Definitions
- the invention relates to a plasma nozzle for the treatment of Surfaces, in particular for the pretreatment of Plastic surfaces, with a tubular, electric conductive housing, one of a working gas flowed through nozzle channel forms, and a High frequency generator for applying a voltage between the electrode and the housing.
- a plasma nozzle of this type is described in DE 195 32 412 A1 described and serves, for example, Pre-treat plastic surfaces so that applying of adhesives, inks and the like on the Plastic surface allows or easier.
- a such pretreatment is required because Plastic surfaces in the normal state not with Liquids are wettable and therefore the printing ink or do not accept the adhesive.
- the surface structure of the plastic is changed so that the surface for liquids with relatively large Surface tension is wetted. The surface tension the fluids with which the surface just barely is a measure of the quality of the Pretreatment.
- the plasma nozzle is a relatively cool, but highly reactive plasma jet reached, the about the shape and dimensions of a candle flame has and thus also the pretreatment of profile parts with relatively deep relief allowed. Because of the high Reactivity of the plasma jet is sufficient for a very short time Pre-treatment, so that the workpiece with correspondingly high Speed past the plasma jet are passed can. Due to the comparatively low temperature of the Plasma jet is therefore also the pretreatment of heat-sensitive plastics possible. There no Counter electrode on the back of the workpiece is required, the surfaces of any thick, block-like workpieces, hollow bodies and be easily pretreated. For one uniform treatment of larger surfaces is in the mentioned publication a battery of several offset plasma nozzles have been proposed. In However, this case is a relatively high apparatus Effort required.
- the object of the invention is therefore to a plasma nozzle which defies a very compact construction Larger surface treatment of workpiece surfaces allows.
- This task is characterized by a plasma nozzle of the type mentioned solved that the outlet of the nozzle channel as transverse to the longitudinal axis of the nozzle channel extending narrow slot is formed.
- the working gas in the nozzle channel be twisted.
- the twisted plasma jet can be with the help of the outlet slot fan-shaped. At most, the twisting leads to a minor S-shaped distortion of the fan when facing the mouth frontal the plasma nozzle looks.
- the intensity distribution of the plasma along the length of the slot can be, for example thereby controlling that the width of the slot varies over the length becomes.
- This arrangement is particularly simply connect when the mouth of the nozzle channel including the Slot and the cross channel through a separate mouthpiece of insulating Material (ceramic) or preferably made of metal is formed in the mouth of the housing is pressed or screwed.
- the transverse channel is open at both ends, and these open ends are surrounded only with a certain distance from the walls of the housing, so that a part of the plasma can escape at the ends of the transverse channel and then deflected by the housing walls obliquely in the direction of the workpiece becomes.
- the plasma compartment will then be particularly intense at both edges Boundary rays limited, which pull apart the fan formally. hereby can be the shape of the fan and the intensity distribution of the plasma jet within the fan, for example, adjust so that the downstream Edge of the plasma fan assumes a concave shape, so that the fan a Dovetail resembles.
- the outer jacket of the housing of the plasma nozzle on both sides the plane of the fan auxiliary air to be supplied.
- the outer surface of the housing of the plasma nozzle in the mouth region not conical, but is prism-shaped, so that two flat surfaces are formed, which converge to the plane of the fan.
- the plasma nozzle shown in the drawing has a tubular housing 10, the one elongated, conically tapered at the bottom nozzle channel 12 forms.
- the nozzle channel 12 is an electrically insulating ceramic tube 14 used.
- a working gas, such as air, is from the drawing fed into the upper end of the nozzle channel 12 and with the aid of an in the ceramic tube 14 used twisting device 16 so twisted that it is vortex-shaped flows through the nozzle channel 12, as in the drawing by a helical arrow is symbolized.
- a vortex core extending along the axis of the housing.
- a pin-shaped electrode 18 is mounted, which is coaxial projects into the nozzle channel 12 and to the by means of a high voltage generator 20 a high-frequency AC voltage is applied.
- High frequency generator 20 generated voltage is of the order of a few kilovolts and has, for example, a frequency of the order of 20 kHz.
- the metal housing 10 is grounded and serves as a counter electrode, such that an electrical discharge between the electrode 18 and the housing 10 can be caused.
- a corona discharge at the swirl device 16 and the electrode 18.
- This corona discharge is a Arc discharge from the electrode 18 to the housing 10 ignited.
- the arc 22 of this discharge is taken by the twisted inflowing working gas and channeled at the core of the vortex-shaped gas flow, so that the Arc then almost straight from the top of the electrode 18 along the Housing axis extends and only in the region of the mouth of the housing 10th branched radially on the housing wall.
- a cylindrical mouthpiece 24 made of copper used In the mouth of the housing 10 is a cylindrical mouthpiece 24 made of copper used, the axially inner end rests against a shoulder 26 of the housing.
- the conically tapered end of the nozzle channel 12 settles in the mouthpiece 24 continuous, with the same or slightly changed cone angle.
- the arc 22 branches within the mouthpiece 24 on the conical walls of the mouthpiece.
- the mouthpiece 24 has at the free, in Figure 1 lower end of a section 28th with a reduced diameter, with the peripheral wall of the housing 10th forms an open in the mouth direction annular channel 30.
- the conically tapered Tip of the nozzle channel 12 opens into a transverse channel 32 through a Cross hole is formed in the section 28 and at both ends to the Ring channel 30 is open towards.
- This transverse channel 32 according to Figure 2 a has circular cross-section, closes axially a narrower, diametrically through the mouthpiece extending slot 34 which, to the end face of the mouthpiece is open.
- the swirling through the nozzle channel 12 flowing working gas comes in the vortex core in intimate contact with the arc 22, so that a highly reactive Plasma is produced at a relatively low temperature.
- This plasma is distributed in the transverse channel 32 and then enters partly through the slot 34 and partly also through the open ends of the transverse channel 32 and the annular channel 30 from the plasma nozzle.
- a plasma jet 36 in the form of a flat fan generated in the edge regions 38 a greater density and a greater flow velocity than near the nozzle axis having.
- the range of the plasma jet 36 at the edges is greater as in the middle, so that the downstream edge 40 of the plasma jet a has concave curvature and thus the subjects overall the shape of a Swallowtail accepts.
- This shape of the plasma jet ensures that the plasma jet fits snugly against the workpiece, not shown.
- Figure 3 shows a modified embodiment in which the annular channel and the transverse channel are absent and at the mouthpiece at the free end is bounded on both sides of the slot 34 by inclined surfaces with corresponding inclined surfaces of the housing 10 are flush.
- the housing 10 is here surrounded by an air distributor 42, by the auxiliary air 44 parallel to the inclined surfaces of the housing and the mouthpiece 24 from both sides blown out of the slot 34 plasma jet 36 is blown to the fan-shaped plasma jet to bundle and premature expansion of this To prevent plasma jet in the direction perpendicular to the plane of the fan direction.
- the auxiliary air also makes intimate contact with the plasma jet supported with the surface of the workpiece.
