    An apparatus and process for introducing and distributing a charge within a shaft furnace, the shaft furnace charging apparatus comprising an elongated charge distribution chute, the angle of which being adjustable in relation to the vertical axis of the furnace to allow for distribution of charge to desired areas within the furnace. The charge distribution chute includes a first end for accepting the charge and a second end for distributing the charge within the furnace. The first end of the chute is suspended from a supporting fork which is rotatable about its axis to provide for pivoting of the chute about a first axis when the support fork is rotated. The chute is suspended from the support fork to provide for pivoting of the chute about a second axis which is preferably perpendicular to the first axis. The direction of the chute within the furnace may be adjusted to provide for distribution of the charge to the desired area of the furnace.

    The invention relates to equipment for metallurgy units, namely, devices for loading shaft furnaces containing a distribution loading chute with swing and rotation mechanisms.
    The closest in technical essence and the achieved result to the proposed is a device for loading a shaft furnace, in which the groove does not turn along two orthogonal axes, but rotates around the vertical axis of the furnace with the possibility of adjusting its angular position relative to this axis. In this known device, the movement of the chute is carried out by two independent drives of rotation and swing of the chute using differential and planetary gear mechanisms. These drive mechanisms allow the chute to be directed to any orbital point of the surface of the charge and to load material into the furnace in accordance with the conditions of its optimal operation TI.
    However, the known mechanisms for mounting, fixing and driving the chute are very complex and therefore
    until now, they have not been applied in practice.
    The purpose of the invention is to expand the functionality of the device, simplify the design and maintenance, improve reliability and improve the charge of charge materials, regardless of the shape of the furnace cross section.
    The goal is achieved by
    It means that the device is equipped with a rotary ring-shaped saddle inside which the distribution chute is suspended, the rotation mechanism consisting of supporting the side wall of the upper part of the furnace, rotating around the horizontal axis of the sleeve with the fork-shaped part, between the ends of which is suspended, and the swing mechanism is designed as
    0 outside the furnace of the hydraulic cylinder, the reciprocating rod of which is pivotally connected to the saddle. The distribution chute in the upper cone-shaped part is provided with guides, between which the paws and the saddles are fixed upwards. The inner part is made fork-shaped, and the stem, bushing and plug are hollow and connected to the circulating system of the cooling agent.
    FIG. 1 schematically shows the mechanism of swinging the gutter; Fig 2, the mechanism for the hinge movement of the suspension; Fig. 1, section A-A; in fig. 3-5 are details of a preferred embodiment of the gutter suspension.
    The chute 1 is a tubular form hingedly suspended in a fork 2 installed in the side wall of the head 3 of the furnace. The plug 2 rotates along its longitudinal axis A, causing the trough 1 to swing, the installation and operation of WIL15I 2 is schematically shown in figs 1 and 2, the plug 2 is articulated with the sleeve 4 installed in the nest 5, which is sealed by a seal (fig 1) , Outside the furnace wall, the edge of the sleeve 4 is provided with a disk 6. The disk 6 is connected with the rod 7 of the hydraulic cylinder 8 (Fig 2). Here another type of drive is used, for example an electric motor.
    When the cylinder 8 is in operation, the disk b, the sleeve 4 and the fork 2 rotate on a common axis A, causing the chute 1 to rotate in the direction of one of the arrows in FIG. 2, depending on the direction of movement of the rod 7,
    In the bore of the sleeve 4 is installed coaxially to the axis And the pusher 9, which makes an axial movement. The pusher 9 is connected to the second hydraulic cylinder 10 (which can also be replaced by another drive). T ha 11, the ends of which are hinged respectively attached to the inner end of the pusher 9 on the groove 1, converts the reciprocating movement of the pusher into the swing motion of the groove 1,
    FIG. 3-5 shows in detail a preferred embodiment of the suspension of the chute 1. Sequentially shows a front, side and top view of where the seat 12 is to hold the chute 1. The saddle 12 includes a ring 13, the inner diameter of which slightly exceeds the outer diameter of the tubular part of the chute 1, and made at the same time with the ring 13, the paws 14, 15, 16 and 17, located axially and radially to the ring 13, the inclination of the paws relative to the axis of the ring 13 corresponds to the angle of the solution of the expanding part 1, and the groove so that the trough with its tubular part is inserted into the ring 1 3 and held by paws 14, 15, 16, and 17 and ring 13. Thus, groove 1 simply lies in the seat; e 12 and can be easily removed,
    To ensure better retention of the groove 1 in the saddle 12 and eliminate its rotation along the longitudinal axis, the outer wall of the groove 1 in the expansion part contains four pairs of guides cooperating with the legs 14, 15, 16 and 17. For simplicity, FIG. 3 shows one pair of guides. To facilitate insertion of the groove 1 into the saddle 12, each pair of guides in the lower part is slightly diluted, and the upper end of each is slightly tapered as shown in FIG. 3. Installing the paws between the guides ensures accurate positioning of the groove 1 without lateral displacement,
    The wall of the gutter is provided with an outer screen 18 of izarofarnogo steel and (internal coating 1U of a material with high wear resistance.
    Two opposite paws 14 and 15 of the saddle 12 are installed with the possibility of rotation at the ends of two branches of the fork 2 (Figs. 3 and 5). T ha 11 is also made in the form of a fork, covering its two branches 11, the saddle 12 and the groove 1, the ends of the branches 11 are pivotally mounted on the ring 13, and the opposite end of the rod is pivotally connected to the pusher 9. The hinge movement of the fork 2 around the axis A and backward -accessible movement of the pusher 9 causes a panic movement of the saddle 12 in two mutually perpendicular directions, and the combination of these movements causes the lower end of the groove 1 to move according to predetermined curves,
    The fork 2 is made hollow and coolant is continuously circulating inside this sleeve, fed through channel 20 in sleeve 4. Continuous circulation of coolant to the end of plug 2 causes the cooling components to cool continuously and ensures that the kiln operation conditions are normal. It may also be provided on the drawings to circulate a push rod 9 and 11 to the ends of both branches of the latter, the B version of the embodiment of FIG. 3-5 should provide for hermetic sealing through the joints between the pull 11I pusher 9,
    Thus, simple and one-sided mounting of the chute allows block disassembly of both the chute movement mechanism and the chute itself, as well as its accessories. Such a simplification and high speed of dismantling implies a significant reduction in stopping times of the furnace, necessary to replace defective parts, which increases the productivity of the furnace.

    The cardan gutter suspension and its ability to move along two reciprocally perpendicular planes simplifies and refines the motions of the gutter and makes it possible to establish an optimal furnace loading pattern. The main feature of the proposed installation is that there is an exact position of the groove in space, which is the intersection point of two swing planes. The design of the suspension mechanism and the drive allows the inert cooling gas to circulate through these mechanisms to their end and allows cooling of the rubbing surfaces, which increases the duration and reliability of the device as a whole. This cooling increases, besides that, the mechanical strength of the sliding parts and allows the use of cheaper and lighter construction materials. Claims i.
