Abstract
The utility model discloses a spiral wound module center tube structure, sleeve pipe in the center, center outer tube and reverse osmosis membrane, there is annular circulation clearance in the center between sleeve pipe and the central outer tube, it is equipped with a plurality of gully -holes to follow the axial interval at central outer tube lateral wall, sleeve pipe and central outer tube top sealing connection in the center, among this spiral wound module center tube structure, adopt the structural style of interior sleeve pipe in center and the combination of central outer tube suit, circulate the clearance with the annular and regard as pure water circulation pipeline, regard central endotheca intraductal chamber as raw water circulation pipeline, the raw water is sleeve pipe from bottom flow direction top in the center, it purifies to permeate reverse osmosis membrane downwards from the top again, the pure water that obtains flows out downwards through getting into annular circulation clearance again, so make filter core water inlet, pure water outlet and wastewater outlet can both integrate in one end, simplify filter core water route tube coupling effectively for whole filter core structure is more compact.
Description
Technical field
This utility model relates to coiled reverse osmosis membrane filter cartridge construction, particularly to a kind of rolled membrane module center tube structure.
Background technology
Reverse osmosis membrane filter element is purifying water process filter element conventional in existing water purifier, existing reverse osmosis membrane filter element, usual former water be from one end of rolled membrane module flow into, along rolled membrane module axially across former water flow passage, flowing out from the other end of rolled membrane module, the water of outflow is condensed water again；Current are during former water flow passage, and a part of water flows into through reverse osmosis membrane and produces in water flow passage, flow to central canal being wound around the direction of central canal, finally flow out from one end of central canal in producing water flow passage.
In the rolled membrane module of this kind of version, its water inlet is arranged on one end, wastewater outlet and pure water outlet are then arranged on the other end, this has resulted in inlet pipeline and outlet pipeline is respectively at filter element two ends, make filter element water route pipeline connect complexity, cause filter element bulky, wherein, central canal, as just the circulation duct of pure water, fails to be fully utilized.
Utility model content
The rolled membrane module center tube structure that technical problem to be solved in the utility model is to provide a kind of compact conformation, water collection efficiency is high
By solving the technical scheme that above-mentioned technical problem is used: a kind of rolled membrane module center tube structure, the center trocar sheath that including center inner sleeve, is sleeved on outside the inner sleeve of center and be wound on the reverse osmosis membrane outside the trocar sheath of center, annular flow gap is there is between described center inner sleeve and center trocar sheath, being provided with multiple gully-hole described center trocar sheath sidewall is axially spaced, described center inner sleeve is connected with the end sealing of center trocar sheath.
Further, between each described gully-hole, spacing distance is gradually reduced to bottom from top.
Further, described center inner sleeve is one-body molded with the top of center trocar sheath is connected.
Beneficial effect: in this rolled membrane module center tube structure, the center tube structure form of abandoning tradition, employing center inner sleeve and the version of center trocar sheath combined set, is threaded a pipe as stream of pure water in annular flow gap between the two, center inner sleeve inner chamber is threaded a pipe as former current, Yuan Shuijing center inner sleeve flows to top from bottom, penetrate down into reverse osmosis membrane from top again to purify, the pure water obtained enters annular flow gap through center trocar sheath and flows out still further below, so central canal of version makes filter element water inlet, pure water outlet and wastewater outlet can be integrated in one end, effectively simplify filter element water route pipeline to connect, make whole filter cartridge construction the compactest.
Accompanying drawing explanation
With embodiment, this utility model is described further below in conjunction with the accompanying drawings；
Fig. 1 is the structural representation of this utility model embodiment；
Fig. 2 is the partial structurtes schematic diagram of the center trocar sheath in this utility model embodiment.
Detailed description of the invention
See figures.1.and.2, this utility model one rolled membrane module center tube structure, the center trocar sheath 2 that including center inner sleeve 1, is sleeved on outside center inner sleeve 1 and be wound on the reverse osmosis membrane 3 outside center trocar sheath 2, annular flow gap 4 is there is between center inner sleeve 1 and center trocar sheath 2, being provided with multiple gully-hole 5 center trocar sheath 2 sidewall is axially spaced, center inner sleeve 1 is connected with center trocar sheath 2 end sealing.
In the present embodiment, center inner sleeve 1 is formed in one with the top of center trocar sheath 2 and is connected, i.e. current are only possible to the gully-hole 5 from center trocar sheath 2 and flow in annular flow gap 4, wherein, Yuan Shuijing center inner sleeve 1 flows to top and radially outward flows out from bottom, penetrating into reverse osmosis membrane 3 the most again to purify from top to bottom, a portion water passes through reverse osmosis membrane in gully-hole 5 enters annular flow gap 4 as pure water, and another part water is discharged as waste water from reverse osmosis membrane bottom.The center tube structure form of this utility model center tube structure abandoning tradition, employing center inner sleeve and the version of center trocar sheath combined set, the outlet of filter element water inlet, pure water and wastewater outlet can be made can be integrated in one end, effectively simplify filter element water route pipeline to connect so that whole filter cartridge construction is the compactest.
Wherein, when flowing through reverse osmosis membrane 3 from top to bottom due to former water, its resistance constantly increases, the pure water collected through gully-hole 5 through reverse osmosis membrane tapers into, as preferably, between each gully-hole 5 on center trocar sheath 2, spacing distance is gradually reduced to bottom from top, is so effectively improved pure water water collection efficiency.
Above in conjunction with accompanying drawing, embodiment of the present utility model is explained in detail, but this utility model is not limited to above-mentioned embodiment, in the ken that described technical field those of ordinary skill is possessed, it is also possible on the premise of without departing from this utility model objective, various changes can be made.
Claims (3)
1. a rolled membrane module center tube structure, it is characterized in that: the center trocar sheath that include center inner sleeve, is sleeved on outside the inner sleeve of center and be wound on the reverse osmosis membrane outside the trocar sheath of center, annular flow gap is there is between described center inner sleeve and center trocar sheath, being provided with multiple gully-hole described center trocar sheath sidewall is axially spaced, described center inner sleeve is connected with the end sealing of center trocar sheath.
Rolled membrane module center tube structure the most according to claim 1, it is characterised in that: between each described gully-hole, spacing distance is gradually reduced to bottom from top.
