Description
Technical field
The present invention relates to a kind of experimental branch line equipment ancillary equipment, scraper plate in specifically a kind of polyester device batch condensation polymerization reactor
Condenser internal bearings dust-proof lubricating device.
Background technique
In smelt direct spinning terylene long filament production process, general polyester device using Zhong Fang institute five autoclaves process, two
Three polycondensation vessels of esterifying kettle: the first reaction kettle of the esterification, the second reaction kettle of the esterification, the first prepolymerization reaction kettle, the second precondensation are anti-
Answer kettle, final polycondensation reaction kettle.One of five kettle polyester device polycondensation reaction condition of Zhong Fang institute: polycondensation reaction vacuum system, vacuum system
Capital equipment of uniting is scraper condenser.During the vacuum suction of reactor, the oligomer in reactor can be extracted out by vacuum,
Aggregation is agglomerated along the duct wall in vacuum system, thus causes vacuum system line clogging.It is oligomeric in reactor to prevent
Object is gathered in the surface of vacuum system pipeline, so exporting setting scraper condenser device in reactor vacuum gas-phase pipe.Scraper plate
Condenser mainly traps oligomer, and will hang over wall by rotating scraper plate and be gathered in neat at condenser inlet
Polymers block scrapes.Oligomer flows into ethylene glycol liquid seal can together with spray and the ethylene glycol of condensation, passes through hanging basket and filter
Oligomer is removed, and is periodically discharged, so that vacuum system is dredged, the burden of poly- vacuum system in mitigation.
Be made of inside scraper condenser scraper and knife rest, installation on the rotary shaft, by internal bearings by long axle suspension
Extension is fixed in cylinder, and cylinder inner bearing is designed as virgin ethylene glycol and rinses lubrication.Motor reducer drives long axis rotation, makes scraper will
The oligomer for condensing upon barrel surface scrapes, and flows out with spray liquid, extremely along scraper condenser bottom barometric pipe discharge of pipes
In lower part equipment liquid seal can, the blocking of vacuum gas-phase pipeline is avoided.
However scraper condenser inner pedestal designs upper existing defects, the forward and backward gland gap of bearing block is larger, and sets gland
There are two drainage holes at middle part, and the ethylene glycol for rinsing lubrication can be from gland gap and two drainage hole streams after entering bearing chamber
Out, sufficient lubrication can not be carried out to bearing, and gland gap is excessive, is that the oligomer extracted out in reactor enters in bearing chamber,
Bearing card resistance is caused to wear, or even damage.Therefore, our company technical staff invents a kind of dust-proof profit of scraper condenser internal bearings
Sliding device.
Summary of the invention
The purpose of this utility model is that making up the deficiencies in the prior art, a kind of scraper condenser inner shaft is provided
Dust-proof lubricating device is held, solves the problems, such as condenser bearing lubrication, wear damage, effectively can prevent oligomer from entering bearing chamber
It is interior, and guarantee condenser internal bearings sufficient lubrication.
In order to achieve the above objectives, a kind of scraper condenser internal bearings dust-proof lubricating device, it is characterised in that including axis, axis
Set, bearing, bearing block, gland, fixing bolt, outside framework oil seal, the axle sleeve cover on axis；The bearing holder (housing, cover) is in axle sleeve
On, it is fixed in bearing block；The outside framework oil seal is annulus with groove, is mounted on the annulus gland with fixed groove
It is interior, it is mounted with that the gland of outside framework oil seal is mounted on bearing block two sides using fixing bolt, outside framework oil seal is contacted with axle sleeve, for close
Gap between sealed cover and axle sleeve.
The outside framework oil seal, it is characterised in that using made of thermostable fluorine rubber material, device security is not influenced,
Sealing effect is good；The groove for being mounted on the outside framework oil seal side in gland is inside, for bearing pressure；The groove of the other side is to axis
Lateral direction installation is held, is in order to make to rinse the ethylene glycol lubricated under the effect of the pressure, along the outside framework oil seal reversely installed
Groove is gone out, and overflows the lubricating fluid after being pressurized along groove direction.
Utility model device outside framework oil seal forms seal chamber, so that the ethylene glycol for rinsing lubrication is sufficient filling with completely close
The envelope chamber of outside framework oil seal is overflowed from the outside framework oil seal groove reversely installed, and ethylene glycol sufficiently fills out in guarantee bearing block seal chamber
It fills and lubricates, prevent the oligomer extracted out by vacuum system and flue gas from entering in bearing card resistance is caused to wear, and will not be due to
Pressure is excessive to generate the damage for building the pressure and causing outside framework oil seal.
The progress effect of the utility model is:
1. ensure that bearing sufficient lubrication；
2. solving the problems, such as condenser bearing lubrication, wear damage, effectively it can prevent oligomer from entering in bearing chamber,
External impurities are avoided into card resistance is caused in figure bearing block, ensure that condenser operates normally.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of utility model device, and Fig. 2 is bearing block top view；Fig. 3 is gland top view；Figure
4 be the main view of gland.
Wherein: 1 is axle sleeve；2 be bearing block；3 be bearing；4 be gland；5 be fixing bolt 6 be axis；7 be outside framework oil seal；
8 be ethylene glycol pipeline.
Specific embodiment
The utility model is described in detail below with reference to embodiment.
A kind of scraper condenser internal bearings dust-proof lubricating device of the utility model, including axis (6), axle sleeve (1), bearing
(2), bearing block (3), gland (4), fixing bolt (5), outside framework oil seal (7), axle sleeve (1) cover on axis (6), and bearing (2) covers
On axle sleeve (1), it is fixed in bearing block (3)；The outside framework oil seal (7) is annulus with groove, is mounted on anchor
In the annulus gland (4) of slot, it is mounted with that the gland of outside framework oil seal is mounted on bearing block (3) two sides, skeleton using fixing bolt (5)
Oil sealing is contacted with axle sleeve, for the gap between sealing gland and axle sleeve.
The outside framework oil seal does not influence device security, sealing effect is good using made of thermostable fluorine rubber material；
The groove for being mounted on the outside framework oil seal side in gland is inside, for bearing pressure；The groove of the other side to bearing lateral direction,
It is to be gone out along the outside framework oil seal groove reversely installed in order to make to rinse the ethylene glycol lubricated under the effect of the pressure, make to be pressurized
Lubricating fluid afterwards is overflowed along groove direction.
Utility model device outside framework oil seal forms seal chamber, and ethylene glycol is entered closed by ethylene glycol pipeline (8)
Bearing block (3), after filling inside bearing block, under the effect of the pressure, a side seam that will be small to the anti-receiving pressure filled
The outflow of frame oil sealing groove, ensure that and sufficiently fill ethylene glycol in bearing block, prevent the oligomer and flue gas extracted out by vacuum system
It causes card resistance to wear in into bearing, and the damage for building the pressure and causing outside framework oil seal will not be generated since pressure is excessive.
