Description
Technical Field
The invention relates to the field of material drying, in particular to a lump ore dryer with a three-section detachable lifting plate.
Background
Lump ore is of various types, different quality, influenced by rain and snow weather, and partial lump ore contains that the powder content is many, moisture is big or viscosity is high, no matter which kind of lump ore shale shaker of use, all probably because of the silo mouth does not unloading or the screen cloth space is stuck by the powder, leads to the unable screening of lump ore or the screening effect is not good, restriction blast furnace use.
At present, the ore blocks fed into the furnace generally have high viscosity and high powder content, particularly, the water content of the ore blocks imported overseas generally reaches about 6 percent, and the powder content reaches more than 20 percent. Due to the facts that materials are conveyed by water, the conveying distance is far, logistics links are many, open-air stacking is carried out in the turnover process, and damage is increased when the materials are conveyed and loaded, the powder content of lump ore is even higher than 30%. Meanwhile, the increase of water content of the lump ore causes a large amount of powder to be adhered to the surface of the lump ore, a screen plate of the vibrating screen is often blocked during screening, and the screening effect cannot be achieved, so that the powder ore adhered to the surface of the lump ore finally enters the blast furnace, the air permeability of the blast furnace is influenced, the smelting cost of the blast furnace is increased, and the stable smooth operation of the furnace condition of the blast furnace is also influenced.
At present, most steel enterprises directly adopt a vibrating screen screening process, the method is used more in northern steel enterprises, screen plates of vibrating screens are not easy to block in dry weather, the screening efficiency is high, the yield can be kept in a less rainy day all the year round, and the investment, operation and maintenance cost is lower. A vibrating screen water washing process is adopted by a small part of iron and steel enterprises, spray heads are arranged on the upper portion and the periphery of a vibrating screen, lump ores at the feeding and discharging positions of a belt in the screening process are washed, and powder ores adhered to the surfaces of the lump ores can be effectively screened and cleaned. However, the environment is poor due to the fact that washing water splashes, screening and transporting equipment is seriously damaged, sewage needs to be treated by a complete system, the engineering occupied area is large, the investment is high, and the operation and maintenance cost is several times higher than that of a vibrating screening process.
With the development of the iron-making blast furnace operation technology and the requirement of high-efficiency economical production of iron-making, the charging proportion of blast furnace lump ore is higher and higher. Because the lump ore as a high-quality iron-containing raw material can be directly put into a furnace for smelting, not only can the agglomeration process and the energy consumption of the agglomerated pellet be saved, the pollution of the agglomerated pellet process to the environment is effectively reduced, but also the domestic and foreign iron ore resources can be fully and reasonably utilized, the TFe content of the lump ore imported from abroad is higher, the charging proportion is improved, the charging grade is favorably improved, particularly when the market price of the lump ore is reasonable, the charging of the lump ore into the furnace is increased as far as possible, the iron-making cost is reduced, and the technical and economic indexes of blast furnace iron-making are improved.
For example, chinese patent publication No.: CN203526070U, published: 2014.04.09 discloses a low-cost lump ore drying and screening system for iron making, which comprises: the dryer is used for drying the wet lump ore and comprises a feed inlet for inputting the wet lump ore and a discharge outlet for outputting the dry lump ore; and the vibrating screen is connected with a discharge port of the dryer and is used for screening dry lump ores. The utility model discloses a can solve the screening problem that contains the high lump ore of powder moisture to simple process, investment cost is few, and the working costs is low. However, the utility model discloses a dry to lump ore with hot-blast, the hot-blast effect of material of bottom can not be arrived, and it is inhomogeneous to dry, and the effect is difficult to guarantee, and does not adopt the drying-machine that is used for lump ore stoving specially and supporting special heat source, and the system has certain limitation, and blast furnace lump ore uses and does not possess the scale condition, and especially the ability of online continuous supply with large-scale blast furnace lump ore can't realize.
For example, chinese patent publication No.: CN205119745U, published: 2016.03.30 discloses a blast furnace lump ore complete drying device. The method can realize the drying and screening of the blast furnace lump ore by the vibrating screen before the blast furnace lump ore enters the blast furnace ore groove, thereby greatly improving the air permeability of the blast furnace, saving energy, reducing consumption, reducing the smelting cost of the blast furnace, reducing the operation difficulty of the blast furnace and ensuring the stable and smooth operation of the furnace condition. It only says that screening is carried out after drying, how drying is lack of description, how drying efficiency is improved is not described, and the two patent documents adopt vibrating screen screening, so that no solution is provided for avoiding the blocking of the vibrating screen by sticky materials, and no technical scheme is provided for improving the drying efficiency of lump ore. The above problems still remain.
