JPH0959643A - Method for discharging hardly pushable coke from coke oven - Google Patents

Abstract

PROBLEM TO BE SOLVED: To obtain a method for discharging hardly pushable coke whereby works done by human hands are decreased, i.e., saving is achieved. SOLUTION: This method comprises discharging hardly pushable coke from a coke oven when a pushing problem occurs during coke pushing-out work by attaching an open-fronted acceptor to the front side of the lower end of the head of a pushing-out ram, advancing the ram into a carbonization chamber, causing the ram to accept the hardly pushable coke, retreating the ram, and discharging the coke to the pushing machine side of the oven. An open-fronted and open-bottomed acceptor 3 is used as the acceptor, which is attached to the front side of the lower end of the head 2 of a pushing-out ram 1 and close to the bottom 8 of a carbonization chamber 4. A fallen coke bucket 6 is installed in the lower part at the pushing machine side in the carbonization chamber 4. Coke accepted by the acceptor 3 is allowed to fall by gravity through the bottom of the acceptor 3 into the bucket 6.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for discharging clogged coke in a coke oven. More specifically, the present invention relates to a method for extruding coke in a coke oven. The present invention relates to a labor-saving discharge method for discharging to the extruder side.

[0002]

2. Description of the Related Art In the operation of a coke oven, coke is extruded by an extruder after the completion of carbonization.
Specifically, the extrusion ram mounted on the extruder is advanced and charged into the carbonization chamber, and coke is extruded by the head of the extrusion ram. The extruded red-hot coke is accommodated in a fire train through a guide car, transported to a fire tower, and cooled by watering.

In the coke extrusion operation, sometimes jamming occurs, in which case a front open type receiver is mounted in front of the lower end of the head of the extrusion ram, and the extrusion ram is moved forward. After loading the coke in the carbonization chamber and receiving the tightly packed coke in the receiver, the extrusion ram is retracted,
The clogged coke is discharged to the extruder side of the coke oven.
Then, the coke received by the receiver is manually transferred to a debris bucket arranged in the lower part of the coking chamber on the extruder side of the coke oven.

[0004]

However, the forward and backward movement of the extrusion ram for discharging the coke due to the clogging of the coke oven on the extruder side is carried out not only once but also many times. Transferring the coke to the debris bucket requires a long period of manpower. The present invention
In view of such circumstances, an object of the present invention is to provide a method of discharging compacted coke, which requires less manual work and saves labor.

[0005]

That is, the gist of the present invention is to mount a front open receiver in front of a lower end of a head portion of an extrusion ram when clogging occurs in a coke extrusion operation in a coke oven. A method in which the extrusion ram is advanced and charged into the carbonization chamber, and after receiving the compacted coke in the receiver, the extruding ram is retracted and the compacted coke is discharged to the extruder side of the coke oven, As a receiver, a front and bottom open type receiver having a frame part on the front side and an opening capable of discharging received coke is used, and the receiver is brought close to the bottom of the carbonization chamber. Mounted in front of the lower end of the head of the extrusion ram, a debris bucket was placed in the lower part of the carbonization chamber on the extruder side of the coke oven, and the coke received by the front and bottom open type receivers by retreating the extrusion ram The bottom of the receiver Resides in the method for discharging 押詰 Mari coke in the coke oven, characterized in that to free-fall to Luo 落骸 bucket.

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is an explanatory view of a partially cutaway showing an embodiment of the method of the present invention, and FIG. 2 is an explanatory view showing an example of a front and bottom open type receiver used in the method of the present invention.

[0007] The present invention is applied to a coke pushing operation in a coke oven when clogging occurs. Basically, a front open receiver is mounted in front of the lower end of the head portion (2) of the extrusion ram (1), and the extrusion ram (1) is advanced to be charged into the carbonization chamber (4). After receiving the compacted coke (5) in the receiver, the extrusion ram (1) is retracted, and the compacted coke (5) is discharged to the extruder side of the coke oven.

The most important feature of the present invention is to use a front and bottom open type receiver (3) as shown in FIG. 2 and bring the extruder ram (1) close to the carbonization chamber bottom (8). Of the carbonization chamber (4) at the lower part of the extruder side, and a falling bucket (6) is arranged. The coke received by the vessel (3) is dropped from the bottom of the vessel (6).
And let it fall under its own weight. Reference numeral (7) in the figure denotes a service home on the extruder side.

The front and bottom open type receiver (3) shown in FIG. 2 is of a front open type similarly to a known container, and further has a bottom with a frame on the front side and discharges the received coke. It has an opening to gain. That is, the side plates (31) and (31) each having a substantially right-angled triangular shape and the rectangular back plate (3)
2) and a frame-shaped bottom plate (33).
The rear plate (32) is provided with a bolt hole (34) for attachment to the head (2).

The coke received by the front and bottom open type receiver (3) is supplied to a frame (33) on the front side of the bottom plate (33).
a), is dragged over the carbonization chamber bottom (8) acting as a temporary bottom of the front and bottom open-type receiver (3) and discharged to the lower extruder side of the carbonization chamber (4). It is dropped by its own weight from the bottom of the open bottom receiver (3) to the falling bucket (6). In addition, the coke discharged to the falling bucket (6) is further moved to, for example, an appropriate facility mounted on an extruder to be processed.

If the thickness of the frame portion (33a) on the front side of the bottom plate (33) is too small, the effect of catching coke is reduced and the efficiency of discharging coke is reduced. Therefore, the thickness of the frame portion (33a) usually needs to be 5 mm or more, and the upper limit is about 20 mm. The width of the frame portion (33a) is not particularly limited, but is usually 5 m.
m or more is sufficient, and the lower limit is about 20 mm. The bottom plate (33) needs a frame (33a) for catching coke on the front side thereof.
The overall shape does not need to be frame-shaped.

[0012]

According to the present invention described above, the work of transferring the coke received by the receiver to the debris bucket can be automated, so that manual work is reduced and labor is saved. A method for discharging compacted coke is provided.
