Description
Technical field
The utility model is related to a kind of sand filter, more particularly to belongs to sewage disposal to streaming continuous sand filter under one kind
The supporting machinery of equipment.
Background technology
Sand filter as a kind of water filtration device, can by the suspended substance removal in water, to reach the purpose of cleaning sewage,
Extensively apply in sewage disposal because of its good filtration effect.Common sand filter generally comprises filtration system and scrubbing system, its
Middle filtration system includes that the sewage inducting tubes that are connected with lauter tub of lauter tub, the sand filter blanket in lauter tub (are piled by sand grains
), the water-locator that is arranged in sand filter blanket and outlet pipe, during filtration, sewage enters water-locator, Jing water-locators from sewage inducting tubes
Into sand filter blanket, and when through sand filter blanket, the pollution impurity in sewage will be left in sand filter blanket, and sewage is changed into clear water by going out
Water pipe is discharged outside lauter tub, and the sand grains in sand filter blanket is then contaminated because of the lower pollution impurity of retention, in order to not affect to filter effect
Really, need to return it into sand filter blanket after cleaning the sand grains for polluting using scrubbing system, washed-out sand water is then outer to be arranged.Common sand
In filter, filter sand backwash process is to stop being carried out under conditions of filtering, and so influences whether the continuity that sand filter runs
With reduction sewage treating efficiency, while backwash can increase flushing device, energy consumption is improved.
Chinese patent Authorization Notice No.：CN201643816, in authorized announcement date on November 24th, 2010, discloses a kind of sand
Filter, including filtration system, filtration system includes lauter tub, sewage inducting tubes, the sand filter blanket in lauter tub and is placed in sand filtration
Water-locator in layer, its weak point is that the filter sand backwash process in this kind of sand filter can not synchronously be carried out with filter process,
And need filtration just to carry out filter sand cleaning after stopping, thus have impact on the continuity of sand filters sewage and reduce sewage
Filter efficiency.
Utility model content
The utility model mainly solves the deficiencies in the prior art, there is provided a kind of compact conformation, filters in sand filter
