Description of the invention: [Technical field to which the invention belongs] The present invention relates to a water purification filter, which can remove turbidity, residual chlorine, trihalomethane, and soluble insoluble water contained in tap water. dissoluble lead) and so on. [Previous technology] Generally, river water and groundwater are used as the source of tap water. However, in order to supply safe tap water in the garden and various industries, raw water is added to various water purification plants in various water purification plants to purify the water. deal with. In recent years, the quality of water sources such as river water and groundwater has deteriorated, and each water purification plant has been depleted. The quality of tap water that is free of supply has deteriorated, and more chlorine has to be added than in the past. Therefore, especially in urban areas, tap water has a serious problem such as foulsty or chlorine odor. ^ In order to remove the odor of tap water, households and various industries have widely used water purification devices. This type of water purification device generally uses activated carbon and hollow fiber membrane (hQiiQwfbermembraj ^). It can remove moldy smell and odor, and hollow fiber membrane can remove turbid particles. In addition, Hlin membrane also has the function of removing the bacteria at the active carbon site. In recent years, not only the problem of odor or turbidity of tap water, but also other problems such as trace amounts of trihalogens, solubility, and other problems, so the water device has the effect of removing more f. Although silk carbon has the effect of dihalomethane in 1 square meter, it has almost no effect on removing soluble lead. 4 To remove soluble errors, ceramics such as ion exchange resin (ion ⑽angereSm) or zeolite must be tested. 200524830 For example, Japanese Invention Patent Publication No. 2001_353486 proposes a method that can improve the use efficiency of activated carbon, ion exchange resin, and ceramic materials (filter fementor filtermedi painting), and effectively utilize the internal water purification filter to reduce the volume. Water purification filter. The composition of this conventional water purification filter? Is shown in FIG. As shown in FIG. 3, the water purification filter r is composed of a filter material storage portion 2 and a hollow fiber membrane storage portion 3. As indicated by the arrow in the figure, water flows from the filter medium storage portion 2 to the hollow fiber membrane storage portion 3. The filter material storage valley 6 having an opening 5 through which water can flow in from the outer wall is stored in the filter material storage portion 2. In addition, the intermediate fiber membrane 4 is housed in the hollow fiber membrane storage unit 3. A filter material storage container inner tube 9 is installed at the center of the filter material storage container 6 and has a water inlet 7 at the periphery and a water outlet § at the downstream of the water flow. Filter tube 10 is filled between the tubes 9. Water flows in from the tap water supply unit 11 provided at one end (lower in the figure) of the filter medium storage unit 2 and flows into the inside through the outer wall opening 5 of the outer tube 6 of the filter medium storage container, passes through the filter medium 10, and then from the inner tube 9 of the filter medium storage container. The peripheral part inlet 7 flows into the inside of the filter medium storage container inner tube 9, and finally flows out from the water outlet 8 of the filter material storage container inner tube 9 in the direction shown by the arrow A and flows to the hollow fiber membrane 4. —. At this time, according to the composition of the conventional water purification filter 1 described above, the water flowing out of the water outlet 8 of the inner cylinder 9 of the filter material storage valley will locally flow into the central portion of the hollow fiber membrane 4, resulting in the inability to effectively use the hollow fiber. The membrane 4 has an entire filtering surface. In addition, if the inner diameter of the inner tube 9 of the filter material storage container is small, the flow rate of water flowing out of the water outlet 8 of the inner tube 9 of the filter material storage container will be accelerated, and damage will occur to the central portion of the hollow fiber membrane 4 where the water directly flows into. There is also the possibility that the life of the hollow fiber membrane 4 is reduced. [Abstract] 200524830 The present invention can provide a solution for the above-mentioned conventional technology, that is, to provide a water purification filter that can give full play to the filtering function of hollow fiber membranes while improving quality and extending the life of hollow fiber membranes. The water purification filter of the present invention is a filter material kiss portion that stores the filter material, and the core = out 4 is a hollow fiber membrane storage portion that can store a hollow fiber membrane.

Therefore, it is possible to make full use of the water quality of acetonitrile of hollow fiber membranes. In addition, even when the speed of 1 muscle flowing out from the inner container of the filter material storage container increases rapidly, there is no need to worry about damaging the hollow fiber membrane due to the water diffusion effect of the separator, and the life of the hollow fiber membrane can be extended.

