Definitions
- the present invention relates to a device for pumping a liquid in a liquid line, in particular in a bottling plant.
- Pumping devices for pumping a liquid within a fluid line can be designed, for example, as piston pumps, diaphragm pumps, progressing cavity pumps or peristaltic pumps.
- Such an application is e.g. the filling of liquids in containers, e.g. in the beverage industry.
- a bottle to be filled with a well-defined volume of a drink This can be ensured in different ways, for example by measuring a volume flow or by measuring the filling level.
- a reliable method which can be used in particular in volumetric filling, is the use of a piston pump, in which a piston in a cylinder executes strokes and displaces a defined volume of fluid with each stroke.
- a defined volume can be conveyed through a feed line from a storage container into the piston.
- the supply line is then shut off by a shut-off valve, which can also be designed as a check valve, so that no liquid can flow back into the reservoir.
- the liquid within the cylinder is then displaced by a piston stroke in the opposite direction from the cylinder and fed through a conduit to the container to be filled.
- this can be done under different pressures.
- both an already formed container can be filled and a preform can be simultaneously shaped and filled under high pressure.
- the problem with the use of such piston pumps is the cleaning. Strict hygiene regulations must be adhered to, especially for bottling plants for bottling beverages. This includes regular cleaning and disinfection, but this should be done as quickly as possible to avoid downtime of the affected machine.
- the intervention in a machine such as the disassembly of parts to be cleaned and disinfected, should be largely avoided in order to prevent the contamination of a machine by externally registered germs.
- the contents leading areas of a machine should be isolated as possible from the environment and can be cleaned without opening.
- CIP cleaning in place
- a device for pumping a liquid in a liquid line, in particular within a bottling plant, comprising a pump element and two valves arranged in the liquid line upstream and downstream of the pump element, the pump element having a pump piston running in a cylinder.
- the device according to the invention is characterized in that the pump element via a closed chamber with a constant volume has a secondary fluid on which the pump piston acts. Furthermore, the chamber is connected by an elastic, liquid-impermeable element with the liquid line in communication, which can deform under the pressure of the pump piston displaced volume of the secondary fluid.
- the device according to the invention can be pumped by movement of the piston liquid, which is located in the liquid line.
- the volume delivered per working cycle is determined by the stroke of the piston and the diameter of the cylinder. Because the piston operates only in the secondary fluid and does not come into contact with the pumped fluid, the pump device can be used for applications in which the fluid-carrying areas must be cleaned regularly.
- the piston pump does not have to be disassembled for cleaning. Cleaning-in-place procedures can be applied.
- the device according to the invention combines the advantage of simple cleaning of e.g. Diaphragm pumps with the advantage of easily determined delivery volume of piston pumps.
- an elastic element in particular a bellows or an elastic membrane can be used. It is also possible to use a rolling diaphragm or a rolling bellows.
- One or both valves in the fluid line may be check valves.
- FIG. 1 shows schematically an embodiment of a pump device according to the invention with a bellows
- FIGS. 2a and 2b schematically show a further embodiment of a pump device according to the invention with a membrane.
- FIG. 1 schematically shows an exemplary embodiment of a pumping device according to the invention.
- the device is used to pump a fluid located in a liquid line 1, as z. B. is used in a bottling plant.
- liquid contents to be conveyed from a reservoir not shown in the figure in the direction of the arrow V and in each case a defined volume in the direction of arrow B are introduced into a container also not shown here.
- the pumping device has a pump element 2, which is arranged on the liquid line 1 between two valves 3, 4, which are designed here as check valves.
- the valve 3 is located upstream of the pump element 2 and the valve 4 downstream of the pump element 2.
- the pump element 2 has a pump piston 6 running in a cylinder 5. Further, the pump element 2 has a sealed chamber 7 which contains a constant volume of water as secondary liquid contained in the chamber 7 is included. The pump piston 6 acts on the trapped volume of water.
- the chamber 7 also has an elastic, liquid-impermeable bellows 8a, which is in communication with the liquid line 1.
- FIG. 2 a shows a further exemplary embodiment of the pumping device according to the invention.
- FIG. 2b shows how the membrane 8b displaces liquid in the liquid line 1 when the piston 6 displaces the secondary liquid in the chamber 7.
- the displaced in the liquid line 1, hatched volume shown corresponds exactly to the displaced by the piston 6 volume, which is also shown hatched.
- the device combines the advantages of piston pumps with the advantages of diaphragm pumps.
