ものである。(Prior art) Among the above-mentioned high-temperature, high-pressure reaction treatment techniques, the most well-known method for carrying out a reaction while maintaining a liquid phase is the autoclave method, in which the material to be treated is placed in a reaction vessel with a closed lid. There are various types such as stationary type, stirring type, and rotating type.Here, an example of the stirring type is shown in Figures 5 and 6. , and its outline will be explained. The one shown in FIG. 5 is a vertical stirring type autoclave 102 which is held in an electric heating furnace 101 and can be heated. 105, a thermometer insertion port 106, a stirring shaft 107, etc. are arranged,
The flowable slurry-like material to be treated, which is made by suspending liquid or solid particles in a liquid medium, stored in the autoclave 102 is subjected to a high-temperature, high-pressure reaction treatment by supplying high-pressure gas and heating the material. At this time, a stirring shaft 107 is used to uniformly mix the contents.The one shown in FIG. 6 is a horizontal stirring type, and the same reference numerals indicate the same members. With this type, gas can be constantly circulated during the gas-liquid reaction, and the horizontal type has an excellent stirring effect.

知のように熱間静水圧（等方圧）成形装置が存在する。However, this autoclave type is a batch type and uses an externally heated pressure vessel to perform high temperature and high pressure treatment, so there is a problem with the high temperature strength of the pressure vessel, and it is difficult to achieve this from the standpoint of safety and pressure resistance. There are limits to the possible temperature and pressure conditions, and as an alternative,
A continuous autoclave method using a pipeline system has also been developed for industrial mass production and mass processing.
This is considered to be effective when a hydrothermal reaction utilizing the vicinity of the critical point of water is carried out industrially, and its outline will be explained with reference to FIG. The figure is a principle system diagram of a pipeline-type continuous hydrothermal reaction system.The flow of the sample from the raw material tank is explained according to the diagram.The raw material pushed out from the raw material tank by the compressor passes through continuous pipe A, and passes through the check ball. The paste is sent from valve B to paste pump C, where it is pressurized with air at several hundred atmospheres. The sample sent out from paste pump C passes through a check ball valve, is preheated in heat exchanger 0, and is given a predetermined temperature in reaction column F. The passage time in the reaction tower is determined by the length of the reaction tube in the reaction tower and the flow rate, so in order to increase the throughput, the reaction tube must be made longer to increase the flow rate, the reaction temperature must be increased, or The catalyst is used to shorten the reaction time. Thus reaction tower F
The sample sent from the pump is cooled and heated at the same time through the heat exchanger 0, and then enters the discharge pump I through the ball valve H, where the discharge pressure is used as the pressure during injection. The product delivered from the discharge pump I is transferred to the ball valve J
It passes through the pressure-controlled pulp K and is taken out.
The flow rate and flow rate are controlled by the rotational speed of the injection pump and the piston stroke length of the plunger pump, but are also related to the internal pressure, which can be adjusted via the pressure regulating pulp. In addition, there is a well-known hot isostatic pressure (isostatic pressure) forming apparatus that performs high-temperature, high-pressure treatment on a material to be treated in a high-pressure container.

装置としてよく知られている。As will be described later in detail in the present invention, the device is a cylindrical container that is open at both ends in the axial direction, and a means for supplying pressurized gas into the interior of a high-pressure container constructed by compressively closing an upper lid and a lower lid to the openings of the cylindrical container. A furnace chamber equipped with heating means such as an energized heater is provided, powder materials such as metals and ceramics are charged and set in the furnace chamber, and sintered products are formed under ultra-high pressure and high temperature.

。That is, in the autoclave system using a single reaction vessel, there are disadvantages due to the number of batches, and furthermore, there are limits to the temperature and pressure conditions that can be achieved, and these limits are forced to be within a considerably low range. In addition, the continuous autoclave method using a pipeline system is superior in that high temperature and high pressure processing can be performed continuously, but the basic configuration of temperature and pressure is the same as that of a conventional single autoclave, so the temperature that can be achieved is , pressure conditions have similar limitations.

