【考案の詳細な説明】 〔産業上の利用分野〕 本考案は、製銑用焼結試験鍋に粒粉体の焼結原料を分散
させながら充填するのに用いる焼結試験用原料分散充填
装置に関する。[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a sintering test raw material dispersion and filling device used for filling a sintering test pot for pig iron making while dispersing a sintering raw material of granular powder. Regarding
従来、円筒状で堅型の50kg用焼結試験鍋に焼結原料を充
填する場合、中型シャベルにて一度に約600gの焼結原料
を掬い、人手によって少量ずつ分散させながら所定の層
高に充填する方法が採用されてきた。Conventionally, when filling a cylindrical and rigid 50 kg sintering test pot with sintering raw material, a medium-sized shovel scoops approximately 600 g of the sintering raw material at a time and manually distributes the sintering raw material little by little to reach a predetermined layer height. The method of filling has been adopted.
その理由として、人手による装入、即ち手装入によれば
充填層内の粒度偏析が小さく、密度分布も均一化され易
いなどの利点がある。確認したところによれば、シャベ
ルにて掬った焼結原料を一度に試験鍋へ装入し、これを
繰り返しながら充填するよりも少量ずつ分散させながら
試験鍋を充填する方が焼結原料の充填構造は再現性に富
み、試験精度は高くなる。The reason for this is that the manual charging, that is, the manual charging has the advantage that the particle size segregation in the packed bed is small and the density distribution is easily uniformized. According to what we confirmed, it is better to fill the test pot by dispersing it little by little than charging it by shoveling the sintering raw material at once into the test pot and then filling it repeatedly. The structure is highly reproducible and the test accuracy is high.
更に、焼結試験鍋における壁効果を抑制する一手段とし
て周壁に断熱材を内張りする場合には、断熱材を崩した
り乱したりしないためにも手装入がよいとされてきた。Further, when a heat insulating material is lined on the peripheral wall as one means for suppressing the wall effect in the sintering test pot, it has been said that manual insertion is good in order not to collapse or disturb the heat insulating material.
本考案者らは焼結試験鍋に焼結原料を分散させながら充
填する装置を実願昭63−151493号（実開平２−75137号
公報）として出願した。The present inventors applied for a device for filling the sintering test pot while dispersing the sintering raw material as Japanese Patent Application No. 63-151493 (Japanese Utility Model Publication No. 2-75137).
この装置は試験鍋に充填する焼結原料が例えば10kg以下
と少ない場合に有効である。This device is effective when the sintering raw material filled in the test pot is small, for example, 10 kg or less.
しかしながら、試験鍋に充填する焼結原料が20kg以上に
多くなると、上記考案の充填装置を単に大型化しただけ
では焼結原料の分散効果は不十分であり、かつ装置重量
と焼結原料の重量を考えるとハンドリングが困難なの
で、依然として手装入による充填を行わざるを得なかっ
た。However, when the amount of sintering raw material filled in the test pot exceeds 20 kg, the effect of dispersing the sintering raw material is not sufficient by simply enlarging the filling device of the above device, and the weight of the device and the weight of the sintering raw material are not sufficient. Considering the above, handling was difficult, so I had no choice but to fill by manual insertion.
しかしながら、人手にて中型シャベルを操作しつつ焼結
原料を試験鍋に充填する従来法の繰り返し精度を充填密
度について調査したところ、そのバラツキはかなり大き
く、再現性に乏しいものであることが判明した。However, when we investigated the repeatability of the conventional method of filling the sintering raw material into the test pot while manually operating the medium-sized shovel for the packing density, it was found that the variation was quite large and the reproducibility was poor. .
従来法にて充填層内の粒度分布や充填密度の再現性を高
めるには豊富な経験と勘が要求され、熟練者といえど
も、少量ずつ試験鍋へ焼結原料を充填するには多大の手
間を要する。In order to improve the reproducibility of the particle size distribution and packing density in the packed bed by the conventional method, abundant experience and intuition are required, and even a skilled person needs a lot to fill the test pan with the sintering raw material little by little. It takes time.
50kg用焼結試験鍋では原料充填に約24分を要し、その
間、焼結原料の造粒時に添加した水分はかなり蒸発す

は焼結試験における問題点の一つである。さらに、中型
シャベルを繰り返し操作する作業は煩わしく、長期に亘
って続けると手首を傷めてしまうことになる。It takes about 24 minutes to fill the raw material in the 50 kg sintering test pot, and the water added during the granulation of the sintering raw material evaporates considerably during that time. Especially in the summer, the sintering raw material is easy to dry. Fluctuation of added water is one of the problems in the sintering test. Further, the work of repeatedly operating the medium-sized shovel is troublesome, and if it is continued for a long time, the wrist will be damaged.
本考案は、焼結試験鍋充填時において、擬似粒子化され

る。The present invention provides an apparatus capable of suppressing the particle size segregation of a sintering raw material that has been made into pseudo-particles, improving the reproducibility of the filling structure, and performing rapid filling when filling the sintering test pot.

