Definitions

  • the invention relates to a device for spraying a liquid, according to the preamble of Claim 1.
  • a generic device for spraying a Liquid is known from FR-A-2 526 330.
  • the rotating surface is partly from a housing envelops and leaves an opening over a partial circumference. Instructs them to collect retained drops Reservoir and a flow path, in the course of which a Pump is provided to restore the liquid collected to combine with the inflowing liquid.
  • This pump that returns the collected liquid is the cone of a rotating body, which is also the comprises rotating surface, designed, the Cone tip into the one at the bottom of the housing Reservoir immersed.
  • the liquid is due to the Centrifugal force through the rotating cone surface conveyed above where they are at right angles to the axis of rotation is thrown out.
  • a greater inclination of the axis of rotation from the vertical is not possible because then the cone tip no longer in the Immersed liquid reservoir.
  • the object of the invention is a device of the beginning to create the type mentioned, even at highly inclined Axis of rotation up to the horizontal is suitable, which in Reservoir accumulated fluid again rotating Feed area.
  • opening is adjustable, can for example by changing the opening sector too the directed flow emerging from the opening desired spray width can be adjusted. Will the location of the Opening changed, for example sprayed upwards become.
  • a suction of collected liquid after the Spraying is facilitated by the fact that the device assigned a dosing pump for the supply of liquid is, the conveying direction is reversible. If they also have a line for feeding Has liquid that opens into the reservoir is arranged, then the intended one in this case Dosing pump by reversing the direction of rotation that too Take over suction.
  • FIG. 1 denotes a rotating axis 2 Centrifugal disc, from the outer edge of which rotating Surface drops are thrown off.
  • the slinger is encased by housing 3.
  • About a part of the An opening 4 extends in the housing of the centrifugal disc.
  • the housing 3 consists essentially of nozzle body 5 and Cover 6.
  • Opening 4 can be adjusted by Segment aprons 9 and 10 (Fig. 3) can thus be changed. This can affect the spray width. Will the Opening by changing the cover 6, for example after laid above, can also go against the direction of the Gravity sprayed. It is important that that Reservoir 29 remains below.
  • Pump disk 30 is coaxial with centrifugal disk 1 integrally formed and thereby with the drive shaft 12 Centrifugal disc firmly connected.
  • Drive shaft 12 is part a suitable motor 14.
  • a feed opening 16 is provided through which Liquid to be sprayed into the nozzle body 5 and Cover 6 formed housing 3 is passed.
  • pump disc 30 runs in the direction of arrow 19 (FIG. 3) around.
  • FIG 2 is a view of the inside of the Nozzle body 5 with nozzle feeding according to arrow direction II in Figure 1 shown. The same parts are as in the rest Figures with the same reference numbers. Bridges 23, 24 inside the nozzle body 5 serve to guide the Liquid.
  • the liquid flowing through opening 16 is in Direction of the flow path 27 in the center of the nozzle body 5 arranged beak-shaped semi-open Channel 13 passed, which is integrally formed on the webs 24. Of the groove 13, the liquid is then the inside of the Abandoned disc 1.
  • FIG. 4 shows schematically the operation of the Contraption.
  • a container B is turned into a dosing pump P1 a volume flow V1 is sucked in from line L1 and the Centrifugal disc 1 supplied. From there becomes a sub-volume V4 the droplets formed are thrown off. The rest will be in Housing 3 retained and collected in the reservoir 29.
  • the centrifugal disc 1 is driven by a motor 14 via drive axle 12.
  • the reservoir 29 becomes the Volume flow V3 promoted by means of pump disc 30 and with the supplied volume flow V1 combined, and together again abandoned the centrifugal wheel 1.
  • Flow path 26, 28 is also the alternative, in broken line, line L3 possible, however, as described, a different behavior due to the device.
  • FIG. 5 shows an exploded view of the Contraption.
  • the same parts are the same in it Provide reference numbers.
  • the one in dash-dotted lines Axis 2 shown here gives the coaxial Allocation of the individual parts.
  • the nozzle body 5 is accordingly on a mounting plate 31 assembled.
  • motor 14 after plugging in Cover 6 and slip on the motor housing 34 to one another assembly group put together.
  • Shaft 12 of the engine 14 is then attached to the centrifugal disc 1 by means of clutch 32 attached.
