Description
CARTRIDGE FOR FILTRATION AND STERILIZATION OF WATER, INTEGRATED, REPLACEABLE, AND ASSEMBLY FOR THE SAME
FIELD OF THE INVENTION
The present invention relates in general to a cartridge for filtering and sterilizing water, integrated, replaceable, and the assembly for housing thereof, which is capable of removing particulate, organic, inorganic and / or heavy metal materials from a stream of water, while also sterilizing the stream of filtered water to destroy most of the microorganisms, bacteria and viruses contained in it.
BACKGROUND OF THE INVENTION
As environmental agencies are more aware of the potential health risks associated with municipal water or well water, there has been an increasing need for residential water purification that is capable of eliminating organic materials. , inorganic, particulates, microorganisms, bacteria and viruses of the water supply before consumption. REF: 24368 Most conventional systems require a series of filtration and chlorination units to adequately remove such materials from water. These units are extremely expensive to install and maintain, and occupy a large space making them unfit for common use. Filtration media have been used for years to remove particulate materials from the water supply, while carbon block filters have been effective in removing organic and inorganic materials. However, conventional filters are incapable of eliminating microorganisms such as bacteria, viruses, yeast or fungi. Ultraviolet radiation in the 200-300 nanometer range has been extremely effective in killing such microorganisms. As such, germicidal lamps have been used extensively in air and water purification, wastewater treatment, food and beverage protection, and other disinfection and sterilization applications. Recent efforts by filtration manufacturers have resulted in the creation of water purification systems that combine the disinfection and sterilization capabilities of ultraviolet radiation with the capabilities of conventional filtration media for particulate, organic and inorganic materials. The combined system provides extremely pure and sterilized drinking water, regardless of the source of the water source. These two conventional two-stage water purification systems typically include an ultraviolet light lamp attached to the base unit of a filtering housing assembly and protected by a stainless steel jacket or jacket. A conventional carbon block filter is removably slid over the outside of the jacket and then the filter housing is placed over the carbon filter and screwed onto the base. Typically, the ultraviolet light lamp is placed inside a quartz tube and replaceable to the base. Two-stage water purification systems as described above require periodic maintenance such as replacement of the carbon block filter approximately every six months (more frequently if necessary), replacing the ultraviolet light lamp every twelve months to ensure the proper functioning (for example, the lamp can not be burned, but the disinfection capacity does not diminish with time), and the quartz tube must be cleaned every six months. Although the carbon filter block is easy to replace, for example, by simply unscrewing the filter housing and sliding the filter out of the stainless steel sleeve at the open end, replacement of the ultraviolet light lamp requires substantial disassembly of the filter. the base housing unit. Since the replacement of the ultraviolet light lamp is extremely difficult, many end users (for example, housewives) will tend not to replace such lamps as often as necessary. If the lamp is not replaced on a periodic basis, its effectiveness in disinfecting and sterilizing water will decrease over time, thereby imposing a health risk on the uninformed end users. Therefore, it could be highly desirable to have a two-stage water purification system, which allows easy removal and replacement of the filter and ultraviolet light lamp. In this regard, the present inventor has developed a unique, replaceable, integrated filter / sterilization cartridge which is easily and quickly removable from the fi ber housing assembly. This integrated filter / sterilization cartridge comprises the ultraviolet light lamp and the filter member together as a single unit, which can be removed from the base unit of the housing assembly without the need for tools or detailed instructions. In addition, the combination concept of the "filter member and the ultraviolet light lamp in a simple replaceable cartridge, will cause the unsophisticated owner or the end user to replace both elements at the same time, thereby avoiding the inherent risk to the health of leaving an ultraviolet light lamp, of static lighting but less effective inside the filter assembly.

