Embodiment
Below in conjunction with accompanying drawing of the present utility model, clear, complete description is carried out to the technical solution of the utility model,
Obviously, described embodiment is only the utility model part of the embodiment, rather than whole embodiments.It is new based on this practicality
Embodiment in type, the every other reality that those of ordinary skill in the art are obtained on the premise of creative work is not made
Example is applied, belongs to the scope of protection of the utility model.
As shown in figure 1, a kind of shallow-sand filter, including spherical filter cylinder 1, the spherical inwall of filter cylinder 1 gather provided with black
Pvdf layer 3, the spherical shell of filter cylinder 1 are stainless steel layer 2, and water inlet pipe, cloth are from top to bottom sequentially provided with the spherical filter cylinder 1
Hydrophone 7, filter material layer, collecting system 14 and outlet pipe.
The water inlet and the junction of pressurized water tubes 4 are provided with sealing device 5, and the pressurized water tubes 4 are provided with differential pressure control
Device 6 processed, the water-locator 7 are located at the top in spherical filter cylinder 1, and the filter material layer is from top to bottom followed successively by garnet layer 9, PP cottons
Layer 10, degerming film layer 11, active carbon layer 12 and support layer 13, the collecting system 14 include multiple equally distributed water collectors,
The water collector is pressure-compensated water collector.Filter bottom is provided with multiple equally distributed water collectors, by the water after filtering
Equably collect and draw, advection filtering, filter can be made to be filtered under high flow rate, still can reach the effect preferably filtered.
The collecting system 14 is connected with outlet pipe, and the spherical bottom of filter cylinder 1 is provided with delivery port 15, the outlet pipe with
Delivery port 15 connects, and the top of the spherical filter cylinder 1 and side wall are equipped with service ports 8, and the service ports 8 are provided with folding lid,
The folding lid is provided with handle, and the spherical filter cylinder 1 is located on support, and the frame bottom is provided with dismountable three uniformly
The supporting leg of distribution, the supporting leg bottom are provided with vapor barrier.
The garnet layer 9, PP cottons layer 10, degerming film layer 11, the packed height of active carbon layer 12 and support layer 13 difference
For 200mm, 150mm, 80mm, 300mm and 500mm.The particle diameter of the garnet and activated carbon be respectively 10-20 mesh and 30-
