DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a burner device for an anvil which is used by being attached to a furnace for firing an anvil tile.

[0002]

2. Description of the Related Art In a fired sintering furnace, it is necessary to immediately close the burner opening in a high temperature state immediately after the completion of sintering by a burner and to fill the furnace with a smoking agent to perform smoldering. For this purpose, various burner devices have been proposed. For example, in Japanese Utility Model Publication No. 52-47152 and Japanese Utility Model Publication No. 52-50430, a cylinder with a handle is screwed into the tip of the burner, and after the burner is stopped, a shielding plate is provided between the burner and the furnace wall. There is shown a burner device for an anvil that can be inserted and then advance the cylinder to press the shielding plate. However, since a large number of burners are provided around the furnace, it takes a considerable amount of time to rotate the cylinder and press the shielding plate for each burner, and during this time troubles such as intrusion of outside air occur. Occurred.

Further, as disclosed in Japanese Utility Model Publication No. 58-55314, there has been proposed a burner apparatus for an anvil in which a shield plate is pressed against a furnace wall by the force of a spring to seal a burner port. This device can seal the burner opening relatively quickly, but if the spring deteriorates due to heat, the sealing of the burner opening will be incomplete, and the spring force will be directly pressed by the burner opening. However, there is a danger that the burner port will be degraded because of the burner opening.

[0004]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems and can quickly and reliably seal the burner port after the burner is stopped, thereby providing a large number of burners. The invention has been completed in order to provide a burner device for an anodized roof that can minimize troubles such as intrusion of outside air even in an oven fired kiln.

[0005]

SUMMARY OF THE INVENTION The object of the present invention is to provide a frame plate provided on a furnace wall outside a burner opening, in which a slide plate which can be brought into contact with and separated from the frame plate is attached, and a burner body is attached to an outer surface of the slide plate. And a shielding plate inserted between the slide plate and the frame plate when the slide plate separates, and a toggle clamp that can press the slide plate toward the frame plate by operating the handle is attached to both sides of the frame plate It can be solved by a burning burner device characterized in that:

[0006]

According to the present invention, the burner device of the present invention operates the handle after stopping the burner to release the pressing of the frame plate by the toggle clamp, and separates the slide plate from the frame plate. In this state, the shield plate is inserted between the slide plate and the frame plate, and the handle is again operated to press the slide plate toward the frame plate by the toggle clamp. As a result, the shielding plate comes into close contact with the frame plate by the strong clamping force of the toggle clamp, and the burner opening can be quickly and reliably closed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in more detail with reference to the illustrated embodiments. In FIG. 1, reference numeral 1 denotes a furnace wall of an anvil tile firing furnace, 2 denotes a burner port formed in the furnace wall 1, and 3 denotes a frame plate provided on the furnace wall 1 outside the burner port 2. As shown in FIGS. 2 and 3, a pair of guide rods 4 are protruded near the left and right ends on the outside of the frame plate 3. A slide plate 5 is provided which can be moved toward and away from the frame plate 3.

At the center of the outer surface of the slide plate 5, a burner main body 6 is fixed. The burner main body 6 is provided at a position aligned with the above-described burner port 2 and blows a frame into the furnace through the furnace wall 1 to fire the tile in the furnace.

On both sides of the frame plate 3, there are attached toggle clamps 7 capable of pressing the slide plate 5 toward the frame plate 3 by operating a handle. The toggle clamp 7 has an arm 9 that can swing around the upper first pin 8 and a short link 11 that can swing about the lower second pin 10.
The upper end is pivotally connected to the arm 9 by the pin 12, and the lower portion is slightly fixed to the upper end of the short link 11 by the pin 13.
And a lock lever 16 pivotally connected to the handle lever 14 by a pin 15 on the handle lever 14.

The toggle clamp 7 has a lock lever 16
In the direction approaching the lower end of the handle lever 14,
When the position of the pin 13 is moved to the furnace wall 1 side with respect to the straight line connecting the pin 12 and the second pin 10, the arm 9 can swing about the first pin 8. Is a mechanism in which the arm 9 is locked when it is also outside. In addition, this mechanism is a booster mechanism and can perform strong clamping. The slide plate 5 can be pressed toward the frame plate 3 by a clamp bolt 17 attached to the upper portion of the arm 9 so as to be adjustable in length.

As shown in FIG. 4, between the frame plate 3 and the slide plate 5, there is provided a shielding plate 18 which can be inserted between the slide plate 5 and the slide plate 5 when the slide plate 5 is separated from the frame plate 3.
The shielding plate 18 is a plate for shielding the burner port 2 to prevent the entrance of outside air, and is moved to an upper portion of the frame plate 3 during burning of the burner.

The burner device for an smolder of the present invention having the above-described structure is constructed by first bringing the slide plate 5 into close contact with the frame plate 3 as shown in FIGS.
Is fired while facing the burner port 2, and immediately after the firing, the toggle clamp 7 is operated to release the pressing of the slide plate 5, and the slide plate 5 is separated from the frame plate 3. Then, the shielding plate 18 is dropped into the gap from above, and the toggle clamp 7 is operated again to operate the slide plate 5.
With a strong force. As a result, the burner port 2 is reliably sealed by the shielding plate 18, and the ingress of outside air is prevented. Thereafter, a smoking agent is injected as in the prior art, and smoldering is performed.

[0013]

According to the present invention, as described above, the slide plate 5 can be pressed or released by operating the toggle clamp 7, and compared to the conventional screw type, it can be operated in a short time with one touch. In addition to the above-mentioned operation, unlike the conventional spring type, there is no fear of deterioration of the pressing force due to heat. Therefore, according to the present invention, it is possible to quickly seal the burner port even in a refractory tile firing furnace having a large number of burners.
