Definitions
- the invention relates to an electrostatic rotary atomizer, the electrostatic charge of the coating agent to be applied works and has an atomizer head which is driven on a rotating Shaft is arranged and a nozzle for the coating agent includes.
- the coating agent which is color or Lacquer and the like is inside a driven hollow shaft fed to a stationary nozzle.
- the coating agent comes from the nozzle on the fast rotating, usually bell-shaped atomizer head and is finally released from its atomizer edge.
- These features are shown in German utility model 92 17 458 and described. So that flung radially away from the atomizer edge Paint particles must get onto a workpiece to be painted the atomized paint can be moved forward in the axial direction.
- a steering air flow is usually used. It emerges from one Wreath of holes behind the rotating bell atomizer and then acts on the atomized paint particles in the axial direction.
- the spray patterns have a diameter of around 500 up to 700 mm. Radial centrifugal forces, also radial, from the rotating atomizer initiated air flows and axially acting steering air flows overlap in such a painting process.
- the said lead in particular when atomizing metallic paints Framework conditions for a significantly different training of the achieved Metallic effect than when applying metallic varnish with a conventional, air atomizing spray gun.
- the invention has for its object to provide a rotary atomizer to create an atomizer head with the help of which it is possible to create spray patterns with the smallest possible diameter while still having a large amount of paint to generate per unit of time and with comparable atomization quality as in the case of a larger diameter rotary atomizer.
- the invention provides that the atomizer head on its periphery several axially spaced Outlet openings with atomizing edges for the coating agent having.
- the invention has the result that one for generating a small spray pattern suitable atomizer head despite its small diameter is able to atomize the same amount of paint as before well-known atomizer head with a large diameter. It is essential that Outlet openings with atomizer edges in sufficient numbers at the atomizer head are provided, these outlet openings expediently several atomizer edges arranged one behind the other in the axial direction form.
- the achievable with such an atomizer head Spray pattern has the desired, small diameter and is nevertheless able to process a large amount of paint per unit of time.
- metallic effect when processing metallic paints an appearance like when using an air atomizing Spray gun. Also penetration of the atomized and electrostatic charged varnish in forms with the effect of a Faraday Cages can be realized better.
- a rotary atomizer 1 according to FIG. 1 comprises an atomizer head 2, that in a housing 3 in a generally known manner on a shaft 4 is stored.
- the shaft 4 is a hollow shaft.
- Located inside there is a feed pipe 5 with holes 6 and 7 for paint or detergent.
- the holes 6 and 7 lead to a nozzle 8 at the free end of the Feed pipe 5.
- FIG. 2 is also during the Painting process stationary nozzle 2 inside 9 of the atomizer head 2nd
- the drive for the hollow shaft 5 and the supply of the holes 6 and 7 in the feed tube 5 do not differ from known rotary atomizers.
- the nozzle 8 also serves to guide and dispense the liquid Coating agent or a cleaning agent in principle known way. However, it is useful if the nozzle 8 or their Openings are designed so that there is not a cylindrical spray results, but a fan-shaped beam or a beam in the form of a cone.
- the atomizer head 2 comprises an outside according to the exemplary embodiment cylindrical holding and carrying element 10, which at the same time for attachment serves at the free end 11 of the shaft.
- the nozzle 8 is then approximately in the middle of the atomizer head 2.
- a multi-part Atomizer element 12 arranged according to a first embodiment.
- the atomizer head 2 has several in the area of the atomizer element 12 arranged circumferentially and at an axial distance from one another Outlet openings 13 for the coating agent or for a cleaning agent on. Each of the outlet openings 13 extends over the entire circumference of the atomizer element 12 or the atomizer head 2. According to the exemplary embodiment, there are nine on the atomizer head 2 annular outlet openings 13 are provided.
- Each outlet opening 13 includes two circumferentially extending, circular atomizer edges 14.
- the atomizer head 2 has twice the number of atomizer edges 14 at an axial distance from each other.
- a plurality of disks 17 are used to form the atomizer edges 14
- the disks 17 are ring-shaped.
- the outside diameter all disks 17 are the same according to the embodiment.
