Self-cleaning lamination permeation water purifier

Abstract

The invention discloses a self-cleaning lamination permeation water purifier, comprising a shell and a filter element as well as an inner bushing, wherein the filter element is formed by mutual stacking of at least more than two filtration laminations with center holes, a clearance used for filtering impurities in water is formed between the laminations, the filtration laminations are stacked up in the inner bushing, a pressing plate is arranged at the top end of the inner bushing, criss-cross annular grooves are formed in the surface of the outer circumference of the inner bushing, the annular grooves are communicated with a pure water outlet in the shell, a pressing cap for pressing the pressing plate and the filter element is arranged at the top end of the shell, and a descaling device used for cleaning the filtration lamiantions is arranged in the shell. By adopting the structure, while the water purification effect is ensured, on one hand, installation and dismounting are facilitated due to the inner bushing during installation, and the installation and dismounting efficiency is improved, on the other hand, the structure design is reasonable, the manufacture is easy and convenient, material consumption is reduced compared with conventional water purifiers, and the manufacture cost is lowered.

Description

technical field [0001] The invention relates to a water purifier, in particular to a self-cleaning laminated permeable water purifier. Background technique [0002] Traditional reverse osmosis membrane water purifiers generally include a shell with a reverse osmosis membrane inside. When in use, the device uses a pressure higher than the osmotic pressure as the driving force to separate water molecules and solutes from the water body by using the reverse osmosis membrane. To realize water purification, although the existing reverse osmosis membrane water purifier can realize the water purification function very well, it is expensive, and garbage is easy to accumulate in the housing, which needs to be cleaned regularly, thus limiting its promotion After use, the laminated purifiers that appeared on the market later solved the above problems, but the existing laminated purifiers usually need to use positioning pins to locate the stacked laminates of each sheet. Therefore, ther...