るものである。(Function) According to the above-described technical means of the present invention, as shown in FIG. 1, both ends in the axial direction are opened, and both the upper M2 and lower M3 can be opened and closed in a pressure-sealed state in both openings. In a high-pressure vessel 1 that is closed, a heating device 4 such as an energized heater is built into the vessel 1 via a heat insulating layer 5, and a pressure medium passage 25 communicating with the inside of the high-pressure vessel 1 is provided in the upper M2.
By providing the above, a known hot isostatic pressing apparatus is constructed. Although not shown in the figure, as is known, in this type of hot isostatic pressing apparatus, the axial force applied to the upper and lower lids during pressure molding is absorbed by the press frame that holds the upper and lower lids. In the present invention, a high-temperature and high-pressure processing inner cylinder 6 is installed concentrically inside the heating device 4 of the high-pressure vessel 1, and both axial ends of this high-temperature and high-pressure processing inner cylinder 6 are connected to the It is connected to the upper lid 2 and the lower lid 3 under a pressure-sealed state by the seals 7 and 8, and both ends of the inner cylinder 6 are communicated with the inlet/outlet 9.lO for the material to be processed provided in the upper lid M2 and the lower lid 3. Therefore, there is a supply pipe 1 for the material to be treated at the entrance/exit 10 of the lower cover 3.
9 is connected, and the supply tank 17 for the material to be treated is connected to the same pipe 19.
A pressure medium pump 18 for pressure feeding made of the same material is provided together with a blocking valve 22 and a pressure gauge 24 for pressure detection, and a discharge pipe 21 for the material to be treated is connected to the inlet/outlet 9 of the upper lid 2.
9 is provided with flow path resistance members such as a blocking valve 23 and a throttle valve 20, and a recovery tank 41. First, pressure medium is supplied from the gas collecting device 26 to the compressor 27 through the pressure medium passage 25 inside the high-pressure vessel l. (gas) is supplied under pressure through the supply pipe 28, and the flowable material to be processed, such as a slurry-like material in which gas, liquid, or solid particles are suspended in a liquid medium, is transferred to the high-temperature and high-pressure processing inner cylinder 6 under pressure resistance. While maintaining the differential pressure between the inside and outside of the inner cylinder within the allowable range (it is preferable that the pressure medium on the hot isostatic pressing device side is always higher than the pressure inside the high temperature and high pressure processing inner cylinder 6), the pressure inside the tank 17 is maintained. The material to be treated is transferred to the pressure medium pump 18.
The blocking valve 22 is opened to supply the engineering university, and at this time, the blocking valve 23 and throttle valve 2 in the pipe 21 on the upper cover 2 side are opened.
0 is in the closed state, the material to be processed is held in the high temperature and high pressure processing inner cylinder 6, the heating device 4 is started to heat the pressure medium to raise the temperature, and after reaching a predetermined temperature, the pressure medium pump is turned off for one day. is continuously driven, and the blocking valve 23 and throttle valve 2 on the discharge piping 21 side are operated continuously.
This makes it possible to carry out high-temperature, high-pressure reaction treatment under predetermined temperature and pressure conditions while continuously discharging materials under heating and temperature rise from zero. At this time, connect the lower end of the insulation layer 5 to the lower lid 3.
On the other hand, by keeping it airtight through the seal 12, the flow of the pressure medium gas circulating inside and outside the heat insulating layer 5 is suppressed,
It is possible to exhibit good heat insulation function, and at the same time, it is possible to increase the heating effect. This improves the point that conventional hot isostatic forming equipment is only used for block-shaped solid phase materials, such as removing defects in powder molded products, sintered crystals, and cast products. Continuous high-temperature, high-pressure reaction treatment of flowable materials such as ceramic bodies can be carried out under significantly higher temperature and pressure conditions than those of conventional autoclave technology. At the same time, it eliminates the inefficiency of batch-type isostatic pressure forming equipment in which the container lid is opened every time a cycle is completed to carry in and take out the material, and it is possible to This makes it possible to realize mass processing and mass production plans without asking any questions.

