Definitions

  • the invention relates to a burner head for plasma sprayers according to the preamble of claim 1.
  • Plasma sprayers with a burner head designed according to the preamble of claim 1 are preferably used for coating cavity walls, such as those found in pipes, bores, channels and the like.
  • the electrode consisting of the anode nozzle and the cathode transversely to the longitudinal direction of the plasma spraying device, so that the longitudinal axis of the generated plasma jet runs transversely to the longitudinal axis of the plasma spraying device.
  • it In order to prevent the burner head from overheating during the coating process, it must have cooling, as a rule liquid cooling.
  • a plasma spray burner is known from EP-PS 0 171 793, which has the construction features described above.
  • This plasma spray gun has a cathode half-shell and an anode half-shell, which two shells are separated by an insulation plate.
  • a cathode arrangement called an electrode
  • a burner nozzle is used, both the cathode arrangement and the burner nozzle being easily exchangeably attached.
  • a cooling channel with an annular channel leading around the burner nozzle is provided. The ring channel is sealed off from the burner nozzle used by two O-rings. Additional cooling channels leading to the O-rings are provided for cooling these two O-rings.
  • a cooling channel is also provided, this being designed as an annular channel in the region of the cathode arrangement, which is not, however, led directly to the cathode arrangement.
  • the reason for this should be to be found in the fact that the O-rings lie at least on one side directly on the burner nozzle. Even if the cooling water flows around the O-rings on one side, there is still the risk that they will melt as a result of the action of heat on the side facing the burner nozzle, or change in such a way that sufficient sealing of the ring channel leading around the burner nozzle is no longer guaranteed . Even the slightest leakage of cooling water into the area of the electrode means that the burner is inevitably damaged or destroyed during operation.
  • Such a plasma spray gun is therefore only suitable for temporary use, particularly when coating cavity walls.
  • the spraying process In order to achieve a quality of the applied material layer that is as uniform as possible, it is also increasingly required that the spraying process not be interrupted for entire series of substrates to be coated. This can mean that a plasma spray gun is in continuous use for days. In order to survive such maximum loads, it is of course inevitable that the cooling is optimized or improved, since it is not possible with the existing plasma spray guns to carry out coatings and in particular internal coatings in pipes, ducts and the like over such a long period of time.
  • the burner head designed in this way makes it possible for the first time that in the region of the anode nozzle of the burner head there are no longer any seals for sealing the cooling duct leading around the anode nozzle.
  • the seals previously installed in this area which are particularly subject to extreme wear in the case of compact burner heads, high performance and long service life, or the seals required for sealing the cooling channel in an area within the burner head that is not subject to very high thermal loads be transferred.
  • a series connection of the cooling channels also enables larger cooling channels to be accommodated on the available cross-sectional area of the burner head, so that the cooling is thereby additionally improved.
  • the cathode arrangement is inserted from the inside of the cathode body into the cathode socket of the cathode body, and that the corresponding cooling channel section leads past the cathode arrangement on the rear. It is thus possible that the cooling duct section in the region of the cathode arrangement need not be designed as an annular duct. Thus, a cooling duct with a larger cross section, which also has a lower resistance to the medium flowing through it, so that the cooling capacity is increased again.
  • this design in the area of the cathode arrangement means that sealing elements, as are necessary in most plasma spray guns, can be dispensed with.
  • such a plasma spray torch has a much more efficient cooling than comparable other devices and is therefore also suitable for tough continuous use under unfavorable, thermal conditions.
  • a further, preferred embodiment of the plasma spraying device provides that the insulating body has a longitudinal bore along its two longitudinal sides, from which a plurality of transverse bores lead outwards. These bores are used to supply gaseous media, for example air, by means of which the heat sink itself is cooled and which can also be used to cool the applied layer or the substrate itself in the outflow area.
  • gaseous media for example air
  • the anode body also has a longitudinal bore along its two longitudinal sides, from which two longitudinal bores a plurality of transverse bores lead outwards, the longitudinal axes of which run radially with respect to the longitudinal axes of the longitudinal bores.
  • the cross section of the burner head is essentially trapezoidal. This design enables larger duct and line cross-sections than with a burner head with the same cross-sectional area and a round shape. In addition, this shape, again based on a round burner head with the same cross-sectional area, enables a larger spraying distance.
  • the burner head can be seen in a cross section and a longitudinal section. Since such burner heads in question are known from the basic structure, only to the essential components of the burner head shown here in connection with the invention. These components are a cathode body 1, an anode body 3 and an insulating body 2 as well as a cathode arrangement 4 and an anode nozzle 5.