The first end plate 83 comprises at least one permeate side-by-side hole 97 placed therein and in contact with the permeate chamber 93 and the permeate compartment 99. The outer housing 75 is positioned around the cartridge 81 to form a feed chamber 105 between the inner surface 107 of the outer housing 75 and the outer surface 109 of the filtration member 91, and wherein the feed chamber 105 is in contact with the gate means 79, to feed the feed stream towards the montage. This in-line assembly can be easily coupled to a supply current conduit simply by means of bolting means 79 and means 77 to the portions of the conduit, or by any other conventional, removable sealing means, such as snap fit.
Figures 7 and 8 describe yet another embodiment according to the present invention, wherein the second end plate 111 is fixed to the upper portion of the filtration member 27 by any of the aforementioned methods. The second end plate 111 includes an elastomeric portion or gasket 113, which creates a fluid-tight seal between the second end plate 111 and the knife section 115, positioned around the inner surface 37 of the outer housing 5. The gasket 113 is forced against the blade 115 when the lower unit 3 is securely connected to the outer housing 5. According to this embodiment a feed stream enters the base unit 3 via the conduit 117, and passes between the first end plate 119 and the inner surface 37 of the outer housing 5 towards the feed channel 35. The first end plate 119 is fixed to an opposite end of the filter member 27 and includes an elastomeric portion or packing 121, which creates a seal between the first plate 119 and the base unit 3, when the base unit 3 is securely connected to the outer housing 5. The fluid-tight seal is formed by the contact between the package 121 and a blade 123 molded into the base unit 3. The feed stream permeates through the filtration member 27 towards the permeate channel 29, where it is brought into contact with the ultraviolet light radiation emitted of the ultraviolet light lamp 21. The treated permeate passes from the permeate channel 29 through a permeate conduit 125 formed between the first end plate 119 and the outer side wall of the quartz tube 51. After passage through the conduit of permeate 125, the treated permeate passes through a permeate hole 127 into the permeate chamber 129 positioned within the base unit 3. After this, the treated permeate passes out of the base unit 3 via the permeate gate 131. As shown in FIG. shown in Figure 8, it is optional to have a two-pin electrical power source connector 133, placed directly on the end layer 25. Figure 9 is similar to the cartridge shown in Figure 8, except that it includes a sleeve 141 in countercurrent, which comprises a permeable inner layer 143 and an impermeable outer layer 145. The permeable inner layer 143 is typically formed of a permeable material such as plastic or stainless steel wire mesh or non-woven fabric (eg Typar ™) . The impermeable outer layer 145 is typically a waterproof plastic or metal sheet. It is preferable that the countercurrent jacket 141 be wrapped or otherwise placed around the internal surface of the filtration member 27. The countercurrent jacket 141 allows * the permeate to pass through the permeable layer 143 and out of the upper thereof, such that the permeate is required to traverse the full length of the permeate chamber 29, in order to increase its residence time within the permeate chamber 29 before exiting via the permeate conduit 125. Figure 10 describes the base unit 3 and Figure 11 is the top plan view of Figure 10. Figures 12 and 13 are similar to Figure 7, except that the permeate leaves the permeate channel via the permeate gate 151. Also, the first end plate 153 is affixed to the inner surface of the quartz tube 51 via the elastomeric sealing means 23, and the second end plate 155 is open at the end, such that the permeate can pass at through it into the permeate duct 151.
Figure 14 is similar to Figure 12, except that the first end plate 161 is formed of an elastomeric material that is capable of forming a fluid-tight seal between the first end plate 161 and the exterior surface of the quartz tube 51, avoiding in this way the need for gaskets, rings or, insulating washers or the like. Since the second end plate 163 and the first end plate 161 are formed of an elastomeric material, there is no need for gaskets 113 and 121, respectively, since the blades 115 and 123 can create a fluid-tight seal upon contacting. with the first and second end plates (161, 163). In each of Figures 7, 12 and 14 the outer housing 5 and the base unit 3 form a fluid-tight seal therebetween, by means of packing or "0" ring 165.
It is noted that in relation to this date, the best method for the applicant to carry out the aforementioned invention, is the conventional one for the manufacture of the objects to which it refers.
