AI Technical Summary
Technical Problem
When existing circular filter cartridges are used in combination, there are problems such as wasted space and uneven pressure distribution, resulting in insufficient utilization of the internal space of the filtration equipment.
Method used
The design incorporates a polygonal filter element with an outer and inner skeleton structure, a corrugated filter layer and a slow-flow backwash space, and guide strips and channels to optimize water flow distribution. Composite materials and sealing design are used to improve stability and filtration efficiency.
Benefits of technology
Within the same volume, it increases the filtration area and efficiency, evens out water flow distribution, extends the lifespan of the filter element, and optimizes space utilization.

Abstract
The utility model discloses a kind of polygon filter element, it is related to filter element technical field, comprising: outer skeleton;The inner sandwich layer and inner skeleton are sequentially arranged from outside to inside along radial direction, the inside and outside of the inner sandwich layer are respectively provided with wave filter layer two and wave filter layer one for filtering water flow, space for slow flow backflushing is arranged between wave filter layer one and wave filter layer two, the upper and lower parts of the outer skeleton and inner skeleton are respectively fixedly connected with upper end cap and lower end cap. By designing multiple rectangular filter elements, it can be closely arranged into an array such as a honeycomb layout, which can increase the filtering area in the same filtering unit volume compared to cylindrical filter elements, improving the filtering efficiency. And the space between wave filter layer one and wave filter layer two is designed, the water flow passing through wave filter layer two enters a large space, thereby temporarily slowing down the water flow pressure, thereby buffering.
