    The invention relates to improvements in kilns for firing carbon blocks. The purpose of the invention is to obtain a tight connection of the pipe to the vent by eliminating the effect of the deformation of the furnace chambers in the longitudinal and transverse directions. The tube for the chamber furnace contains a main body equipped with transition nozzles 10 to which the nozzles are connected in an amount equal to the number of heating walls forming the furnace chambers, each of these nozzles being fitted to the holes called vents 8 located in the upper parts of each heating partition. Each nozzle is formed by at least two tubular elements arranged in series: the top element 15 is provided, on the one hand, with a flat washer, which interacts in a mode of connection and rotation with a flat flange 19, and, on the other hand, a flat flange 26, which interacts in the mode of connection and rotation with a flat flange 25 placed in the upper part of the third tubular element 16. Moreover, the upper tubular element 15 and the third tubular element 16 have at least part of their height the axis at an angle relative to axes perpendicular to the plane of the flanges. The device allows simultaneous lowering of the lower part of the nozzle and ensuring its rotation with tightness of the pipe joints on the vents. 6 hp f-ly, 6 ill.

    The invention relates to a technique for improving furnaces with open chambers for firing carbon blocks.
    FIG. 1 shows a carbon block kiln, general view; in fig. 2 - the same, isotherms | in fig. 3 - rotatable nozzle, adjustable along the axes X, Y and Z, a section (. The control system which is located behind the section plane is shown by broken lines.); in fig. 4 and 5 are the same examples of execution; in fig. 6 - section A-A on yig.Z.
    The furnace for burning carbon blocks has heating walls 1, connected in the upper part by pipes 2 with pipe 3, which is connected to a common collector 4. In cells 5 carbon blocks 6 are placed.
    The intermediate walls 7 of the heating walls 1 serve to lengthen the trajectory of hot gases and to average the temperature in the wall.
    In the upper part of the chambers (.or transverse walls) are located closing-off vents 8, pipes 3 for injecting or sucking air, and in some cases measuring instruments. The successive chambers are separated by transverse walls 9. The major axis of the furnace is indicated by the line XX1.
    Each nozzle 2 of the suction pipe 3 is tightly connected to the outlet of the chamber 8. The upper part of the nozzle is connected to the pipe 3 by means of an adapter nozzle 10, in which usually a butterfly valve 11 is placed, allowing the flow in each chamber to be controlled.

    The vertical part of the lower tubular element, which enters into the vent, is made rotatable with the possibility of combining the axis 12 of the lower part of the pipe with the axis 13 of the vent.
    The swiveling nozzle 14 allows to compensate for the deviation of the axes of the order of ± 50 mm (axes X and Y). And the deviation of the order of i 50 mm in height (.os Z).
    To achieve alignment along the axes X and Y and along the transverse axis of the furnace, the rotatable nozzle contains at least two elements: an upper tubular element 15, which is connected to the rotary nozzle 10, the straight portion of which is connected to the pipe 3, and the third tubular element 16 for adjustment in X and Y. The lower tubular element 17, which is connected to the outlet 8, allows for adjustment in Z (height).
    The upper tubular element 15 has an upper cylindrical part equipped with a washer 18 connected to the flange 19 of the rotary nipple 10. These two flanges are sealed, and the tubular element 15 can rotate relative to the flange 19. The washer 18 is pressed against the flange 19 by means of counter flange 20. Between the washer 18 and flange 19, it is possible to install an airtight gasket that is resistant to high temperatures (500 - 600 ° C), for example, such as metal-plastic (copper + mineral fibers). It can also be made by simply stuffing an oil, resistant to high temperatures, supplied to the gap 21 between flanges 18 and 19 by means of an oiler.
    The upper cylindrical portion of the upper member and the straight portion of the rotary nozzle 10 are coaxial.
    The axis 22 of the middle part 23 of the upper tubular element can be set at an angle ott to the vertical, for example, 20-45,
    The lower cylindrical part 24 of the upper tubular member is offset relative to the upper one by a distance equal to the maximum expected deviation between the axis 13 of the vent and the axis of the transition element 10. This maximum value may be, for example, 50 mm.
    The third tubular element 16 also has an upper cylindrical part with a flange 25, which cooperates with the flange 26 of the lower part 24 of the upper tubular element 15, the middle cylindrical part, the axis 28 of which is set at an angle equal to about axis 27, and the cylindrical lower part, the axis of which is offset relative to axis 27 by a distance equal to the maximum deviation, for example 50 mm.
    Z offset compensation, i.e. along the vertical axis of the furnace (Fig. 2), is provided by the lower tubular element 17, which is tightly fitted to the outlet 8.
    According to FIG. 3, the lower tubular member 17 rests on the gasket 29 in the groove 30 along the periphery of the vent. The sealing gasket is made resistant to high temperatures, for example, from mineral spun or woven fiber. In addition, the lower tubular element 17 can be stuck with the help of t g, the lower part of which is embedded in the furnace masonry.
    The third tubular element 16 and the lower tubular element 17 interact through the nozzle. L, which allows to compensate for the level deviation between the inlet of the vent and the lower part of the turning nozzle 14.
    Taking into account thermal expansion and possible defects in horizontal position of the holes, the implementation of a completely hermetic sliding nozzle is difficult. This tightness can be ensured by a heat-resistant bellows 32, resistant to temperatures of the order of ZiO-400aC. It is executed