制御バー６を予め挿入しておく。The present invention is characterized in that an outflow pipe 2 is detachably arranged at a lower end of a hopper 1 and a dispersion device 4 having a bar-shaped disperser 3 therein is arranged immediately below the hopper 1 for integral construction. It is a raw material dispersion and filling device. As shown in FIG. 1, a hoist has been conventionally used to set the sintering test pot 11 of about 120 kg in the center of the wind box 15. The hoist for moving the test pot is convenient for charging the hopper 1 with the sintering raw material, hoisting it to an appropriate height, and dropping it from directly above the sintering test pot 11 to disperse it. In particular, the hopper 1 that can be moved up and down is optimal because an appropriate head is required to disperse the sintering raw material. The hopper 1 is provided with a plurality of protrusions 5 on the inner wall slope thereof, a discharge control bar 6 which can be inserted and pulled out below the protrusions 5, a damper 7 below the discharge control bar 6, and a joint pipe 9 at the lower end of the orifice 8. It was done. The projecting portion 5 is effective for alleviating the force of the sintering raw material flowing along the slope of the inner wall of the hopper 1 and preventing hanging from the shelf. If the shelves are suspended, a discharge control bar 6 that can move in and out is provided in order to easily cancel the suspension. Further, in order to make the flow of the sintering raw material in the outflow pipe 2 smooth, the discharge control bar 6 is inserted in advance so as to slightly reduce the discharge amount from the hopper 1.

焼結原料が通り抜ける空間を設けている。The outflow pipe 2 is provided so that the sintering raw material flows out smoothly from the hopper 1, the orifice 8 has the same diameter, and is attached to the lower end of the hopper 1 through the joint pipe 9 only when the sintering raw material is filled. To do. The disperser 4 is provided with an introduction pipe 10 for guiding the outflow pipe 2 in the center, a flange 13 for supporting the bar-shaped disperser 3 at the inner lower end of the introduction pipe 10, and a sintering test pot 11 at the lower part thereof. A set frame 12 that fits at the upper end of the set frame 12 is provided, and a dispersion control tube 14 is provided at the lower inside of the set frame 12. Further, in the bar-shaped disperser 3, a plurality of bars are radially fixed inside the ring-shaped frame, and only the periphery of the central portion is cut out to provide a space through which the sintering raw material passes.

Next, the dispersion device 4 in which the bar-shaped disperser 3 is set
Is attached to the upper end of the sintering test pot 11. Then hopper 1
Is slightly lifted and the outflow pipe 2 is fitted and set in the joint pipe 9 at the lower end. Lift the hopper 1 higher with a hoist,
Gently move it just above the sintering test pot 11 set in the center of the wind box 15.

流れ出ることになる。If the cores of the outflow pipe 2 and the introduction pipe 10 are aligned, the hopper 1 is gently lowered. Since the outer diameter of the outflow pipe 2 is made slightly smaller than the inner diameter of the introduction pipe 10, the outflow pipe 2 sinks inside the introduction pipe 10 as the hopper 1 descends. The tip of the outflow pipe 2 is the introduction pipe
When it reaches about 1/2 of 10, the descent of hopper 1 is stopped and the setting is completed. Next, open the damper 7,
The sintering raw materials charged in the hopper 1 are sequentially discharged and dropped onto the bar-shaped disperser 3. Since the bar-shaped disperser 3 is provided with an appropriate space between the bars, the sintering raw material in contact with the bars is repelled and diffused downward. The diffusion of the sintering raw material to be diffused is regulated by the dispersion control cylinder 14, and the sintering test pot 11 is continuously filled while being dispersed without damaging the heat insulating material 16 lined on the peripheral wall of the sintering test pot 11. . When the sintering raw material is automatically and continuously discharged from the hopper 1, the discharge control bar 6 is put in and taken out,
When the inner wall of the hopper 1 is shocked several times at its tip, all the sintering raw material remaining in the hopper 1 is discharged. Further, by inserting the discharge control bar 6, the cross sectional space at the position of the discharge control bar 6 becomes smaller than the cross sectional space of the outflow pipe 2, so that the sintering raw material flows out more smoothly.
尚、流出管２は焼結原料の流れまで確認できるよう透明
管であることが望ましい。The outflow pipe 2 is preferably a transparent pipe so that the flow of the sintering raw material can be confirmed.
仮に、焼結原料の流れが停止した場合は、排出制御バー
６を少し引き出し、その先端をホッパー１の内壁に突き
当てる操作を行えば、焼結原料の流れは直ちに良好とな
る。If the flow of the sintering raw material is stopped, if the discharge control bar 6 is pulled out a little and the tip of the discharge control bar 6 is abutted against the inner wall of the hopper 1, the flow of the sintering raw material immediately becomes good.
突起部５は、ホッパー１の焼結原料が斜面に沿って降下
する力を弱め、排出制御バー６近傍での高密度化による
棚吊りを防止する作用をなす。The projecting portion 5 weakens the force of the sintering raw material of the hopper 1 that descends along the slope, and has the function of preventing hanging from the shelf due to the high density in the vicinity of the discharge control bar 6.

