Description
Technical field
The utility model relates to a kind of blowing-type sintering machine, is the special equipment with the artificial agglomeration of Iron Ore Powder of iron-smelting process raw material preparatory stage in early stage.
Background technology
Employed sintering machine mainly is a chain type down draft sintering machine in the present domestic iron making and sintering technology.The structure of chain type down draft sintering machine mainly comprises distribution device, igniter, main frame and wind power system, also have servicing units such as dustproof dust arrester, feeding system and discharge system in addition, wind power system mainly is made of the pipeline of exhausting blower fan, exhausting bellows and connection blower fan and bellows, and the exhausting bellows are distributed near the position of main frame chassis.Motor moves along track continuously by the chassis of actuator drives main frame; Distribution device with the material that mixes equably cloth on chassis; When material enters pyrogen igniter with chassis, material bed top is at first lighted, after this material enters the exhausting zone with chassis, the wind-force that exhausting system provides blows along direction from top to bottom, because the effect of wind-force, burning zone progressively enlarges from top to bottom, when material will arrive main frame not during portion, whole all burnts.In whole combustion process, Iron Ore Powder produces chemical reaction and fusing through high temperature action, condenses in temperature changing process, and formation is block, reaches the sintering purpose.The wind power system of this exhausting formula sintering machine adopts the exhausting mode, so power consumption is big, and equipment investment is big, and the construction period is long.In addition, owing to adopt the exhausting mode, make chassis and grid section be in the high-temperature region for a long time, chassis and grid section must adopt the heat-resisting ductile iron material, the also easily sticking grid section of agglomerate, therefore, grid section spoilage height, 1.4 kilograms of grid sections of general one ton of sintering deposit loss; What the main air blower of down draft sintering machine was pumped is the high temperature sintering flue gas, so the main air blower rotor pole is fragile, the life-span of main air blower rotor generally has only 4-12 month.
Summary of the invention
Therefore the purpose of this utility model provides a kind of new blowing-type sintering machine, and this sintering machine power consumption is little, and can effectively reduce the spoilage of grid section and blower fan.
The purpose of utility model realizes by following mode.
The blowing-type sintering machine, comprise distribution device, igniter, main frame and wind power system, wind power system mainly is made of the pipeline of blower fan, bellows and connection blower fan and bellows, at least one air blast blower fan is arranged in the wind power system, the bellows that are connected with the air blast blower fan are air blast bellows, and the air blast bellows are distributed in the below of main frame chassis.
Motor moves along track continuously by the chassis of actuator drives main frame; Cloth is on chassis equably at twice with the material that mixes for distribution device, and the amount of cloth is less relatively for the first time, and the amount of cloth is bigger for the second time; The burner point coal gas of igniter remains on more than 1000 degree igniter temperature; When the good material of first substandard cloth enters pyrogen igniter with chassis, this material bed being lighted, coal dust firing in the compound, reach the igniting purpose, behind the bed of material process igniter of lighting, when arriving the secondary material distributing position, distribution device carries out the cloth second time on a bed of cloth, the thickness of secondary material distributing layer is the 180-300 millimeter, after this material enters the air blast zone with chassis, blower system has 8-10 air blast bellows to be evenly distributed on the chassis below, the wind-force that blower system provides blows along direction from top to bottom, because the effect of wind-force, the bed of material of having lighted is burning upwards, and burning zone progressively enlarges from top to bottom, when material will arrive the main frame afterbody, whole all burnts.In whole combustion process, Iron Ore Powder produces chemical reaction and fusing through high temperature action, condenses in temperature changing process, and formation is block, reaches the sintering purpose.
The blowing-type sintering machine that the utility model provides has following advantage:
1, power consumption reduces greatly, and energy-saving effect is remarkable, and the power consumption of exhausting formula sintering machine is generally sintering deposit power consumption 33-39Kw.h per ton, and the power consumption of blowing-type sintering machine is generally sintering deposit power consumption 20-22Kw.h per ton.
2, cost and small investment, the construction period is short, and the blowing-type sintering machine is the 1/2-3/5 of exhausting formula sintering machine investment, and the construction period of producing 300 tons blowing-type sintering machine daily is about four months, and the construction period of exhausting formula sintering machine is about 1 year.
3 and can effectively reduce the spoilage and the fault rate of part of appliance, improve the service life of blower fan and host part, save maintenance cost, reduce production costs.The main air blower of blowing-type sintering machine is the air blast blower fan, conveying be fresh cold air, less to the influence of draught fan impeller, so the spoilage of blower fan is extremely low, fan life is more than 10 years; The chassis of blowing-type sintering machine and grid section are in the air blast low-temperature space, and its material adopts plain cast iron to get final product, and the life-span is more than 3 times of exhausting formula sintering pallet and grid section.
4, owing to adopt the air blast mode, the pollution level of blowing-type sintering machine reduces greatly, and its environmental protection index can reach three class regional standards.
