Description

本発明は、圧搾すると固まり易く硬化し易い原料を、圧搾後に小片状に裁断して排出するスクリュプレスに関するものである。   The present invention relates to a screw press that cuts and discharges, after pressing, raw materials that are easily hardened and hardened when pressed.

例えば、合成ゴムの原料などに含まれる水分を圧搾除去するためにスクリュプレスを使用すると、押し出された圧搾原料は硬化した板状のものとして排出され、このままでは後段の処理に極めて難渋する。このために、次工程で裁断機などにより板状の圧搾原料を小片に裁断する必要があるが、それだけ全体の設備が大掛りとなり、経費も嵩む欠点がある。このことを解決するために、特許文献１にはリング状の溝を通して裁断する手段が開示されている。   For example, if a screw press is used to squeeze and remove moisture contained in a raw material of synthetic rubber, the extruded raw material is discharged as a hardened plate, which makes it extremely difficult to perform subsequent processing. For this reason, it is necessary to cut the plate-shaped pressing raw material into small pieces by a cutting machine or the like in the next step, but there is a disadvantage that the entire equipment becomes large and the cost increases. In order to solve this, Patent Document 1 discloses means for cutting through a ring-shaped groove.

本発明を図示の実施例に基づいて詳細に説明する。
図１は実施例のスクリュプレスの縦断面図である。両側の基台１、２にそれぞれ軸受３、４が固定され、スクリュ軸５が軸受３及び４間に回転自在に支承されている。スクリュ軸５の左端に固定したスプロケット６を介して、図示しないチェーン、モータによりスクリュ軸５が回転可能とされている。スクリュ軸５の外周にはスクリュ羽根７が螺旋状に巻回され、更にこのスクリュ羽根７を囲むように多数の濾過孔を有する円筒状の濾過筒８が配置され、濾過筒８の外周には複数の補強環９を設けられている。 The present invention will be described in detail based on the embodiments shown in the drawings.
FIG. 1 is a longitudinal sectional view of a screw press according to an embodiment. Bearings 3 and 4 are respectively fixed to the bases 1 and 2 on both sides, and a screw shaft 5 is rotatably supported between the bearings 3 and 4. The screw shaft 5 is rotatable by a chain and a motor (not shown) through a sprocket 6 fixed to the left end of the screw shaft 5. A screw blade 7 is spirally wound around the outer periphery of the screw shaft 5, and a cylindrical filter tube 8 having a large number of filter holes is disposed so as to surround the screw blade 7. A plurality of reinforcing rings 9 are provided.

スクリュ軸５は右方の上流側から左方の下流側に向けてその径が増大するテーパ状とされ、スクリュ羽根７が巻回され、スクリュ軸５、スクリュ羽根７及び濾過筒８によって囲まれる空間が右方から左方に向けて減少している。なお、スクリュ軸５を等径とし、スクリュ羽根７のピッチを左方に向うにつれ狭くするようにしてもよい。スクリュ羽根７の外周は濾過筒８の内周にほぼ接しており、濾過筒８の上流及び下流側にはそれぞれ側板１０、１１が設けられ、スクリュ軸５はこれらの側板１０、１１を貫通している。   The screw shaft 5 is tapered so that its diameter increases from the right upstream side toward the left downstream side, the screw blade 7 is wound, and is surrounded by the screw shaft 5, the screw blade 7 and the filter cylinder 8. The space decreases from right to left. Note that the screw shaft 5 may have the same diameter, and the pitch of the screw blades 7 may be narrowed toward the left. The outer periphery of the screw blade 7 is substantially in contact with the inner periphery of the filter tube 8, and side plates 10 and 11 are provided on the upstream and downstream sides of the filter tube 8, respectively, and the screw shaft 5 passes through these side plates 10 and 11. ing.

更に、濾過筒８の右端には原料を投入するための投入ロ１２が設けられ、左端には排出口１３が設けられている。そして、濾過筒８の下方には搾液受皿１４が設けられている。   In addition, a feeding rod 12 for feeding the raw material is provided at the right end of the filter cylinder 8, and a discharge port 13 is provided at the left end. A squeezing tray 14 is provided below the filter cylinder 8.

図２にも示すように、排出側のスクリュ羽根７の後端以降のスクリュ軸５の周囲にリング部材１５が構設され、このリング部材１５の入口側の内側のスクリュ軸５との間に、例えば１２枚の第１の固定刃１６が、スクリュ軸５の軸方向に向けて図２に示すように放射状に配置され、第１の固定刃１６の刃先１６ａは上流側に向けられている。   As shown in FIG. 2, a ring member 15 is provided around the screw shaft 5 after the rear end of the screw blade 7 on the discharge side, and between the screw shaft 5 on the inner side on the inlet side of the ring member 15. For example, twelve first fixed blades 16 are arranged radially as shown in FIG. 2 in the axial direction of the screw shaft 5, and the cutting edge 16a of the first fixed blade 16 is directed upstream. .

