Definitions
- the invention relates to a method and a dispersing device for design a powder cloud that emerges when a powder / air mixture emerges from a Powder spraying device is created.
- the dispersing device is particularly suitable for spray devices in which a Powder / air mixture exits a fluidization chamber through a nozzle; it is but also applicable in other systems, such as a spray device, in the case of the dispersing device, a powder / air mixture via a hose is fed.
- EP A1 0574 305 describes a dispersing system with a rapidly rotating one Disc proposed, using speeds above 3000 rpm. Such However, systems are mechanically sensitive and have been used in powder sprayers only a limited service life.
- the object of the invention is a method and a Specify dispersing device with which, in addition to a design possibility of Spray cloud also improved charging can be achieved.
- This task is carried out in a method for forming a powder cloud according to the Preamble of claim 1 by introducing the control air at several points solved within the spray device.
- a dispersing device having specified features solved.
- a hollow body becomes flows through a powder / air mixture.
- the hollow body has in its wall Bores through which one or more streams of compressed air can be introduced tangentially.
- An alternative embodiment of a dispersing device is specified in claim 9.
- a powder / air stream flowing from a nozzle impinges the tip of a conical baffle and flows along the conical surface an outlet.
- the powder / air flow is passed through an annular gap, which through the cone jacket and a funnel-shaped guide wall spaced from it is formed.
- annular channel In the area of the inlet nozzle there is an annular channel with several holes arranged, through which in the tangential direction a controlling compressed air on the powder / air flow is conductive.
- this control air can also be drilled through holes in the funnel-shaped guide wall can be initiated.
- the powder spray cloud shape is not determined solely by the constructive design is, but still changeable during operation by changing the control air supply is. It can also be used with a flat nozzle. Powder deposits in the dispersing device are largely avoided. The one with the disperser achieved helical movement of the powder particles in the powder cloud leads the powder particles are very likely to be close to the high voltage electrodes over and thereby causes an improved electrostatic charge, which in turn leads to an improved deposition of powder on a workpiece.
- FIG. 1 shows a schematic representation of a section through a fluidization container 2, only a section of the container 2, which is closed per se, being shown.
- the container 2 In the container 2 there is fluidized powder 8, which can be removed from the fluid bed with the aid of a removal tube 25 and controlled by a closing device 13.
- the locking device 13 In the exemplary embodiment shown, the locking device 13 consists of a tube opening into the extraction tube 25, through which compressed air can be introduced, which in the closed state forces fluidized powder 8 back into the container 2.
- the fluidized powder 8 passes through a nozzle 11 as a powder / air stream 16 into a dispersing device 1 a.
- the dispersing device 1 is designed as a cavity 3, the through a tube 4, the nozzle 11 as an inlet for the fluidized powder 8 and through a Outlet 12 is formed.
- the cavity 3 can also have a different geometry, e.g. B. instead of a tube 4, a cone can also be used, the nozzle 11 is arranged at the beginning of the cone with the smaller diameter.
- a plurality of holes 5 are made in a row over the circumference of the tube are distributed; it is also possible to use several such rows with holes 5 in succession in the axial direction, d. H. in the spray direction. From the sectional view A-A, the design of the holes 5 can be seen more clearly. You are executed that a compressed air introduced through the bores 5 into the cavity 3 as Control air 6 tangentially touches the powder / air stream 16. This forms one towards the outlet 12 increasing helical movement of the powder / air flow 16 out.
- the outlet 12 can be made funnel-shaped, whereby - supported by the centrifugal force of those in rotation Powder particles - an expanding powder cloud 15 forms.
- the dispersing device 1 is double-walled, whereby an outer chamber 7 is created, into which the control air 6 via a feed line 9 is supplied and from which the control air 6 into the cavity 3 through the bores 5 can be initiated.
- the powder particles are charged with the aid of high-voltage electrodes 14 outside the outlet area 12.
- the shape of the powder cloud 15 can be influenced not only during operation by the supply of control air, but also by the choice and optimization of the geometry of the dispersing device.
- Some essential parameters are given in Fig. 2 . These parameters are the length L 2 , measured from the - possibly first - inlet point 5 for control air 6 and the start of the outlet 12, the distance L 1 between the nozzle 11 and the inlet point 5, the diameter D1 of the tube 4, the diameter D2 the funnel-shaped expansion of the outlet 12, the opening angle ⁇ 1 of the funnel-shaped expansion, the opening diameter D 3 of the nozzle 11, the diameter D 4 of the bores 5 and the number of bores 5.
- Fluidized powder 8 is introduced into the dispersing device in the axial direction via a nozzle 11.
- the powder / air flow 16 generated by the nozzle 11 strikes the tip of a large conical baffle 17 just behind the nozzle 11.
- the powder / air flow 16 flows along the jacket of the conical baffle 17 to an outlet 12.
- the expanding powder / air flow 16 is guided through a guide wall 18 adapted to the cone shape.
- the guide wall 18 is part of a feed channel 19 into which control air 6 is introduced via a feed line 9, which flows out tangentially toward the powder / air stream 16 via bores 5, which are shown in the sectional drawing by a sectional plane AA.
- control air 6 also via an annular channel 20 in the axial direction, but also tangential to the Powder / air stream 16 are passed.
- the ring channel 20 is for this purpose via a second supply line 21 control air 6 is supplied, which exits through holes 22.
- the one from the Ring channel 20 through the bores 22 tangential to the powder / air stream 16 Control air 6 accelerates the powder / air flow 16 on the one hand in the axial direction and also sets it in a rotating motion.
- In the outlet area 12 are high voltage electrodes 14 arranged.
- the emerging from the slot-shaped outlet 12 Powder cloud 15 is particularly effective due to its helical movement charged.
- the shape of the powder cloud 15 can be determined by the two feed lines 9 and 21 supplied control air 6 are influenced.
- control air 6 is supplied only in such an amount as for formation the desired shape of the powder cloud 15 is required because the control air 6 Powder density reduced in an undesirable manner per se.
- the proposed dispersing device of the first and second variant or the one proposed at the same time Methods for influencing the shape of the emerging powder cloud are therefore Particularly suitable as a dispersing device for a spray device, which with a Powder / air mixture with a high powder content works, such as that in FIG. 1 indicated spraying device.
