B. extendable and lockable pull handle. The illustrated parcel shipping unit ( 10 ) is closed and for example by means of a seal ( 15 ) secured against unauthorized opening. On the trunk lid ( 13 ) is in the representation of 1 an address label ( 16 ) glued.

The shipping case ( 11 ) is sealed, for example, dustproof. The interior ( 17 ) of the shipping housing ( 11 ) is protected against moisture when immersed in water. Between the case ( 12 ) and the trunk lid ( 13 ) is in the representation of 3 a sealing element ( 18 ) arranged. Furthermore, the shipping case ( 11 ) a pressure compensation device ( 19 ) in order to reduce the pressure in the interior ( 17 ) to the pressure of the environment ( 1 ).

The case shell ( 12 ) and the trunk lid ( 13 ) form a housing wall ( 21 ) of the shipping housing ( 11 ). The area of the housing wall ( 21 ) on which the carrying handle ( 14 ) is hereinafter referred to as the end wall ( 22 ) designated.

At the end wall ( 22 ) are in the exemplary embodiment four the housing wall ( 21 ) penetrating execution units ( 31 ) attached. For example, the execution units ( 31 ) each have an external thread ( 32 ) by means of two hexagon nuts ( 33 . 34 ) in the interior ( 17 ) and on the outside of the shipping housing ( 11 ) is fixed, cf. the 2 and 3 , Furthermore, on the end wall ( 22 ) an electrical connection ( 23 ) can be arranged. All execution units ( 31 ) are completely within the envelope contour of the shipping housing ( 11 ) arranged. The envelope contour is the z. B. cuboid contour, the outer surfaces of the shipping housing ( 11 ). If necessary, the execution units ( 31 ) in depressions of the shipping housing ( 11 ) to sit. In the exemplary embodiment, the execution units ( 31 ) Also within a Hüllkontur whose corners are formed obliquely or rounded.

The 2 shows a sectional view of the housing wall ( 21 ) with the implementation units ( 31 ). In the 3 is the shipping case ( 11 ) with opened trunk lid ( 13 ). The 4 shows, for example, details of a plan view of the end wall ( 22 ).

The execution units ( 31 ) are parts of a fluid treatment device ( 30 ), whose device housing ( 11 ) through the shipping housing ( 11 ) is formed. The 5 shows an example of the circuit diagram of a fluid treatment device ( 30 ). Such liquid treatment devices ( 30 ) are used to remove impurities from a liquid. The thus purified, purified liquid can then be used for purposes for which the original, contaminated liquid would be detrimental. The liquid can z. As water, oil, hydrocarbon, etc. be. In the embodiment, water is used as the liquid.

The execution units ( 31 ) are in the embodiment a liquid inlet unit ( 35 ) and three exit units ( 36 ). In the exemplary embodiment, the outlet units ( 36 ) a filter outlet unit ( 37 ), a concentrate outlet unit ( 38 ) and a permeate outlet unit ( 39 ). The shipping case ( 11 ) has at least one outlet unit ( 36 ) on. In one embodiment of the shipping housing ( 11 ) with a single outlet unit ( 36 ) this is a filter outlet unit ( 37 ). Indicates the shipping case ( 11 ) two exit units ( 36 ), for example, the one outlet unit ( 36 ) a concentrate outlet unit ( 38 ) and the other outlet unit ( 36 ) is a permeate outlet unit ( 39 ). Also an embodiment with a filter outlet unit ( 37 ) and a Mischflüssigkeitsauslasseinheit is conceivable.

The liquid inlet unit ( 35 ) has an inlet coupling element ( 41 ) and in the housing interior ( 17 ) arranged check valve ( 42 ), see. 5 on. The inlet coupling element ( 41 ) is a drip-free lockable quick-release element ( 41 ). It has a receiving recess ( 43 ), which is for example non-cylindrical. In the presentation of the 4 has the receiving recess ( 43 ) of the inlet coupling element ( 41 ) a z. B. semicircular Codierausnehmnung ( 44 ) as well as a centripetally oriented centering nose offset by 45 degrees thereto ( 45 ). Also another embodiment of the receiving recess ( 43 ) is conceivable.

