Description

Filter element Technical Field The application relates to the technical field of filter elements, in particular to a filter element. Background In the technical field of liquid filtration, the filter element is used as a core filter element, and the performance of the filter element is directly related to the efficiency and stability of the whole filtration system. The filter material filled in the filter element is a key element for effectively intercepting and filtering impurities, particles and the like in liquid, and different filter material materials and structures can play a targeted filtering role aiming at specific types of impurities, so that the filtered liquid is ensured to reach the expected purity standard. However, in the existing filter element design and application process, when the liquid continuously flows through the filter element, the filter material in the filter element is very easy to loose, displace, even break and the like due to the comprehensive influence of various factors such as water flow impact, pressure change, self-characteristics of the filter material and the like. Once this occurs, the filter material is easily moved into the water inlet or outlet as the liquid flows. When the filter material gets into the water inlet, can pile up gradually in water inlet department, lead to the through-flow area of water inlet to constantly reduce, and then make the liquid flow who gets into the filter core restricted, influence filtration system's normal feed liquor. Similarly, when the filter material enters the water outlet, the water outlet is blocked, the filtered liquid is prevented from being smoothly discharged, the pressure in the system is increased, the filtering efficiency is reduced, and even the whole filtering system cannot normally operate under severe conditions.
