Description

Double structure kiln}

The present invention relates to a dual structure kiln, and more particularly, to a double structure kiln used for gratings and chaebols for pottery.

Generally, a kiln is a device used for performing a heat treatment process such as firing and melting, and is mainly used for manufacturing ceramics.

For example, a common kiln used in the manufacture of ceramics is repeatedly carried out in a firing chamber in the form of griddles and chaebols. A conventional method of manufacturing a ceramic article will be described. First, a ceramic article dried through a molding operation is carried into the firing chamber. Then, the inside of the firing chamber is heated by a heat source at a temperature suitable for the pre-baking, about 800 to 850 ° C, and the pre-firing of the ceramic article is performed. After that, the ceramics which have been completed are transferred to the outside of the firing chamber, and the glaze is applied to the firing chamber again. Thereafter, the inside of the firing chamber is reheated at a temperature suitable for the chaebol, about 1200 ~ 1350 ℃, and the chaebol is roasted on the ceramics.

As described above, in the conventional method for manufacturing ceramics, a single firing chamber is used to apply glaze to ceramics, followed by grinding and grinding. At this time, it takes about 5 hours to heat the firing chamber to an appropriate temperature for the ungulk, and it takes about 6 to 7 hours for the firing chamber to be heated to the proper temperature for the chrysol. Also, in order to perform the ungulking of other ceramics after the completion of the chaebol, the internal temperature of the firing chamber should be cooled to 150 ° C in order to prevent breakage of the ceramics due to the rapid temperature change. At this time, it takes at least one day to cool down the firing chamber.

That is, in the conventional kiln made up of one firing chamber, time is consumed more than necessary such as the time consumed in the ungulk, the time consumed in the roasting of the chrysanthemum, the time required for cooling the firing chamber, and the time spent in reheating the firing chamber, There is a problem that the productivity is lowered. In addition, in the conventional method of manufacturing ceramics, there is a problem that production cost is increased due to excessive consumption of fuel and environmental pollution occurs due to increase of carbon dioxide emission.

The object of the present invention is to provide a dual structure kiln which provides a plurality of firing spaces in the firing process for ceramics.

The dual structure kiln according to the present invention includes a first firing portion provided with a heat from a firebox, a second firing portion disposed apart from the first firing portion, and a second firing portion between the first firing portion and the second firing portion, And a connection part for connecting the first and second fired parts to the first fired part and the second fired part, the first fired part being connected to the firing chamber and the connection part being communicated at one side, And a second firing unit disposed between the second firing unit and the first firing unit to generate heat from the first firing unit to the second firing unit or from the first firing unit to the first firing unit, And a blocking unit for selectively blocking the signal.

The flue extends from the connecting portion and the other side communicates with an exhaust hole formed at one side of the second fired portion so as to exhaust the heat inside the second fired portion and a flue Shaped discharge portion may be provided.

The blocking portion may include a communication hole disposed in the connection portion and communicating with the connection portion, or a door that selectively blocks the communication hole communicated with the connection portion of the second fired portion.

The double structure kiln according to the present invention can simultaneously perform the chaebol and chrysolite ceramics in the plurality of firing parts. Therefore, the productivity of the ceramics can be improved, the heat loss and the waste of resources can be reduced, and the emission amount of the pollution gas can be reduced, thereby preventing environmental pollution.
