Description

Technical Field

[0001] The utility model relates to a nodule treatment device for an ignition furnace of a sintering machine, belonging to the technical field of ignition furnace technology for sintering machines in the metallurgical industry. Background Art

[0002] The sintering ignition furnace is an important process equipment in the sintering production process. The ignition furnace is designed in front of the distributor, and the burner is located above the trolley. After the sintering mixture is distributed to the trolley, it needs to pass through the ignition furnace to ignite the material surface and start the exhaust sintering process. In order to reduce gas consumption, most ignition furnaces are designed with a lower furnace, and at the same time, sintering pursues thick and ultra-thick material layers. During the ignition process of the ignition furnace, due to flame scouring and surface raw fuel explosion, materials will splash onto the lining of the ignition furnace. Since the temperature on both sides of the ignition furnace is relatively low, the splashed materials will cool on both sides to form nodules. The nodules will continue to enrich in continuous sintering production and continue to grow inward on both sides, affecting the ignition on both sides of the trolley, resulting in more raw materials on both sides of the trolley, which directly affects the quality of the sintered minerals. The growth and enrichment of nodules can also easily cause the trolley to fall off, shortening the service life of the ignition furnace.

[0003] At present, the treatment methods of nodules in the ignition furnace of sintering machines are divided into online and maintenance treatment. The method of online nodule treatment is generally to place larger and heavier foreign objects on one side of the nodule material surface. During the forward movement of the trolley, the nodules are caused to fall off by the collision of the trolley. This method has poor treatment effect and cannot be accurately treated; the maintenance nodule treatment method is to wait for the ignition furnace to cool to a suitable temperature during maintenance, and then the personnel will use tools such as electric picks or crowbars to handle it. This method has problems such as high labor intensity, poor working environment, failure to handle in time, and damage to the lining. Therefore, it is necessary to design a nodule treatment device for the ignition furnace of a sintering machine. Utility Model Content
