Description

Light removal device with ventilation rod of sintering machine bogie {APPARATUS FOR REMOVING ATTACHED-DUST ON VENTILATING-BAR IN SINTERING MACHINE}

The present invention relates to a ventilation rod attachment light removal device of the sintering machine bogie, and more particularly to a ventilation rod attachment light removal apparatus of the sintering bogie that can effectively remove the adhesion light stuck to the ventilation rod.

In general, the sintering machine is the main equipment of the sintering plant that produces the sintered ore, the main raw material of the blast furnace.In the sintering machine charging device, the raw material is loaded into the sintering machine truck, and then ignited in the ignition furnace to drive the driving force of the driving sprocket. As a result, the sintering process proceeds while traveling to the light distribution unit. After the sintering is completed, the sintered ore is crushed and discharged from the crusher, and then the finished product is transferred to the blast furnace (not shown) through a separate cooling and particle size selection process.

The sinter recovery rate of the sintering machine is greatly related to the burning rate of coke in the sintering raw material, and the burning rate of the coke is greatly influenced by the amount of air passing through the blending raw material charged in the sintering machine bogie. Therefore, in order for the sintering reaction to proceed efficiently and to produce a good quality sintered ore, it is very important to secure the air permeability of the blended raw material so that an appropriate amount of air passes through the blended raw material layer.

As a conventional method for improving the air permeability of the blended raw material layer, a technique for reducing the aeration resistance of the blended raw material layer by the raw material pre-treatment method to increase the amount of quicklime to promote pseudo granulation and improve the strength of pseudo particles It is known, but it has a limit in improving breathability due to the limited amount of quicklime used.

In order to overcome this limitation, attempts have been made to improve ventilation by installing a ventilation rod inside the sintering device charging device to form a ventilation hole for ventilation in the lower layer of the blended raw material before ignition.

However, the technology for improving air permeability of the blended raw materials using the ventilating rod as described above results in non-uniform loading by distorting the path of the blending raw material to the sintering machine bogie due to the adhesion of light adhering to the outer surface of the venting rod and growing. There was a problem that caused a serious equipment accident that must be shut down.

In addition, when the adhered light adhered to the vent rod is not effectively separated, the volume of the vent rod is gradually blown outside, thereby increasing the air permeability for the blended material more than necessary. As a result, air enters the compounding material layer more quickly than necessary to increase the sintering speed. Accordingly, the sintered ore is not melted well.

In order to solve this problem, various techniques for removing the adhesion light attached to the ventilation rods have been introduced.

Korean Patent No. 10-0644520 (2006.11.2) discloses a "ventilating rod adjusting and cleaning device".

This is a technique of removing adherent light attached to the vent rod by a cylindrical scraper which is movable on the vent rod, thereby securing the air quality, thereby securing the quality of the sintered ore.

In addition, Korean Patent Registration No. 10-0644552 (2006.11.2) discloses a light removal device of the sintering device charging device.

The present invention relates to an apparatus for automatically removing adhesion light that is fixed and grown on the surface of a ventilation rod and adhesion light generated at the bottom of a guide chute by spraying high pressure water in order to secure air permeability of the blended raw material in the sintering process.

As described above, various techniques for removing the attachment light attached to the ventilating rod have been introduced. However, these methods have a physical impact on the venting rod to remove the attachment light, which causes the venting rod itself to wear out or the device malfunctions. After that, there is a problem that can not be continued cleaning.

On the other hand, although a method of applying the vibration to remove the adhesion light is also used, this method is because the ventilation rod is buried in the raw material, the vibration is not transmitted, the attachment light is not easily dropped, and the same impact on many ventilation rods There is a problem that is not easy to give.

It should be understood that the foregoing description of the background art is merely for the purpose of promoting an understanding of the background of the present invention and is not to be construed as adhering to the prior art already known to those skilled in the art.
