    The invention relates to a device for the hermatization of the central hole of the shaft furnace chamber. The purpose of the invention is to increase the performance of the device. The device consists of a sealing valve mounted on the control lever inside the working chamber and interacting with the seat located around the sealing hole. The mechanism for moving the valve has a full rotary support, around the axis of rotation in the sealing support of the chamber wall and connected to the other end of the control lever by means of a device providing axial movement of the valve in relation to its seat. To reduce the space required for the movement of the valve, the caliper of its movement mechanism is mounted so that the axis of rotation forms an acute angle with the vertical axis of the chamber opening. 1 hp ff, 7 ill.

    The invention relates to the mechanical equipment of metallurgical furnaces and can be used in metallurgy, mechanical engineering and other industries of the industry.
    The purpose of the invention is to improve the performance of the device. Due to the removal of the valve, which overlaps the central opening, along such a trajectory that will allow, when the valve is in the lowest position, fill the loading chamber to the highest filling device.
    Fig, 1 shows the proposed device, - (respectively, with the flap in the closed position, general. View; in Fig.2 - also, the flap in the open position, general view (a), top view (b); Fig, 3 - casing capacity of the bunker; Fig, 4 - device assembly, vertical section; Fig. 5 and 6 - bunker, in the process of loading; Fig. 7 - node I in Fig. 4.
    The device comprises a loading chamber in the form of a gateway 1 with a central opening 2 in the upper part, a double-arm pivotally mounted lever 3, a flap 4, a mechanism 5 for moving the flap in the form of a rotary support 6 fixed in a sealing sleeve 7,
    To eliminate the deep lowering of the flap when opening the chamber aperture, it is assumed that the caliper and the flap are arranged in such a way as to ensure less deep penetration of the flap into the gateway, i.e. the arrangement of the caliper 6 allows for the same gateway opening

    to ensure its best filling or, for the same filling of gateway 1, to increase the cross section of its opening,
    This possibility is achieved by positioning the caliper 6 (Fig. 1) in such a way that its axis of rotation X forms an acute angle with the horizontal plane, instead of its horizontal position. Due to the slope of the X axis, its intersection point with the vertical axis 0 of the furnace drops, which increases the distance to the valve 4, i.e. the radius of the sphere of movement of the valve. In the horizontal projection (Fig. 2b) it can be seen that the plane of movement of the center of the flap is offset by the angle if, and this angle is proportional to the inclination of the X axis with respect to the horizontal,
    Since, in the embodiment according to FIG. 2, the flap penetrates less deeply into the gateway 1 during the opening process, the maximum load level may be increased} This difference also follows from FIG. 3, where the maximum load level is shown at 10.
    I
    Advantageously, the inclination realized by the inclination of the axis of rotation of the shutter 4 becomes all the more significant the greater the inclination. Fig. 4 shows the preferred implementation of the use of the device. Thus, if the X axis is strongly tilted with respect to the horizontal, the angle significantly exceeds the angle of (Fig 1). Such a strong tilt lowers the intersection point of the X and 0 axes even more. Thereby, the radius of movement of the valve 4 is increased, as a result of which the gateway (FIG. 4) has a pear-shaped shape, a wider section of which is at the level of the path of movement of the valve,
    The end of the loading phase of the gateway is shown in FIG. 5-7, which correspond to the species shown in
    FIG. 1 and 2a, b. Taking into account the width of the sluice in the upper part, it is necessary to provide a distribution device for the feed material in order to ensure its direction to the peripheral area of the sluice. For this, the retention valve 8, which controls the outflow of the feed material through the hopper 9 and the gateway 1, is designed in the form of a cone and is moved in a vertical position by means of known means. To direct the feed material into the central region, the cone is lowered to the position shown by dotted lines. Towards the end of the loading phase, the cone gradually rises in order to deviate the trajectory of the loading of the feed material on the X axis and its direction into the peripheral area of the gateway, a 1.
