Mode for the Invention
[26] Hereinafter, the preferred embodiment of the present invention will be described in detail with reference to the appended drawings.
[27] In the present invention, FIG. 2 is a front cross-sectional view of a ceramic filter with a round type segment filtering element according to one embodiment of the present invention, FIG. 3 is a cross-sectional view of an upper round constituting the round type segment filtering element according to one embodiment of the present invention, FIG. 4 is a bottom view of the upper round shown in FIG. 3, FIG. 5 is a cross-sectional view showing the upper round and a lower round constricted to be symmetric with the upper round by separating them at a state prior to the assembly, FIG. 6 is a cross- sectional view of the ceramic segment filtering element according to one embodiment of the present invention, and FIG. 7 is a cross-sectional view showing formation of a carbon layer on surface of the ceramic segment filtering element shown in FIG. 6.
[28] Referring to FIG. 2, a plurality of segmented filtering elements, for instance, two to one hundred numbers, is stacked in the cartridges 1, 3 thereby maximizing the infiltration area of a filtering element 21 by raw water into an inlet opening 7 of the cartridge 1.
[29] Referring to FIG. 3 to FIG. 6, the round type segment filtering element 21 is characterized by being shaped as a round formed with a through hole at center, and formed with a hollow opening 23 at the inside in a donut shape communicating with the through hole 27 by means of an infiltration opening 25.
[30] Referring again to FIG. 3 to FIG. 6, the round type segmented filtering element 21 with the above stricture, is manufactured by charging 50 to 90 wt.% of elvan powder, 5 to 25 wt.% of clay powder, 5 to 25 wt.% of yellow soil powder, into a ball mill, finely pulverizing them into particles below 1/im for about 12 to 16 hours, adding a binder including polyvinyl alcohol (PVA) to the resultant fine powder by 1 to 3 wt.% with respect to entire fine powder thereby forming them into granules, molding an upper round plate 21a and a lower round plate 21b by means of a high molding press as intermediate shapes, and pining the upper round plate 21a and the lower round plate 21b to each other by means of a ceramic adhesive thereby forming the round type ceramic filtering element formation body.
[31] In this regard, as shown in FIG. 5, the upper round plate 21a and the lower round plate 21b are formed to have a symmetric structure. Also, as shown in FIG. 3 to FIG. 5, the upper round plate 21a and the lower round plate 21b are formed with outer projections 29a, 29b for defining outer walls of the hollow opening 23 and inner projections 31a, 31b for defining an inner wall 31 of the hollow opening 23 at an outer peripheral surface of a pining surface, and a recess between the outer projections 29a, 29b and the inner projections 31a, 31b. Furthermore, a portion of the inner projections 31a, 31b is opened to thereby provide openings 25a, 25b for defining the infiltration opening 25. After drying the round type ceramic filtering element molding body by pining the upper and lower round plates 21a, 21b having a such structure, it is sintered at proper temperature sudi as 900? to 1200? at an earthenware state thereby forming a space for particulates having a size of 0.1 to 0.3/im, resulting in the formation of porous stricture.
[32] The present invention uses elvan and yellow soils, which are profitable to human body, as materials for ceramic, so that germanium component contained in the elvan and mineral component contained in the yellow soil, and the like, which are profitable to human body, can be dissolved into water.
[33] As shown in FIG. 7, it is possible to provide sterilization and deodorization functions to the filtering element and to add sweet fragrance to the purified water by forming a carbon layer 32 on the surface of the round type segmented filtering element, through suctioning by dissolving one selected from a mono-saixharide, a disatcharide, and a polysaccharide, including a glutinous starch syrup, sugars, and a grape sugar, and the like, drying it, and then heating it without oxygen at about 400? temperature.
[34] As shown in FIG. 2, when the round type segmented filtering elements 21 are stacked into multi-layers by means of an assembly plate 37, a stacking tube 15, a closing cap 19, and an air-tight ring 33, water supplied through an inlet opening 7 of the cartridge is at first filtered at the plurality of round type segmented filtering element 21, and passes through the hollow opening 23 formed in the filtering element, the infiltration opening 25, a guide groove 17 of the stacking tube 15, and a guide opening 18 of the stacking tube 15 sequentially, and then it is discharged through a water outlet opening 9.
[35] In this regard, the round type segmented filtering element 21 is stacked in the stacking tube 15 with interposing the air-tight rings 33, and the stacking tube 15 is formed with the guide groove 17 and the guide opening 18 as water passageways for guiding the purified water from the infiltration opening 25 of the round type segmented filtering element 21 to the outlet opening.
[36] The stacking tube 15 is molded by mixing 1 to 99 % by mass of activated carbon particles, 1 to 99 % by mass of zinc alloy particles, and 1 to 99 % by mass of aluminum alloy particles, thereby adding sterilization action and sweet fragrance to the water passing through the guide groove 17 of the stacking tube 15.
[37] The assembly plate 37 functions to support the stacking tube 15, and the segmented filtering element 21 in addition to partition between the water inlet side and the water outlet side, however, it is not required when a lower end of the stacking tube 15 is directly connected to a lower end of the water outlet opening 9.
[38] Referring to FIG. 8 to FIG. 10, the segmented filtering element can be formed into a slender tube with one end thereof opened and the other end thereof closed. A plurality of slender tube type segmented filtering elements 35 is inserted and disposed into the assembly plate 35 in the longitudinal direction, and it is mounted in the cartridges 1, 3. In this instance, the assembly plate 35 performs to support the segmented filtering element 35 in addition to partition the water inlet side and the water outlet side. The raw water flowed into the water inlet opening 7 of the cartridges 1 , 3 infiltrates into the slender type segmented filtering element 35, and then it is flowed into the hollow opening 39 and is discharged through the water outlet opening 9 connected to the hollow opening. As shown in FIG. 10, the slender type segmented filtering element can be also formed with the carbon layer 32, as was in the round type segmented filtering element.
[39] Referring to FIG. 11, as shown in FIG. 12, a portable or desktop-type water purifying device can be constricted by disposing the ceramic filter 102, 104 of the present invention as a primary filter, and an adsorption filter 106 containing the activated carbon 41, light-fragrant grass 43, tree particles 45, rock bed particles for complementing mineral, and the like, as a secondary filter. In this instance, the adsorption filter 106 functions to sterilize, taste the sweetening, complement a nutrient svch as mineral, and the like.
[40] Thus, since the ceramic filter of the present invention is constricted that the filtering elements are consisted of a plurality of stacked round type filtering elements or a bundle of slender tube type filtering elements, the infiltration surface area can be maximized with respect to the conventional single cartridge with single filtering element, so that the purifying capacity can be increased by several times to tens of several times with respect to the volume thereby achieving the sub-miniaturization of the ceramic filter. Also, it is possible to perform the sterilization, deodorization, and the like by forming the carbon layer on the surface of the element or constituting the element layer as the carbon layer. In addition, it is possible to complement the deficient sweet fragrance and the nutrient at the ceramic filter by the natural woody particles, and the reck bed particles, and the like, to perform the sterilization and the deodorization by the activated carbon, and to manufacture the water purifying device with a high capacity into a very compact size.
[41]
