    The invention relates to a device for the thermal coating of powdered materials. The purpose of the invention is to simplify the operation and expansion of technological capabilities. For this purpose, the combustion chamber of the focusing atomizer is made with a connector capable of moving one part of the focusing atomizer relative to another. The front part of the focusing atomizer is pivotally connected to the rear part with the possibility of rotation. The connector is made in the form of an inclined surface placed at an angle of 45-90 ° relative to the longitudinal axis of the focusing atomizer. It is possible to perform the connector in the form of steps. The front part of the focusing atomizer has a hinged protrusion for engaging with the rear part. The front part of the focusing sprayer may be installed with the possibility of displacement in the direction relative to the other part along the longitudinal axis. The connector surfaces of the two parts of the focusing sprayer are provided with sealing profile sealing parts made of refractory material. Both parts of the focusing sprayer are provided with locking elements. One of the parts of the focusing sprayer is provided with a handle. The nozzle-nozzle is made with a profile of the outer surface that coincides with the profile of the inner surface of the combustion chamber of the focusing atomizer. 10 hp f-ly, 6 ill.

    The device is made in the form of a combustion chamber 1 with a transitional circuit 2 for entering the channel 3. The combustion chamber 1 is set axially displaced relative to the nozzle 4 of the channel 3 of the burner nozzle 5 or the holder 6 with the nozzle 5. Focusing atomizer 7 in the area of the combustion chamber 1 made split transversely to the longitudinal axis 8 of the spray gun 7 and in front of the part 9 of the spray gun 7 is set movable relative to another part 10 mounted on the nozzle 5 or the holder 6 of the nozzle 5. In preferred embodiments (figs 1 and 3) with mating with the possibility of rotation of the front part 9 of the spray gun 7 and part 10, namely, so that part 10 was provided with a side support protrusion 11 and on it could be made in the form of a detachable hinge hinge protrusion 12 to simplify the replacement of the front part. In this case, it is advisable to make the hinged protrusion 12 of the front part 9 with the handle 13 (Fig. 1) 9 facilitating maintenance during the deviation and return processes. It is also possible to install a tension spring (not shown), which always presses or does not have the front part 9 of the sprayer 7, i.e. keeps her in working position. The surface 14 of the section can be made in the form of a step T5 (Fig. 1) and inclined (Fig. 3), preferably at an angle of 45-90 °. The coupling surfaces of the two parts 9 and 10 (Fig. 2) can be made with a sealing profile or with a refractory seal 16. In order to be able to deflect the front part 9 in the embodiments (Figs 1 and 3), it is necessary to move the holder so far back 6 sprayer or nozzle 5 no oTHOuieffMO to part 10 so that the front part 9, containing respectively the combustion chamber t, can be deflected. Considering

    the working positions of the holder b of the atomizer 7, in which the holder does not engage with the front part 9 of the atomizer 7 on both parts 9 and 10 in the area 14 of the connector (Fig. 1), the fixing elements 17 are installed. The biasability of the two parts 9 and 10 is ensured by that, in part 10, two appropriately profiled guides 18 are laid rigidly 0, extending parallel to the longitudinal axis 8 (Fig. 4). On these guides 18, the front part 9 of the atomizer is mounted with parallel displacement, due to which the nozzle 5- is axially released along the axis, taking into account the presence of a long handle (not shown) on the front part 9. Since during ignition the amount of flammable gas must be mi

    minimum, the section surface 14 in this embodiment is made passing in the zone of the combustion chamber 1, i.e. Most of the combustion chamber 1 and transition zone 2 are elements of the front part 9 of the nebulizer, which is desirable for technological reasons. The focusing atomizer has a cavity 19 for the passage of the refrigerant (FIG. 3). The necessary nodes for connecting the lines are not shown.
    The central supply of powder through the nozzle is not obstructed and may be undesirable depending on the type of powder. For such cases, in the front part 9 of the sprayer, in the zone of the junction with part 10 (FIG. 6), channels 20 are placed for supplying powder, to which corresponding lines (not shown) are connected, supplying the powder. The field of application of the device is expanded by the use of various powders.
    This ensures a significant displaceability of the burner nozzle inside the focusing spray tube in combination with the possibility of external supply, especially of powder to the focusing tube, which has not yet been used in pinch sprays of this type, probably due to the fact that Only the pinch effect was always used. External inlet, in particular powder, directly into the focusing tube-sprayer means a significant increase in the options in terms of the versatility of the device for the use of various powders.
    Immediately before the zone position E of the extreme displacement of the nozzle 5 - the burner in the wall 2 of the focusing atomizer 7%, exactly in the displaceable part, four single-tip channels 20 are installed with places 22 for attaching converging highways inclined to the longitudinal axis 8 in the direction of the flow exit (Fig. 6 ).
    The device works as follows.
    The front part 9 of the focusing atomizer 7 is displaced relative to part 10. Then a mixture of combustible gases is fed through the burner nozzle 5 and the combustible mixture is ignited in the combustion chamber 1. The front part S of the focusing atomizer 7 is returned to its original working position. 17. Next, install the necessary working decays of the components of the gas mixture and feed the powder through channels 20, which can also be used as inlet channels for additional gases, like air, combustible and inert gases, and for high calorific value liquid fuels. With a sufficient number of channels 20, you can use the suit of them for the approach of powder, and some - for the supply of additional gas.
    Due to the axial displaceability of the nozzle 5 using the spray gun holder 6, it is possible in a simple way, according to need, to rearrange the nozzle 5 from the extreme shifted position E to another position E ,, with the smallest displacement relative to the channels 20. Thus, various positioning opportunities arise. the flame of the burner with respect to the entry points of single-scoler channels 20. For this case, in terms of bias, the embodiment (Fig.) is preferable, since the places 22 which connect the supply lines when the focusing p is deflected Aspiration 7 by turning to some degree would be a hindrance.
