Fig. 1 is a structural representation of the present utility model.

Embodiment

Consult Fig. 1, a kind of ultrafiltration water-purifying machine, comprise and filter housing 1, be positioned at the intravital filter core of shell (4,5,6,7,8), water-in 2, water outlet 3, filter housing 1 and be connected in series and form by one-level cartridge filter 101, cascade filtration tube 102, three-stage filtration tube 103, level Four cartridge filter 104, Pyatyi cartridge filter 105 successively.

Polypropylene melt-blown fabric filter element 4 is set in the one-level cartridge filter 101, and filter before the sedimentation type in 5 microns in this filter core aperture, and silt, suspended substance, colloid, iron rust, solid impurity in can filtering water significantly reduce turbidity.

Granulated active carbon core 5 is set in the cascade filtration tube 102; extruded activated carbon filter core 6 is set in the three-stage filtration tube 103; ultra-filtration membrane filter core 7 is set in the level Four cartridge filter 104; ultra-filtration membrane filter core 8 is set in the Pyatyi cartridge filter 105, and the ultra-filtration

membrane filter core

7,8 of present embodiment adopts the polypropylene hollow fiber ultra-filtration membrane.Described level Four cartridge filter 104 is provided with back-purge system 9, comprises being arranged on the feed-water end recoil chamber 10 corresponding with the filter core position, is connected with sewage pipe 12 with the recoil chamber, and effluent outfall is provided with an opening-closing valve 11.The water entry of one-level cartridge filter 101, cascade filtration tube 102, three-stage filtration tube 103, level Four cartridge filter 104, Pyatyi cartridge filter 105 communicates with the clearance channel 13 that is arranged between filter core (4,5,6,7,8) and the cartridge filter (101,102,103,104,105).

When this equipment work, tap water advances water-in 2 and flows into one-level cartridge filter 101, to the clearance channel 13 between filter core and the cartridge filter, flow to the polypropylene melt-blown fabric filter element 4 that is provided with in the one-level cartridge filter 101 again, behind filter element filtering, flow out to the exit of one-level cartridge filter, but silt, suspended substance, colloid, iron rust, solid impurity in the polypropylene melt-blown fabric filter element 4 filtering water, water is filtered for the first time, make tap water significantly reduce turbidity like this; Flow to secondary filter cylinder 102 to one-level cartridge filter 101 water exit tap water, flow to clearance channel 13, clearance channel 13 through secondary filter cylinder 102 flows in the granulated active carbon filter core 5 of cascade filtration tube 102, heterochromatic, peculiar smell in granulated active carbon filter core 5 filterings (absorption) water, chlorine residue, hydrogenchloride, organism, part heavy metal, remove calcium carbonate, water is carried out secondary filtration; Tap water after the filtration flows into three-stage filtration tube 103 through the water exit of secondary filtration tube 102, the flow process of tap water is identical with cascade filtration tube 102 with one-level cartridge filter 101, three-stage filtration tube 103 built-in extruded activated carbon filter cores 6, extruded activated carbon absorption property and specific surface area are tens times of common gac, can the planar water of more strong profound level in objectionable impurities such as organic compound, chemical toxicant; Advance level Four cartridge filter 104 through three grades of effusive current of filter cylinder 103 water exits, level Four cartridge filter 104 built-in ultra-filtration membrane filter cores 7 are removed larger molecular organics, colloid, bacterium, algae etc. in the water, finish four filtrations.Feed-water end and corresponding position, filter core position are provided with recoil chamber 10 in the level Four cartridge filter 104, be connected with effluent outfall 12 with recoil chamber 10, effluent outfall is received sewage lagoon, the bacterium that ultra-filtration membrane is retained down. iron rust. colloid. suspended substance. when objectionable impuritiess such as larger molecular organics can be attached to the interior table of ultra-filtration membrane, easier obstruction of packing up ultra-filtration membrane is regularly washed the water production rate that the efficient recovery film can be arranged to ultra-filtration membrane.Open running water switch, simultaneously opening-closing valve 11 is opened, the dirt that is trapped is subjected to the pressure of tap water itself to be rinsed out ultrafiltration membrane filaments, becomes sewer, is discharged to sewage lagoon from draining sewage mouth.

For further improving the water quality of this water-purifying machine, the utility model also increases a Pyatyi filter cylinder 105 between fourth stage cartridge filter 104 and rising pipe 3, these filter cylinder 105 built-in ultra-filtration membrane filter cores 8, the impurity in the further filtered water of energy, various molecular level objectionable impuritiess such as colloid, pathogenic agent.The current process of tap water in Pyatyi filter cylinder 105 is identical with above-mentioned cartridge filter at different levels.At last, flow out from water outlet through the tap water after five filtrations, capable of direct drinking.

Used specific case herein the principle and the embodiment of the technical program are set forth, the explanation of above embodiment just is used to help to understand the method and the core concept thereof of the technical program; Simultaneously, for one of ordinary skill in the art, according to the thought of the technical program, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as the restriction to the technical program.
