As the industry develops and life becomes more and more popular, modern people are increasingly interested in environment and health, and by this trend, various eco-friendly building materials such as block, brick, and tile have been developed and used.

Among them, ceramic boards which have been plastic-molded using an inorganic material such as yellow soil have been used in recent years.

In recent years, a ceramic molding having charcoal formed therein to propose a far infrared ray emission effect, a deodorizing effect, and an antibacterial function, which is an effect inherent to char, has been proposed and used by forming charcoal in the ceramic molding.

The ceramic formed product having charcoal formed therein may be produced by mixing sawdust or wood powder with yellow clay, clay or sand, pressing it into a board, tile, brick or block, and firing it at a high temperature.

As described above, when a molded product obtained by mixing sawdust or wood powder with yellow clay, clay or sand is fired, the wood powder on the surface of the molded article is completely burned to form a ceramic layer, and the wood particles therein are carbonized in the firing process to form a char layer .

The ceramic board is manufactured by processing an inorganic material into a granule form, compressing it into a board form and then firing it. When the inorganic material is produced into a granular form, the size of the granule may be uneven, or the water content of the granule may be uneven The board is broken during the firing process or the dimension of the ceramic board produced due to the difference in the shrinkage ratio is not uniform.

For example, when the ceramic tiles are manufactured and attached to the wall continuously, if the dimensional stability of the tiles is not ensured, there arises a problem that gaps occur between the tiles or that the tiles are not aligned horizontally and vertically.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, the present invention will be described in detail with reference to preferred embodiments of the present invention and the accompanying drawings, wherein like reference numerals refer to like elements.

It is to be understood that when an element is referred to as being "comprising" another element in the description of the invention or in the claims, it is not to be construed as being limited to only that element, And the like.

As shown in FIG. 1, the charcoal layer 101 is formed inside the board 100 and the ceramic layer 101 is formed in the inside of the board 100 102 surrounds the char layer 101 and is used as a building material such as tile, brick or block.

The ceramic board having the charcoal formed therein as described above exhibits various beneficial functions such as humidity control, deodorization, far-infrared radiation, and the like of the char layer 101, and the outer appearance is good by the ceramic layer 102 on the outside, It has high hardness and strength and can be used as a building finishing material such as tile, brick or block.

The method of manufacturing the ceramic board having the charcoal as described above may further include a step of crushing the strand (S100), the mixing step (S120), the crushing step (S120), the hydrous step (S140), the moisture equalization step (S150) A granulating step S160, a board forming step S210, a drying step S220, a preheating step S230, a baking step S240, and a cooling step S250.

Among the above manufacturing methods, the steps of crushing the strand (S100), the mixing step (S120), the crushing step (S120), the hydrous step (S140), the water equalization step (S150), and the granule forming step (S160) (S210), the drying step (S220), the preheating step (S230), the baking step (S240), and the cooling step (S250) are steps of forming the mixture granules Is formed on the surface of the ceramic board.

Crushing ore S110 )

Clay, sand, and clay, which are the raw materials of the mixture for forming the board, are dried and crushed to a predetermined size.

Hwangto emits far infrared rays, promotes blood circulation in the body, has excellent air purifying and deodorizing effect, and has humidity control.

And the clay increases the viscosity of the mixture and increases the strength and durability of the produced ceramic molding.

It is possible to prevent the occurrence of cracks in the ceramic molding by further mixing the sandy soil and the clay and to produce a ceramic board with a white color on the outer surface, thereby producing a more beautiful ceramic board.

Mixing step ( S120 )

In the mixing step (S120), 10 to 50 parts by weight of clay and 1 to 30 parts by weight of sawdust are mixed with 10 to 80 parts by weight of loess.

10 to 80 parts by weight of the clay is mixed with 10 to 80 parts by weight of the clay. When the clay is mixed with less than 10 parts by weight, the mixture is weakly pressed and the press molding is not properly performed. When the clay is mixed with more than 50 parts by weight, Since the content of charcoal (wood flour) is reduced and it is difficult to obtain the effect of the loess and charcoal, 10 to 80 parts by weight of the loess is preferably mixed with 10 to 50 parts by weight of the clay.

The wood flour in the form of sawdust is mixed with 1 to 30 parts by weight per 10 to 80 parts by weight of the loess. When the wood is mixed with less than 1 part by weight, a char layer is not formed in the inside after the plastic working, and when the wood is mixed with more than 30 parts by weight, the press molding is not performed and the strength of the fired ceramic molding is lowered, It is preferable to mix 1 to 30 parts by weight of wood flour with respect to 10 to 80 parts by weight of the loess.

In addition, in the mixing step (S120), 20 to 40 parts by weight of sandy soil and 20 to 40 parts by weight of clay can be further mixed in addition to yellow loam, clay and wood powder.

The grinding step ( S130 )

After the mixing step (S120), the mixed mixture is milled to a size of 100 to 250 mesh by a ball mill (wet mix) to make it into a slip state, and then dried with a spray dryer to obtain powder state.

Singer steps ( S140 )

As shown in FIG. 2, the pulverized mixture particles are transferred to the hydrator 120 through the pulverization step (S130) to supply moisture to the mixture.

As shown in FIG. 2 and FIG. 3, the water mixer 120 is provided with a feed screw 126 which rotates by driving a motor in a pipe-shaped body 124 having an open top part.

The pulverized mixture particles are transported to the hydrator 120 through the grinding step S130 and then moved inside the body 124 through the transporting screw 126 to be discharged into the discharge port 125 at the end of the body 124, (130).

