炉頂装入装置としてベル式のものにかわり炉内に
旋回シユートを有する形式のいわゆるベルレス式
炉頂装入装置が普及しつつある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cutgate. In place of the bell-type blast furnace top charging device, a so-called bell-less type blast furnace top charging device having a rotating chute inside the furnace is becoming popular.
この形式の炉頂装入装置は高炉の炉頂部に設け
たホツパーに原料を貯えた後、このホツパーから
垂直シユートを介して炉内の旋回シユートへ落下
させ、この旋回シユートを旋回させて原料を高炉
へ装入する装置である。 This type of furnace top charging device stores raw materials in a hopper installed at the top of the blast furnace, and then drops the raw materials from the hopper through a vertical chute into a rotating chute in the furnace, which rotates the raw materials. This is a device for charging into a blast furnace.
ところが前記ベルレス式炉頂装入装置は炉頂部
に設けられた前記ホツパーの中心軸が高炉の炉心
に対して同心ではなく偏心した位置に設置されて

で旋回シユートによつて原料を炉内に装入すると
炉内ではゆがんだ円状に装入され、高炉操業上
種々の問題が生じる。 However, in the bell-less type furnace top charging device, the central axis of the hopper provided at the top of the furnace is not concentric with the blast furnace core, but is installed at an eccentric position, so the raw material flows down inside the vertical chute. When raw materials are charged into the furnace using the rotating chute, they do not flow through the center of the vertical chute, but flow down along the inner wall on the opposite side of the hopper installation position. This causes various problems in blast furnace operation.

る。 The present invention has been made to solve such problems, and it is an object of the present invention to provide a device that allows the raw material to always pass through the center of the vertical chute when it flows down the vertical chute. The gist of this is that in the middle of a vertical chute,
In the cut gate that adjusts the flow rate of particulate matter flowing down in the chute, cut gates that divide the flow path cross section of the vertical chute into two and open and close in opposite directions are installed in multiple stages so that the opening and closing directions are orthogonal to each other. It is a cut gate featuring the following.

る。 As shown in FIGS. 1 and 2, the present invention provides shafts 4 and 5 on both outer surfaces of a vertical chute 3 located between an upper inlet flow path 1 and a lower outlet flow path 2. A cut gate 6 is provided on the outer surface of the vertical chute 3 which is above the shafts 4 and 5 and perpendicular to the installation position of the shafts 4 and 5. Shafts 7 and 8 are installed, and cut gates 9 are installed on these shafts 7 and 8.
カツトゲート６及び９は以下のような構造とす

ピン１７により同時に軸支されている。 That is, the cut gate 6 consists of a pair of fan-shaped side plates 6A, 6B and bottom plates 6C and 6D, which are supported on shafts 4 and 5, and the bottom plates 6C and 6D form part of a spherical surface.
When the side plates 6A and 6B rotate to the positions shown by two-dot chain lines 10A and 10B, the spherical surfaces are made to be the same as the locus of movement of the bottom plates 6C and 6D. Arm 11A is attached to the side plate 6A, and arm 1 is attached to the side plate 6B.
1B is fixed, an arm 13 is rotatably provided at the end of the arm 11A via a pin 12, and an arm 15 is rotatably provided at the end of the arm 11B via a pin 14. and said arm 13
and 15 are simultaneously pivotally supported by a pin 17 in a rod 16A of a drive cylinder 16 fixed near the outer side of the vertical chute 3.

を２分割した位置（閉止位置）から互いに相反す
る方向に流路を開くように開閉が可能である。 That is, the cut gate 6 uses the drive cylinder 16 as a driving source to drive the shafts 4 and 5 and the arms 11A and 1.
1B, pins 12, 14, arms 13, 15, pin 17, and a rod 16A that moves back and forth.The link mechanism consists of a rod 16A that moves back and forth to allow the flow to flow in opposite directions from a position where the cross section of the vertical chute 3 is divided into two (closed position). It can be opened and closed to open the road.
一方、カツトゲート９は前記カツトゲート６の
内側に設けられており、その開閉方向がカツトゲ
ート６の開閉方向と直交するように、かつ開閉が
前記カツトゲート６に干渉されずに行なえるよう
に設置されている。 On the other hand, the cut gate 9 is provided inside the cut gate 6, and is installed so that its opening/closing direction is perpendicular to the opening/closing direction of the cut gate 6 and can be opened and closed without being interfered with by the cut gate 6. .

