Autogenous flame spraying apparatus for the flame spraying of powder-form materials or spray powder
| Details |
Inventors: Simm, Wolfgang; Steine, Hans-Theo; Sommer, Peter;
Assignee: Eutectic Corporation (Flushing, NY)
Primary Examiner: Kashnikow; Andres
Assistant Examiner: Morris; Lesley D.
Attorney, Agent or Firm: Bachman & LaPointe
An autogenous flame spraying apparatus includes a supply line housing having gas supply lines for combustion gas, carrier gas and acceleration gas; a main housing connected to the supply line housing and having a supply line for a spray powder, and ducts communicating with the gas supply lines, the housing having a first injector for mixing the spray powder and the carrier gas to form a first mixture; an interchangeable nozzle carrier for carrying a releasable torch nozzle, the carrier being releasably attached to the main housing and having a second injector for mixing the combustion gas and the carrier gas to form a second mixture, the nozzle carrier also having ducts for conveying the first mixture and the second mixture to the torch nozzle, whereby the carrier can be replaced so as to alter both flame power and feed of spray powder. |

DETAILED DESCRIPTION That object is attained by an autogenous flame spraying apparatus for the flame spraying of powder-form materials or spray powder by means of a torch or burner nozzle associated with supply lines for the spray powder and for combustion gas, oxidation gas and acceleration gas or mixtures thereof, on a torch body comprising at least two interchangeable main portions, on one of which are provided a nozzle carrier for the releasable torch nozzle and a connection for a powder feed and ducts for the spray powder and carrier gas, wherein the interchangeable nozzle carrier has at least one injector for mixing of the combustion gas and the oxidation gas and ducts for the feed of the gas mixture and a mixture of spray powder/carrier gas to the torch nozzle, whereas provided on/in the other main portion of the torch body are connections for the supply of the combustion gas, oxidation gas and acceleration gas.
In addition, regulating valves for the ducts for combustion gas, oxidation gas and acceleration gas are to be associated with said further main portion - that being either outside the actual main portion or however integrated into ducts thereof.
For that purpose, it has been found desirable to provide a separation plane in respect of the torch body, at which 0-rings are provided for gas sealing purposes at the transition between the two main portions of the torch body.
A further separation plane permits fitment of the nozzle carrier to the torch body, while at least one plug element which engages into said body for the non-rotatably fixed nozzle carrier passes through the separation plane.
Moreover the main portions of the torch body are advantageously connected by a holding or clamping means, by means of which interposed sealing elements can be clamped in position.
It has been found advantageous for the described separation planes to be disposed substantially perpendicularly to each other, but in certain constructions they may also be disposed in mutually opposite relationship
