In the kiln, the firewood inlet 111 is formed in the barrel 110; a plurality of firing compartments (120, 121, 122, 123) in which an entrance door 130 having a firewood inlet 131 formed therein is installed in the entrance and a fire viewing hole 140 is formed; A semi-elliptical hollow space 124 having a streamlined inner wall surface for guiding the fire to flow without a vortex into the stack; a stack 125' connected to the empty compartment 124; a chimney 126' connected to the stack 125; a plurality of slits (150) forming a passage through which fire passes between the bontong (110) and the plurality of firing compartments (120, 121, 122, 123); and a multi-stage pipe device 300 embedded in the foundation and supplying the fire generated by preheating of the rod tube 110 to the plurality of firing compartments 120, 121, 122, and 123 by minimizing heat loss. It relates to a wood-burning kiln for firing pottery of a wood-saving type for burning the main fire of the firing chamber.

In general, the ceramic manufacturing process is manufactured through processes such as preparing small earth, molding a ceramic product, and drying, unglazed, glazed, and chaebol-grilled.

In the above, the small soil preparation process consists of finely pulverizing small soil such as clay or sand, removing impurities through a sieve, precipitating it in water, collecting only fine sediment, and drying in the shade for a certain period of time.

In addition, molding is made using methods such as wheel molding, injection molding, extrusion molding, and 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, and In some cases, poems are engraved on semi-finished products.

The semi-finished product that has been sufficiently dried as described above is unglazed by loading it in a kiln and baking, and after applying glaze to the unglazed product or glazing to decorate a predetermined pattern and veggie, load it back into the kiln for about 1250~ The chaebol grilling is performed by maintaining a temperature of about 1300°C for about 20 to 30 hours.

Chaebol-grilling differs depending on the type of pottery, for example, buncheong porcelain at 1220~1250℃, celadon at 1250~1280℃, and white porcelain at 1280~1300℃.

In the process of making such pottery, the work of firing pottery has traditionally been used in a wood-fired kiln since ancient times. is connected with Bongtong preheats the entire kiln. For preheating of the kiln, 8 to 10 hours for Buncheong porcelain, 10 to 12 hours for celadon, and 14 to 15 hours for white porcelain are required depending on the difference in the firing temperature of the pottery. There is a difference depending on the size, etc.

The firing kiln is a kiln that fires pottery, and the firewood kiln uses soil and bricks to form a round kiln, then inserts the pottery to be fired into the inside of the kiln (firing compartment), preheats the kiln by means of a kiln, and then re-heats the kiln. A wood fire is built inside the kiln, and the entrance of the kiln is blocked with earth or fire bricks to prevent the wood fire from escaping, and the pottery is fired.

During this firing process, cracks occur in the kiln due to the expansion of the kiln due to high temperature and high pressure during the firing process, and these cracks must be filled with loess soil during firing. There were also cases in which cold air penetrated inside through cracks and caused a cold wave of ceramics.

When the firing of ceramics is completed, after the kiln is cooled, the entrance blocking the front of the kiln is broken, then goes into the broken entrance and takes out the baked ceramics back to the entrance, thereby completing the firing of ceramics.

As described above, in the traditional wood-burning kiln of the prior art, as the ceramics are fired by the wood fire, the material of the ceramics mixes with the earth component and the subtle light that appears when the soil is heated and baked in a wood fire, making the colors of ceramic bowls beautiful. However, in order to use the wood-burning kiln as described above, it is inconvenient that the worker has to transport the pottery one by one through a narrow entrance to insert or withdraw the pottery into or out of the kiln. It is impossible to work, and industrial waste such as soil that closes the entrance is continuously generated, causing environmental pollution. There is a problem with falling.

In addition, by installing the kiln on the soil as it is, there is a problem in that the refractory bricks disintegrate due to ground subsidence, moisture generated from the soil, or moisture mixed in when the entrance is normally opened, thereby shortening the durability of the kiln.

In addition, it is difficult to control the temperature because the temperature condition of the kiln must be checked while watching the color of the flame inside during the firing time. There is a problem in that the degree of completeness is significantly reduced to the extent of not exceeding 10 to 20% due to heat loss due to failure of temperature control and cracking, and damage to ceramics due to intrusion of cold air during cooling.

