Description

METHOD AND DEVICE FOR CARBONIZING A LIQUID, PREFERABLY LINE WATER

The invention describes that carbonizing within one or more pump housing, preferably Co ² with water.

The tap water pressure is increased by at least one fluid pressure increase pump and is forced under high pressure into a so-called carbonator kettle or pot. Addition of Co ² can carbonize. However, this always takes place by increasing the pressure within the Karbonatorkessels. So, you have to increase the fluid pressure. Such a type of carbonization is mainly used in the dispensing industry for water dispensers and post-mix systems.

In this type of carbonating via a carbonator, mainly applied models, such as counter units with intregated cooling for tap water and syrup refrigeration, undercounter appliances with cooling for tap water and syrups, and circulating carbonators.

The so-called circulatory carbonators are also available to allow at least one, in technical terms, python to be used. The so-called Pyton is nothing else, for example: syrup lines and gas line and still water line and also carbonation line, bundled and isolated from the carbonator to connect to the tap. In such an application, a carbonator kettle, tap water and Co ^{2 are} carbonated via a booster pump within the boiler and this carbonated water is circulated. This carbonated water, with the help of a circulation pump, always in the direction of the taps, in a circuit, kept in motion and runs over and over again a cooling for liquids to keep the carbonated water at an ideal tapping temperature to produce post-mix drinks , In the prior art, in the aforementioned principle, two pumps are needed, a booster pump to carbonize, and a Kreislauφumpe to keep carbonated water in circulation. One of these pumps can also operate the still water cycle to recycle non-enriched tap water around this still water circuit, which is also used primarily for cooling syrup or used to mix carbonated water with still water or To maintain a cycle for carbonated liquids, which has the same above-mentioned aspect. Return line or lines, which in turn preferably with the circulation pump or pumps: Verdrängeipumpe, is connected and provided with at least one additional outlet to preferably: Inline carbonator or carbonators with liquids to supply.

When the tapping process is finished, carbonation is no longer possible. Because up to the taps, a pressure equalization has taken place and now the liquid is circulated only in the still water and carbonated water circulation. Also, the new fluid supply then rests from the main water supply, towards the pump. In the return line at least one Rückflüssveiiiinderer is used or interposed to flow nachströmt water flowing from the main supply is forced to flow in the direction of the pump to guarantee the flow direction pump suction. Also, at least one pressure regulator should be provided between the main supply line for the liquid and the pump, which if possible also cleans the liquids before a filter system. The aforementioned stillwater cycle can also be used to, for example, also supply two or more preferred in-line carbonators with liquids to utilize the pressure drop within the lines to carbonize.

The inventive solution, is that one within a pump housing or more pump housing during operation of the pump, preferably carbonized

In the aforementioned prior art, are mainly positive displacement pumps in use such as: the pump from the company Maprotec, which consists of a brass housing or VA steel housing. These types of pumps are mainly used as a booster pump to, for example: fill a carbonator with water in the entrance area, for water. The boiler is usually attached to one of these, which creates a backwater to the pump. This back pressure causes the pump to do so because it can not displace the amount of water offered, but to maintain it by increasing the pressure inside the pump casing because the water can not be compressed, the space between the static component and the mechanical parts of the pumps inside a pressure increase, so that the pump can displace the offered amount of water for example to fill one or more Karbonatortöpfe. In part, the thus injected water with additions of preferably Co ² in feeding the water is also added at the same time and with this carbonated liquid is then served at least one dispensing nozzle to remove carbonated liquid or at least produce a post-mix beverage. Also, the carbonated liquid, which is in the Karbonatorkessel is used, for example, to supply a so-called Python with carbonated liquid. This usage is mostly applied to operation for post-mix. These are taps that have at least one inlet for carbonated liquid and at least one entrance for beverage syrups. These two liquids are mixed in the tapping process and so creates a preferred carbonated soft drink. Due to the high pressure that exists in the carbonator, which in turn resulted from the increase in pressure of the pump is used to feed with the specified pressure of the carbonator the preferred Python or taps to operate. This high pressure is also needed to, for example: 3 taps simultaneously. You could not, with for example: 3 bar domestic water connection. The same principle applies to a Karbonatorkreislaufsystem.

