Abstract
The invention provides an electromagnetic filter element filter capable of being automatically cleaned. The electromagnetic filter element filter capable of being automatically cleaned comprises a pressure detection device, an electromagnetic valve, an electromagnetic filter element, a filtering mechanism and an ultrasonic device. The electromagnetic filter element filter capable of being automatically cleaned is characterized in that the pressure detection device detects pressure of hydraulic oil; the electromagnetic valve controls an oil inlet of an oil filter to be opened and closed; the ultrasonic device is installed on the upper portion of the oil filter; in work, ultrasonic waves are given out to clean the filter element; impurities in filter holes are cleaned into a gap between a shell and the filter element; when the electromagnetic filter element is powered on, the filter element has magnetism, and when the electromagnetic filter element is powered off, the magnetism disappears; the filtering mechanism rotates after cleaning is completed, and oil containing lots of dirt is discharged out of the oil filter; and after oil discharge is completed, the filtering mechanism resets. The electromagnetic filter element filter capable of being automatically cleaned achieves the automatic cleaning function on the electromagnetic filter element, reduces resource waste and man hour waste caused by replacement of the filter element, effectively guarantees the quality of the hydraulic oil and powerfully guarantees stable work of a hydraulic system.
Description
Technical field
The present invention relates to a kind of oil filter that can be self-cleaning, a kind of electro permanent magnetic possessing automated cleaning filter element filters
Device.
Background technology
Hydraulic oil often contains granule foreign, the abrasion of Hydraulic Elements relative motion surface, guiding valve clamping stagnation, joint can be caused
Discharge orifice mouth blocks, and the system functional reliability of making is greatly lowered.The oil filter of certain precision is installed in systems, is to ensure that hydraulic pressure system
The necessary means of the normal work of system.At present, wide variety of is the oil filter of disposable element, oil filter work a period of time it
After, impurity will block filter opening, and effect of oil filter will be had a greatly reduced quality, for ensureing the quality of hydraulic oil, it has to change filter
Oil device.Man-hour can be taken when this oil filter is not only changed, also can cause the waste of resource, less economical；If changing not in time
Filter element, will produce inevitably infringement to whole hydraulic system.A kind of self-cleaning filter element can be completed for this reason, it may be necessary to design
Oil filter.
Summary of the invention
The invention provides a kind of can the filter of electro permanent magnetic filter element of automated cleaning, it achieve according to hydraulic oil
Quality carries out the function of automated cleaning filter element, meets the requirement that oil filter the most normally works, and possesses raising hydraulic system
Stability, the oil filter working life that improves, the feature of minimizing replacing oil filter number of times.
For solving the problems referred to above, the technical solution used in the present invention is: one can be carried out according to hydraulic oil quality automatically
The oil filter of cleaning filter element, it includes external pressure detection device, electromagnetic valve, electro permanent magnetic filter element, filter mechanism and ultrasound wave dress
Put.It is characterized in that the difference of pressure-detecting device detection oil filter oil-in and the oil pressure of oil-out, signal intensity sends micro-place to
Reason device, if it is determined that be cleaned filter element for needs, microprocessor sends instruction, electromagnetic valve work.
Described electromagnetic valve is arranged on oil filter oil-in, when hydraulic system normally works, is in normally open, works as electromagnetism
Valve receives the signal of telecommunication, electromagnetic valve work, and oil filter stops oil-feed, and supersonic generator works.
Described ultrasonic unit is arranged on oil filter top, during work, sends ultrasonic waves for cleaning filter element, miscellaneous by filter opening
Matter cleans in the space between shell and filter element.
Described electro permanent magnetic filter element is in the duty that is energized hydraulic system normally works when, makes filter element possess magnetic
Property, when ultrasonic unit works, electromagnetism filter element power-off, magnetic disappears.
Described filter mechanism, after cleaning completes, rotates, and the oil containing a large amount of dirts is discharged oil filter, and oil extraction is complete
Cheng Hou, filter mechanism resets.
The invention has the beneficial effects as follows: achieve the automatic cleaning function to electro permanent magnetic filter element, decrease replacing filter element band
The wasting of resources come and waste in man-hour, be effectively ensured the quality of hydraulic oil, it is effectively guaranteed that the steady operation of hydraulic system.

Detailed description of the invention
For the technical characterstic of this programme can be clearly described, below by a specific embodiment, and combine accompanying drawing, right
This programme is illustrated.
As shown in Figure 2, the present invention a kind of can be self-cleaning electro permanent magnetic oil filter, described pressure-detecting device detection oil filter
The oil pressure of oil-in and oil-out, and transfer data to microprocessor and process, when reaching limit value, microprocessor sends
Signal is to electromagnetic valve 9.
Described electromagnetic valve 9 is arranged on oil filter oil-in end, after receiving signal, normally open is switched to closed mode,
Now oil filter stops oil-feed.
Described ultrasonic unit 2 is arranged between shell and filter element, at oil filter oil-out end.Oil filter stops oil-feed
After, ultrasonic unit 2 works, and sends ultrasonic waves for cleaning filter element.
Described electro permanent magnetic filter element 4 is powder sintered filter element, and is wound with coil, during coil electricity, and whole filter element
Possesses magnetic.While ultrasonic unit works, stopping energising, filter element 4 loses magnetism.The electrode of electro permanent magnetic filter element 4 is in filter
Connect with external power source bottom oil device.
Described filter mechanism is made up of back-moving spring 10, runner 12, blade 11, electric magnet 8 part such as grade.Runner 12 is machined with
Through hole and blade 11, equipped with electric magnet 8 on blade, runner hole can communicate with oil leaking hole.When defecator does not works, now blade
11 are in home position, and runner hole is disconnected with oil leaking hole.When defecator works, electric magnet 8 is energized, and runner 12 rotates,
Runner hole is connected with oil leaking hole, and the hydraulic oil containing a large amount of dirts flows out.After cleaning, electric magnet power-off, runner 12 is at bullet
Under the effect of spring 10, set back.
After described filtering mechanism works completes, provide signal and fill 2 put stopping to microprocessor, microprocessor control ultrasound wave
Work, electromagnetism filter element 4 is energized work, and electromagnetic valve 9 is switched to normally opened by closed mode, and whole cleaning process completes.
