Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust collector for a coke guide vehicle, and more particularly, to effectively collect dust and smoke when pushing coke from a coke oven carbonization chamber. The present invention relates to a dust collecting device for a coke guide vehicle that is capable of collecting dust and is compact in structure.

[0002]

2. Description of the Related Art Generally, coke as an auxiliary raw material for a blast furnace is produced by carbonizing carbon in a coke oven installed in a steel mill.

The coke oven mainly comprises a carbonization chamber and a heat storage chamber. Coal as a coke raw material, that is, coking coal, is charged into the carbonization chamber through a coal car and is heated and carbonized by combustion of air and blast furnace gas in the carbonization chamber to produce coke.

The coke that has been dry-distilled is extruded from the kiln opening of the carbonization chamber by an extruder into a coke guide wheel through a passage between a pair of guideways. That is, after the completion of carbonization, the pair of sideways of the coke guide vehicle approach the kiln opening of the carbonization chamber, and the extruder passes through the passage between the sideways to make the coke.
The cous is extruded.

A lot of dust and smoke are generated during the coke extrusion. However, in the dust collector of the conventional example, there are many leaks from around the dust collecting hood at the upper part of the sideways and near the kiln mouth of the carbonization chamber, and sometimes dust is not concentrated. The dust collection efficiency is extremely low.

That is, when the coke is extruded, a large amount of dust or smoke is generated at the kiln opening of the carbonization chamber or the fire engine. Dust from the fire extinguisher occurs when the coke is delivered to the bucket car.
However, this dust generation is due to the maintenance of dust collection equipment around the coke oven,
It has decreased considerably due to improvement.

Regarding the dust generation around the kiln mouth of the coke oven, various peripheral facilities have been improved, but this does not reduce the amount, and further improvement is desired.

[0008] In short, the dust around the kiln mouth of the carbonization chamber is more noticeable than that of fire-extinguishing vehicles, etc., which is considerably reduced. From this point, effective dust collection around the kiln mouth of the coke oven is possible. Measures are required.

From this point of view, for example, Japanese Utility Model Laid-Open No. Sho 63-149.
The dust collectors described in Japanese Patent No. 944 and Japanese Utility Model Laid-Open No. 63-149945 are proposed.

The dust collectors described in these publications are
A seal brush, a flexible sheet, or the like is attached to the tip of the guide wheel, and the seal brush and the back sheet supporting the furnace lid are sealed by these.

In this dust collector, a seal brush or the like seals between the guideway that advances when the coke is extruded and the backstay of the coking chamber kiln, so that the coke
Dust is suppressed to some extent during extrusion.

However, the back stay supports the furnace lid and is always exposed to high temperatures during the operation of the coke furnace. For this reason, the backstain is thermally deformed with repeated use, and conversely, the seal brush is also thermally deformed, so that the sealing effect is lost over time, and dust may be leaked, which is preferable. Absent.

In the upper part of the guideway, the dust is sucked by the suction connector after passing through the dust collecting hood, but dust is often leaked between the suction connector and the dust collecting hood.
For this reason, it is difficult to concentrate dust only with the suction connector corresponding to the guideway from which the coke is extruded, and the generated dust and smoke can be collected even with the connector adjacent to the corresponding suction connector. It is not preferable because it is sucked.

[0014]

SUMMARY OF THE INVENTION The present invention is intended to solve the above-mentioned drawbacks, and more specifically, it is a collection of a coke guide vehicle capable of effectively preventing dust generation in the vicinity of a kiln mouth of a coke oven carbonization chamber. Propose a dust device.

[0015]

That is, the present invention is
In a dust collector for a coke guide vehicle that collects dust when pushing coke from a coke oven carbonization chamber through a pair of guideways, a coke oven is provided at the tip of each guideway. A first seal member whose tip is elastically pressure-bonded to the surface of the back stay supporting the furnace lid in the carbonization chamber is provided, and the tip is elastically attached to the heat insulating plate surrounding each guideway on the side surface of each guideway. It is characterized in that a second seal member which is crimped to is provided.

Further, the dust collecting hood arranged on the upper part of the guideway is extended to the suction connector side.

Therefore, the construction and operation of these means will be specifically described with reference to the drawings.

FIG. 1 is a side view of a dust collector according to one embodiment of the present invention.

FIG. 2 is a vertical sectional view of the dust collector shown in FIG.

FIG. 3 is an explanatory view of a dust collecting hood forming a part of the dust collecting device shown in FIG.

FIG. 4 is a transverse sectional view taken along the line AA in FIG.

FIG. 5 is an explanatory view showing an example of the second seal member of the dust collector shown in FIG.

First, in FIGS. 1 and 2, reference numeral 1
00 generally indicates a dust collector.

In the dust collector 100, the coke which has been carbonized from the inside of the carbonization chamber 1 of the coke oven is extruded toward the coke guide wheel by an extruder (not shown). The coke guide wheel is provided with a pair of guideways -21 (see FIGS. 4 and 5), and each guideway -21 is configured so as to be able to approach the kiln opening of the carbonization chamber 1 during coke extrusion. ,
The cast is extruded along the pair of guideways -21.

That is, when the coke is extruded from the carbonization chamber 1, the guideway -21 moves forward and contacts the kiln opening of the carbonization chamber 1 to extrude the coke.

In FIG. 1, reference numeral 3 indicates a fire engine. The fire extinguisher 3 is similar to the conventional example and does not form the subject matter of the present invention, and therefore its description is omitted.

Next, as described above, the first seal member 4 is provided at each tip of the pair of guideways 21 and 21 provided in the coke guide wheel so as to move forward or backward in the direction of the charring chamber kiln. Are provided (see FIG. 4).

