Description

The invention relates to a pressure vessel with a hermetically sealable container comprising a cavity for receiving a granulate for the chemical and / or physical treatment of a fluid passed through the container, wherein the container has at least one access opening through which the cavity is accessible from outside, and which is configured such that it can be closed from the inside by a closure lid part arranged in the cavity, in that the closure lid part with its closure seat can be pressed against a sealing seat of the filling opening facing the cavity.

Generic pressure vessels are well known in the art, such as an ion exchanger. With such a pressure vessel, for example, a liquid such as water, be prepared or purified by the liquid is introduced into a filled with granules container of the pressure vessel such that the liquid flows around this granulate under pressure before it is removed from the container again. For this purpose, the pressure vessel comprises a multiplicity of connections, such as, in particular, a liquid feed connection, a liquid discharge connection, a dip tube connection, a venting and / or aeration connection or the like.

Alone through this variety of existing connections, the actual container is quite complex. Accordingly, the production of related pressure vessel is correspondingly more expensive.

In addition, a larger filling opening is provided on the actual container, through which the granules can be filled into the container or removed from the container.

In order to be able to reliably close this filling opening also with regard to a container operated under overpressure, a flange part provided with a screw thread is usually provided at the filling opening into which a threaded plug can be screwed. This flange part is often formed by the container wall of the container itself, cast as a separate component in the container or materially connected to this container wall. Typically, the flange member is placed on a container ceiling area to be easily accessible when the container is placed on a base.

Such a flange part, in whatever shape, is relatively complicated to produce. Especially integrating such a flange as an additional component in the container wall is usually very complex and more expensive as the production.

In this respect, pressure vessels exist with other containers, in which such a the filling opening forming flange part is omitted. In this case, structurally simpler a generic filling opening is recessed as a simple material recess in the container wall, wherein the surrounding this filling opening edge region of the container wall is formed on the container inside as a sealing seat. Within the container there is a closure lid part with a closure seat designed to be complementary to the seal seat, which is pressed against the seal seat for closing the filling opening. Thus, the filling opening is closed from the inside pressure-tight by the preferably permanently disposed inside the container closure lid part is pressed with the closure seat against the complementary sealing seat of the filling opening. In order to be able to position the closure lid part with little effort from the inside in front of the filling opening, it is held on a bracket element spanning the filling opening. More specifically, the closure lid part is suspended by means of a rod member penetrating the stirrup element, which is inserted through a bore of the stirrup element, on this stirrup part. The rod part carries a thread on which a threaded nut is screwed in such that the closure cover part can be pulled against the seal seat of the filling opening when the threaded nut is supported when screwed onto the thread of the rod part against the bracket element.

During operation of the pressure vessel, that is, when the container is under pressure, the closure lid part is additionally pressed by this prevailing inside the container overpressure against the seal seat of the filling opening, whereby the container is advantageously designed self-sealing at its filling opening. In this respect, the reliability of the pressure vessel is thereby increased.

Although it is possible to dispense with this complicated structured filler opening on a complicated building flange and the container are built accordingly easier. However, the container wall of the container is still quite complex due to the large number of existing connections.

The invention has for its object to further develop generic pressure vessel, so that at least the above-mentioned disadvantages can be overcome.

The object of the invention is of a pressure vessel with a hermetic closable container comprising a cavity for receiving a granulate for the chemical and / or physical treatment of a fluid passed through the container, wherein the container has at least one access opening through which the cavity is accessible from the outside, and which is designed such that it can be closed from the inside by a closure lid part arranged in the cavity, in that the closure lid part with its closure seat can be pressed against a sealing seat of the access opening facing the cavity, wherein the closure lid part arranged in the cavity comprises a fluid feed opening and / or a fluid discharge opening.

The fact that a fluid supply opening and / or a Fluidabführöffnung are arranged on the closure part, the container can be made structurally simpler, since no or at least less additional openings, connections or the like must be provided in the outer wall of the container.

