Description

Colile filling wagons for coke ovens

The invention relates to a process on the furnace chamber, bar car for filling the coking coal in with Füllöff-. openings in the ceiling provided furnace chambers.

The filling openings in the oven roof are covered by lids closed. In all previously known devices for "filling in the coal, after removing the lid Filling pipes placed on the ceiling into which the outlets the container of the 'on the ceiling movable filling car flow out. After the filling, the filling pipes are lifted and then the filling openings through the lid again closed. When filling the coal and up to. If the lids are tightly seated again, filling gases escape, which cause considerable nuisance.

The connection of the filling pipes to a special suction system Hii "k cleaning and, if necessary, burning the resulting JFilling gases requires extensive additional Apparatus and only partially helps the gas nuisance away.

Another method involves trying to avoid the during during the filling of the coal released filling gases - supported by an ejector - to be sucked into the gas reservoir. After filling, the filling pipe is first removed from a filling hole and the lid is put on, then

109837/0151

this process is used one after the other for the other filling holes repeated. Han expects that the ' Ejector as much filling gas is sucked into the riser pipe, that just a filling hole can be kept open without Gas escapes into the atmosphere. This process is also cumbersome, time-consuming and prevents gas nuisance only partially.

It is the aim of the present invention to provide a device which can be moved on the furnace roof and is equipped with filling containers Train car so that the furnace chamber is filled and filled in a very short time with the least amount of equipment any nuisance caused by filling gas is suppressed.

The invention makes use of the phenomenon known per se that when a filling container is connected to a filler pipe a gas-tight, a fill gas nuisance excluding closure of the individual filling hole through the still above the same filler pipe is given if after filling the relevant section of the furnace in A sufficient amount of residual coal is left in the filling container.

According to the invention run by means of vertical traction means, z. B. by means of rods, lifting and lowering grippers for the filling hole cover in the telescopically extendable filling pipes, with the lower sleeves that surround the seat of the filling hole cover, which can be placed on the furnace ceiling in this way are that a gas-tight seal is formed; the uppermost position of the filling hole cover grasped by the gripper lies higher than the mouth; of the filling container into the filling tubes. The grippers can be used in a known manner Way be designed as an electromagnet.

ORIGINAL BATHROOM 109837/0151

The filling process plays with one that is designed in this way Filling wagons in the following catfish from:

The filling truck moves into such a position that the filling pipes stand exactly over your feet. These will with their cuffs placed on the oven ceiling, taking them create a gas-tight seal. Become a hundred the gripper lowered by means of the traction means within the filling tube; they grasp the lids and lift them up inside the filler pipes to above the mouth of the filler container. Now the filling begins.

Let us first assume that the transport of coal takes place from the container into the mouth of the filler tube by a known turntable or other conveying means. The container should contain so much coal that after filling in the amount intended for the filling hole in question, there is still a residual amount of coal above the mouth remains in the filler pipe, which represents a gas-tight seal.

After filling in the intended amount of coal, the Cover by means of the traction device, e.g. by means of a rod, inside the filler pipe on the gripper again lowered and placed gas-tight on the filling hole frame. Then the cover is released from the gripper, for example by an electromagnetic gripper Switching off the excitation current. .

This process can take place simultaneously with all the filling holes in an oven chamber. If all filling hole covers are in place, "the sleeves of all filling pipes can be raised and the filling carriage can move away.

If there is no mechanical means of conveyance available for transporting the coal from the waste container to the filling pipe, Rather, if the coal sinks due to its gravity (at), then, according to the further invention, the coal is kept opposite lift the filler pipe through its axis. and lowerable bell completed and the vertical, the gripper carrying traction means is so through the Bell performed that the gripper rests in its highest position on the underside of the bell.

In this design, the filling car is moved into the correct position with the bell closed the collar of the filling pipe is placed on the furnace roof, then by actuating the gripper the filling hole cover raised so far that it comes to rest under the bell. After that, this is combined with the one below located gripper is raised and so the coal flow is released. When the filling is finished, the bell becomes lowered into the closed position. The prerequisite here, too, is that there is still a residual amount of coal at the end of the filling process Remains in the container above the bell, which gives a gas-tight seal. Hach lowering the Bell in the closed position, the filling hole cover is now lowered by means of the gripper and the filling hole locked. After releasing the lid, the gripper is pulled up and the collar of the filling tube raised. The filling truck can now experience a great deal.

In order to ensure that the coal sinking into the filling pipe does not fall next to the filling openings and thereby the tight seal of the furnace chamber through the reopened JO put lid difficult, according to the further invention, a can be raised and lowered within each filler pipe Hopper provided: in its lowered position

109837/0151

should he take the shape of the mantle of a downward tapering Have a truncated cone and with its lower edge rest on the inclined surface of the filling hole frame; in raised Position he must clear the'cylindrical interior of the filler pipe, which is responsible for the vertical path of the " Füllochdeckels detected by the gripper is required.

In order to do justice to this double task, the as a truncated cone jacket, trained hopper made of several Sections that are divided by vertical cuts and only connected to one another at the upper annular edge are.

