関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a compression molding apparatus equipped with a mixer used, for example, in producing forcibly carburized reduced iron briquettes. That is, like when manufacturing carburized reduced iron briquettes, a carburizing material such as coke powder and high temperature reduced iron particles are mixed in advance, and then this mixture is compression-molded using a roll preceller or the like. Regarding equipment.
このような圧縮成形装置においては、成形能率を上げる
ために混合物を圧縮成形する前に、混合物の密度を高め
ておく必要があシ、スクリューフィーダ使用による予備
加圧が行われている。しかし、スクリューフィーダのみ
では異材料（例えば還元鉄粒子とコークス粉）の混合が
充分性われない問題がある。In such a compression molding apparatus, in order to increase molding efficiency, it is necessary to increase the density of the mixture before compression molding the mixture, and preliminary pressurization is performed using a screw feeder. However, there is a problem in that the screw feeder alone does not allow sufficient mixing of different materials (for example, reduced iron particles and coke powder).
そこで、本発明者らは垂直のスクリュー軸に対して斜上

に、この自由流動面を攪拌するのが最も良好な混合が得
られることを見出し、本発明に到達したものである。Therefore, the present inventors discovered that the flow of the main raw material (high-temperature reduced iron particles in the case of carburized reduced iron briquettes) fed obliquely upward to the vertical screw shaft, and that this flow When changing the direction of flow, we noticed that there was a so-called free-flowing surface with active flow even at the outermost surface of the flow, and we noticed that powder particles (carburized reduced iron briquettes) were trying to mix into this free-flowing surface. In this case, we tried adding coke powder). As a result, it was discovered that the best mixing could be achieved by supplying the powder particles to be mixed upward to the free-flowing surface of the main raw materials and stirring this free-flowing surface. It has been reached.

る混合機能を有する圧縮成形装置に関するものである。That is, the present invention provides an apparatus for compression molding a powder or granular material after pre-pressurizing it by a screw feeder, in which the powder or granular material, which is the main constituent material of a molded product, is transferred from an obliquely upward direction to a screw shaft perpendicular to a screw chamber. A second powder and granular material to be mixed is added above the free-flowing surface formed by the powder and granular material in the chamber, and the free-flowing surface is forcibly stirred by a stirring means. The present invention relates to a compression molding apparatus having a mixing function characterized by the following.
以下、本発明装置の詳細について図面により説明する。Hereinafter, details of the device of the present invention will be explained with reference to the drawings.
第１図は本発明装置の一実施態様例を示すもので、加炭
した還元鉄ブリケットの製造に使用する場合を例にして
説明する。FIG. 1 shows an embodiment of the apparatus of the present invention, and will be described using the apparatus for producing carburized reduced iron briquettes as an example.

ぞれ示す。In Fig. 1, 1 is a hopper for storing reduced iron particles S, 2 is a chute for supplying reduced iron particles S to a screw chamber 3, 4 is a screw, 5 is a screw shaft, and 6 is a screw shaft. A driving motor, 7 a region for pre-pressing the mixture, 8 a roll type briquette, 9 a briquette hole mold, and 10 a compression-molded finished briquette.

添加シュート１２を施ける。このコークス粉はシュート
１２上部のコークス粉ホッパー１３から定量供給機１４
を介して供給添加されるようになっている。In a roll briquette with such a configuration, a free-flow surface 11 is created at the location where the reduced iron particles S enter the screen chamber B via the chute 2. This free flowing surface 11
A coke powder addition chute 12 is provided so that coke powder can be added from above. This coke powder is fed from the coke powder hopper 13 on the upper part of the chute 12 to the quantitative feeder 14.
It is designed to be added through the feed.

１１での斜下方への一次元的な流れを乱し、これによシ
自由流動面１１上に添加されたコークス粉を主原料の流
れの中へ均一に混合させることができる。By the way, the coke powder added onto the free-flowing surface 11 is swept diagonally downward due to the violent flow of raw material particles diagonally downward (to the right in the drawing) on the free-flowing surface 11, and is segregated on the right side of the screw chamber 5. However, since the rain particles will not be mixed sufficiently, it is necessary to stir the free-flowing surface 11 with the stirring blade 15 attached to the screw shaft 5. The original flow is disturbed so that the coke powder added on the free-flowing surface 11 can be mixed uniformly into the main raw material flow.
なお、自由流動面１１を攪拌するための攪拌翼１５とし

用いてもよい。The stirring blades 15 for stirring the free-flowing surface 11 may be, for example, two-blade or four-blade blades as shown in FIGS. 2 and 3, which are sectional views taken along line 1-1 in FIG. Alternatively, although not shown, a screw-shaped stirring blade may be used.
以上詳述したように、本発明装置においては均一な混合
状態の混合物圧縮成形品を得ることができるので、工業
上極めて有利である。As described above in detail, the apparatus of the present invention is extremely advantageous industrially since it is possible to obtain a compression-molded mixture in a uniformly mixed state.