This sealing material 27 prevents the water supplied from The filter material is stored in a state of overflow from the periphery of 6 to the hollow fiber membrane 4 and overflows. # 图 2 所 'The peripheral wall of the dome-shaped partition is provided with, for example, 4 = 孔 28 ’. And as shown in FIG.}, A flange portion having a diameter larger than that of the partition plate η and a top portion of the peripheral portion of the water outlet 8 of the filter medium storage container 9 is formed below the periphery of the dome-shaped partition plate 13 as shown in FIG. 28. Below the flange portion 28, a cylindrical portion 29 inserted into the filter material storage container 9 along the water flow outlet 8 of the inner tube 9 is integrally formed. In this embodiment, as shown in the figure, the height of the partition plate 13 and the height of the upright portion 15a of the peripheral portion of the gland 15 are slightly the same. This allows the partition 13 to be included in the height H range of the gland 15. In addition, the periphery of the partition 13 opposite to the hollow fiber membrane 4 of the gland 15 is provided with a marginal reduction from the beginning of the partition 13 (For example, six) forward flow ribs 14 for radiating the diffused water from the partition plate 13 in a radial direction. In addition, a non-woven fabric 17 is arranged on the upstream side of the hollow fiber membrane 4 and passes through the entire water course. In FIG. 1, a dotted arrow indicates a water flow. The water flowing in from the tap water supply part η flows into the outer part of the filter material storage volume 10 200524830 from the outer wall of the filter material storage container outer tube 6; 1 material 1Q, and then flows from the inner tube 9 of the filter material storage container 9 in a straight direction to the wrong water outlet 8 Opposing the opposite side | The plate 13 of the inner cylinder 9 of the material storage container is impacted, and the water vapor ^, the water flowing out of the water outlet 8 and the peripheral wall of the partition plate 13 are horizontally oriented. Next, from the material formed on the rSW day, * L · soil h hole 28 toward the hollow fiber of Ligai, it was put into a pseudo-puppet. After the water flowing out of the yoke hole 28 'is formed into a radial shape by the rectifying ribs 14, it is diffused through almost all areas on the front side. The pair of ^ η ϋ 5 of the middle worker_version 4 is now fed with the water spread by the 敕 &, g, a partition 13 and passed through the non-woven fabric 17, the claw octadecylone, and the pancreas 4. The white powder and fine powder combined in the water can be made of non-woven fabric. 17 ^ = The utilization efficiency of the membrane 4 is improved, and the early blocking of the middle fiber can be prevented by the water outlet δ of the inner tube 9 of the filter material storage volume 11. The partition plate 13 ′ is placed so that the water flowing out from the water outlet 8 is affected by the partition plate 5 and the dry second-rate towel _4. With this result, the finished surface can be uniformly and effectively used to improve the performance of Wangfan Qiqi Ningong Fibronamine 4, which can improve the water quality. Especially 9 5-The flow velocity of the water from the inner 9 will be slower, and the damage will be avoided. The inner tube 9 of the filter material storage volume 11 is thinner, which can expand the order product of the filter material 10. As a result, the hollow fiber membrane 4 can be extended. life. In addition, an integral partition plate 13 is formed to effectively utilize the pressing cover 15 of the filter medium 10, thereby preventing an increase in the number of parts. In addition, for the configuration of the container 15 and the cover 15, the partition 15 is within the range of the size Η, which can prevent the sanitation of the water purification filter 丨. In addition, the flange 28 of the partition plate 13 and the upper end of the peripheral portion of the water outflow port 8 of the inner tube 9 of the filter medium storage container are in a state that the tube portion 11 of the partition plate 13 200524830 29 is along the water outflow port 8 of the inner tube 9 of the filter medium storage container. The position of the partition 13 of the fine peach 纟 _ _ pair can be easily determined, and the convenience of assembly operation is improved. In addition, in order to form the ribs 14 by pressing the base material 10 with the gland 15, when the number of parts is prevented and the water purification is prevented, the rectifying ribs 14 also have the effect of rectifying the incoming water to the membrane. As a result, the utilization efficiency of the hollow fiber membrane 4 can be improved. In addition, the upper end 绫 P of the lower case 19 of the filter material storage portion 2 is protruded in a ladder shape. In the upper case 31 of the drop portion 3G, the lower < inner diameter dimension D and the inner diameter dimension E of the upper case 31 are approximately the same. As compared with the conventional example in FIG. 3, the filter material can be enlarged. Content product.合 如 外 冋 6 ^ Also, in the conventional example of FIG. 3, the hollow fiber membrane storage unit 3 system is fitted with screws or the like to the outer shell of the lower housing of the filter medium storage unit 2, = The inner diameter D is smaller than the inner diameter E of the ㈣1. On the contrary, as shown in the present embodiment, because the difference 30 of the upper casing 31 of the hollow fiber membrane storage section 3 varies, the outer diameter of the outer tube 6 of the sacrificial material storage container can be enlarged and the filter material storage can be enlarged. The inner volume of the container outer tube 6. In addition, the thickness of the upper case 31 of the hollow fiber membrane accommodating part 3 and the _ 19 of the button part 2 is approximately constant, and it is accessed by ultrasonic fusion vibration: it can ensure the strength of the case and can have a high enough joint force. The mouth can be so. According to the water purification filter 1 of this embodiment, even if the size of the conventional filter is slightly the same, the volume of the filter medium 10 can be enlarged by expanding the space outside the filter material storage container / 7 nanometers, and Increase the utilization efficiency of hollow rafters to prevent early blockages. Using this effect, even if the volume of the filter material 10, 12 200524830 hollow fiber membrane 4 becomes slightly smaller, it can maintain the water purification function equivalent to or more than that of a conventional water purification filter, and can have a longer life. Therefore, the water purification filter 1 can be made smaller than the conventional water purification filter. In the foregoing embodiment, a dome-shaped partition 13 is formed at the center of the pressure cap 15 of the outer cylinder 6 of the filter material storage container. However, the dome-shaped partition 13 is not limited to this configuration, and a dome-shaped partition 13 may be separately formed. , And then fit into the hole formed in the center of the gland 15. In addition, the partition 13 is not necessarily dome-shaped, and may be other shapes.