確認テストの結果を表に示す。Further, as shown in FIG. 6, the disperser 4 has a bar disperser 3 mounted in the center thereof, and an introduction pipe 10 is provided on the upper part in order to align the core wire with the hopper 1. Since the inlet pipe 10 guides the lower end of the outflow pipe 2, its inner diameter is 131.5 m /
m, the height is 110m / m, and it has a cylindrical shape,
As shown in FIGS. 6 and 6, a flange 13 having a width of 1.5 m / m is provided on the inner periphery to support the bar-shaped disperser 3. Introductory pipe 10
Was fixed in the center of the set frame 12, and a dispersion control tube 14 having an inner diameter of 230 m / m and a length of 150 m / m was provided in the lower part of the set frame 12. In this embodiment, the arrangement of the bars in the bar-shaped disperser 3 is devised for the purpose of uniformly dispersing the sintering raw material, and the seventh structure is adopted as a disperser suitable for filling the sintering test pot 11 while uniformly dispersing. A uniform dispersion type bar-shaped disperser 19 shown in the figure was used. The uniform dispersion type bar-shaped disperser 19 has an outer diameter of the outer frame ring of 131.0 m /
m, the inner diameter was 127.0 m / m, and the height was 10.0 m / m. The small ring 20 fixed on the inner side is a bar-shaped ring having an outer diameter of 41.0 m / m and an inner diameter of 25.0 m / m, and the four bars that support this are fixed on the outer frame ring on four sides. 4 bars have a diameter of 7.0m
/ m. In addition, a short intermediate bar 21 provided in the middle of the four bars supporting the small ring 20 has a diameter of 7.0 m / m and a length of four.
As shown in FIG. 8, one end is fixed to the inner side of the outer frame ring and the other end is inclined downward by about 30 degrees as shown in FIG.
The upper surface of the outer frame ring is inclined inward by about 20 degrees so that fine particles in the sintering raw material do not accumulate. When the uniform dispersion type bar-shaped disperser 19 having such a structure is dropped into the introduction pipe 10 and set, and the sintering raw material charged in the hopper 1 is cut out, the sintering raw material is the uniform dispersion-type bar-shaped disperser 19 50 kg of the sintering raw material is filled in the sintering test pot 11 in 12 to 13 seconds while being dispersed by being scattered by each bar and being dispersed evenly by the dispersion control cylinder 14. If the prescribed layer height cannot be reached with 50 kg of sintering raw material, the entire sintering raw material filling device is released, the sintering raw material of the basic weight is added by hand, and the surface layer is lightly leveled for firing. The filling of the test pot 11 is completed. The results of the accuracy confirmation test of the 50 kg sintering pot test in this example using the uniform dispersion type bar-shaped disperser 19 of FIG. 7 are shown in the table.

認した。Second Example FIG. 9 shows a low-in-periphery bar-shaped disperser 22 in a circumferential height used when a packing layer is formed on the circumferential wall portion of the sintering test pot 11 with a slightly higher height. This is used as a main part of the dispersion device 4, and the outer diameter of the outer frame ring is 131.0 m / m and the inner diameter is 127.0 m.
/ m and its height was 10.0 m / m. Although the outer frame ring has the same size as that of the first embodiment, the arrangement of the bars on the inner side is different. That is, a diameter of 8.0 m / m fixed on all four sides of the outer frame ring and a diameter of 7.0 m to the left and right of the center bar tip with a length of 46 m / m.
A downward tilting bar of m / m and length of 27.0 m / m is fixed in the shape of an arrow as shown in Fig. 10.The opening with the center bar is 20 degrees and the angle with the center bar is 27 degrees. And An intermediate bar 24 having a diameter of 7.0 m / m and a length of 25.0 m / m is provided in the middle of the arrow-shaped bar 23 provided from four sides with its tip facing upward as shown in FIG.
It was fixed at 20 degrees around the inner circumference of the outer frame ring. By arranging the bars in this way, a space of 21.0 m / m in length and width is formed in the central portion, and a space necessary for the sintering raw material to pass is also formed between the bars. Since the structure of the bar is different from that of the first embodiment, the sintering raw material flowing from the hopper 1 is largely repelled by the low-in-circumferential-high bar-shaped disperser 22 of the present invention, and the dispersion is expanded. As a result, the amount of the sintering raw material that drops by touching the dispersion control cylinder 14 increases slightly, and it becomes possible to form a somewhat higher filling layer than the inner wall of the sintering test pot 11. This was also confirmed using a transparent tube of the same size as the sintering test pot 11.

It was not much different from the result of the example. Especially, there is no big difference in packing density, sintering time and product yield.
It shows that there is no big difference in the filling structure, and the practicality of the present invention is extremely high.
