Description

Technical Field

[0001] The utility model relates to the field of electromechanical equipment, in particular to a disc-type water purification filter element and a water purifier. Background Art

[0002] The household water purifiers with a high market share are mainly based on PVDF hollow fiber membranes. Its advantages are very prominent: high packing density, very large water output, and low price. However, its disadvantages are also obvious: the PVDF membrane made of polymer material has poor anti-pollution performance, is prone to clogging and aging, and the safety of drinking water cannot be absolutely guaranteed.

[0003] The existing household water purifiers with ceramic filter elements are mainly made of diatomaceous earth, which is formed by grouting process and fired at high temperature. The filter element of the water purifier has high mechanical strength, will not break and leak, has large water flux, is cheap, and after the filter element is blocked, it can be manually removed and cleaned by wiping with a scouring pad. However, diatomaceous earth is a high specific surface area material with many micropores arranged neatly on the surface in the shape of a disc or sieve plate. It does not have a regular particle morphology, so it is absolutely impossible to prepare a filter membrane with a narrow pore size distribution through a ceramic sintering process. The main reason for the large water flux and continuous filtration for several hours without obvious attenuation of the water flux is that the filter element pore size distribution is relatively wide, about 0.2 to 1 micron, and the most likely pore size is 0.7 micron. The diameter of the smallest bacteria is about 0.2 microns, so the water purifier cannot absolutely guarantee the biological safety of drinking water.
