Abstract
Description
Technical Field
[0001] The utility model belongs to the field of metal smelting equipment, and specifically relates to a lime powder conveying device. Background Art
[0002] During the sintering process, lime powder reacts with substances such as iron oxide and quartz in the sintered ore to form molten calcium silicate, which fills the pores in the sintered ore, thereby improving the strength and durability of the sintered ore. During the sintering process, lime powder can absorb harmful substances such as sulfur dioxide in the flue gas, thereby reducing the occurrence of environmental problems. Lime powder can decompose into calcium oxide and carbon dioxide at high temperatures, releasing a large amount of heat, thereby reducing the fuel consumption of the sintering furnace and saving energy.
[0003] During the sintering process, lime powder is pumped into the conveying pipeline through a material pump and transported to the sintering position. As the use time increases, the pipeline will become scaled and thinner. After the pipeline is scaled and thinner, the lime powder transportation will slow down, the transportation time will become longer, the transportation pressure will increase, and the transportation efficiency will become lower. If personnel are not organized to dredge, it will cause the inability to transport lime powder and the amount of lime powder used for sintering cannot be guaranteed. In the existing technology, lime powder with smaller particle size is used, and lime powder with fine particle size (200 mesh) is generally selected. After long-term use, the conveying pipeline of lime powder with smaller particle size will also become clogged. Even if blockage occurs, it is still inevitable to organize personnel to clear it; when organizing personnel to clear the blockage, the operator must climb to a pipe more than 10 meters above the ground to find the blockage section of the pipe caused by scaling, cut off the blocked part of the pipe, and use water and gas cutting to perform alternating hot and cold reactions on the scale, and slowly clean it. The cleaning time of a pipeline can be as short as eight hours or as long as four or five days, which is time-consuming and labor-intensive. Moreover, most of the ash conveying pipelines are above the gas pipelines, and gas cutting and electric welding are needed for clearing the blockage. Not only is it high-altitude work, but it also involves work near the gas pipeline, which has a high risk factor. Utility Model Content
