The so-called stationary water purifiers, which are installed at home and workplaces for regular use, are specially designed for the odors of tap water, residual chlorine, dissolved harmful substances such as trihalomethane, iron rust,
In recent years, demand has rapidly increased in recent years as users have been welcomed by users who dislike the presence of foreign substances such as rubber dust, fine sand, and metal fragments.

[0003] However, stationary water purifiers are generally made compact and have a small volume, so that there is little time for potable water to come into contact with filter media and ore debris, and the water purification and mineral supply capacity can be sufficiently satisfied. It was not something.

[0004] As a method for solving this problem, a method of circulating water by arranging several capsule cartridges in parallel to repeat contact with a filter medium or an ore shard, making a capsule cartridge elongated and using a filter medium or an ore shard with the filter medium. Methods for extending the contact time have been considered. However, these methods are no longer compact devices and cannot be said to be suitable as stationary water purifiers.

Applicants have previously described a method for maintaining long contact times between drinking water and filter media or ore debris in a minimum number and relatively short standard length capsule cartridges. A patent application has been filed for an invention in which a water guide pipe having a spiral plate is provided so that drinking water passes along the spiral plate.

Further, on the upper or lower surface of the filter plate 4, a filter membrane 5 made of a nonwoven fabric of a material such as acetylcellulose, regenerated cellulose, polytetrafluoroethylene, polysulfone, polypropylene, or polyester is laid.

Similarly, a filter plate 6 is provided near the bottom 12 of the cartridge 1. The filter plate 6 is made in the same manner as the filter plate 4 and is fitted inside the cartridge 1 in such a manner as to cover the cartridge 1 densely. The filter plate 6 also has a filter membrane 5 made of a non-woven fabric like the filter plate 4.
Is laid. The filtering material 8 or the ore crushed pieces 8 used for purifying the source water or the like is filled between the filter plate 4 and the filter plate 6.

Between the filter plate 4 and the filter plate 6 inside the cartridge 1, a suitable number of baffle plates 7 having a diameter smaller than the diameter of the cartridge are accommodated so as to be alternately overlapped with the filter material 8 or the ore fragments 8. ing. That is, the baffle plate 7 is formed to have a length and a width shorter than the inner diameter of the cartridge 1, and is horizontally or upwardly or downwardly inclined at an appropriate angle to be sandwiched between the filter medium 8 or the ore fragments 8. It is. The baffle plate 7 is not fixed to anything inside the cartridge 1 but is merely sandwiched between the filter material 8 or the ore crushed pieces 8.

The number of the baffle plates 7 to be used is arbitrary, and may be one or a plurality of baffle plates, which may be determined in consideration of the vertical length of the cartridge 1. Is for the purpose of extending the residence time in the drinking water cartridge 1. Therefore, the longer the number of baffles 7, the longer the residence time of the drinking water.
Or, since the volume of the ore fragments 8 is reduced, the number is about 2
The range is from 10 to 10 sheets, preferably about 2 to 6 sheets.

In the present invention, the shape of the baffle plate 7 to be used may also be arbitrarily made, and may be rectangular, semi-circular, semi-elliptical, trapezoidal, triangular, or any other shape. A flat plate shape having a considerable area is preferable. Preferably, the baffle 7 is made as thin as possible to reduce its volume.

In a preferred embodiment of the present invention, the baffle plate 7 is slightly longer than the radius of the cartridge 1 and its width is set to about 1/4 to 1/8 of the circumferential diameter of the cartridge 1.
Six or more pieces are made, and they are alternately opposed to each other at regular intervals in the vertical direction so as to be supported by the filter medium 8 or the ore fragments 8. In this way, assuming that the filter material 8 or the ore crushed pieces 8 are not present, when the lid 11 is removed and the cartridge 1 is viewed from directly above, the plurality of baffle plates 4, 4. The bottom portion 12, to be precise, a filtration membrane 5 or a filtration plate 6, which will be described later, is completely or almost invisible (see FIGS. 1 and 3).

Alternatively, in the method of the present invention, the baffle plate 7 has the same shape as the filter plates 4 and 6, that is, a large number of small-diameter or a small number of relatively large-diameter holes 71.71.71. It may be made into a thing made to be made, and this may be made to be clamped by filter medium 8 or ore fragment 8 (refer to Drawing 2). The water flowing in the cartridge 1 is blocked by the baffle plate 7 and temporarily stagnates, and passes through the holes 71 having a small area.

The filter material 8 or the ore crushed pieces 8 is used for purifying drinking water or dissolving minerals therein. The filter material 8 used in the present invention is preferably in the form of powder, granules or powder and granules that can be filled without gaps between the baffle plates 7.

