Abstract
The utility model discloses Sealing of Furnace Condenser Rotors structure, including power transmission shaft, lower end cap, bearing block, bearing, power transmission shaft is fixed with gland after sequentially passing through lower end cap and water jacket, bearing is arranged between bearing block and power transmission shaft, being provided with labyrinth seal in lower end cap, be provided with packing_seal between bottom end cover and labyrinth seal, labyrinth seal is fixed with power transmission shaft by securing member.This utility model novel structure, reasonable in design, by rotor lower bearing is moved to condenser in condenser, and the double-layer seal arranged seals and multilamellar packing_seal, the service life making rotor is greatly improved, more than 20 days are extended to, it might even be possible to continuous operation time reaches two months so that the cleaning period of blast furnace is extended by original about 10 days, not only reduce the labor intensity of workman, also a saving cost.
Description
Technical field
This utility model relates to a kind of sealing structure, is specifically related to a kind of Sealing of Furnace Condenser Rotors structure.
Background technology
Condenser rotor is the equipment that ISP in China zinc is the most important but also special, the most in various degree
Govern the production of blast furnace, strengthen owing to entering the furnace gas amount of blast furnace, condenser rotor thermic load increases, rotor
Working environment is very poor, and fault is many so that rotor is the lowest for service life, directly affects the cleaning period of blast furnace, limits
The production of blast furnace, existing condenser rotor lower bearing is in the high-temperature furnace gas of condenser, and bearing top and cylindrical are by water
Cold type bearing block water flowing cools down, and the movable sealing of bearing lower surface is the labyrinth seal of monolayer, and high-temperature furnace gas is easy to alter along axle
Entering in bearing, additionally, high temperature is conducted to lubricant and bearing by the bearing (ball) cover of contact furnace gas, and lubricant easily lost efficacy.Make
By proof, after rotor operating 10d, the lubricant of bearing space is all dried powdered or block, blocks bearing
Roller, lubricant failure causes rolling bearing to damage.Now, condenser rotor need to be hung out from condenser carry out disintegrate dimension
Repair, check that bearing adds the labor intensity of cost and workman.
Utility model content
For problems of the prior art, the purpose of this utility model is that design provides a kind of condenser rotor close
Seal structure.
Described Sealing of Furnace Condenser Rotors structure, including power transmission shaft, lower end cap, bearing block, bearing, described power transmission shaft depends on
Secondary fix with gland after lower end cap and water jacket, described water jacket arranges outlet, it is characterised in that described bearing is arranged
Between bearing block and power transmission shaft, described lower end cap is provided with labyrinth seal, between described lower end cap and labyrinth seal
Being provided with packing_seal, described labyrinth seal is fixed with power transmission shaft by securing member.
Described Sealing of Furnace Condenser Rotors structure, it is characterised in that described labyrinth seal is that double-layer seal seals, outside being divided into
Layer labyrinth seal and internal layer labyrinth seal.
Described Sealing of Furnace Condenser Rotors structure, it is characterised in that described packing_seal is multilamellar packing_seal.
Described Sealing of Furnace Condenser Rotors structure, it is characterised in that described securing member is round nut.
This utility model novel structure, reasonable in design, by rotor lower bearing is moved to condenser in condenser,
And the double-layer seal arranged seals and multilamellar packing_seal, make be greatly improved the service life of rotor, by original
Within about 10 days, extend to more than 20 days, it might even be possible to continuous operation time reaches two months so that the cleaning period of blast furnace obtains
To extend, not only reduce the labor intensity of workman, also a saving cost.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation；
In figure: 1-power transmission shaft, 2-lower end cap, 3-bearing block, 4-bearing, 5-water jacket, 6-gland, 7-labyrinth seal, 8-
Packing_seal, 9-round nut, 10-water jacket packing, 11-outlet.
Detailed description of the invention
This utility model is further illustrated below in conjunction with Figure of description.
As it is shown in figure 1, this utility model Sealing of Furnace Condenser Rotors structure, including power transmission shaft 1, lower end cap 2, bearing block 3,
Bearing 4, power transmission shaft 1 is fixed with gland 6 after sequentially passing through lower end cap 2 and water jacket 5, water jacket 5 is arranged outlet 11, bearing 4
It is arranged between bearing block 3 and power transmission shaft 1, lower end cap 2 is provided with inside and outside two-layer labyrinth seal 7, lower end cap 2 and labyrinth
Sealing and be provided with multilamellar packing_seal 8 between 7, labyrinth seal 7 is fixed with power transmission shaft 1 by securing member round nut 9, power transmission shaft 1
The position of corresponding water jacket 5 is provided with water jacket packing 10.
This utility model condenser rotor bearing seal is by having been moved to condenser by rotor lower bearing 4 in condenser
Outward, fundamentally solving bearing 4 and be chronically in the condenser of high temperature, lower bearing movable sealing is close from original monolayer labyrinth
Envelope is transformed into the high temperature resistant packing_seal of multilamellar and adds double-layer labyrinth sealing 7 and the structure of Double layer packing sealing 8, first packing_seal
High temperature resistant packing, water jacket 5 high-temperature furnace gas below is used to be isolated, it is difficult to enter the water jacket 5 sky above and between bearing block
Between, second labyrinth seal outer layer labyrinth stops furnace gas to scurry into bearing body further, and internal layer labyrinth seal stops the profit of bearing
Lubrication prescription is revealed, the lubricant of the 3rd road packing_seal main seal bearing body, and three seals interacts and stopped profit completely
Leakage and the furnace gas of lubrication prescription scurry into bearing, it is ensured that preferably sealing effectiveness.