In the inlet coupling element ( 41 ) is a closure valve ( 46 ) integrated. This has, for example, a valve disc ( 47 ), which in the uncoupled state, the bottom of the receiving recess ( 43 ) closes. The valve disc ( 47 ) is by means of a compression spring ( 48 ) in the closing direction ( 49 ) charged. From the closed position is the valve disc ( 47 ) against the closing direction ( 49 ) and against the spring force of the compression spring ( 48 ) axially displaceable. This is done for example by means of a in the receiving recess ( 43 ), complementarily coded Zuführanschlussstücks ( 101 ), z. B. a plug ( 101 ). In this displacement of the valve disc ( 47 ), the closing valve ( 46 ) unlocked. The inlet coupling element ( 41 ) is opened, cf. 2 , The inlet coupling element ( 41 ) can additional locking elements ( 51 ) to the inserted plug ( 101 ) to fix. A fixation by means of a screw or bayonet protection is conceivable. Also the plug ( 101 ) can be formed with an openable during insertion plug valve.

The Z. B. spring-loaded check valve ( 42 ) is in the flow direction ( 91 ) the inlet coupling element ( 41 ) downstream. It opens in the flow direction ( 91 ) and locks in the opposite direction.

The filter outlet unit ( 37 ) is similar to the liquid inlet unit ( 35 ). As the 4 shows, the receiving recess ( 53 ) of the filter coupling element ( 52 ) an encoding that is not congruent with the coding of the inlet coupling element ( 41 ). The in the filter coupling element ( 52 ) plug-in outlet connector ( 102 ) is thus only with this outlet coupling element ( 52 ) can be coupled.

The check valve ( 54 ) of the filter outlet unit ( 37 ) is the filter coupling element ( 52 ) in the flow direction ( 91 ) upstream. Also this check valve ( 54 ) is spring loaded. It opens in the direction of flow ( 91 ) and closes in the opposite direction.

The concentrate outlet unit ( 38 ) and the permeate outlet unit ( 39 ) including associated check valves ( 55 . 56 ) are constructed as the filter outlet unit ( 37 ). In the 2 is the permeate outlet unit ( 39 ) with closed closing valve ( 57 ). The coding of the receiving recesses ( 58 ) is designed such that the associated plug only in the respectively associated coupling element ( 59 ) can be used.

At the end wall ( 22 ) in the exemplary embodiment, the electrical connection ( 23 ) arranged. This is designed, for example, as an internal plug for connecting the socket of a low-voltage direct current source. The voltage source provides, for example, a current of 5 amps and a voltage of 12 volts or 24 volts. The electrical connection ( 23 ) is z. B. dustproof and waterproofed against immersion in water. In the exemplary embodiment, the electrical connection ( 23 ) as reverse polarity protection a cam ( 24 ). The shipping case ( 11 ) can also be used without electrical connection ( 23 ) be formed.

In the interior ( 17 ) of the device housing ( 11 ) In the exemplary embodiment, a booster pump ( 61 ), a mechanical prefilter device ( 63 ), an adsorption filter device ( 64 ), a membrane filter device ( 68 ) as well as a mechanical superfine filter device ( 83 ) arranged. The fluid treatment device ( 30 ) can also be used without the booster pump ( 61 ), the prefilter device ( 63 ), the membrane filter device ( 68 ) and / or the ultra-fine filter device ( 83 ).

In the presentation of the 5 is the booster pump ( 61 ) of the liquid inlet unit ( 35 ) downstream. The booster pump ( 61 ) is, for example, a gear pump, which increases the pressure of the incoming liquid to, for example, 4 × 10 ⁵ Newton per square meter (4 bar). The booster pump ( 61 ) can be electrically driven. For example, it is with the electrical connection ( 23 ) connected. Also, a manually operated drive, for. B. by means of a hand crank or the drive by means of a dynamo, etc. is conceivable. Also, the booster pump ( 61 ) be designed such that they are both electrically and -. B. in the absence of electrical energy - is manually driven. The booster pump ( 61 ) may be preceded by a dirt filter.