In this case, the closure lid part arranged in the cavity is preferably designed such that it closes the access opening and thus the cavity of the container in a pressure-proof manner solely by pressurizing the container. In this respect, the present closure lid part against the container outer wall is self-locking.

If the closure lid part arranged in the cavity can be fixed to the access opening by means of a holding and / or clamping device, it can be prepositioned on the container relatively simply and precisely in front of or at the access opening.

Preferably, the closure lid part remains permanently within the cavity of the container. Thus, the closure lid part is undetachable and stored captive inside the container.

It is particularly advantageous if the present closure lid part is compatible with existing containers if it is designed accordingly. As a result, retrofitting existing container with the present cap part is easily possible.

The present hermetically sealable container can be designed differently. Preferably, it is designed as an internal pressure-resistant pressure vessel.

Preferably, the hermetically sealable container comprises a cylinder-like body, which merges at its front-side ends, on the one hand, in a materially closed manner into a ceiling area and, on the other hand, in a materially closed manner into a floor area. In this respect, the container is preferably produced in one piece, wherein this one-piece can also be achieved in that a container upper half connected to a container half, preferably welded, is.

The container or its body can be made of metal or plastic.

Ideally, the ceiling area and the floor area are concave on the inner side facing the cavity in order to better withstand internal pressure.

Preferably, the container has on its upper side a head ring and on its underside a base ring, so that the container by means of the base ring can be steadily placed on a substrate. Using the head ring, multiple containers can be easily stacked on top of each other.

The present access opening is preferably a closable granulate filling opening for filling the granulate into the cavity. This can be provided either in the ceiling or in the bottom area of the container.

At the pressure vessel, different granules for chemical and / or physical treatment of the fluid passed through the container can be used. For example, such granules comprise a resin.

The present fluid is preferably a liquid, such as water.

Preferably, after having passed through the aggregate of granules held in the container, this liquid can be withdrawn from the container through the closure lid member, or vice versa.

For example, as water trickles through or around the granules, it may be desalted, providing very pure water.

In this respect, the pressure vessel can be connected by means of the present closure lid part to a fluid circuit, in particular to a water circuit, without the need for connection sleeves or the like to be present on the outer wall of the container.

The areas of application of the pressure vessel are manifold. For example, the present pressure vessel is used as an ion exchanger in medical fields, in paint shops, in the food industry etc. used to prepare water or the like advantageous.

A preferred embodiment provides that the closure lid part arranged in the cavity comprises a fluid supply connection device for connecting a fluid supply and / or a fluid discharge connection device for connecting a fluid discharge. By means of these connection devices, corresponding connection lines can be connected directly to the closure lid part, so that, for example, a liquid can be supplied through this closure lid part to the cavity of the container.

It is understood that these connection devices can be designed differently. In the simplest case, such a connection device comprises a threaded connector with an external thread onto which a coupling ring of a connector of a connecting cable can be screwed. The threaded connector can also have an internal thread instead of an external thread. Alternatively it can also be provided with a bayonet fitting equipped connecting piece.

The closure lid part arranged in the cavity can also have a dip tube connection device for arranging a dip tube element which can be inserted into the cavity. As a result, it is possible to dispense with a corresponding immersion tube connection device arranged in the container wall, as a result of which the container itself can be produced more easily.

Since generic immersion tube elements and their functions of the prior art are known per se, such a dip tube element is not further described herein.

Advantageously, a head part of a submersible tube element which can be inserted into the cavity is arranged on the closure lid part arranged in the cavity. As a result, the number of openings required on the container outer wall can be reduced.

If a filter device for filtering the fluid is arranged on the closure lid part arranged in the cavity, the closure lid part can take over further functional properties of the pressure vessel with little structural complexity.

