Description

Drive Sealing Device

The present invention relates to a driving unit sealing device for maintaining airtightness of a drive shaft portion passing through a driving unit, for example, a structure (container), and more particularly in a structure (container) such as a bin or hopper having a driving unit, for example, a screw feeder. The sealing of the part of the structure through which the drive part (shaft) of the screw feeder penetrates is effectively maintained, and in particular, it absorbs vibrations (vibrations) generated during driving, and in addition, wears through receiving (rotating) the rotation (force) of the ring structure provided to interlock with each other. It is related to the drive sealing device to maximize the sealing effect while suppressing.

Most of the molten iron produced in steel mills is produced by the blast furnace method of charging molten iron ore and coke made from bituminous coal into the blast furnace and reducing the iron to iron. By the way, such a blast furnace method has a problem in the facility investment and significant maintenance costs in the preliminary treatment of the raw material, such as coke or sintering equipment, and requires a separate facility for the treatment of pollutants.

Therefore, in the research and commercialization of molten iron manufacturing using molten iron ore which directly accounts for more than 80% of the world's ore production as a fuel and a reducing agent without pretreatment, and commercialization, or to improve productivity after commercialization. Much effort is being made on this.

For example, U.S. Patent No. 5,534,046 discloses a molten iron manufacturing facility using direct coal and spectroscopy, which is briefly described as a melt gasification furnace associated with a multi-stage flow reduction furnace in which a bubble fluidized bed is formed. Spectroscopy and subsidiary materials are charged into the first flow reduction furnace, and then go through a multi-stage flow reduction furnace, and the flow reduction furnaces are supplied with hot reducing gas from melt gasification, so that the spectroscopy and secondary raw materials at room temperature come into contact with the hot reducing gas. The temperature is raised and the reduced calcining spectroscopy and subsidiary materials are charged to the melt gasification furnace.

By the way. In the case where charged reducing iron and subsidiary materials are charged into the molten gasifier, it is necessary to secure the air permeability and liquidity of the coal packed layer in the molten gasifier, so that the molten gas is molded into a compacted body (lump) and charged into the molten gasifier.

On the other hand, a facility for compacting (briqueting) powdered iron and auxiliary raw materials and charging them in a molten gasifier is disclosed, for example, in US Pat. No. 5,666,638.

However, although not shown in a separate drawing, in the case of the drive shaft sealing of the screw feeder provided in the bin of the compacted body manufacturing facility of the molten iron manufacturing facility, for example, a sealing member such as an o-ring is simply in line contact with the drive shaft. Since the airtightness was maintained, there was a problem that the sealing property was difficult to be maintained stably.

In particular, as the drive shaft of the screw feeder is connected to a drive source such as an external drive motor, a considerable vibration (flow) is generated during rotational driving, resulting in a very short service life and a weak sealing property due to damage of the sealing member. In this case, there were various problems such as a decrease in the operation rate of the screw feeder.

Therefore, in the art, it is possible to effectively maintain the sealing of the structure portion through which the drive part (axis) of the screw feeder penetrates in a container such as a bin, hopper or the like having a screw feeder, in particular, which occurs during rotational drive of the drive part. There has been a need for a drive sealer that absorbs vibration (flow) and suppresses wear through rotational acceptance of ring structures that intersect with one another, while ultimately improving sealing.
