Description of the Related Art Recently, a hollow fiber membrane formed by bundling hollow fibers having innumerable fine pores has been used as a filter medium for filtering drinking water and the like. A hollow fiber membrane is a kind of filter that filters water by using fine pores in the wall surface of the hollow fiber.When used, water permeates the wall surface from the outside of the hollow fiber and flows into the inside of the hollow fiber. The dust in the water is filtered, and the water that has flowed into the hollow fiber flows out through the opening at the end of the hollow fiber. The hollow fiber membrane has an excellent performance of removing bacteria, but has not been widely used due to the following drawbacks. That is, when used for a long period of time, countless general bacteria adhere to the surface of the hollow fiber, which proliferates, and some chemical substances such as hydrogen sulfide generated therefrom are mixed in the filtered water, and the filtered water gives off a bad odor. It is a drawback.

In FIG. 6, 30 is a filter main body (hereinafter referred to as the main body), which has a water supply pipe 31 for guiding raw water in the lower part and a lid 33 having a discharge pipe 32 in the upper part. Reference numeral 34 is a hollow fiber that constitutes a hollow fiber membrane, whose wall surface is provided with innumerable fine holes, is bent into a U shape and is bundled, and its end portion 35
Is fixed to the hollow fiber membrane case 36 with a synthetic resin or the like. Reference numeral 37 denotes an activated carbon case, which has a raw water inlet 38 at the bottom thereof, which is filled with granular activated carbon 39 as a filter medium, and mesh filters 40 and 41 are provided on both sides of the activated carbon storage portion so as to prevent backflow and outflow of the granular activated carbon 39. I have it. Then, the hollow fiber membrane case 36 and the activated carbon case 37 are joined together to complete the filtration cartridge 42, which is inserted into the filter body 30. Reference numeral 43 denotes powdered activated carbon that adsorbs carcasses such as general bacteria attached to the surface of the hollow fiber 24 and hydrogen sulfide odor generated from the bacteria themselves.

That is, the raw water supplied from the water supply pipe 31 is subjected to removal of residual chlorine and the like by the granular activated carbon 39, and a turbid component such as iron rust and general bacteria are removed in the hollow fiber membrane configured by bundling the hollow fibers 34. Is discharged from the discharge pipe 32. The powdered activated carbon 43 adheres to the hollow fibers 34 so as to cover the surface by passing water. And this powdered activated carbon 43
However, it adsorbs the dead bodies of general bacteria attached to the surface of the hollow fibers 24 and the hydrogen sulfide odor generated by the growth of bacteria.

When the powdered activated carbon 43 is put into the hollow fiber membrane case 36, the powdered activated carbon 43 may be scattered in the air, and the powdery activated carbon 43 easily adheres to the surface of the hollow fiber membrane case 36, a work table, or the like. In addition, it may adversely affect electric equipment around the work place, and if the worker inhales powdered activated carbon floating in the air into the lungs, it may adversely affect the human body. Moreover, the powdered activated carbon 43 does not enter the inside of the hollow fibers 34 just by injecting it from above, but it is piled up on the bundle of the hollow fibers 34 as shown in FIG. 7 and becomes very easily scattered. . Therefore, it is necessary to handle it very carefully before fitting it with the hollow fiber membrane case,
The work efficiency had fallen.

In the figure, 1 is a cylindrical activated carbon case having a bottom and a granular activated carbon 2 is enclosed as a filter medium, and 3 and 4 are mesh filters for preventing the outflow of the granular activated carbon 2. The upper part of the activated carbon case 1 is subjected to an anchoring process for fitting with the hollow fiber membrane case, and a fixing base 6 for fixing the mesh filter 3 to a position slightly retracted from the anchoring part 5
Are formed. A space 7 having a height h is formed between the mesh filter 3 fixed on the fixed base 6 and the open end of the activated carbon case. For example, if the activated carbon case has a diameter of about 70 mm, h should be 10 mm to 20 mm. Reference numeral 8 is a raw water inlet provided at the bottom of the activated carbon case 1. Bottom net filter 4 is activated carbon case 1
Since a large resistance against the flow of water will be generated if it sticks to the bottom surface of the net, the mesh filter 4 is fixed from the bottom surface of the activated carbon case 1 with a space 9 in between.
活性炭ケース１へ封入される粒状活性炭２としては粒の
大きさが0.21〜0.24mmのものが用いられる。The granular activated carbon 2 to be enclosed in the activated carbon case 1 has a grain size of 0.21 to 0.24 mm.

置かれることとなる。Next, a manufacturing process until the filtration cartridge is completed will be described. First, the net filter 4 is attached to the bottom of the activated carbon case 1. Then, the granular activated carbon 2 is injected and the mesh filter 3 is attached. As shown in FIG. 2, the mesh filter 3 is placed below the open end of the activated carbon case 1 by h.

ートリッジが完成する。Next, the suction nozzle 12 of the vacuum suction device is connected to the inflow port 8 provided in the lower part of the activated carbon case 1 to start the suction operation. During the suction operation, the air flows in through the opening of the activated carbon case 1 as shown by the arrow A, passes through the space 7 and the activated carbon accommodating portion, and flows out toward the vacuum suction device. Then, in this state, the powdered activated carbon 13 is injected from above with a funnel or the like. The powdered activated carbon 13 is sucked into the activated carbon case 1 by the air flow as shown by the arrow B, and is sucked on the upper part of the mesh filter 3 as shown in FIG. By doing so, the powdered activated carbon 13 is prevented from diffusing into the air because the powdered activated carbon 13 is pressed and solidified on the upper surface of the mesh filter 3 not only during the operation but also after the completion of the operation. Then, when the activated carbon case 8 and the hollow fiber membrane case 7 are connected, a filtration cartridge is completed as shown in FIG.

細かさのものが用いられる。The filtration of this filter is performed in the same manner as in the conventional example by passing water along the arrow shown in FIG. The powdered activated carbon 13, which is pressed and solidified on the upper surface of the mesh filter 3 in the manufacturing process, enters the hollow fiber membrane case 36 by the water flow and adheres to the hollow fibers 34 as in the conventional case. As the powdered activated carbon, one having a fineness of 90% or more at 425 mesh is used.

Is an activated carbon case configured similarly to that of the previous embodiment,
Granular activated carbon 16 is enclosed inside, and powdered activated carbon 18 is injected above the mesh filter 11.

１μｍの粒子を除去可能である。A filter using a conventional filter cloth is used in a state in which powdered activated carbon is pre-coated on the outer surface of the filter cloth, that is, in a state in which a powdered activated carbon layer is formed on the surface of the filter cloth, and the powdered activated carbon layer is used in raw water. It is designed to remove dust. The powder activated carbon injection method that has been conventionally used for this type of filter is that powder activated carbon is first injected into the filter cloth case 19 as in the case of the hollow fiber membrane.
Needless to say, in this case as well, the problems described in the section of conventional problems occur. Therefore, when the cartridge of the filter using this filter cloth is constructed by replacing the hollow fiber membrane case and the filter cloth case in the previous embodiment as shown in FIG. Is eliminated and the assembly efficiency is greatly improved. The performance of the cartridge using the hollow fiber membrane and the filter cloth is as follows:
The hollow fiber membrane has a thickness of about 0.01 μm, and a filter cloth can remove particles of about 1 μm.

Therefore, the powdered activated carbon does not adhere to the outside of the case, the filter body, or the like during manufacture, and does not drift in the air, which makes it extremely easy to handle during manufacture and greatly improves work efficiency. .
