Description

[Detailed Description of the Invention] The present invention relates to an improvement in a water purifier that uses activated carbon precoated on a filter cloth.

The filter bodies used in conventional water purifiers of this type often have filter cloth bent into a bellows shape to increase the filtration area; The drawback is that the inner surface becomes clogged, reducing the filtration capacity and water collection efficiency.

The present invention was completed with the aim of providing a water purifier free of such defects, and the illustrated embodiments will be described in detail below.

Reference numeral 1 denotes a casing having a lid 2 and a handle 3, and a water supply pipe 4 extending toward the inner bottom of the casing 1 is vertically installed approximately at the center of the lid 2 of the casing 1. A water collection pipe 5 is provided in the horizontal direction, and a drain port 6 is provided on the lower surface of the water collection pipe 5. Reference numeral 7 denotes an appropriate number of annular filter bodies arranged concentrically within the casing 1 with different diameters, and the annular filter bodies 7 have a passageway 11 in their inner cavity.
A bag-shaped filter cloth 9 is covered with a holding ring 10 made of a synthetic resin net plate, which has a large number of pores on its inner and outer circumferential surfaces, and each annular filter 7 has a lower end thereof. The casing 1 is connected to the water collection pipe 5 through an appropriate number of communication ports 8 enlarged in the casing 1.
A required amount of powdered activated carbon 12 is housed inside.

The device configured in this way is stored in an outer container (not shown), and when raw water is supplied into the casing 1 from the water supply pipe 4, the raw water is stored in the casing 1.
A precoat layer is formed on the outer surface of the filter cloth 9 by stirring the powdered activated carbon 12 therein, and the water passage 11 is
It is the same as in conventional water purifiers to filter and purify the water sent into the casing by passing it through the precoat layer A and the filter cloth 9, but in the present invention, a water collecting pipe provided at the inner bottom of the casing 1 is used. Since the annular filter bodies 7 are arranged concentrically on the casing 5 with the required spacing between them, the total surface area of all the annular filter bodies 7 pre-coated with the activated carbon 12 is equal to the capacity of the casing 1. The raw water that passes through this wide-area precoat layer A passes through the filter cloth 9, where harmful substances and foreign odors contained therein are adsorbed and removed, and the water is purified. The water is sent to the water passage 11 through countless pores arranged on the circumference, collected into the water collection pipe 5 through an appropriate number of communication ports 8 provided at the lower end, and efficiently collected from the drain port 6. During this time, since the filter cloth 9 is wrapped around the ring body 10 and there is no bent part, there is little clogging, and the raw water filtration ability is extremely high.

As is clear from the explanation of the above embodiments, the present invention has an extremely high water collection efficiency with little clogging, and has the advantage of being able to supply water at low cost due to its simple structure, and has extremely high practical value. It is something.
