Abstract
The invention discloses a high-efficiency combined oil filter. An inner barrel is arranged in a shell of the oil filter; a space between the inner barrel and the shell is divided into a plurality of closed magnetic separation chambers by a plurality of permanent magnets; each magnetic separation chamber is provided with an inlet and an outlet; the inlet and the outlet are formed at opposite positions in each magnetic separation chamber respectively, namely the inlet end and the outlet are oppositely arranged in a manner of 180 degrees; all the permanent magnets are axially magnetized along the filter, and the south magnetic line and the north magnetic line are consistent; an oil path channel is arranged between the bottom of the inner barrel and the bottommost magnetic separation chamber; and a filter net is arranged in the inner barrel. Lubricating oil enters the magnetic separation chambers, and the permanent magnets adsorb metal particles in the lubricating oil; the lubricating oil is filtered through the stainless steel filter net, and the filtering effect is good; furthermore, the permanent magnets, the filter net, the inner barrel and the like can be independently cleaned; and the high-efficiency combined oil filter is convenient to assemble and disassemble and easy to clean.
Description
Technical field
The present invention relates to filter, particularly a kind of efficient combined-type magnetic oil filter.
Background technique
Large-scale running device as the friction pair of big-and-middle-sized piston compressor etc. be sliding bearing, easily wearing and tearing in operation process, the trickle metal granule of wearing and tearing is brought into lubricating oil system by lubricating oil, and then bring into again between friction pair, cause friction pair accelerated wear test, the running precision of fast reducing friction pair, directly affects working life of friction pair, forms vicious circle.Therefore, the turbidity test of lubricating oil system be lubricating oil filter filtration to improve service life of equipment significant.Most of compressor adopts net type filter, and minority compressor is set up magnetic filter in net type filter.The poor filtration effect of traditional net type filter, especially poorer to the filtering effect of trickle metal granule.The magnet of magnetic filter generally adopts monolithic construction, and lubricant oil is few with the area that magnet magnetic contacts compared with strong position, and the time of contact is short, and the area that magnetic contacts with lubricant oil compared with weak position is on the contrary large, poor to the adsorption effect of metal granule.Simultaneously, some filter screen and magnetic filter are integrated, and magnet is built-in structure, cleaning up inconvenience, in addition, this filter is due to the effect of magnetic, and metal granule is adsorbed on filter screen, and filter screen easily stops up, increase the resistance of lubricating oil system, reduce lubrication effect, and increased the number of times of wash oil filter, indirect loss is also larger.
Summary of the invention
In order to overcome the deficiency in background technique, the invention provides a kind of Combined type magnetic oil strainer, can ensure good filtering effect, magnet and filter screen can be separated to cleaning again, cleaning up is also very convenient.
For achieving the above object, the technical solution used in the present invention: a kind of efficient combined-type magnetic oil filter, comprise end cap, filler opening and oil outlet, in its housing, be provided with inner core, between described inner core and housing, be separated into multiple Magnetic Isolation chambers of connecting by polylith permanent magnet, between adjacent Magnetic Isolation chamber, passing hole channel is communicated with; All permanent magnets are all along the magnetization of filter entirety axis, and south, the north magnetic line of force are consistent; Inner core bottom with below Magnetic Isolation chamber between there is asphalt channel, in inner core, be provided with filter screen.
As preferably, described duct is the vertical slot being arranged in inner walls, vertical slot between each Magnetic Isolation chamber and a upper Magnetic Isolation chamber is oil-feed tank, and vertical slot between next Magnetic Isolation chamber is for going out oil groove, oil-feed tank with go out oil groove and be on the inwall that 180 degree are oppositely arranged on housing.
As preferably, described duct is the oil through on permanent magnet board, oil through side is provided with the oily dividing plate of gear, oil through between each Magnetic Isolation chamber and a upper Magnetic Isolation chamber is oil inlet hole, and the oil through between next Magnetic Isolation chamber is oil outlet, oil inlet hole and oil outlet lay respectively at the both sides of the oily dividing plate of gear.
As preferably, the upper and lower surface of described permanent magnet is recessed, intermediate thin, and cylindrical is thick, two adjacent annular permanent magnnets composition V-type groove Magnetic Isolation chambers.
As preferably, described inner core, housing and setting sleeve all adopt non-magnet material to be made.
Beneficial effect of the present invention:
(1) the lubricant oil Magnetic Isolation chamber of multiple series connection of flowing through, the metal granule time in separation chamber's internal permanent magnet adsorpting lubrication oil is long, and the separation chamber that lubricant oil is flowed through is strong magnetic line of force district, and filtering effect is better.
(2) upper and lower surface is the permanent magnet intermediate thin of scrobicular ring shape, and cylindrical is thick, biconcave permanent magnet composition V-type groove Magnetic Isolation chamber, and the cylindrical position of separation chamber is stronger near V-type groove place magnetic.When lubricant oil enters from a upper oilhole, while flowing along V-type groove Magnetic Isolation chamber, do tangential motion, will produce a kind of effect of centrifugal force.Because the proportion of metal granule is larger, under the effect of centrifugal force, metal granule will be thrown toward V-type rooved face, just in time be adsorbed by strong magnetic force, realize centrifugation simultaneously and separate with magnetic absorption, and separating effect is better.
(3) lubricant oil is after permanent magnet adsorbing filters, then filters through stainless steel filter screen, increases filter separating effect.
(4) Magnetic filtration device cavity is large, is difficult to stop up.Meanwhile, metal granule is first filtered by permanent magnet adsorbing, and stainless steel filter screen is also difficult to stop up, and the resistance of whole filter is little, and life cycle is long.
(5) point opening or cleaning such as permanent magnet, filter screen, inner core can be washed, easy accessibility, easily cleans.
