Description

RO membrane cartridge and cleaning assembly thereof

Technical field

This utility model relates to a kind of water treatment field, more specifically, it relates to a kind of RO membrane cartridge and cleaning assembly thereof.

Background technology

In the process making cleanout fluid, need pure water that the raw material making cleanout fluid is diluted, and the pure water of industrial application is a kind of liquid obtained through multiple times of filtration or distillation, in prior art, it is generally adopted distilled water device and repeatedly distills pure water thus obtaining operable pure water, but the power consumption of this preparation method is relatively big, comparatively wastes the energy.

In prior art, application number is the water purifier that the patent of invention of " 201410062782.1 " discloses a kind of RO film, its pure water by needing in RO film preparation commercial production, owing to it obtains pure water by the method for physics, so its less energy intensive, but in the process of RO membrane cartridge backwash, there is the problem that cannot extract that the negative pressure between RO membrane cartridge is excessive, application number is this back purge system disclosed in the patent of invention of " 201510173836.6 ", disclose this problem at the utility model patent that application number is " 201520049878.4 " simultaneously, it solves in the process of backwash by the mode of air discharge duct, negative pressure between adjacent two reverse osmosis membrane filter elements is excessive, thus causing that adjacent tubes is attracted to the problem that cannot separate together, but air discharge duct have impact on the sealing property of the end face of filter element, particularly liquid to be filtered can be occurred to be mixed in former water in this position, the filter effect causing entirety is deteriorated.

Utility model content

For the deficiency that prior art exists, the purpose of this utility model is in that to provide the convenient RO membrane cartridge separated and cleaning assembly thereof in a kind of good seal performance backwash process simultaneously.

For achieving the above object, this utility model provides following technical scheme: a kind of RO membrane cartridge, including core shell, described core shell is cartridge type, and the two ends of described core shell are provided with lid, and the center of described lid offers centre bore, described lid and core shell are rotationally connected, the position contacted with core shell of described lid is provided with air-vent, is provided with the ft connection of the through hole connected with air-vent, described through hole and core shell in the sidewall of described core shell.

As preferably, described air-vent is with the center circumferentially permutation distribution of lid.

As preferably, described through hole is distributed along the axis circumferentially permutation of core shell.

As preferably, described lid is threadeded with core shell.

A kind of cleaning assembly for RO membrane cartridge, including recoil cask washing and connector, described connector can be fed through centre bore, and the bottom of described connector is provided with the longitudinal section size dividing plate more than centre bore longitudinal section.

As preferably, described connector adopts elastomeric material to make.

By adopting technique scheme, this utility model by being provided with air-vent on the lid of RO membrane cartridge, in core shell, it is provided with the through hole being connected with air-vent simultaneously, simultaneously through hole again with the ft connection of core shell, in use, it is in closed state that lid turns to through hole, does not now have gas permeation, therefore air-tightness is better; When in the process carrying out backwash, lid is by rotating, air-vent position is turned to and is connected with through hole, so that the negative pressure between core shell outer wall and backwash tube is passed by through hole, facilitate the dismounting between RO membrane cartridge and facilitate RO membrane cartridge to extract between backwash tube.

Detailed description of the invention

Referring to figs. 1 through Fig. 5, embodiment of the present utility model is described further.

As shown in Fig. 1, Fig. 3, Fig. 4 and Fig. 5, a kind of RO film 12RO filter element 1RO, including core shell, core shell is cartridge type, is provided with RO film 12RO, RO film 12RO and serves the effect of filtration in the core shell of barrel shape, it is the basic composition of RO film 12RO filter element 1RO, concrete set-up mode and the utility model patent that the concrete structure number of being applied is 201520049878.4 of its operation principle and RO film 12RO are open, and it belongs to prior art, does not repeat at this, the two ends of core shell are provided with lid 11, the center of lid 11 offers centre bore, lid 11 and core shell are rotationally connected, in this utility model, lid 11 is preferably threadeded with the mode that is rotationally connected of core shell, threaded lid 11 and core shell are more accurate when rotating, angle between convenient adjustment air-vent 112 and through hole 113 and position, the position contacted with core shell of lid 11 is provided with air-vent 112, air-vent 112 is through the setting of lid 11, and it is arranged on the position at lid 11 edge, the through hole 113 connected with air-vent 112 it is provided with in the sidewall of core shell, through hole 113 and the ft connection with core shell, thus in use, it is closed state that the relation that lid 11 is threaded connection turns to through hole 113, now do not have gas permeation, therefore air-tightness is better, when comparatively applicable RO film 12RO filter element 1RO is in running order, when in the process carrying out backwash, lid 11 is by rotating, air-vent 112 position is turned to and is connected with through hole 113, so that the negative pressure between core shell outer wall and backwash tube 0 is passed by through hole 113, namely air is inhaled between the inwall of core shell outer wall and backwash tube 0, or air enters between the end face of adjacent two RO film 12RO filter element 1RO, facilitate the dismounting between RO film 12RO filter element 1RO and facilitate RO film 12RO filter element 1RO to extract between backwash tube 0,Simultaneously, as preferably, in order to facilitate lid 11 when rotating, adjust the opening and closing of air-vent 112, and in order to facilitate lid 11 when rotating, by fully on to air-vent 112 and through hole 113, air-vent 112 in this utility model is with the center circumferentially permutation distribution of lid 11, through hole 113 is distributed along the axis circumferentially permutation of core shell simultaneously, the air-vent 112 so arranged adjusts to get up just to be more convenient for through hole 113, the air-vent 112 that will not produce a part is fully on through hole 113, there is again the situation that the air-vent 112 of a part does not turn on through hole 113.

As depicted in figs. 1 and 2, a kind of cleaning assembly of the RO film 12RO filter element 1RO described in claim 1, including recoil cask washing and connector 2, connector 2 can be fed through centre bore, the bottom of connector 2 is provided with the longitudinal section size dividing plate 21 more than centre bore longitudinal section, being simultaneously connected with part 2 adopts elastomeric material to make, such as rubber etc., by multiple RO film 12RO filter element 1RO are set on connector 2, then, backwash multiple RO film 12RO filter element 1RO can be realized, dividing plate 21 serves and prevents the RO film 12RO filter element 1RO problem dropped simultaneously, conveniently extract again, adopt the connector 2 made of elastomeric material to compare the connector 2 of hard simultaneously, avoid connector 2 long in use, the problem that fracture can occur, backwash tube 0 belongs to prior art, its specific works process does not repeat at this.

The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to above-described embodiment, and all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model. It should be pointed out that, for those skilled in the art, without departing from the some improvements and modifications under this utility model principle premise, these improvements and modifications also should be regarded as protection domain of the present utility model.
