The present invention relates to an improved traditional firewood kiln for firing ceramics. More specifically, the present invention relates to an improved firewood kiln for firing ceramics, and more particularly, to a firewood kiln for fire- It is possible to reduce the fuel (firewood) by shortening the heating time of the kiln and to reduce the amount of fuel used in the closure of the kiln entrance Which can prevent the generation of waste, enlarge the entrance door to enable the production of large ceramics, and improve the completion rate of artwork and the durability of the kiln by preventing cold waves, and to an improved kiln for firing ceramics.

Generally, the ceramics manufacturing process is made through the processes such as preparation of pottery, molding of pottery products, drying, grating, syrup, and chrysanthemum roasting.

In the above process, the soil is prepared by finely crushing the ground such as clay or sato, filtering off the impurities by sieving, precipitating in the water, collecting only fine sediments, and drying in shade for a certain period of time.

In addition, the molding is carried out using a method such as spinning, injection molding, extrusion molding, or compression molding, and is a process of making a predetermined bowl or work shape. Drying is a process of sufficiently drying the molded semi-finished product in the shade, I do a poem which inscribes the pattern of semi-finished goods.

The fully dried semi-finished product as described above is loaded on a kiln, baked and baked, and then a milk or vegetable is put on the unglazed product by applying a glaze or glaze to the glaze, and then decorated with a predetermined pattern. Then, And a temperature of about 1300 ° C is maintained for about 20 to 30 hours to roast a chaebol.

In the process of making such ceramics, the process of burning ceramics has been traditionally used for firewood kilns using wood fire. The conventional firewood kiln has been divided into a firing box connected to a plurality of fences, Lt; / RTI > In order to raise the temperature of the kiln to 1250 ~ 1300 ℃, the porcelain manufacturing process is to prepare the porcelain ware, form the porcelain product, and then dry the porcelain product, Roasting, and the like.

In the above process, the soil is prepared by finely crushing the ground such as clay or sato, filtering off the impurities by sieving, precipitating in the water, collecting only fine sediments, and drying in shade for a certain period of time.

In addition, the molding is carried out using a method such as spinning, injection molding, extrusion molding, or compression molding, and is a process of making a predetermined bowl or work shape. Drying is a process of sufficiently drying the molded semi-finished product in the shade, I do a poem which inscribes the pattern of semi-finished goods.

The fully dried semi-finished product as described above is stacked on a kiln and baked, followed by baking and glazing to the unglazed product, followed by a vegetable and a vegetable to decorate the predetermined pattern, I do.

The roasted chaebol varies depending on the type of ceramics. For example, roasted chrysanthemums roast at 1220-1250 ℃, celadon roots at 1250-1280 ℃ and white rods at 1280-1300 ℃.

In the process of making such ceramics, the process of burning ceramics has been traditionally used for firewood kilns using wood fire. The conventional firewood kiln has been divided into a firing box connected to a plurality of fences, Lt; / RTI > In order to preheat the kiln, it is necessary to have 8 ~ 10 hours of powder blast furnace, 10 ~ 12 hours of celadon and 14 ~ 15 hours of white porcelain depending on the difference of the firing temperature of ceramics. There is a difference depending on the size and the like.

The firing kiln is a kiln that fires ceramics. The firing kiln forms a round kiln by using soil and bricks. Then, the porcelain which is to be fired is injected into the inside of the kiln (firing box) The inside of the kiln is covered with firewood and the entrance of the kiln is covered with soil or refractory bricks so that the firewood can not escape out and the ceramics are burned.

During the firing process, cracks occur in the kiln due to expansion of the kiln due to the high temperature and high pressure inside the ceramics, and these cracks must be poured into the clay soil during firing. It is difficult to control the internal temperature of the kiln due to heat loss, It is often the case that cold air enters the interior through cracks and chilled waves occur in the ceramics.

When the ceramics are finished, the kiln is cooled, and then the opening that blocks the front of the kiln is broken. Then, the porcelain is taken to the broken entrance side, and the baked porcelain is removed again to the entrance side.

As described above, in the traditional firewood kiln, the ceramics are fired by the firewood, so that the materials of the pottery are combined with the gentle light that is generated when the soil and the soil are heated by the fire and burned, However, in order to utilize the firewood kiln as described above, there is a problem that a worker carries a porcelain every time with a narrow entrance, so that the porcelain must be drawn into or pulled out from the inside of the kiln. Further, since the entrance is formed narrowly, And the industrial waste such as soil that closes the entrance is continuously generated and causes environmental pollution. In addition, since it is necessary to perform the operation to block or re-open the entrance of the kiln, There is a falling problem.

Also, since the kiln is installed on the soil, the refractory bricks are disintegrated by the moisture generated from the soil or the soil, or the water that is normally open at the entrance, which shortens the durability of the kiln.

Also, since the temperature of the kiln should be checked while observing the color of the flame inside the furnace during the firing time, it is difficult to control the temperature, the cracks are generated in the kiln due to the internal pressure and the expansion due to the high temperature, There is a problem that the degree of completeness is reduced to such a degree as not to exceed 10 to 20% due to failure of temperature control and heat loss due to cracking and breakage of ceramics due to intrusion of cold air during cooling.

In order to solve the inconvenience of the conventional firewood kiln, a gas kiln or an electric kiln is widely used and used. Such a gas kiln or electric kiln has a large kiln, and a door for opening and closing the entrance of the kiln is installed It is expected that the effect of improving the workability can be expected. However, it is disadvantageous that various types of pottery can not be used when the pottery is burned using the gas kiln or electric kiln.

Therefore, it is necessary to develop a traditional firewood kiln that can burn ceramics more conveniently in burning pottery using a traditional firewood kiln that can obtain a beautiful color when the material of the pottery is baked by the firewood.

In order to solve the above problems, in the Utility Model Registration No. 20-0430334, a cavity 20 is provided between the barrel 10 and the firing chamber 30, and the cavity serves as a second barrel, Is known as a kiln for firing ceramics capable of shortening the preheating time and reducing fuel consumption.

In addition, Japanese Patent Registration No. 10-1122522 discloses a firewood kiln in which a support protrusion is formed on a mandrel to improve heat transfer efficiency.

The kilns are seen as a kiln for baking the sowing machine, considering the preheating time and the like.

However, the above-mentioned traditional kilns have a merit that they are made of only two bridges or that the firepower is increased by helping the burning of the firewood of the brassiere, there is still a limit to the prevention of waste generation and durability of the conventional firewood kiln and improvement of productivity and completion rate of excellent ceramics .
