Filter element assembly and water purifying device with same

Abstract

The invention discloses a filter element assembly and a water purifying device with the same. The filter element assembly comprises multi-group filter elements connected in series, wherein each filter element group comprises a plurality of filter elements connected in parallel; the water purifying device comprises the filter element component, a membrane filter element, a concentrated water pipe and a pure water pipe; the uppermost filter element in the filter element assembly is suitable for being connected with a water source; the inlet of the membrane filter element is connected with the outlet of the filter element assembly; the membrane filter element is further provided with a pure water outlet and a concentrated water outlet; the concentrated water pipe is connected with the concentrated water outlet, and the pure water pipe is connected with the pure water outlet. According to the filter element assembly disclosed by the invention, the filter element groups are formed through the parallel connection of the plurality of same filter elements, the water purifying flux and the water purifying amount of the water purifying device are increased in a mode of connecting the plurality of filter element groups in series, the flux of the water purifying device and the stability of the service life of the filter element are guaranteed, and the large flux requirement of a apparatus is satisfied.

Description

technical field [0001] The invention relates to the field of water purification equipment, in particular to a filter element assembly used in a water purification device and a water purification device with the same. Background technique [0002] In the related art, the filter element components of the water purification device are mostly composed of a single filter element connected in series. The disadvantage of this is that the amount of purified water is small, which cannot meet the requirements of the large throughput of the equipment, and at the same time, the amount of purified water will decrease after the equipment is used for a long time. problem; in the related art, there is also a filter element assembly of a water purification device that is formed by connecting multiple filter elements in series and then in parallel. Different types of filter elements have different filtering capabilities, which makes this filter element assembly unable to give full play to the...

[0002] In the related art, the filter element components of the water purification device are mostly composed of a single filter element connected in series. The disadvantage of this is that the amount of purified water is small, which cannot meet the requirements of the large throughput of the equipment, and at the same time, the amount of purified water will decrease after the equipment is used for a long time. problem; in the related art, there is also a filter element assembly of a water purification device that is formed by connecting multiple filter elements in series and then in parallel. Different types of filter elements have different filtering capabilities, which makes this filter element assembly unable to give full play to the filtering capabilities of different types of filter elements, and also cannot meet the high-flux requirements of the equipment, and there will also be differences in the clean water flux and the life cycle of the filter element. stability problem
