Abstract

PURPOSE:To prevent scattering of dust in the air in the charging of red hot coke and prolongation of cycle time, by providing a device which turns a freely openable dust-preventive gate always upwards and in the closing direction. CONSTITUTION:When red hot coke 15 is charged into a coking tower 1 and a bucket gate 13 is turned in the closing direction, the dust-preventive gate 9 which is so devised as to move upwards always turns in the closing direction. As the bucket gate 13 is closed completely and a bucket 11 starts ascending, the dust-preventive gate 9 is closed under the action of counter-weight. Even after the bucket 11 has gone up further and is apart from a feeding hopper 5, the dust preventive gate 9 remains closed. Because of the sucking action of a dust collecting duct 7 within the feeding hopper 5, dust 16 formed as a result of charging of red hot coke is discharged through a dust collecting duct 7 and thus scattering of dust in the air from the top of the feeding hopper 5 is prevented.

Description

Detailed Description of the Invention The present invention is a coke dry extinguishing equipment (: red hot coke charging system) that prevents dust generated when red hot coke is charged into the cooling tower of the coke dry extinguishing equipment from scattering to the outside. It is related to the device.

The red hot coke charging device in the conventionally used coke dry fire extinguishing equipment is the
) is the cooling tower of the coke dry extinguishing equipment, and the upper part (2) is a water-sealed trough (BL) to which a charging hopper tC1 is attached. A packet gate is attached to the lower end of the gate so as to be openable and closable.

The packet carrying red-hot coke (red-hot coke sludge) (the south side stops just above the charging hopper (C). When the packet cage (e) is opened, the red-hot coke sludge) transported by TDL is bucket) (falls from the dl,
C2 is charged into the cooling tower (α) through the charging hopper (CI).

When the inside of the bucket) tdl decreases from ζ2, as shown in Figure 2, the packet gate (el is closed and the packet ldl immediately rises and moves to transport the next red hot coke Z. In this way, it cools down When the tower (with red hot coke in α1) is charged, dust (!11) is generated in the upper part of the cooling tower (aJ) and in the charging hopper tC+.

(bucket) (After the DL has moved from the top of the charging hopper (C), the top of the charging hopper (CI) will be open, so dust (GL) will be scattered into the atmosphere and deteriorate the environment. In order to prevent such environmental deterioration, the inside of the cooling tower (α) was removed from the bucket (dl) (two red-hot coke)?
Immediately after charging, it is effective to leave the packet (dl 'Y bucket in contact with the charging hopper tCI without raising the dl, and keep the dust (bucket) until the side has settled down with the packet gate te+ closed. However, this method has the disadvantage that the cycle time for charging red hot coke becomes longer.

The present invention was made for the purpose of charging red hot coke (5C2) so that dust does not scatter into the atmosphere and the cycle time does not become long. A dust collection duct is provided at the top of the charging hopper, and a dust prevention gate is installed at the upper end of the charging hopper (2. A dust prevention gate is installed to close the upper end of the charging hopper. The dust generation prevention gate is provided with a device 7 which is freely provided and acts on the dust generation prevention gate so that the gate always rotates upwardly and in the closing direction, and is opened when red hot coke is charged. This is a red hot coke charging device C2 in a coke dry fire extinguishing facility.

Next, one embodiment of the present invention will be described with reference to FIG. 3.

There is a water seal trough (2) at the top of the cooling tower (1) of the coke dry fire extinguishing equipment, and a bag hopper (5) consisting of an upper hopper (31) and a lower hopper (4) is connected to the water seal trough (2).
) and the upper part of the cooling tower (11).The upper hopper (31) is fixed in a fixed position, but the lower hopper (4) can be moved as shown in Figure 4. Hearth lid (6) (can be replaced twice).

The upper hopper (3) C2 is connected to the dust collection duct (7), and the upper end of the upper hopper (3) has a shaft (
8), the dust prevention gate (9) is rotatably mounted. A counterway (Ql) is attached to the outside of the dust prevention gate (9) opposite to the shaft (8)C, which normally biases the dust prevention gate (9) to rotate upward. . The dust generation prevention gate (9) comes into contact with a stopper (not shown) and stops in the horizontal position LL, and the upper end of the hopper (31 is held closed (2). As a means for holding the prevention gate (9) flat, a spring may be used instead of the counterway (Ql).

On the other hand, at the lower end of the packet αD for transporting red-hot coke, there is provided a packet gate OJ which opens and closes about the shaft α, and a guide roller 041 is attached to the lower surface of the packet gate OJ.

Until red hot coke is charged into the cooling tower (formerly 2), as shown in Fig. The inside of the cooling tower (1) is kept airtight and stands by in preparation for the next charge of red hot coke.

Immediately before charging the red hot coke (move the second lid (6),
Instead, the C2 lower hopper (4) is placed directly below the upper hopper (3). Next C: As shown in Figure 5, the charging hopper (
When descending toward the center of Q31, the ζ duct 0υ pushes down the dust prevention gate f9) via the guide roller 04. When the T-rot is fully open, the dust prevention gate (
9) is further pushed by the guide roller α, fully opened against the counterweight Onl, and reaches the state shown in Figure 6 (=2). (1) Inside (= charged.

After charging the red hot coke 09Z into the cooling tower (1), the 7th
As shown in the figure, when the packet gate (+31) is operated to look in the closing direction, the dust prevention gate (9), which is normally operated to move in the two directions, also rotates in the closing direction (=). Then, when the packet gate 03 is fully closed as shown in Figure 8 (2) and Kekerat D begins to rise, the second dust prevention gate (9) is closed by the force of the counterweight as shown in Figure 9. The dust prevention gate (
9) remains closed.

Since the inside of the charging hopper 451 is suctioned from the dust collection duct (71+2), the dust generated by charging the red-hot coke αS is discharged through the dust collection duct (7), and then transferred to the charging hopper (5). It is prevented from scattering from the upper end of the air into the atmosphere.

As shown in the third part, even after the C Nipa duct αυ rises and moves away, suction by the dust collection duct (7) continues, and the cooling tower +
11 and the inside of the charging hopper (5), the lower hopper (4) and the furnace lid (6) are replaced, and the condition shown in FIG. 4 waits until the next charging of red hot coke.

Note that the guide roller 041 attached to the lower surface of the packet gate 0'5 may be replaced with a sliding plate.

Since the present invention has the above-described configuration, the dust prevention gate can prevent dust scattering after charging red hot coke, and the dust prevention gate can be driven by a dedicated drive only by providing a small biasing means. The mechanism is simple because all you need to do is provide the mechanism.

Immediately after charging of the red hot coke is completed, the packets can be moved, which has the effect of shortening the cycle time.
