BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a flange used for a container or the like and a fuel cell equipped with the flange.

In general, it is an important factor to maintain the temperature of the reaction part and to minimize the heat loss to the outside in a process requiring high temperature operating conditions. Typical high-temperature processes include processes using high temperature molten salt such as metal oxide electrolytic reduction process, electrolytic smelting process, and electrolytic refining process. Conventionally, in order to maintain the temperature of the reaction part, as shown in FIG. 1, a metal plate or a heat insulating material is used for the flange, and the heat sink 116 is fixed.

Referring to FIG. 1, an operation device 100 having a closed-type flange includes an outer reactor 122 positioned at a contact portion with the heating furnace 130 and an inner reactor 124 reacting with the outer reactor 122, As shown in FIG. The inner reactor 124 may be made of ceramics when a reactant having high reactivity with various metals such as stainless steel, inconel, tantalum, and the like is handled. In the case of the above-mentioned reduction, refining, and smelting processes, since the electrochemical reaction is used, the flange may be provided with a heat sink 116 as well as an entrance of an anterior theater.

In the above-described operating apparatus 100, a gap may be formed between the width of the heat radiating plate 116 and the width of the external reactor 122 to generate heat loss. In the case of the flange 110, The width of the heat sink 110 is formed to be smaller than the width of the external reactor 122, since disassembly must be possible at the same time. Further, in the process using molten salt, when the volatile salt is fixed to the gap between the heat sink 116 and the external reactor 122, the disassembly of the flange 110 becomes impossible. Thus, a method of reducing the heat loss from the reactor 120 and facilitating the fastening and dismounting of the flange 110 can be considered.

It is an important requirement that the high temperature reactant contained in the vessel is minimized in heat loss to the outside, and the vessel may contain a reactant requiring a low temperature state. The body 210 may be formed to cover the upper part of the container which is opened at one side by a load, or may be combined with the container by using a separate fastening element.

The rod 220 may extend from one side of the body 210 in the direction of the container. The end surface of the rod 220 may be formed in a circular shape to facilitate the movement of the first plate 240, but may be formed in a shape other than circular. 2A and 2B, the plurality of rods 220 may be formed to stably include the first plate 240 on the rod 220. In addition,

The first plate 240 is formed to be reciprocable along the rod 220, and may be formed to be closed by lowering by a load. More specifically, the first plate 240 and the rod 220 are formed with a tolerance such that sliding occurs on the surfaces contacting with each other. Accordingly, as shown in FIG. 2A, the first plate 240 is lowered in the container direction by a load in a state where the flange 200 is disassembled from the container.

On the other hand, when the flange 200 is coupled to the container, as shown in FIG. 3A, the lower surface of the first plate 240 is brought into contact with the corresponding inner surface of the container. Accordingly, the first plate 240, which is lowered in the container direction due to the load, moves relative to the rod 220 and is lifted to seal the container.

The first plate 240 may be coupled to the rod 220, Referring to FIG. 2A, the first plate 240 is lowered by a load when the flange 200 is disassembled from the container. At this time, the lower surface of the first plate 240 is caught by the separation preventing portion formed to protrude from the rod 220. Accordingly, the movement of the first plate 240 is limited, and the deviation from the rod 220 can be prevented.

The reactor 320 may further include an external reactor 322 disposed in contact with the heating furnace 330 and an internal reactor 324 disposed inside the external reactor 332.

The reactor 320 may include a locking portion 327 protruding inward. 3A and 3B, a part of the external reactor 322 is formed to be stepped. However, the latching part may be formed in other forms such as concave and convex so as to correspond to the lower surface of the first plate 313. In addition, the first plate 313 may be formed so that the lower portion of the first plate 313 is stepped so that the first plate 313 can be engaged with the engaging portion 327.

3B, when the flange 310 is engaged with the reactor 320, the stepped portion formed on the first plate 313 is caught by the engaging portion, so that the first plate 313 is fixed to the rod 320, It is possible to increase the pressure in the reactor 320 and to close the reactor 320.

The second plate 315 may be formed to cover the inner reactor 324. The second plate 315 may further include a release preventing portion below the rod 312 to which the first plate 313 is coupled. . Thus, as shown in FIG. 3A, when the flange 310 is disassembled from the reactor 320, it is possible to further reduce heat loss from the reactor 320 while preventing dislodgment of the first plate 313 have.

Further, a third plate 317 may be further provided on the first plate 313. The third plate 317 is formed so that the movement of the third plate 317 is fixed by the rod 312. The third plate 317 may be formed to be close to the inner surface of the outer reactor 322 to facilitate the fastening and disassembly of the flange 310 from the reactor 320.

In addition, the third plate 317 may be formed as a plurality of spaced apart from each other so as to reduce heat loss from the reactor 320 by forming a plurality of air layers having low thermal conductivity.

In addition, the first to third plates 313, 315, and 317 may further include a thermal conductor having a thermal conductivity of less than a certain level to reduce heat transfer from the reactor 320. At this time, the heat conductor may be included inside or outside the first to third plates 313, 315, and 317.

According to the present invention described above, since the clearance to the reactor 320 is removed by the first plate 313 formed in close contact with the reactor 320, the heat loss from the reactor 320 can be reduced.

In addition, the reactor 320 may contain volatile reactants, such that the clearance between the reactor 320 and the first plate 313 is eliminated, thereby preventing loss of reactants through the clearance, The difficulty of fastening and disassembling the flange 310 due to the fixing phenomenon of the reactant that may be generated can be solved.

It should be understood, however, that the scope of the present invention is not limited to the embodiments described above, but may be modified and changed without departing from the spirit and scope of the present invention as defined by the appended claims. It is obvious that the invention belongs to the scope of the present invention.