In the line ( 92 ) is still the shut-off valve of a leakage sensor ( 62 ) arranged. Exceeds, for example, the moisture content of one in the device housing ( 11 ) a limit value, the shut-off valve locks the line ( 92 ).

The booster pump ( 61 ) is in the flow direction ( 91 ) the mechanical prefilter device ( 63 ) downstream. The prefilter device ( 63 ) comprises in the exemplary embodiment a filter housing with a sediment filter inserted therein. This has z. B. a filter area of half a square meter and a filter fineness of 5 to 10 micrometers. The fillet fineness of the prefilter device ( 63 ) is greater than 1 micron and less than 50 microns. The filter element is made of stainless steel, a thermoplastic, etc., for example. For example, at a flow rate of 40 liters per minute, it causes a pressure drop of 10 ³ newton per square meter (0.01 bar). It is also conceivable to design the sediment filter in multiple stages with increasing filter fineness in the flow direction. For example, then the average filter fineness of the prefilter device ( 63 ) in the above interval. The prefilter device ( 63 ) can be made flushable.

In the flow direction ( 91 ) follows the prefilter device ( 63 ) the adsorption filter device ( 64 ). This includes, for example, an activated carbon filter inserted in a filter housing. Also, the adsorption filter device ( 64 ) Have a downstream of the activated carbon filter postfilter and optionally a pre-filter. The activated carbon filter can be flowed through axially or radially. The adsorption material may be formed as a carbon granulate or as a carbon block. When flowing through a liquid to store organic and inorganic impurities, eg. As odors, flavors, bacteria, etc. to the activated carbon filter. The pre-filter is made for example of a polyester fleece. The postfilter is z. B. from a made thermoplastic material and has a filter fineness of, for example, 5-10 microns. In one embodiment of the activated carbon filter of a porous coal block this can be carried out without pre-filter and without post-filter. Also another embodiment of the Adsorptionsfiltervorrichtung ( 64 ) is conceivable.

In the adsorption filter unit ( 64 ) can also be integrated into the activated carbon filter downstream Feinstfilter. This has for example a filter fineness between 0.25 micrometers and 0.1 micrometers.

In the exemplary embodiment, the filter output ( 65 ) of the adsorption filter device ( 64 ) with a tee ( 66 ) connected. Another connection of this tee ( 66 ) is connected to the check valve ( 54 ) of the filter outlet unit ( 37 ) connected. In one embodiment of the fluid treatment device ( 30 ) with a single outlet unit ( 36 ) the tee ( 66 ) accounted for. The filter output ( 65 ) is then directly with the Filterauslasseinheit ( 37 ) connected. The filter outlet unit ( 37 ) may additionally be preceded by a micro-filter for cleaning the filtered water. This has for example a filter fineness between 0.01 microns and 0.05 microns. For example, a filter fineness of 0.02 microns is selected for the superfine filter. Also, between the Adsorptionsfiltervorrichtung ( 64 ) and the superfine filter or the filter outlet unit ( 37 ) may be arranged a pressure accumulator.

To the third port ( 67 ) of the tee ( 66 ) is in the in the 5 illustrated water treatment device ( 30 ) in the flow direction ( 91 ) the membrane filtration device ( 68 ) connected. The membrane filter device ( 68 ) is in the embodiment a reverse osmosis device ( 68 ). This comprises a membrane unit ( 69 ), a permeate check valve ( 76 ), a shut-off valve ( 77 ) and a flow relief valve ( 81 ).

The membrane unit ( 69 ) is arranged in a container. In the container, a fine-pored membrane ( 71 ) a first liquid space ( 72 ) from a second liquid space ( 73 ). In the exemplary embodiment, the absolute value of the filter fineness of the membrane ( 71 ) 5 microns. The first fluid space ( 72 ) is in the embodiment of the tee ( 66 ) downstream. The z. B. made of polyamide membrane ( 71 ) is designed, for example, for a flow rate of 15 liters per hour and requires a pre-pressure of 3.4 bar.

