[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of an under top burner furnace used for firing various ceramic products.

[0002]

2. Description of the Related Art An under-top burner furnace in which burners are alternately arranged on the upper and lower sides of a furnace wall can achieve a uniform furnace temperature by a swirling flow formed in the furnace. It is used for firing various ceramic products. However, the conventional undertop burner furnaces are all topping furnaces having exhaust holes formed in the ceiling, and have a structure in which high-temperature exhaust gas is blown out from the furnace body ceiling. For this reason, the ceiling of the building needs to be at least 2 m higher than the upper surface of the furnace body, so that a high building is required and this space is wasted.

[0003]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems, and can be installed in a building with a low ceiling, and can exhibit the same performance as the conventional one. It was completed to provide a burner furnace.

[0004]

In order to solve the above-mentioned problems , the under-top burner furnace according to the present invention has burners arranged at the upper and lower portions of a furnace wall , and a combustion gas is provided in the furnace.
Whirl flow is generated to fire the material to be fired,
A plate-like column supporting the fired material is placed on the floor of the furnace body by the swirling flow.
Under-top burner furnaces
The space partitioned by the plate-shaped support,
Circulates through the space where the combustion gas of the burner blows and the furnace.
With exhaust holes on the floor to exhaust combustion gases
It is characterized in that the spaces are alternately arranged .

[0005]

The under-top burner furnace of the present invention forms a swirling flow in the furnace by combustion gas blown into the furnace from burners arranged alternately at the upper and lower parts of the furnace wall,
Uniform firing of the object to be fired is the same as in a conventional furnace of this type. However, in the present invention , the injected combustion gas
Since the subbing furnace forming an exhaust hole in the floor of partitioned furnace body plate struts from the high temperature exhaust gas is blown retardant
Low interference with combustion gas
In addition, the gas is sucked from the exhaust hole at the lower part of the furnace body and guided to the flue, so that the high-temperature exhaust gas does not blow out from the ceiling of the furnace body as in the related art. For this reason, the ceiling of the building can be lowered, and the same sintering performance as before can be exhibited.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the illustrated embodiments. 1 and 2, reference numeral 1 denotes a furnace body, 2 denotes a door thereof, and 3 denotes a bogie to be charged into the furnace with the door 2 opened.
Is the wheel and 5 is the rail. Burners 6 are arranged at alternate positions on the upper and lower portions of the furnace wall on both sides of the furnace body 1 so that swirling flows in opposite directions are formed at respective cross-sectional positions in the furnace. The + mark indicates that the burner 6 is provided on the opposite furnace wall (not shown).

[0007] In the embodiment, and an internal exhaust passage 7 of the carriage 3 is formed, the lower end surface of the exhaust passage 7 of the furnace body 1 when setting the carriage 3 in the furnace as shown in FIG. 1, 2 At the same time as the flue 8 formed. In addition, a number of plate-like columns 9 are erected on the upper surface of the cart 3,
The object 10 to be fired is placed on the upper surface of these columns 9, and the burners 6 , 6 at the lower part of the furnace wall are placed in the space formed by these plate-shaped columns 9 , 9 .
It is located toward . The lower burners 6 , 6 are located in the space between the columns 9, 9.
The above-described exhaust passage 7
An exhaust hole 11 communicating with the lower end is formed to constitute a lowering furnace.

In the under-top burner furnace of the embodiment configured as described above, a bogie 3 on which an object to be fired 10 is mounted is charged into the furnace as shown in the figure, and an exhaust passage 7 formed in the bogie 3 is provided.
Is fired by a burner 6 by bringing the end face of the burner 6 into close contact with a flue 8 formed at the lower part of the furnace body 1, and the combustion blown into the furnace from the burners 6 arranged alternately at the upper and lower parts of the furnace wall. A swirling flow is formed in the furnace by the gas, and the object to be fired 10 is uniformly fired. At this time, the lower burner 6 is a plate-like support 9 for supporting the object 10 to be fired,
Located in the space between the 9, so that the blown into the furnace along the direction of the swirling flow of combustion gases from the lower surface of the baked product 10. The exhaust gas in the furnace is sucked into the exhaust passage 7 from the exhaust holes 11 formed in the lower burners 6 , 6 in the space between the columns 9, 9 as shown by arrows in FIG. The gas is exhausted to the outside through the flue 8 of the furnace body 1. This
The flow of combustion gas and the flow of exhaust gas
Are separated by plate-like columns, so they interfere with each other
Less is.

[0009]

As described above, the under-top burner furnace of the present invention forms a strong swirling flow in the furnace in the same manner as a conventional furnace of this type, thereby uniformly firing the object to be fired. be able to. In addition, since the exhaust gas in the furnace is drawn out from the lower part of the furnace body, the lowering furnace is used, so that the high-temperature exhaust gas does not blow out from the ceiling of the furnace body as in the related art, and can be installed in a building with a low ceiling. For this reason, there is also an advantage that a wasteful space above the furnace body, which was conventionally required, can be eliminated. By forming the exhaust hole between struts burner of the lower portion is not provided in a further, blown
Since there is little mutual interference between the combustion gas and exhaust gas
A combination of an under-top burner furnace and an underdrawing furnace, which has not been known, can be realized without difficulty. Therefore, the present invention has an extremely large practical value as an under-top burner furnace which solves the conventional problems.
