Definitions
- the invention relates to a swirl body, in particular for use in a conical nozzle, such as a full cone nozzle or a hollow cone nozzle for rotating a fluid flowing through, with a cylindrical base portion defining a cylindrical outer surface, wherein at both front ends of the base portion respectively a conically tapered and a conical end surface defining end portion connects, and wherein in the cylindrical outer surface of the swirl body a plurality of obliquely to a central axis of the swirl corpus extending swirl channels of the same geometry are formed with uniform displacement along the circumference of the swirl body and each swirl channel opens into both conical faces.
- Swirl nozzles for atomizing liquids have long been used in many technical fields. For example, such nozzles are used for painting, irrigation and cleaning purposes.
- a swirl nozzle the liquid to be sprayed is first rotated within the nozzle.
- a first method is located within the swirl chamber of the nozzle housing a swirl nozzle, a swirl body, while a second method does not require such a swirl body and are instead provided tangential entries into the swirl chamber.
- the present invention relates to the first method in which the liquid to be sprayed through at least one swirl channel on the outer surface of a cylindrical swirl body flows obliquely to a central longitudinal axis of the swirl body, whereby a rotational flow is formed.
- the fluid set in rotation then exits the at least one swirl duct open at the end, into an outlet chamber and leaves the swirl nozzle from there via an outlet opening of the nozzle housing which is funnel-shaped in the flow direction.
- Such a swirl nozzle in which the liquid to be sprayed flows through the swirl body only through the swirl duct or passages formed in its outer surface, causes the liquid not to fill the complete nozzle outlet diameter.
- the two end faces of the cylindrical swirl body from DE 20 2015 001 520 U1 are designed as planar end faces on which liquid residues can collect after completion of a spraying process.
- the regions of the planar end faces on which liquid residues can collect are referred to as "dead surfaces” and the spaces which can be occupied by the liquid residues and are adjacent to the dead surfaces are referred to as "dead spaces”.
- dead surfaces the regions of the planar end faces on which liquid residues can collect
- dead spaces which can be occupied by the liquid residues and are adjacent to the dead surfaces.
- the liquid residues located on the dead areas or in the dead spaces can lead to corrosion of the nozzle components with their increasing residence time.
- the deposits of lime and / or other solid constituents on the dead surfaces can form when the water content evaporates, which can no longer be removed in the area of the dead areas or dead spaces due to lack of sufficient liquid flow and the swirl nozzle in the course of time clog the time.
- a conical nozzle with a swirl body of the type mentioned is known from DE 94 1 1 591 U1.
- the swirl body here has a cylindrical base portion, at the two end-side ends in each case a conical end portion connects.
- a plurality of swirl channels are formed, which extend along the cylindrical base portion into the conical end portions.
- the swirl body is arranged in a jacket tube, and an aperture is provided in this jacket tube upstream of the swirl body. This serves to create a vortex ring between the diaphragm and the swirler, which pulls the medium particles from the inside to the outside.
- the present invention has the object, a swirl body of the type mentioned in such a way that it can be dispensed with the use of an upstream panel in the installed state.
- This object is achieved in that exactly two swirl channels are formed in the cylindrical outer surface of the swirl body with 180 ° offset from each other and each open into the two end faces.
- the two swirl channels are identically formed and arranged and expediently have over their length a constant inclination with respect to the central axis of the cylindrical base section.
- the swirler is penetrated by a central center bore extending along its central axis.
- a central center bore extending along its central axis.
- Such a swirl body having a center central bore which is inserted into a conical nozzle allows the formation of a Vollkegelsprüh brieflys with a uniform liquid distribution downstream of an outlet opening of the conical nozzle.
- the central center hole ensures that not only edge areas, but also a central area of an outlet chamber of the conical nozzle is charged with liquid.
- the diameter of the central bore can be chosen so that it is in a preferred ratio to the dimensions of the at least one swirl channel.
- the central bore contributes to the most complete possible completion of remaining in the nozzle liquid residues after completion of a spraying process.
- a swirler is used to produce a full-cone spray pattern that does not have such a central center bore.
- the inclination of the swirl channels is chosen so that overlap the two open axial ends of each swirl passage in the circumferential direction and thus a lower end opening of a swirl passage is visible when looking axially through the upper end opening of the swirl passage.
- the angle of inclination of the swirl channels is preferably selected so that at least 50%, in particular at least 60% and preferably at least 70%, of the lower end opening of the swirl channel is visible when looking axially through the upper end opening of the swirl channel.
- a swirl body with swirl channels formed in this way is suitable for producing a full-cone spray pattern or spray, without a central center bore passing through the swirl body along its central longitudinal axis.
- the swirl body is formed as a solid body, which tapers conically at its ends.
- the tip angle of the end faces or the conical end portions in the invention is greater than 90 °, in particular greater than 100 ° and preferably greater than 1 15 ° and is in particular 1 18 °.
- the ratio between the diameter of the base section and the axial section the length of the swirl body is in the range from 0.6 to 1.5, in particular in the range from 0.7 to 1.3, and preferably in the range from 0.8 to 1.2.
- the diameter of a series of swirl bodies is 9 mm and 6 mm, the height being uniformly 7.5 mm in each case.
- the same swirl body can be used. It is only necessary to increase by at least 15 °, in particular 15 to 20 °, the angle which the swirl channels enclose with the central longitudinal axis in comparison to the swirl body which is designed to produce a full-cone spray pattern.
- the swirl channels have a cross-section, which at its radially inner end has a circular section-shaped or semicircular end section, that is to say an (approximately) semicircular end section. It does not matter that this end is exactly half round. Rather, it is essential that it can be produced by a cutter of predetermined diameter.
- the end portion may also cover a circular area portion of less than 180 °.
- a rectilinear cross-sectional section can adjoin a semicircular end section which covers a circular area of 180 ° radially on the outside, the length of the rectilinear cross-sectional section being a maximum of 30%, in particular not more than 20% and preferably not more than 10% of the radius of the semicircular end section ,
- the rectilinear cross-sectional portion should have a small length compared to the semicircular end portion.
- a special swirl body of this embodiment is characterized in that the diameter of the base body is 9 mm and the inclination of the swirl channels relative to the central axis is selected as a function of the total area of the swirl channels according to the following table:
- Another such swirl body is characterized in that the diameter of the base body is 6 mm and the inclination of the swirl channels relative to the central axis is selected as a function of the total area of the swirl channels according to the following table:

- the ratio of the sum of the cross-sectional areas of all swirl channels to the cross-sectional area of the outlet opening of a conical nozzle in which the swirl body according to the invention is used is preferably 1 ⁇ (0.2 to 0.3).
- each swirl duct has a depth measured in the radial direction of between 0.5 mm and 1.5 mm. In general, the optimum depth of the swirl channels depends in particular on the exact type and size of the respective conical nozzle. Conveniently, at least a portion of the swirl duct bounding surfaces is curved.
- At least one collecting groove can be formed in one or each conical end face of the swirl body, which runs starting from the free axial end region of the respective conically tapered end section in the direction of a swirl channel and opens into the latter.
- a collecting groove is advantageous because it supports the outflow of liquid in the direction of the end-side openings of the swirl channels and into them.
- the collecting groove can run in the direction of the swirl channel and open into it.
- the collecting groove spirals around the respective tapered end portion.
- the collecting groove runs along any other route in the direction of the swirl channel.
- a collecting groove in a swirl channel opens.
- the one collecting groove or the plurality of collecting grooves are preferably milled into the respective conical end face.
- a conical nozzle with a nozzle housing and a swirl body such as the swirl body described above.
