Because the hollow fiber RO membrane is integrated by a large amount of hollow fibers, all water flows into the hollow fibers to play a filtering role, but the traditional water inlet adopts a concentrated water inlet to lead to uneven water inlet of the RO membrane, the water inlet of the middle lower part is large, the water inlet of the upper part is small, the application efficiency of the RO membrane is lower, and the maximum advantage of the RO membrane cannot be exerted.

Disclosure of Invention

In view of the above, the utility model aims to provide a deflector suitable for a hollow fiber RO membrane, so as to solve the problems that the prior water inlet adopts a concentrated water inlet, so that the RO membrane is uneven in water inlet, large in water inlet at the middle and lower parts, small in water inlet at the upper part, low in application efficiency of the RO membrane and incapable of exerting the maximum advantages of the RO membrane.

In order to achieve the above purpose, the present utility model adopts the following technical scheme: the utility model provides a guide plate suitable for hollow fiber RO membrane is used, includes guide plate body, water inlet, a plurality of guiding gutter, air inlet and a plurality of splitter box, the center of guide plate body is provided with the water inlet, the water inlet periphery is provided with a plurality of round ring guiding gutter, a plurality of splitter boxes of water inlet periphery intercommunication, guiding gutter and splitter box intercommunication, the below of guiding gutter is provided with the air inlet.

Still further, the guide plate suitable for hollow fiber RO membrane is used still includes the seal groove, guide plate body is provided with the seal groove all around.

Further, the seal groove is provided with a sealing piece for sealing the guide plate and the membrane shell

Furthermore, the cross section of the diversion trench is triangular, the bottom surface is narrow, and the upper surface is wide.

Furthermore, the diversion trenches are used for dispersing water flow, so that the water flow is uniformly distributed into the hollow fiber RO membrane.

Furthermore, the number of the shunt grooves is 4, and the included angle between two adjacent shunt grooves is 90 degrees.

Compared with the prior art, the guide plate for the hollow fiber RO membrane has the beneficial effects that:

the utility model provides a guide plate suitable for a hollow fiber RO membrane, which is characterized in that after water enters a water inlet, water flow is uniformly dispersed by a plurality of guide grooves arranged on the guide plate, so that each hollow fiber can uniformly enter water, and the utilization rate of the RO membrane is improved.
