Description

Red heat coke receiving device

The present invention relates to a red hot coke transfer device in a coke dry fire extinguishing equipment (sometimes referred to as CDQ equipment).

The red hot coke produced by carbonizing coal in the coke oven's carbonization chamber is pushed out of the coke oven's kiln and is carried on a truck that runs on a fire extinguisher rail provided along the coke oven. Received by the corpse. A carriage equipped with a transport bucket receiving red-hot coke moves to the hoisting tower, and the transport bucket is lifted by the hoisting tower. The lifted conveyance bucket moves above the coke cooling tower, and the red hot coke in the conveyance bucket is charged into the coke cooling tower. The red hot coke charged in the coke cooling tower is cooled by an inert gas, and the sensible heat is recovered as steam (see Patent Document 1).

The red hot coke pushed out from the coke oven is received by the transport bucket via the coke guide wheel. The coke guide wheel has a guide function for guiding the red hot coke extruded from the coke oven to the transport bucket, and a dust collecting function for collecting dust and gas generated when the red hot coke is received.
Since the coke guide car having such a function needs to move in front of the furnace in the coke oven, the coke guide car traveling rail is provided above the fire extinguisher rail and along the coke oven. .
Moreover, the dust collection hood having the dust collection function needs to be arranged so as to cover the transport bucket. Therefore, the cork guide vehicle traveling rail is provided on both sides of the fire extinguishing vehicle rail so as to straddle the fire extinguishing vehicle rail on which the transport bucket travels. Among the coke guide vehicle running rails, the rails provided on the coke oven side are called coke oven side rails, and those provided on the side opposite to the coke oven are called anti-coke oven side rails.

An outline of a method for transporting red hot coke in the above-described coke dry fire extinguishing equipment will be given.
The red hot coke pushed out from the coke oven is guided by the coke guide wheel and received in the transport bucket. When the red hot coke is received by the transfer bucket, the carriage equipped with the transfer bucket receiving the red hot coke moves to the hoisting tower, and the transfer bucket is lifted by the hoisting tower.

There are two methods for lifting the transport bucket with the hoisting tower, a direct take method and a traverser method.
The direct take-up method is a method in which a hoisting tower is installed in front of a coke oven or the like, and a conveyance bucket in front of the coke oven is directly lifted from a fire extinguisher rail provided along the coke oven in the vertical direction.
In addition, the traverser method is that the hoisting tower is installed at a location slightly away from the coke oven, and the cart loaded with the transport bucket is moved to the hoisting tower from the fire extinguisher rail provided along the coke oven. Furthermore, this is a method involving horizontal movement.
JP 2006-193567 A

The direct capture method and the traverser method have advantages and disadvantages, respectively.
<Advantages of direct capture method>
In the case of the direct take-up system, since the transfer bucket is directly lifted from the position of the fire extinguisher rail provided along the coke oven, the transfer cycle time of the transfer bucket can be shortened.
<Demerits of direct capture method>
It is necessary to lift it so as to avoid the anti-coke oven side rail provided to straddle the fire extinguisher rail on which the carriage carrying the transport bucket travels.
That is, the conveying bucket needs to be sized and shaped so as not to interfere with the anti-coke oven side rail when being lifted. For this reason, the shape of the conveyance bucket that increases the capacity and does not interfere has to be rectangular.
However, if the conveyance bucket is rectangular, the conveyance bucket itself cannot be swiveled after receiving the red hot coke, and therefore, the particle size distribution of the received red hot coke is not averaged and the particle size distribution is biased. It accumulates as it is. If the particle size distribution of reddish coke in the transport bucket becomes uneven in this way, it will be put into the coke cooling tower as it is, and the particle size distribution in the coke cooling tower will also become non-uniform, and cooling performance by inert gas It becomes a factor to inhibit.

<Advantages of the traverser method>
In the case of the traverser method, the transport bucket is temporarily moved from the position of the fire extinguisher rail provided along the coke oven, so there is a problem of interference with the anti-coke oven side rail when lifting the transport bucket. There is no. Therefore, the conveyance bucket can be a swivel type (round shape) that can prevent segregation, and the particle size distribution in the coke cooling tower can be made uniform.
<Disadvantages of traverser method>
However, in the case of the traverser method, the equipment cost is excessive and the cycle time becomes long.
Also in the case of the traverser method, when moving the transport bucket laterally, it is necessary to pass the transport bucket so that it passes under the anti-coke oven side rail, so the height of the anti-coke oven side rail is higher than the transport bucket. In some cases, the traverser method may not be adopted in the first place.

As described above, when the direct take method is adopted, the shape and size of the transport bucket are limited, and in the case of the traverser method, there is a problem that the cycle time becomes long. When planning to increase the size of CDQ facilities in recent years, it is an important issue to be worried about.

The present invention has been made to solve such problems, and has an object to obtain a red hot coke receiving and conveying apparatus that can efficiently transfer red hot coke without restrictions on the shape and size of the transfer bucket. .

The hoisting tower 11 is installed on one end side of the coke oven 3 so as to protrude toward the fire extinguisher rail 5 side.

