Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a return coke processing device attached to a coke extruder of a coke oven, and particularly relates to a return coke processing device for processing return coke by reinjecting it into the oven without requiring manual labor. This invention relates to a return coke processing device for a coke extruder that can perform the following steps.

In conventional coke ovens, the returned coke that spills out of the oven when removing the oven lid, extruding coke with a coke extruder, cleaning the oven lid frame, etc. is either manually fed into the oven or put into the hopper on the coke extruder. In the past, the waste was manually put into the water and discharged to the ground for disposal. However, coke extruders have a very high temperature, creating a poor working environment, and are dangerous and reedy, resulting in poor working conditions.

Another method for processing returned coke is to install a moving chute, a chain conveyor, and a hopper on the coke extruder, and automatically transport each returned coke in the order of moving chute → chain conveyor → hopper, and then transfer it to an above-ground storage tank. After being stored, it was transported by truck, etc. However, with this method, the returned coke that had been collected in the hotpot had to be treated separately from the coke in the furnace, which was cumbersome.

This invention was made in order to solve the above-mentioned drawbacks in the return coke treatment of the conventional coke oven, and by mechanically reinjecting the return coke into the furnace, it is possible to eliminate the need to obtain it. It is an object of the present invention to provide a coke extrusion type return coke processing device that can improve work efficiency.

The present invention will be explained below based on embodiments shown in the drawings.

In FIGS. 1 to 4, on the base 2 of the coke extruder that is moved on the platform 1, a pair of front swing levers 3, 4 and a pair of rear swing levers 5, 6 have lower ends. The front swing levers 3 and 4 and the rear swing levers 5 and 6 are located at positions facing each other in a direction perpendicular to the coke extrusion direction (the direction of the arrow in Figures 1 and 2), and each swing lever 3, 4 is , 5.6 are mounted rotatably in a vertical plane parallel to the direction of coke extrusion.

The tips of the front swing levers 3 and 4 and the rear swing levers 5 and 6 are connected to the sides of the upper and lower mounts 7 disposed between the front swing levers 3 and 4 and the rear swing levers 5 and 6. Each is rotatably attached to the One end of a swinging field 8 is fixed to the lower end of the rear swinging levers 5 and 6 coaxially with the respective rotation shafts, and a rear end of the swinging field 8 is fixed to the other end of the swinging field 8. A bogie vertical cylinder 90 rod mounted on the platform 2 is pivoted, and the operation of the bogie vertical cylinder 9 rotates the rear swing lever 5.degree.6. The vertical frame 7 is positioned horizontally on the machine base 2 when each swing lever 3, 4, 5, 6 is tilted backward with respect to the machine base 2, and each swing lever 3, 4, 5, 6 When triggered,
The trap is lifted in a horizontal position and moved forward in the coke extrusion direction.

As can be seen from FIG. 6, both side frames 10 of the upper and lower frames 7 have an I-shaped cross section, and a rail 11 is fixed to the lower surface of the upper flange inside each side frame 10. The tip of the rail 11 is located further back than the tip of the side frame 10.

And between the both side frames 10 of this upper and lower frame 7, there is a forward and backward moving carriage 1.
A pair of front rollers 13 and a pair of rear rollers 14, which are rotatably attached to both sides of this forward and backward moving truck 12 by horizontal shafts perpendicular to the coke extrusion direction, are connected to the inner lower flange of the side frame 10, respectively. It is located between the rails 11, so that the reciprocating cart 12 is movable in the longitudinal direction along the side frame 10 with respect to the upper and lower frames 7. The tip of the rod of a cylinder 15 for forward and backward movement, which is attached to the bottom of the vertical frame 7 in parallel to the coke extrusion direction, is pivoted to the bottom of the back and forth carriage 12. By the operation of , the forward/backward movable trolley 12 is moved back and forth with respect to the upper/lower frame 7 .

5- A gate 16 is pivotally supported at its rear end by a shaft 17 at the front end of the forward/backward moving truck 12 in a vertical plane outside parallel to the coke extrusion direction. One end of a swinging field 18 is fixed to the rear end of the gate 16 coaxially with the shaft 17, and the other end of this swinging field 18 has a forward and backward moving bogie 12 fixed thereto.
The tip of a rod of a gate opening/closing cylinder 19 fixed parallel to the coke extrusion direction is pivoted to the shaft, and the gate 16 is opened/closed by the operation of the gate opening/closing cylinder 19.

When the gate opening/closing cylinder 19 is inactive, the gate 16 is brought into contact with the lower end of both side plates 20 at the front end of the forward/backward moving truck 12, and forms a packet together with the side plates 20.

Furthermore, a pair of flaps 21.22 are respectively supported by flap opening/closing shafts 23.24 at the upper ends of the side plates 20 at the front end of the forward/backward moving truck 12. As shown in FIG. The lid opens horizontally to the outside,
The cover can be rotated inward to freely swing between the upright closed position and the closed position.

