本発明は炭素材料製造装置、特に、加熱時に流動化する
粘結材、例えば、ピッチ等を含む原料を加熱下で遠心力
により加圧することによって成形ならびに焼成を同時に
達成し、しかも、その炭素材料を直接角柱状または円柱
状に焼成かつ成形できる炭素材料製造装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a carbon material manufacturing apparatus, in particular, to simultaneously achieve molding and firing by pressurizing a raw material containing a caking agent, such as pitch, which becomes fluid when heated, by centrifugal force under heating. Moreover, the present invention relates to a carbon material manufacturing apparatus that can directly fire and shape the carbon material into a prismatic or cylindrical shape.
従来、最も一般的に炭素材料を製造する場合は、コーク
スの如き骨材とピッチの如き粘結材は原料とし、これら
原料を１４０〜１５０℃で加熱混捏してから、プレス等
で加圧成形し、その後に、この成形体を例えば焼成炉内
で数日ないし１ケ月の長期にわたって８００〜１０００
℃程度まで昇温させつつ焼成して製造している。Conventionally, most commonly, when manufacturing carbon materials, aggregates such as coke and caking agents such as pitch are used as raw materials, and these raw materials are heated and kneaded at 140 to 150°C, and then pressure-formed using a press or the like. After that, this molded body is heated for a long period of 800 to 1000, for example, in a firing furnace for several days to one month.
It is manufactured by firing while raising the temperature to about ℃.
しかしながら、このように製造する場合は、成形工程と
焼成工程とがそれぞれ個別かつ単独に行なわれ、焼成工
程が非常に長時間にわたり、このような長期の焼成は生
産性の上で問題が多い。However, when manufacturing in this way, the molding step and the firing step are performed separately and independently, and the firing step takes a very long time, and such long-term firing poses many problems in terms of productivity.
また、焼成時には粘結材の一部が気体になって飛散して
骨材と粘結材とが分離するほか、この粘結材飛散部分が
孔隙になって残る。Further, during firing, a part of the caking agent becomes gas and scatters, and the aggregate and the caking agent are separated, and the parts where the caking agent is scattered remain as pores.
この焼成時における粘結材飛散に基づく欠陥を緩和する
ために、焼成は上記の如く長期間にわたり徐々に昇温さ
せて行なって気体をゆっくりと飛散させているが、この
ように焼成しても仲々緻密な構造の炭素材料は得られな
く、通常の人造黒鉛はある程度の通気性を持っているも
のである。In order to alleviate the defects caused by the scattering of the binder during firing, firing is carried out by gradually raising the temperature over a long period of time as described above, so that the gas is slowly scattered. A carbon material with a relatively dense structure cannot be obtained, and ordinary artificial graphite has a certain degree of air permeability.
これに対し、原料を回転胴に投入し、この回転胴の周囲
から加熱して、原料を加熱しつつ遠心力によって圧縮し
つつ成型する装置も提案されている。On the other hand, an apparatus has also been proposed in which the raw material is charged into a rotary cylinder, heated from around the rotary cylinder, and molded while heating the raw material and compressing it by centrifugal force.
しかし、この装置は緻密構造の材料が製造できるが、そ
の材料は円筒状のもののみに限られ、角柱状、ブロック
状、レンガ状や、更に円柱状のものが製造できない。However, although this device can produce materials with a dense structure, it is limited to cylindrical materials, and cannot produce prismatic, block-shaped, brick-shaped, or even cylindrical materials.
すなわち、第１図には通常耐熱鋼等から成る回転胴１が
示され、その周囲は加熱炉体２によって包囲されて、回
転胴１内の原料が十分に加熱される。That is, FIG. 1 shows a rotary shell 1 usually made of heat-resistant steel or the like, which is surrounded by a heating furnace body 2 so that the raw material within the rotary shell 1 is sufficiently heated.
