Abstract

The utility model discloses a device for supplying, filtering and purifying water, which is composed of a water inlet switch, a backwash switch, a water outlet switch, a water pipe, an outer shell, a faucet for turbid water, a base, a filtering core, etc. which form a whole. The utility model not only is provided with a water-purifying function, but also is accompanied with a backflow pollution discharge function, and the utility model plays an obvious role for ensuring the sanitation of water supply and improving water quality.

Description

The water supply filtration water clarifier

The utility model relates to a kind of tap water supply and crosses clarifying filter, especially with the water supply filtration water clarifier of sewage backwash function.

People's domestic water is just to be transported to the user from water factory through large, medium and small complex grid, unavoidably is subjected to the iron rust in the pipe network and the pollutions such as silt of deposition in the way.The water of often importing pipe network meets sanitary standard, increases with regard to turbidity to the user, and deteriorating water quality, this water supply is difficult to avoid.Current various small-sized filtration water clarifiers have very big effect to improving water quality, but they all do not have back purge system, and are slack-off when current occurring, when dirt blocks, have only and change filter core or took frequent cleaning apart, very inconvenient.

The purpose of this utility model is to be to provide a kind of can filter water purification, and the small-sized water supply filtration water clarifier of sewage backwash function is arranged again.

For achieving the above object, the utility model by switch, water pipe, shell, base, cross filter core and the fire hose is first-class forms.Be provided with the water purification filter core in the enclosure, and constitute the water inlet or the converting means of water outlet direction by switch and water pipe, be that to filter that water purification, current enter in crossing the filter core mouth when filtering in-core portion be exactly sewage backwash by the switch controls current from crossing when the filter core outside enters.

Adopted after above-mentioned such structure, owing to be provided with the water purification filter core in the enclosure, running water is further purified after filtering.Owing to the converting means of switch and water inlet of water pipe formation or water outlet direction, can make current enter the in-core portion of filtering again, flow out, carry out sewage backwash, the dirt of holding back is rinsed out through filtering layer by gauge tap from crossing the filter core mouth.

Below just further describe with the drawings and specific embodiments.

Fig. 1 and Fig. 2 are specific embodiment schematic diagrames of the present utility model.Situation when Fig. 1 filters water purification for the utility model.Situation when Fig. 2 is sewage backwash, (among Fig. 1 and Fig. 2, handle is parallel with water pipe for opening, and is vertical for closing) the utility model by water inlet pipe (1), water inlet switch (2) backwash switch (3), cushion rubber (4), base (5), shell (6), cross filter core (7), muddy water tap (8), clear water faucet (9), effluent switch (10) and outlet pipe (11) etc. and form.Shell (6) links to each other with the coarse silk line with base (5), and there is cushion rubber (4) sealing the centre, crosses filter core (7) and is connected on the base (5) with rib-loop, crosses the pore size filter 1-30 micron of filter core, and all the other each ones fuse with rib-loop.In the accompanying drawing 1, water enters through water inlet switch (2) and base (5) from water inlet pipe (1), obtain filtering through filter core (7), dirt was trapped within on the filter core (7), water after the filtration collected in base water pipe place, filter core (7) bottom, flow out through effluent switch (10) and outlet pipe (11), refute for the user and connect use, or open the water after clear water faucet (9) obtains filtering.(seeing accompanying drawing 1 direction of arrow) gathers at the dirt of crossing cartridge surface and to increase after filtering certain water yield, and resistance increases, and water speed slows down, and at this moment will carry out backwash.(see accompanying drawing 2) during backwash as long as effluent switch (10) is closed, muddy water tap (8) is opened, close water inlet switch (2), open and be close to road backwash switch (3), water enters the filtration in-core from being close to the road through filter core (7) oral area, passes element wall again and flows out.At this moment the dirt that accumulated in filter core (7) outside is left by the water flushing, collects in the shell (6), is discharged by muddy water tap (8).(seeing accompanying drawing 2 directions of arrow) to meet hydraulic pressure too low when backwash, do not have scouring abrasion power, recoils when invalid, can remove muddy water tap (8) down to shell (6) as the handle rotation, with manually cleaning.

The utility model can divide several specifications or model by the water yield and water quality requirement.

Claims
