一种餐厨垃圾废水处理用多级纳滤装置

Abstract

本实用新型公开了一种餐厨垃圾废水处理用多级纳滤装置，涉及废水处理技术领域。过滤膜工作时，当废水中的固体颗粒随水流冲击膜面时，会在膜孔入口处形成架桥堵塞，从而影响装置的工作效率。本实用新型包括装置主体和换料机构，换料机构设置在装置主体的内部，换料机构包括设置在装置主体内部一端的配件箱。本实用新型通过设置有装置主体、换料机构、过滤筒和驱动柄，通过转动驱动柄，可以带动转动杆进行旋转，通过主动锥齿轮和从动锥齿轮的传输，可以带动丝杆进行转动，使得丝杆外部的螺纹块向下移动，可以带动支撑板随之移动，可以将过滤筒从排水管外部脱离，可以方便将过滤筒取下对内部杂质进行清理，提高了装置的实用性。
