Novel water filtration device

The utility model provides a novel water filtration device, include the barrel, go up the low head, pass in and out water pipe, blow off pipe, guide plate, cylinder manifold, draft tube, sediment baffle, strain a section of thick bamboo, differential gauge, control system and actuating mechanism for the washing, through the structure that changes inlet tube and outlet pipe to and set up the draft tube, and make solid -state impurity precipitate under the action of gravity, through the wedge filter screen, success separation tiny particle fibre impurity forms twice filter program, utilize the filter screen to replace the filter core, save use cost to the wedge filter screen replaces traditional filter screen, has effectually again prevented that the filter screen from blockking up the harm that causes, the cost -effective while, has improved the filter effect. 本实用新型提供种新型水过滤装置，包括筒体、上下封头、进出水管、排污管、导流板、汇流板、导流筒、沉渣挡板、滤筒、压差计、控制系统及清洗用驱动机构；通过改变进水管与出水管的结构，以及设置导流筒，使得固态杂质在重力作用下沉淀，通过楔形滤网，成功阻隔小颗粒纤维杂质，形成两道过滤程序；利用滤网代替滤芯，节省使用成
