    Feeder box raw material opening device of steelmaking process
    The present invention relates to a device for opening the raw material stayed in the storage hopper in the process of storing and ejecting the raw material in the storage hopper in all fields of the steelmaking process, including the converter is a steelmaking process, more specifically to transmit the vibration force The present invention relates to a raw material opening device of a feeder box for opening a raw material remaining in the center of a hopper at a lower end of a feeder box.
    In general, the use of raw materials in the steelmaking process for refining molten iron and molten steel using subsidiary materials (Flux) or ferroalloy is performed by operating the vibrator 2 as a raw material stored in the ground hopper 1 as shown in FIG. It is discharged and conveyed to the road hopper (6) installed in the height area through the belt conveyor (5a, 5b) driven by the roller (3a, 4a; 3b, 4b), and then the converter through the inlet (7) during molten steel Put in (8).
    In such a raw material conveying system, when the raw material is caught in the hopper, it is necessary to open it. As a technique for solving the problem, there are the following conventional technologies.
    First, as shown in FIG. 2, the vibration of the feeder box 10 to which the vibrator 11 such as a feeder whose raw material stored in the storage hopper 6 of raw material such as ferroalloy is controlled by the control device 12 is attached. By discharging the raw material by means of the raw material component to be added to the receiving ladle 14 through the input chute 13, the raw material stays at the lower end of the storage hopper (6).
    At this time, the worker taps the outer portion of the hopper 6 using a tool such as a hammer 15c to shock the opening of the stayed raw material, or as shown in FIG. 3 of the hopper 1 by using the round bar 15a. The raw material retained in the hopper was opened at the top, or a round bar 15b bent between the gaps of the feeder box 10 was inserted into the hopper 1 to open the raw material retained in the hopper.
    In addition, recently, as shown in FIG. 4, the cylinder 16 is installed at the upper end of the hopper 6, and the shaft 18, which is operated up and down by the cylinder, is coupled to the connecting portion 19 of the rod to the inside of the hopper 6. And a technique for opening the raw material retained in the hopper 6 by using an opening mechanism having a plurality of opening protrusions 17 attached to the outer peripheral surface of the shaft 18.
    However, the above-described raw material opening device of the prior art has a high risk of worker's fatigue in the technique of using a round bar or a hammer and a high possibility of a worker's safety accident during opening work. There was a problem that caused the disruption of steel work due to.
    In addition, in a technique using a shaft with an opening protrusion, a cylinder is difficult to operate in a state in which a large amount of raw material remains, which delays opening of the raw material, and causes the connection portion 19 between the shaft 18 and the cylinder rod to fall off. Frequently, a problem occurs that causes inefficiency of the opening operation in practical use.
    The present invention has been made in order to solve the problems of the prior art described above, by reducing the fatigue of the worker while ensuring the safety, by reducing the fatigue time of the raw material by opening the raw material mechanically stayed in the hopper without operator intervention The purpose of the present invention is to provide a feeder box raw material opening device that can improve the workability of raw material input and promote the stability of steelmaking refining operations.

    The slip ring 48 mounted on the central axis 49 constituting the main opening part is fixed to the horizontal frame 61 in a plate shape so that the central axis 49 can move through the slip ring 48, and slip The upper part of the elastic body 50 mounted on the central shaft 49 on the ring 48 is mounted with a vibration transmitting body 32 having a through hole formed therein so that the central shaft 49 can move therethrough. 50 is composed of a pair of members that can be opened to both sides by the lower end is coupled to the rotating piece (30a, 30b) is installed at its end, respectively, the central shaft (49) passes through the vibration carrier (32) feeder box It opens when it rises to (10) side and conversely, when the central axis 49 falls, it is comprised so that it may be gathered and closed by the vibration transmitting body 32. FIG.
    Referring to the lifting part constituting the present invention, a striker 51 is mounted on an outer circumferential side of the disc-shaped pedestal 39 on which the motor 36 is mounted, and a central shaft 49 is provided on both sides of the pedestal 39. A pair of lifting cylinders 34 and 35 installed in parallel with each other are installed so that the cylinder rods 37 and 38 are coupled to the pedestal 39 and the cylinders 34 and 35 are fixed to the horizontal frame 61. A lifting part is achieved including a pedestal 39 on which lifting cylinders 34 and 35 and striker 51 are mounted.
    In the present invention, the auxiliary opening portion is also mounted to the lower of the feeder box 10, the horizontal frame 61 is installed by a pair of vertical frames 62 mounted to the lower feeder box 10, the vertical frame 62 of one side ) Is coupled to support the vibration carrier 32 by the elastic body 31 extending horizontally, the air breaker 33 is mounted on the other side of the vibration carrier 32, the elastic body 31, the vibration carrier 32 , The air breaker 33 constitutes the auxiliary opening.
    In the present invention, the cylinders 34 and 35 are supplied with air from the air supply source 45 through the solenoid valve 41, and the air breaker 33 also supplies air from the air supply source 45 through the solenoid valve 44. The motor 36 for rotating the swivel table 30 is electrically connected to the central control unit 43 through the motor controller 42, and the solenoid valves 41 and 44, the striker 51 and The limit switch 40 which is operated in contact is also electrically connected to the central control unit 43, and the operation panel 46 is electrically connected to the central control unit 43.
    Hereinafter, the operation of the feeder box raw material opening device of the present invention configured as described above.
    In order to open the raw material retained in the hopper, first, the solenoid valve 44 is operated to relax the air breaker 33 so that the vibration carrier 32 and the central shaft 49 can move up and down. Relax and operate the solenoid valve 41 to reduce the loads 37 and 38 of the lifting cylinders 34 and 35 so that the central shaft 49 on which the swivel 30 is mounted passes through the feeder box 10. (1) to reach the bottom.

    When the raw material falls by the rotation of the rotary pieces 30a and 30b and the load is transmitted to the rotary table 30 and the opening of the raw material is confirmed, the operation of the rotary motor 36 is stopped and the lifting cylinders 34 and 35 are stopped. When the central shaft 49 is lowered by the extending operation of the lifter 1 and is pulled out of the hopper 1 and the striker 51 mounted on the pedestal 39 touches the limit switch 40, the lowering operation of the lifting cylinders 34 and 35 is performed. This stops and the air breaker 33 operates to fix the central shaft 49 in close contact with the vibration carrier 33.
    Subsequently, the vibrator 2 of the feeder box 10 is operated to provide vibration, thereby dispensing the raw material of the feeder box.
    Such an apparatus of the present invention has no operational difficulty in opening a relatively powdered raw material, and in the case of alloy iron having a high specific gravity, it may be applied by changing the shape of the rotating table according to the shape of the raw material.
    Therefore, according to the present invention as described above, it is possible to perform the opening of the raw material mechanically by operating the operation panel without the operator's direct intervention to reduce the fatigue of the operator and to ensure safety and to improve the opening time of the raw material. Shortening can improve the productivity and reliability of steelmaking work.
