due to the difficulty of assembly and disassembly, inconvenient operation and maintenance. Based on the above considerations, we designed a new type of sound insulation structure - soft multilayer sound insulation cover to improve the crusher (crusher according to the structure and broken into jaw, cone, roll, hammer, Impact, hydraulic, etc.) of the noise reduction.
