Abstract

PURPOSE:To provide the titled apparatus which enables the direct manufacture of a carbon material having a rectangular parallelepiped form, etc., by heating a raw material container attached to a rotary shaft through an arm and pressing the carbonaceous raw material containing a binder flowable under the heating condition by centrifugal force. CONSTITUTION:Plural rectangular parallelepiped containers 12 of a raw material made of a heat-resistant steel, etc. are fixed to a rotary shaft 11 through arms 13, and disposed to the radial directions. A raw material composed of an aggregate such as coke and a binder such as pitch, is charged in the container 12, and the container is rotated by a motor (not shown) through the rotary shaft 11 and heated with the furnace 14 to press the raw material by the centrifugal force. A rectangular parallelepiped carbon material having dense structure is formed in each container 12.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a carbon material manufacturing apparatus, and particularly to a carbon material manufacturing apparatus, in which a raw material containing a caking material, such as pitch, which becomes fluid when heated, is pressurized by centrifugal force under heating to form and then sinter. The present invention relates to a carbon material manufacturing device that simultaneously achieves this goal and can directly mold the carbon material into shapes such as squares and bricks.

Conventionally, most commonly, when producing all carbon materials, aggregates such as coke and caking materials such as pitch are used, and these materials are heated and kneaded at 140 to J50C, and then pressed, etc. Pressure molded, and the shape of the molded body was heated in a kiln for several days, 80 lbs. for a long period of 1 month.
0~] (Calculate and shape at a temperature of about 100C.)

However, when manufacturing in this way, the molding process and the firing process are carried out separately and independently, and the firing process lasts for a very long time, which poses problems in such a long-term phosphoric acid production process. In addition, during firing, some of the caking material becomes flakes and scatters, and the aggregate and caking particles are separated, and the scattered areas of caking material become pores. remains. Because of the defects caused by the scattering of the caking material during firing, the firing is carried out over a long period of time as described above, gradually increasing in temperature and causing the gas to slowly fly away. Even when fired in this way, a carbon material with a fairly dense structure could not be obtained.
It has the same air permeability of 8 degrees as normal artificial graphite. For this f'LK, Ryo P) is put into a rotating cylinder, heated from around this rotating cylinder, and heated while heating 7Jl.
A device that molds while being pressed by a force has also been proposed. However, materials with a dense structure can be manufactured using this packaging, but the material is limited to cylindrical shapes and cannot be manufactured into square, block, or brick shapes.

That is, FIG. 1 shows a rotary shell which is usually made of heat-resistant steel or the like, surrounded by a heating furnace body 2, so that the material inside the rotary shell 1 is sufficiently heated. The heating furnace body 2 normally has an inner container 2a1, an outer container 2b, a heat insulating material 2C, and a heater (not shown). The rotating body bottom plate is supported via the stopper 4 attached to the tip 33.n, Jf! D. The rear end of the rotating shaft 3 is rotated by the motor 5 through the six cooling oil seals 3b#-r.

(In addition, code 7 indicates the furnace lid, 8F:r raw material input pipe, 9 indicates the atmospheric gas inlet, and 1 (J indicates the waste waste pipe.))
Therefore, although the material is pressurized by centrifugal force, the material is only formed into a cylindrical shape while being layered on the inner wall surface of the rotary cylinder, and cannot be formed into a cylindrical shape.

The purpose of the present invention is to solve the above-mentioned drawbacks. Specifically, despite the fact that centrifugal force and T# composite material are heated and pressed,
We propose a manufacturing device that can overlaply mold materials such as squares, blocks, and bricks.

9F, the present invention will be explained in detail with reference to the drawings.

1. If Fig. 2 is the same, Fig. 3 is a plan view and a cross-sectional view of a rotary barrel portion of a carbon material manufacturing apparatus according to an embodiment of the present invention. IW] Rotation axis 1] Keso axis #? The rotation angle M-vcm is set as the center ≧j. A plurality of 12 raw material input containers are arranged around this rotating shaft 1 in the radial direction thereof, and each input container 2 and the rotating shaft 11
An arm 13 is provided between the two and a charging container 12.
is integrated with the rotating shaft 1]. With this structure, when the bookkeeping container 1 is placed in each input container 12 and awn is rotated, the raw material is pressurized by the centrifugal force, and a square material is obtained in each input container 12. Ru.

The heating furnace body 140 for heating is usually constructed so as to completely surround only the charging container 12, as shown in FIG. It can be constructed either as a normal resistance type electric heating furnace or as a rust induction heating furnace.

In addition, it is sufficient that the rotational axis is similar to that shown in FIG.

9Ile, when each input container 12 is made of a heat-resistant material, etc., and the surrounding heating furnace body 14 is configured as a resistance electric heating furnace, an inner container, similar to that shown in FIG. It consists of an outer container, a heat insulating material, and an electric heater, and is configured so that it can be heated by this electric heater. In addition, it is sufficient to connect the rear part of the rotary shaft to a motor, and to rotate the rotary shaft IHff by the motor.

1fc, Ttff Above, we have described the case of producing a carbonaceous material from a mixture of coke and pitch, but the apparatus of the present invention a also contains a caking agent or a caking agent that is activated by Kfl when heated. Any raw material can be used for Tort.

Therefore, the required carbon material can be easily produced as a single bonding material such as carbon fiber, pip, resin, or pitch, and in particular, when it is produced from carbon fiber and pitch, there is no peeling during the firing process. Therefore, high quality carbon fiber-carbon composite materials can be manufactured.

In addition, when producing a carbon material using Pitchke as a caking agent in this way, since commercially available pitch generates a large amount of gas, it is preferable to carbonize it in advance at Pitchke 300-450C. Of course, coal can also be used instead.
