摘要:
A machine and method is provided for piercing a taphole for a shaft furnace. The machine comprises a mounting, with a support installed on the mounting so as to support a rod at the front of the mounting, a rear support which can move on the mounting and is provided with means for being coupled to the rear end of the rod and a clamp mounted in a sliding manner on the mounting and designed to grip the rod at any place between the front support and the rear support. A powerful rotary motor installed at the rear of the mounting drives an endless chain installed axially in the mounting. A clamp attached to the endless chain moves during the insertion of the rod into the taphole clay by reversal of the direction of rotation of the motor in a to-and-fro motion between a position (B) at the front of the mounting and a position (A) which is located at a distance L from the position (B).

A machine is provided for piercing a taphole for a shaft furnace for applying the piercing rod method. The machine comprises a mounting, with a support for supporting the rod at the front of the mounting, a sliding support for supporting the rod at the rear of the mounting and a clamp, mounted in a sliding manner on the mounting and designed for gripping the rod at any place between the front support and the rear support. A travel multiplier is connected between a jack and the clamp so that the clamp may be moved. Means for controlling the jack make it possible to move the clamp in a to-and-fro motion between a position (B) at the front of the mounting and a position (A) which is located at a distance L from the position (B).

A machine is provided for piercing a taphole for a shaft furnace for applying the piercing rod method. The machine comprises a mounting (20), a drive means (42, 44), a clamp (34) for coupling the drive means to the rod (26) during its extraction. It is characterised by a push-member (34) transmitting the said thrust force to the rear end of the rod (26) during the insertion of the rod (26) into the taphole clay and by intermediate guides (55i) surrounding the rod (26) at several places during the insertion of the rod (26) into the taphole clay. The said guides (55i) being successively placed in a position in which they do not hinder the advance of the said push-member (34, 78) on the mounting (20).

The device is composed of several separate elements consisting of at least one central tubular element connected, on one side, by means of a first ball-and-socket joint and a first compensator to a first connector supplying preheated air and on the opposite side, by means of a second ball-and-socket joint and a second compensator to a second connector. In order to reduce the length of the device, the second joint is oriented in the opposite direction to the said first joint, its center of curvature being located on the axis of the said second connector on the inside of the latter.

The present invention relates to a handling device for a distribution chute of a shaft furnace, the said distribution chute being suspended pivotably on a rotary cage mounted by means of bearings in a housing installed in the head of the furnace and containing drive means for rotating the said cage about the vertical axis of the furnace and drive means for pivoting the chute about its horizontal suspension axis. The invention also relates to a mechanism for driving the chute which is suitable for this device.

The probe comprises a probe arm provided with a series of orifices for simultaneously taking gas samples and measuring the heat at different locations of the charging surface and penetrating through an opening in the furnace. This opening is surrounded by a support hoop integrally connected to the wall of the furnace and provided with two diametrically opposite outer journals on which are articulated two parallel arms supporting between them the probe arm. This arm can move about the center of the said hoop under the action of at least one actuator mounted between the said hoop and the outer end of the probe arm, the arm comprising a circular sliding surface moving, sealingly, over the inner surface of the said hoop.

A device for shutting off pipelines for the transport of bulk product is disclosed. The device comprises a housing with a circular passage orifice, a closing element mounted pivotably in the housing, and an annular gasket surrounding the said orifice and capable of interacting with the peripheral part of the closing element. The gasket is mounted on a fixed support, and the closing element is displaceable along an axis perpendicular relative to its pivot axis. The device is particularly adapted for pipelines for transport of coal dust.

A valve actuating device for a hopper is comprised of two spherical shaped shutters or registers which pivot about common suspension axles. Each of the registers is carried by two pairs of arms located on either side of the bottom of the hopper and is capable of pivoting about two axles mounted respectively on brackets fastened to the bottom on either side of the hopper. The supporting arms of one of the registers are connected respectively to the piston rods of two hydraulic jacks mounted pivotally on the brackets; and the first pair of supporting arms experiencing the action of the hydraulic jacks are connected respectively to the second pair of supporting arms by use of a linkage articulated on the bracket.

A furnace probe is introduced transversely into a furnace through a support block and a sealing packing. In order to reduce the influence of distortions on the packing and support elements, a carriage is slidably mounted along a frame and is provided with at least one stirrup mounted thereon so as to be pivotable about a horizontal axis at right angles to the direction of a device for gripping the probe and driving it in the probe insertion direction when the carriage is moved in the direction of the furnace.

A device for the distribution of materials in bulk comprises a chute (10) suspended from a first rotor (18) so as to be driven in rotation and to be capable of pivoting about a pivoting axis (33). A pivoting ring (38) is connected to the chute (10) so as to be capable of pivoting about an axis (36) perpendicular to the horizontal pivoting axis (33) of the chute (10). A guide means, preferably comprising a large diameter suspension bearing (52), is supported by a second rotor (40). It defines for the pivoting ring (38), in a reference frame attached to the second rotor (40), an inclined plane of rotation which makes an angle .alpha. with a horizontal reference plane. The pivoting ring (33) creates, during a relative rotation in this inclined plane of rotation, a pivoting of the chute (10) about the pivoting axis (33).
