It has a filter paper presser lid with numerous holes of 2m+ diameter. The lowest IC has a filter plate 22 that covers the majority of the 2m diameter.
Place the filter paper 21 between this filter plate 22 and the presser cover 2'00,
The number of filter papers is 1 to 5. In Fig. 4, 23 is a container that receives the nine water after filtration is completed in the receiver. These raw water receiver (Fig. 2A), first filtration part (Fig. 3B), second filtration part and receiver (Fig. 4C, D), H are stacked together as shown in Fig. 1. Use together. Note that 24 is a hooking part attached to the upper end of the sludge filtration part 1, which hooks the sludge filtration part 1 onto the raw water receiving tube 2. The lower end 26 of FIG. 3B is a lid holding cylinder, which holds down the holding lid 20 of FIG. 4C.
25 in Figure C of K4 is the knob of the presser cover 20.

When raw water in a state of action pollution is first put into the sludge filtration section 1 placed in the raw water receiver 2 of the raw water receiver A shown in Figure 2A, this sludge filtration section 1t's allows water to pass through, but sludge and Since it does not allow insoluble matter to pass through, coarse substances in raw water pollution-causing substances are removed. This sludge filtration section 1 has a hooking section at the upper end,
You can exchange it for this. The water, from which sludge and insoluble matters have been removed through the sludge filtration section, is coarsely filtered through a 60-mesh polyethylene cloth 4 and a filter plate 3 having a large number of 2-diameter holes at the bottom of the raw water receiver @2.

The water that has passed through the raw water receiver A'z follows a 40-mesh polyethylene cloth 9 and a filter plate 8 having a number of holes with a diameter of 2+m, and comes into close contact with the raw water receiver iA'fc first filtration section (Fig. 3B). The process moves to the first filtration section 7. The upper part of the first filtration section is an activated carbon chamber 12, which adsorbs and removes organic matter in the VCL water over a km, and allows it to flow down to the ion exchange resin chamber below.

As mentioned above, this activated carbon chamber has a claw 10 extending into the activated carbon layer below the filter plate 8, and two baffle plates are inserted into the activated carbon layer, so that the water flowing down is slowed down in the activated carbon layer. The contact area of the water-collecting material increases, and filtration efficiency can be improved. In addition, the bottom part has a slope of about 30 degrees.
Therefore, the water flows from the activated carbon chamber through the cross-shaped filter plate 13 and the 60 mm/7 mm polyethylene cloth tightly attached to it, and flows into the ion exchange resin chamber 15 below, which promotes water flow. By ion exchange resin.

Ammonia and heavy metals are removed. Already activated carbon chamber 12
Since organic matter is removed, the ion exchange resin will not be contaminated by organic matter.

Ionization (-) in water can be effectively removed.

Add anion exchange resin to cation exchange resin in an appropriate ratio
By mixing 5C, anionic substances can also be removed, so river water and rainwater can be filtered to obtain clean water. In this ion-exchange resin chamber, as in the activated carbon chamber, a polyethylene resin plate with small diameter holes 2i is suspended in the ion-exchange resin as a baffle plate, so water flows slowly and the filtration efficiency is improved. The water passes through the filter plate with two diameter holes at the bottom of the first filtration part and the 60 mesh polyethylene cloth below it, and then moves to the next second filtration part (Fig. 4C).

The bottom of the second filtering part (Fig. 4C) is 2+
A filter plate 22 having a large number of holes with a diameter of m, and a filter paper 2 on it.
One to five sheets of filter paper No. 1 are placed on top of the filter paper, and the filter paper is securely pressed with a holding lid 2010 having a large number of holes of two diameters and a lid holding cylinder 26 protruding from the bottom of the first filtration part. When pressed in this way, the filter papers will stick together, reducing water leakage and preventing air from entering between the filter papers. The presser lid 20 has a knob 25, so it can be easily attached and removed, and when the filter paper becomes dirty, it is easy to replace the filter paper, so that the filtration rate of the filter paper can be maintained effectively for a long period of time.

By increasing or decreasing the number of 1fc filter papers in the range of 1 to 5, the filtration speed can be changed depending on the quality of the raw water. The water thus filtered is finally put into the filtered water receiver 23 shown in FIG. 4C. This filtered water receiver has different shapes depending on the application.
You can change the size.

Effects of the Invention In the filter of the present invention, as a first stage, rough filtration is performed in the uppermost raw water receiver A to remove insoluble matters, and then the raw water is allowed to flow down to the first filtration section of the second stage.

This first filtration section B is divided into an activated carbon chamber and an ion exchange resin chamber below the activated carbon chamber, in which organic matter in the water is removed, and then ionized substances are removed by flowing down to the ion exchange resin chamber. Filtration can be carried out efficiently by filtering in stages in this order. The claws in the activated carbon chamber and the baffle plates placed in both chambers cause the water to flow slowly and the contact area with the filter material to be narrowed. You can feel the increasing effect. A combination of a filter plate 8 with a large number of holes of 2 diameters and a polyethylene cloth 9 of 40 meshes, and a cross plate filter plate 13 and 60.
The filtration rate can be stabilized by sequentially providing three combinations of mesh polyethylene cloth 14, a combination of a filter plate 17 having a majority of 2 m diameter on the barge, and a 60 mesh polyethylene cloth 18 from the top. can. The water that has been filtered through these sanitary passes is finally passed through filter paper in the second filtration section.
Depending on the quality of the raw water, the filtration speed can be changed by increasing or decreasing the filter paper between one and five sheets, and it can be quickly replaced if it becomes dirty. The filter of the present invention is used as a raw water receiver A when performing filtration.

The first filtration part, the second filtration part, and the receiver can be separated, so
Convenient for inspection and parts replacement. As described above, the filter of the present invention has remarkable effects compared to conventional filters.
