Description
Technical field
The utility model relates to a kind of reverse osmosis membrane filter elements, belong to purification of water quality processing technology field.
Background technique
Reverse osmosis membrane filter element is made of the reverse osmosis membrane of central tube and winding, and pure water channel is provided in central tube,
The wall of diaphragm forms concentrated water channel, and pipe surface design in center has the multiple pure water through-hole confluences of axially spaced distribution at pure water
Concentrate channel.Conventional reverse osmosis membrane filter is from along axial one end, into raw water, the other end exports concentrated water, so that water inlet circulation
Road is only from water inlet end to the axial distance at concentrated water end, and water stream channel is shorter, and water use efficiency is lower.There are also reverse osmosis membrane filter elements
Water inlet and concentrated water are separated by sealing ring, as the working time of reverse osmosis membrane filter element extends the fluctuation with pressure before film, meeting
It is easy to appear sealing ring into water and concentrated water mutually to gang up to form " channelling " effect, causes the easy heap of the pollutant on reverse osmosis membrane surface
Product causes the service life of reverse osmosis membrane short so that salt rejection rate and water yield reduce.
Application No. is 201621251903.8 Chinese utility model is special filed in the applicant on November 15th, 2016
Benefit discloses a kind of reverse osmosis membrane filt, by between the installation center pipe in RO film, with putamina upper cover, RO film upper surface
Intake antrum in the raw water communicated with raw water interface is formed, RO film lower cover and putamina bottom, RO film form raw water between lower end surface
Lower intake antrum.Realization is intake simultaneously from the upper surface of RO film and lower end surface two sides, is increased the water velocity of film surface, is increased
The contact area of raw water and RO film, compared to the rate of recovery that conventional reverse osmosis membrane filter improves pure water.But it sends out in use
Existing, flow velocity is slower during raw water is filtered into water purification by intake antrum under raw water, and RO film still has the phenomenon that crystalline deposit, filtering
Effect needs to be further increased.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of reverse osmosis membrane filter elements, can be improved central tube bottom
Portion enters the flow velocity of the raw water of reverse osmosis membrane assembly lower end surface, reduces the crystalline deposit of reverse osmosis membrane assembly, prevents diaphragm from blocking.
To solve the above-mentioned problems, the technical solution adopted in the utility model is as follows:
A kind of reverse osmosis membrane filter element including filter case, end cover of filter element, hollow central tube, is wrapped on central tube
Reverse osmosis membrane assembly, upper end cover, lower end cover, the top of the end cover of filter element open up raw water interface, water purification mouth and dense
The mouth of a river,
The upper end cover, lower end cover are mounted between the upper and lower end of reverse osmosis membrane assembly and filter case, institute
It states and intakes in the raw water for being formed between the upper surface of end cover and end cover of filter element, reverse osmosis membrane assembly and being communicated with raw water interface
Chamber, lower end cover and filter case bottom, reverse osmosis membrane assembly lower end surface between formed raw water under intake antrum,
The bottom end of central tube passes through reverse osmosis membrane assembly and protrudes into intake antrum under raw water, has demarcation plate in central tube, will in
The water purification water chamber and central tube intake antrum with the perforation of water purification mouth are divided into inside heart pipe, the upper end of the central tube has difference
The raw water inlet to connect with intake antrum in raw water and central tube intake antrum offers several pure water on the outer wall of central tube
Collecting tank, the pure water collection slot are communicated with positioned at central tube top and with the water purification mouth of water purification water chamber perforation,
The bottom of the filter case offers the second raw water inlet.
Further, the reverse osmosis membrane assembly is the reverse osmosis membrane wound on center pipe surface.
Further, the pure water collection slot collects by several annular collecting vats opened up along center pipe outer wall and with all annulars
Longitudinal catch basin composition that sink communicates.Raw water enters annular collecting vat after purifying by reverse osmosis membrane, then is catchmented by annular
Slot flows into pure water collection mouth, subsequently enters water purification water chamber, most flows out afterwards through water purification mouth.
Further, the longitudinal section shape of the demarcation plate is zigzag.
Further, the upper end cover, lower end cover are pasted by glue adhesive and reverse osmosis membrane assembly.
Compared with prior art, the utility model has the beneficial effects that: the second raw water that the bottom of filter case opens up
Water inlet is accelerated the flow velocity for entering the raw water of intake antrum under raw water, is prevented by the raw water flowed into from the second raw water inlet
Because the precipitated crystal of reverse osmosis membrane extends reverse osmosis to reduce the pollution speed of reverse osmosis membrane caused by flow velocity is lower
The service life of diaphragm, improves water use efficiency.Concentrated water is flowed out from the outside of reverse osmosis membrane, is pooled to the discharge of concentrated water interface.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of one preferred embodiment of the utility model.
Fig. 2 is the structural schematic diagram of the central tube of the utility model.
Specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It is said according to following
