Description

Charcoal manufacturing equipment {APPARATUS FOR MANUFACTURING CHACOAL}

The present invention relates to an apparatus for manufacturing charcoal, and more particularly, to an apparatus capable of easily manufacturing charcoal using a mobile cart.

Charcoal is a solid product produced by heating wood while the air supply is blocked, and charcoal is characterized by being made of porous and carbon. During the process of making charcoal from wood, numerous fine pores are created in the charcoal, and when wood is made of charcoal, its components are converted to carbon. 75% to 85% of black coal, 85 to 95% of white coal is composed of carbon. Thus, charcoal is not only fuel, but also has many ways to utilize humidity control, odor removal, radioactive material absorption, antiseptic effect, water purification effect, electromagnetic shielding, and anion emission.

In Korea, 63.7% of the country is made of mountains, and among the OECD countries, Finland (73.9%), Japan (68.2%), and Sweden (67.1%) have the fourth largest forestry rate. Despite the efforts to overcome the current status of the domestic timber industry, such as 85% dependence on imports of foreign timber from China and India, and a low utilization rate of domestic timber, the dependence on imported timber remains unchanged. In fact, domestic wood is only used as chips for products of large companies with low value.

In addition, the current domestic charcoal market is over 50,000 tons per year, exceeding 100 billion won. Domestic production is about 7,000 tons, and imports of 43,200 tons from China, Vietnam, Laos, Russia, Indonesia, etc., also depend on 85% of foreign charcoal imports. On the surface, charcoal imports from China are banned, but large quantities are being imported into Yuyamuya, and the domestic charcoal market has been heavily influenced by China's will, and consumer prices have doubled in the last three years. In addition, low-cost charcoal is imported recently, and there are also words that "burning charcoal with imported charcoal causes cancer". Consumers know that domestic white coal is good if possible, but they prefer imported products because of unit price.

5 is a view showing the heat and exhaust state of the kiln and the kiln shown in FIG. 1, and FIG. 6 is a view showing the cooling box installed in the movable kiln shown in FIG. 7 is a photograph showing wood and charcoal used in the charcoal manufacturing method according to an embodiment of the present invention. Hereinafter, a method of manufacturing charcoal with reference to FIGS. 5 to 7 will be described below.

First, as shown in FIG. 7, wood (for example, oak), which is a raw material of charcoal, is cut into a cylindrical shape of 15 to 25 cm, and the cut wood is loaded onto the mobile truck 20. At this time, it is preferable that the wood is dried for about 3 weeks to reduce moisture. As described above, in the state in which the passage 21 of the movable cart 20 is opened, when the wood is started to be loaded from the inside of the passage 21, and the load proceeds considerably, the passage 21 is refractory brick 21a, etc. After closing with the load of the remaining wood to fill the interior of the mobile cart (20). This is to minimize the air present in the inside of the kiln 10, in a state where the movable bogie 20 is drawn inside the kiln 10 (hence, the depth according to the left and right width of the kiln 10 or the incoming direction, And the height is preferably as close as possible to the inner space of the kiln 10).

When the movable cart 20 is completely drawn into the inside of the kiln 10, the supply of air is blocked by completely blocking the inside of the kiln 10 from the outside by closing the open front surface of the kiln 10 with bricks and ocher. (However, the kiln hot air balloon 14 and kiln exhaust port 13, the communication 30 and the inlet passage 16 are open)

Subsequently, when heat is generated by burning firewood loaded in the entrance passage 16 of the arch, heat is supplied to the wood through the bogie hot air balloon 24, and the internal temperature of the kiln 10 is 800-900 degrees. Lasts until. At this time, since the inside of the kiln 10 is not supplied with oxygen in a blocked state from the outside, the wood is heated through heat, but does not burn, and 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 generated by thermal decomposition of wood, are generated and discharged through the kiln exhaust port 13 and the communication pipe 30. At this time, volatile hydrogen and oxygen are blown away, leaving only carbon, and carbonization means a phenomenon in which carbon compounds are thermally decomposed to generate carbon.

When the internal temperature of the kiln 10 reaches a desired temperature, the hot air supply is stopped, and the inlet 16a and the communication pipe 30 are 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 can maintain a high temperature and high pressure state.

Thereafter, when the internal temperature of the kiln 10 is about 400 degrees by natural cooling, the front surface of the movable cart 20 is opened, and the movable cart 20 is withdrawn from the kiln 10. At this time, when the cart 20 is withdrawn from the kiln 10, since the wood is supplied with oxygen through the air, the raw wood is ignited and burned. For reference, since the natural ignition temperature of wood is about 270 degrees, when oxygen is supplied, the wood can ignite naturally.

Thereafter, the movable cart 20 is covered by the cooling box 40 to block the inside of the movable cart 20 from the outside. Wood is spontaneously ignited in the process of covering the cooling box 40 (about 30 minutes to 1 hour) after the mobile cart 20 is withdrawn from the kiln 10, and oxygen supply is blocked after covering the cooling box 40 Is digested The cooling box 40 has a cap (cap) shape in which the lower part is opened and the upper, front, rear, and side parts are closed, and as illustrated in FIG. 6, the cooling box 40 is cooled in a state where the mobile box 20 is covered. Since the lower end of the box 40 is in a state in contact with the ground, oxygen supply to the wood is blocked. In this state, when naturally cooled to a room temperature level, the cooling box 40 is removed and charcoal generated from the raw wood is recovered. At this time, the charcoal becomes white charcoal, 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 surface of the movable cart 20 is opened, and the movable cart 20 can be withdrawn from the kiln 10, in which case the raw wood is black charcoal (or gumtan) ).

For reference, the conventional charcoal manufacturing method used to produce the charcoal without cutting the lumbered timber but without cutting it, and cut the prepared charcoal to a size suitable for actual use through a blade made of diamond. However, in this case, there is a problem that a large portion is lost due to the inherent brittleness of the charcoal, but in the case of the conventional charcoal manufacturing method, there is an inevitable situation such as the worker directly withdraws the produced charcoal from the kiln, so that the charcoal is cut in the cut state. It could not be produced.

However, according to the above, since the movable bogie 20 is used in the process of loading the raw wood and drawing out the manufactured charcoal, it is possible to manufacture the charcoal using the cut wood, thereby cutting the charcoal. You can easily solve the missing problem.

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