The output connector ( 74 ) of the first liquid space ( 72 ) is connected to the shut-off valve ( 77 ) connected. The shut-off valve ( 77 ) has two parallel flow paths ( 78 . 79 ), which are hermetically separated hydraulically. The output connector ( 74 ) is at the first flow path ( 78 ) connected. The second fluid space ( 73 ) is connected via a second output terminal ( 75 ) with the second flow path ( 79 ) connected. In the shut-off valve ( 77 ), the second flow path ( 79 ) to a flow-dependent switch whose signal blocks or releases the first flow path. For example, when a maximum pressure value is exceeded or when a minimum flow value in the second flow path is undershot ( 79 ), the first flow path ( 78 ) blocked. The blocking takes place, for example, in the case of a sealed permeate outlet unit ( 39 ).

In the first flow path ( 78 ) is the shut-off valve ( 77 ) a flow-limiting valve ( 81 ) downstream. This can be set, for example, to a flow rate between 350 milliliters and 1200 milliliters per minute. In the embodiment, it is set to a value of 500 milliliters per minute. The maximum flow rate of the flow control valve ( 81 ) may be preset within the aforementioned interval. But it is also conceivable that this limit value in the water treatment device ( 30 ) is infinitely or in stages adjustable. For this purpose, for example, on the end wall ( 22 ) of the device housing ( 11 ) may be arranged an adjusting device. The flow control valve ( 81 ) is in the flow direction ( 91 ) the concentrate outlet unit ( 38 ) downstream.

In the second flow path ( 79 ) is the shut-off valve ( 77 ) in the flow direction ( 91 ) a pressure vessel ( 82 ) downstream. This has in the embodiment, a volume of five liters.

To the outlet of the pressure vessel ( 82 ) is the Feinstfiltervorrichtung ( 83 ) connected. The ultrafine filter device ( 83 ) has a filter housing with a surface filter inserted therein. This has, for example, a filter area of half a square meter and z. B. formed as a folding element. It can be made of cellulose polyester, polypropylene, glass fiber or other filter material. The filter fineness of this ultrafine filter is between 0.01 microns and 0.05 microns. In the exemplary embodiment, the filter fineness is 0.02 micrometers. To the filter outlet ( 84 ) of the ultra-fine filter device ( 83 ) is the permeate outlet unit ( 39 ) connected.

Also another structure of the liquid processing apparatus ( 30 ) is conceivable. For example, instead of the described membrane filter device ( 68 ) a chemical treatment device for the supplied liquid in the device housing ( 11 ) can be arranged. In this treatment, the composition of the liquid by adding Chemicals or by filtering over chemically active substances. For example, this can be done by the method of flocculation, precipitation, oxidation or ion exchange.

In the device housing ( 11 ) may alternatively be arranged an electrochemical treatment device. By means of the electrical connection ( 23 For example, a DC electrical voltage is applied to an electrolytic cell. This can z. B. fed seawater into fresh water, concentrate and saline solutions are decomposed. The individual liquids are separated by means of different, for example coded Auslasseinheiten ( 36 ) from the device housing ( 11 ).

In the device housing ( 11 ) can also be a membrane filtration device ( 68 ), a chemical treatment device and an electrochemical treatment device. All of these aftertreatment devices are z. B. parallel to each other of Adsorptionsfiltervorrichtung ( 64 ) and pass the treated water through its own outlet ports ( 36 ) from the device housing ( 11 ). Each outlet port ( 35 ) can be done by inserting a plug ( 101 ; 102 ) to be activated. For example, by the formation of an output-side pressure sink, the corresponding aftertreatment device is activated. The parcel shipping unit ( 10 ) with the device housing ( 11 ) may also have differently constructed devices ( 30 ) for liquid processing.

During assembly of the liquid treatment device ( 30 ) are the individual components in the device housing ( 11 ) built-in. The liquid inlet unit ( 35 ) and the outlet units ( 36 ) point to the outside and are optionally closed by means of protective caps. If necessary, the device housing ( 11 ) are additionally fed. Then the device housing ( 11 ) locked. If necessary, it can be sealed with a seal ( 15 ). For example, after sticking an address label ( 16 ) on the device housing ( 11 ) serves as a shipping case ( 11 ). The parcel shipping unit ( 10 ) can now be delivered to the customer via a parcel service.