At this time, the water droplets continuously supplied through the openings on the upper part of the body 124 of the water mixer 120 fall down into the mixture powder during conveyance and are admixed to the mixture powder. Water is dropped from the tank 121 installed separately through the water supply pipe 122 through the nozzle 123 into the mixture in the water pipe 120 as shown in FIG.

It is preferable to configure a controller capable of controlling the amount and speed of water droplets falling from the nozzle 123 so that the amount of moisture adhering to the mixture can be adjusted.

Thereafter, as the transfer screw 126 rotates, the mixture is transferred through the body 121 of the water mixer 120 and stirred by the rotation of the transfer screw 126, so that the process of gradually equalizing the moisture of the mixture proceeds.

In order to press-mold the mixture into a board, and to perform a sintering process, the mixture must contain a predetermined amount or more of water. The mixture is added to the mixture through the water step (S140) to adjust moisture of the mixture.

It is not necessary to match the correct water content for the press molding and the plastic forming in the water step S140, and the water content is increased more than the water content of the required water content, and the correct water content is adjusted through the subsequent drying step S220.

Moisture equalization step ( S150 )

As shown in FIG. 2, the mixture admixed through the hydro-mixing step (S140) is conveyed to the roller-type presser 130 and is compressed.

When water droplets are continuously dropped on the powder mixture of the loess, clay, clay, clay, sand, and wood powder of the hydrator 120 in the hydrous step S140, the mixture particles are partially aggregated into a lump form by water droplets, exist.

As shown in FIG. 4, when a mixture of a part of a mixture and a part of a powder is compressed by a compression roller 130, the mixture is compressed into a small disk shape by a water droplet, Water is supplied to the neighboring mixture powder to distribute the moisture of the mixture more evenly.

It is possible to automatically mass-produce the granules producing the ceramic board through the water phase (S140) capable of continuous operation and the water equalization step (S150) capable of continuous operation, and the water phase (S140) and the moisture equalization step (S150), it is possible to reduce the drying time for equalizing the water content of the pre-fired ceramic board to a predetermined range, thereby drastically reducing the time required for manufacturing the ceramic.

Granulation step ( S160 )

The mixture composed of a small disk form and a powder form is introduced into the mixer 140 as shown in FIG. 2 through the moisture equalization step (S150) and stirred.

The mixer 140 rotates the stirring blade of the ribbon shape to agitate the mixture of the disk shape and the powder shape so that moisture in the mixture is more evenly distributed, and the powdery mixture is kneaded together.

The mixture stirred through the mixer 140 is transferred to the granulator 150 to form granules in the form of rounded granules.

5, a sieve 152 having a size of 3 mm is formed in a lower portion of the barrel 151, and a rotary blade 152 formed in a lower portion of the barrel 151 in a lower portion of the barrel 151, (154) are formed.

The mixture injected into the cylinder 151 of the granular molding machine 150 is rotated by the rotation of the motor (not shown) while the rotary vane 154 formed at the lower portion of the shaft 153 rotates, The granules having a particle size of 3 mm are discharged while the mixture is passed through the sieve 152.

Since the rotary vane 154 presses the mixture of the dough shape and the disk shape into the sieve 152 while rotating in a state of being in tight contact with the sieve 152 in an inclined form, .

Board molding step ( S210 )

Through the granule forming step (S160), the granulated powder mixture is press-molded in the form of a board through a press molding machine.

Drying step ( S220 )

The board formed through the board forming step (S210) is dried so that the water content of the board is 8 to 10% by weight. If the moisture content of the board is less than 8% by weight, the wood inside the fired ceramic board is completely burned and the charcoal of black color is not formed. Therefore, the object of the present invention can not be achieved. The board may be cracked due to the high temperature in the subsequent preheating step or the baking step, so that the water content of the board is dried to 8 to 10 wt% in the drying step (S220).

Further, during the drying step (S220), the moisture of the mixture constituting the board becomes uniform.

Preheat phase ( S230 )

The board is preheated to a temperature of 350 to 700 DEG C before the board having undergone the drying step (S220) is fired.

If the board is directly fired at a high temperature without the preheating step (S220), the board may be cracked due to a rapid temperature rise. Therefore, the board is preheated to a temperature of 350 to 700 ° C before firing.

Firing step ( S240 )

The preheated board is fired at a temperature of 700 to 1,300 DEG C for 3 to 13 minutes through the preheating step (S230). When the ceramic substrate is fired at a temperature of 700 to 1,300 ° C. for 3 to 13 minutes, the ceramic layer of the ceramic board is thinly formed to a thickness of 0.1 to 1 mm.

The ceramic board is composed of a char layer 101 and a ceramic layer 102 surrounding the char layer 101 as shown in FIG. 1. The thinner the thickness of the ceramic layer 102, the more effective is the char.

When the firing time is less than 3 minutes, the char layer 101 in the ceramic board 100 is not properly formed. If the firing time exceeds 13 minutes, the char is completely burned and the char layer can not be formed. The firing time is preferably 3 to 13 minutes.

Since the mixture particles of the ceramic board before the firing are uniformly functioning in water through the above-mentioned water step (S140), water equalization step (S150), and drying step (S160) Since the shrinkage ratio is shown, the dimensional stability is excellent.

Cooling phase ( S250 )

A cooling step of cooling the fired ceramic board through the firing step (S240) at room temperature is performed.

The ceramic board manufacturing equipment and charger manufacturing method in which the charcoal is formed in the internal structure of the present invention is configured such that the size and water content of the inorganic material granules, which are the materials for forming the ceramic board, are made constant so that the ceramic board is not broken , Dimensional stability can be ensured and a ceramic board of uniform size and quality can be manufactured.
