Abstract

The utility model relates to a filter element for compound rare earth foam metal machine oil regeneration, which mainly comprises a filter sleeve, a matrix drum and a core tube, wherein the filter sleeve on the outermost layer is made of a special material which is not dissolved in oil, has water absorption and filterability and is slightly influenced by temperature, and the special material can be a carbon fiber yardage roll or a non-woven yardage roll or a fiber paper roll; the matrix drum in the middle is manufactured into a hollow drum with certain thickness by metal foam made of rare earth mixed matrix metal; and the core tube in the center is a hollow tube which has certain strength and is bestrewed with through holes. The filter element for the compound rare earth foam metal machine oil regeneration aims to repair broken molecular chains or molecular chains being about to break in machine oil by utilizing rare earth elements so as to enable the machine oil to be restored into an original initial state to be put back for use, the effective service life of the machine oil in machines is prolonged to 10 times of the existing service life or above.

Description

Compound rare-earth foam metal oil renewal filter core

Technical field

The utility model is a kind of machine oil filter core, particularly a kind ofly can effectively repair the compound rare-earth foam metal oil renewal filter core that the machine oil macromolecular chain makes the long-acting maintenance initialization of machine oil state.

Background technology

The machine oil that uses in the various plant equipment, it is lubricated that effect mainly contains one, between moving parts, provides film lubrication to reduce friction and to wear and tear; The 2nd, cooling is taken away the heat cooling effect as thermal medium from critical surface; The 3rd, sealing, filling casing wall, the injustice place on valve stem surface and in the oil sealing of turbocharger, sealing; The 4th, cleaning is taken back sump through flowing of machine oil with the carbide on the part, greasy filth, the logical circulation of wear metal particle, and is unlikely at piece surface formation incrustation; The 5th, damping and buffering effect, particularly high pressure parts are like gear and push rod etc.; The 6th, anti-oxidation and corrosiveness shield to part.Machine oil through after a while work, has been brought into play after the above-mentioned function contaminated and the mistake effect need be changed in machine.In order to prolong the service life of machine oil, the most frequently used method is to use oil strainer, returns machine relaying supervention behind the contaminant filter that oil circulation is taken back and waves due function.The oil strainer that uses at present; All mainly to be filtered into main means; Can only filter the visible impurity in the machine oil, reduce the possibility that parts are worn, but can't stop the inefficacy speed of machine oil; Generate free radical because the main cause that machine oil lost efficacy is the molecular chain rupture of oil, the very low machine oil that finally causes of the molecular weight of these free radicals loses use value.

The utility model content

Deficiency to above-mentioned prior art; The utility model is set about from the material principle of compositionality of machine oil; Proposed a kind of solution of compound rare-earth foam metal oil renewal, purpose is with rational structure more and extraordinary filter material the macromolecular chain that causes inefficacy machine oil to be repaired, thereby makes the oil renewal of inefficacy; Prolong the Acceptable life of machine oil, bring up to existing 10 times or more than.

The utility model mainly comprises filter ruffle, matrix tube, core pipe composition.Wherein filter ruffle is an outermost layer, and the selection of filter ruffle is to be insoluble to oil to have the less special substance of water imbibition and filterability and temperature influence, can be carbon fiber yardage roll, nonwoven fabric roll, fiber paper roll; The matrix tube has then been processed certain thickness hollow tubular by the made metal foam of rare earth mixed matrix metal, and core Guan Ze is the hollow tubular that is abound with through hole that certain intensity is arranged.The matrix jacket casing in core pipe periphery, tightly is placed in filter ruffle outside the matrix tube at last.

When using the utility model; Filter ruffle is at first with the impurity particle filtering in the machine oil; Then not with granule foreign but the barrel through the matrix tube more also with the machine oil of temperature more than 100 ℃; In through the process of barrel with matrix in rare earth element come in contact, machine oil cleaved or the strand that is about to fracture have been repaired under rare earth element and uniform temperature, during the original original state of machine oil recovery gets and newly comes into operation.

The beneficial effect that the utility model compared with prior art has is that the strand of in impurity screening, effectively repairing the machine oil cleaved makes machine oil keep original state for a long time, thereby prolongs the Acceptable life of machine oil in machine.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

As shown in Figure 1, the utility model mainly comprises filter ruffle 1, matrix tube 2, core pipe 3 compositions.Wherein filter ruffle 1 is placed in outermost layer, and the selection of filter ruffle 1 is to be insoluble to oil to have the less special substance of water imbibition and filterability and temperature influence, can be carbon fiber yardage roll, nonwoven fabric roll, fiber paper roll; Purpose is the impurity particle that is used for filtering machine oil, and the thickness minimum of filter ruffle 1 is not less than 10mm.2 in the matrix tube in intermediate layer is processed hollow tubular by the made metal foam of rare earth mixed matrix metal, and barrel has certain thickness, and this thickness minimum is not less than 10mm; Rare earth element in the matrix tube 2 can impel machine oil cleaved and the strand reparation that is about to fracture to ensure that machine oil did not lose efficacy with contacting of machine oil at a certain temperature; With the write in reply carrier of rare-earth elements of metal foam; Main cause is that the metal foam porosity is up to more than 90%; Have certain intensity and rigidity, have more high aeration, high-specific surface area and capillary force, high-specific surface area can ensure that rare earth element carries out high efficiency reparation with fully contacting of machine oil; High capillary force then can have been guaranteed the minimizing of machine oil filtration resistance.Core pipe 3 tightly is placed in the hollow lumen of matrix tube 2, is the hollow tubular that is abound with through hole that certain intensity is arranged, and its effect mainly is to be used for compiling and to guide to be filtered getting back to the accurate machine that gets into of oil-out with the machine oil of reparative regeneration and working on.

When using the utility model; Outermost filter ruffle 1 is at first with the impurity particle filtering in the machine oil; Then not with granule foreign but also get into again in the barrel of matrix tube 2 with the machine oil of temperature more than 100 ℃; In through the process of barrel machine oil in each hole fully and rare earth element come in contact; Machine oil cleaved or the strand that is about to rupture have been repaired under the catalysis of rare earth element and uniform temperature, and machine oil recovers original and all in core pipe 3, compiled again from the use next time of new input after the original state.

In practical application, it is hollow tubular that matrix tube 2 is not limited only to, and also can be the cup-shaped that an end has back cover.Matrix tube 2 also can be as shown in fig. 3 in addition; Being not limited only to is an open column shape; Barrel can also be provided with a circle involute groove 4, makes matrix tube 2 have fin, and machine oil more quick service reinstate rate is higher with contact velocity rare earth and the mezzanine space between per two fins can make.