Means must be provided so that the im raised State initially vertically hanging down sections when lowering the hopper into the inclined position come, in which they form the shape of the intended truncated cone jacket, and the hopper with its lower Edge comes to rest on the inclined sealing surface of the filling hole frame. Such a means are ζ. B. guide body, which are arranged on the inner wall of the filler pipe and protrude inwardly in a wedge shape. Another means consists in the fact that in the wall of the lowerable collars of the filling pipes pressure pins over the circumference ' distributed, which, when the sections of the hopper come into their area, are moved radially inward and in this way the sections of the hopper into the Bring the incline with your lower edge on the filling hole frame rests.

In the accompanying drawings, several embodiments of the new filling car are shown, in one Detail showing the lower end of a filling container of a such a filling carriage, the filling

hole, and the filler tube shows. It is about vertical Sections, which are laid through the axis of the filling container and the filling hole, showing:

Fig. 1 is a vertical section through a! with the turntable at the bottom of the filling container

are arranged

Fig. 2 is a vertical section through a filling car, in which a Vibrating channel is provided,

3 shows a vertical section through a filling truck,

in which the filling container is closed by a bell that can be raised and lowered.

The same reference numbers indicate the same items in all figures.

The furnace ceiling is designated by 16, in which the filling hole can be seen. It is closed by a filling hole cover 5> the one on the inclined sealing surface 7 of a metallic Füllochrahmens 8 comes to rest. 5 a denotes the filling hole cover in the inserted position.

In any case, a filling container 1 is provided, the outlet 15 of which opens into a filling pipe 2. Located on this at the bottom there is a liftable and lowerable collar 3> which is outside the actual filling hole on the furnace ceiling, if accessible still on the outer edge of the filling hole frame 8 can be placed. The cuff is on all three arrangements only shown in the lowered position.

The essence of the invention make the gripper 4-, which one has to imagine as electromagnets and the means

109837/0151

a vertical rod 24 · can be raised and lowered can. You are able to lift off the filling hole cover and they are in a position above the outlet 15 to bring the filling container. Carriage of Coal in this run-out takes place in the arrangement according to FIG. 1 by a turntable 22, with the arrangement, according to! ig, 2 through a vibrating chute * 23 · The garbage bin 1 after the Fig. 3 has a frustoconical bottom, and the lower one Opening is completed by a bell 14- the. can be raised and lowered.

. So that the Eohle reaches the Fulloch 17 with certainty, liftable and lowerable hopper 6 \ are provided inside the filling pipes 2 * They are pulled out in the shown lowered position. Hit 6 a are the hoppers denoted in their raised position, shown in dash-dotted lines. Each of these hoppers is made of, for example, four vertical sections 21 which are separated from one another by vertical cuts 18. In the lowered position, these sections 21 form a downwardly tapering Eegel and lie with their lower edge 20 on the inclined 'sealing surface 7 of the filling hole frame 8. In the raised position - denoted by 6 a - hang the individual sections 21 loosely down. One has to imagine that on the upper hand 19 of the hopper 6 a pulling device attacks, which brings about the lowering and pulling up of the .Schütttrupers. Between the top edge and the inner wall of the cuff .3 are sealing elements 12 which ensure that the falling Eohle does not get into the annular space 9 remaining between the filling pipe 2 and the hopper 6.

109837/0151

In the arrangement according to FIG. 1, guide bodies designed as wedge pieces 10 sit on the inner wall of the filler pipe, which move the sections 21 of the hopper inward when they are lowered so that they are in the lowest Position to join together to form the truncated cone and the lower edge 20 on the inclined surface 7 of the sealing frame 8 rests.

In the arrangement according to FIGS. 2 and 3, the inward movement of the sections is carried out by pressure pins 11 which, for example be pressed inwards by compressed air cylinders or springs and in this way the sections 21 of the hopper 6 in the required inclined position. Their actuation is expediently automatic in connection with the lowering movement of the hopper.

In the arrangement of FIG. 3, the rod is 24-, on äer the gripper 4, which grips the filling hole cover 5, is passed through the bell 14. He is lying, as can be seen from Fig. 3, in the raised position on the underside of the bell 14-.

With 13 sensors are designated, which should then respond, when the state of. Coal in the filling container 1 has fallen below a certain level. There are already pulse generators known the when the filling of the filling container drops to a residual amount, which is still a conclusion of the filling container outlet guaranteed against the outside air, respond and, for example, an impulse to stop the turntable 22 (Fig. 1), to stop the vibrating channel 23 (Fig. 2) or to lower the bell 14 (Fig. 3).

Working with the new filling car takes place in such a way that the cuffs 3 are first put on, then

109837/0151

the filling hole cover 3 is lifted off by means of the gripper 4 and then the debris funnel 6 is lowered. Now either the mechanical conveying device (turntable 22, vibrating chute 23) is put into operation or - see FIG. 3 - the bell 14 is raised 3 the bell 14 is lowered, with the arrangement according to FIGS. 1 and 2 the turntable 22 or the vibrating chute 23 is stopped The rod 24 of the gripper 4 is lowered onto the filling hole cover 5. Once the filling hole cover 5 has been inserted, the gripper 4 is raised again and the cuff 3 is raised.
