Description
Technical field
The present invention relates to water filtration technology fields, more specifically, it relates to a kind of reverse osmosis membrane flow-guiding screen.
Background technique
For RO film water purifier using principle of reverse osmosis, the type of flow of general water is that high concentration, water are flowed to by low concentration
Once, will be from high concentration flow to low concentration after pressurization, that is, so-called reverse osmosis principle.Water conservancy diversion is mostly used between present RO film
Net will separate between two adjacent RO films, and the water for needing to clear up is entered between two RO films by flow-guiding screen, and make water with
RO film comes into full contact with.
Currently, the Chinese invention patent that notification number is CN104353362B opened a kind of water inlet flow-guiding screen, water purification diaphragm group,
Coiled reverse osmosis membrane element and purifier, including the longitudinal rib contacted for side with seperation film in water purification diaphragm group and connection
The dowel of the longitudinal rib；The dowel is located between the plane of the opposite flank of the longitudinal rib, and flat with side
Face interval is opened.
Prior art among the above has the following deficiencies: that cleaning RO film is general by the way of recoil, and water passes through
RO film enters in flow-guiding screen, and the aperture on RO film is smaller, slow with the water flow rate of exchange of flow-guiding screen, to the impact force of flow-guiding screen compared with
It is weak, and dowel is located at the middle position of longitudinal rib thickness direction, and the direction that intakes is parallel with longitudinal rib, so that dowel is to water
The flow resistance of stream increases, and leads to its flows decrease, further reduced the damp impacts to flow-guiding screen, causes flow-guiding screen that can not clean
Completely.
Summary of the invention
It is an object of that present invention to provide a kind of reverse osmosis membrane flow-guiding screen, have the effect of convenient for cleaning.
The present invention to achieve the goals above, provides following technical solution: a kind of reverse osmosis membrane flow-guiding screen, including center
