Description

Hopper device {HOPPER}

The present invention relates to a hopper device.

Generally, in the blast furnace, raw materials such as blast furnace are charged to produce molten iron. Here, since there is a certain pressure in the blast furnace, in order to charge the blast furnace into the blast furnace, the raw material is charged into the hopper connected to the blast furnace, and the raw material is charged into the blast furnace from the hopper.

On the other hand, when the raw material is fed into the hopper from the outside, there is a problem that the raw material can not be deposited uniformly in the hopper due to the weight difference or volume difference of the raw material itself.

An embodiment of the present invention is to provide a hopper device in which raw materials are uniformly deposited inside.

One aspect of the present invention relates to a hopper comprising a hopper body forming a space into which a raw material is charged and a hopper including an impingement plate located in a path through which the raw material is introduced in the space and including at least one depression recessed in a plane, Device.

The impingement plate may have a shape in which the width extends from the center to both ends in a plan view.

The impingement plate may further include a first protrusion protruding upwardly between the center and one end of the both ends and a second protrusion protruding upwardly between the center and the other end of the both ends have.

At least one of the first protrusion and the second protrusion may have a cylindrical shape.

The impingement plate may further include a guide portion protruding upward along the rim.

And at least one support for supporting both ends of the impingement plate within the space.

The impingement plate may slide along the support.

According to one of the embodiments of the present invention, there is provided a hopper apparatus in which raw materials are uniformly deposited inside.

1 is a cross-sectional view illustrating a hopper apparatus according to an embodiment of the present invention.

As shown in FIG. 1, the hopper device 1000 according to an embodiment of the present invention is connected to a blast furnace and feeds a raw material 10 such as a sinter or a coke into a blast furnace. The hopper apparatus 1000 includes a hopper body 100, an impingement plate 200, and a support 300.

The hopper main body 100 has two pairs, but is not limited thereto and may be one or more than three. The hopper main body 100 forms an internal space SP into which the raw material 10 is introduced. The raw material 10 is injected from the outside into the inner space SP of the hopper main body 100.

The impingement plate 200 is located in a path through which the raw material 10 is introduced in the inner space SP of the hopper main body 100 and includes a raw material 10 charged into the inner space SP of the hopper main body 100 from the outside, And the like.

As described above, according to one embodiment of the present invention, since the impingement plate 200 is positioned in the inner space SP of the hopper main body 100, the raw material 10 Collides with the collision plate 200 and is dispersed and deposited in the inner space SP of the hopper body 100 by the collision plate 200. [
