The present invention relates to a heating device made of charcoal used in various heating devices, dryers, melting furnaces, and the like. Heating element is required to generate heat directly

Conventionally, a material provided as a heating element is provided with nickel (Ni), chromium (Cr), tungsten (W), and molybdium (Mo). Among the above materials, nickel and chromium are up to 500 ° C, tungsten is 1200 ° C, Molybidium is known to have the ability to generate heat on the order of 1500-1700 ° C.

Conventionally, the above materials are used as a heating element of a device that requires heat generation. However, since all of the above materials are minerals, they are very expensive, which is a great factor to increase the price of the product using the heating element, and the resistance is not so low. Limitations apply to devices that require high temperature generation, such as furnaces.

The present invention has been made in view of the conventional problems as described above, and provides a heating device made of a heating element using charcoal which is not only extremely easy to manufacture but also extremely low in manufacturing cost and has a high temperature heating effect. .

11. Case

The heating device made of charcoal heating element provided in the present invention has a closed structure and a diaphragm and a hollow tube connected to each of the poles of the power supply, while being fixed near the both ends of the longitudinal direction in the case. (Iii) a heating element accommodating cylinder which has a shape and is fixed between both diaphragms in the case, a heating element manufactured by the manufacturing method and accommodated in the heating element accommodating space, and a current stabilizer accommodated between the heating element accommodating cylinder and the inner surface of the case. It is done.

Hereinafter, a specific embodiment of the present invention will be described in detail with reference to the drawings.

1 is a process chart of the heating element manufacturing method according to the present invention.

As the wood used in the charcoal extraction process (1) of the heating element manufacturing process according to the present invention, it is recommended that the oak or oyster oak or glacial vegetation used in the prior art to manufacture charcoal. This wood is put into a kiln and burned at 1700 ° C. for 4 days, and then taken out of the kiln, placed in a container and covered with ocher and quenched to obtain the charcoal required in the charcoal extraction process (1) of the present invention.

When the charcoal extraction process (1) is completed, a pulverization process (2) for grinding the charcoal to a predetermined size is performed.

The pulverizer used in the pulverization step 2 is selected and used in the conventionally widely used pulverizer, and its particle size is determined to a size suitable for the use of the heating element.

When the grinding step 2 is completed, a gas removal step 3 for removing residual gas in the char generated in the charcoal collection step 1 is performed. The gas removal step (3) is completed by injecting the charcoal obtained in the crushing step (2) into a vacuum heater, heating it to 1000 ° C with indirect heat in a vacuum state, and then opening the discharge hole of the vacuum heater to discharge the generated gas. .

When the gas removal step 3 is completed, a heat treatment step 4 is performed to convert the arrangement of the molecules forming the char into a structure having a low resistance value. The heat treatment step (4) is to repeat the process of heating the charcoal in which the gas removal step (3) is completed by vacuum for 1 hour a day in a vacuum state in the previous vacuum heater and then slowly cooled at room temperature.

When the above processes are completed, a heating element using charcoal according to the present invention having a resistance value of 0 to 10Ω can be obtained.

Figure 2 shows a cross-sectional view of the heat generating mechanism 10 using a heating element according to the present invention.

Reference numeral 11 is a case of a closed structure with a space formed therein.

The conductive diaphragm 12 is fixed to the both ends of the longitudinal direction in the case 11, and each pole of a power supply is connected to each diaphragm 12. As shown in FIG.

Between the diaphragms 12, the heat generating body accommodating body 13 which becomes hollow cylinder shape is fixed.

In the heat generating body accommodating body 13, the heat generating element 14 manufactured by the above-mentioned manufacturing method is accommodated.

In each of the above configurations, the case 11 uses a material having excellent heat conductivity and a non-conducting material, and the diaphragm 12 and the heating element receiving body 13 use a material having excellent conductivity and heat conductivity.

When each pole of the power source is connected to the diaphragm 12 of the heat generating mechanism 10 according to the present invention and the electricity is generated through the heating element 14, heat of 500 to 2000 ° C. is generated by the resistance of the heating element 14. Occurs. Here, the particles constituting the heating element 14 have a lot of voids, and the movement of ions is activated to generate an electric field, resulting in an unstable flow of current, but such an unstable current is caused by the current stabilizer 15 having excellent conductivity around the heating element 14. As it is offset, no problem occurs in the uniform exothermic action.

The heating element obtained by the present invention is made of wood, not minerals, and the manufacturing process is simple, so the manufacturing cost is extremely low and the heating element can be exerted higher than the existing heating element. It can be widely used as a heating element.

Therefore, the heating device made of a heating element using the charcoal of the present invention can be supplied at low cost as a heating means of various heating devices because its configuration is extremely simple.