されることになる。(Embodiments) Contents of appropriate embodiments of the processing apparatus according to the present invention will be sequentially explained with reference to FIGS. 1 to 4. The example shown in Fig. 1 is the basic type of the apparatus of the present invention, and in the figure, the high-pressure vessel 1 is cylindrical with both ends opened in the axial direction, and forms the main body of the hot isostatic pressing apparatus. It is something. An upper M2 and a lower M3 are each fitted into the opening so as to be closable under a pressure-sealed condition. As is known, a heating device 4 such as an energized heater is provided inside the high-pressure container 1 via a heat insulating layer 5, and both 4 and 5 constitute heating and temperature raising means. Reference numeral 11 denotes a furnace chamber surrounded by heating and temperature increasing means, and this furnace chamber functions as the high temperature and high pressure reaction treatment chamber 11 in the present invention. These have a known structure as a conventional hot isostatic pressing device (the press frame for supporting the axial force is not shown), but in the present invention, they are located inside the heating bag M4 and are placed up and down in the axial direction. A cylindrical high-temperature, high-pressure processing inner cylinder 6 with both ends open is concentrically installed inside the cylinder, and in this embodiment, the inner cylinder 6 corresponds to the inner cylinder, and the upper and lower ends of the inner cylinder 6 in the axial direction are both sealed through seals 7 and 8. Upper II2 and lower lid 3
It is connected under pressure seal condition. At this time, considering the elongation of the inner cylinder 6 due to the temperature rise during heating, the inner cylinder 6
It is preferable that one end is movably connected in the axial direction so that even if the upper end in the axial direction is fixed to the upper lid 2 side, the lower end in the axial direction is tightly fitted to the lower M3 so as to be slidable in the axial direction. In addition, this high-temperature, high-pressure processing inner cylinder 6 is connected to the upper and lower M2 and 3, thereby communicating with the inlet/outlet 9 for the material to be processed opened on the upper M2 side and the same inlet/outlet 10 opened on the lower lid 3 side. As a result, a high-temperature, high-pressure treatment chamber for the material to be treated having entrances and exits 9 and 10 on the upper and lower sides is formed, sharing the forming furnace chamber 11 of the high-pressure vessel l.

This is effective in keeping one end of the heat insulating layer 5 airtight in the axial direction, thereby suppressing the flow of the pressurized gas circulating inside and outside the heat insulating layer, and achieving a good heat insulating function. As this means for suppressing the flow of pressurized gas, the axially upper end of the heat insulating layer 5 may be held airtightly on the upper lid 2 side via a seal, or it may be held against the inner wall surface of the upper end or the inner wall surface of the lower end of the pressure vessel I. It may be held airtight in the same way, or furthermore, it may be held airtight at the upper or lower end of the outer peripheral surface of the high-temperature, high-pressure processing inner cylinder 6.

While holding the material to be press-fitted in the inner cylinder 6, heating is performed by the heating device 4, and when the predetermined temperature is reached, the pressure medium pump 18 is continuously driven, and the throttle valve is opened. 20, while continuously discharging under pressure, a high temperature and high pressure reaction treatment is carried out under the desired temperature and pressure conditions. At this time, the pressure of the pressure medium on the high pressure vessel l side is within a predetermined differential pressure range with respect to the processing pressure of the material to be processed, that is, the inner cylinder pressure, and the pressure on the high pressure vessel l side is slightly higher.
This is preferable from the viewpoint of preventing damage troubles such as breakdown of electrical insulation in the components of the hot isostatic pressing apparatus, especially the heating device 4, due to damage to the seal of the inner cylinder.
