Generally, wood-fired kilns are known to be used for baking ceramics. However, ceramics and porcelain moldings, such as ceramics, are dried in the shade with clay or kaolin, and then dried in a shade. It is not easy to control the temperature because it is baked by heating and baking at a high temperature of ℃ or higher, there is a disadvantage that is not suitable when baking ceramics for the purpose of mass production.

In recent years, the use of electric kilns equipped with electric heaters for easy temperature control or gas kilns by gas burners tends to burn ceramics. In the case of gas kilns, the cost of fuel is usually high. Is more common to use

In a conventional gas kiln, ceramics charged into a firing chamber in a kiln body are fired to a desired temperature by using combustion heat generated by burning combustible gas.

In order to maintain the temperature of the firing chamber at a high temperature, such a gas kiln is usually provided with a gas combustion device such as a burner at both sides of the lower part of the firing chamber of the gas kiln body, and the combustion gas is provided through a nozzle installed in the crater under the firing chamber where the ceramic molding is charged. The porcelain molded product was charged to a firing chamber by firing at a predetermined temperature to produce porcelain.

In addition, electric kilns are generally generated from the case body, the fireproof material with heating wires built into the wall inside the body, the insulation inserted between the body and the fireproof material, and the control box and heat wires installed on the upper surface to control the temperature of the heating wire. It consists of a cover of a ceramic board which prevents heat from escaping to the outside.

The conventional 'pellet-type fuel supply device' of the Patent No. 10-1529868 is to store pellets in the form of pellets, which are made by pulverizing combustible materials such as wood, in a hopper and pellets stored in the hopper. It is to be injected into the blow passage connected to the firebox and then to adjust the supply amount of the pellets supplied to the firebox according to the blowing amount supplied to the blower passage to prevent the backfire of the firebox and to significantly improve the combustion efficiency.

However, in the conventional 'pellet type fuel supply device', when the pellet is moved to the firebox by the blower pressure of the blower, the pellet dust is generated when the dust is combusted, and the dust does not enter the firebox and hopper along the pellet movement path. While reversing negatively, the problem of lowering the combustion efficiency occurs by interrupting the supply of pellets.

In addition, as the pellet dust spreads (leakage) to the outside, the surroundings are polluted, causing environmental problems, and there is a problem that the risk of safety accidents increases due to the risk of fire caused by dust.

In addition, there is a problem in that the dust is accumulated in the space between the pellets as the pellet dust is discharged back along the pellet supply passage to increase the frictional force between the pellet and the surface of the mobile passage to lower the pellet feed force to further reduce the combustion efficiency.

Quick response is possible.

As shown in FIG. 4, the adjustment plate 152 configured as described above has an end portion of the blow passage 123 formed at a lower side thereof when it is fixed to the rear by sliding it (see FIG. 4A). Blowing power supplied away from the (111) falls, the thermal power (fire) of the fire chamber (111) falls.

In this case, the external air does not go to the firebox 111, and the fire can be caught. In this case, it is utilized in a situation in which it is possible to reduce the firepower and maintain the fire.

In this case, the pellets are mixed with a lot of air, and the fire is maintained at a medium fire level, the smoke is slightly seen, and the fire is kept long.

On the contrary, when the adjustment plate 152 is fixed by sliding toward the firebox 111 (see FIG. 4B), the end of the air passage 123 is positioned in the firebox 111 while oxygen is in the firebox 111. It is supplied in large quantities so that the fire is strong and smoke is not generated.

Such a state of the firebox can be managed by adjusting the blowing amount of the blower 140 through the controller 180 by the temperature sensor 170 installed therein.

By configuring the temperature of the firebox 111 as described above easily and quickly, it is possible to bake pottery in a day or so by burning fired pottery or electric or gas kilns for several days. It is possible to improve dramatically.

On the other hand, the cyclone portion 160 is a circumferential direction of the dust inlet pipe 160a is bent at the end of the dust discharge pipe 121b so that the dust generated from the pellet fuel supplied from the hopper 130 is introduced Hollow upper barrel portion 161 which is installed in communication with each other, and is installed in communication with the lower end of the upper barrel portion 161 and the lower cone-shaped portion 162 of the hollow that becomes smaller in diameter from the upper side to the lower side, the lower cone type The dust storage tank 163 is installed in communication with the lower end of the upper portion 162 is discharged and stored with a large specific gravity falling down, and the dust is discharged while being installed in the central portion of the upper barrel portion 161 and light dust rises.

Subsequently, the dust rotated along the circumferential surface of the upper barrel portion 161 is continuously rotated along the lower cone-shaped portion 162 and the heavy dust having a large specific gravity is lowered into the dust storage tank 163 and discharged and stored. The small light dust rises and is discharged through the dust discharge pipe 164 provided in the upper barrel portion 161.

Here, the dust discharge pipe 164 is further provided with a filter 165 to filter out harmful dust to prevent environmental pollution.

The movement force of the pellet dust to the cyclone unit 160 is made by the blowing force of the blower 140. Part of the air discharged from the blower moves the pellets to the fire chamber 111, and part of the air moves the pellet dust through the fuel supply pipe 121 and the dust discharge pipe 121b to the cyclone unit 160. At this time, the pellet supply pipe 121a coupled to the fuel supply pipe 121 at an angle to the fuel supply pipe 121 is almost never discharged from the blower or rather a negative pressure is generated to promote the supply of the pellets, which is discharged air from the blower 140. This is because most of them move to the dust discharge pipe 121b due to the nature of going straight, and in the process of moving to suck the air of the pellet supply pipe 121a leads to the dust discharge pipe 121b. The pellet falling into the pellet supply pipe 121a does not move to the dust supply pipe 121b due to its own weight and is moved to the lower portion of the fuel supply pipe 121 to be moved to the firebox 111.

As described above, the present invention prevents environmental pollution by easily collecting dust generated from the pellet fuel through the cyclone unit 160 to prevent environmental pollution and prevent fire from splashing into pellet dust scattered, thereby improving safety. There is a number.