For example, the head part of the submersible tube element which can be inserted into the cavity can be fitted well to the closure lid element if the closure lid part arranged in the cavity has at least one internal thread for screwing in a functional part. Such a functional component of the pressure vessel may, for example, be the head part of the immersion tube element, the filter device, a supply and / or discharge connection part, a deaerating and / or ventilating device, or a multifunctional component which performs a plurality of functions, or the like.

In addition, the container of the pressure vessel can be designed more functional if the closure lid part arranged in the cavity comprises a venting and / or ventilating device for venting and / or venting the cavity, since such a vent or vent does not unnecessarily weaken the outer wall of the container.

A particularly preferred embodiment provides that the cavity of the container is accessible only through this access opening or by in the arranged in the cavity closure cover part function openings accessible and connectable to the environment. For this purpose, the container is preferably configured such that the cavity is accessible only by a single opening directly penetrating the container outer wall. In this respect, the container is structurally particularly stable and moreover cheaper than previously produced.

Such a functional opening is, for example, a water supply opening, a water discharge opening and / or an air opening.

In this respect, it is advantageous if the container has an outer wall, in which only one passage opening is arranged. As a result, the container of the present pressure vessel can be made easier.

The closure lid part constructed in the sense of the invention can be designed almost arbitrarily. For example, it has a round base.

In order to be able to advantageously place the most varied connection devices, in particular those described above, on the present closure lid part, it is advantageous if the closure lid part arranged in the cavity has an oval base surface.

In this respect, a plurality of connection devices can be arranged favorably on the closure cover part if at least one connection device of the closure cover part arranged in the cavity is arranged eccentrically on the closure cover part. It is understood that a connection device can also be placed centrally on the present closure lid part, if this is expedient.

The closure cap part can be provided in a structurally simple manner if the closure lid part arranged in the cavity comprises a cast body or an injection-molded plastic body.

Alternatively, the closure lid part can also be produced inexpensively if the closure lid part arranged in the cavity comprises a sheet metal body. As a result, the closure lid part can be produced, for example, as a stamped sheet metal component and / or as a welded construction.

It is also advantageous, independently of the other features of the present invention, for a dip tube element of the pressure vessel to have a pelletizer tip facing the bottom region of the container. Through this Granulatverdrängerspitze the Taurohrelement can be much easier dipped into the filled with granules cavity. The Granulatverdrängererspitze may in this case have a tapered pointed body. Or the main body is hemispherical or the like configured.

Further features, effects and advantages of the present invention will be explained with reference to the appended drawing and the following description, in which different closure lid parts which can be arranged in an ion exchanger container and which each have a fluid supply connection device enabling a fluid supply opening are shown and described.

The in 1 shown pressure vessel 1 for the chemical and / or physical treatment of water has a hermetically sealable, one-piece container 2 on, whose cylinder-like body 3 at its front ends 4 respectively. 5 on the one hand cohesively in an upper ceiling area 6 and on the other hand cohesively in a lower floor area 7 passes. This body 3 is made of metal. The container 2 limits a cavity 8th of the pressure vessel 1 which by one in the ceiling area 6 of the cylinder-like body 3 as material recess 9 recessed access opening 10 is accessible from the outside. In the cavity 8th there is a granulate, not shown here, for the chemical and / or physical treatment of the water. For this purpose, the water in a known manner through that in the cavity 8th passed granules.

In this first embodiment, the access opening 10 executed oval and through them is immediately a Granulateinfüllöffnung 11 for filling the granules into the cavity 8th embodies.

At the ceiling area 6 is a head ring 12 made of plastic.

The access opening 10 is the only opening in the outer wall 13 of the container 2 is realized.

In that sense, the cavity 8th even only through this single access opening 10 accessible from outside.

The access opening 10 is by a deep-drawn collar 14 so limited that the access opening 10 through one of the cavity 8th facing sealing seat 15 is bordered.