That is, the first seal member 4 serves to prevent dust from being generated between the kiln opening of the carbonization chamber 1 and the tip portions of the guideways 21 and 21. When the guideways 21 and 21 are moved forward, the tip of No. 4 is crimped to the back station 5 holding the furnace lid. Therefore, the first seal member 4 is made of a plate-like material, which maintains a sealed state along the longitudinal direction of the kiln opening of the carbonization chamber 1.

Therefore, it is preferable that the first seal member 4 has elasticity or elasticity in order to maintain the sealed state, and a part or all of the first seal member 4 is a spring member. It can also consist of

In particular, as shown in FIG. 5, a curved portion 41 is provided to retain elasticity in a part thereof, while the distal end portion is curved to form a distal curved portion 42, which abuts against the surface of the back stay 5. At this time, it is preferable that the tip curved portion 42 is completely brought into close contact with the surface of the back stay 5.

The first seal member 4 is formed by each guideway 21 and
21 is attached to each tip, but the guide way 21
It is preferable that the guide beams 21 and 21 are not attached to the side beam 21, but are attached to the side beam 22 at the tip of the side beams 22 of the guideways 21 and 21.

That is, the pair of guideways 21 and 21
A high-temperature coke of red heat is accommodated between the guideways, so that the guideways 21 and 21 are affected by the red-hot coke and reach a considerably high temperature. Therefore, each guideway 21 and 21
If the first seal member 4 is directly attached to the first seal member 4, the first seal member 4 is exposed to heat, loses elasticity, and softens, which is not preferable.

Therefore, when the side beams 22 for supporting the guideways 21 and 21 are made of, for example, H-shaped steel, the first seal member 4 is attached to the web portion thereof. Such attachment is preferable because the degree of influence of heat on the first seal member 4 is reduced and the life is extended.

As described above, the pair of guideways 21 and 2
A heat insulating plate 6 for sealing the space between the tip of No. 1 and the kiln opening of the carbonization chamber 1 with a first seal member 4 and surrounding the guideways 21 and 21 to prevent the dissipation of heat. Second with 6
The seal members 7, 7 are provided and sealed by the second seal members 7, 7.

The second seal member 7 is made of a plate-like material which is elastic and elastic like the first seal member 4.

That is, as shown in FIG. 5, the second seal member 7 is provided with an elastic portion for retaining elasticity,
It is composed of a structure having elasticity.

The second seal member 7 is for each guideway-2.
1, 21 side beams 22, 22, for example, one end of a flange surface 221 of H-section steel forming the side beams is attached. The tips of the second seal members 7 are brought into contact with the inner surfaces of the heat insulating plates 6, 6.

In this case, each second seal member 7
The second seal members 7 may be provided at any positions as long as they are sealed between the guideways 21 and 21 and the heat insulating plates 6 and 6, but normally the heat insulating plates 6 and 6 are supported. Prop 6
1, 61, for example, the so-called wiper seals 62, 62 provided on the H-section steel forming the columns are preferably brought into contact with each other.

As described above, the guide rails 21 and 21 are moved by the first seal member 4 and the second seal member 7.
Seal between the tip and the heat shields 6 and 6 on its side,
While preventing dust generation from the kiln mouth of the carbonization chamber 1,
The dust generated when the coke is extruded is particularly effectively sucked by providing a dust collecting hood 8 (see FIG. 2) on the upper part of the guideway -21. To minimize the amount of dust generated.

As shown in FIGS. 2 and 4, when the coke is extruded, a part of the guideways 21 and 21 are advanced toward the kiln opening of the carbonization chamber 1, and a pair of guideways 21 and 21 are moved.
Extruded through 21. The dust collecting hood 8 on the upper part of the guideways 21 and 21 that moves forward or backward is extended to the corresponding suction connector 9. When the dust-collecting hood 8 is extended to the suction connector 9 in this way, the extended dust-collecting hood 8 ensures the smoke path to the corresponding suction connector 9 without leaking dust, etc. The dust collection can be sucked by the centralized suction connector 9.

In this case, in order to secure a concentrated flue channel by the dedicated connector 9, as shown in FIG.
A third seal member 10 is provided at the tip of the door 8 and the third seal member 10 is provided.
The tip of the rule member 10 is crimped to the kiln opening and the upper part of the kiln is sealed. The third seal member 10 is made of an elastic material similar to the first and second seal members 4 and 7.

That is, also in the conventional coke oven, dust generated during coke extrusion is suctioned and collected from the suction connector from the upper part of the guideway via the dust collecting hood. However, in the conventional example, the dust collecting flap above the guideway is
Since there is a gap between the cord and the suction connector, it is difficult to intensively suck dust by the corresponding suction connector corresponding to the guideway from which the coke is extruded. More specifically, since there is no seal between the suction connector corresponding to the guideway during the coke extrusion and the dust collecting hood, and there is a gap, dust and smoke are generated in the gap. Scatter from. Therefore, the scattered dust and smoke are also sucked from the suction connector adjacent to the corresponding suction connector, and the dust and smoke are dispersed, so that suction is concentrated and it is difficult to effectively perform the suction. This is a big problem.

On the other hand, as described above, the guideway
If the dust collecting hood 8 on the upper part of 21, 21 is extended to the suction connector 9 and the third seal member 10 is provided at the tip of the dust collecting hood 8, the guideways 21 and 21 Smoke and dust can be concentratedly collected at the upper part of the above, and can be concentratedly sucked only through the corresponding suction connector 9.
