ブロツク装入するためには不十分である。 Traditionally, the method of charging coking coal in Japan has been widely adopted as top-charging, in which bulk material is dropped into each kiln through a charging car through a charging hole at the top. Recently, a method of partially charging briquette coal has been developed in which the bulk density of the top-charged coking coal is increased to improve coke strength. This conventional method is
This method increases the bulk density by approximately 10% by forming coking coal into briquettes using a double roll forming machine and mixing in an amount of charged coal equivalent to approximately 30% of the briquettes. However, even though this method increases the bulk density, the value is at most about 0.78 dry tons/ m3 ,
Bulk density 1.0 wet tons/m 3 as required by the present invention
(0.91 dry tons/m 3 at a moisture content of 9%) This is not sufficient for charging into blocks, as it must be considerably lower than those above.

Moreover, the stroke of the hydraulic cylinder becomes longer, and the pressurizing area is large, and the mold as a whole is required to be strong enough to withstand the pressure, resulting in an oversized molding device, which in turn leads to an increase in costs. . others,
This conventional apparatus requires a dedicated process for taking out the compressed charcoal from the mold, which has the disadvantage that the molding process takes a long time.

に好適な方法である。以下にその構成の詳細を説
明する。 The present invention allows compressed molten coal to be charged into blocks while leaving a part of the compressed molten coal that has already finished compression molding at the outlet of the mold, and at the same time, fills the remaining space inside the mold. Newly charged coking coal and compression molded subsequent compression molded coal are tracked and combined with the tail end of the previously molded already compressed molded coal to obtain a bulk density of 1.0.
This is a method of obtaining compression briquettes by repeatedly extruding briquettes of wet ton/m 3 or more in sequence. By using a partition plate when the desired length is reached, the compressed molten coal is separated only at the point where the partition plate is inserted and does not coalesce; in other words, it can be made into any size. The preferred method is to produce it continuously by intermittently extruding it as compacted coal (matched to the size of the kiln for charging the blocks). The details of the configuration will be explained below.
本発明の着想の基本は、成型に際して、粉粒状

ある。 The basic concept of the present invention is that during molding, a partition plate is inserted into powdered coking coal, and the bulk density is 1.0 wet tons/
When compression molded to a size of m3 or more, the coking coal particles rearrange neatly along the end face of the compression molded coal with the partition plate inserted, so even if both end faces are brought into contact with each other under pressure, they do not coalesce. The point lies in the use of.

型の壁面に摩擦力が発生する。これはすでに成型
を終えた金型内にある既圧縮成型炭を押出す際も
同じであり、押出しに当つてはそれ自身がもつ摩
擦抵抗を超える圧力を加えなければならない。 Normally, when powdered raw coal in a mold is pressurized, frictional force is generated on the wall of the mold. This is the same when extruding compressed briquettes from a mold that has already been molded, and when extruding, it is necessary to apply pressure that exceeds the frictional resistance of the charcoal itself.

る。 Therefore, if some of the compacted coal formed in the mold is left in the mold, for example, by appropriately selecting the size (layer thickness) of the compacted coal to be left, it is possible to charge the already compacted coal. A frictional force is generated between the raw material newly added to the side and the tail end surface of the compressed molded coal remaining in the mold to withstand the pressure applied when the next compression molded coal to be tracked and combined is subsequently molded. Therefore,
If coking coal is newly charged into the mold space created between the press plate and the tail end surface of the compressed coal that has been previously formed, the press plate is pushed forward from one side of the charging side and compression molded. , Even if there is no fixed wall at the other end on the pressing direction side, the tail end face of the already compressed and molded coal acts as a fixed wall instead, so it is possible to mold the trailing compression molded coal that is subsequently molded. Furthermore, it is possible to manufacture products with a bulk density of 1.10 wet tons/m 3 or more.
Then, by applying even greater pressure, the compressed briquette remaining in the mold after being previously molded can be extruded out of the mold. In short, by repeating such operations, compression molded coal of any size can be continuously produced.
さらに、本発明では先行成型した既圧縮成型炭

型炭とが接合しても合体することはない。 Furthermore, in the present invention, when the compression molded coal of the subsequent molding that is tracked and combined with the previously molded compressed molded coal reaches a desired length, a partition plate is inserted, and then it is inserted into the mold in the same manner as described above. If coking coal is charged and the newly charged coking coal is pressurized by pushing the push plate in the same way, the coking coal particles will be rearranged neatly along the surface of the partition plate, so even if the partition plate is subsequently removed. Even though
Even if the previously formed compressed briquette coal is joined with the subsequent compression briquette coal, they will not coalesce.
従つて、所望の大きさの成型炭をそれらを連ね
たまま順次金型外へ連続的に押し出していくこと
ができるようになる。 Therefore, it becomes possible to continuously extrude briquettes of a desired size out of the mold one after another while keeping them in a row.

密度を1.20湿トン／m3以上にすることができる。 In addition, methods for increasing the bulk density when compressing coking coal by inserting partition plates to divide the size of briquette coal into desired sizes include increasing the pressing force, and increasing the charging amount of coking coal. There are methods to reduce the layer thickness by reducing the amount, or a combination thereof, and by using these methods, it is possible to achieve a high density of 1.20 wet tons/m 3 or more, if necessary.

ラスチツク板、石板等を用いることができるが、
その材質やまた厚さには制約はない。 As mentioned above, the partition plate that essentially determines the size of the compression molded coal can be used as a reaction force receiving plate when pressurizing raw coal and removed after pressurization. The partition plate may be left as it is between the compressed coal and the subsequent compression molded coal that is to be followed by the preceding molded coal. The latter method includes a method of setting the partition plate using a push plate, or a method of setting the partition plate from above or from the side of the mold. As for the material, iron plates, wooden plates, paper plates, plastic plates, stone plates, etc. can be used.
There are no restrictions on the material or thickness.

