Description

[Detailed Description of the Invention] [Industrial field of application] The present invention removes offensive odors and various dissolved substances generated in river water, pond water, well water, tap water, etc. and suspended substances such as rust to improve water quality. For water purification equipment for.

[Conventional technology]

It is known that filtration treatment is performed to purify water and various adsorption treatments are performed. As a simple device for carrying out such treatment, a water purification filter in which a container is filled with an adsorbent or a filter is used.

Such a conventional water purification filter is usually provided with a sheet-shaped filter material at the inlet and outlet of the container, and has a structure in which a powdery or granular adsorbent is filled between them, so that the water flow path is biased. There are problems that it is not easy to exert a sufficient water purification effect, that the filtration material is clogged with the adsorbent, the flow of water is restricted, and the water flow rate is not constant depending on the filling state of the adsorbent.

[Problems to be solved by the device]

The present invention has been made in order to eliminate the drawbacks of the conventional water purifying filter, and its purpose is to provide a water purifying filter that is small in size and has a large processing capacity, which can obtain a uniform water flow rate. .

[Means for Solving the Problems]

As described above, the object of the present invention is to disperse a powdery or granular adsorbent and a fibrous activated carbon between the layers of the multi-layer winding body formed from the fiber assembly sheet except for both ends. This can be achieved by holding the water filter.

As the fiber assembly sheet used in the water purification filter of the present invention, for example, a non-woven fabric made of synthetic fibers is preferable, but not limited thereto. As the adsorbent, known materials such as zeolite, ion exchange resin, and activated carbon can be used, but these may be in the form of powder or particles, or may be granulated.
These types are not particularly limited, and one type or two or more types can be used in combination.

[Action]

The water purification filter of the present invention can be used by inserting it in the middle of various water supply pipes or the like, or by filling it in a tubular or other container and attaching it to the outlet of a water faucet or the like.

If you purify water using the water purification filter of the present invention, you can efficiently purify a large amount of water because there is no outflow of adsorbent and clogging due to it, and a uniform and even water flow distribution is obtained. You can

〔Example〕

 An example of the water purification filter of the present invention will be described with reference to the drawings.

The water purification filter shown in FIG. 1 and FIG. 2 has a nonwoven fabric 1 formed by including heat-sealable polypropylene fibers rolled up from one end thereof to form a multi-layered columnar body, and both edge portions are provided between the respective layers. Except for 2 and 2, the granular adsorbent 3 and the fibrous activated carbon 4 are uniformly dispersed and sandwiched.

The water purifying filter thus configured is inserted into a cylindrical case 5 having a perforated bottom plate 5a as shown in FIG. 3, and its peripheral surface and the inner surface of the case 5 are adhered and fixed by an appropriate means, It was a unit type filter.

In the water filter having such a structure, when raw water is introduced from one end of the filter, the water flows evenly distributed along each layer, and comes into contact with the adsorbent 3 and the fibrous activated carbon 4. At the same time as the dissolved substances and the like are removed, the suspended substances are removed at the nonwoven fabric 1 part, so that purified water flows out from the other end of the water purification filter. On this occasion,
Both edge portions 2 and 2 exert the functions of removing suspended substances and preventing outflow of the adsorbent 3.

[Effect of device]

In the water filter of the present invention, since the adsorbent is securely held by the fiber aggregate sheet, it is possible to use the adsorbent having a fine particle size and a high adsorbing ability, and a compact and high-capacity water purifying filter is economical. In addition to the above, it has the feature that water purification filters with various capabilities can be manufactured arbitrarily.
