Description
Technical field
The utility model belongs to Ferrous Metallurgy steelmaking technical field, specifically a kind of material screening device being applied to material process alloy baking kiln.
Background technology
Ferroalloy is widely used as the raw material that pneumatic steelmaking is important, now develops polytype, as alloys in common uses such as silicomanganese, ferrosilicon, ferrochrome.But in the handling of these ferroalloys, transhipment, shattering process, create a certain proportion of alloyed powder face, because the proportion in powder face is less, in deoxidation alloying process, all as bulk alloy can not enter molten steel inside, the slag blanket in ladle that is easy to float is burnt on the surface.Because powdery alloy is easily burnt, the powdery alloy added on the one hand causes waste, the more important thing is that it can affect the addition of alloy in molten steel, thus can affect the quality of steel.If increase the addition of alloy in advance, the smelting cost of steel can be increased.
Summary of the invention
The purpose of this utility model is the alloy screening plant providing a kind of structure simple, easy to operate, reduces the scaling loss of alloy in molten steel, improves the smelting quality of steel.
The utility model realizes like this.It comprises alloy storage bin 1 and alloy baking kiln owner body 5, it is characterized in that: an alloy vibratory sieve 2 is installed between alloy storage bin 1 and alloy baking kiln owner body 5, the charging aperture of alloy vibratory sieve 2 engages golden storage bin 1, and the outlet of alloy vibratory sieve 2 engages the alloy receiving opening 4 of golden roasting kiln main body 5; Form with alloyed powder face gathering-device 7 below alloy vibratory sieve 2 compass screen surface.
Because the utility model increases vibratory sieve and alloyed powder face gathering system thereof on the basis of original alloy baking kiln, after alloy raw material flows out from alloy storage bin, through bolting, alloyed powder material screen is branched away, and reclaimed by powder face gathering-device.Alloy raw material after screening enters roasting kiln from receiving opening and toasts.Alloy raw material, through the screening of screening plant, reduces on the one hand the powder face rate using alloy, improves recovery rate of iron, and the waste avoiding alloy powder is on the other hand fallen, low production cost.The utility model technique is simple, reasonable in design, can meet the technological requirement of material process alloy screening.After invention, this kind of alloy screening plant achieves the object improving recovery rate of iron and cost efficiency smoothly.

Detailed description of the invention
The utility model comprises alloy storage bin 1 and alloy baking kiln owner body 5, an alloy vibratory sieve 2 is installed between alloy storage bin 1 and alloy baking kiln owner body 5, the charging aperture of alloy vibratory sieve 2 engages golden storage bin 1, and the outlet of alloy vibratory sieve 2 engages the alloy receiving opening 4 of golden roasting kiln main body 5; Form with alloyed powder face gathering-device 7 below alloy vibratory sieve 2 compass screen surface.
The compass screen surface of alloy vibratory sieve 2 can adopt traditional strip, square, rhombus, polygon sieve aperture, in order to prevent bulk alloy to the impact of compass screen surface, the utility model preferably adopts following structure: the compass screen surface structure of alloy vibratory sieve is followed successively by alloy vibratory sieve material feeding buffering area 8, alloy vibratory sieve trapezoid sieve region 9 and alloy vibratory sieve discharging buffering area 10, to improve screening quality from import to outlet.
Collect for the ease of the alloy after screening, to the pollution of environment when preventing alloy material from toasting, be incubated and be convenient to check roasting kiln inner alloy state, an alloy receiving opening removable cover 3 is installed on alloy receiving opening 4.
During use, alloy storage bin 1 and alloy vibratory sieve realize chain control by objects such as vibrating motors, and namely alloy starts vibratory sieve from storage bin blanking and automatically opens and start screening.Alloy first blanking to vibratory sieve buffering area 8, due to effect of vibration and natural slope, alloy can successively through trapezoid sieve region 9 and discharging opening buffering area 10, complete alloy screening process, wherein trapezoid sieve part is by round steel apart from one another by being welded on two-layer or two-layer above bucking ladder, and bucking ladder difference in height is 8-10cm, completes twice screening successively during alloy screening by two-layer bucking ladder, whole trapezoid sieve is closed state substantially, reduces dust raising phenomenon in screening process; Have removable cover 3 above receiving opening 4, effect is insulation and is convenient to check roasting kiln inner alloy state.The alloyed powder face that screening produces is recycled to gathering-device 7, and transports recovery in time.Alloy after screening enters alloy baking kiln 5 from receiving opening and carries out high-temperature baking, toasts complete alloy and transports from discharging opening 6 releasing.
