the water distribution structure adopts multilayer water distribution, small holes and small-diameter pipelines for water distribution, and the sewage is easy to block when entering the water distribution structure, and the water distributor has a complex structure and high cost.

Disclosure of Invention

Aiming at the problems in the prior art, the utility model aims to provide the water distributor for the filter, which adopts a water distribution concave shell structure, water distribution holes are uniformly formed in the bottom, and when sewage is rapidly introduced into a water inlet pipe orifice, the water can be uniformly sprayed out of the surface of a sand and stone filter layer for filtering along the water distribution holes, so that the water distributor is uniform in water distribution and filtering, simple in mechanism, low in cost and not easy to block.

In order to solve the problems, the utility model adopts the following technical scheme.

The utility model provides a water distributor that filter was used, includes the filter, filter intussuseption is packed the grit filter layer, the concave shell of water distribution is gone into to the inboard card of upper end of filter, the fixed surface of concave shell of water distribution has the apron, the water distribution hole has been seted up to the inboard surface of concave shell of water distribution, the inboard surface fixation of apron has the mouth of pipe that intakes, through adopting the concave shell structure of water distribution, the bottom evenly sets up the water distribution hole, and when the mouth of pipe that intakes was imported sewage fast, can evenly spout a grit filter layer surface filtration along the water distribution hole, and even water distribution filters, and the mechanism is simple, and is with low costs, difficult jam.

Further, the steel wire filter screen plate is placed on the inner side surface of the lower end of the filter, so that a sand filter layer can be supported conveniently, water can be filtered overhead, downward diversion after filtration is facilitated, and a water outlet cannot be blocked.

Further, the lower surface of the steel wire filter screen plate is fixedly provided with supporting legs.

Further, the steel wire filter screen plate supports the sand filter layer in an overhead mode.

Further, a water outlet is arranged on the side face of the filter.

Furthermore, the water distribution holes adopt a round hole structure, and the multi-layer annular arrays are uniformly distributed on the inner side surface of the water distribution concave shell.

Further, the water distribution concave shell and the cover plate are fixed on the upper surface of the filter through bolts.

Compared with the prior art, the utility model has the advantages that:

(1) Through adopting the concave shell structure of water distribution, the bottom evenly sets up the water distribution hole, and when the inlet pipe mouth was imported sewage fast, can evenly spout a grit filter layer surface filtration along the water distribution hole, even water distribution filtration, and the mechanism is simple, and is with low costs, difficult jam.
