Description

Charcoal Making Equipment {APPARATUS FOR MANUFACTURING CHACOAL}

The present invention relates to a charcoal manufacturing apparatus, and more particularly to a device that can easily produce charcoal using a mobile cart.

Charcoal is a solid product produced by heating wood with air cut off. Charcoal is characterized by being porous and carbon. In the process of making charcoal from wood, there are numerous micropores in the char, and if the wood is charcoal, its components are converted to carbon. In the case of black coal, 75% to 85% of white coal is composed of 85% to 95% of carbon. Thus, in addition to fuel, charcoal has many ways to utilize humidity control, odor removal, radioactive material absorption, antiseptic effect, water purification effect, electromagnetic wave blocking and anion emission.

The country has 63.7% of the country is made up of mountains, has the fourth highest forest ratio after Finland (73.9%), Japan (68.2%), Sweden (67.1%) among OECD countries. Despite the efforts to overcome the current status of the domestic timber industry, such as 85% dependence on foreign timber imports from China and India and low utilization rate of domestic timber, the dependency on foreign imported timber remains unchanged. Indeed, domestic timber is being used as a chip for low-value large enterprise products.

In addition, the domestic charcoal market is over 50,000 billion tons per year. Domestic production is about 7,000 tons, and imports of 43,200 tons are imported from China, Vietnam, Laos, Russia, Indonesia, etc., and dependence on foreign charcoal imports is 85%. Apparently, the import of charcoal from China is banned, but a large amount is imported into Yuyamuya, and the domestic charcoal market is heavily influenced by China's will, and consumer prices have doubled in recent three years. In addition, inexpensive charcoal is recently imported, and the words "grilled with imported charcoal cause cancer." Consumers know that domestic white coal is as good as possible, but they prefer imports because of unit cost.

The side wall 25 has a passage 21 recessed from the upper end adjacent to the front wall 26a, and the passage 21 is located above the intermediate wall 27b, which will be described later. The worker can enter the inside of the trolley 20 through the passage 21 to load the wood, which is the raw material of charcoal, and when the loading proceeds considerably, the passage 21 is closed with a refractory brick 21a, and then the wood is closed. Fully loaded inside the trolley 20, the mobile trolley 20 is drawn into the kiln 10 in a state where the passage 21 is closed.

The side wall 25 has the trolley | bogie hot air balloon 24 which communicates with the kiln hot air balloon 14 in the retracted state, and the trolley | bogie exhaust port 23 which communicates with the kiln exhaust port 13 in the retracted state.

Auxiliary passage (29c) parallel to the () is formed.

FIG. 5 is a diagram illustrating a hot and exhaust state of the kiln and the sub-gun shown in FIG. 1, and FIG. 6 is a diagram illustrating a cooling box installed in the portable kiln shown in FIG. 1. Figure 7 is a picture showing the wood used in the charcoal manufacturing method and the charcoal prepared according to an embodiment of the present invention. Hereinafter, a method of manufacturing charcoal will be described with reference to FIGS. 5 to 7.

First, as shown in Figure 7, the wood (for example, oak) that is the raw material of charcoal is cut into a cylindrical shape of 15-25cm, and the cut wood is loaded on the mobile cart 20. At this time, the wood is preferably dried for about three weeks to reduce moisture. As described above, when the passage 21 of the mobile trolley 20 is opened, when the timber is started to be loaded from the inside of the passage 21 and the loading is considerably progressed, the passage 21 is refractory brick 21a or the like. After closing it to load the remaining wood to fill the inside of the mobile bogie 20. This is to minimize the air present in the kiln 10 in a state in which the mobile trolley 20 is introduced into the kiln 10 (thus, the depth according to the left and right widths or the pulling direction of the kiln 10, And the height is preferably as close as possible to the inner space of the kiln 10).

