Description
Technical field
The utility model relates to the drink water purifying technical field, refers in particular to the combined type filter core that a kind of water purifier is used.
Background technology
In order to remove various poisonous and harmful substances in the former water effectively, the special water purifier for drinking machine filter cartridge construction has been variation now.As press water flow mode classification, a class be current filter from top to bottom flow type filter element falls, another kind of is current up-flow filter cores from bottom to top, also having a class is that existing up-flow has the hybrid filter core that falls stream again.
Falling flow type filter element, to go out hydrodynamic force bigger, but the air in the filter core is difficult for draining, and causes the part filtrate not to be fully used, so this filter core needs exhaust structure preferably, also has, and this filter core filtrate hardens easily.Though and the up-flow filter core can be discharged the air in the filter core reliably, filtrate is difficult for hardening, and water outlet is short of power.So up-flow respectively has pluses and minuses with the filter core that falls two kinds of water flow modes of stream.
It is the advantage of attempting to make full use of two kinds of water flow modes that existing up-flow has the hybrid filter core that falls stream again, remedies two kinds of water flow modes shortcoming separately simultaneously mutually.A kind of existing up-flow has the hybrid filter core that falls stream again as China Patent No. 200420091003.2 " combined type filter core " has just disclosed, this combined type filter core comprises housing, housing bottom has opening, opening part is provided with an interior bucket that is connected with exhaust apparatus, be provided with the hollow-fiber module that fixes with housing in the interior bucket with the hollow fiber ultrafiltration membrane filtration, be provided with the delivery port that can supply the water behind media filtration to discharge in interior bucket bottom, and be provided with the silk screen that filtrate can be blocked in outside it at the corresponding site place of delivery port.During this patented technology filter core drainage, current pass earlier particulate filter from top to bottom and arrive the filter core bottom, flow out after rise to doughnut filter core top, passing hollow-fibre membrane then in top-down flow process again.Use two kinds of material for water treatment of active carbon and doughnut in this filter core, had multiple functions such as the look removed in the water, smelly, flavor, small organic molecule, larger molecular organics, bacterium and other granular suspension.But the exhaust structure of this filter core is complicated, and exhaust resistance is bigger, and filter process needs once more the air in the interior bucket upwards to be discharged, so influence the reliability of filter process startup when restarting filter process again after stopping the long period.
Summary of the invention
Technical problem to be solved in the utility model is at the prior art present situation, and a kind of combined type filter core is provided, and the mixed flow mode that this filter core adopts existing up-flow to have again and falls stream is filtered, and is applied on the special water purifier for drinking machine.Air in the filtrate thoroughly can be discharged during this filter element filtering, all filtrates all are fully used, and exhaust structure is simple and reliable, filtrate is difficult for hardening simultaneously, in addition, this filter core has multiple functions such as the look removed in the water, smelly, flavor, small organic molecule, larger molecular organics, bacterium and other granular suspension, and the drainage process starts reliable, stable effluent quality.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of combined type filter core, it comprises filtrate, up-hole plate, orifice plate, water inlet pipe and hollow-fiber module in housing, the housing, described shell nozzle which is provided with the interior bucket that can hold hollow-fiber module up; Be respectively equipped with the through hole that can allow interior bucket and water inlet pipe therefrom pass on described up-hole plate and the orifice plate; Described filtrate is located between up-hole plate and the orifice plate.
Described up-hole plate can be the part of the very little through hole in many apertures that distributing more densely thereon, also can be the parts that the part of the very big through hole in some apertures that distributing thereon and the silk screen that can stop filtrate combine, the periphery of this orifice plate is a ring-plane structure, lower surface at this ring flat-plate extends a short tube downwards, the outer surface of this short tube contacts with upper surface with shell nozzle place inner surface respectively with the lower surface of ring flat-plate, and adopts welding or adhesive method to make it fixedly connected; Described orifice plate can be the part of the very little through hole in many apertures that distributing more densely thereon, also can be the parts that the part of the very big through hole in some apertures that distributing thereon and the silk screen that can stop filtrate combine, this orifice plate is arranged on the position that certain distance is arranged at shrinking away from theshell body bottom, fixedlys connected with the housing madial wall in its neighboring; Described water inlet pipe internal diameter is not more than 10 millimeters, and its underpart is provided with delivery port, and its bottom contacts with housing bottom, and water inlet pipe and orifice plate also can be made one.
Bucket is to be extended up and down respectively and the pipe that forms is constituted by the material around the housing bottom central through hole in described, and the lateral wall of the pipe that extends to form downwards is provided with external screw thread.The top of bucket in the hermetically-sealed construction of described hollow-fiber module and interior bucket can be arranged on, the bottom of bucket in also can being arranged on, the hollow-fiber module lower end also is provided with fastening nut, and fastening nut is provided with apopore.
During this filter element filtering water, current flow to earlier the filter core bottom from top to bottom from water inlet pipe, pass orifice plate, filtrate and up-hole plate more from bottom to top successively and arrive filter core top, flow out after passing hollow-fibre membrane then in top-down flow process.Described water inlet pipe is less because of its internal diameter, and gas wherein is easy to be pressed onto the filter core bottom by current, passes up-hole plate again and enters filtrate.Current are easy to air is wherein upwards extruded filter core when passing filtrate, and the air in the filter core is thoroughly drained.It is reliable so the utility model filter core exhaust structure is simple.After the filter element filtering process stopped, the space in the filtrate still was full of water, and was a stable state, even still can restart filter process reliably at any time after filter process stops for a long time.
Described filtrate is a particulate filter, for example granular active carbon or KDF etc., and the filtering accuracy of the doughnut in the described hollow-fiber module is not more than 0.1 micron.Through active carbon and doughnut treated water, can remove in the water heterochromatic, foreign odor, peculiar smell, small organic molecule, larger molecular organics, bacterium and other granular suspension.