加熱炉体２は通常内容器２ａ、外容器２ｂ、断熱材２ｃ
およびヒータ（図示せず）から構成され、加熱炉体２の
略々中心部に回転軸３を貫通させ、回転軸３の先端３ａ

更に、回転軸３の後端３ｂは冷却オイルシール６を介し
てモータ５によって回転されている。The heating furnace body 2 usually includes an inner container 2a, an outer container 2b, and a heat insulating material 2c.
and a heater (not shown), with a rotating shaft 3 passing through the approximate center of the heating furnace body 2, and a tip 3a of the rotating shaft 3.
The rotary trunk bottom plate is supported via a stopper 4 attached to the
Further, the rear end 3b of the rotating shaft 3 is rotated by a motor 5 via a cooling oil seal 6.
（なお、符号７は炉蓋、８は原料の投入管、９は雰囲気
ガス導入口、１０は排ガス管を示す。(Note that 7 is a furnace lid, 8 is a raw material input pipe, 9 is an atmospheric gas inlet, and 10 is an exhaust gas pipe.
）従って、原料は遠心力によって加圧されるが、原料は
回転胴内壁面に付着しつつ成形されるものは円筒状のも
のに限られ、円柱状のものも成形できない。) Therefore, although the raw material is pressurized by centrifugal force, the raw material can only be molded into a cylindrical shape while adhering to the inner wall surface of the rotary cylinder, and even a cylindrical shape cannot be molded.
本発明は上記欠点の解決目的とし、具体的には、遠心力
のもとて炭素材料を加熱加圧成形するにも拘らず、角柱
状、または円柱状等の材料が直接に成形しかつ焼成でき
る製造装置を提案する。The purpose of the present invention is to solve the above-mentioned drawbacks, and specifically, although carbon materials are heated and pressed under centrifugal force, prismatic or cylindrical materials are directly molded and fired. We propose manufacturing equipment that can.
以下、図面によって本発明について詳しく説明する。Hereinafter, the present invention will be explained in detail with reference to the drawings.
まず、第２図ならびに第３図は本発明の一つの実施例に
係る炭素材料製造装置の回転胴部分の平面図と断面図で
あって、第１図に示す装置と同様に回転軸１１はその軸
線を中心として回転自在に構成される。First, FIGS. 2 and 3 are a plan view and a cross-sectional view of a rotating barrel portion of a carbon material manufacturing apparatus according to one embodiment of the present invention, in which the rotating shaft 11 is similar to the apparatus shown in FIG. It is configured to be rotatable around its axis.
この回転軸１１の周囲、つまりその半径方向に複数個の
原料投入容器１２を配置し、各原料投入容器１２には第
３図ならびに第４図に示す如く投入原料が角柱状、ブロ
ック状、レンガ状等や円柱状の焼成成型室を設ける。A plurality of raw material input containers 12 are arranged around this rotating shaft 11, that is, in its radial direction, and each raw material input container 12 contains raw materials in the shape of a prism, block, brick, etc. as shown in FIGS. 3 and 4. A cylindrical firing mold chamber is provided.
各投入容器１２と回転軸１１との間にはアーム１３を設
けて、これら投入容器１２は回転軸１１と一体化する。An arm 13 is provided between each input container 12 and the rotation shaft 11, and these input containers 12 are integrated with the rotation shaft 11.
このように構成し、各投入容器１２中に原料を入れて回
転させると、原料はその遠心力により加圧されて、各投
入容器１２において角状の材料が得られる。With this structure, when raw materials are put into each input container 12 and rotated, the raw materials are pressurized by the centrifugal force, and a square material is obtained in each input container 12.
また、原料を加熱するための加熱炉体１４は通常第３図
に示す如く、投入容器１２のところのみを包囲するよう
、加熱炉体１４を構成し、この加熱炉体１４の中心部に
は第３図に示す如く、上下に排気孔を形成する。Further, as shown in FIG. 3, the heating furnace body 14 for heating raw materials is usually constructed so as to surround only the input container 12, and the central part of the heating furnace body 14 is As shown in FIG. 3, exhaust holes are formed at the top and bottom.
