Abstract
The utility model relates to a blast furnace external driving distributing device, and a seal. A rotary and swing driving mechanism of a distributing chute is arranged on the exterior of the blast furnace, and a rotary body and a contiguous static position use the combined mechanical seal.
Description
Luxembourg Er Wosi company has proposed no bell furnace roof scheme before 30 years, is called PW type furnace roof, and the principal feature of this furnace roof is to adopt sealing of valve formula and chute cloth, and it has greatly improved than the clock-type furnace roof in past.But, thereby also there is following shortcoming because chute is rotated PW type furnace roof and the driving mechanism of swing is arranged in the stove:
For guaranteeing the works better of drive disk assembly in the chute driving box, must adopt sealing gland, this has just increased the running cost and the investment of equipment widely.The chute driving mechanism is arranged on airtight box inside, can't overhaul at ordinary times, lubricated difficulty; The chute driving mechanism all is arranged in the stove, thereby security is relatively poor, in case sealing gland and water-cooling system break down, all mechanism will be subjected to the catastrophic explosion of furnace high-temperature; Because the drive system of chute rotation and swing is all in airtight box, thereby the orientation of chute and inclination angle can't directly measure and control, and can only measure indirectly and control.
For overcoming above-mentioned shortcoming, whole driving mechanisms of having invented a kind of novel " blast furnace surface-driven distributing device and tightness system thereof " its principal character and be chute rotation and swing are arranged on outside the stove, distributor rotation position and adjacent static position be sealed into compound seal.
This new device overcomes the above-mentioned shortcoming of PW type furnace roof fully, it is without nitrogen or purified gas, because driving mechanism and bearing all are located at outside the stove, the equipment operating safety, the mensuration at chute inclination angle and Controlling System are simplified greatly and are reliable, and bring great convenience for the lubricated and maintenance of chute drive system.

The flange connection of the lower seal valve of last stationary ring group (9) and loading device, following stationary ring group (19) and roof support ring flange connection.
Distributor chute (17) is by chute axle (20) supporting and adopt spline to link, chute axle (20) is located at axial and radial support by the bearing I I (14) on the rotator (16), between bearing I I (14) and the chute (17), be provided with packing seal (15), the transmission arm of force (21) is equipped with in chute axle (20) outer end, on the transmission arm of force (21) the other end roller (22) is housed.
During rotator (16) rotation, roller (22) is gone up at circular orbit (23) and is rolled, and the height of roller (22) is by circular orbit (23) control, and control circular orbit (23) height just can make chute axle (20) rotation and chute (17) swing.
A plurality of nuts and pinion(gear) (4) are housed between wheel casing chassis (24) and wheel casing cover plate (11), and locate at axial and radial support by bearing I II (3); Bull gear (2) is equipped with in nut and pinion(gear) (4) outside, and bull gear (2) is located at axial and radial support by sliding surface bearing (1); The rotation of bull gear (2) is driven by pinion(gear) II (13) by motor and speed reduction unit II (12).Screw mandrel (5) is housed in nut and the pinion(gear) (4), and screw mandrel (5) lower end and circular orbit (23) connection connect.
When motor and speed reduction unit I (7) running, drive rotator (16) rotation by pinion(gear) I (6), also make the distributor chute (17) that is bearing on the rotator (16) around the rotation of blast furnace center simultaneously.
When motor and speed reduction unit II (12) running, drive bull gear (2) rotation by pinion(gear) II (13), bull gear (2) drives to be gone up a plurality of nuts and pinion(gear) (4) its garden week and rotates and make screw mandrel (5) and circular orbit (23) lifting, make roller (22) upper and lower displacement during circular orbit (23) lifting again, then by the transmission arm of force (21), drive chute axle (20) rotation, realize control distributor chute (16) inclination angle.
Composite seal device can be illustrated by the accompanying drawing 2 of one of embodiment, this cover tightness system is installed between distributor rotator and the adjacent static position, pairing flange is carried out the static seal connection on rotating ring chamber (25) and the rotator, overlaps the flange at flange (31) the static position adjacent with distributor in the water-cooled of stationary ring part and carries out the static seal connection.The sealing that distributor rotation position is adjacent between the static position is realized by composite seal device of the present invention.
Composite seal device of the present invention is based on mechanical seal, mechanical seal constitutes double seals by rotating ring (32) and stationary ring (38), the elastic force of little spring (26) and inner corrugated pipe (28) is adjacent to the Double End on rotating ring (32) and the stationary ring (38), and inner corrugated pipe (28) can compensate the wearing and tearing of dynamic and static ring.Inner corrugated pipe (28) little spring (26) is arranged on inside, rotating ring chamber (25), and stationary ring (38) is arranged in the annular space chamber that is made of stationary ring outer ring (34) and water jacket (31), and is sealed by O type circle (37); Little spring (26) by axle (27) in radial location.
In rotating ring chamber (25) and water-cooled, overlap between (31), be provided with a ring-shaped air chamber (29), passage (36) in water-cooled the cover (31) charges into clean gas in ring-shaped air chamber (29), clean gas enters blast furnace from the gap that ring-shaped air chamber (29) overlaps between (31) in restrictor ring (30) and water-cooled.Air pressure in the ring-shaped air chamber (29) is higher than stock gas pressure, and blast furnace gas and mechanical sealing surface are cut off.
