    The invention relates to a transportable device for gravitational filtration of water to provide drinking water, with a device housing having a filter assembly, in particular a device which is filled with konta¬miniertem water, which is subsequently filtered by gravity to rei¬nem drinking water.
    There are some known solutions of transportable devices for gravitational filtration, most of them are geostationated, d. H. stationary devices. A known solution for transportable gravity filtration of contaminated water to pure drinking water is disclosed in US 7,862,720 B2. According to this document, the gravitational filtration is passed through the housing of the device via a feed channel along the entire device. The channel contains filter inserts which are exchanged when the water flow through the filters has been re¬duced or when the filters are clogged. The device ends with a mouthpiece or outlet for the purified water and may include a prefilter assembly of liners with a possibility for a storage chamber forming the filter system. The storage chamber may be an expandable bellows adapted to be coupled to the transportable device.
    From US 6,625,929 B1 filters are known which aufwei¬sen a ceramic housing and are filled inside with granulated activated carbon. They are used in various variants in filter devices.
    In the device according to US Pat. No. 7,862,720 B2, the use of chemical filter elements with chlorine or iodine is also possible. Typically, the pore of a carbon filter is between 0.35 and 0.45 microns in size. The solution is impractical from the point of view of filter replacement, since replacement of the filter system or of a single filter in the form of filter inserts is necessary in order to be able to perform the filtration undisturbed or in a secured quality.
    Another solution for filtering contaminated water to pure water is known from US 7,507,338 B2. The solution does not allow Gravitationsfiltrati¬on, since the water is fed with a pressure pump of a series of filters.
    US Pat. No. 8,313,644 B2 discloses a solution for filtering contaminated water in the form of a bottle with an integrated filter arrangement, which is actuated by means of a push or pull lever or rod. The liquid is filled through a hollow rod, in the compressed bottle the water is then filtered by pushing the lever or rod with the aid of compression through the closed bottle bottom so that the filtered water rises up the tube along the double inner walls of the bottle flows to the user and the user can drink the purified water. The pressure in the bottle supplied by the push lever is the driving force for the filtration.
    The object of the invention is to form a device of the type described so compact that on the one hand it can be designed easily transportable and on the other hand has a low-cost self-cleaning function.
    The invention solves this problem with the characterizing features 1 and 7.Vorteilhafte further developments of the invention are gekenn¬zeichnet in the dependent claims.
    With the invention, a gravitational filter device is provided, which has a Selbst¬reinigungsfunktion. The self-cleaning is done in particular by flushing back the device with water present in the device. The apparatus for gravitational filtration of the water can be used several times without it being necessary to replace the respective filter system or individual filters manually.
    The problem with the gravitational filtration of contaminated water into pure drinking water is solved according to the invention in that frequent replacement of the filter arrangements is not necessary, since the apparatus has a self-cleaning function which is likewise based on gravitational filtration, which is contaminated in one of the filtration Water of opposite direction acts.
    In the drawing, the invention is Darge¬ at Fland an embodiment. Show it:
    Figure 1: a device according to the invention in cross section in filter position and
    FIG. 2 shows the device from FIG. 1 in a position rotated by 180 ° for flushing out the filter arrangement with returning, filtered water for self-cleaning of the filter arrangement.
    Fig. 1 shows u. a. the water-impermeable device housing G. The Vor¬richtung in the embodiment has a height of 560 mm and a diameter of 110 mm, where it is assembled in the form of a cylinder. The erfin¬Dungsgemäße device comprises a plurality in the inner part of the device housing G interconnected filter assemblies. The first filter arrangement functions as a pre-filter arrangement known in the art.
    The second filter arrangement removes the large coarse particles, the third Filterano¬rdnung removes colloidal particles, microorganisms and pyrogens, the fourth Filteran¬order removes the finest particles, which, if still present in the water, can be harmful.
