Description

[Detailed Description of the Invention] The present invention relates to a charging device for coke dry extinguishing equipment.

Conventionally, this type of charging device has a structure as shown in FIGS. 1 and 2.

As shown in Fig. 1, the charging port cover g is normally attached to the water sealing device e at the top of the cooling tower f, and when charging coke, the cover opening/closing mechanism j is operated by the power cylinder k. By pulling , due to the action with guide rail i,
After the charging port cover g is raised via the chain h,
Move laterally.

At this time, since the cart d also moves laterally, the hopper b mounted on the cart d also moves, and the hopper b stops right above the cooling if.

After that, when the coke packet a descends, the coke packet a lands on the hopper b, and the lower part of the hopper b is water-sealed by the deflection of the spring C. After that, as shown in FIG. The bottom of a is opened and coke is charged.

Note that 1 is the dust collection tact.

Therefore, the conventional charging apparatus shown in FIGS. 1 and 2 has the following drawbacks.

That is, first, the mechanism is complicated and therefore very expensive.

Second, dust smoke leaks to the outside when the charging port cover g and hopper b are moved.

Thirdly, the coke caught in the hopper b falls during the movement and enters the water sealing device e.

Fourth, since the hopper b moves on the spring C, it tends to sway.

The main purpose of the present invention is to simplify the charging device by making the charging hopper fixed, and to provide a charging device that eliminates the above-mentioned drawbacks of conventional devices.

For this reason, the configuration of the present invention includes a charging hopper fixed directly above the cooling tower, and a reciprocating body made of a spring that passes through the charging hopper and moves up and down as coke packets are attached and detached. The coke packet is attached to a coke packet. A bell-shaped loading port lid that opens and closes by moving downward and upward;
The cooling tower is characterized in that it includes a pipe provided above the metal touch part of the seal ring to suck in leak gas from the cooling tower immediately after leakage.

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 3 to 5.

In FIGS. 3 and 4, reference numeral 1 denotes a coke basket, which is suspended by a hoisting machine (not shown) via a hoisting hook 4, and red-hot coke 2 at about 1000° C. is charged inside. , and is covered with a cover 3, and a bottom plate 5 is attached to the bottom so that it can be opened and closed.

A charging hopper 6 is fixed directly above the cooling tower 7, and a landing table 8 for the packet 1 is provided passing through the hopper 6. This landing table 8 is supported by a spring 9 as a reciprocating body.
It is supported so that it can move up and down.

Reference numeral 10 denotes a bell-shaped charging port lid, which is suspended from the center of the landing table 8 and is designed to seal with a metal touch to the inner circumferential surface of a seal ring 11 provided at the top charging port of the cooling tower 7. ing.

That is, as shown in an enlarged view in FIG. 5, there is a water-cooled seal ring 11 at the top of the cooling tower 7, and the cooling tower is normally connected to the charging port cover 10 for sealing the charging port. This prevents the gas inside 7 from leaking.

In addition, 12 shown in FIGS. 3 and 4 is a fireproof material provided on the lower surface of the charging port lid 10, 13 is a dust collection duct, and 14 shown in FIG. 5 is a metal touch part of the seal ring 11. 15 is a water trough, and 16 shown in FIGS. 3 and 4 is a buffer,
17 is a seal plate for closing the beam through hole of the hopper 6.

In the charging device of the coke dry extinguishing equipment constructed as shown in FIGS. 3 to 5, red-hot coke is first received into the coke basket 1 from a coke oven (not shown), and then The coke basket 1 is transported by a hoisting machine to a position directly above a cooling tower 7 where coke is cooled.

When the coke basket 1 is placed on the landing table 8, the weight of the coke 2 and the packet 1 causes the spring 9 to spring up.
It starts to sag.

Further, when the coke basket 1 is lowered, the charging port cover 10 suspended below the landing table 8 is pushed down as the landing table 8 is lowered, and an opening is created in the upper part of the cooling tower 7.

Furthermore, the hoisting hook 4 is lowered by lowering the hoist, the bottom plate 5 is opened, and the coke 2 is charged into the cooling tower 7 through the charging hopper 6, as shown in FIG.

Note that the beam of the landing table 8 passes through the hopper 6, and in order for the landing table 8 to move up and down with the spring 9, a vertically long opening is required in the hopper 6. At this time, a seal plate 17 attached to the landing table 8 closes the opening of the hopper 6 to prevent coke from leaking out of the hopper 6 and dust from leaking.

When the charging of the coke 2 into the cooling tower 7 is completed in this way, the coke basket 1 is hoisted up by the hoisting machine, and the hopper 6 is also lifted upward by the force of the spring 9, and at the same time, the charging port cover 10 is also lifted up. It comes into contact with the seal ring 11 and stops.

Before this stop, the shock is softened by the buffer 16.

Further, during coke charging, dust in the charging hopper 6 is collected by the dust collecting duct 13.

On the other hand, normally, the gas inside the cooling tower 7 is sealed by the metal touch between the charging port cover 10 and the seal ring 11, but the gas leaking from that gap contains harmful components such as carbon monoxide, so the equipment Air is taken in through the intake pipe 14 to prevent leakage to the outside.

However, since the gas pressure at the top of the cooling tower is controlled to atmospheric pressure, there are almost no leaks.

As is clear from the above explanation, according to the present invention, firstly, the charging hopper is fixed and the charging port cover is not moved laterally, so the device is significantly simplified and is very advantageous in terms of cost. At the same time, the possibility of failure is reduced.

Moreover, with conventional equipment, the charging port cover must be removed before the charging hopper is placed at the coke charging position, which means that the inside of the cooling tower is exposed to the atmosphere, which reduces carbon monoxide by approximately 20%. In the present invention, the charging hopper is fixed and the charging port opens with the coke basket placed on top of the hopper, so the cooling tower It is not exposed to the atmosphere and is extremely advantageous in terms of pollution prevention.

In addition, with conventional equipment, coke powder adhering to the charging hopper fell during movement and entered around the charging port and into the water seal trough, contaminating the environment significantly, but with this invention, this has been significantly reduced. Ru.

In addition, conventional devices require a drive source to move the cart, which consumes a large amount of energy, and requires a spring to support a large stroke and large load, and when the spring is stretched, the shock is large. The charging hopper swayed and became unstable while the cart was moving, but with this invention,
Since there is no need for a trolley, it saves energy and
The unstable factors mentioned above are also eliminated.

Moreover, in the present invention, the landing table, which passes through the charging hopper fixed directly above the cooling tower, is provided via a reciprocating body made of a spring so that it can move up and down as coke packets are attached and detached. Since the bell-shaped charging port lid is suspended from the landing table, the bell-shaped charging port lid can be opened and closed without the need for a special drive device to allow the coke packets to descend. If the packet's own weight compresses the spring, the loading port lid will lower and open together with the landing table, and conversely, if the packet rises,
Since the loading port cover is closed by the restoring force of the spring, the device is simple and its opening/closing action is performed reliably.

Also, there is almost no leak gas from the cooling tower, but if
Even if there is leak gas, in order to prevent it from escaping into the outside air, an intake pipe is provided to suck it in immediately after the leak occurs, which is extremely advantageous in terms of pollution prevention.
