Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 2 to 3, the disc-tube reverse osmosis diversion plate of the present embodiment includes:

the flow deflector comprises a flow deflector body 1, wherein the flow deflector body 1 can be provided with a mounting hole 2 for the central pull rod to pass through, so that a plurality of flow deflector bodies 1 can be passed through by the same central pull rod. The flow guide plate body 1 can be provided with a plurality of mutually independent water production channels 3 which are arranged along the circumferential direction of the mounting hole 2, namely, any two water production channels 3 are mutually isolated. So that permeate entering the inner side of the filter membrane (not shown in the figure) can pass through each water production channel 3, and the filter membrane can be arranged between two adjacent diversion disc bodies. The shape of the water producing channel 3 can be adjusted according to actual needs. Any water producing channel 3 can be isolated from the mounting hole 2, so that a certain preset distance is reserved between any water producing channel 3 and the mounting hole 2, and the problem that the local thickness of the diversion disc is small due to connection between the water producing channel 3 and the mounting hole 2 is solved.

The diversion disc body 1 can be equipped with concentrate groove 6 along circumference ring, and concentrate groove 6 is used for discharging the concentrate after the filtration membrane that will flow through. One side of flow guide plate body 1 can be including being located thick liquid groove 6 inboard and along axially extended bellying 7, the part that the opposite side of flow guide plate body 1 is located thick liquid inslot side can be sunken along the axial for other parts, sealing washer groove 8 can encircle the outside of establishing the part at bellying 7 and thick liquid inslot side, sealing washer groove 8 can be provided with the sealing washer, thereby can be with the concentrate in the thick liquid groove 6 of flowing through and the permeate through liquid of producing water passageway 3 of flowing through mutual isolation, prevent permeate through liquid and concentrate remixing.

In this embodiment, after installation to the disc-tube reverse osmosis apparatus, the outside of the seal ring groove 8 is high-concentration sewage to be treated, i.e., a concentrated solution. The concentrated solution rapidly flows through each layer of filter membrane under the flow guiding effect of the flow guiding disc body 1, then turns reversely by 180 degrees and reaches the other surface of the filter membrane, thereby flowing through each filter membrane layer by layer. While the concentrated solution flows through the filter membrane, the permeate enters the inner side of the membrane and is discharged out of the disc-tube type reverse osmosis device through the water production channel 3 according to the reverse osmosis principle due to the internal and external pressure of the membrane. The filtered concentrated solution is discharged out of the disc tube type reverse osmosis device through a concentrated solution tank 6.

Borrow by above-mentioned structure, through seting up mutually independent between the water production passageway 3 on the flow guide plate body 1 for permeate liquid can pass through along the water production passageway 3 on the flow guide plate body 1, thereby leads to the shape of flow guide plate body 1 continuous, can prevent to appear the region of stress concentration when permeate liquid passes through water production passageway 3.

The pressure of the permeation liquid acting on the diversion disc body 1 is uniform in the process of passing through the water production channel 3, so that the overall strength of the diversion disc body 1 can be improved, and the diversion disc body 1 is prevented from cracking due to nonuniform stress.

Specifically, as shown in fig. 2 and 3, the radius of each water producing channel 3 may be the same. That is, in the present embodiment, the respective water producing channels 3 are circular in the same size. Thereby further make the pressure that acts on the flow guide plate body 1 more even, further promote the bulk strength of flow guide plate body 1.

Specifically, as shown in fig. 2 and 3, the mounting hole 2 may be circular and disposed at the center of the diaphragm body 1, so that after the central tie rod passes through the diaphragm body 1, the central tie rod is located in the central area of the diaphragm. So that the concentrated liquid can flow uniformly in the process of flowing through the flow guide disc. The plurality of water producing channels 3 may be arranged around the mounting hole 2, i.e. the plurality of water producing channels 3 may have the same centre as the mounting hole 2. Thereby make permeate liquid can flow evenly around the mounting hole 2 when producing water passageway 3, can further promote the continuity of whole guiding disk body 1 shape to promote the stability of dish tubular reverse osmosis guiding disk in the use.

Specifically, as shown in fig. 2 and 3, the water producing passages 3 may be arranged at equal intervals, so that in the using process, the acting force applied to the diversion disc body 1 by the permeating liquid received by the diversion disc body 1 is uniform, and the diversion disc body 1 is prevented from cracking due to nonuniform stress.

Specifically, as shown in fig. 2, the outward flange of flow guide disc body 1 can include along the spacing portion 4 of the axial extension of flow guide disc body 1, and when the center pull rod was worn to establish on a plurality of flow guide disc bodies 1, spacing portion 4 of adjacent flow guide disc body 1 can butt each other to can separate the space of spacing portion 4 both sides, prevent that the concentrate of spacing portion 4 both sides from contacting each other, thereby promote the effect of reverse osmosis. The cross-sectional shape of the limiting portion 4 may be circular, that is, the cross-sectional shape of the outer edge of the diaphragm body 1 is circular. Thereby reducing the resistance experienced by the concentrate during flow.

Specifically, as shown in fig. 2 and 3, two sides of the diaphragm body 1 may be provided with bumps 5, and a flow channel may be formed between the bumps 5. The salient points 5 can form a flow passage radiating from the center of the flow guide disc body 1 to the edge, so that the concentrated solution can move in the flow passage and form turbulent flow.

Specifically, as shown in fig. 2 and 3, a protruding portion 9 protruding in the axial direction of the diversion disc body 1 may be disposed on one side of the diversion disc body 1, a positioning portion 10 corresponding to the protruding portion 9 may be disposed on the other end of the diversion disc body 1, and the protruding portion 9 may be inserted into the positioning portion 10 to connect adjacent diversion disc bodies 1. After the protrusion 9 is inserted into the insertion portion, the adjacent deflector bodies 1 are prevented from sliding relatively, so that the concentrated solution in the flow passage can flow uniformly.
