Definitions
- the invention relates to a plasma nozzle for the treatment of surfaces, in particular for the pretreatment of plastic surfaces, with a tubular, electrically conductive housing which forms a nozzle channel through which a working gas flows, 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 AI and is used, for example, to pretreat plastic surfaces so that the application of adhesives, printing inks and the like to the plastic surface is made possible or facilitated.
- Such pretreatment is necessary because plastic surfaces cannot be wetted with liquids in the normal state and therefore do not accept the printing ink or adhesive.
- the pretreatment changes the surface structure of the plastic so that the surface can be wetted by liquids with a relatively high surface tension. The surface tension of the liquids with which the surface can just be wetted represents a measure of the quality of the pretreatment.
- the known plasma nozzle achieves a relatively cool, but highly reactive plasma jet, which has approximately the shape and dimensions of a candle flame and thus also allows pretreatment of profile parts with a relatively deep relief. Because of the high reactivity of the plasma jet, a very short pretreatment is sufficient so that the workpiece can be moved past the plasma jet at a correspondingly high speed. Due to the comparatively low temperature of the plasma jet, the pretreatment of heat-sensitive plastics is also possible. Since no counter electrode is required on the back of the workpiece, the surfaces of any thick, block-like workpieces, hollow bodies and the like can also be pretreated without any problems. For a uniform treatment of larger surfaces, a battery consisting of several offset plasma nozzles has been proposed in the publication mentioned. In this case, however, a relatively high expenditure on equipment is required.
- the object of the invention is therefore to create a plasma nozzle which, despite a very compact construction, can treat workpiece
- the geometry of the plasma jet can be effectively changed by using such an outlet slot.
- the plasma jet no longer has the shape of a candle flame, but experiences an extreme widening within the slot, so that a large-area, yet uniform plasma treatment of the workpiece surface is made possible. If there is an extended workpiece surface in front of the mouth of the plasma nozzle, the plasma flows outward at the diverging edges of the fan, and a negative pressure forms inside the fan, with the result that the fan-shaped plasma jet literally adheres to the workpiece " sucks in "so that the workpiece surface comes into intimate contact with the reactive plasma and thus a very effective surface treatment is achieved.
- the working gas can be swirled in the nozzle channel.
- the twisted plasma jet can also be expanded in a fan shape using the outlet slot. At most, the swirl leads to a slight S-shaped distortion of the fan when one looks frontally at the mouth of the plasma nozzle.
- the intensity distribution of the plasma over the length of the slot can be controlled, for example, by varying the width of the slot over the length.
- a cross-channel with a larger cross-section running parallel to this slot is arranged immediately upstream of the slot, in which the plasma can distribute itself before it enters the actual outlet slot.
- This arrangement can be produced particularly easily if the mouth of the nozzle channel, including the slot and the transverse channel, is formed by a separate mouthpiece made of insulating material (ceramic) or preferably of metal, which is inserted into the coin. the housing is pressed or screwed in.
- the transverse channel is preferably open at both ends, and these open ends are only surrounded by the walls of the housing at a certain distance, so that part of the plasma can escape from the transverse channel at the ends and then through the housing walls obliquely towards the workpiece is distracted.
- the plasma fan is then delimited on both edges by particularly intense marginal rays that literally pull the fan apart.
- the shape of the fan and the intensity distribution of the plasma beam within the fan can be set, for example, in such a way that the downstream edge of the plasma fan assumes a concave shape, so that the fan resembles a dovetail.
- the contour of the fan can be varied by varying the depth at which the open ends of the transverse channel lie in the housing of the plasma nozzle, so that, if necessary, a convex curvature of the downstream edge of the fan can also be achieved.
- auxiliary air can be supplied to the outer surface of the housing of the plasma nozzle on both sides of the fan plane.
- the outer surface of the housing of the plasma nozzle in the mouth area is not conical but rather prism-shaped, so that two flat surfaces are formed which converge to the plane of the fan.
- FIG. 1 shows an axial section through the plasma nozzle.
