Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a compacted coal case operating station in a coke oven.

Traditionally, coal was loaded into a coke oven through a charging hole on the furnace.
A top charging method was used in which a coal loading car that could run over the furnace was used to charge the coal dropwise, but recently, in order to increase the bulk density of the charged coal, the coal is stamped and then charged into the furnace. Methods have been proposed to improve extrudability and productivity.

In this method, as shown in Fig. 1, a coal molding chamber d having a stamping device C is installed on a trolley capable of moving the rail a of the extruder yard to the coke oven, and a coal molding chamber d with a stamping device C is installed at the bottom of the molding chamber d. Coal is charged onto the receiving plate e that has been heated, and is stamped using a stamping device C into a shape and size suitable for the furnace chamber f of the coke oven A to make a coal cake g (compression molded coal). is moved to the front of the desired furnace chamber f, and the receiving plate e is moved to the front of the desired furnace chamber f.
The coal cake g is charged into the furnace chamber f using a charging device, and only the receiving plate e is pulled back to the forming chamber d, and the coal cake g is placed on the receiving plate e again.
This involves repeating the operations to form the .

Although this method is useful for improving coking properties and productivity, the stamping of coal, the charging of coal cake g into furnace chamber f, and the pulling back of receiving plate e must be carried out in a certain temporal order. However, at least the stamping operation cannot be started until the receiving plate e returns to the coal molding chamber dK, and there is a lot of room to improve the work efficiency during that time.

The compression-molded coal case operating station in the coke oven according to the invention is capable of using at least two cases for storing coal cake g, and is a compression-molded carbonation type device,
When carrying out an operation to transfer the case in which the coal cake has been stored to the coal cake charging cart, the coal cake contained in the cart has already been charged into the furnace chamber f, and the case is transferred to the compression molding carbonation mold device 1. When the car returns, the empty case is removed from the charging cart using a hoist and held in the upper space, and as soon as the compression molded coal storage case is sent out from the compression molding carbonation molding device, it is immediately placed in its place. The purpose is to enable efficient charging of coal cake into a coke oven by making it possible to place empty cases in the air and handling the cases three-dimensionally. .

The configuration of the compression molded coal case operating station in a coke oven according to the present invention will be explained in detail based on an embodiment shown in FIGS. 2 and 3. .

The trolley is equipped with a device C that can move in the direction of a and that can charge only the compressed briquette (coal cake) g in the compression briquette storage case E received on the trolley into the furnace chamber A' of the coke oven. From one end of the extruder yard 1, where the compression-molded coal charging trolley is installed, to the vertical side A of the coke oven A.
A machine stand F is installed perpendicular to the rail a, a compression molded coal storage case E is placed on the machine F so as to be orthogonal to the rail a, and a nuclear machine stand FK is installed in the case E. A case extrusion device H is provided which can transfer the case E onto the trolley tls perpendicular to the rail a, and above the machine F, the case E can be lifted and lowered by horizontally gripping it, and the case pusher H can be moved in the direction of the rail a. A hoisting machine, such as a ceiling hoist (2), which can be displaced while perpendicular to the rail (a), is installed in the hoisting machine.

In the above, the compression molding carbonate mold device G is shown in FIG.
As shown in FIG. 3, coal is supplied to the coal charging chamber 2 from a popper 3, and the coal charging chamber 2 has a pusher 5 that can be horizontally reciprocated by a fluid-driven cylinder 4. The coal supplied to the coal charging chamber 2 is compression-molded by the presser 5, and then pushed out toward the compression-molded coal storage case E which is disposed following the coal charging chamber 2. E is designed to be filled with coal cake g. Note that 6 indicates a cutting device that cuts a series of compression molded coals along the end surface of the case E. Furthermore, in the case E, the coal (coal cake) g compressed and molded by the end face of the case has the shape of one furnace chamber A' of the coke oven A.

It is shaped to fit the size.

The compression molded coal storage case E is a rectangular hollow body, as shown in FIG. , can be freely entered and exited from the case E, and the openings on the lateral sides are compatible with the openings of the charging chamber 2 of the compression molding carbonation molding device G and the furnace chamber A' of the coke oven A. In this way, one end of the receiving plate e at the bottom can be engaged with one end of a ring belt type drive band 7 forming a compression molded coal charging device C of a compression molded coal charging trolley to be described later. It looks like this. Note that 8 indicates a drive gear for the drive band 7.

Furthermore, as shown in FIG. 2, the compression molded coal charging trolley has an upper surface that engages with one end of the receiving plate e at the bottom of the compression molded coal storage case E. It is equipped with a ring belt type drive band 7 which can feed the gas into the furnace chamber A' from the inside of the case, and 9 indicates a drive motor. Reference numeral 11 in each figure indicates a furnace lid removing device in the furnace chamber.

The above-mentioned ceiling hoist (2) has running rails (14, 14) parallel to the rail (a) on a plurality of pillars (13) erected around the machine platform (F).
A girder 15 was placed over the running wheels 14 and 14, and on the girder 15, a pair of drums 17 and 17 for rolling soil with tongs I6 capable of gripping the case E was installed. It is something.

There is no restriction on the type of hoisting rock as long as the case E can be held horizontally in a state perpendicular to rail a, raised and lowered, and displaced in the direction of rail a.
It is illustrated as an example. Examples other than the ceiling hoist include an empty case operating device that lifts an empty case with a hoist, displaces the hoist with a pusher, and lowers the empty case to a predetermined location.

Since this embodiment has an inclined configuration, coal is first introduced into the coal charging chamber 2 from the hopper 3 of the compression molding carbonation mold device G, and then the fluid driven cylinder 4 is actuated and the coal is introduced using the pusher 5. Coal is compression-molded and extruded and filled into compression-molded coal storage case E, and this operation is repeated. When a coal cake g cut to the required length is formed in case E, the case extrusion device I] is activated, and one end of the receiving plate e in the predetermined position on the compacted coal charging trolley D, which is waiting on the side of the machine F, that is, the case E, pushes the receiving plate e. The compression molded coal is pushed out to a position where it can engage with the drive band 7 of the compression molded coal charging device C, and then the compression molded coal charging trolley is moved into the desired furnace chamber A.
