Description

How to make charcoal {METHOD FOR MANUFACTURING CHARCOAL}

The present disclosure relates to charcoal and a method for producing charcoal.

In general, candles (candle) was used as a means to light up the darkness by lighting a wick, but recently, it is a trend that is often used for interior props to create a subtle atmosphere indoors. In this regard, Korean Patent Publication No. 10-2014829 discloses a technique for a candle wick.

However, since charcoal is inconvenient for ignition and the convenience of use is deteriorated since it takes a relatively large amount of time from the start of ignition until it is completely ignited compared to a general cotton wick, it has not been used as a wick for a candle.

Moreover, conventional candles are mainly used to create a subtle atmosphere indoors, but when soot is generated due to incomplete combustion of charcoal, it is not easy to burn charcoal indoors because there is a concern that the health of users may be impaired.

On the other hand, when the lump of charcoal is pulverized through mechanical processing (for example, a crushing process) to make the charcoal into a certain size, charcoal debris, which is a residue, is generated, but conventionally, a method of recycling it for fuel was not adequate. Therefore, there is a demand for the development of a new technology that improves the conventional problems.

The technical idea of the present disclosure is to solve the above-described problem, and an object thereof is to provide a technology for manufacturing a candle wick using charcoal.

In addition, the technical idea of the present disclosure has another object to provide a technology capable of manufacturing charcoal that is easy to ignite.

And, the technical idea of the present disclosure has another object to provide a technology for charcoal with less generation of soot during combustion.

In addition, the technical idea of the present disclosure is another object of providing a technology for crushing the charcoal lump and recycling the remaining charcoal shavings into a wick of a candle.

In addition, the technical idea of the present disclosure is another object of providing a technology for pulverizing a lump of charcoal and recycling the remaining charcoal flakes to form a fuel molded body.

The problem to be solved by the present invention is not limited to the above-described problem, and other technical problems that are not mentioned will be clearly understood by those of ordinary skill in the technical field to which the present invention belongs from the following description.

In order to achieve this object, as an embodiment of the present invention, a method for producing charcoal comprises: a binder mixing step of preparing a first mixture by mixing coal fine powder and a binder; Adding charcoal powder to make a second mixture by adding and mixing the charcoal powder to the first mixture; A wax addition step of adding and mixing wax powder to the second mixture to prepare a third mixture; A molding step of forming a charcoal body by molding the third mixture into a predetermined shape; And forming a capillary tube forming a capillary tube inside the charcoal body.

In addition, the charcoal powder may be made of charcoal having a diameter of 0.1mm or more to less than 0.6mm, and the charcoal powder may be prepared as charcoal having a diameter of 0.6mm or more to 1.5mm or less.

In addition, the binder may be provided as a mixture of water glass and water in a predetermined ratio.

In addition, in the step of forming a capillary tube, the wax contained in the charcoal body is vaporized and selectively removed, thereby forming a capillary tube inside the charcoal body.

In addition, the method for producing charcoal comprises a water addition step of adding water to the third mixture; An immersion step of immersing the charcoal body in a molten wax solution; And a drying step of removing and drying the charcoal body from the wax solution.

And, in the wax addition step, the diameter of the wax powder may be provided in the 0.8 ~ 1.8mm.

In addition, in the wax addition step, the content of the wax powder may be provided in an amount of 0.8 to 1.4 parts by weight based on 10 parts by weight of the charcoal powder.

As another embodiment of the present invention to achieve this object, charcoal may be prepared by the above-described manufacturing method.

The means for solving the above-described problems are merely exemplary and should not be construed as limiting the present invention. In addition to the above-described exemplary embodiments, there may be additional embodiments described in the drawings and detailed description of the invention.

As described above, according to various embodiments of the present invention, even if the wick of a candle is manufactured using charcoal, it is easy to ignite, so that convenience in use is improved, and there is little generation of soot during combustion, so that it can be used indoors.

And, the charcoal wick manufactured using charcoal can be formed to have a flame size relatively larger than that of a general candle when burning, and can create a natural and romantic atmosphere indoors like a bonfire is burning, and it is cozy and It provides a visual effect of a warm feeling.

In addition, since the charcoal lump can be pulverized and the remaining charcoal crumbs can be manufactured with at least one of a wick for a candle and a molded body for fuel, there is an effect that the charcoal crumbs can be recycled.

In addition, since the charcoal body can be manufactured in various shapes during molding, it is possible to implement various types of candle wicks intended by the user, and can be manufactured as interior props related to flames.

