Definitions
- the invention relates to a dissolving apparatus with a nozzle device for dissolving a solid in a solvent, preferably a powder Solid in water, according to the preamble of claim 1.
- Solid in powdered form such as citric acid or Sweeteners
- aqueous solution to keep them in this state in the To be further processed as part of the manufacturing process of the respective drink.
- Solvent the water, to suspend.
- JP 8-126826 A also shows a similar dissolving device, where the circuit flow is drawn off in the upper container side wall and the supply takes place as a vortex on the lower outer container edge and centrally from below as a horizontal annular gap flow.
- a mixing container for liquids is also known from US Pat. No. 5,564,825 , in which the circulation flow is removed from the mixing container at a central point in the lower container bottom and, at a distance from the longitudinal axis of the container, is fed to the mixing container via a nozzle.
- This nozzle combines an annular gap flow transversely to the longitudinal axis of the mixing container with purely axially ejecting hole nozzles.
- a nozzle device which, starting from a supply pipe and seen in the direction of flow, in an annular gap nozzle and a tubular nozzle branched.
- the annular gap nozzle generates an annular gap flow which in the is oriented substantially transversely to the longitudinal axis of the mixing tank.
- the remaining one Partial flow of the supplied suspension is applied via a tubular nozzle generates a motive flow in the mixing tank which, based on the longitudinal axis of the Mixing tanks, one axial to the head part and also a tangential one Directional component has.
- a convection flow is created via the tubular nozzle generated in the mixing tank, which records the entire tank content there and this circulates in both vertical and tangential directions.
- the one over the ring The other partial flow of the suspension, which is discharged from the slit nozzle, preferably crosses downward convection flow and thereby leads to a intensive mixing of the suspension and on the other hand favors it very high energy cross flow the suspension conditions. Since both the Removal of the suspension and its supply via the bottom part of the Mixing tanks take place, the convection flow and the annular gap flow cross inevitably. Through the convection flow, the entire Tank contents included in the mixing and dissolving process as planned; stagnant areas in the tank with less favorable mass exchange conditions are reliably avoided.
- annular gap nozzle it has proven to be advantageous to design the annular gap nozzle in such a way that it extends over an application angle of almost 360 degrees, measured in a plane perpendicular to the longitudinal axis of the mixing tank .. Through this measure, the annular gap flow over the entire Cross-sectional area of the mixing tank is discharged and can thus with the down over the entire circumference of the cylindrical jacket of the mixing tank cross the flowing convection flow.
- the proposed opening apparatus with a nozzle device is simplified advantageously if, as is further proposed, the feed pipe the nozzle device by removing the suspension from the Bottom part serving drain housing is passed. in this case is only a single opening in the bottom of the mixing tank is required.
- the feed pipe becomes coaxial arranged to the longitudinal axis of the mixing tank in the bottom part, then simplified on the one hand the arrangement in addition, on the other hand result largely from the Axially symmetrical expression of the flow pattern in the mixing tank in particular favorable dissolution and suspension conditions.
- the opening apparatus with a nozzle device ( FIG. 1 ) essentially consists of a mixing tank 1, with a bottom part 1a, a cylindrical jacket part 1b and a head part 1c, a housing 2 flanged to the bottom part 1a, which consists of an outlet housing 2b and an inlet housing arranged underneath 2a, and a circuit line 6 starting from the outlet housing 2b and opening into the inlet housing 2a.
- the latter consists of a suction line 6a, which connects the outlet housing 2b to a circulation pump 5, and a pressure line 6b, which leads from the circulation pump 5 to the inlet housing 2a.
- a feed device 4 for a solid F opens into the suction line 6a.
- a nozzle device 3 penetrates the outlet housing 2b in order to engage in the bottom region of the mixing tank 1 via a bottom opening 1d in the bottom part 1a.
- the nozzle device 3 consists of a feed pipe 3a (see also FIG. 2 ), which starts from a partition wall, not specified, arranged between the inlet housing 2a and the outlet housing 2b and is delimited at its other end by a cover 3b such that between the end of the Inlet pipe 3a and the cover 3b, an annular gap nozzle 3c is formed.
- the cover 3b is connected to the feed pipe 3a via at least one connecting web 3e, and it is also provided with a preferably centrally arranged, not designated opening to which a pipe nozzle 3d is connected.
- FIG. 2 shows a vertical angle of attack ⁇ of the tubular nozzle 3d for generating the axial direction component, the tangential directional component results from a tangential angle of attack ⁇ ( FIG. 2a ).
- the mixing tank 1 contains the quantity to be dissolved Solid F necessary amount of solvent, usually water, submitted. Then the water is circulated via the circulation line 6 by means of the circulation pump 5 from the bottom area of the mixing tank 1 and the subsequent drain housing 2b suctioned off and then the mixing tank 1 via the inlet housing 2a and the connecting pipe 3a following this on the way over the Annular gap nozzle 3c and the tubular nozzle 3d fed again.
- the driving flow T generates a convection flow K in the mixing tank 1, which is oriented upwards on the one hand and tangentially on the other, ie in the direction of the circumference of the mixing tank 1 and which leads to a substantially downward flow in the region of the cylindrical jacket part 1b.
- the latter is crossed in the bottom region of the mixing tank 1 by an annular gap flow R generated in the annular gap nozzle 3c. Due to these intersecting currents, there is an intensive suspension and mixing movement.