The width of the gate 16 is slightly narrower than the width of the coke oven 25 so that it can be inserted into the coke oven 25, and when the flaps 21 and 22 are opened, the width between both ends of the gate 16 is slightly narrower than the width of the coke oven 25. The width of the coke oven 25 is wider than the width of the coke oven 25, and when the lid is closed, the coke oven 25 fits within the width of the gate 16, and can be inserted into the coke oven 25 together with the gate 16.

The flap opening/closing shafts 23 and 24 each extend parallel to the coke extrusion direction to the rear end of the forward and backward moving truck 12.
As can be seen from FIG. 3, one end of a swinging field 26 is coaxially fixed to the rear end of one flap opening/closing shaft 23. The other end of the swinging field 26 is pivoted to the tip of a rod of a flap opening/closing cylinder 27 that is attached to the rear of the forward/backward moving truck 12 in a direction perpendicular to the coke extrusion direction. The flap 21 is opened and closed by the operation of 27. Furthermore, the flap opening/closing shaft 2
The mounting position of the swing field 26 of No. 3 is also in the front position, as shown in FIG. One end is coaxially fixed, and the other flap opening/closing shaft 24
A swing field 29 is coaxially fixed at one end at a position corresponding to the swing field 28 so as to extend vertically upward when the flap 22 is in an open state. And the swinging world 2B
and the tip of 29 are connected by a connecting rod 30.

A tar pan 32 that is inclined upward toward the oven frame 31 is disposed at a position below the oven frame 31 of the coke oven 25 and opposite the tip of the gate 16 .

Next, the operation of the returned coke processing device of the coke extruder will be explained. When the returned coke processing device is in an inactive state, the forward and backward moving carriage 12 is held in the backward position with respect to the upper and lower mounts 7, and the upper and lower mounts 7 are The rear swing levers 3 and 4 and the rear swing levers 5 and 6 are tilted backward and are in a standby position on the coke extruder base 2, as shown by solid lines in Figures 1 and 2. . At this time, the gate 16 is closed and the flaps 21.22 are also closed (shown in the open state in FIGS. 1 and 2 for ease of understanding).

When extruding coke in the coke oven 25 by the coke extruder, when the machine stand 2 is moved on the platform 1 and positioned at a predetermined coke extrusion position in front of the coke oven 25, the tip of the gate 16 is pushed out from the coke oven 25. The furnace frame 31 in the front part of the tar pan 3 is also located at a lower position.
2 is faced. After this, when the forward/reverse movement cylinder 15 is operated, the forward/reverse movement truck 12 is advanced from the upper/lower frame 7, and the tip of the gate 16 is brought into contact with the tar pan 32. Further, just before the tip of the gate 16 comes into contact with the tar pan 32, the front roller 13 comes off the rail 11 and is positioned in front of the tip of the rail 11. As the forward/backward carriage 12 is further advanced relative to the vertical frame 7, the tip of the gate 16 slides on the tar pan 329- and comes into contact with the lower end of the furnace frame 31 (the first
It is guided at the position shown by the chain line in the figure) t.

At this time, since the front roller 13 is off the rail 11, the forward/reverse carriage 12 is gradually tilted upward around the rear roller 14, allowing the tar pan 32 to guide the tip of the gate 16. It is something. In this way, attach the tip of the shim gate 16 to the furnace frame 32 using the tar pan 32.
By guiding the furnace frame 31 to the lower end of the
The gate 16 can be positioned at a predetermined position under the oven frame 31 regardless of errors in the mounting position of the coke oven or errors due to thermal deformation of the coke oven.

Next, the seven-lap opening/closing cylinder 27 is operated to retract the rod, and the flap opening/closing shaft 23 is rotated via the swing field 26 to open the flap 21. At the same time, the flap opening/closing shaft 24 is rotated in the opposite direction to the flap opening/closing shaft 24 via the swinging field 28, the connecting rod 3°, and the swinging field 29, and the flap ax 2 is opened. And keep this state10
- During operations such as removing the oven lid, extruding coke, and cleaning the oven lid frame, return coke that falls from inside the coke oven 25 is removed from the gate 16 and the flap 21.2.
Receive on 2.

After a series of coke extrusion operations are completed, the forward and backward movement cylinder 15 is operated in the opposite direction to move the gate 16 back from the furnace frame 32, and the flap opening/closing cylinder 27 is operated in the opposite direction to close the flap 21. 22 is closed.

Next, when the bogie up/down cylinder 9 is activated, the rear swing levers 5, 6 are pulled up, and the front swing levers 3, 4 are also pulled up. 11, which maintained a horizontal position, was lifted,
The front end of the reciprocating truck 12 is inserted into the coke oven 25. After this, the cylinder 15 for forward and backward movement is operated again to move the forward and backward movement truck 12 forward, and the gate 16 is opened to the coke oven 2.
Insert it all the way to 5. And gate opening/closing cylinder 19
By operating the gate 16 through the swing ring 1B, the returned coke on the gate 16 is transferred to the coke oven 25.