着火が行われて操業上のトラブルを発生する。 In the block charging method in which the compacted coal of a predetermined size obtained as described above is charged from the door side of the chamber furnace, the bulk density of the compacted coal is at least 1.0.
If there is no wet ton/ m3 , it may break during charging and cannot be smoothly charged into the furnace. If this is not achieved, in the worst case, the door will not be able to be installed and will collapse, or the compressed coal will continue to ignite, causing operational trouble.
このため、圧縮成型炭の嵩密度は1.0湿トン／

しなければならない。 Therefore, the bulk density of compression molded coal is 1.0 wet tons/
m 3 or more, preferably 1.15 wet tons/m 3 or more is required. From this, in the present invention, the pressure for compressing the charging raw coal by pushing the push plate is set such that the raw coal compressed by the pressurization is 1.0 wet tons/m 3
The size is necessary to form briquette coal with a bulk density of . In addition, for this purpose, the size of the compressed briquette coal that is partially left in the mold must be such that it can provide a frictional resistance that can withstand the above-mentioned pressing force.

周長Ｕの関数として理解される。 In other words, when granular coking coal is pressurized at a pressure Pt/cm 2 , a pressure P S t/cm 2 is generated on the wall of the mold, which increases the frictional force μP S t/cm 2 (μ: coefficient of friction). arise. Figure 1 shows the relationship between pressure P and frictional force μP S at a minute layer thickness dH. Since the weight of coking coal is small compared to its pressure, if it is ignored, the frictional force μP S is expressed as follows from equation (1): pressure P, layer thickness H of coking coal, pressurized area F, and circumference U of the mold.

る。 μP S =f(P, H, F, U) (1) Once the target furnace for charging the block is determined, the circumferential length U and pressurizing area F of the mold are determined from the furnace dimensions. The compressed coal at the layer thickness H has a frictional force μPS generated in response to the upward pressure, and in short, this frictional force μPS determines the supporting force of the residual compacted coal within the mold. Ru. Therefore, as mentioned above, the pressure P
and the layer thickness H, until the frictional force μP S is determined, the amount, that is, the size, of the pre-produced compacted coal that should remain can be determined by equation (1). According to experience, the pressure of the press plate required to obtain compacted coal with a bulk density of 1.0 wet tons/m 2 in a mold of 350 mm x 1000 mm is about 50 Kg/cm 2 . Then, the pre-compressed pre-molded coal having a bulk density of 1.0 wet tons/m 3 or more is left at the outlet inside the mold, and the raw coal is newly added to the press plate in the mold and the pre-compressed pre-compressed pre-molded coal. When charging and pressurizing the raw coal between the mold and the mold, the previously compressed briquette coal remaining in the mold functions as a supporting force when compressing the newly charged coking coal. However, the newly charged coking coal is compressed to the maximum due to the frictional resistance immediately before and after extrusion. In this way, by appropriately selecting the layer thickness of the compressed briquette coal produced in advance and the amount of the newly charged coking coal, that is, the layer thickness, the compression briquette coal with a bulk density of 1.0 wet tons/m 3 can be obtained. Pressure required to mold (50Kg/cm 2 ), preferably bulk density
The pressure (100 Kg/cm 2 ) required to obtain 1.15 wet tons/m 3 of compacted coal can be applied to the press plate.

By continuing to pressurize, the compressed molten coal produced in the mold can be extruded from the mold, and by performing these sequential operations, an endless amount of compressed molten charcoal can be produced. By configuring as described above, the mold only needs to correspond to the minimum size of the charging block, so it can be made economical and easy to handle, especially in the case of the preferred example shown. In the case where the pressurizing direction is horizontal, the pressurizing area is minimized, so the molding device can be made most compact and exhibits excellent economic efficiency. The pressing direction may be any direction, including vertical, horizontal, and diagonal directions.

Furthermore, the physical strength of the part to be compressed by inserting the partition plate, that is, the tip of the compacted coal, can be greatly improved.

圧縮成型炭となる。 FIG. 2 shown in the drawings shows one example of a typical manufacturing method of the present invention using a horizontal device. In step A, the previously produced compressed briquette coal is left on the exit side of the mold.
This shows the stage where coking coal is charged into the space behind it. The figure shown in (B) shows the stage in which the charged coking coal is compressed by the advancement of the push plate, and new compressed briquette coal (tracking briquette coal) produced by the next pressurization is tracked and combined with the previously generated compressed briquette coal. It is. Furthermore, the diagram shown in C shows a stage in which a pressure exceeding the frictional resistance of the compressed molten coal and the tracked molten coal is applied to push the press plate forward to force the compressed molten coal out of the mold. By the operation at this stage, the compressed briquette coal is pushed out of the mold, and the newly generated tracking briquette coal moves to the exit side of the mold.
By repeating these steps, it is possible to produce compression-molded charcoal that can be endlessly shaped into any size, and in particular, the compression-molded charcoal has a length that is suitable for the chamber furnace to be placed in the kiln.

大幅に向上させることができる。 As explained above, according to the present invention, compression briquettes of any length can be automatically produced, so even though continuous production equipment is used, there is no need for a briquette cutting process. be. In this sense, the present invention exhibits a remarkable effect when compressed coal is separated and charged into an indoor furnace. In addition, it is desirable that the outer shell of compression-molded coal has high physical strength to withstand collapse, etc., but since partition plates are used, the strength of the surface to be compressed becomes particularly large, and this increases as the pressing force increases. For example, bulk density 1.20 wet tons/m 3
The above can be achieved, and the physical strength of compression-molded coal can be significantly improved.
