Description
Technical field
The utility model belongs to ore weighing technology field, and the blast furnace multi-material related under a kind of concentrated weighing mode is got the raw materials ready system.
Background technology
In blast furnace under ore deposit groove concentrates weighing mode, be generally made up of equipment such as multiple ore storage bin and corresponding material feeder, vibratory screening apparatus, rotary conveyor, scale hoopers under groove, carried out the screening of ore and weighed.The coke that coke bin, ore bin disposing go out from groove, ore are transported in concentrated scale hooper by main haul belt, be transported to furnace roof, carry out cloth and enter stove by truck according to the batching material list program of setting.In recent years due to ore resource shortage problem, the iron ore kind that ironmaking enterprise uses gets more and more, and quality is different, for wine steel iron work, only pellet materials in 2011 just reach 13 kinds, and lump ore materials reach 7 kinds, and concentrate materials reach 8 kinds, for making blast furnace adapt to complicated crude fuel, after needing various mineral aggregate fully to mix, load blast furnace.
But adopt traditional program material list batching after concentrating the blast furnace under weighing mode to go into operation, the same time opens a scale hooper blowing and measures always.No matter be 4 car systems or 6 car systems, 2-3 car ore deposit is set at most in each program of material list, multiple ore deposit all cannot be set in a program, want polygamy material kind to arrange separately in other program, post operation personnel need in picture, manually to change material kind frequently, not only add the labour intensity of post work, and change material also may affect production not in time, nonetheless per car material is all single mineral, a various ore deposit point kind loads in batches, after uneven for quality mineral fully can not being mixed again cloth in burner hearth, it not the furnace charge after mixing, cannot provide potential of hydrogen rational crude fuel for blast furnace, have a strong impact on conditions of blast furnace and every economic and technical norms, such system, proportioning accuracy and cloth efficiency far can not meet the requirement of production.
Although operator skilled aborning can adopt manual mode to carry out multi-material mixing and get the raw materials ready, and operator must calculate the metering of each material kind, examine in melting process.So, first: the time of getting the raw materials ready will be increased largely; Second: the accuracy that cannot ensure each material kind proportioning; 3rd: the labour intensity virtually adding operator.Efficiency far of getting the raw materials ready like this can not meet the requirement of blast-furnace smelting.
Utility model content
The purpose of this utility model is for prior art Problems existing, provide a kind of weigh efficiency high and blast furnace multi-material under the concentrated weighing mode that tolerance range is higher is got the raw materials ready system.
For this reason, the utility model adopts following technical scheme:
Blast furnace multi-material under a kind of concentrated weighing mode is got the raw materials ready system, comprise belt conveyor, the top of described belt conveyor is provided with some ore bins along its length successively, feeding machine and ore vibrating sieve is provided with successively up and down between described ore bin and belt conveyor, described feeding machine and one_to_one corresponding identical with ore bin quantity with ore vibrating sieve, the below of described belt conveyor end is provided with ore and concentrates scale hooper, and described belt conveyor is connected with conveying belt motor.
Further, the side of described belt conveyor end is provided with coke bin, and the below of described coke bin is provided with coke vibratory screening apparatus successively and coke concentrates scale hooper.
Further, described system also comprises upper computer and PLC, and described PLC concentrates scale hooper to be connected with upper computer, feeding machine, ore vibrating sieve, conveying belt motor and ore respectively.
The beneficial effects of the utility model are: the concentrated weighing that can realize multi-material ore is got the raw materials ready, and can ensure the weighing precision of ore, meet the cloth requirement of the complicated furnace charge of blast furnace, effectively improve production efficiency and the quality of production of blast furnace; And the utility model system automation degree is high, labor intensity of operating staff is low, also has higher security simultaneously, and the problem such as windrow and electric equipment overload is less likely to occur.
Accompanying drawing explanation