- 2 shows an axial section through the plasma nozzle in the direction perpendicular to the section plane in FIG. 1;
- Fig. 3 shows a section analogous to Fig. 2 for another embodiment.
- the plasma nozzle shown in the drawing has a tubular housing 10 which forms an elongated nozzle channel 12 which tapers conically at the lower end.
- An electrically insulating ceramic tube 14 is inserted into the nozzle channel 12.
- a working gas for example air, is fed into the nozzle channel 12 from the upper end in the drawing and is swirled with the aid of a swirl device 16 inserted into the ceramic tube 14 in such a way that it flows in a vortex shape through the nozzle channel 12, as in the drawing through a symbolizes helical arrow.
- a vortex core is thus formed in the nozzle channel 12, which runs along the axis of the housing.
- a pin-shaped electrode 18 is mounted on the swirl device 16, which projects coaxially into the nozzle channel 12 and to which a high-frequency alternating voltage is applied with the aid of a high-voltage generator 20.
- the voltage generated with the aid of the high-frequency generator 20 is of the order of a few kilovolts and has, for example, a frequency of the order of 20 kHz.
- the housing 10 which is made of metal, is grounded and serves as a counterelectrode, so that an electrical discharge can be caused between the electrode 18 and the housing 10.
- an electrical discharge can be caused between the electrode 18 and the housing 10.
- This corona discharge ignites an arc discharge from the electrode 18 to the housing 10.
- the arc 22 of this discharge is carried along by the swirling working gas and channeled in the core of the vortex-shaped gas flow, so that the arc then runs almost linearly from the tip of the electrode 18 along the housing axis and only radially in the region of the mouth of the housing 10 branched onto the housing wall.
- a cylindrical copper mouthpiece 24 is inserted into the mouth of the housing 10, the axially inner end of which is attached to a shoulder 26 of the housing. lies.
- the conically tapered end of the nozzle channel 12 continues in the mouthpiece 24 continuously, with the same or slightly changed cone angle.
- the arc 22 branches inside the mouthpiece 24 onto the conical walls of the mouthpiece.
- the mouthpiece 24 has, at the free, lower end in FIG. 1, a section 28 with a reduced diameter which, together with the peripheral wall of the housing 10, forms an annular channel 30 which is open in the opening direction.
- the conically tapered tip of the nozzle channel 12 opens into a transverse channel 32, which is formed by a transverse bore in the section 28 and is open at both ends to the annular channel 30.
- This transverse channel 32 which according to FIG. 2 has a circular cross section, is axially followed by a narrower slot 34, which runs diametrically through the mouthpiece and is open to the end face of the mouthpiece.
- the swirling working gas flowing through the nozzle channel 12 comes into intimate contact with the arc 22 in the vortex core, so that a highly reactive plasma is generated at a relatively low temperature.
- This plasma is distributed in the transverse channel 32 and then emerges from the plasma nozzle partly through the slot 34 and partly also through the open ends of the transverse channel 32 and the annular channel 30.
- a plasma jet 36 is generated in the form of a flat fan, which has a greater density and a greater flow velocity in the edge regions 38 than in the vicinity of the nozzle axis.
- the range of the plasma jet 36 is greater at the edges than in the middle, so that the downstream edge 40 of the plasma jet has a concave curvature and the fan as a whole takes the form of a dovetail.
- This form of the plasma jet ensures that the plasma jet nestles well against the workpiece, not shown.
- FIG. 3 shows a modified embodiment in which the ring channel and the transverse channel are not present and in which the mouthpiece is delimited at the free end on both sides of the slot 34 by inclined surfaces which are flush with corresponding inclined surfaces of the housing 10.
- the housing 10 is here surrounded by an air distributor 42, through which auxiliary air 44 is blown from both sides onto the plasma jet 36 emerging from the slot 34 parallel to the inclined surfaces of the housing and the mouthpiece 24, in order to bundle the fan-shaped plasma jet and to prematurely expand it this Prevent plasma jets in the direction perpendicular to the fan plane.
- the auxiliary air also supports intimate contact of the plasma jet with the surface of the workpiece.
