Detailed Description

In order to make the technical solutions of the present invention better understood by those skilled in the art, the present invention is described in further detail below with reference to the accompanying drawings.

As shown in the figure, the gravity type full-house filter comprises a filter body 1, a water source 2 is respectively connected with a water inlet at the upper end of the filter body and an outdoor water storage tank 6 through a pipeline 5, a gate valve 3 and a one-way valve 4, a water outlet at the lower end of the filter body is respectively connected with a household water tank 7 and a roof water tower 8 through pipelines, a floating ball valve 9 is arranged in the roof water tower, the one-way valve 4 is arranged on the pipeline between the water outlet at the lower end of the filter body and the roof water tower, a water outlet at the lower end of the roof water tower is connected with the pipeline between the water outlet at the lower end of the filter body and the roof water tower through the pipeline and the one-way valve, and the other water outlet at the lower end of the roof water tower is connected with an emptying valve 10 through the pipeline; the filter body 1 comprises a box cover 11 and a box body 12, a supporting seat 17 is arranged at the bottom in the box body, a plurality of lifting baskets 18 are arranged in the box body 11, a handle 22 is arranged on each lifting basket, a filter medium layer is arranged in each lifting basket, the filter medium layer sequentially comprises an activated carbon layer 13, a ceramsite layer 14, a smokeless coal layer 15 and a quartz sand layer 16 from top to bottom, a liquid distributor 21 is arranged between the filter medium layers, the liquid distributor comprises a supporting ring 25, an upward convex conical surface 24 is connected to the inner side of the supporting ring, circulation holes 23 which are sequentially increased from inside to outside are arranged on the conical convex surface in an annular mode, the conical convex surface forms a distributor water storage area 19 with the filter medium layer on the upper portion, and the conical convex surface and the filter medium layer on the lower portion form a distributor water outlet area 20.