The invention now utilizes that by at least one pump, a carbonization is performed within the pump by giving on the input side of the pump for liquids, preferably Co ² and tap water. This is usually absorbed even by the pump itself. Thus, now Co ^{2 is} with water within the pump housing to use the pump to provide the required pressure to be carbonized for this type of delivery, at least one line cross-sectional constriction is applied at the liquid and liquid conduit exit point Pump. This liquid mixed with the applied principle with preferably Co ² now carbonized with a high pressure from the pump exits. Because the high pressure within the pump housing arises when the cross-section reduction was completed before the pump outlet, inevitably because the pump has to displace the offered liquid offset with preferably Co ² . At the same time, during this displacement, the preferential carbonation takes place, such as in the carbonator vessel. The carbonization within at least one pump housing has the advantage of carbonizing in the flow process, such as: an in-line carbonator. The advantage of the invention is that when using the invention, the above-mentioned Karbonatorsysteme saves completely because in pumps Karbonatorsysteme the pump needed so that it also carbonates at the same time and not only circulating fluids and is needed to increase the pressure. In Kreislaufkarbonatoren the invention has seen an even greater benefit on the material savings and energy consumption because Kreislaufkarbonatoren usually need at least two pumps for circulation operation and this are usually a booster pump to fill the Karbonatorkessel and operate the carbonation and at least one circulation pump order Keep fluid in circulation. Now you can thanks to the invention, the booster pump and the complete Karbonatorsystem omitted, so save. You only need the Kreislauφumpe, which is usually made of VA steel because you use the pump housing to carbonize and uses the same pump to keep the circuit for preferably carbonated liquids in the circuit. The preferred cross-sectional constriction of the conduit in which the preferred carbonated fluid is circulated is preferably applied prior to entry of liquids and gases to the pump since after cross-sectional constriction only the pressure provided by the water supply to the pump is present. This uses the invention to provide the pump with liquids and gases, for example: to refill the withdrawn liquid during tapping, also the lower pressure between the liquid inlet on the pump and the cross-sectional constriction after the outlet on the pump is used to normal Domestic water pressure liquids and gases can flow into the pump and can get back into the circulation under pressure increase within the pump housing and thus with freshly carbonated liquid in the same amount as before has been tapped or the tapping and refilling is the same time and the same amount. Only then can a trouble-free dispensing operation be guaranteed. This is the only way to ensure that the pump or pumps do not run dry and are therefore damaged. The cross-sectional constriction can also be introduced directly on the pump housing.

The following is a detailed description of the invention and the figure: 1 description

The pump (1) preferably VA steel pump housing, should preferably be operated via at least one electric motor. (Not shown pictorially) At least one main liquid supply for the pump (1) is to be attached to the pump connection (3) (not shown) and at least one oasis supply preferably main supply. (Not shown pictorially) Preferably, tap water and gases, preferably Co ^2, enter the liquid via the connection (3), the liquid and the gas can pass inside the pump housing (8). Then by the preferably electric motor connected. (Not shown in the picture) The movable part of the pump (J) within the pump housing (8) displaces the liquid, preferably conveying Co ² under pressure increase via the pump outlet (4) into the line (5). The necessary increase in pressure is achieved, for example, by the cross-sectional constriction (6) in order to initiate the carbonation required by increasing the pressure within the pump housing (8) in order to remove carbonated liquid at least via a tapping point. (Not pictured)

In this process can be carbonized via the pump (1) in the flow process. The carbonated water is up to the dispensing operation in the line (5) or is held during operation of the pump (1) in circulation and only in the dispensing new preferably tap water and preferably co ² flow over the connection (3) of the pump ( 1) and can be carbonized in the pump housing (8). This ensures that during the tapping process a pressure drop in the line (5) and the pump (1) takes place, that via the pump connection (3) and before the cross-sectional constriction (6) allows flowing of liquid and gases is still supported by the pump (1) is preferably a self-priming pump (not shown in the drawing) Between the pump connection (3) and the 4-point cross-sectional constriction (6), there is always only the pressure which predetermines the main liquid supply. (Not shown) This is necessary to allow it to be used without increasing at least one additional booster pump to assist the main water pressure before feeding the pump (1). (Not shown) Before the liquid feed to the pump (1) there will be a possibility to clean the pump (1) and all lines and taps and to feed the detergent. (Not pictured) The pump (1) has at least one bypass and pressure adjustment option, as well as at least one overflow valve inside or outside the pump (1) or pump housing (8). (Not pictured) FIG. 2 shows a schematically represented housing (1) made of preferably VA steel with at least one inlet possibility (4) for allowing tap water and Co ² to flow into the housing (8) or into the housing by the suction force of the pump (1) Pull housing (8).