The access opening 10 can in this case with different closure lid parts 20 (see. 2 to 5 ) 120 (see. 6 ) or the like are sealed pressure-tight. These closure lid parts 20 . 120 are always inside the container 2 So in its cavity 8th arranged.

The pressure vessel 1 is an ion exchanger in this first embodiment 1A ,

According to the representations after the 2 and 3 is a first embodiment of a closure lid part 20 shown having an injection-molded plastic body 21 having. The closure lid part 20 has an oval base 22 on which of the oval shape of the access opening 10 of the container 2 equivalent. In addition, the closure lid part 20 a lock seat 23 on which is complementary to the sealing seat 15 the filling opening 10 is. At this lock seat 23 a sealing element (not shown here) may be arranged. This lock seat 23 is encircling at a border area 24 of the closure lid part 20 arranged. In this respect, the filling opening 10 by means of within the container 2 arranged closure lid part 20 be sealed pressure-tight when the closure lid part 20 with his lock seat 23 from below against the sealing seat 15 is pressed. This can, for example, by a correspondingly high pressurization within the cavity 8th be achieved. In the closure lid part 20 are immediately two connection devices 25 and 26 arranged. The connection device 25 is in this embodiment as Wasserzuführanschlusseinrichtung 25 for arranging a multifunction module (see 4 ) or the like. The further connection device 26 is a Wasserabführanschlusseinrichtung 26 for connecting a water drainage (not shown).

As in particular according to the illustration of the 2 is clearly visible, are both the Wasserzuführanschlusseinrichtung 25 as well as the water drainage device 26 eccentric on the closure lid part 20 arranged so that these on the oval base 22 spatially advantageous can be arranged.

In any case, the closure lid part 20 immediately at least one Wasserabführöffnung 27 on, by means of which previously via a Wasserzuführöffnung 51 (see. 4 ) in the cavity 8th introduced water through the cap part 20 through again out of the container 2 can be dissipated. The corresponding water supply opening 51 For example, in the multifunction module 50 (please refer 4 ) or the like, so that in this embodiment, the water to be purified also through the closure lid part 20 is passed through to the cavity 8th to get. In particular, a screw seat 28 the Wasserzuführanschlusseinrichtung 25 on the closure lid part 20 to be able to train, has the cast body 21 a sufficient height 29 on which is between a subordinate 30 and a top 31 of the closure lid part 20 extends. The height 29 is at least 1/10, preferably 1/7 of the amount of the long side 32 of the oval cap part 20 to thereby a sufficiently stable internal thread 33 the Wasserzuführanschlusseinrichtung 25 to realize in which the appropriately designed multifunction module 50 can be screwed to it on the closure lid part 20 solvable, but fixed. The long side 32 is in this embodiment 100-120 mm, preferably 112 mm, while not explicitly marked here short side of the closure lid part 20 only 80-110 mm, preferably 96 mm, measures.

The Wasserabführanschlusseinrichtung 26 characterized by a connecting piece 35 out, which outwards over the top 31 of the closure lid part 20 protrudes. The connecting piece 35 carries an external thread 36 to which a not shown here coupling ring of the water drainage can be screwed, thus the water drainage or a water discharge line directly to the closure lid part 20 to fix. The through the Wasserabführanschlusseinrichtung 26 directly on the closure lid part 20 realized water discharge opening 27 has a discharge channel 37 on, starting from the bottom 30 of the closure lid part 20 towards the top 38 of the connecting piece 35 so rejuvenated that the narrowest point 39 the discharge channel 37 in the area of external thread 36 or the exit 40 the discharge channel 37 is present. This allows the Wasserabführanschlusseinrichtung 26 such on the closure lid part 20 be formulated that a conventional coupling ring of water drainage to the water drainage device 26 can be connected. At the entrance 41 the discharge channel 37 can be connected to a drain pipe, not shown here, which is within the cavity 8th to the bottom area 7 is enough to suck the water leaked by the granules and this through the cap part 20 through to the outside again.
