Abstract
The utility model belongs to the mechanical device of the rotation material pot without material bell in a cluster pot type of the blast furnace. A swivel joint adopts a connection device of rigid fixing flanged type to generate radial bouncing and axial movement. Thus the moveable sealing ring and the core sealing surface of the swivel joint are ineffective in an early time, a large quantity of liquid is leaked, a material flow control valve can not be opened and a rotation material slot stops rotation. The utility model raises the swivel joint with 800 mm. A device used for engaging an outer crowned tooth in a moveable type and an involute internal tooth is additionally arranged. The outer portion of a swivel sleeve cylinder is additionally provided with a set of double-row tapered roller bearing. The positioning connection mode of a liquid transport pipeline is converted into a swivel connection mode. The utility model is convenient for installation and maintenance and the service life is improved by more than 6 times and the 100% running rate of the rotation material pot is realized. The iron yield of the blast furnace of Angang 11 model is increased by 270 t per day and the coke ratio is lowered by 18 kg/t. The economic benefit in each year is 14 million yuan.
Description
The utility model belongs to the mechanism that the blast furnace tandem tank type does not have bell rotation batch can.
As everyone knows, rotary joint is installed in the top that tandem tank type does not have bell rotation batch can, transmits hydraulic efficiency oil, lubricating oil and electric current by the revolution mode.For realizing the initial circumferentially uniform distribution of furnace charge, overcome particle segregation, the rotation batch can rotates with top materials flow control valve together at when filling with substance, and the rotary joint fuse also must can satisfy top materials flow control valve and open and close function along with synchronous rotation.But because the rotation batch can is bulky, rotary joint adopts and to rigidly fix the flanged type coupling unit, diameter run-out that the low rotation batch can that do not disappear produces in rotary course and the axial motion value that exceeds standard.Cause rotary joint rotary packing ring and rotary joint fuse trim premature failure, the hydraulic efficiency oil of 20MPa is leaked in a large number.Materials flow control valve in top can't open and close, and the rotation batch can is forced to stall, loses the adjustment means of the initial cloth of furnace roof.
The utility model is to improve at above-mentioned shortcoming, uses internal tooth engages and seals formula rotary joint device.
Accompanying drawing 1 is an internal tooth engages and seals formula rotary joint device synoptic diagram.［ 1 ］ is the rotary joint housing among the figure, ［ 2 ］ be anti-torsion bar, ［ 3 ］ be the rotary joint fuse, ［ 4 ］ be the revolution sleeve, ［ 5 ］ be the rotary joint base, ［ 6 ］ are movable outer barreled tooth flank, and hold for the double row tapered roller axis of a cylinder ［ 7 ］, ［ 8 ］ be the bearing fixing housing, ［ 9 ］ are liquid conducting pipes.
Main points of the present utility model are that swivel coupling housing ［ 1 ］ is fixed on the basis by anti-torsion bar ［ 2 ］, swivel coupling fuse ［ 3 ］ is connected on the revolution sleeve ［ 4 ］, swivel coupling is raised 800mm, swivel coupling base ［ 5 ］ connects with movable outer barreled tooth flank ［ 6 ］, movable outer barreled tooth flank is meshed with revolution sleeve ［ 4 ］ bottom involute internal tooth, consists of inner gear engagement sealed rotary joint device. Set up one group of double row tapered roller axis of a cylinder in revolution sleeve outside and hold ［ 7 ］, the double row tapered roller axis of a cylinder holds ［ 7 ］ and is contained in the bearing stationary housing ［ 8 ］, liquid delivery tube Road ［ 9 ］ is converted to the revolution connecting mode by the location connecting mode.
Use the utility model, when the rotation of rotation batch can, help improving transmitting torque, increase the allowable offset (angular variation can reach 6 °) of axis.Can offset well in rotary course that rotary joint fuse position produces radially, axial dipole field, it is concentric that rotary joint fuse and rotary joint housing are remained, so improved the reliability of equipment.Liquid conducting pipes is converted to the revolution connecting mode by the location connecting mode, guarantees to supply with top materials flow control valve hydraulic efficiency oil, has improved the maintenance condition of equipment.
The utility model was installed on No. 11 blast furnace tandem tank types of the Anshan iron and steel plant feeder apparatus on November 20th, 1991, compare with existing equipment, be convenient to installation and maintenance, improve the life-span more than 6 times, realize rotation batch can operation factor 100%, increase production 270t iron every day, reduce coke ratio 18kg/t, 1,400 ten thousand yuan of year wound economic benefits.
Claims (2)
1, a kind of rotary joint is installed in the top that tandem tank type does not have bell rotation batch can, rotary joint adopts and rigidly fixes the flanged type coupling unit, it is characterized in that said rotary joint housing is fixed on the basis by anti-torsion bar, the rotary joint fuse is connected on the revolution sleeve, rotary joint is raised 800mm, the rotary joint base connects with movable outer barreled tooth flank, and movable outer barreled tooth flank is meshed with revolution lower cartridge involute urve internal tooth, constitutes internal tooth engages and seals formula rotary joint device.
