Description
Technical field
The present invention relates to water purification product technical field, more particularly, to a kind of rolled membrane module.
Background technology
It is that one kind makes filtered fluid by rolled membrane module under a certain pressure using the film process device of rolled membrane module, reaches
Remove the filter of the various contaminant species such as particulate, bacterium in water removal, also commonly referred to as filter core.As shown in Figure 1, 2, at present,
The general structure of rolled membrane module includes central tube 1, the wound membrane being wrapped on central tube 12 and is wrapped in the close of the periphery of wound membrane 2
Sealing cloth 3, wherein, central tube 1 offers multiple collection holes；Wound membrane 2 is mainly made up of filter material film and netted interlayer, its two side ends
Portion surrounds central tube respectively, and forms raw water entrance and concentration water out.During work, raw water enters in wound membrane 2 through raw water entrance,
By being flowed out after netted interlayer from concentration water out, meanwhile, pure water enters central tube 1 in by filter material film and through collecting hole, most
Flowed out eventually from the end of central tube 1.
The rolled membrane module of said structure form, because transversal flow area of the raw water in wound membrane 2 is larger, often leads to
Raw water flow velocity is slower, and the swash of wave effect to filter material film is poor, causes that this rolled membrane module filtering clearance is relatively low, pure water flow velocity
Relatively low and service life is partially short, and user generally requires frequently to change rolled membrane module.
For this reason, it is necessary to be improved to existing rolled membrane module.
The content of the invention
It is an object of the invention to provide a kind of rolled film group for improving filtering clearance, pure water flow velocity and service life
Part.
To achieve these goals, the present invention is adopted the following technical scheme that：
A kind of rolled membrane module, including central tube and at least one set of water purification diaphragm group for being wrapped on central tube；This is net
The two ends of moisture film piece group are respectively formed with raw water entrance and concentrated water outlet, particularly, and the raw water, which enters intraoral be provided with, can stop current
Raw water plugged zone；The cross-sectional area of the raw water plugged zone is less than the cross-sectional area of raw water entrance, raw water plugged zone and original
The raw water passage circulated for raw water is formed between water inlet or raw water plugged zone and central tube；The concentrated water is provided with outlet
The concentrated water plugged zone of current can be stopped；The cross-sectional area of the concentrated water plugged zone is less than the cross-sectional area that concentrated water is exported, concentrated water
The concentrated water passage circulated for concentrated water is formed between plugged zone and concentrated water outlet or concentrated water plugged zone and central tube.
Above-mentioned raw water entrance and concentrated water outlet are formed at the two ends of water purification diaphragm group, and positioned at water purification diaphragm group outermost layer with
Between central tube.
The raw water passage circulated for raw water is formed between above-mentioned raw water plugged zone and raw water entrance and refers to that raw water is blocked
Layer around central tube set and central tube of fitting outermost wall.Because the area of raw water plugged zone is less than the area of raw water entrance,
Raw water passage is formed between raw water plugged zone and raw water entrance immediately.
The raw water passage circulated for raw water is formed between above-mentioned raw water plugged zone and central tube and refers to raw water plugged zone
Around central tube set and water purification diaphragm group of fitting outermost layer.Because the area of raw water plugged zone is less than the face of raw water entrance
Product, is formed with raw water passage immediately between raw water plugged zone and central tube.
The concentrated water passage circulated for concentrated water is formed between above-mentioned concentrated water plugged zone and concentrated water outlet and refers to that concentrated water is blocked
Layer around central tube set and central tube of fitting outermost wall.Because the area of concentrated water plugged zone is less than the area that concentrated water is exported,
Concentrated water passage is formed with immediately between concentrated water plugged zone and concentrated water outlet.
The concentrated water passage circulated for concentrated water is formed between above-mentioned concentrated water plugged zone and central tube and refers to concentrated water plugged zone
Around central tube set and water purification diaphragm group of fitting outermost layer.Because the area of concentrated water plugged zone is less than the face that concentrated water is exported
Product, is formed with concentrated water passage immediately between concentrated water plugged zone and central tube.
The principle of the present invention is as follows：
Because raw water entrance and the concentrated water outlet of this rolled membrane module are respectively arranged with raw water plugged zone and concentrated water plugged zone,
Current can be stopped, so that transversal flow area of the current in wound membrane is reduced, flow direction hair of the raw water inside wound membrane
While changing, flowing velocity of the current inside rolled membrane module is improved, and then make the effect of current scour filter material film
Greatly improve, effectively extend the service life of filter material film, improve the filtering clearance of this rolled membrane module, simultaneously as
The increase of wound membrane water flow inside flow, this can equally make the pure water flow increase that central tube is flowed to through filter material film, make this volume pattern
The speed of component production pure water is greatly promoted.
Raw water plugged zone can be coated in raw water entrance solidify afterwards by glue and be formed, similarly, and concentrated water plugged zone also can be by glue
Concentrated water outlet solidify afterwards are coated in be formed.So, directly it is improved on the basis of existing rolled membrane module, you can obtained
Clearance lifting, the lifting of pure water speed of production and other effects are filtered, cost payout is substantially reduced.
Raw water passage is with concentrated water passage preferably in being staggered in arrangement, i.e., raw water passage is formed at raw water plugged zone and raw water entrance
Between when, concentrated water passage is formed between concentrated water plugged zone and central tube；Raw water passage is formed at raw water plugged zone and central tube
Between when, concentrated water passage be formed at concentrated water plugged zone and concentrated water outlet between.Using above-mentioned design, raw water passage and concentrated water passage
It can respectively stagger, make flow direction of the current in wound membrane change to greatest extent, it is transversal inside wound membrane to reduce raw water
Flow area.
The present invention has the advantages that simple in construction, component filters clearance is high, pure water flow velocity is big, service life is long.