このように加熱炉体を構成すると、各投入容器１２が回
転軸１１を中心として回転される間に、投入原料は遠心
力により遠心方向に加圧されつつ、焼成される。When the heating furnace body is configured in this way, while each charging container 12 is rotated about the rotating shaft 11, the charging raw material is fired while being pressurized in the centrifugal direction by centrifugal force.
しかし、焼成時に生成される気体は遠心力により投入原
料から分離され、加熱炉体１４の中心部に集まる。However, the gas generated during firing is separated from the input raw material by centrifugal force and collects in the center of the heating furnace body 14.
この点、中心部には排気孔が形成されているため、気体
は各排気孔から円滑に飛散し、所謂ガス抜けがきわめて
良好になって、緻密構造の炭素材料が成形と同時に焼成
できる。In this respect, since the exhaust holes are formed in the center, gas is smoothly dispersed from each exhaust hole, so-called gas release is extremely good, and a densely structured carbon material can be fired at the same time as being molded.
また、この加熱炉体１４は第１図に示すものと同様に通
常の低抗式電気加熱炉として構成しても、誘導加熱炉と
して構成することもできる。Further, the heating furnace body 14 can be configured as a normal low-drag electric heating furnace like the one shown in FIG. 1, or it can be configured as an induction heating furnace.
なお、回転軸１１の回転機構は第１図に示すものと同様
に構成すれば十分である。Note that it is sufficient if the rotation mechanism of the rotating shaft 11 is constructed in the same manner as shown in FIG.
例えば、各投入容器１２は通常耐熱鋼等から構成し、そ
の周囲の加熱炉体１４を抵抗式電気加熱炉として構成す
る場合は、第１図に示すものと同様に、内容器、外容器
、断熱材および電気ヒークから構成し、この電気ヒーク
で加熱できるよう構成する。For example, each input container 12 is usually made of heat-resistant steel or the like, and when the surrounding heating furnace body 14 is configured as a resistance electric heating furnace, the inner container, outer container, It consists of a heat insulating material and an electric heater, and is configured to be heated by the electric heater.
また、回転軸の後端はモークに連結し、モークによって
回転軸１１は回転させれば十分である。Further, it is sufficient to connect the rear end of the rotating shaft to a moke and to rotate the rotating shaft 11 by the moke.
また、上記のところではコークスとピッチの混合物から
炭素材料を製造する場合について説明したが、本発明装
置はこのような原料以外でも加熱時に流動化する粘結材
若しくは粘結材を含む原料であれば、いかなる原料も適
用できる。In addition, although the above explanation has been made regarding the production of carbon materials from a mixture of coke and pitch, the present invention apparatus can also be used to produce carbon materials from a mixture of coke and pitch. For example, any raw material can be applied.
したがって、例えば炭素繊維とピッチ若しくは樹脂、ピ
ツチ単味を原料として容易に所要の炭素材料が製造でき
、特に、炭素繊維とピッチから製造する場合は、焼成工
程中の剥離が全くないため、良質の炭素繊維一炭素複合
材が製造できる。Therefore, for example, the required carbon material can be easily manufactured using carbon fiber, pitch, resin, or pitch alone as raw materials. In particular, when manufacturing from carbon fiber and pitch, there is no peeling during the firing process, resulting in high quality carbon material. Carbon fiber-carbon composite materials can be produced.
なお、このように粘結材としてピッチを使用して炭素材
料を製造する場合に、市販のピッチは多量のガスが発生
するため、予めピッチを３００〜４５０℃で乾留してお
くのが好ましく、ピッチに代えて石炭も使用できるのは
勿論である。In addition, when producing a carbon material using pitch as a caking agent in this way, commercially available pitch generates a large amount of gas, so it is preferable to carbonize the pitch in advance at 300 to 450 ° C. Of course, coal can also be used instead of pitch.
