    The apparatus comprises a distribution spout and a hopper which has two containers mounted thereabove provided with sealing valves and a metering member. In order to simplify the weighing system, the hopper is independent of the mouth of the furnace and is located inside a sealed chamber. The hopper is suspended by a device which enables it to be coupled to the container which is being emptied and to be uncoupled from the container which is being filled.

    专利说明:

    This invention relates to a charging device for a shaft furnace.
    A device is known in which, at first, the metering valve of one of the tanks is opened to provide a quantity of material sufficient to form a barrier from the material above the hopper supply pipe, and the metering valve of the bunker is opened only after the barrier has been formed. To control the formation of this barrier and to be sure that it continues throughout the entire loading phase, both the bunker and the hopper, which communicates with it, are weighed separately and throughout the entire loading time, and produce signals the corresponding contents of the bunker, the maintenance of the tank and the sum of these values. .
    The formation of a barrier from the material in the bunker is necessary to ensure
    the vertical and central incidence of the feed material on the chute and thus the elimination of the horizontal and inclined components caused by the material sliding along the sloping walls of the bunker.
    The need for separate weighing of the hopper and tank complicates the weighing and the signal processing system delivered by the weighing devices. In addition, it is necessary to provide several sections with compensators for a flexible connection. However, such compensators are the most sensitive places, which reduces the reliability of the device.
    The purpose of the invention is to simplify the design.
    The proposed device is characterized by the fact that, from the point of view of statics, the bunker does not depend on the furnace head, since it is located inside a sealed chamber, opioid

    It is suspended on the frame or on the furnace head, and is suspended by means that allow it to be attached to the tank, which is emptied, and detached from the tank, which is in the filling state.
    The hopper hangers consist of the first pull-rod located axially above the bunker, the lower end of which is connected with the first cross-arm to the upper part of the bunker, and the second pull-rod independent of the first one, which is hollow and located coaxially around the first pull-rod, the lower end of the latter is connected with the second cross-bar with the upper part of the bunker, both of which are attached by their upper ends to the piston of the first and second hydraulic cylinders, respectively, which are associated respectively with each of the two tanks.
    The bunker has flexible means of horizontal stabilization, which do not interfere with its freedom in the vertical direction.
    In Fig.1 schematically shows the proposed device, the cut; figure 2 - bunker, axial vertical section, rotated by 90 ° with respect to the view in figure 1; fig and 3 - details of the suspension of the hopper.
    The upper part of the casing 1 contains a chute drive mechanism for distribution of the feed material located in the head of the shaft furnace (not shown). Two billet tanks 2 and 3, located adjacent to both sides of the vertical axis O of the furnace, rest on weighing devices 4 mounted on frame 5, which rests on rack 6, which can transmit force to the furnace wall. To ensure the weighting of tanks 2 and 3, they are not connected to frame 5, with the exception of flexible plates 7 and 8, which ensure their horizontal stability, do not constrain their vertical freedom with respect to weighing devices 4 and frame 5.
    In addition, tanks 2 and 3 are equipped with upper sealing flaps 9 and 10, lower retaining flaps 1.1 and 12, as well as lower sealing flaps, the structures of which are known (figure 1 shows one sealing flap 13 connected to reservoir 2) ,
    Between the two tanks 2 and 3 there is a sealed chamber 14, which can communicate with each of the two tanks 2 and 3 through the opening of the lower sealing flaps 13. The sealed chamber 14 is connected to the interior of the furnace through the casing 1 with only one compensator 15 of the device, which is necessary for
    the operation of the sliding gate 16, provided directly above the casing 1.
    Inside the hermetic chamber 14 there is a hopper 17 in the shape of a funnel, which
    provided with a lower pipe 19 filing.
    The bunker 17 is freely suspended by means of the first traverse 19 to the first axis t 20, moving along the central axis 0, and the second traverse 21 to
    The second axial rod 22, which is hollow and located coaxially around the first rod 20, remains, however, completely independent of it. The gigs 20 and 22 exit the hermetic chamber 14 through the bellows 23.
    5 of the seal that surrounds the outer tube 22 in a hermetic manner without interfering with the freedom of its vertical movement. Inside chamber 14, each of t g 20 and 22 is connected with its machines by flexible plates 24 and
    0 25, which provide horizontal stability of the bunker 17, without interfering with its free vertical movement. Additional stabilization of the hopper 17 is provided by a flexible plate 26 connecting it with the wall of the chamber 14.
    The metering valve 27, as well as its drive mechanism 28, are attached to the hopper 17 through vertical skirts 29 and 30 rigidly associated with them. The drive shafts, couplings of the drive mechanism 28 and the shutter 27, intersect the bottom wall of the chamber 14 with the aid of a flexible sealing device 31, which retains the freedom of vertical movement of the metering shutter 27 and its
    5 drive mechanism 28.
    The suspension of the hopper 17 and its mounting on the tank 2 or 3 is carried out as follows.
    The upper end of the hollow t gi 22 rigid
    0 is connected to the console 32, the upper part of which has two parallel lugs 33 and 34 intersecting the axis 35, which is free around its horizontal axis in the sidewalls 33 and 34. The axis 35 is connected through the lug
    5 to 36 with a hydraulic cylinder 37. T ha 38 of the piston 39 of the cylinder 37 is attached to the tank 3 by means of a horizontal bracket 40 rigidly connected to the tank.
    0 The upper end of the thrust 20 is in turn connected to the reservoir 2 in the same way as the console 32 relative to the reservoir 3 (therefore, the same positions are used to illustrate the attachment of the thrust 20 to the reductor 2
    5 but with superscript).
    Since the ha 20 is free with respect to the hollow 22, the annular space between these rods, ensuring this freedom, is subject to the pressure acting inside the bunker 17. Therefore, it is necessary to provide a flexible sealing gasket 42 between the head 41 of the inner rotor 20 and the base of the arm 32, which is rigidly connected to the outer link 22.
    Work coupling the hopper 17 with tanks 2 and 3.
    In the case shown in Fig. 3, the annular space around the piston rod 38 of the piston 39 is filled with hydraulic fluid under pressure, which is in the cylinder 37 as well as the rod 20, i.e. the hopper 17, as well as its metering valve 27 and the drive mechanism 28, is connected to the tank 2 in such a way that its weighing by means of the weighing device 4 gives an indication of the contents of the tank 2 and the contents of the bunker 17. The cylinder 37 is not affected by pressure, t . is free relative to the piston 39, and the weight of the hopper 17 does not have any effect on the reservoir 3 (it is in the loading state, and its weighing devices 4 give signals indicating the degree of its filling).
    After the filling of the tank 3 is completed, and the tank 2 is unloaded through the hopper 17, by manipulating various valves, the tank 2 is filled and the tank 3 is unloaded. At this very moment, the bunker 17 must be disconnected from the tank 2 and linked to the tank 3. For This annular space around the piston rod 38 is connected to the pressure for maintaining the cylinder 37. As a result, it takes the load from the hopper 17 through the console 32 and the load 22, which is from that moment attached to the tank 3. At the same time the pressure in the cylinder 37 drops, which means the separation of the cylinder 37 and the hopper 17 from the reservoir 2.
    Instead of suspending pistons 38 and 38 from tanks 3 and 2, as well as transferring the load of rods 22 and 20 to cylinders 37 and 37, it is possible to turn them over and suspend them to tanks 3 and 2 in order to transfer the loads from 22 and 20 tons to tons gi pistons 38 and 38.
