Description

Filter element mounting structure and water purification system thereof

Technical Field

Background

The water purifying system is a water treatment system for carrying out deep filtration and purification treatment on water quality according to the use requirement of water. The water purifying system is arranged on the market, and besides the water purifying machine with the filtering function, the water purifying machine also comprises a water purifying machine integrating the filtering, heating and/or refrigerating functions, a bubble water machine integrating the filtering and the inflating functions, and the like. The filter element is a core component of the water purification system, and common filter elements comprise a PP cotton filter element, an active carbon filter element, an ultrafiltration membrane and a reverse osmosis membrane. The PP cotton filter core is mainly used for intercepting large-particle impurities such as sediment, rust and the like. The active carbon filter core is mainly used for adsorbing residual chlorine and peculiar smell with different colors, and can improve the taste. The ultrafiltration membrane has a minimum diameter of 0.01 μm and can filter macromolecular substances such as viruses and bacteria, but has no filtering effect on small molecular substances such as ions, heavy metals, pesticide agents and the like which are soluble in water. The minimum filtration diameter of the reverse osmosis membrane is 0.0001 μm, and all substances in water can be filtered out basically. Wherein, reverse osmosis membrane becomes the main filter core of water purification unit gradually because of its high accuracy filter effect.

After the water purification system is used for a long time, impurities in water can be adhered to the water passing component and the inner wall of the pipeline, wherein the impurities are accumulated in the filter element to the greatest extent, so that the water safety can be influenced, and the filtering capacity of the filter element can be greatly reduced. Therefore, the waterway and the filter element of the water purifying system need to be washed regularly, and even the filter element needs to be replaced regularly.

The flushing principle of the existing water purifying system is as follows: the water inlet end of the waterway is fed with water and is discharged through the water pump, the filter element and the waste water valve in sequence. Because the waste water valve is connected to the waste water outlet pipeline of the filter element, the flushing mode can only flush the water component and the corresponding waterway at the upstream of the reverse osmosis membrane filter element, and cannot flush the water component and the corresponding waterway at the downstream of the reverse osmosis membrane filter element, namely cannot flush all waterways.
