The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
It should be noted that, in the situation that not conflicting, embodiment and the feature in embodiment in the present invention can combine mutually.
Below with reference to accompanying drawing, embodiments of the invention are done to concrete explaination.
A kind of electromagnetic type oil filter of embodiments of the invention as shown in Figures 1 and 2, comprises housing 1, filter screen 4, coil 2 and power supply.
Coil 2 is connected with power supply, and coil 2 scrolls are set around the periphery of housing 1.One end of housing 1 is provided with oil-out 3, and the other end of housing 1 is provided with inlet port 6.Filter screen 4 be shaped as cylindrical shape.Filter screen 4 is located in housing 1.The center line of coil 2 is parallel with the center line of filter screen 4.The oil-out 3 of housing 1 is positioned at the inner side of filter screen 4, and the inlet port 6 of housing 1 is positioned at the outside of filter screen 4.
Embodiments of the invention flow to contrary settings by iron filings being adsorbed to direction and fluid, and it is identical that the iron filings that solved absorption and fluid flow to, the problem easily again being swept away, raising oil cleanliness, extension device service life.
As shown in fig. 1, in an embodiment of the present invention, on housing 1, be furnished with inlet port 6 and oil-out 3, on the top of housing 1, be wound with coil 2.On the central axis of oil-out 3, be furnished with filter screen 4, sieve plate 7 and flow-stopping plate 8, it is pressed on housing 1 by base plate 10 by spring 14.On base plate 10, be furnished with annular magnetic steel 13.Base plate 10 is fixing with housing 1 by packing ring 11 and bolt 12, between have 9 sealings of O shape circle.
And as shown in Figures 2 and 3, on the top of inlet port 6, being furnished with cover plate 5, the two connects by being arranged in first hinge 16 of cover plate 5 one end.The other end of cover plate 5 has a T-slot.There is cushion pad 15 position of the corresponding inlet port 6 of cover plate 5.At the other end of inlet port 6, there is a perforation circular hole, wherein through gangbar 18.One end of gangbar 18 embeds the T-slot of cover plate 5 by the second hinge 20, can in groove, slide.The other end of gangbar 18 is through sieve plate 7 and flow-stopping plate 8, fixing with position-limit mechanism 19.Sieve plate 7 and flow-stopping plate 8 are horizontal by same angle of inclination.The other end in the hole that on sieve plate 7, corresponding gangbar 18 is passed, is furnished with the lead 17 of vertical direction.
Embodiments of the invention are in working order time, the battery that optimization power supply is bull-dozer.Because the voltage of soil-shifting ship battery is lower, from battery power taking, need to improve voltage through boost module, and by current limliting insurance circuit, the electric current in coil 2 is limited to adjustment, make coil 2 reach suitable magnetic field intensity.As shown in Figure 4, coil 2 power taking from bull-dozer battery, is connected with coil with current limliting insurance module by boost module.
As shown in Figure 5, after coil 2 energisings on housing 1 top, produce magnetic field, housing 1 plays the effect of iron core and has strengthened magnetic field.Mix and have the fluid of iron filings from inlet port 6 enters, the cover plate 5 on inlet port 6 tops is backed down.Fluid, in the process of moving upward, is mixed in iron filings wherein, is attracted to housing 1 inwall under magnetic fields, containing the fluid of iron filings, by filter screen 4, from oil-out 3, does not discharge.When the cover plate 5 on inlet port 6 tops upwards lifts, by gangbar 18, drive flow-stopping plate 8 to move upward and be attached on sieve plate 7, block the through hole on sieve plate 7.Now the dirty storehouse of receiving of bottom is sealed, and guarantees that the iron filings of receiving in dirty storehouse can not sucked out again.
As shown in Figure 6, when off working state, no longer oil-feed of inlet port 6, the cover plate 5 on top also recovers horizontal level under Action of Gravity Field, by gangbar 18, drives flow-stopping plates 8 to fall, and exposes the through hole on sieve plate 7, receives dirty storehouse to open.Meanwhile, the disconnected magnetic field diminishes of coil 2, the iron filings of housing 1 inwall absorption fall under Action of Gravity Field.Due to sieve plate 7 inclination certain angles, iron filings are easy to drop into the hole on sieve plate 7.Also be furnished with an annular magnetic steel 13 receiving bottom, dirty storehouse, can adsorb to enter and receive the iron filings in dirty storehouse.The material of flow-stopping plate 8 is preferably plastics, can not held by annular magnetic steel 13.
During cleaning, only need unclamp the bolt 12 on base plate 10, take off base plate 10 and just can clear up the iron filings that are adsorbed on magnet steel.Owing to receiving, dirty storage capacity is larger, so do not need frequent maintenance, maintenance period is long.
In embodiments of the invention, also comprise a kind of bull-dozer, be provided with electromagnetic type oil filter described above.Because above-mentioned electromagnetic type oil filter has above-mentioned technique effect, therefore, the bull-dozer that is provided with this electromagnetic type oil filter also should possess corresponding technique effect, and its specific implementation process is similar to the above embodiments, does not hereby repeat.
Above specific embodiments of the invention be have been described in detail, but it is just as example, the present invention is not restricted to specific embodiment described above.To those skilled in the art, any equivalent modifications that the present invention is carried out and alternative also all among category of the present invention.Therefore, equalization conversion and the modification done without departing from the spirit and scope of the invention, all should contain within the scope of the invention.
