Definitions
- a liquid jet is required that strikes the wall with the highest possible jet power. All parts of the wall must be reached with the jet in order to achieve the desired cleaning effect.
- a rotating nozzle which naturally guides the jet over the entire inner peripheral surface of the container.
- the cleaning fluid which flows through the nozzle is expediently used to drive the rotating nozzle.
- Another requirement placed on such a nozzle for cleaning containers is a speed which is approximately independent of the pressure of the liquid, even when using foam.
- the thrust bearing also acts as a friction brake, the braking effect of which is controlled by the fluid pressure.
- the axial gap between the two bearing surfaces of the axial bearing initially occurs due to the liquid flowing through the nozzle sets a fluid friction, which changes into a dry friction with increasing pressure.
- the proportionality between speed and liquid pressure ends above approx. 0.5 bar. Instead of this, the speed even begins to drop again beyond this pressure, the speed drop or the maximum speed being dependent on further design parameters of the new nozzle.
- the driving force does not come from the recoil of the liquid jet emerging from the nozzle. Rather, this driving force is provided by the turbine and, depending on how strongly the exit angle of the liquid jet is inclined towards the normal on the exit surface, the jet can also provide an additional force in order to further compensate for braking effects at high speeds, if necessary.
- the rotating nozzle starts automatically when the coefficient of friction in the thrust bearing is in the range between 0.05 and 0.15.
- coefficients of friction can be achieved, for example, if one or both axial bearing surfaces contain PTFE or a material with comparable coefficients of friction.
- the turbine is advantageously preceded by an injector, through which an injector with a tangential direction jet flowing into the turbine is generated.
- the passage bore in the injector is laterally offset and also inclined with respect to the axis of rotation of the turbine.
- a very simple turbine is obtained if it has the shape of a cylindrical disk, in the outer peripheral surface of which grooves are machined as passages. So that in any case the new rotating nozzle starts up automatically and runs at a uniform angular velocity, the number of passage bores in the injector and the number of passages in the turbine are prime factors.
- the housing 2 is delimited by a union nut 9 screwed onto the external thread 3, which is provided coaxially with a liquid inlet 11.
- the liquid inlet 11 is a bore through the bottom of the union nut 9 with an internal thread 12.
- a turbine 13 rotates in the cylindrical interior 4, which has a constant cross-section up to the vicinity of the collar 8.
- This turbine 13 is a cylindrical disk, the outside diameter of which is slightly smaller than the inside diameter of the cylindrical interior 4, and the outside circumference of the embodiment shown contains a total of eight grooves 14 with a rectangular cross section.
- the grooves 14 penetrate the disk forming the turbine 13 from a front end face 15 to a rear end face 16, and the grooves 14 are also open in the radial direction.
- the figures show that the grooves 14 are inclined relative to the axis of the turbine 13, which coincides with the axis of symmetry of the turbine 13.
- the angle that the longitudinal axis of each groove 14 forms in the projection with the axis of rotation of the turbine 13 is between approximately 10 o and 40 o . In the embodiment shown, the angle is exactly 25 o .
- the disk forming the turbine 13 merges in one piece into a turbine shaft 17.
- the turbine shaft 17 has, directly adjacent to the turbine 13, a cylindrical section 18 with a larger diameter, which merges with an annular shoulder 19 into a cylindrical section 21 with a reduced diameter.
- the diameter of the section 21 is dimensioned such that it can rotate in the bore of the collar sleeve 7 with little play.
- the length of the section 21 is sufficient for the turbine shaft 17 to project outward from the housing 2 in order to be able to fasten a nozzle head 22 on its projecting end.
- both the collar sleeve 7 and the ring 25 with a rectangular cross section are made of PTFE or a comparable material.
- the outer diameter of the ring 25 is approximately 19 mm, while the inside diameter is approximately 13 mm corresponding to the outer diameter of the section 21 of the turbine shaft 17.
- the height of the ring 25 is approximately 1 mm.
- a further bearing is provided on the rear end face 16 by means of an integrally molded cylindrical pin 26 which is coaxial with the turbine shaft 17.
- This pin 26 rotates in a blind hole 27, which is contained in an insert body 28.
- the insert body 28 has the shape of a flat truncated cone and is seated in the rear end of the cylindrical interior facing the union nut 9 4. So that the insert body 28 cannot be advanced by the liquid pressure, its diameter is somewhat larger than the main section of the interior 4 located in the region of the turbine 13, which is cylindrical towards the rear end on a shoulder 29 which jumps radially inwards expanded.
