Description
Technical field
The utility model belongs to sewage treatment area, particularly relates to shallow media filter.
Background technology
Easily filter amount is discharged by water inlet pipe together along the dirt rinsed out during shallow media filter backwash on existing market, filtrate is caused to need repeatedly to change, the object recycled can not be reached, moreover the captation of prior art mostly is a pipeline, cannot effectively catchment, effect of catchmenting has much room for improvement.
Summary of the invention
The utility model is for the deficiencies in the prior art, and provide a kind of increase filtrate service life and catchment efficient, structure is simply convenient to the shallow media filter installed.
For realizing the utility model object, provide following technical scheme: shallow media filter, comprise spheroidal tank body, the water inlet pipe on tank body top, the outlet pipe of tank body bottom, be arranged at the water-distributing device that in tank body, upper end is connected with water inlet pipe, be arranged at captation that in tank body, lower end is connected with outlet pipe and the filter material layer between water-distributing device and captation, it is characterized in that filter material layer comprises filtrate frame, be arranged at the filtrate on filtrate frame, described filtrate frame bottom is provided with filter screen plate, described filter screen plate one end and filtrate frame hinged, filter screen plate edge is provided with several and connects projection around the center of circle, described projection is arranged O RunddichtringO, described filter screen plate is provided with filter net cloth, the corresponding projection in filtrate frame bottom offers several grooves.
As preferably, tank body is also provided with differential pressure controller.
As preferably, filter screen plate comprises lower flange, and filter net cloth is sandwiched between lower flange, is joined with bolts, and described projection is arranged at upper flange edge.
As preferably, tank body upper right side is provided with manhole.
As preferably, described captation comprise many stainless steel tubes laterally height layout clamp connection straggly to outlet pipe, equidistantly on stainless steel tube cross central line Lower Half pipe outer wall have multiple semicircle arcuation bar shaped water inlet.
The utility model beneficial effect: the utility model substantially prolongs the replacing number of times of filtrate, improve service life, and captation is improved, change the direction that current enter captation, effectively can eliminate eddy flow when catchmenting, more effectively utilize filter course, the rate of filtration is constant simultaneously.
