一种新型组合密封件
本技术属于垃圾处理设备密封
,具体涉及一种新型组合密封件。
技术介绍
垃圾是不被需要或无用的固体、流体物质。在人口密集的大城市,垃圾处理是一个令人头痛的问题。常见的做法是收集后送往堆填区进行填埋处理,或是用焚化炉焚化。在城市生活垃圾处理过程中,将金属物、塑料、纸张、玻璃等进行物资回收、分检出无用的砖瓦和织物进行卫生添埋、分检出的有机物采用微生物堆肥。城市生活垃圾处理设备主要有板链式定量输送机、输送机操作检修台架、筛前输送机等,因有些固体垃圾中参杂有液体,这些垃圾输送设备的密封性显得很重要,为了保证垃圾输送设备的密封性,亟需一种能适用于含水固体的密封件。
技术实现思路
针对上述情况,本技术的目的是提供一种新型组合密封件。通过合理的结构设置,用于垃圾运输设备的轴密封处,在运输过程中对含水固体垃圾进行有效的密封,防止渗滤液的泄露。为实现上述目的,本技术采用如下技术方案:一种新型组合密封件,包括传动轴,所述传动轴沿其传动方向,依次设有一级密封组件、二级密封组件、三级密 ...