また、第１の固定刃１６の下流に隣接したスクリュ軸５の周囲には、例えば４枚の回転刃１７が取り付けられており、これらの回転刃１７はスクリュ軸５の回転方向に対して傾斜して配置され、刃先１７ａは上流側にかつスクリュ軸５の回転方向と反対方向を向いている。なお、この回転刃１７は傾斜させずに、スクリュ軸５の円周方向に向けて配置してもよく、この場合には刃先１７ａはスクリュ軸５の回転方向と反対方向に向ければよい。   Further, for example, four rotary blades 17 are attached around the screw shaft 5 adjacent to the downstream side of the first fixed blade 16, and these rotary blades 17 are inclined with respect to the rotational direction of the screw shaft 5. The blade edge 17a is directed upstream and in the direction opposite to the direction of rotation of the screw shaft 5. In addition, you may arrange | position this rotary blade 17 toward the circumferential direction of the screw shaft 5, without making it incline, and the blade edge | tip 17a should just face in the direction opposite to the rotation direction of the screw shaft 5.

更に、回転刃１７の下流側に隣接してリング部材１５の出口側の内側に、例えば１２枚の第２の固定刃１８が設けられ、第２の固定刃１８はスクリュ軸５の円周方向に配置され、刃先１８ａは回転方向と反対方向に向けられている。なお、第１、第２の固定刃１６、１８、回転刃１７の刃先１６ａ、１８ａ、１７ａは、原料を切断し易いように鋭角のエッジ刃に加工されている。   Further, for example, twelve second fixed blades 18 are provided on the outlet side of the ring member 15 adjacent to the downstream side of the rotary blade 17, and the second fixed blades 18 are arranged in the circumferential direction of the screw shaft 5. The blade edge 18a is oriented in the direction opposite to the rotation direction. The first and second fixed blades 16 and 18 and the cutting edges 16a, 18a and 17a of the rotary blade 17 are processed into sharp edge blades so that the raw material can be easily cut.

スクリュ軸５、スクリュ羽根７を回転させながら、投入口１２から液体分を含んだ原料を投入すると、原料はスクリュ軸５、スクリュ羽根７及び濾過筒８で囲まれた空間内で、右方から左方に圧搾されながら搬送され、含有されていた液体は濾過筒８に開けた濾過孔により濾過されて搾液受皿１４に集められ、取り出される。   When a raw material containing a liquid component is introduced from the inlet 12 while rotating the screw shaft 5 and the screw blade 7, the raw material is introduced from the right in the space surrounded by the screw shaft 5, the screw blade 7 and the filter cylinder 8. The liquid contained while being squeezed to the left is filtered through a filter hole opened in the filter cylinder 8, collected in the squeeze tray 14, and taken out.

圧搾が終了した原料は、スクリュプレスの左端で排出口１３に排出されることになるが、硬化して円筒状に圧縮された原料は、その最終過程で第１の固定刃１６によって原料の移動方向に沿って帯状に切断される。更に、第１の固定刃１６で帯状に切断された原料は、回転刃１７によって幅方向つまり回転方向に切断されることになる。このとき、回転刃１７の刃先１７ａは第１の固定刃１６間から押し出されてくる原料を切断し易いように、回転方向に向けて傾斜するように設けられている。   The raw material that has been compressed is discharged to the discharge port 13 at the left end of the screw press. The raw material that has been cured and compressed into a cylindrical shape is moved by the first fixed blade 16 in the final process. It is cut into strips along the direction. Furthermore, the raw material cut into a strip shape by the first fixed blade 16 is cut in the width direction, that is, the rotation direction by the rotary blade 17. At this time, the blade edge 17a of the rotary blade 17 is provided so as to be inclined in the rotation direction so that the raw material extruded from between the first fixed blades 16 can be easily cut.

第１の固定刃１６で帯状に切断された原料は、回転刃１７の間を進み第２の固定刃１８により切断されることになるが、第１、第２の固定刃１６、１８により支持された原料を回転刃１７により切断することになり、切断が効率的になされる。このようにして、圧搾された原料は第１の固定刃１６、回転刃１７、第２の固定刃１８により小片状に裁断され、排出口１３から排出されるので、以後の処理は極めて容易となる。   The raw material cut into a strip shape by the first fixed blade 16 advances between the rotary blades 17 and is cut by the second fixed blade 18, but is supported by the first and second fixed blades 16 and 18. The cut raw material is cut by the rotary blade 17, so that the cutting is performed efficiently. In this way, the compressed raw material is cut into small pieces by the first fixed blade 16, the rotary blade 17, and the second fixed blade 18 and discharged from the discharge port 13, so that the subsequent processing is extremely easy. It becomes.

第２の固定刃１８は効果的な切断が可能なように、原料の送り速度、第１の固定刃１６の位置などを勘案して、その数、位置、傾斜角を決定すればよい。   The number, position, and inclination angle of the second fixed blade 18 may be determined in consideration of the feed rate of the raw material, the position of the first fixed blade 16 and the like so that effective cutting is possible.

また、第１の固定刃１６、回転刃１７、第２の固定刃１８は、原料に対する抵抗となって出力負荷を増大する作用もあるため、スクリュ羽根７等による原料に加わる圧力は大きくなり、圧搾効率も向上する利点もある。   In addition, the first fixed blade 16, the rotary blade 17, and the second fixed blade 18 have a function of increasing resistance against the raw material and increasing the output load, so that the pressure applied to the raw material by the screw blades 7 and the like increases. There is also an advantage of improving the compression efficiency.

なお、本発明は上述した実施例にのみ限定されるものではなく、幾多の変形が可能である。   In addition, this invention is not limited only to the Example mentioned above, Many deformation | transformation are possible.