Due to these problems, gas kilns or electric kilns are widely used and widely used to solve the inconvenience of the above-mentioned traditional firewood kilns. The effect of improving workability can be expected because large-scale ceramics or mass production is possible, but there is a disadvantage that various thixotropes of ceramics are impossible when ceramics are baked using such a gas or electric kiln.

Therefore, it is necessary to develop a traditional firewood kiln that can burn ceramics more conveniently in firing ceramics using a traditional firewood kiln that can obtain the beautiful color that appears when the ceramic material is burned by a wood fire.

In order to improve the above problems, in Utility Model Registration No. 20-0430334, as shown in FIGS. 1 and 2, an empty space 20 is installed between the stick tube 10 and the firing chamber 30, A firewood kiln for porcelain firing is known, in which the kiln serves as the second kiln, and the two kilns preheat the kiln to shorten the preheating time and save fuel.

Also, in Patent Registration No. 10-1122522, there is known a wood kiln that improves heat transfer efficiency by forming a support protrusion on a rod barrel.

In consideration of the preheating time, the above kilns appear to be kilns for baking Buncheong porcelain.

However, the above traditional kilns simply have two kilns or have a configuration to increase thermal power by helping the burning of bonfires in the kilns. .

Therefore, in order to overcome the problems of the prior art, in Patent Registration No. 10-1457987 (October 29, 2014), as shown in FIGS. In the firewood kiln 100 for firing ceramics, the firewood inlet 111 that moves up and down is formed, the barbong 110; a plurality of firing compartments 120, 121, 122, 123 provided with a heat-resistant door 130 formed of iron ; An oval hollow 124 in which the fire control flow wall 170 is formed; and the roof of the wood kiln, a fire brick layer 200 is stacked, a glass fiber layer 201 is covered thereon, and then a fire earth layer 204 ) is sequentially formed, bound with a wire 202 , and covered with a loess layer 203 on the outside to provide a “firewood kiln for firing ceramics”.

The firewood kiln for firing ceramics of the prior Patent Registration No. 10-1457987 has a fire door at the entrance of the conventional firewood kiln, a vertical opening and closing sliding door at the entrance of the bontong, a pressure control means and a thermometer in each firing compartment, and at the same time, the base is made of reinforced concrete and formed in a configuration to prevent heat insulation and expansion on the ceiling wall of the kiln, reducing the heating time of the entire kiln by half compared to the existing firewood kiln, considering the difficulty of finding red pine in recent years This has the advantage of reducing fuel by less than half, and has the advantage of increasing the utility of the firewood kiln by improving the durability of the kiln and the completeness of ceramics to more than 90% As it is delivered to the compartment in turn, the upper firing compartment loses more heat than the lower firing compartment. At this time, there was a problem in that the more the firing compartment located at the top, the more firewood needed for the main fire was put in than the firing compartment located at the bottom.

In addition, the firewood kiln for firing ceramics of the above prior Patent Registration No. 10-1457987 is adjacent to the firing compartment 123 located at the uppermost side of the stack and the chimney in the upper central portion of the empty compartment 124 located above the kiln. Also, by installing the fire flow control wall 170 in the upper central part of the empty compartment 124, the length of the flow of fire in each firing compartment until it exits to the stack 125 and the chimney 126 is uniformly Although it has the advantage of maintaining the same temperature in the firing compartment by adjusting it to keep the quality of ceramics constant, the time for the fire to stay in the empty compartment 124 is relatively short, so There was a problem in that the leakage of firearms in the firing chamber and heat loss occurred accordingly, and this had an effect on the deterioration of the quality of ceramics.

In addition, in the above conventional firewood kiln for firing ceramics of Patent No. 10-1457987, a fire hole 140 through which you can check the state and temperature of the object being fired is penetrated and formed in the sidewall of each firing compartment, like this Since the fire opening 140 is formed through the sidewall of each firing compartment, there is a risk that fire in the firing compartment may leak to the outside through the fire viewing hole 140 , but also adversely affect the eye health of a person who visually checks it. can affect
