Description
Technical field
Greasy dirt is removed present invention is mainly used for the rotor bearing lubricating oil of large-scale generator to use.
Background technique
Cleannes requirement into the lubricating oil of the rotor bearing of large-scale generator is very high, and lubricating oil needs defeated by pipeline
It is sent in the oil storage room of rotor bearing, the cleannes of the inner wall of these conveyance conduits also require very high, otherwise can pollute bearing
Lubricating oil all can not to pipeline completely to the cleaning of the cutting of interface, polishing, welding and inner wall of the pipe when installing oil pipeline
Bearing oil is polluted, the pollutions such as iron filings, the iron powder of inner wall of the pipe are especially retained in cutting, polishing of the pipeline to interface
Object is difficult processing completely, and conventional oil strain method is that strainer is installed on pipeline road, carries out multiple circulating filtration, this method
The filter screen of different meshes need to be repeatedly replaced, consuming time is long, and the oil strain period is long, and work consuming is time-consuming.
Summary of the invention
The present invention solves the above problem, it can greatly improve the oil strain period, saves time cost, it is mainly by oiling
Case 1, lower fuel tank 2, lower oil pipe 3, oil-filtering apparatus 4, oil pump 5, upper oil pipe 6 form；With lower oil pipe 3 between top tank 1 and lower fuel tank 2
It connects, lower oil pipe 3 is equipped with oil-filtering apparatus 4, the method for ring flange 7 bolt and nut and lower oil pipe 3 of the upper and lower side of oil-filtering apparatus 4
Blue disk connection, oil-filtering apparatus 4 are made of ring flange 7, tube wall 8, worry core 9, and the upper and lower side of tube wall 8 is fixed with ring flange 7, tube wall 8
It is equipped in the cavity surrounded and considers core 9；Core 9 is considered by multiple strainers 10, electromagnetic induction coil 11, upper ring 12, multiple intermediate rings
13, lower ring 14 forms, and respectively installs a piece of strainer 10 between upper ring 12 and first intermediate ring 13, between each intermediate ring 13, filters
The mesh number of net 10 from top to bottom is gradually increased, and installs electromagnetic induction coil between most next intermediate ring 13 and lower ring 14
11, electromagnetic induction coil 11 is connected at scroll, the positive and negative anodes of electromagnetic induction coil 11 and the positive and negative anodes for crossing wall attaching plug 15,
It crosses wall attaching plug 15 to be mounted on tube wall 8, upper ring 12, multiple intermediate rings 13, lower ring 14 have hole, by upper ring 12, Duo Gezhong
Between ring 13, about 14 lower ring be superimposed and install strainer 10 and electromagnetic induction coil 11, pass through upper ring 12, multiple intermediate rings with bolt
13, the hole of lower ring 14 and being secured with nuts, which to be formed, considers core 9；The oil strain method of the large-scale generator rotor bearing oil is:
Bearing oil fallen into lower fuel tank from top tank 1 by lower oil pipe 3, then have oil pump 5 by lower fuel tank with pollutant
Bearing oil is pumped into top tank 1, forms a circulation, in this cyclic process, the bearing oil with pollutant
Pass through oil-filtering apparatus 4 per secondary, the small strainer 10 of the mesh number of oil-filtering apparatus 4 filters the pollutant of bulky grain, the big strainer 10 of mesh number
The pollutant of filter small particles, when powdery iron powder pollutant passes through electromagnetic induction coil 11 every time, the electricity of electromagnetic induction coil 11
Magnetic field suction iron powder is simultaneously adhered on the outer wall of electromagnetic induction coil 11, plays the role of filtering iron powder, process every in this way
One cycle, the pollutants such as bulky grain, little particle and iron powder in bearing oil are just primary by filtering, by being filtered for multiple times and
The strainer 10 of cleaning replacement worry core 9, so that it may bearing oil filtering completely be reached into requirement quickly, finally remove and consider core
9, remaining equipment remains the cooling-cycle apparatus as bearing oil.

Specific embodiment
Referring to Fig. 1 to Fig. 5, bearing oil is fallen into lower fuel tank from top tank 1 by lower oil pipe 3, then have oil pump 5 will under
The bearing oil with pollutant in fuel tank is pumped into top tank 1, forms a circulation, in this cyclic process, band
There is the bearing oil of pollutant to pass through oil-filtering apparatus 4 per secondary, the small strainer 10 of the mesh number of oil-filtering apparatus 4 filters bulky grain
Pollutant, the pollutant of big 10 filter small particles of strainer of mesh number, when powdery iron powder pollutant passes through electromagnetic induction coil 11 every time,
The electromagnetic field of electromagnetic induction coil 11 attracts iron powder and is adhered on the outer wall of electromagnetic induction coil 11, plays filtering iron powder
Effect, every in this way to pass through one cycle, the pollutants such as bulky grain, little particle and iron powder in bearing oil are just by filtering one
It is secondary, by being filtered for multiple times and the strainer 10 of core 9 is considered in cleaning replacement, so that it may bearing oil filtering completely be reached use quickly
Core 9 is considered it is required that finally removing, remaining equipment remains the cooling-cycle apparatus as bearing oil；It needs to illustrate: oil strain
It is multiple that device 4 can pass in and out installation at oil in gen-set pipeline.