Effects according to various embodiments of the present invention are not limited to the above-mentioned effects, and other effects that are not mentioned will be clearly understood by those skilled in the art from the description of the claims.

Preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings, but technical parts that are already well-known will be omitted or compressed for conciseness of description.

It should be noted that references to "one" or "one" embodiment of the present invention in this specification are not necessarily to the same embodiment, and they mean at least one.

In the following embodiments, terms such as first and second are not used in a limiting meaning, but are used for the purpose of distinguishing one component from another component.

In the following examples, expressions in the singular include plural expressions unless the context clearly indicates otherwise.

In the following embodiments, terms such as include or have means that the features or components described in the specification are present, and do not preclude the possibility that one or more other features or components may be added.

When a certain embodiment can be implemented differently, a specific process order may be performed differently from the described order. For example, two processes described in succession may be performed substantially simultaneously, or may be performed in an order opposite to the described order. That is, each step of the method described in the present specification may be appropriately performed in any order unless otherwise stated in the specification or clearly contradicted by context.

1 is a flowchart schematically showing a method of manufacturing charcoal according to an embodiment of the present invention. Referring to FIG. 1, a method of manufacturing charcoal according to an embodiment may include a binder mixing step, a charcoal powder addition step, a wax addition step, a water addition step, a shaping step, a capillary formation step, an immersion step, and a drying step.

In the binder mixing step (S101) according to an embodiment, a first mixture may be prepared by mixing charcoal fine powder and a binder. Here, the binder is a mixture of water glass and water in a certain ratio. For example, water glass and water may be mixed in a weight ratio of 7:3 to 8:2 to be prepared as a binder. In addition, in one embodiment, the charcoal powder may be prepared as charcoal having a diameter of 0.1mm or more to less than 0.6mm. If the diameter of the charcoal powder is smaller than 0.1mm, fine powder may be scattered and workability may be deteriorated, and there is a concern that the charcoal ignition may not be smoothly performed. When the charcoal fine powder is mixed with the binder in the binder mixing step S101, a binder coating film may be formed on the surface of the charcoal fine powder. The charcoal powder on which the binder coating film is formed may enter the gaps of the charcoal powders during the step of adding the charcoal powder (S102), which will be described later, to adhere the charcoal powders.

In the step of adding the charcoal coarse powder according to an embodiment (S102), a second mixture may be prepared by adding and mixing the charcoal coarse powder to the first mixture made in step S101. In one embodiment, the charcoal powder may be prepared from charcoal having a diameter of 0.6mm or more and 1.5mm or less. When the diameter of the charcoal powder is larger than 1.5mm, compression is not smoothly performed during the molding step (S105) to be described later, so that the charcoal powder easily falls from the charcoal body, and aesthetics and workability may be deteriorated.

In the wax adding step (S103) according to an embodiment, a third mixture may be prepared by adding and mixing wax powder to the second mixture prepared in step S102. In one embodiment, the wax may be applied to at least one of natural wax (eg, soy wax, bees wax, palm wax, etc.) and artificial wax (eg, paraffin wax, gel wax, etc.). In addition, in one embodiment, the diameter of the wax powder may be provided in the 0.8 ~ 1.8mm.

As a specific example, the diameter of the wax powder may be 0.8mm, 0.9mm, 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm or 1.8mm. In addition, the diameter of the wax powder may be in the range of one or more of the above values and one or less of the above values.

For example, the diameter range of the wax powder is 0.8mm to 1.1mm, 1mm to 1.3mm, 1.1mm to 1.4mm, 1.2mm to 1.5mm, 1.3mm to 1.6mm, 1.4mm to 1.7mm, 1.5mm to 1.8mm Alternatively, it may be provided in the range of 1mm to 1.8mm. The wax powder according to an embodiment shortens the ignition time of charcoal within the above diameter range, minimizes the generation of soot during combustion, and enables stable combustion without extinguishing the fire during the duration of combustion.

If the diameter of the wax powder is less than 0.8mm, the formation of a capillary tube inside the charcoal body is not smooth in the capillary formation step to be described later, so it is not easy to ignite the charcoal, there is inconvenience in use, and there is a possibility that soot may occur during combustion. It can be easily extinguished after the charcoal is on fire. In addition, when the diameter of the wax powder exceeds 1.8 mm, the diameter of the capillary tube formed inside the charcoal body becomes excessively large in the capillary formation step to be described later, making it difficult to perform the function as a wick (or a molded body for fuel), and is stable. Since there is a concern that combustion may become difficult, the diameter of the wax powder is preferably applied within the above-described range.