    for example, fiberglass impregnated with a fluorocarbon polymer.
    Bolt holes are drilled in the flanges and counter flanges for fixing the entire mechanism. Free rotation is ensured by the presence of a grease, resistant to high temperatures, supplied to the space between the flanges using oil cans. In addition, the third tubular element 16 has a control device in the form of a double crank system, which allows simultaneous axial alignment of the axes, i.e. along the transverse axis of the furnace, maintaining or correcting the X axis alignment. After aligning the X and Y axes, the same device allows the lower tubular element 17 to be lowered before contact with the outlet 8 and aligned with the Z axis. The control device is made symmetrically with respect to the plane passing through the axis 33, contains a horizontal axis 34, diametrically intersecting the third tubular element 16 and having at its two ends the disks 35 and 36 and the radial handles 37 and 38 of the control, and connected by means of a hinge 39.40, not bb about the axis 34, the upper ends of rods 41 and 42 whose lower ends are hinged connections 43 and 44 fixed to the lower tubular member 17.
    The device works as follows.
    With a maximum lift of the lower tubular element 17, the suction pipe is installed and the operator notes possible deviations between the axis 13 of each vent and the axis 12 of the lower tubular element 17.
    Using the handles 45, the operator t aligns the axes 13 and 12 along the X axis, i.e. along the major axis of the furnace, then using the handles 37 and 38, it aligns the axes 13 and 12 along the Y axis, i.e. by pop

    the river axis of the furnace, maintaining or correcting the alignment along the X axis. When the axes 13 and 12 are aligned, the adjustment is carried out along the Z axis, i.e. lower the lower tubular element 1 / until contact with the groove of the vent 8. This operation is also carried out with the help of the handle 37 and 38, but by turning around the axis 34. The direction of the lower tubular element 17 when
    its alignment along the Z axis (elevation or lowering.) is provided by a groove 46 made in the third tubular element 16 in which the protrusion 47 slides 5, which is integral with the element 17.
    The design of the upper 15 and third 16 tubular elements can be simplified, as shown in Figures 4 10 and 5, by partially or completely eliminating the cylindrical parts with the vertical axis and retaining only the middle parts with the axis at an angle oi.
    The device allows 15 to simultaneously lower the lower part of the nozzle and. to ensure its rotation, increases the ease and accuracy of operations and, thus, ensures the tightness of the connections of the inlet or exhaust 20 pipes at the vents.
