Abstract

The utility model discloses an automobile magnetic filter cleaner. The structure characteristic of the utility model is that the structure of a filter cartridge is changed. An upper lid and a lower lid clamp a metal mesh in the shape of a circular pipe and a supporting piece to form a filtering device. An absorption device composed of a magnetic loop is fixed and connected around the hole adapting with the oil port on the upper lid to absorb ferruginous chippings and suspended solid. A safety valve is connected with the hole on the lower lid to solve the problem of insufficient oil supply of cold start and metal mesh blockage. The utility model has the advantages that the structure is simple, the component is less and wearable, the installation is easy, the cost is low, and the repeated use is possible; the impurity such as iron can be effectively filtered out, the wearing of the workpiece can be postponed, and the socioeconomic performance is excellent.

Description

The automobile magnetic filter

Technical field

The utility model relates to a kind of automobile magnetic filter, and the motor oils such as filtering installation, particularly automobile that belong to the solid, liquid separation filter the filtering installation that has magnetic force filtering iron powder impurity of usefulness.

Background technology

In field of internal combustion engine, traditional oil filtration product, it generally is the disposable use structure that refill filters, can only the bigger solid impurities of filtering, can't filtering to the ferrous metal break flour that produces in the parts operation process, thereby quicken machine members, in recent years for addressing this problem, have the lubricating oil filter of magnetic and disclose some, absorption ferrimagnetism break flour, its weak point is the structure more complicated, parts are many, increased productive costs, still adopted refill to filter, filtration resistance is big, be easy to stop up, cause the fuel feeding deficiency, have because in the middle of magnetic substance is suspended from, the iron impurity that has in the machine oil partly can not be by filtering.

Summary of the invention

It is a kind of simple in structure that the purpose of this utility model is to provide, and assembly is few durable in use, installs easily, cheap, effectively the repeatedly used automobile magnetic filter of filtering particulate matter and irony chip and suspended matter thereof.

For achieving the above object, the technical solution of the utility model is on the basis of existing technology, mainly changed the technical design of cartridge type filter, this cartridge type filter is by the metal gauze and the strut member of upper and lower cover clamping filtration, form filtering installation, the hole and the oil outlet of loam cake are adaptive, an affixed magnet ring around the face in tube with the high-performance rare-earth material, become the absorption facility of ferrous metal powder and suspended matter, one side connects a safety valve in the hole tube of lower cover, the big and under-supply defective of metal gauze obstruction machine oil of lubricating oil granularity when solving cold start-up.

Description of drawings

Accompanying drawing is the utility model structure cross-sectional schematic.1-exterior seal ring among the figure, the 2-adapter plate, the 3-inner seal ring, the 4-loam cake, the 5-metal gauze, the 6-lower cover, 7-press-fits spring, 8-shell, 9-safety valve, 10-strut member, 11-magnet ring, 12-enclosing cover, 13-fuel feed hole, 14-oil outlet.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail, and provides embodiment.

Present embodiment is the permanent affixed disposable automobile magnetic filter of shell and enclosing cover.

This automobile magnetic filter comprises shell 5, enclosing cover 12, adapter plate 2, press-fit spring 7 and cartridge type filter, it is characterized in that cartridge type filter is by metal gauze 5, strut member 10, on,

lower cover

4,6, magnet ring 11 and safety valve 9 are formed, metal gauze 5 and strut member 10 be mutually near, contour round tube shape, metal gauze 5 is made by stainless steel material, strut member 10 plays a supportive role, in order to avoid metal gauze is bent distortion, staggered uniform hole is arranged on its tube wall, on, lower cover 4, respectively be provided with a hole on 6, periphery respectively is provided with a groove, oil outlet 14 on the hole of loam cake 4 and the adapter plate 2 is adaptive, with groove one side in the same way, be connected with a usefulness high-performance rare-earth permanent magnet material around the hole and make magnet ring 11, one clamping platform is arranged around the hole of lower cover 6 and groove one side in the same way, with safety valve 9 tight clampings, the two ends of metal gauze 5 and strut member 10 are snapped in respectively, form a complete metal gauze oil-feed, loam cake oil-out cartridge type filter in the groove of lower cover.Safety valve 9 be by have at the bottom of the tube one with lower cover 6 on the cylinder of clamping platform clamping annulus, be provided with a diameter greater than clamping flat-bed base plate in the tube, be provided with on the base plate by the fixing spring of last nozzle and form.On the enclosing cover 12 on greater than adapter plate 2 fuel feed hole 13 around the outside flared horn of a circle is arranged, snap in exterior seal ring 1 with slip-off preventing, enclosing cover 12 can be disposable permanent affixed with the consolidation method of shell 8.Also can be that dismoutabilities such as screw thread, screw, clamping are affixed, be convenient to regular cleaning, repeated use, cut down expenses.

It installs and uses process is on the holddown spring 7 on being placed on the cartridge type filter lower cover at the bottom of the shell, cover on the cartridge type filter and place inner seal ring 3, be pressed into adapter plate 2 and connect enclosing cover, again whole fil is connected with the oil inlet of driving engine with the screw thread in the oil outlet 14, exterior seal ring 1 nature is with the peripheral sealing of oil inlet and the connection of the oil outlet and the fil of driving engine, form mutually and isolate, the path of circulating filtration, when cold start-up, big or the metal gauze obstruction because of engine oil viscosity, when being difficult for by cartridge type filter, the cartridge type filter external pressure increases, and then backs down safety valve, oil directly enters the cartridge type filter fuel feeding, has guaranteed the normal operation of machine.

In sum, the utility model is simple in structure, assembly is few and durable in use, installation is easy, cost is low, but repeated use also, solve cold start-up and metal gauze and stopped up the fuel feeding deficiency, filtering particulate matter and irony chip impurity and suspended matter thereof have delayed component wear effectively, and be social, good in economic efficiency.