By way of example, the component (16), the line (5) or the T-piece (5) is attached. On the component (5) a cross-sectional constriction (6) is attached, which makes it possible with cycle carbonators (SO) to ensure that the dispensing process via preferably post-mix Hahne, (34) not too much carbonated liquid through the Kreislauφumpe ( 1) is pushed past the taps (34) during the tapping operation in order to guarantee the greatest possible volume flow, the taps (34). This is secured via the lines (7X9) and the cross-sectional constriction (6) completed. The connection possibility (11) serves to connect the component (5) and inline carbonator (12) or the device (12) which preferably maintains tap water with Co ² before entering the pump (1)

The component (13) ensures that preferably tap water and Co ² via the possibility (14) (15) in the direction of inline carbonator (12) or mixer (12) preferably, filled with bulk material can flow and through the device (11) and the conduit (5) and the Eintrittsmδglichkeit (4) in the pump housing (8) passes to the preferred to carbonize tap water and Co ² by the pump inevitably builds up a high pressure on the cross-sectional constriction (6) on the outlet side for preferred carbonated liquids and then used to, for example: make soft drinks and via the lines (7) (5X1O) to the post-mix taps (34) to flow.

The outlet (3) for carbonated liquids can also be used for feeding, in this case, the entry possibility (4) is used to exit possibility for carbonated liquid.

The component (2) (not pictorially shown) can be used as overflow or relieving spill valve to an additional adjustment of the Baipasses or preferably used for pressure adjustment of the pump (1). Figure: 3

shows: a schematic diaphragm electric pump (17) which can also be driven by gases. (Not pictured) The can also consist of the housing structure (17) made of plastic. (Not pictured)

The pump (17) has at least one liquid and gas inlet and outlet (21) and at least one liquid and gas outlet and inlet (18) and at least one chamber (20) which is used for carbonization and a pressure or Baipass setting (19) for preferred: tap water and Co ² .

Figure: 4

shows: a schematic sketch of a pump (17) with the VersorgungsmögUchkeit about at least one inline premixer (12) dosed the inlet possibility (21) towards the pump inner housing (20) with preferably tap water and CcP to ensure it in that thereafter a continuous carbonization takes place within the pump housing (20)

Since this is ensured, the line (15) and the line (14) are suitable to supply the component (13) with preferably tap water and Co ² , thus the liquid and the gas can get into the inline premixer (12) and via the device (11) and (30) through the opening (21) in the pump interior (19) pressure increased by the cross-sectional constriction (6) which causes the pump (1) (17) to increase the pressure for a good carbonization is required to force, because the pump, (1) (17) the liquid and the gas, through the cross-sectional constriction (6), presses. By such a preferred measure, an increase in pressure is made possible and the thus carbonated water can pass through the opening (18) on the pump (1) (17) in the line (5), through the interior of the line (10). Figure: 5

1 shows a schematic sketch of a pump housing (I) ₇ that an additional feed possibility (24) to gases or liquids or both together in addition to the entry possibilities (4) (3) for gases and liquids at or within the pump (1) in the direction Pump interior (8) with the Baipass option (2).

Figure: 6

shows: a schematic sketch of a pump housing (1) that has already been made at the factory with a bottleneck, preferably cross-sectional constriction (3) intended to ensure on the outlet possibility (3) the required high pressure in the pump (8) , This is ensured inside the pump housing (8) by previously known techniques such as: displacement mechanisms (not pictured)

6 shows an additional Baυteil (31) with a bore (25) which serves for cross-sectional constriction, which can be subsequently used in any conventional, preferably positive displacement pump (1) and roasted with the component (31), serving for Druckerhδhung.

FIG: 7

shows a schematic sketch of a Pumpengehauses (1) that at least one inline pre-mixer (12) inserted into the entry possibilities (3) (4) of the pump housing (1) in the direction of the pump chamber (8). This in-line premixer (12) or in-line carbontor (12) is equipped with at least one device (32) which has the possibility of passing gases via the opening (28) and the opening (53) in the direction of inline (12) to ensure. This method and structurally arranged can serve to use the pump (1) as a shock-carbonator pump (1), but also as a carbonator pump (1), inside the pump housing (8) with the components required for this, ( Figuratively not shown) carbonated and used at the same time as a circulation pump (1) if not tapped, because then no new pre-impregnated liquid can get into the pump interior. (Not pictured)

For example, Co ² in the direction of the inline premixer (12) is released via the opening (28), and tap water of the line (27) is preferably released via the opening (26) in the direction of the inline premixer (12). As a result, the withdrawn amount withdrawn during the tapping can flow back towards the pump and the pump (1) carbonated liquid can be used for tapping and there is no gap of carbonated liquid in the lines (49X40) (6) (5) and preferably pumps - inner housings (8) and (20) and, as a result, there may also be no lack of liquid of carbonated liquid, such as: at the post-mix taps (34). (Not pictured)

The preferred bulk material (12) is preferably introduced into one or more hollow bodies (53) and is secured as a holder and securing of preferred sieve material (33). The hollow body (53), has at least 2 openings (33) on the inflow and outflow, ensures fjk uncarbonated liquid or carbonated liquid.