- bores 18 in the disks 17 are from disk to Disc graduated in such a way that a disc 19 adjacent to the nozzle 8 a hole with the largest diameter and a cover plate 20th or a disk 21 closest to it has the smallest bore diameter have.
- the cover plate 20 has a centrally arranged according to the embodiment Exit opening 20 '.
- This outlet opening 20 ' has one Shape and shape similar to a Laval nozzle. Part of the nozzle 8 liquid supplied to the atomizing element 12 emerges from the central one Exit opening 20 'and passes through the centrifugal force over the exposed End face 20 '' to atomizer edge 14 '
- All disks 17 and, according to the exemplary embodiment, also the end disk 20 have an annular elevation on their side facing the nozzle 8 or an annular collar 22.
- the outside diameter of a each annular collar 22 is less than the outside diameter the disc 17.
- the inner diameter of the collar 22 is larger than that Diameter of the holes 18 in the disks 17. In the assembled Condition are thus slot-shaped grooves 23 on the circumference of the atomizer element 12 and form the outlet openings 13 with the Atomizer edges 14 ..
- each atomizer edge 14 16 Many radially directed supply channels lead to each atomizer edge 14 16. They have a triangular one in the area of each federal 22 Cross-section on how this is mainly from the illustration in Fig. 2 in the area the central axis 24 emerges.
- the area of each federal government 22 Feed channels 16 which are triangular in cross section are in the region of the radially outside lying, annular feed surfaces 15 only notches or grooves shallow depth.
- the outer, annular feed surfaces 15 are therefore according to the embodiment shown in Figures 2, 5 and 6 knurled.
- the notches belonging to the feed channels 16 run radially on the inside 16 'on the respective end face of the disks 17 and 20 on the nozzle side before reaching the holes 18 gradually.
- the disks 17 including those arranged on the end face End plate 20 serve fastening means 25, for example, in shape of screws. They pass through holes 26. These holes 26 are expediently in each case in the region of the collar 22 of the disks 17th
- Fastening the disks 17 to one another or to the holding and supporting element 10 is also due to other fastening techniques such as gluing, Clamps etc. possible.
- the holding and carrying element 10 is sleeve or ring-shaped. It is cylindrical on the outside according to FIG. 2 and deposited several times inside, so that it is on the free end 11 of the Shaft 4 is attachable.
- the variety of available atomizer edges 14 or their total length according to the number of disks 17 enables even with a small diameter of the disks 17 high quality processing of large amounts of paint per unit of time.
- Fig. 3 is a section along the line III - III in Fig. 2, but of one modified atomizer head 2a shown. Basically the same parts have the same reference numbers and the index a.
- the atomizer head 2a differs from the atomizer head 2 only characterized in that the annular, radially outer feed surface 15a between the collar 22a and the atomizer edge 14a of each disc 17a is not knurled. It is a smooth ring surface.
- Fig. 4 relates to a modified disc 17b, which instead of a smooth feed surface 15a is close to the atomizer edge 14b has dotted feed surface 15b.
- FIGS. 7 and 8 Further modifications of the discs shown in Figures 2 and 6 17 emerge from FIGS. 7 and 8. So the disc 17c is on the nozzle side provided with an annular cutting edge 27c delimiting the bore 18c. The ring cutter 27c radially guides the impinging liquid flow outward onto the adjacent ring surface 28c. Comparable ring areas 28c (FIG. 3) have all disks.
- a disk 17c can also face one the disc plane 30c angled, the atomizer edge 14c have supporting outer edge 31c.
- the frustoconical, angled Outer edge 31c directs the radially outward flowing liquid around, reducing their radial acceleration and accelerating tangentially becomes.
- the feed surface 15c can be smooth or knurled according to FIG. 7 his.
- Fig. 8 shows a detail of another disk 17d, which is complete or partially domed. Its feed surface 15d can also be smooth or in accordance with Fig. 8 knurled and for this purpose grooves 32d like the other knurled Have washers.
- the nozzle 8 at the free end of the feed tube 5 creates a conical Liquid flow or a liquid flow in a fan-shaped Shape. This is shown in Fig. 9.
