In the using process, the material cleaner for the cylinder of the mixer is fixed and the cylinder of the mixer rotates ceaselessly so that the scrapers scrape materials easy to agglutinate at the feed inlet end of the cylinder.
Description
Technical field
The utility model belongs to the Iron and Steel Production mechanical field, is specifically related to a kind of Iron and Steel Production facility, particularly a kind of mixer cylindrical shell material-clearing device.
Background technology
Iron and steel is the alloy that iron and carbon, silicon, manganese, phosphorus, sulphur and a spot of other elements are formed.Wherein, outside the deironing, the content of carbon plays a key effect to the performance of iron and steel, so be called iron-carbon alloy again.The main production process of modern steel integrated complex is divided into two types: long flow process and short flow process.Long flow process is used the widest at present; Its process characteristic is: the iron ore raw material adopts blast furnace to produce molten iron, after Molten Iron Pretreatment after oversintering, pelletizing are handled; By pneumatic steelmaking, external refining to qualified composition molten steel; Be cast into difform strand by continuous casting, be rolled into all kinds of finished products, the iron and steel enterprise in the whole world about 70% takes this flow process to produce; Short flow process can be divided into two types again according to raw material; One type is iron ore behind direct melting and reducing, adopts electric furnace or pneumatic steelmaking, and its main feature is; The iron ore raw material is handled without sintering, pelletizing; Do not have the blast furnace ironmaking production link, this flow process is used less at present, accounts for below 10% greatly; Another kind of be with steel scrap as raw material, after melt smelting by electric furnace, get into subsequent process; There is not the blast furnace ironmaking production link yet; This technological process accounts for 20%, and in order to enhance productivity, domestic and international many steel plant also take to convert the technology of hot metal charging in electric furnace smelting at present.
In general, the production procedure of iron and steel comprises flow processs such as sintering, ironmaking, steel-making, continuous casting, steel rolling.Sintering is exactly iron mineral powder agglomeration, and for blast furnace provides a kind of method of fine fodder, it is to utilize Iron Ore Powder, flux, fuel and return mine and process a process of block raw materials for metallurgy by a certain percentage.The process of ironmaking is exactly the liquid pig iron that temperature and composition meet the requirements that obtains with the iron ore economical and efficient; Realize this process through blast furnace process; May be summarized to be: under the condition of low-energy-consumption of trying one's best; Through the reverse movement of controlled furnace charge and coal gas stream, processes such as high efficiency completion reduction, slag making, heat transfer and the reaction of slag iron obtain the comparatively desirable liquid metal product of chemical composition and temperature.Blast furnace burden is produced qualified molten iron through various chemical reduction reaction and is sent into steel-making through the torpedo jar then, goes into converter smelting Cheng Gang as steelmaking feed then.Slag enters slag bath through flush slag, separates through pulp water, and slag is drained, water circulation use.The byproduct that produces in the blast furnace ironmaking process---blast furnace gas is as uses such as low calorific value gas fuel heat supply wind furnace, sintering, boiler, preheating furnace and heating furnaces.Steel-making is meant that impurity such as carbon too much in the raw material (molten iron and steel scrap etc.), sulphur, phosphorus remove and add the process of the alloying component that adapts to.Continuous casting is meant molten steel in pans inject with water-cooled crystallizer continuously, behind the base shell that congeals into, pulls out with stable speed from crystallizer, through the water spray cooling, after treating all to solidify, is cut into the continuous casting billet of designated length again.Steel rolling is meant that the steel ingot that continuous casting comes out rolls into all kinds of steel with the hot rolling mode at different rolling mills with continuous casting billet, forms the process of product.
Trommel mixer is the steel works sintering operation mixing apparatus that arrives commonly used.Its operation principle is: after various raw materials for sintering got into mixer, material rotated with mixer, motion under effects such as centrifugal force, frictional force and gravity, and each component is admixed mixing mutually.Because all there is certain viscosity in various materials, very easily stick to the feed end drum surface, cause machine utilization to increase, and power consumption rise.Cause blending space to diminish like this, the mixing effect descends, and material is in cylindrical shell internal congestion, spreading, often dug material by forced-stopping machine.
The utility model content
To the deficiency of above-mentioned technology, the utility model provides a kind of simple in structure, the tangible mixer cylindrical shell of result of use material-clearing device, and it is made up of support, outrigger and scraper; Support is positioned at the outside of the feed end of mixer cylindrical shell; And with mixer cylindrical shell independent separate, outrigger one end is fixed in the support middle position, the outrigger other end is provided with scraper; Scraper is fixed on the outrigger through welding manner, and the quantity of described scraper is 4-8.In use, mixer cylindrical shell material-clearing device is fixed, and through the continuous rotation of mixer cylindrical shell, scraper scrapes off at the ore deposit of bonding the cylindrical shell feed end easily.
Consider the energy consumption of scraper generation and the operating efficiency after the combination of all scrapers, the utility model has also carried out preferably the quantity and the spacing between the scraper of scraper, and preferably, the quantity of described scraper is 6.In addition; Consider the caking property and the bonding amount of material; The utility model minimum near the spacing between two scrapers of the feed end of mixer cylindrical shell; The closely combining of this two scrapers can guarantee to be scraped off as early as possible near the binding material of the feed end of mixer cylindrical shell, thereby improves whole clear material speed and the efficient to the mixer cylindrical shell.
After the utility model adopts said structure; Through install the mixer cylindrical shell material-clearing device of the utility model at mixer cylindrical shell feed end; Avoided material in cylindrical shell, to bond and caused regular phenomenon of being dug material, thereby improved the equipment life cycle, and improved productivity effect by forced-stopping machine.
The utility model mixer cylindrical shell material-clearing device, the utilization U-steel is built support, as outrigger, on outrigger, welds scraper according to the cylindrical shell concrete condition with I-steel again.The making tube list of this structure, and easily assembling can be saved the more repair time, have importantly improved whole sintering work rate, and result of use reaches the expection requirement.
