Definitions
- the invention relates to an autogenous flame spraying device for flame spraying powdered materials or spray powder.
- the inventor has set himself the goal of creating a flame spraying device that has a considerably simplified construction of its torch body and allows cost-saving production with high accuracy. Furthermore, the flame spraying device according to the invention should cover a wide range of possible uses, ie it should be adaptable to a wide variety of spray materials and types of use.
- an autogenous flame spraying device for flame spraying powdery materials or soritz powder by means of -- supply lines for the spray powder and for fuel gas, oxidizing gas and acceleration gas or mixtures associated -- burner nozzle on a burner body made of at least two interchangeable basic parts, on one of which a Nozzle carrier for the detachable burner nozzle and a connection for a powder supply and channels for the spray powder and carrier gas are provided, the exchangeable nozzle carrier having at least one injector for mixing the fuel gas and the oxidizing gas and channels for supplying the gas mixture and a mixture of spray powder/carrier gas to the Has burner nozzle, whereas on / in the other base part of the burner body are connections for the supply of fuel gas, oxidizing gas and acceleration gas.
- control valves for the channels for fuel gas, oxidizing gas and acceleration gas should be assigned to this further base part - either outside of the actual base part or integrated into its channels.
- a parting plane of the torch body has proven to be favorable for this purpose, on which O-rings are provided for the gas seal at the transition between the two basic parts of the torch body.
- a further parting plane allows the nozzle holder to be attached to the burner body and is traversed by at least one plug-in element, which engages in the latter, for the non-rotatably fixed nozzle holder.
- the basic parts of the burner body are advantageously connected by a clamping or clamping device, by means of which interposed sealing elements can be clamped.
- Such a structure of the flame spraying device allows the burner body to be constructed on the one hand from a part which can be produced by machining -- in particular by drilling -- a workpiece made of rod material and the accuracy of which is therefore easily sufficient, and on the other hand from a part which only contains the feed and optionally has control devices for the various gases required.
- a completely modular design of the entire flame spraying device can be achieved and thus a hitherto unachieved range of use with all the advantages resulting from this for manufacture, use, operational organization, repair and maintenance, etc.
- connection levels provided on the center piece allow the attachment of easily replaceable parts by hand -- nozzle holder, powder supply adapter or the like. --, the opening of an axial powder channel makes it possible to insert a carrier gas injector in the case of internal delivery and the connection for the carrier gas-powder mixture in the case of external delivery.
- the screw-in carrier gas injector for sucking the powder from the powder container placed on the powder supply adapter can be equipped with a laser-drilled synthetic ruby for the injector bore to maintain the accuracy of the supplied powder quantity.
- the center piece Thanks to the described sides and surfaces of the center piece, not only the type of powder feed but also by changing the nozzle holder -- containing one or more injectors for the fuel gas/oxidizing gas mixture and the burner nozzle -- the performance of the fluff of the flame sprayer can be quickly and easily changed be changed.
- the design of the center piece also means that by changing the nozzle holder, the powder supply adapter and the carrier gas injector or the external powder supply channel, the construction of the flame spraying device can be coordinated in such a way that the entire range of application for oxyfuel flame spraying in terms of flame output, flame speed, powder quantity can be covered with just one device is able to be covered.
- the supply line housing or valve block In the other basic part of the burner body, the supply line housing or valve block, the connections for the supply of gases such as fuel gas, oxidation gas, carrier gas and acceleration gas with the control valves and the quick-acting valve are arranged.
- a supply line housing designed in this way makes it possible--corresponding to the center piece--to equip the burner body with one or more control valves, with or without a quick-acting valve for the gases, by exchanging them for the necessary conditions.
- the connections or supply lines for the gases can also be adjusted as desired using this process.
- the combination of the assembled device can be changed so that the entire range of sprayable materials -- from plastic to metals or metal alloys with or without hard materials, metal oxides and refractory metals -- can be used. - can process.