As a further alternative, according to the method of the present invention, the water purifier used for this is communicated with the water injection pipe 2 to hang down the inside of the cartridge 1 and open the filter plate 6 and the filter membrane 5 attached thereto. An inner hollow water pipe 9 that fits into and communicates with the through hole may be attached, and an appropriate number of the baffle plates 7 may be placed between the water pipe 9 and the side portion 13 of the cartridge 1 [FIGS. 5 (B) and FIG. 6 (B)]. That is, the baffle plate 7 is inclined at a right angle or a vertical direction with respect to the water pipe 9 so as to be sandwiched by the filter medium 8 or the ore crushed pieces 8, and the tip thereof is preferably in close contact with the inner wall of the cartridge 1. I have to. Therefore, in this case, the baffle plate 7 covers the space between the water pipe 9 and the cartridge 1, that is, over the length of about the radius of the cartridge 1. When a plurality of the baffle plates 7 are attached, they are attached at regular intervals in the vertical direction and at different angles in the horizontal direction, and it is assumed that there is no filter material 8 or ore fragments 8, and then these are lowered. It is preferable that the number of visible portions of the filter plate 6 or the filter membrane 5 when viewed is as small as possible (see FIG. 3).

Still further, according to the method of the present invention, the water purifier used in the method is constructed such that the side portion 13 of the cartridge 1 is doubled, and the purified water is stored between the two side portions. This can be done [see FIG. 6]. That is, an inner portion 131 having a shorter vertical dimension and a smaller diameter than the side portion 13 is planted on the bottom portion 12 so as to be in contact with the side portion 13 with a gap inside the side portion 13 of the cartridge 1, or A bottom lid 122 having a water injection hole 123 communicating with the water inlet 121 is attached to the portion 131, and the bottom lid 122 is placed or fixed to the bottom 12 so as not to leak water. The inner portion 131 is filled with the filter material 8 or the ore crushed pieces 8 so as to sandwich the baffle plate 7. And this inside part 1
The filter plate 4 is attached to the base 31 so as to cover it tightly, and the filter medium 8 or the ore fragments 8 are placed below the inner part 131 in such a manner that the inner part 131 is tightly covered with the inner cover. The filter plate 6 is fitted inside. As described above, a filtration membrane 5 made of a nonwoven fabric is laid on the upper or lower surfaces of these filter plates 4 and 6 as described above.

The water purifier used in the method of the present invention is configured as described above, and is used as follows.
First, the water supply pipe 2 of the cartridge 1 is connected to a water source such as a water tap or a hose connected to the tap. Drinking water from a water source is guided to the water supply pipe 2 and rises through the water supply port 121 of the cartridge 1. The rising drinking water passes through the holes of the filter plate 6 and the filter membrane 5 and passes through the filter 8 or the ore fragments 8.
Rises along the baffle plate 7 in the space filled with. Therefore,
The rising of the drinking water in the cartridge 1 becomes slower in accordance with the number of the baffles 7, the contact time with the filtering material 8 or the ore fragments 8 becomes longer, and the purification by the filtering material 8 of the drinking water or the mineral by the ore fragments 8. The dissolution of the minute is more fully achieved. In this manner, the drinking water that has risen in the filter medium 8 or the ore crushed pieces 8 in the cartridge 1 is supplied to the holes 41, 41, 4 of the filter plate 4.
1 and the filtration membrane 5, and is drained from the drain port 111 of the lid 11 of the cartridge 1 through the drain pipe 3,
Served for beverages.

As an alternative, holes 71 and 7 are formed in baffle plate 7.
In the case of using one in which 1, 71... Are scattered, the drinking water is regulated by the baffle plate 7 while these holes 71, 71, 71.
Is as described above.

Further, as an alternative, when the side portion 13 of the cartridge 1 is doubled, the drinking water that has risen and passed through the filter plate 4 and the filtration membrane 5 is stored between the side portion 13 and the inner portion 131. Then, the water is drained from the drain port 111 of the lid 11 of the cartridge 1 through the drain pipe 3 and provided for a beverage.

As a further alternative, in the case where a water pipe 9 with a baffle plate 7 is provided inside the cartridge 1, drinking water from the water source descends from the water injection pipe 2 through the water pipe 9 and the filtration membrane 5 And through the through hole of the filter plate 6 to reach the bottom 12 of the cartridge 1, and thereafter sequentially pass through the hole of the filter plate 6 and the filter membrane 5 by water pressure to obstruct the inside of the filter medium 8 or the ore debris 8 being filled. It rises along the plate 7 and the lid 1
The water is drained from the first drain port 111 through the drain pipe 3 and provided for a beverage.

In the water purifier used in the method of the present invention, drinking water to be treated is injected from the drain pipe 3 in the reverse of the above-described method, and the inside of the cartridge is lowered along the obstacle of the baffle plate 7. It is recognized that the water can be discharged from the water inlet 121 and used for drinking.

[0026]

According to the water purification method of the present invention, the drinking water to be treated flows along the baffle plate disposed inside the cartridge, so that the residence time of the drinking water in the cartridge can be prolonged. Since the contact time with the filter medium or the ore shards filled in the cartridge is prolonged, there is an advantage that purification of drinking water and dissolution of mineral components can be sufficiently performed. In addition, the method for purifying and purifying water of the present invention is a highly versatile method using a device having a simple structure in which a baffle plate is sandwiched between filter media 8 or crushed ore pieces 8 filled in a cartridge.
