Description
Technical field
The present invention relates to a kind of blast furnace bell-less apparatus for distributing, especially a kind of blast furnace bellless distributor chute α angle lapping actuation mechanism.
Background technology
No charging bell at furnace top of blast furnace comprises distributor at present, corrugated tube, lower sealing valve, material flow gate, batch can, upper sealing valve, material stop valve and hopper, wherein distributor is the core component of whole plant, this equipment is arranged on the steel ring of furnace shell, its distributor chute working position is at blast furnace, this locates 200 ℃ of left and right of normal working temperature, when furnace charge is abnormal, transient temperature can reach 700 ℃, work under bad environment, raw gas dust content is high, during equipment cloth, the furnace charge of each batch of blast furnace rushes at distributor chute from the difference of altitude of some meters of material flow gate processes, also to control accurately turning angle and the speed of rotation of chute simultaneously, reliability to equipment, stability requirement is high, normal circumstances is generation furnace life.
The structure of distributor can be CN102363823A referring to application publication number at present, patent name is fork-arm type non-bell blast furnace distributing device, with Granted publication number be CN202099298U, patent name is the formerly patent of blast furnace bellless furnace top distributing gear, and the blast-furnace equipment of the making of Luxembourg Bao Er water (PW) company.Wherein the position of chute is all to control by its α angle with respect to distributor axis and β angle, the axis that wherein α angle is chute and the angle between distributor axis, in order to reach the uniform object of cloth, in cloth process, chute need to carry out the motion of both direction, a kind of motion is the swing that changes the angle between itself and distributor axis, object is the α angle that changes chute, another is the circumferential motion that drives chute to produce around distributor axis by drive unit, and object is to change the β angle of chute.The bell-less top equipment distributor of import PW company adopts planet differential structure, and equipment adopts closed circuit water-cooled, nitrogen-sealed, long, reliable in action of life-span, but complex structure, maintenance cost are high, and production cost is high.
Domestic furnace top equipment generally adopts open circuit water-cooled, nitrogen auxiliary seal, structure adopts connecting rod form or hydro-cylinder form, device structure is simple, the principle that its chute changes angle is to move up and down and drive chute crank to realize by the towing loop of lower rotating bearing is installed, or realizes by slide crank flute profile formula.Wherein the lower transmission mechanism in distributor α angle lapping actuation mechanism is: a kind of is to adopt towing loop to move up and down to drive chute crank to realize the variation at α angle in cloth process, and another kind is by driving slide crank flute profile formula to realize the variation at α angle in cloth process.These two kinds of lower transmission mechanism towing loops all can be born side force, general way controls for increasing track and roller the displacement that towing loop is produced by side force, in actual use procedure, α angle changes very little, frequency is high, and track and roller concentrated wear cause cloth precision to reduce, affect the normal use of equipment, because structure exists defect (towing loop is subject to side force), cause equipment precision poor, the life-span is short, cannot compete with overseas equipment.
