Noise reduction structure for centrifugal machine and construction method of noise reduction structure
The invention provides a noise reduction structure for a centrifugal machine. The noise reduction structure comprises a sound insulation wall body and a hinged door driving mechanism used for entering and exiting of a pipe pile mold. A hinged door is arranged at the top of the sound insulation wall body, a plurality of retaining walls are arranged in the sound insulation wall body, and the hinged door driving mechanism is arranged at the tops of the adjacent retaining walls. A closed space is jointly formed by the sound insulation wall body and the hinged door driving mechanism, and the problems that an existing centrifugal machine is poor in noise reduction effect and cannot effectively isolate medium-frequency noise and low-medium-frequency noise are solved. The noise reduction structure for the centrifugal machine is reasonable in structure and good in noise reduction effect and particularly has the absorption and isolation effect on the medium-frequency noise and the low-medium-frequency noise.
本发明提供一种用于离心机的降噪结构，包括隔音墙体、用于管桩模具进出的对开门驱动机构，隔音墙体的顶部设置有对开门，隔音墙体内部设置有多个挡墙，对开门驱动机构设置在相邻挡墙的顶部，隔音墙体、对开门驱动机构共同构成一个封闭空间，解决了以往的离心机降噪效果不佳，不能够对中频和中低频噪音进行有效隔离的问题，本发明结构合理，降噪效果好，尤其是对中频和中低频噪音有吸隔离效果。
