Description

Movable dust hood for molten iron ladle

Technical Field

The utility model belongs to the field of dust hoods, and particularly relates to a movable dust hood for a ladle.

Background

In general, iron and steel manufacturers have blast furnaces with different furnace volume specifications, such as ladles with various volume specifications, for example, ladles with the volume specifications of 40 tons, 60 tons, 80 tons and 90 tons, and the ladles with the corresponding specifications are respectively transported to corresponding steelmaking workshops to be charged for steelmaking, but the ladles and steelmaking cannot be completely matched due to uncertainty of blast furnace and steelmaking production in the actual production process, so that the ladles with small volume are transported to a large-volume converter or electric furnace, and the ladles are led to be combined into large ladles and then charged, or the ladles with large volume are transported to a small converter or electric furnace, and the ladles are led to be combined into small ladles and then charged, so that a procedure of combining or dividing the ladles is added, and a large amount of smoke dust is generated in the process of combining or dividing the ladles. At present, the dust collection in the process mostly adopts a fixed dust hood, and has the following defects: the fixed dust hood is limited by space greatly, and the ladle positioned ladle is difficult to be placed in the range covered by the dust hood completely, if the fixed dust hood is required to ensure that the ladle is placed in the range covered by the dust hood completely, a ladle plate hook-embedded inlet is required to be formed in the dust hood, so that flue gas overflow affects the dust removal effect and the factory environment.

Disclosure of Invention

The technical problems to be solved are as follows: aiming at the problems, the utility model provides a movable dust hood for a molten iron ladle, which solves the problem of difficult collection of flue gas caused by the fact that the molten iron ladle is not put in place.

The technical scheme is as follows:

in order to solve the technical problems, the utility model provides the following technical scheme:

a movable dust hood for molten iron ladle comprises an air pipe, a movable hood, a sealing baffle protection cover, a ladle and an electric butterfly valve; the tail end of the air pipe is connected with the dust remover, the air pipe is connected with the movable cover in a flush butt joint mode, and the electric butterfly valve is fixedly connected to the right side of the air pipe and used for controlling the opening and closing of the air pipe; the movable cover is divided into a fixed part and a movable part, the fixed part of the movable cover is integrally connected with the closed baffle, and the upper end of the movable part of the movable cover is connected with a track zipper; the protective cover of the sealing baffle is fixed on the inner side of the sealing baffle, and the position of the protective cover changes along with the change of the sealing baffle; the ladle is arranged inside the movable cover.

Further, the inner space of the movable cover is 6000 x 6300mm, the top elevation of the fixed part of the movable cover is 11850mm, the top elevation of the movable part of the movable cover is 14200mm, the width of the movable cover along the moving side of the air pipe is 6000mm, the lifting distance of the side is 2 meters, the lifting distance is 0.6-1 meter higher than the top of the water drum of the subway, the other side is taken as the molten iron pouring side, the width is 6300mm, the upper opening of the side is sealed to the position 1 meter below the cover edge, the lifting distance is 4 meters higher than the top of the water drum of the subway, and the side is sealed by a steel plate from the terrace to the upper 1-2 meters.

Further, the maximum distance between two ears of the ladle is 5243mm, and the upper opening is 5900mm-6500mm.

Further, the material of the sealing baffle protection cover is spray fireproof material or fireproof cotton.

The beneficial effects are that:

1. the movable cover is divided into a fixed part and a movable part, so that the movable cover can be suitable for ladles with different specifications;

2. the movable cover is flush and butted with the air pipe, so that smoke dust is effectively prevented from being discharged in an unorganized manner;

3. through the arrangement of the movable part of the movable cover and the sealing baffle, the smoke-free discharge and molten iron pouring can be synchronously realized.

Detailed Description

The following examples will provide those skilled in the art with a more complete understanding of the utility model, but are not intended to limit the utility model in any way.

Example 1

As shown in fig. 1, a fluidized bed electrochemical reaction system required for the present utility model was first established:

at a fixed molten iron ladle point, a movable dust hood for molten iron ladle comprises an air pipe 1, a movable hood 2, a sealing baffle 3, a sealing baffle protection cover 4, a ladle 5 and an electric butterfly valve 6; the tail end of the air pipe 1 is connected with the dust remover, the air pipe 1 and the movable cover 2 are connected in a flush butt joint mode, and the electric butterfly valve 6 is fixedly connected to the right side of the air pipe 1 and used for controlling the opening and closing of the air pipe 1; the movable cover 2 is divided into a fixed part and a movable part, the fixed part of the movable cover 2 is integrally connected with the closed baffle 3, and the upper end of the movable part of the movable cover 2 is connected with a track zipper; the sealing baffle protection cover 4 is fixed on the inner side of the sealing baffle 3, and the position changes along with the change of the sealing baffle 3; the ladle 5 is provided inside the moving housing 3.

The inner space of the movable cover 3 is 6 x 6.3 m, the top standard height of the fixed part of the movable cover 2 is 11.85 m, the top standard height of the movable part (movable smoke cover) of the movable cover 2 is 14.2 m, the width of the movable side of the movable cover 2 along with the air pipe 1 is 6 m, the lifting distance of the side is 2 m, the lifting distance is 0.6-1 m higher than the top of a subway water drum, the other side is used as a molten iron pouring side, the width of the side is 6.3 m, the upper opening of the side is sealed to the position 1 m below the cover edge, the lifting distance is about 4 m higher than the top of the subway water drum, and the side is sealed by a steel plate from the terrace to 1-2 m.
