BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a melt outlet structure of a melting furnace for heating and melting industrial waste such as asbestos.

[0002]

2. Description of the Related Art Industrial waste, such as asbestos from building waste, is harmful if it is directly disposed of in landfills. Therefore, glass fragments are added to heat and melt, and this molten metal is dropped into cooling water. It is then solidified into glass.

By the way, in a conventional melting furnace for melting such industrial waste, as shown in FIG.
A V-shaped discharge groove 52 for discharging the molten metal was formed in the side wall portion 51a on one end side of the furnace body 51.

[0004]

However, according to the above-mentioned conventional structure, the level of the molten metal in the furnace main body 51 is always in the state of being almost coincident with the bottom of the discharge groove 52.
On the inner wall surface of No. 1, erosion a occurred along the molten metal surface, and there was a problem that the service life of the furnace body was short.

Therefore, an object of the present invention is to provide a molten metal outlet structure of a melting furnace for industrial waste which can solve the above problems.

[0006]

In order to solve the above problems, the first means of the present invention is to discharge another molten metal below a discharge groove for discharging the molten metal formed in the side wall of the furnace body. It is a molten metal outlet structure of an industrial waste melting furnace in which a through hole is formed and a removable plug is attached to the through hole.

The second means of the present invention is that the lower end surface is in the first discharge groove for discharging molten metal, which is formed in the side wall portion of the furnace body and has a predetermined bottom surface shape. 1 It is shaped to match the bottom surface of the discharge groove and is
It is a molten metal outlet structure of an industrial waste melting furnace in which a weir body in which a second discharge groove having the same shape as the discharge groove is formed is detachably mounted.

[0008]

In each of the above constructions, first, the molten metal in the furnace body is discharged from the discharge groove formed in the furnace body or the second discharge groove formed in the upper surface of the weir body.

Then, as time goes by, when the periphery of the inner wall surface of the furnace body is eroded along the molten metal surface,
The plug is removed to discharge the molten metal from the through hole, or the weir is removed to discharge the molten metal from the first discharge groove formed in the side wall of the furnace body.

Therefore, the service life of the furnace body can be doubled.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIGS. In FIG. 1, reference numeral 1 denotes a furnace body of a melting furnace for melting industrial waste such as asbestos, and a V-shaped discharge groove 2 for discharging molten metal is formed on a side wall portion 1a on one end side thereof. A through hole 3 for discharging the molten metal is formed at a position below the discharge groove 2 of the side wall portion 1a by a predetermined distance, and a removable plug (not shown) is attached to the through hole 3.

In the above structure, first, the through hole 3 is formed.
With the stopper attached inside, the molten metal in the furnace body 1 is discharged by V
It is carried out from the character-shaped discharge groove 2. When this discharge groove 2 is used, as shown in FIG. 2, erosion a occurs around the inner wall surface of the furnace body 1 along the molten metal surface.

When this erosion progresses to some extent, the plug attached to the through hole 3 may be removed and the molten metal may be discharged from the through hole 3. Therefore, erosion is newly generated on the inner wall surface of the furnace body 1 at the position of the through hole 3, so that the furnace body 1
The service life of can be further extended. That is, the service life of the furnace body is doubled as compared with the conventional configuration.

Next, a second embodiment of the present invention will be described with reference to FIG. In the first embodiment described above, the through holes for discharging the molten metal are provided below the discharge groove, but in the second embodiment, the discharge grooves are provided at the upper and lower portions.

That is, the side wall portion 1a on one end side of the furnace body 1
The inside of the first discharge groove 11 for discharging the molten metal, which has a predetermined discharge part shape, that is, a V-shaped bottom surface.
The lower end surface has a shape matching the bottom surface of the first discharge groove 11, and the upper end surface has the same V as the bottom surface of the first discharge groove 11.
V-shaped weir body 1 having a V-shaped second discharge groove 12
3 is detachably attached from above.

In this construction, first, the melting furnace is used with the V-shaped dam body 13 mounted in the first discharge groove 11. That is, the molten metal in the furnace body is discharged to the outside from the V-shaped second discharge groove 12 formed on the upper surface of the weir body 13.

Also in this case, when the inner wall surface of the furnace main body is eroded, the weir body 1 inserted in the first discharge groove 11 is formed.
When 3 is pulled upward, the molten metal is discharged from the first discharge groove 11 this time.

In this case as well, the service life of the furnace body is 2
It can be doubled. Next, a third embodiment of the present invention will be described with reference to FIG. In the second embodiment described above, the V-shaped weir body is mounted in the first discharge groove, but this third
In the embodiment, as shown in FIG. 4, the rectangular first discharge groove 2 for discharging the molten metal formed in the side wall portion 1a of the furnace body.
A weir body 2 having a rectangular shape in a front view and a trapezoidal shape in a plan view in 1
2 is detachably attached. In addition, weir body 2
The height of 2 is, for example, about half of the depth of the first discharge groove 21, and the second discharge groove 23 is formed above the weir body 22 at the time of mounting. That is, two rectangular discharge grooves 21 and 23 are provided on the upper and lower sides, and the same effect as each of the above-described embodiments is obtained.

[0019]

As described above, according to the configuration of the present invention, two discharge portions, such as a discharge groove for discharging molten metal and a through hole, are provided on the side wall of the furnace body. The service life of the main body can be doubled.
