Embodiment
Below in conjunction with accompanying drawing, one exemplary embodiment of the present utility model is explained, to help understanding, they should be thought it is only exemplary comprising the various details of the utility model embodiment.Therefore, those of ordinary skills will be appreciated that, can make various changes and modification to the embodiments described herein, and can not deviate from scope and spirit of the present utility model.Equally, for clarity and conciseness, omitted the description to known function and structure in following description.
In the present embodiment, scribble adhesive waterproof tape (being designated hereinafter simply as " adhesive tape ") between the flow-guiding screen of reverse-osmosis membrane element and reverse osmosis membrane.Can be coated in adhesive tape on flow-guiding screen, then bonding with reverse osmosis membrane, on the contrary also can.Fig. 2 is the schematic diagram according to a kind of mode of the coated tape of the utility model embodiment.
As shown in Figure 2, the flow-guiding screen 20 of deployed condition is rectangular, and an end is fixed with pipe core 21.Pipe core 21 is positioned at the initiating terminal that rolls of flow-guiding screen, rolls direction and is direction from left to right in figure, and is as shown in arrow 24.The one group opposite side parallel with rolling direction is limit 22 and limit 23.Limit 22 whole namely from rolling initiating terminal to rolling the end i.e. limit 25 parallel with pipe core 21, scribble adhesive waterproof tape (as shown in thick black line).The part on limit 23 scribbles adhesive waterproof tape 231, and the part 232 of painting water-proof adhesive band is not as the water outlet that rolls and complete the reverse-osmosis membrane element that obtains after follow-up conventional operation.The profile of this reverse-osmosis membrane element as shown in Figure 3.
Fig. 3 is according to the inside of the utility model embodiment schematic diagram with the lateral inflow reverse-osmosis membrane element of adhesive waterproof tape.Wherein show water outlet 31 and water inlet 32.In fact, namely corresponding to the part 232 of the not painting water-proof adhesive band in Fig. 2, water inlet 32 is corresponding to the limit 25 in Fig. 2 for water outlet 31.
Fig. 4 is according to the inside of the utility model embodiment schematic diagram with the side water outlet reverse-osmosis membrane element of adhesive waterproof tape.Wherein show water outlet 41 and water inlet 42.In fact, namely corresponding to the part 232 of the not painting water-proof adhesive band in Fig. 2, water outlet 41 is corresponding to the limit 25 in Fig. 2 for water inlet 42.
Can find out from Fig. 3 and Fig. 4, this reverse-osmosis membrane element only has three water in-out ports, and institute is simple by water, easy for installation, and has kept the various advantages of lateral flow type reverse-osmosis membrane element, such as roll easily, the film surface velocity is large etc.The film surface velocity is conducive to greatly the settling on fluid scouring film surface and discharges from the waste water mouth, thus be not easy to occur dirty stifled, the life-span that is conducive to improve membrane element.
But it can also be seen that from Fig. 2, the intersection point near zones 26 that limit 22 and pipe core 21 intersects are difficult for having the flow mistake, so the reverse osmosis membrane of this position can not play a role, and that is to say has wasted a part of reverse osmosis membrane.In order to change this situation, in the present embodiment, scribble adhesive waterproof tape 27 in zone 26, to increase near the surface mobility in zone 26, making has the flow mistake herein.The length of adhesive waterproof tape 27 can be 15% to 25% of limit 22 length.
Above-mentioned embodiment does not consist of the restriction to the utility model protection domain.Those skilled in the art should be understood that, depend on design requirements and other factors, various modifications, combination, sub-portfolio can occur and substitute.Any modification of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in the utility model protection domain.
