Description

A kind of device for separating oil and iron powder of oil filter

Technical field

The utility model relate to a kind of from fluid the magnetic separation of separating solids material, particularly a kind of device for separating oil and iron powder of oil filter.

Background technology

When motion mechanical wear such as the engine of automobile or diesel vehicle, the pump in the hydraulic system, valve, cylinder, gear all can produce metal powder grain, needs immediately these iron powders are separated from oil, guarantees that machinery normally moves and increases the service life.Separator commonly used is paper or wire netting candle filter, and its shortcoming is, the life-span of filter core is short, is disposable filter, the cost of use height, and the 2nd, the poor filtration effect to iron powder below 0.1 micron can not reach the requirement of secondary filter.For head it off CN01234155 patent disclosure a solution, be provided with the magnet of endless belt oilhole at the oil-out place of filter core, but this device has taken the inner space of filter core owing to be provided in a side of in the filter core, the gap in magnet space is narrow and small, easily filter core is stopped up, its service life is shorter, is not easy to change, together scrap in company with filter, increased cost of use.The patent No. provides a kind of technical scheme for 03256048.6 patent, outside filter head housings, be provided with a watt shape magnet arrangement, its advantage is easy to loading and unloading, magnet can be repeatedly used, cost of use is low, but, the circulation area of oil is reduced, thereby the still unresolved iron powder of this technical scheme influence the problem in service life of filter because iron powder is adsorbed on the inwall of the outer filter housing of filter core.

Summary of the invention

The utility model technical issues that need to address are a kind of device for separating oil and iron powder of oil filter of design, and the good separating effect of this separator is easy to loading and unloading, reusable and filter core long service life.The technical solution of the utility model is, a kind of device for separating oil and iron powder of oil filter, it comprises filter core, filter housing and magnet, it is characterized in that: the ozzle that is provided with screw thread on the filter housing end face matches with the screwed hole of oil filter base, between the end face of filter housing end face and oil filter base, be provided with an annular cover, magnet places on the inwall of annular cover, cavity between ozzle and the magnet is communicated with the cavity of filter core and filter housing and the fuel feed hole in the oily filter base, and the filter core inner chamber is communicated with the spill port that ozzle endoporus and oil are filtered in the base.The utility model is owing to be provided with magnet mechanism between filter and filter base, thereby has good filtration effect compared with the prior art, and is easy to loading and unloading, reusable and have a prolongation filter core advantage in service life.

Description of drawings

Accompanying drawing is a structural representation of the present utility model.

The specific embodiment

The utility model is described in further detail in conjunction with above accompanying drawing, filter housing 8 one ends are provided with a screwed hole of filtering base 2 with externally threaded ozzle 6 and oil and match, between filter housing and oil filter base, be provided with an annular cover 4, magnet 5 is contained on the inwall of this annular cover, between the end face of annular cover and oil filter base, be provided with sealing ring 3, also be provided with sealing ring between the end face of annular cover and filter housing.Oil filter base is provided with fuel feed hole 1, and its outer end is communicated with the oil outlet of engine, and cavity in its endoporus and the annular cover and filter housing are communicated with cavity between filter core, the cavity of filter core and ozzle and oilyly filter the interior oil duct of base and the oil return opening of engine is communicated with.

The principle that oil of the present utility model separates with iron powder is, the oil that engine or hydraulic oil system come out is in oil filter base aperture is being flowed through the annular cover, be subjected to the magneticaction of magnet, iron powder in the oil is attracted on the surface of magnet, and oil filters after the drainback passage in ozzle and the oil filter base is got back in the engine (or hydraulic system) through filter core 7.When oil filter reaches guideline lives and scraps, only need that filter is screwed down the filter that more renews from oil filter base and get final product, and annular cover and the magnet in it does not need to change, and are can reuse after the iron powder on the magnet surface is cleaned.This iron powder separator for oil does not influence filter space, thereby its filter effect is better.

Claims (1)

1, a kind of device for separating oil and iron powder of oil filter, it comprises filter core, filter housing and magnet, it is characterized in that: the ozzle that is provided with screw thread on the filter housing end face matches with the screwed hole of oil filter base, between the end face of filter housing end face and oil filter base, be provided with an annular cover, magnet places on the inwall of annular cover, cavity between ozzle and the magnet is communicated with the cavity of filter core and filter housing and the fuel feed hole in the oily filter base, and the filter core inner chamber is communicated with the spill port that ozzle endoporus and oil are filtered in the base.
