Summary of the invention
Technical problem to be solved by this invention be for a kind of can be automatically with absorption saturated with do not adsorb the running water adsorption filter that saturated adsorbing medium separates.
The present invention solves this technical problem the technical scheme that is adopted:
A kind of running water adsorption filter is characterized in that it has a cylindrical shell, the serve as reasons double-decker of tube and urceolus composition of this cylindrical shell, wherein,
The barrel of urceolus is provided with water inlet, and the bottom is provided with discharge gate;
The lower port of inner core extends to the bottom of urceolus, its middle part is provided with the net sheet, this net sheet is separated into two spaces up and down with inner core, wherein, the space on net sheet top is communicated with delivery port, the space of net sheet bottom is for placing the clean water area of proportion less than the adsorbent filtering medium of water, and a charge pipe passes through the barrel of urceolus and extends into described this clean water area.
In above-mentioned technical scheme, fall into what of saturated adsorbent filtering medium of outer tube bottom for the ease of observation, in time it to be got rid of when too much so that gather, described urceolus can be made by transparent material; Further, for the ease of observing the amount of the adsorbent filtering medium in the inner core, so that add adsorbent filtering medium in time, described inner core also can adopt transparent material to make.
Needs according to use occasion, the urceolus in the running water adsorption filter of the present invention and the upper port of inner core can be opened wide, also seal, select the former if allow the running water that filtered flow to a uncovered cistern, if described delivery port directly connects user terminal (as tap) and can select the latter.When selecting the latter, the upper port of described urceolus and inner core can also can seal both upper port with a cover plate simultaneously together respectively with a cover plate for sealing.
In above-mentioned technical scheme, described proportion can be the light material that itself has filtering solid particles and strong adsorption capacity less than the absorption filtering material of water, as the porous cellulose pearls, also can be light material, as polystyrene foam filter pearl with filtering solid particles and easy other adsorbents of load.
A kind of running water adsorption filter of the present invention, during work, running water enters annular space and the past current downflow between inner core and the urceolus from water inlet, flow to the top of net sheet again by the adsorbent filtering medium of lower port in clean water area of inner core, at last by discharging in the delivery port.Because the proportion of described adsorbent filtering medium is less than water, therefore do not adsorb that the particle of all adsorbent filtering mediums all swims in the clean water area of net sheet bottom when saturated, nuisance impurity such as heavy metal ion just is adsorbed on the surface of the particle of described adsorbent filtering medium in the running water.Just deposit to the bottom of urceolus in case the weight behind the particle of some adsorbent filtering medium absorption impurity is during greater than its buoyancy when saturated (adsorb), thereby come with the particle separation of not adsorbing saturated adsorbing medium automatically.Because the particle of the adsorbing medium that absorption is saturated has deposited to the bottom of urceolus, therefore suitably do not adsorb saturated adsorbing medium and can only descend on adsorb saturated adsorbing medium when cutting off the water blowdown, the control blowdown flow rate can will not adsorb saturated adsorbing medium and stay and continue to use.Simultaneously, can be according to an amount of new adsorbing medium, the maintenance adsorption filtration effect of adding of discharge capacity.