In addition, in an embodiment, the content of the wax powder may be provided in an amount of 0.8 to 1.4 parts by weight based on 10 parts by weight of the coarse charcoal powder. As a specific example, based on 10 parts by weight of the charcoal powder, the content of the wax powder may be provided in 0.8 parts by weight, 0.9 parts by weight, 1 part by weight, 1.1 parts by weight, 1.2 parts by weight, 1.3 parts by weight, or 1.4 parts by weight. . In addition, the content of the wax powder may be in the range of one or more of the above values and one or less of the above values.

For example, the content range of the wax powder may be provided in the range of 0.8 parts by weight to 1.2 parts by weight, 0.9 parts by weight to 1.3 parts by weight, 1 part by weight to 1.4 parts by weight, or 0.8 parts by weight to 1.4 parts by weight. The wax powder according to an embodiment shortens the ignition time of charcoal within the above content range, minimizes the occurrence of soot during combustion, and helps to achieve stable combustion without extinguishing the fire during the duration of the combustion.

If the content of the wax powder is less than 0.8 parts by weight, the formation of a capillary tube inside the charcoal body is not smooth in the capillary tube formation step to be described later, so it is not easy to ignite the charcoal, there is inconvenience in use, and soot may occur during combustion. It can be easily extinguished after the charcoal is on fire. In addition, when the content of the wax powder exceeds 1.4 parts by weight, the diameter of the capillary tube formed inside the charcoal body in the capillary tube formation step to be described later becomes excessively large, making it difficult to perform the function as a wick (or a molded body for fuel), and for a long time. It is preferable that the content of the wax powder is applied within the above-described range because stable combustion during the period is difficult.

According to an embodiment, in the water adding step (S104), water may be added in a certain amount (eg, 2 to 3 g) to the third mixture made in step S103, and the dough may be mixed. In addition, depending on the implementation, the water addition step (S104) may be omitted. For example, when the moisture content of the third mixture is higher than a certain level, the step of adding water (S104) may be omitted and the process may proceed to the step (S105).

In the molding step (S105) according to an embodiment, the third mixture may be molded into a certain shape to form a charcoal body. According to one embodiment, in the forming step (S105), a third mixture is introduced into a mold having a certain shape (for example, a square pillar shape), and pressurized with a press pressure of 200 to 300 kg/cm ² for 3 to 4 seconds to form a square pillar. You can make a shaped body. In addition, depending on the implementation, it is also possible to shape the charcoal body into various shapes by applying various shapes of the mold used in the forming step (S105).

In the capillary forming step S106 according to an embodiment, a capillary tube may be formed in the char body made in step S105. According to one embodiment, in the capillary tube formation step (S106), the charcoal body is put into an oven and heat-treated at a temperature of 100 to 200°C for 10 to 30 minutes to selectively vaporize the wax component contained in the charcoal body. By removing it, a capillary tube can be formed inside the charcoal body. 2 is a conceptual diagram schematically showing the exterior and interior of charcoal according to an embodiment of the present invention. 2, the wax powder mixed with the charcoal coarse powder 100 and the charcoal fine powder 200 is vaporized by high temperature during the capillary formation step (S106) and removed from the charcoal body 10, so that the space where the wax powder was As it is emptied, the capillary tube 300 having a narrow and long shape may be formed. In addition, as the binder is thermally cured in the capillary forming step (S106), the charcoal body 10 is hardened and has impact resistance that is not easily broken by an external impact.

In the immersion step S107 according to an embodiment, the charcoal body 10 having a capillary tube formed in step S106 may be immersed in a solution of molten wax (eg, natural wax, artificial wax, etc.) for 2 to 10 minutes. In the immersion step (S107), some of the wax solution permeates the inside of the charcoal body 10, and another part of the wax solution may be coated on the outer surface of the charcoal body 10. The charcoal body 10 containing wax helps the stable combustion of charcoal because the wax is vaporized by high temperature during combustion and burns by combining with oxygen existing around it.

In the drying step S108 according to an embodiment, the charcoal body 10 may be taken out from the wax solution and dried at room temperature for 1 to 24 hours. According to one embodiment, in the drying step (S108), by drying the charcoal body 10 at a certain angle so as to be perpendicular or inclined to the ground, the wax solution embedded in the charcoal body 10 can be adjusted to flow downward. have.

Hereinafter, the present invention will be described in more detail through specific examples. The following examples are only one example for aiding understanding of the present invention, so the scope of the present invention is not limited or limited thereto.
