Abstract

The utility model relates to a water purification device can be used in a drinking water feed system or an individual filter, in particular to a domestic water filter. The quality of the purified water is improved by spirally arranging large filtration particles and increasing the amount of water purification channels. The domestic filter comprises a housing with separation grids arranged at the water inlet and the water outlet thereof, and two or more spiral baffles. The baffles are provided with flat belts or rod-shaped pieces winding along the longitudinal axis, as well as three or more beam pieces, and one or more flat baffles separating the water inlet and the water outlet can be additionally arranged.

Description

The service water filter

Technical field

This utility model relates to water purification installation, and can be used in drinking water supply system and the independent filter.

Background technology

SU1517976A1 is maximally related prior art, it discloses a kind of filter that is used for decontaminating liquid, it comprises the shell with one or several helical baffle plates of realizing with step continuously or alternately, and particulate filter arrangement is positioned at the distribution barrier of filter delivery port.

The defective of existing technical scheme is that the drink water purifying quality is low.

Summary of the invention

In the utility model, the technical result of the scheme that is proposed is, by along filtering the length that increases the water purifying paths with two of the bulky grain filter of helix shape or more paths, obtains the high drinking water that purifies quality.

Household filter comprises the shell with helical baffle plates, dividing plate has the blade of being made by a flat band of two axis coilings longitudinally, perhaps have three and more blades of realizing with step continuously or alternately of making by three or more beam type spares, filter filtrate with the bulky grain of arranging with helical form, and the distribution barrier that is positioned at water inlet and delivery port place, the edge of helical baffle plates closely contacts the side surface of shell along whole length.

Household filter with two helical-like path of moving in succession provides an additional dividing plate to separate intake-outlet.

In household filter with three helical-like path of moving in succession, a blade also adds at two ends flat barrier is provided, each end of this blade all has flat barrier on two other blade adjacent with this blade, and intake-outlet is located between the adjacent flat barrier.

The specific embodiment

Fig. 1 has shown a kind of family expenses water filter, and it has the cylinder blanket 10 of band upper end wall and lower end wall, and described upper end wall has water inlet 6 and lower end wall has delivery port 7.Selectively, described water inlet and delivery port can be located at described shell 10 on the side of endwall region.In Fig. 1, with reference number 6 ' mark import, with the outlet of reference number 7 ' mark.In described cylinder blanket 10, in a certain distance of the described end wall of distance, be provided with and

distribute barrier

4 and 5, be provided with helical baffle plates 20 between

barrier

4 and 5, the axis that the axis of the rotation of this helical baffle plates and described cylinder blanket 10 and described particle filter filtrate 13 coincides.Described

distribution barrier

4 and 5 can filter filtrate 13 with described particle and described helical baffle plates 20 is fixed between

barrier

4 and 5 thereby be provided with.

Filter shown in Figure 2 and the difference of filter shown in Figure 1 are that described delivery port 7 is arranged in the top of shell 10 end faces identical with water inlet 6.The dividing plate 8 of the water-stop of rectangle is set between entery and

delivery port

6,7, and the lower edge of this dividing plate runs through distribution barrier 4 and docks with the upper limb of described helical baffle plates 12.The lateral margin of this dividing plate 8 is arranged to respectively closely contact with the upper surface with the sidewall of described shell 10 with upper limb.In the filter of this structure, two passes moves in succession, thereby the path that water is flowed through increases, and this has improved the quality of purifying waste water.

This household filter running following (Fig. 1 and 2):

Water to be filtered supplies on the described distribution barrier 4 by water inlet 6, and water filters filtrate 13 along bulky grain and flows along helix, is purified and by described

distribution barrier

5 and 7 outflows of described delivery port.

Because the thickness of described dividing plate is compared and can be ignored with the cross section of described shell, so when current are assigned with in two or more the parallel channels, whole current change hardly, thereby the size that need not change described shell just can realize improving the target that purifies water.

The increase of number of channels (that is to say between the spiral blade, the increase of " import volume " of described helical duct) makes that the current in each passage are consistent more, generally speaking this just means because in fact their parallel running makes and improved filtering water under the situation that does not reduce filtering velocity.

Fig. 3 to 5 has shown a kind of filter that comprises three helical baffle plates.Fig. 3 has shown three helical baffle plates that formed by trilete rays strip type spare.Fig. 4 to 5 shown filter axially on the schematic diagram of cylindrical a kind of filter, 1 and 1 ' top and bottom that indicate first blade wherein, 2 and 2 ' indicates the top and bottom of second blade, 3 and 3 ' indicates three-vaned top and bottom.

Therefore, first blade comprises flat barrier 1 and 1 ' at two ends, and its each comfortable side joins with corresponding flat barrier 2 and 2 ' and 3 and 3 ' on two other blade respectively, and water inlet and delivery port are arranged on the both sides of dividing plate 1 and 1 '.The water inlet of Figure 4 and 5 is arranged between upper baffle plate 1 and 2, and delivery port is arranged between the lower partition 1 '-3 '.Upper baffle plate 1 closely contacts with the upper end wall of described shell 10 with 2, and upper baffle plate 3 does not closely contact with the shell upper end wall.Lower partition 1 ' closely contacts with the lower end wall of described shell 10 with 3 ', and lower partition 2 ' does not closely contact with the shell lower end wall, but leaves the gap apart from lower end wall.

Can be used as the extension of described helical baffle plates self and form described dividing plate.

The step of helical baffle plates rule of thumb is chosen as constant or alternately changes, and this depends on predetermined degree of purification and predetermined filtering velocity.

According to the requirement of water depuration quality, described bulky grain filters filtrate and is selected from as sorbing materials such as active carbon, synthetic zeolite, schungites; Ion-exchange filtrate (ion exchange resin), porous filter-material (polypropylene), haptoreaction filtrate (KDF) and be combined with the mixing filtrate of the performance of different component filtrate.

Filter filtrate in the household filter and be divided into a plurality of passages, described a plurality of passage can walk abreast or operation in succession, the bulky grain that wherein can be filled with the different component that prevents to form raceway groove in the passage of same filter filters filtrate, does not obtain high-quality drinking water thereby can not change actually under the situation of filter size.

When contrast has (Fig. 6) helical baffle plates and do not have in the filter of (Fig. 7) helical baffle plates, when identical bulky grain filtered state behind the water gaging such as filtrate purification, this was just obvious.

In Fig. 6, filtering filtrate is uniformity, and can see washout district and raceway groove in Fig. 7.
