Abstract

The utility model discloses a magnetic absorption type oil filter, belongs to the technical field of internal combustion engines and automobile accessories, and aims to solve the problems of the prior oil filter, for example, in order to maintain normal working pressure of an oil passage, the filter openings can not be too fine, thereby causing the problems that the filtration efficiency is reduced; the filer openings are prone to be blocked by filtered impurity, and the service life is short. In order to solve the above problems, the technical scheme and the characteristics of the magnetic adsorption type oil filter are as follows: since the majority of the impurities in the oil are iron chips produced by wear and abrasion, without changing the basic structure of the prior oil filter, permanent magnets with matched shapes are additionally arranged in the spaces outside the upper and the lower covers and inside the shell, as well as the inner cavity of the central tube, and the iron chips are attracted to the magnets via the magnetic field of the magnets, thereby increasing the filtration efficiency and prolonging the service life of the oil filter. The magnetic absorption type oil filter is applied to the internal combustion engine and the vehicle filter, particularly the oil filter.

Description

The magnetic adsorption type oil filter

One, technical field:

A kind of magnetic adsorption type oil filter, the technical field of genus internal combustion engine and auto parts machinery.

Two, background technology:

Present oil filter generally is made up of housing, seal closure, rib-loop lid, filter core assembly, spring, sealing ring etc.Operation principle is that filter core is serially connected on the machine oil pipeline of engine, under certain pressure, machine oil enters from the fuel feed hole of rib-loop lid, after the filter opening of process filter core filters, the lid centre bore is gone out from the central tube to the rib-loop, enters each parts of engine again and is lubricated.Filter opening with volume greater than oneself impurity filter down, and stick to oneself the outside, and volume gets on less than the lubricant passage way that the impurity of filter opening still enters engine.For the normal pressure of oil circuit, filter opening again can not be meticulous, exists the contradiction of efficient and resistance.The machinery industry is to the standard (JB5088) of oil filter regulation: original filter efficiency greater than 60%, original resistance is less than 0.025MPa.Therefore, the weak point of conventional cleaner is: can not filter the impurity of lower volume less than filter opening, filter opening is easy to stop up, makes whole cleaner to scrap and need often change, and service life is very short.For solving above deficiency, the utility model is proposed.

Three, summary of the invention:

Content of the present invention technical problem to be solved is: design a kind of device, impurity less than filter opening can be stayed and with other by the impurity under filtering, do not adhere to or stick on the filter opening less, thereby improve filter efficiency and cleaner service life, do not influence the normal pressure of oil circuit again.The technical scheme that solves is: (impurity on the engine oil passage, major part are the iron end ashes that component wears such as high engine speeds running middle gear, bearing get off, and utilize these impurity to have ferromagnetic property, load onto permanent magnet at corresponding site and adsorb.) a kind of magnetic adsorption type oil filter, form by oil outlet, exterior seal ring, seal closure, rib-loop lid, fuel feed hole, inner seal ring, central tube, filter paper, housing, filter core lower cover, spring, filter core end cap, it is characterized in that the outside at filter core lower cover and filter core end cap, with the structure of magnetic or viscose glue, draw-in groove annular lower magnet is housed respectively or annular goes up magnet, with the fixing structure of magnetic bar magnet is housed in the inboard of housing, or in the inner chambers of central tube, adds bar magnet with magnetic or viscose glue, the fixing structure of draw-in groove; It is the toroidal that has centre bore that annular lower magnet and annular go up magnet, cross section is rectangular or square, triangle, polygon, circular, the cross section of bar magnet and bar magnet is triangle or polygon, circular, rectangular, foursquare elongate in shape, the shape of bar magnet can also be have oil-through hole and with central tube be concentrically ringed sheet.

After realizing this programme, can improve filter efficiency and the service life that prolongs cleaner, engine.

Four, description of drawings:

Accompanying drawing is a structural representation of the present utility model.1 is oil outlet, the 2nd among the figure, exterior seal ring, the 3rd, seal closure, the 4th, rib-loop lid, the 5th, fuel feed hole, the 6th, magnet on the annular, the 7th, inner seal ring, the 8th, central tube, the 9th, filter paper, the 10th, bar magnet, the 11st, housing, the 12nd, filter core lower cover, the 13rd, annular lower magnet, the 14th, spring, the 15th, filter core end cap, the 16th, bar magnet.

Five, the specific embodiment:

According to each cavity size of the inboard of the filter core lower cover 12 in the conventional cleaner, filter core end cap 15 outsides and housing 11 inboards, central tube 8, the customization annular goes up magnet 6, annular lower magnet 13, bar magnet 16, bar magnet 10 and does accessory.The external diameter of magnet 6 and annular lower magnet 13 should be less than filter core lower cover 12 on the annular, and has corresponding centre bore, and its thickness is big as far as possible under space permission situation, so that the enhancing magnetic attraction.Notice that annular goes up magnet 6 and leaves the oil circuit cavity should for fuel feed hole 5, but the little perforate grooving in space solves.Structure is magnet to be inhaled get final product in the outside of filter core lower cover 12 or filter core end cap 15, if the plastic cover plate of non iron, available viscose glue or draw-in groove mode are fixed, and also can not fix, with the structure of corresponding free displacement, so that the expansion adsorption range.

Be contained in the bar shaped bar magnet 10 of housing 11 inboards, length is less than housing 11, and shape is that cross section is triangle or polygon, circular, rectangular, foursquare elongate in shape, and quantity is advisable evenly to load onto 2～6 in housing one circle, directly suction gets final product in the inboard of housing 11, also allows relative free displacement.

If improve filter efficiency again, can in the inner chambers of central tube 8, install bar magnet 16 additional, its length should be less than the height of central tube 8, shape is that cross section is triangle or polygon, circular, rectangular, foursquare elongate in shape, can also be have oil-through hole and with central tube 8 are concentrically ringed sheets, vertical with central tube 8 or laterally all can, length should conform in the internal diameter of central tube and holds or be fixed on the inboard of central tube 8 in the time of laterally; Vertical inboard center of inhaling at filter core lower cover 12, the filter core lower cover 12 of non iron can be fixed with viscose glue or draw-in groove, also can not fix, and allows free displacement, enlarges the dust suction scope; If the sheet concentric with central tube then filled in central tube and got final product, can also play support ring.

For gathering the grey impurity in iron end more, can also on each magnet, have slotted eye.Before cleaner seals, above-mentioned parts are assembled to seal by corresponding site together and get final product.

Also can be used in the cleaner of diesel oil, air and water.
