Referring to fig. 1 to 3, the embodiment of the present application provides a dtro flow guide plate, which includes a membrane bag and a plate body 1, wherein the membrane bag is used for filtering water. Disk body 1 sets up in the both sides of membrane bag (as shown in fig. 9), 1 both sides of disk body are the plane, the middle part of disk body 1 is provided with water purification collection channel 11, and the both sides of disk body 1 are provided with a plurality of water conservancy diversion posts 2, water conservancy diversion post 2 arranges in order on disk body 1 surface, and water conservancy diversion post 2 is the heliciform and arranges, the water conservancy diversion post 2 that is close to disk body 1 center department more densely arranges, water conservancy diversion post 2 is used for making the rivers that are in disk body 1 surface produce clockwise torrent and anticlockwise torrent. By arranging the flow guide columns 2 in a spiral arrangement on two sides of the tray body 1, when water enters the dtro flow guide tray, due to the flow guide effect of the flow guide columns 2, the water flow generates clockwise spiral turbulence (as shown in fig. 6, lines drawn in the figure are water flow paths) and anticlockwise spiral turbulence (as shown in fig. 7), and under the scouring effect of the two turbulences, dirt attached to the surface of the tray body 1 and the surface of the membrane bag is scoured and washed away by the water flow, like the dirt on the surface of clothes cleaned by a washing machine. Impact membrane bag surface and disk body 1 surface through rotatory torrent, compare in traditional dtro, adopt spiral helicine rotatory torrent can promote the cleaning performance of torrent by a wide margin, and then avoid membrane bag surface pile dirt to influence the filter effect of membrane bag, and then guarantee that the dtro still has good filter effect when lasting the work for a long time.
Referring to fig. 9, in detail, when the dtro works, water to be filtered and purified enters between the tray body 1 and the membrane 3 from the periphery of the diversion tray, the water is filtered and purified through the membrane bags 3, the purified water penetrates through the membrane bags 3 and enters the inner surfaces of the membrane bags 3, the water is guided to the purified water collecting channel 11 by the diversion cloth 4 between the membrane bags 3 for collection, dirty water which is not purified flows into an adjacent purified water chamber through the dirty water channel 15, a sealing ring 5 is arranged between the membrane bags 3 and the tray body 1, the sealing ring 5 is used for separating the dirty water from the purified water, and the sealing ring 5 is arranged around the purified water collecting channel 11. Because be provided with guide post 2 on the disk body 1 to set up helicitic texture 22 on the guide post, and then make when water flows between disk body and membrane bag, receive guide post 2 and surperficial helicitic texture 22's effect and become the torrent, make rivers wash the sanitization with the adnexed dirt in membrane bag 3 surface and disk body 1 surface, and discharge from dirty water passageway 11, and then ensure that the dtro lasts the work for a long time, still have good filter effect.
In one embodiment, the guide post 2 is made of a rust-proof metal material. The water conservancy diversion post 2 that adopts rust-resistant metal material to make compares in the water conservancy diversion post 2 that the tradition adopted the plastics material to make, and water conservancy diversion post 2 that rust-resistant metal material made has the advantage that intensity is high, avoids appearing because of the not enough emergence fracture of 2 intensity of water conservancy diversion posts, and then avoids the fracture scratch membrane bag of water conservancy diversion post 2, protection membrane bag. Meanwhile, the anti-rust metal is adopted, so that the water pollution caused by rusting of the guide column 2 can be avoided. In detail, the diversion column 2 may be made of stainless steel or the like.
Referring to fig. 3 to 4, in one embodiment, the surface of the guide pillar 2 is provided with a thread structure 22, and the top of the guide pillar 2 is provided with a smooth spherical structure 21. Through the surface at flow guide column 2 sets up helicitic texture 22, make the water that is in disk body 1 surface when contacting the helicitic texture 22 on flow guide column 2, the rivers can rotate along helicitic texture 22's helical direction, form local heliciform torrent, cooperate the heliciform range structure of flow guide column 2, the torrent degree of rivers in the further improvement flow guide column, and then make the dirt on membrane bag surface more easily washed by the rivers of torrent and get rid of, and then make the membrane bag can last work for a long time and keep good filter effect. And, be provided with smooth spherical structure 21 at the top of guide post 2, can be so that when guide post 2 contacted the membrane bag, the top of guide post 2 can not scratch and destroy the membrane bag, and then protects the membrane bag, improves the life of membrane bag.
Referring to fig. 7 and 8, in one embodiment, the tray body 1 is manufactured by two-shot molding. The tray body 1 comprises a hardware 13 and an outer injection layer 14 arranged outside the hardware 13. When the tray body 1 is manufactured, firstly, the hardware 13 is manufactured by adopting a stamping forming method, a plurality of through holes (only 4 are drawn in fig. 8 as an indication, and a plurality of actual through holes are provided in the hardware 13), then the guide columns 2 are welded on the hardware 13 according to the arrangement rule of the guide columns 2 in the embodiment, after the guide columns 2 are welded, the parts shown in fig. 8 are placed into an injection mold for injection molding, an external injection molding layer 14 is injected outside the hardware 13, and then the tray body 1 is manufactured. Wherein, the through-hole on hardware 13 can be when moulding plastics, and the layer 14 of moulding plastics in outside can link up the through-hole on hardware 13, and then makes hardware 13 and the outside mould plastics and be connected more firmly between the layer 14. The method for manufacturing the tray body 1 by adopting the secondary injection molding mode solves the problems that glue is not convenient to go, injection molding is difficult and injection molding defects are easy to generate when the tray body 1 is manufactured by adopting the traditional injection molding mode.
In one embodiment, a water producing hole 12 is provided near the clean water collecting channel 11 of the tray body 1.
The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
