The filter element is generally used in oil filtration, water filtration, air filtration and other filtration industries to remove a small amount of impurities in the filter medium to protect the normal operation of the equipment or the cleanliness of the air. When the fluid passes through the filter element with a certain precision in the filter, its impurities are blocked, and the clean fluid flows out through the filter element. When the existing multi-stage filter element is in use, it is difficult to clean the particles and foreign matter attached to the surface of the filter element, which affects the filtration efficiency and service life of the filter element. In addition, the filter element is not easy to replace and is easy to be contaminated and waste liquid overflows. In view of the existing problems, it is necessary to set a multi-stage filter element with high surface cleanliness, good replacement convenience and less waste liquid overflow.