- This insert body 28 contains a total of three obliquely running bores 31 which lie on a pitch circle diameter which is equal to the pitch circle diameter of the grooves 14 of the turbine 13.
- the bores 31 run at a more inclined angle than the grooves 14 with respect to the axis of rotation of the turbine 13 and in the exemplary embodiment shown, the angle which the axes of these three bores 31 form with respect to the axis of rotation is 55 ° .
- the diameter of the three bores 31, which are distributed equidistantly, is approximately 4 mm and is somewhat smaller than the width of the grooves 14, measured in the circumferential direction.
- the insert body thus acts as an injector for a turbine 13.
- the liquid can flow via the liquid inlet 11 through a gap 32 between the insert body 28 and the bottom of the union nut 9 to the through bores 31.
- the liquid flows out of the interior 4 via transverse bores 33, which are made in the turbine shaft 17 in the section 18 with a larger diameter.
- transverse bores 33 open into a blind bore 34, which leads into the turbine shaft 17 from the end lying outside the housing 2.
- the nozzle head 22 consists of a pipe section 35 which is plugged onto the turbine shaft 17 and secured there by appropriate means and which forms a shoulder 36 and a ring 37 which is plugged up to the shoulder 36 onto the pipe section 35 and has a hexagonal cross section the pipe 35 passes through a coaxial bore 38 of the ring 37.
- the bore 38 is widened radially outward at 39 inside.
- a nut 40 is screwed onto the closed front end of the tube 35.
- a total of three relatively large bores 41 to the outside, namely the bores 41 are made such that they have no or only a small component in the circumferential direction.
- the operation of the rotating nozzle 1 described so far is as follows:
- the liquid to be sprayed is fed into the liquid inlet 11 under pressure. From here, the liquid flows through the gap 32 along the lateral surface of the insert body 28 to the three obliquely running bores 34, which generate a total of three liquid jets.
- This liquid jets have a component in the direction to the turbine 13 and also a component in the circumferential direction as the holes forming the passages 31, are inclined obliquely o under the mentioned angle of 55 against the axis of rotation.
- the liquid flowing out of the passages 31 strikes with a peripheral component against the walls of the grooves 14 lying in the flow direction, as a result of which the turbine 13 is set in rotation.
- the liquid flowing through the grooves 14 enters the Area of the interior 4 between the turbine 13 and the axial bearing 23. Depending on the pressure conditions, a very small part of the liquid gets into the gap of the axial bearing 23 and causes liquid lubrication there. The vast majority of the liquid, however, flows through the radial bores 33 into the bore 34 and from there into the tube 35, which it leaves through the transverse bores 32 in the direction of the nozzle outlets 41. Since the turbine shaft 17 is connected in one piece and thus also in a rotationally fixed manner to the turbine 13 and the nozzle head 22 is held in a rotationally fixed manner on the pipe 35, it rotates with the turbine 13.
- the speed at which the turbine 13 rotates depends on which angle the grooves 14 form with the axis of rotation of the turbine shaft 17 and which angle the through bores 31 also form with the axis of rotation of the turbine shaft 17. Furthermore, the speed is influenced by the distance that the end face 16 of the turbine is from the opposite plane side of the insert body 28. The larger this gap, the lower the speed.
- a favorable value for the gap width is approximately 1.6 mm, while the outer diameter of the disk forming the turbine 13 is approximately 32 mm and the thickness is approximately 8 mm.
- the cross-section of the outlets, that is to say the cross-section of the individual bores 41, is approximately 3 mm 2 in each case and represents the essential flow-limiting resistance. It is assumed that all other flow resistances are smaller than the flow resistance caused by the outlets 41.
- the speed of the nozzle head 22 increases proportionally with the pressure up to approximately 37 rpm up to approximately 0.5 bar. If this pressure is exceeded, i.e. in the range between approx. 0.5 bar and 1 bar, the speed characteristic curve tilts and a further increase in pressure initially leads to a reduction in the speed, insofar as the speed up to a range of approx. 10 bar of the nozzle head 22 drops to approx. 30 rpm. Only when the pressure increases further does the speed gradually increase again.
- the new nozzle 1 is a slow-running nozzle and there is no pressure-proportional change in speed in a significant range of its operating pressure, namely between 0.5 bar and 15 bar.
