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；Consider core 9 by multiple strainers 10, permanent magnet strainer 11, upper ring 12, multiple intermediate rings 13,
Lower ring 14 forms, and respectively installs a piece of strainer 10, strainer 10 between upper ring 12 and first intermediate ring 13, between each intermediate ring 13
Mesh number from top to bottom is gradually increased, and permanent magnet strainer 11, permanent magnetism are installed between most next intermediate ring 13 and lower ring 14
Iron strainer 11 is at square grid shape or the other shapes such as strip-type grille shape or scroll, upper ring 12, multiple intermediate rings 13, lower ring
14 have hole, are superimposed and install strainer 10 and permanent magnet strainer 11 for upper ring 12, multiple intermediate rings 13, about 14 lower ring, use spiral shell
Bolt pass through upper ring 12, multiple intermediate rings 13, lower ring 14 hole and being secured with nuts to be formed and consider core 9；The large-scale generator rotor
The oil strain method of bearing oil is: bearing oil is fallen into lower fuel tank from top tank 1 by lower oil pipe 3, then has oil pump 5 will
The bearing oil with pollutant in lower fuel tank is pumped into top tank 1, forms a circulation, in this cyclic process,
Bearing oil with pollutant passes through oil-filtering apparatus 4 per secondary, and 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 permanent magnet strainer 11 every time,
The magnetic field suction iron powder of permanent magnet strainer 11 is simultaneously adhered on the outer wall of permanent magnet strainer 11, and the work of filtering iron powder is played
With, 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 primary by filtering,
Through being filtered for multiple times and cleaning replacement consider core 9 strainer 10 and permanent magnet strainer 11, so that it may bearing oil is filtered quickly
Completely reach requirement, finally remove and consider core 9, remaining equipment retains the cooling-cycle apparatus as bearing oil
Come.

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 permanent magnet strainer 11 every time, forever
The magnetic field suction iron powder of magnet strainer 11 is simultaneously adhered on the outer wall of permanent magnet strainer 11, plays the role of filtering iron powder,
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 primary by filtering, pass through
It is filtered for multiple times and the strainer 10 and permanent magnet strainer 11 of core 9 is considered in cleaning replacement, so that it may quickly filter bearing oil clean
Reach requirement, finally remove and consider core 9, remaining equipment remains the cooling-cycle apparatus as bearing oil；It needs
Illustrate: it is multiple that oil-filtering apparatus 4 can pass in and out installation at oil in gen-set pipeline；Permanent magnet strainer 11 is installed on considering core 9
One or more.