The operator places the parcel shipping unit ( 10 ) on the ground, for example. Without the shipping case ( 11 ), he closes a z. B. initially shut off pressurized water line by means of Zuführanschlussstücks ( 101 ) to the inlet coupling element ( 41 ). Optionally, a coupling under pressure is possible. In addition, the operator closes an outlet fitting ( 102 ) z. B. to the outlet coupling element ( 52 ) of the filter outlet unit ( 37 ) at. The coding of the connections ( 41 . 101 ; 52 ; 102 ) prevents incorrect operation. When coupling the quick couplings ( 41 . 101 ; 52 . 102 ), the integrated shut-off valves ( 46 ; 57 ) open. To the execution units ( 31 ) connected hose lines ( 103 ) are now with the water treatment device ( 30 ) hydraulically connected. The electrical connection ( 23 ) is not connected to a power source, for example.

After unlocking the pressurized water line flows z. B. contaminated water from the pressurized water line through the - stationary - booster pump ( 61 ) into the mechanical prefilter device ( 63 ). Here are z. B. filtered out sediments. The prepurified water is introduced into the adsorption filter device ( 64 ), where organic and inorganic substances are separated from the prepurified water.

The by means of the adsorption device ( 64 ) filtered water now enters the tee ( 66 ). The opened filter outlet unit ( 37 ) forms a pressure sink, so that the filtered water through the filter outlet unit ( 37 ) flows out.

For example, if the customer requires higher quality water, he / she will connect one plug-type outlet fitting to each permeate outlet unit ( 39 ) and to the concentrate outlet unit ( 38 ). For example, the outlet fitting is removed from the filter outlet unit (FIG. 37 ) pulled out. Here, the closing valve ( 57 ) of the filter outlet unit ( 37 ) by means of the integrated compression spring ( 85 ) blocked.

The water now flows out of the adsorption filter device ( 64 ) into the membrane filter device ( 68 ). In this case, the water pressure may be greater than the required osmotic pressure. Optionally, to increase the water pressure, the booster pump ( 61 ) by connecting the electrical connection ( 23 ) are turned on to a power source. The booster pump ( 61 ) can also be used directly in the membrane filter device ( 68 ) upstream.

In the membrane filter device ( 68 ) there is a reverse osmosis, whereby the flow-limiting valve ( 81 ) in the first passageway ( 78 ) maintains the pressure for the reverse osmosis. The contaminated concentrate leaves the device through the concentrate outlet unit ( 38 ). The purified water flows through the second passageway ( 79 ) in the pressure vessel ( 82 ). After leaving the pressure vessel ( 82 ) it flows through the ultrafine filter device ( 83 ) and reaches the permeate outlet unit ( 39 ). Here it can be z. B. be used as drinking water or as hygienically pure water.

If at the permeate outlet unit ( 39 ) no water is withdrawn, the pressure in the second flow path increases ( 79 ) at. The flow of the concentrate is interrupted, which stops the reverse osmosis.

Are all three connections of the outlet units ( 36 ), both filtered water and purified water can be taken. For example, this can be done by means of in each case a secondary-side stopcock or throttle valve in the of the parcel shipping unit ( 10 ) leading away. Each line is assigned a liquid quality.

For example, after a predetermined time interval, for. After six months, the filters of the filter devices ( 63 . 64 . 68 . 83 ) to clean or replace. The customer removes the feed connector ( 101 ) from the inlet coupling element ( 41 ) and all outlet connectors ( 102 ) from the outlet coupling elements ( 52 . 59 ). The coupling elements ( 41 . 52 . 59 ) close automatically, so that no residual water drips. The customer addresses z. B. by means of an address label ( 16 ) the parcel shipping unit ( 10 ). By means of a parcel service, he can send this parcel shipping unit ( 10 ) z. B. return to the manufacturer and receives, for example in return a new or cleaned parcel shipping unit ( 10 ) with a liquid processing device ( 30 ).

Since all coupling elements ( 41 . 52 . 59 ) within the envelope contour of the stable shipping case ( 11 ), there is no risk of damage to the components of the device during shipping. The seal ( 15 ) secures the parcel shipping unit ( 10 ) additionally against unauthorized opening.

Combinations of the individual embodiments are conceivable.
