Specific embodiment

To keep the above objects, features, and advantages of the utility model more obvious and easy to understand, with reference to the accompanying drawing to this The specific embodiment of utility model is described in detail.

Fig. 2 and Fig. 3 are please referred to, the utility model provides a kind of reverse osmosis membrane, is placed on flow guiding disc, the water conservancy diversion Disk is radially respectively arranged with flow guiding disc tie rod hole 400, disc core 500, the waste water mistake for water conservancy diversion waste water from center from inside to outside Hole and reverse osmosis region, the reverse osmosis membrane center offer the diaphragm tie rod hole 100 passed through for pull rod, the diaphragm pull rod Notch 200, the region where disc core 500 on the corresponding flow guiding disc of the notch 200 are uniformly provided on 100 circumference of hole.

Specifically, the notch 200 be symmetrical arranged there are four or six or eight, the principle of design is to allow as far as possible Diaphragm tie rod hole 100 forms fillet polygon, so the number of edges of fillet polygon is greater than 2 less than 10 as far as possible, that is to say, that notch 200 number is more, flows out from notch 200 convenient for water, but the number of notch 200 cannot be excessive, avoids fillet polygon close Like being circle, to expand the radius of diaphragm tie rod hole 100, lead to its more difficult fitting pull rod.

In the present embodiment, preferably four, the shape of rounded square is formed with diaphragm tie rod hole 100.It is each described Corresponding arc section 220 of the notch 200 by arc-shaped edges 210 and the arc-shaped edges 210 on the circumference of the diaphragm tie rod hole 100 Both ends connect composition, and the corresponding center of circle of the arc-shaped edges 210 is different with 100 center of circle of diaphragm tie rod hole, and arc-shaped edges 210 are corresponding Central angle can be optional, preferably, the corresponding central angle of arc-shaped edges 210 is about 180 ° or so.

The reverse osmosis membrane on piece, which is also provided with, to be produced water and portals 300, and for assisting water outlet, all production water, which portals, 300 to be enclosed It is uniformly distributed, and is distributed between two neighboring notch 200 around the diaphragm tie rod hole 100.

Portal 300 preferably, being arranged with several between two neighboring notch 200 and producing water, orientation is one and lacks Mouth 200 extends between another adjacent notch 200.In the present embodiment, since there are four notch 200, diaphragm pull rods for tool Hole 100 forms rounded square, therefore it 300 is along rounded square that the production water between two neighboring notch 200, which portals, A line arrangement in the present embodiment, arranges three production water and portals 300 between two neighboring notch 200.

Preferably, it is described produce water and portal 300 also correspond to region where disc core 500 on the flow guiding disc.

Specifically, the disc core 500 of flow guiding disc corresponding to the present embodiment is as shown in figure 3, be only arranged two together in disc core 500 The axial projection annulus of axis, from inside to outside respectively inner bulge annulus 510 and outside protruding circular ring 520, two axial projections The groove formed between annulus is placed with sealing ring, that is to say, that in inside protruding circular ring 510 and flow guiding disc tie rod hole 400 it Between be not provided with any axial raised structure, the corresponding inner bulge annulus 510 of the notch 200 and the flow guiding disc pull rod The region is defined as water purification guide groove 530 by the region between hole 400, it is same produce water and portal 300 also correspond to water purification guide groove 530, guarantor The water energy in region between card inner bulge annulus 510 and flow guiding disc tie rod hole 400 is enough from notch 200 and to be produced water and portals 300 Place's outflow.

Preferably, the structure in two faces of the flow guiding disc is symmetrical, so that on two faces of flow guiding disc Reverse osmosis membrane chip architecture is consistent, without the diaphragm that front and back sides are specially arranged.

Using reverse osmosis membrane provided by the utility model, for, in addition to seal groove, being not provided with any in disc core 500 Axial raised flow guiding disc when being assembled using above-mentioned reverse osmosis membrane with it, reverse osmosis membrane is set in and is drawn across flow guiding disc On the pull rod of rod aperture 400, the place of non-notch 200 is contacted with pull rod on diaphragm tie rod hole 100, and the water in disc core 500 is from notch 200 It flows out in place, that is to say, that reverse osmosis membrane radial positioning provided by the utility model is by intact on diaphragm tie rod hole 100 200 place of mouth is contacted with pull rod, and water conservancy diversion water is by the notch 200 around diaphragm tie rod hole 100, and there is no need to by flow guiding disc Setting axial projection to carry out radial positioning to reverse osmosis membrane, simplifies the structure of dish periosteum component, improves production and group Fill efficiency.

Obviously, it is practical new without departing from this can to carry out various modification and variations to utility model by those skilled in the art The spirit and scope of type.If these modifications and variations of the present invention belong to the claims of the present invention and its equivalent technology Within the scope of, then the utility model is also intended to including these modification and variations.
