Plate-type laminated composite membrane filter core

Abstract

The invention discloses a plate-type laminated composite membrane filter core which is characterized by including a casing with a raw water inlet and a clean water outlet, a filter core is arranged inside the casing, a filter membrane core is arranged on the top of the filter core, the filter core comprises a plurality of layers of active carbon filter cores and PP (propene polymer) cotton filter cores, upper and lower positions of the plurality of layers of the active carbon filter cores and the PP (propene polymer) cotton filter cores are adjustable, the PP cotton filter cores are plate-type filter cores, the outer edges of the active carbon filter cores and the PP cotton filter cores are tightly attached to the inner wall of the casing, and the filter membrane core is a nano filter membrane core. The advantages of the plate-type laminated composite membrane filter core are that: the filtering effect is good, the space occupying area is small, production and use costs are low.

Description

[0001] technical field [0002] The invention relates to a plate-type laminated composite membrane filter element, which belongs to the field of accessories of water purification devices. Background technique [0003] With the continuous improvement of people's living standards, the awareness of drinking water health has been continuously strengthened, and more and more people have begun to drink purified water. Traditional water purification filters are generally composed of multi-stage filter cartridges. According to the different requirements of the purification function, filter elements with corresponding filtering functions are installed in each stage of filter cartridges. The water filter composed in this way not only has a large installation space, but also consumes raw materials for the finished product. There are many, and because there are many types of water purification devices, the filter materials, structures and filtration methods used are not the same. Th...

Traditional water purification filters are generally composed of multi-stage filter cartridges. According to the different requirements of the purification function, filter elements with corresponding filtering functions are installed in each stage of filter cartridges. The water filter composed in this way not only has a large installation space, but also consumes raw materials for the finished product. There are many, and because there are many types of water purification devices, the filter materials, structures and filtration methods used are not the same. These factors will affect the quality of drinking water and purified water, and then affect people's drinking water health; , the sealing effect between the filter element and the shell is not good, causing the raw water to flow through the gap between the filter element and the shell, which cannot be filtered effectively, and cannot guarantee the drinking water health of the drinker; moreover, the traditional water purification device adopts It is a cylindrical PP filter element with a cylindrical water flow channel in the middle. This structural design makes the water purification device larger in size, inconvenient for transportation and installation, and has a small water filtration area. In addition, this sleeve-type PP cotton filter element once After the production is completed, its structural shape is difficult to change, and it cannot adapt to the raw water quality of different cleanliness