  • the cathode body 1, the anode body 3 and the insulating body 2 are connected to one another along planes running parallel to the longitudinal axis 15 of the burner head, the insulating body 2 arranged between the cathode body 1 and the anode body 3, the two other bodies 1 and 3 are insulated from one another.
  • the insulating body 2 On the connection-side end face 16, the insulating body 2 has a flange 21 which covers the cathode body 1 and the anode body 3 on the end face.
  • the cathode body 1 has a cathode socket 11 accessible from the inside in the form of a screw socket, into which the cathode arrangement 4 consisting of a gas distribution ring 42 and the actual cathode 41 is screwed.
  • the anode nozzle 5 is firmly inserted into the anode body 3 without the use of sealing elements, and the attachment can be carried out by pressing in or preferably by brazing.
  • a cooling channel formed by a plurality of cooling channel sections 6 which opens into the insulating body 2 on the end face 16.
  • the cooling channel is deflected by 90 ° into the anode body 3, then leads past the anode nozzle 5, forming an annular channel 61, is then deflected again by 90 ° and opens into the cathode body via an opening 25 in the insulating body 2 1, in which it is in turn deflected by 90 °.
  • the cooling channel leads past the cathode arrangement 4 on the back and finally opens after a deflection by 90 ° into the insulating body 2, from which it is led out at the end.
  • Such a series connection of the cooling duct sections 6 mounted in the three bodies 1, 2, 3 enables the cooling duct cross section to be larger than is the case with conventional cooling ducts arranged in parallel.
  • the plasma gas necessary for the operation of the plasma torch is supplied via two gas channels 43 which open into the cathode body 1 at the end and lead laterally through the latter into the cathode socket 11. From the cathode socket 11, the plasma gas finally passes through bores 44 in the gas distribution ring 42 to the front of the cathode arrangement 4 and thus into the region of the arc to be generated.
  • the coating material is fed into the front of the anode body 3 embedded bore 31, which leads through the anode body 3 and opens essentially radially into the anode nozzle 5.
  • the cooling channel 6 leading in an annular channel 61 around the anode nozzle 5 need not be sealed off from the anode nozzle 5.
  • the seals which are usually arranged in the form of O-rings in this thermally highly stressed area can be dispensed with.
  • 3 O-rings 7 are provided in the transition area from the cathode body 1 to the insulating body 2 and from the insulating body 2 to the anode body 3, with recesses 71 in the corresponding bodies 1, 2 for receiving these O-rings are let in.
  • the insulating body 2 additionally has two longitudinal bores 22 which open at the end face into the insulating body 2 and lead through it along the two long sides to its end region.
  • a plurality of transverse bores 23 leading radially outward from the longitudinal bores 22 outward from the insulating body 2 are arranged along the length of these two longitudinal bores 22.
  • the anode body 3 also has two longitudinal bores 32 which open into the end face thereof and lead through it along the two longitudinal sides through to the end region.
  • a plurality of transverse bores 33 leading radially outward from the longitudinal bores 32 outward from the anode body 3 are in turn provided along these two longitudinal bores 32.
  • the transverse bores 33 provided in the anode body 3 and leading to the outside are arranged in three groups, each of these three groups leading out of the anode body 3 at a different angle, as seen in the longitudinal direction of the burner head.
  • these two bodies 2, 3 can be cooled on the one hand, on the other hand, it is also possible by means of these transverse bores 23, 33, the substrate parts surrounding the burner head during coating or to cool the applied coating. If coating is carried out in an inert gas atmosphere, argon, for example, can be used as the cooling gas, while during coating under normal atmospheric conditions, for. B. air can be used.
  • the burner head has a flattened shape on its top and bottom.
  • this shape enables cooling ducts with a larger cross-section to be realized than with a round head having the same overall cross-sectional area; on the other hand, this shape allows a maximum spraying distance to be achieved.
  • the burner head is shown in a side view. From this, the cross bores 23, 33 leading to the outside can be seen both in the insulating body 2 and in the anode body 3. Various supply lines 10 are also shown. Depending on the task, it is entirely conceivable that the number of transverse bores 23, 33 and the exit angle from the respective body 2, 3 are adapted to the desired cooling capacity. The amount of gas or air flow per unit of time that is blown out via these transverse bores 23, 33 can also be varied within a certain range and thus the cooling capacity can be changed.
  • the plasma powder feed line 31 also need not be designed as a separately replaceable module. If necessary, the entire anode body 3 is simply replaced.
  • the anode nozzle 5 is preferably made of a copper alloy, and tungsten can also be used, while the cathode body 1 and the anode body 3 are preferably made of brass, since on the one hand brass has good conductivity of the electric current and on the other hand can be easily machined.