When the mobile trolley 20 is completely introduced into the kiln 10, the open front of the kiln 10 is closed with bricks and ocher to completely block the inside of the kiln 10 from the outside to block the supply of air. (The kiln hot air balloon 14 and the kiln exhaust port 13, the communication 30, and the inlet passage 16 are open.)

Subsequently, when the firewood loaded in the inlet passage 16 of the firewood is burned to generate heat, the heat is supplied to the wood through the bogie hot air balloon 24, and the heat is 800-900 degrees inside the kiln 10. Until it lasts. At this time, since the inside of the kiln 10 is not smoothly supplied with oxygen in the state of being blocked from the outside, the wood is heated through heat but does not burn, and is carbonized through high-temperature drying and other components of wood except carbon (for example, For example, gaseous components such as carbon monoxide, carbon dioxide, methane, hydrogen, and ethylene, which are gas components generated by pyrolysis of wood, are generated and discharged through the kiln exhaust port 13 and the communication 30. At this time, volatile hydrogen and oxygen fly away and only carbon remains, and carbonization refers to a phenomenon in which carbon is thermally decomposed to generate carbon.

When the internal temperature of the kiln 10 reaches the desired temperature, the hot air supply is stopped, and the communication 30 with the inlet 16a of the fungus is closed. The communication 30 may be closed through a separate valve (not shown) installed in the middle, and the inlet 16a may be closed through ocher or the like. This is to prevent the heat inside the kiln 10 from easily escaping to the outside, and the inside of the kiln 10 may maintain a high temperature and high pressure.

Thereafter, when the internal temperature of the kiln 10 is about 400 degrees by natural cooling, the front of the mobile trolley 20 is opened, and the mobile trolley 20 is withdrawn from the kiln 10. At this time, when the trolley 20 is pulled out from the kiln 10, since the wood is supplied with oxygen through air, the raw wood is ignited and combusted. For reference, since the spontaneous ignition temperature of the wood is about 270 degrees, the wood can spontaneously ignite when oxygen is supplied.

Subsequently, the inside of the movable trolley 20 is blocked again from the outside by covering the movable trolley 20 through the cooling box 40. Wood is spontaneously ignited in the process of covering the cooling box 40 after withdrawing the mobile cart 20 from the kiln 10 (about 30 minutes to 1 hour), and the oxygen supply is blocked after covering the cooling box 40. Digested. Cooling box 40 is a hat (cap) shape of the lower portion is opened, the top, front and rear and the side is closed, as shown in Figure 6, cooling the cooling box 40 in the state covered with the movable trolley 20 Since the bottom of the box 40 is in contact with the ground, the wood is cut off the oxygen supply. In this state, when naturally cooled to room temperature, the cooling box 40 is removed and the charcoal generated from the raw wood is recovered. At this time, charcoal becomes white coal, and carbonization occurs sufficiently to prevent generation of carbon monoxide during combustion.

On the other hand, after the internal temperature of the kiln 10 becomes 275 degrees, the front of the mobile trolley 20 can be opened, and the mobile trolley 20 can be withdrawn from the kiln 10. In this case, the raw wood is black coal (or gum charcoal). )

For reference, the conventional charcoal manufacturing method was used to produce charcoal without cutting in the state of removing the felled wood, the cut charcoal was cut to a size suitable for actual use through a diamond blade. However, in this case, there is a problem that many parts are lost due to the inherent brittleness of the charcoal, but in the case of the conventional charcoal manufacturing method, the charcoal is cut in a state in which it is inevitable such that the worker draws the charcoal directly from the kiln It could not be manufactured.

However, according to the above, since the mobile cart 20 is used in the process of loading the raw wood and withdrawing the manufactured charcoal, the charcoal may be manufactured using the cut wood, thereby cutting the charcoal. Problems that are lost can be easily solved.

Although the present invention has been described in detail with reference to preferred embodiments, other forms of embodiments are possible. Therefore, the spirit and scope of the claims set forth below are not limited to the preferred embodiments.
