We have developed an oscillating type rough-splitting machine that can efficiently rough-split or deform large chunks of furnace slag larger than m. (Special application 1982-23
No. 20) The oscillating rough splitting machine is explained with reference to FIGS. 1 and 2. 1 is a fixed rough splitting plate fixed perpendicularly to the left side wall of the casing 2, and 3 is a fixed rough splitting plate facing opposite to the fixed rough splitting plate. The swinging rough dividing plate 3 is fixed to a jaw 5 that swings back and forth while moving up and down using an eccentric shaft 4 as a fulcrum. The eccentric shaft 4 has its shaft end directly connected to the rotating shaft 6, and is integrated with the rotating shaft 6. A V-boo 97 is fixedly installed on the rotating shaft 6, and this V-pulley 7 is connected to the V-pulley 7 on the output shaft of an electric motor (not shown). A V-belt 8 is installed between them. Reference numeral 9 denotes a rough dividing chamber formed between the fixed rough dividing plate 1 and the swinging rough dividing plate 3.

面の山11の数が4つになされている。The opposing surface shapes of the fixed rough dividing plate 1 and the swinging rough dividing plate 3 are as follows:
The rough-splitting-like entrance, that is, the entrance 11 at the upper end of the rough-splitting chamber 9 has a wavy shape in which peaks 11 and valleys 12 face each other in the radial direction. The number of ridges 11 on the surface of one coarsely divided plate is three, and the number of ridges 11 on the surface of the other coarsely divided plate is four.

The oscillating coarse plate 3 is made to be 175 to 2/5 of the dimension between these, and the oscillating coarse plate 3 can maintain a constant compressive force, and has a structure on the back side of the oscillating coarse plate 3. A hydraulic mechanism 14 is provided which can be retracted in the event of an overcoming reaction force.

式で繰返し圧縮力が加えられ、油圧機構14の油圧シリ
ンダー15には圧力が発生する。In the oscillating coarse cracker configured as above, the lumpy furnace slag S, which is 300 to 500 mm or more and has an iron content of 5o to 60% or more, which is input from the entrance 10 of the coarse cracking chamber 9, is oscillated. The moving oscillating rough dividing plate 3 is pressed against the υ fixed rough dividing plate 1, and compressive force is applied repeatedly in the form of three-point bending as shown in Fig. 2 by being sandwiched between the peaks 11 of the corrugated surfaces of both, and the hydraulic pressure is applied. Pressure is generated in the hydraulic cylinder 15 of the mechanism 14.

し、再び揺動粗割板3によシ圧縮力を受けて粗割され、
これが数回繰返されて、粗割室9の出口13の通常の間
隙W′以下の寸法となると、出口13より排出落下する
。If the pressure of this hydraulic cylinder 15 is less than the holding force of the hydraulic system and the lumpy slag S is roughly split, when the oscillating rough splitting plate 3 moves away from the fixed rough splitting plate 1 side, the roughly split slag will be affected by gravity. It descends and is roughly divided again by the oscillating coarse dividing plate 3 under compressive force.
This is repeated several times, and when the size becomes smaller than the normal gap W' of the outlet 13 of the rough-cutting chamber 9, the particles are discharged from the outlet 13 and fall.
一方、塊状炉滓Sの圧縮時、揺動粗割板3の圧力が油圧

で塊状炉滓Sを圧縮したiま揺動ストローク分だけ揺動
粗割板3が後退し、出口13の間隙Wが拡がる。On the other hand, when the pressure of the rocking rough-splitting plate 3 exceeds the holding force of the hydraulic system during compression of the lumpy slag S, in other words, if a reaction force that overcomes the compression force of the rocking rough-splitting plate 3 is generated in the lumpy slag S. , the pressure oil in the hydraulic cylinder 15 is returned to the hydraulic unit, and the rocking coarse plate 3 retreats by the rocking stroke that compresses the lumpy slag S by the holding force of the hydraulic system, and the gap W of the outlet 13 is reduced. expands.
従って、塊状炉滓Sは自重によシ落下し、再び揺動粗割
板3の圧縮力を受けて少量の変形成いは部分的な剥離が
なされる。こうして粗割できない炉滓は、徐々に変形成
いは部分的な鉄分の少ない鉱滓の剥離により、出口13
を排出落下する。Therefore, the lumpy slag S falls down under its own weight, and is again subjected to the compressive force of the rocking coarse plate 3, causing a small amount of deformation or partial peeling. In this way, the furnace slag that cannot be roughly divided is gradually deformed or partially peeled off from the slag with low iron content.
The discharge will fall.

~60% of the lumpy furnace slag S is continuously and efficiently coarsely cracked or deformed to a size of 300 to 500 W+ or less,
Moreover, the iron content is increased to 90% or more.

幅に減少するという問題点があった。By the way, in the operation of the above-mentioned oscillating coarse-splitting machine, the lumpy furnace slag S that has been reliably bitten into the rough-splitting chamber 9 is coarsely divided as described above, or the oscillating coarse-splitting plate is rotated by the oscillating stroke. 3 undergoes deformation as it retreats, but depending on the shape and properties of the lumpy furnace slag S, it may not be reliably bitten into the rough-splitting chamber 9 and may escape upward within the rough-splitting chamber 9. Such a lumpy slag S
Even if the oscillating rough dividing plate 3 is oscillated as it is, the compressive force is not applied effectively and the compressive force remains in the coarse dividing chamber 9 for a long time. In such cases, stop operation and
Either lift the lumpy slag S upward and discharge it, or use the hydraulic mechanism 1.
4, the exit size of the rough-splitting chamber 9 can be greatly expanded to discharge the raw material downward, which has the problem that the operating time of the swing-type coarse-splitting machine is significantly reduced.

The purpose is to provide the following.

を特徴とするものである。(Structure of the Invention) The operating method of the oscillating rough-splitting machine of the present invention is such that while applying a constant compressive force to the material to be coarse-split and performing rough-splitting, a reaction force that overcomes the compressive force is not generated. Even if the dimension between the opposing roughing plates at the outlet of the lower end of the roughing chamber is set to 1/10 to 1/10 of the initial setting value,
It is characterized by expanding and contracting in stages at a rate of 15.

粗割機の運転を一旦止めざるを得ないものである。In the operating method of the oscillating rough splitting machine of the present invention, the reason why the outlet dimension of the lower end of the rough splitting draft is gradually expanded or reduced at a ratio of 1710 to 115 of the initial setting value is as follows. This is to change the contact position of the rough splitting plate as the lumpy slag introduced into the splitting chamber falls downward step by step, and to roughly split or deform the lumpy slag. There is little change in the contact position of the plate, and the range of the smooth sliding surface is simply expanded! 5. If the value exceeds 115, the contact position of the coarse plate will change, but since it is not possible to increase the number of changes, find a position where the lumpy furnace slag will not be caught upwards, but will be firmly caught. ``It takes too long to complete the process, and as a result, we have no choice but to temporarily stop the operation of the coarse splitter halfway through the process.

異なる位置で接触し始めるものである。Set the exit dimension of the lower end of the rough split draft to 1/1° to 11° of the initial setting value.
By expanding or contracting in stages at a rate of 5, the amount of change in the outlet dimension is approximately the same as the stroke amount of the oscillating coarse plate, and when viewed from the coarse plate side, the block furnace The slag begins to come into contact at a completely different location.

When 60% or more of the lumpy furnace slag S is introduced, it is pressed against the fixed coarse dividing plate 1 by the oscillating coarse dividing plate 3, and is sandwiched between the peaks 11 of the corrugated surfaces of both, as shown in Fig. 2.
