Description

[Detailed Description of the Invention] (Industrial field of application) This invention relates to a carbonization furnace for producing charcoal and the like, and the purpose thereof is to prevent loss due to thermal deformation of the dolly and use only the end plate of the dolly as an end plate. The purpose of the present invention is to provide a carbonization furnace that can be used as a lid for the opening part of the furnace and can be simplified in work.

(Prior Art and its Problems) Conventionally, there is a carbonization furnace for producing charcoal or the like as shown in FIG.

In this conventional carbonization furnace (a), an opening (c) is formed on the lateral side of the furnace (b), and a dolly (e) with raw materials placed in and out of the furnace (d) is taken in and out from this opening (c). The raw material is ignited, the truck (e) is housed in the furnace (d), and air is gradually fed into the furnace (d) to carbonize the raw material to obtain charcoal or the like.

However, in such a carbonization furnace (a), the truck (e) is
After being stored in (d), the opening (c) is closed by the refractory cover (f), so the truck (e) is exposed to the temperature in the furnace (d) that rises to near 800 ° C. However, it could not dissipate heat and was easily lost due to thermal deformation.

In addition, after accommodating the truck (e) in the furnace (d), the opening (c)
The work was troublesome because it was necessary to close the cover with the lid (f).

(Problems to be solved by the invention) In view of the above circumstances, it has been desired in the industry to create a carbonization furnace that can prevent loss due to thermal deformation of the dolly and can perform work easily.

(Means for Solving the Problem) In this invention, openings are formed on both lateral sides of the furnace, and in the carbonization furnace for loading and unloading minecarts with raw materials placed in the furnace through the openings, the minecarts are the bottom plates. End plates are respectively formed from both ends, and inner surfaces of the bottom plate and the both end plates are respectively covered with a refractory material layer, and the refractory material layers on the inner surface of the both end plates are respectively located in the both openings. The above problems are solved by providing a carbonization furnace in which both end plates are exposed outside the furnace.

(Example) The Example of this invention is described based on drawing.

1 (A) to 1 (C) are views for explaining a carbonization furnace according to an embodiment of the present invention, in which (1) shows the carbonization furnace.

First, the structure of the carbonization furnace (1) will be described.

Reference numeral (2) is a furnace, and openings (3) are formed on both lateral sides of the furnace.

The dolly (5) containing the raw materials is put into and taken out of the furnace (4) through the opening (3).

The dolly (5) is formed in a U shape by raising the end plates (7) from both ends of the bottom plate (6).

Both end plates (7) and (7) are detachable from the bottom plate (6).

The inner surface of each of the end plates (7) and (7) and the bottom plate (6) is covered with a refractory material layer (8).

The refractory material layer (8) is a lightweight refractory material (10) such as refractory cement surrounded by refractory bricks (9) arranged on the edges of the inner surfaces of both end plates (7) and (7) and the bottom plate (6). Has been formed.

The trolley (5) has an idle wheel (11) at the bottom, and runs on the rail (12) drawn into the furnace (4) through the opening (3) to move in and out of the furnace (4). To be done.

In the figure, (13) is a viewing window, the end plate (7) and the refractory layer (8)
Is formed to penetrate.

At the storage position in the furnace (4) of the truck (5), both refractory layers (8) and (8) on the inner surfaces of both end plates (7) and (7) are located in both openings (3) and (3), respectively. Both end plates (7) and (7) are exposed while being positioned.

In the figure, (14) is both side walls constituting the furnace (2), and (15) is both side walls.
A roof separated from (14), (16) a beam that suspends the roof (15), (17) a turnbuckle, (18) an air supply passage, (19) an exhaust passage, and Fig. 1 (D (20) in () is a spacer attachment.

The configuration of the carbonization furnace (1) according to one embodiment of the present invention is as described above, and the method of using the carbonization furnace will be described below.

First, when producing charcoal, put raw materials such as wood on the truck (5), ignite this raw material, and turn the truck (5).
Is housed in the furnace (4), and the gap between the refractory layer (8) of both end plates (7) and (7) of the truck (5) and both openings (3) and (3) of the furnace (2) ( 19) is sealed with clay, etc., the raw material is carbonized while sending air little by little from the air supply passage (17), and the truck (5) from the inside of the furnace (4) is timely.
To collect charcoal.

In the process of accommodating the truck (5) inside the furnace (4) and carbonizing the raw materials, the inside temperature of the furnace (4) reaches a high temperature near 800 ° C, but the heat is temporarily passed through the refractory layer (8). The heat transferred to the bottom plate (6) and both end plates (7) and (7) of (5), and the heat transferred to the bottom plate (6) is the end plate.
The heat is radiated to the outside of the furnace via (7), and the heat transmitted to the end plate (7) is radiated to the outside of the furnace from the end plate (7) itself.

The spacer attachment (20) in FIG. 1 (D) is for adjusting the height of the inner bottom surface of the truck (5) by stacking one or more plates on the truck (5) and lowering the inner bottom surface. In this case, since the raw materials can be stacked higher, the temperature difference between the upper and lower positions is large and the quality is somewhat uneven, but large-scale processing is possible. It becomes low and is disadvantageous for mass processing,
The temperature difference between the upper and lower positions is small and the quality is uniform.

(Effect of the device) This device has openings formed on both lateral sides of the furnace.
In a carbonization furnace for loading and unloading minecarts with raw materials placed in the furnace through this opening, the minecarts are formed by raising end plates from both ends of the bottom plate, and the inner surfaces of the bottom plate and both end plates are made of a refractory material layer, respectively. Since the refractory layers on the inner surfaces of the both end plates are covered with the refractory material and the both end plates are exposed outside the furnace, the following effects can be obtained.

That is, the heat inside the furnace is once transferred to the bottom plate and both end plates of the truck through the refractory layer, the heat transferred to the bottom plate is radiated to the outside of the furnace through the end plates, and the heat transferred to the end plates is Since heat is radiated from the plate itself to the outside of the furnace, loss due to thermal deformation of the truck is prevented.

Further, since the end plate of the truck is shared not only as the end plate but also as the lid of the opening of the furnace, it is not necessary to close the opening with a separate lid after housing the truck. The work is simplified.