Details of each component apparatus having the above-described arrangement relationship will be described below.
<Winding tower>
The hoisting tower 11 includes a hoisting frame 19 that is a basic structure of the hoisting tower 11, a guide rail 21 that is installed on the hoisting frame 19 and guides the transport bucket 9 when it is lifted, and a part of the guide rail 21. A guide rail drive device 23 that moves up and down and a hoist 51 that lifts the transport bucket 9 are provided.
The guide rails 21 are disposed on both sides of the transport bucket 9 and guide guide rollers (not shown) provided on the transport bucket 9. As shown in FIG. 1, the guide rail 21 is formed by a guide rail fixing portion 21a whose upper side serves as an outer frame, and the lower side is formed by a guide rail moving portion 21b. The guide rail fixing portion 21a has a guide rail moving portion. A so-called telescopic structure in which a part of 21b is inserted and the entire length can be expanded and contracted is formed. With such a telescopic structure, the guide rail movable portion 21b can be moved up and down. The guide rail movable portion 21b is provided with four leg portions 27 that support the hoisting frame 19 when lowered (see FIGS. 1 to 3).

The four leg portions 27 are on both sides of the guide rail movable portion 21b and are fixed to the guide rail movable portion 21b. The leg portion 27 is fixed to the guide rail movable portion 21b, so that the guide rail movable portion 21b can be lifted and lowered together. At the lower end of each leg 27, a divergent landing bracket 29 is provided for load distribution.
The four legs 27 land on the overhanging brackets of the coke oven side rail 15a and the anti-coke oven side rail 15b on the coke oven 3 side on which the coke guide wheel 13 travels when descending. The four leg portions 27 bear about 50% of the load of the hoisting frame 19 when the transport bucket 9 is lifted. For this reason, compared with the conventional example without the leg part 27, the strength of the hoisting frame 19 can be reduced, and its weight can be reduced.
Since the coke oven side rail 15a and the anti-coke oven side rail 15b have the strength that the coke guide wheel 13 travels, the leg portion 27 lands and supports the load of about 50% of the hoisting frame 19. However, there is no problem in strength.

In order for the leg 27 to bear the load of the hoisting frame 19, it is necessary to integrate the leg 27 and the hoisting frame 19 so that the load can be transmitted. Therefore, the hoisting frame 19 has an integration device 31 for integrating the leg 27 and the hoisting frame 19.
As shown in FIGS. 4 and 5, the integrated device 31 is installed so that channel-shaped brackets 33 are provided on both side surfaces of the leg portion 27 so as to project laterally and a predetermined gap is provided vertically. The connection block 35 is inserted into the gap between the channel brackets 33 from the hoisting frame 19 side. The connecting block 35 is inserted into a through hole 39 formed in a support base 37 fixed to the hoisting frame 19, so that the connecting block 35 can be inserted into and removed from the gap between the channel brackets 33.

The connection block 35 is provided with a loose taper so that the tip side is slightly tapered, and the gap between the channel-shaped brackets 33 is slightly reduced on the side where the tip side of the connection block 35 is arranged so as to correspond to this. Is set to In other words, the gap between the connection block 35 and the channel bracket 33 is connected by a cotter method, and therefore can be connected without rattling.
By inserting the connecting block 35 into the gap between the channel brackets 33, the load acting on the hoisting frame 19 is transmitted to the legs 27 via the connecting blocks 35 and the channel brackets 33. As a result, the load acting on the hoisting frame 19 can be supported by the legs 27.

The structure of the connection drive device 41 that drives the connection block 35 in order to insert and remove the connection block 35 into the gap between the channel brackets 33 is as follows.
The coupling drive device 41 includes an electric cylinder 43 installed on the hoisting frame 19 and an arm member having one end pin-coupled to the tip of the rod 43a of the electric cylinder 43 and the other end pin-coupled to the hoisting frame 19 side. 45 and a connecting plate 49 that is connected to a long hole 47 formed in the center of the arm member 45 so that one end is movable in the long hole 47 and the other end is fixed to the connecting block 35. Has been.

As shown in FIGS. 4 and 5, the coupling drive device 41 configured as described above extends the rod 43 a of the electric cylinder 43, so that the coupling block 35 moves to the leg portion 27 side, and the channel type bracket The leg portion 27 and the hoisting frame 19 are integrated into a state in which the load can be transmitted.
Further, by retracting the rod 43a of the electric cylinder 43, the connecting block 35 comes out of the gap of the channel bracket 33, and the integration is released. By releasing the integration, the guide rail movable portion 21b of the guide rail 21 to which the leg portion 27 is fixed can be raised.

As described above, the guide rail movable portion 21b of the guide rail 21 can be moved up and down, and the leg portion 27 lands in the lowered state as shown in FIG. On the other hand, as shown in FIG. 2, when the guide rail movable portion 21b is raised, a space in which the coke guide wheel 13 can travel is formed below.
Various modes can be considered for the timing of the raising / lowering operation of the guide rail movable portion 21b of the guide rail 21. For example, the guide rail movable portion 21b may be always in the raised position, and the guide rail movable portion 21b may be lowered when the transport bucket 9 is lifted so that the leg portion 27 and the hoisting frame 19 are integrated. Alternatively, the guide rail movable part 21b and the hoisting frame 19 are always integrated with the leg 27 and the hoisting frame 19 integrated with the guide rail moving part 21b in the lowered position. 19 may be released to raise the guide rail movable portion 21b.
