Description

Aug. 4, 1970 P. E. CORBIAU JOINT CONNECTING ROTARY FURNACE WITH FLUE Filed May 9, 1967 Fig.2
INVENTOR P UL Emma s/Au H/s' ATTORNEYS US. Cl. 26618 3 Claims ABSTRACT OF THE DISCLOSURE A joint for connecting a rotary furnace with a flue which receives gas from the furnace. A cylindrical rotating member is connected with the rotary furnace to turn therewith and forms a passage for the gas from the furnace into the flue. An annular flange is pressed against a surface of the stationary flue while an annular movable member is applied with pressure against the rotary cylindrical member as well as against this flange, so as to prevent passage of air from the surrounding atmosphere into the furnace and passage of gas from the furnace into the surrounding atmosphere.
This invention relates to improvements in furnaces adapted to rotate around an axis, more particularly to metallurgical converters and to their joints provided between members connecting the inside of the rotating furnaces to the inside of a fixed outer enclosure, for instance a flue.
It is known that one means for exhausting the gases from: a furnace of this type, is to establish a permanent side communication, having for instance the form of a siphon, between the furnace and the flue, through the intermediary of a joint adapted to prevent the admission of air from the outside atmosphere into the furnace, thus allowing to obtain a rich gas, having for instance a high percentage of S gas.
The present invention consists in a joint for a furnace adapted to rotate about an axis, which joint is situated between the furnace and a fixed enclosure for example a flue, and is characterized in that resilient means are provided to press the joint against the said fixed enclosure and means are also provided continuously to take up all Wear of the contacting surfaces, so as to prevent the passage of air or of gases from the surrounding atmosphere into the furnace, or vice versa.
Other characteristic features will appear from the description which follows with reference to the accompanying drawings.
In the drawings, 1 shows in a longitudinal section a metallurgical converter embodying a joint according to the invention.
FIG. 2 shows a detail.
Referring now to FIG. 1, the gases from the converter 1 are sent to a flue 5 through a side passage 2, 4 having the shape of a siphon, followed by a movable cylindrical ring 3, leading to a flue 5, as shown by the arrows.
The cylindrical ring 3 is connected to the body 1 of the converter, and is adapted to rotate around its axis together with the latter. The fixed annular flange 6 is applied against the flue 5 which receives the gases from the converter through the intermediary of the cylindrical ring 3 in the direction of the arrows.
The space between the movable ring 3 and the flue 5 United States Patent 0 ice is made tight by an annular member 7 pressed on the one hand against the surface of the flue 5 through the flange 6 by means of pressing members 8, and on the other hand against the said movable ring 3, through the intermediary of packing means 9, such as asbestos, which are pressed against the ring 3 by springs 10.
One or several legs 11 fixed to, or integral with the member 7 are provided with grooves 16 open at one end (see FIG. 2), which receive a rod 12 fixed to one or several angle pieces 13 attached to, Or integral with the ring 3, and leaving a play for the sliding of the member 7, during the movements in one direction or the other of the whole joint.
This arrangement prevents the member 7 from rotating independently from the cylindrical ring 3, but allows a cross movement of the member 7, suflicient to obtain a continuous and uniform pressure of said member against the flue.
The pressure of the member 7 against the flue is obtained in the example illustrated in FIG. 1 by means of several pushers acting under the pressure of springs 14 bearing on the one hand against the flue and distributed around the member 7 and on the other hand against a member 8 which bears against an extension 17 of the member 7 by means of a roller 15 fixed to the member 8.
What is claimed is:
1. A joint connecting a furnace rotating about an axis with a flue which receives gas from said furnace, comprising a cylindrical rotating member connected to the body of said rotating furnace and forming a passage for the gases from the furnace into the flue, an annular flange applied against the flue, an annular movable member pressing against said cylindrical rotating member and against said annular flange, and packing means pressing against the cylindrical rotating member.
2. A joint for connecting a furnace rotating about an axis with a flue, as claimed in claim 1, in which the said flange has a plane surface, and springs are provided to exert a pressure upon the said plane surface.
3. A joint connecting a furnace rotating about an axis with a flue, comprising a cylindrical rotating member connected to the body of the said rotating furnace and forming a passage for the gases from the said rotating furnace into the flue, an annular flange applied against the flue, an annular movable member applied with pressure against the said cylindrical rotating member and against the said annular flange, resilient means applied against the said cylindrical rotating member, an extension of the said annular movable member and fixed means secured on the said cylindrical rotating member, interconnecting the said extension and the said fixed means with a play between them, to permit a sliding movement of the said cylindrical rotating member relatively to the said fixed means.