Figure: 8

1 shows a schematic sketch of a top-counter post-mix dispensing system (38) with intriguing carbonator system (12) (1) (17) and continuous cooling principle with still water precooling (42) which are also used as aftercooling (42) for still water may preferentially use the in-line pre-mixer (12) with preferentially cooled tap water for pre-carbonation and with at least one after-cooling line (40) for carbonated liquids, preferably tap water which may also be filtered (not shown pictorially) via line (44) in the preferential automatic pressure regulator (45), the doses over the existing fluid pressure, preferably the Co ² pressure depending on the existing fluid pressure, dosed to the or inline pre-carbonator (12) to get into the pump (1X17) or may flow in conjunction with preferably tap water flowing from the mains through the automatic pressure regulator (45) Zapf process, and the existing flow pressure via a piston control (pictorially not shown) within the automatic pressure regulator with a differential pressure adjusted to the flow pressure of the liquid is used so that no Co ² excess or too high Co ² pressure can arise over the liquid pressure. (Not pictured) This principle of mutual dependence is also used preventively against pressure fluctuations in the water network to always keep a constant dosage of the liquid flow and liquid pressure over the preferential Co ² pressure and flow needed for the carbonation and Hauptkarbonisierung the pump (I) (17). Otherwise it could happen that with increasing pressure of the liquid pressure and with unchanged set Co ² pressure, no carbonation is possible, because the previously increased fluid pressure prevents the Co ² from flowing towards the mine pre-carbonator (12) and pump 0X17) stream. Since the previously set Co ² pressure in this case is lower than the flow pressure, that would be the cause of a separate Co ² pressure regulator and separate liquid pressure regulator.

The combination of the automatic pressure regulator (4S) prevents these problems, this would also be advantageous if the liquid pressure was below the Co ² pressure, then the gas displaces the liquid flow, that even then no equally good carbonation can take place and the pumps ( I) (17) could be damaged (not pictured)

The regulated liquid flows through at least one check valve, backflow preventer (46) in the direction of pre-cooling line (42) preferably tap water can then flow in the in-line Vorkarbonator (12), in conjunction with Vorgeregeltem preferential Co ² gas via the line (47) in the Feed component (15) in the prechamber (13) of the inline premixer (12), this can only be done when tapping on the taps (35). At this moment, the liquid, in conjunction with gas, via the line (38), in the pump (1X17) and the chamber (8X20) and by the inevitable increase in pressure of the pump (1X17) passing through the cross-sectional constriction (6) caused and thereby a very good carbonization takes place inside the pump housing and is used in the flow method, because for example: in diaphragm pumps, the Verdränger- principle is applied, the narrower the space to the exit side (3) or (18) than a resistance to the liquid is required, the pressure is automatically increased by the pump (I) (17), which is needed for carbonization After the cross-sectional constriction (6) With the pressure again, partly down to the inlet pressure in front of the pump inlet (4X21 ) optionally in conjunction with the existing Co ² Druek (not shown pictorially). After passing through the carbonized liquid of the cross-sectional constriction, the carbonated liquid enters the Nachkühl- line (40) and can be tapped via the line (39) to the Zapmahnen (35). Figure: 9

shows: a schematic sketch of a circulatory carbonator principle, for preferential post-mix tap supply (34) with carbonated liquid via at least one tap water pressure regulator (44) may preferentially city water in the automatic pressure regulator for liquids and gases to flow, at the same time can preferably ² Co which is stored in a Vorratsbehalter is (not shown pictorially) in the automatic pressure regulator (45) and flow out. Both media flow simultaneously via the lines (47) and (41) into the feed component (13) for the inline Voπnischer (12). The premixed media are sucked by the pump (8) with the aid of the pump (8) and the admission pressure of the two media, and are raised very high in the pump housing (8) and can be pumped via the outlet (3) of the pump (1) The circulation circuit flow in and replace the previously removed amount of liquid, so that no Zapf interruption can take place.

In non-dispensing operation, the pump (1) serves to circulate the carbonated liquid in the circuit (49) and always cool through the refrigeration circuit (40) of which supply lines (48) go off to supply the valves (34) with carbonated liquid.