られている。 That is, the cut gate 9 has side plates 9A and 9B rotatably installed by shafts 7 and 8, and bottom plates 9C and 9D.
A similar type of cut gate 6 is provided so that the cut gate 6 slides on the upper part of the bottom plates 6C and 6D of the cut gate 6, or rotates above the bottom plates 6C and 6D without sliding.
図中、１７Ａは駆動シリンダーのロツド、１
８，１９はアームを示す。 In the figure, 17A is the drive cylinder rod, 1
8 and 19 indicate arms.
このカツトゲート９は、前記カツトゲート６と
同様にその底板９Ｃ，９Ｄを球面の一部をなす形
状としたからカツトゲート６の開閉に干渉されず
に開閉が可能である。 This cut gate 9 can be opened and closed without interfering with the opening and closing of the cut gate 6 because its bottom plates 9C and 9D are shaped to form part of a spherical surface like the cut gate 6.
従つて、駆動シリンダー１６によりロツド１６
Ａを前進させると共に90度方向を異にして固設し

ート３の中央部に流体の流路を形成する。 Therefore, the rod 16 is driven by the drive cylinder 16.
When the rod 17A is moved forward by driving the driving cylinders fixed at different angles at 90 degrees, both the cut gates 6 and 9 open to form a fluid flow path in the center of the vertical chute 3.
カツトゲート６，９の開度はロツド１６Ａ，１
７Ａの移動量により調整することができるから、
この移動量を垂直シユート３内を落下する原料の

成される原料の流路を示す平面図である。 The opening degree of cut gates 6, 9 is rod 16A, 1
Since it can be adjusted by the amount of movement of 7A,
The amount of this movement is simultaneously controlled by the amount of raw material falling within the vertical chute 3. FIG. 3 is a plan view showing the raw material flow path formed in the vertical chute 3 when the cut gates 6 and 9 are both opened.
第３図に示すように、本発明によれば垂直シユ

原料に偏流がなく、従つて原料は旋回シユートの
中央部に落下するので旋回シユートにより炉内へ
装入される原料は旋回シユートの傾動角度が一定
である限り炉内では円状に落下する。 As shown in FIG. 3, according to the present invention, a fluid flow path 20 can always be formed in the center of the vertical chute, and therefore, the raw material can Even if the raw material flows down along the side wall of the vertical chute, it is corrected by the cut gate of the present invention so that it always flows down the center of the vertical chute, and there is no drift in the raw material in the outlet flow path, so the raw material falls into the center of the rotating chute. Therefore, the raw material charged into the furnace by the rotating chute falls in a circular manner within the furnace as long as the tilt angle of the rotating chute is constant.
また、スパイラル状に原料を装入する場合であ
つても旋回シユート上へ落下する原料の落下位置
を固定できるから炉内への原料装入を行う上で有
効である。 Further, even when the raw material is charged in a spiral manner, the falling position of the raw material falling onto the rotating chute can be fixed, which is effective in charging the raw material into the furnace.
なお、本発明に係る垂直シユートを高炉炉頂装
入装置の垂直シユートとして説明したが、高炉炉
頂装入装置に限らず粉、粒、塊状の物質を流下さ
せる垂直シユートに広く応用できるものである。 Although the vertical chute according to the present invention has been described as a vertical chute for a blast furnace top charging device, it can be widely applied not only to a blast furnace top charging device but also to a vertical chute for flowing down powder, grains, or lump-like materials. be.
以上述べたように本発明は構造が簡単であるた
め、取付スペースが小さくて済み、修理整備も容
易であるという利点がある。 As described above, since the present invention has a simple structure, it has the advantage that it requires a small installation space and is easy to repair.
