Description

[0001] Falling object processing apparatus [

More particularly, the present invention relates to a fall processing apparatus capable of rapidly processing fall objects occurring when a raw material is charged or discharged into a container for processing a raw material.

Generally, the coke used as a means of ensuring ventilation in addition to the role of a heat source, a reducing agent, and the like in a blast furnace is produced by carbonizing coal in a coke oven.

An extruder is installed in the upper part of the coke oven to allow coal to be introduced into the coke oven, and an extruder for discharging the gelled coke to the outside of the coke oven is installed at one side of the coke oven. An extruder A transfer car for storing and transporting the extruded glow-in coke is disposed, and a fire extinguisher is disposed under the transfer car.

After the drying of the coke oven is completed, the door of the coke oven is opened, the ram of the extruder is moved to the inside of the coke oven, and the glow coke stored in the coke oven is discharged to the transfer car side and loaded on the fire extinguisher. Then, the digested car loaded with the glowing coke moves to the digestion tower, and the gypsum coke is digested by the digested water sprayed from the digestion tower.

However, in the process of opening the coke oven door to extrude the coke oven inside the coke oven, some of the coke oven door has fallen to the floor and some of the coke oven has fallen to the floor during the process of extruding the coke oven by using an extruder There is a problem that coke is generated. Accordingly, the lower part of the coke oven in which the reduced coke is produced is provided with a low-grade coke processing device for processing the reduced coke. A coke oven treatment apparatus includes a coke pan in which coke oven is accommodated, and a coke hopper discharging the coke oven contained in the coke oven to a container or vehicle for collecting coke. The coke pan may be configured to be rotatable to the coke hopper side to discharge the coke oven by the coke hopper, or may be provided with an opening and closing door to discharge the coke oven to the coke hopper. In addition, the coke pan may be provided with a nozzle for spraying fire water for fire-fighting the petroleum coke, that is, the hot coke.

However, when a lot of coke ovens are generated, it is impossible to rotate the coke pan or open / close the door to discharge the coke oven to the coke hopper, so that the coke oven can not be discharged to the coke hopper at an appropriate time, And the like. In addition, when water is sprayed to extinguish the petroleum coke, a large amount of dust is generated. When the petroleum coke is used for a long period of time, these dusts accumulate in the coke pan to reduce the space for accommodating the coke, , And the operator must manually process the drop coke.

A controller (not shown) controls the operation of the moving means 420 and the driving means 430 according to a predetermined pattern, and controls the opening and closing of the injection nozzle 416.

Hereinafter, a method of treating fallow cokes using the apparatus 400 for treating a falling object according to an embodiment of the present invention will be described.

First, when the coal is completely dried in the coke oven 100, the operation of the moving means 420 is controlled before the extruded coke is produced as shown in FIG. 4 to advance the main body 410 to the coke oven 100 in the lower part of the coke oven 100. At this time, the outlet 414 formed in the section B of the main body 410 and the upper opening of the hopper 460 are communicated with each other.

Thereafter, the coke oven 100 of the coke oven 100 is opened to extrude the coke oven 100 produced in the coke oven 100 and the ram of the extruder 300 is introduced into the coke oven 100 through the coke oven 100, And enters the inside. At this time, the red coke attached to the coke oven 100 may drop to the main body 410 in the course of opening the coke oven 100. 5, the spray nozzle 416 is opened to spray the extinguishing water into the main body 410, for example, the section A of the main body 410. [ In addition, while the driving means 430 is operated to move the scraper 450, the dropped coke collected in the section A is moved to the section B and discharged to the hopper 460 through the discharge port 414. At least the injection of hydration water may be performed for about two minutes after the hook of the coke oven 100 extractor is brought into close contact with the coke oven 100 to open the coke oven 100. At this time, the operation of the driving means 430 may be performed in the same manner as the injection of the extinguishing water or after the injection of the extinguishing water is stopped. The dropping coke collected in the main body 410 is discharged to the hopper 460 while being extinguished in real time, thereby preventing or preventing the main body 410 or the hopper 460 from being damaged by the high temperature drop coke. In addition, since the processing of the instant powdery coke is performed quickly, it is also possible to suppress the occurrence of dusts or the like generated in the process of digesting the instant powdery cakes to the body 410, thereby causing a malfunction.

After the coke oven 100 of the coke oven 100 is opened, the ram of the extruder 300 enters the coke oven 100 to extrude the coke oven 100 and then retracts the ram to the outside of the coke oven 100 do. At this time, the extruded coke oven (100) can be discharged through the coke oven (100) while the ram is extruded out of the coke oven (100). The driving means 430 is operated with the spraying of the extinguishing water as described above for about two minutes after the extrusion of the glowing coke is completed and the ram is taken out of the coke oven 100 and discharged from the coke oven 100 The petroleum cokes can be extinguished and discharged to the hopper 460 through the discharge port 414.

Thereafter, when extrusion of the glow-in-coke is completed and the ram is completely drawn out, the moving means 420 is operated to retract the main body 410 from the coke oven 100 as shown in FIG.

Although the present invention has been described in connection with certain exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. Therefore, the scope of the present invention should not be limited by the described embodiments, but should be defined by the appended claims and equivalents thereof.