    The device comprises a water inlet 1 to which a threaded ring 2 and a pre-filter 3 of nylon join. The threaded ring 2 serves to fix the prefilter 3 and the charcoal filter 4 in the housing G. By turning the threaded ring in the clockwise direction, the ring 2 moves in the thread against the pre-filter 3 and the
    Carbon filter 4 and pushes and presses the pre-filter 3 and the carbon filter 4 against a perforated disc 5. The carbon filter 4 consists of a higher pack of carbon foam. The perforated PE disc 5, holds the carbon filter 4 back and allows vor¬ purified water in a first chamber 6 through. In the first chamber 6 there is a filter 7, in particular a longitudinal filter made of ultrafiltration fibers. At the bottom of the wall 8 of the first chamber 6 there is an O-ring 9 over which a sleeve is supported on a cutting disc 10 which separates the first chamber 6 from a second chamber 13. The filter 7 is attached via an O-ring 11 to the Trennscheibe 10, in particular screwed to it. At the Trennscheibe10 is in the adjoining chamber 13, a further filter 13, a nanofilter, another O-ring 11 attached to the blade 10, in particular ver¬schraubt. The second chamber 13 is provided with an outlet 14 for discharging purified water of a device. At the bottom of the second chamber 13 can still od a check valve or a switching valve. Like. For flow control or. Control of the pure water or to shut off the outlet vorgese¬hen be.
    The nylon prefilter 3 is a syntetic coarse pre-filter arrangement and consists of non-deformable fibers of nylon 6 / nylon 66, which is used in the food industry, pharmacy and cosmetics. The pore size is 300 microns, the binding of the material is single-row.
    The carbon filter 4 is made of carbon foam, d. H. Activated carbon with pore sizes from 2 to 50 nm. By adsorption, all chemical contaminants are removed from the water, since the molecules adhere to the active surface in the gaseous or liquid state. This proceeds in such a way that in the case of macro transport, the organic material travels over the macropores of sizes up to 50 nm, whereas during microtransport it moves over the meso- and micropores of the activated carbon.
    The micropores are of the order of 2 nm and the mesopores of 2-50 nm. During sorption, the organic material physically adheres to the activated carbon surface in the meso- and micropores, and the level of sorption activity depends on the concentration of substances, i. H. of impurities in the water, the water temperature and the electron charge of the molecules.
    The filter 7 of ultrafiltration fibers separates the dissolved molecules according to their size or molecular weight. The ultrafiltration fibers in the filter are a hard, thin and selectively permeable membrane with pore sizes of 0.01 microns, which retains the majority of molecules, including colloids, microorganisms and pyrogens.
    The nano-filter 12 with electropositive charges is an excellent filtration medium with a unique combination of high efficiency, capacity, flow and minimum pressure drop. The fibers retain a wide range of contaminants such as bacteria, viruses, DNA, endotoxins, heavy metals and other organic or inorganic contaminants.
    Fig. 1 illustrates the process of gravitational filtration of contaminated water to a water. The water flows through the water inlet 1 through the nylon prefilter 3, which is a polypropylene mesh, with larger particles being retained. As a result of the gravitational force, the water continues to flow through the filter 4, which consists of activated carbon foam, whereby the chemical contaminants are removed from the water by absorption. The water then flows into the first chamber 6 and thence through the filter 7 composed of ultrafiltration fibers whose ultrafiltration fibers act like a molecular sieve. In the first chamber 6, all particles larger than 0.01 microns are retained, thus removing from the water microorganisms including colloidal particles and pyrogens. The thus purified water then continues to pass through the Na¬ nofilter 12, which is composed of a high electropositive charge, nanofibers and ends up in the second chamber 13. In this phase, heavy metals, endotoxins, viruses and other organic or inorganic Contaminants removed.
    For self-cleaning of the device according to the invention, the device is rotated by 180 ° about a horizontal axis, whereafter the water present in the device rinses the filter arrangement by means of the gravitational force. The water remaining in the apparatus flows through the gravitational force in the reverse direction through the filter assemblies in the apparatus and through the opening through which the contaminated water was previously filled. In this step, the filter assembly is automatically backwashed in the device, whereby the device is ready for further filtration. When the wastewater to be purified flows through the device, it flows through various layers or different filtration media; that is, the water in the device is cleaned differently at different stages simultaneously. When the device is rotated 180 °, the variously purified waters flow through the filters and clean them. At the top of the device or behind the nanofilter 12 is located in the self-cleaning the most thoroughly purified water, which rinses all last filter arrangements. Behind the carbon filter 4 is the water which has been purified only with the carbon filter 4, and this water first returns in the opposite direction through the carbon filter 4. Thereafter, the water flows out of the first chamber 6 and then the water from the second chamber 13 through the carbon filter 4 from the device. It is essential that each filter or filter assembly, irrespective of the pores, be flushed out with water in this gravitational manner.
    The portable device operates on a gravity and flyscopy basis and does not require additional power to operate. Such purified water surpasses the most demanding health standards in the world. The device may convert a microbiologically and chemically contaminated source of water to pure drinking water.
