Abstract

An electromagnetic oil filter for IC engine is composed of upper and lower casings, back cover, wound-type coarse filter, electromagnetic coil, metal filter, paper fine filter and oil inlet tube. The upper casing is in threaded connection with the oil inlet pipe, the lower casing is in threaded connection with the upper casing, the rear cover is in threaded connection with the lower casing, the metal filter is arranged on the filter base of the internal combustion engine through the oil inlet pipe in a penetrating mode and is fixed to the upper portion of the lower casing, the electromagnetic coil is sleeved on the periphery of the outer side of the lower casing and located between the lower casing and the rear cover, and the bottom end of the rear cover is provided with the oil drainage plug. The electromagnetic type oil filter is simple to manufacture, good in purification effect, high in reliability, economical and durable. The oil pan can prevent the repeated abrasion when the engine oil in the oil pan of the internal combustion engine reenters the part needing lubrication, thereby achieving the purposes of prolonging the service life of the internal combustion engine and reducing the noise.

Description

A kind of electromagnetic engine oil filter for I. C. engine

(1) technical field

The present invention relates to a kind of I. C. engine oil filter, relate in particular to a kind of electromagnetic engine oil filter for I. C. engine.

(2) background technology

The machine oil of lubricate in the internal combustion engine, because each part friction of internal combustion engine has produced metal filings, the dust in solia particle in the combustion chamber and carbon distribution and the environment, what these objectionable impurities were all unavoidable sneaks in the machine oil.Along with running up of machinery will inevitably be caused the heavy wear of moving component, even piece surface is seriously pulled.Even more serious is that the oil circuit of lubricating system is stopped up, and causes the generation of major accidents such as " tile kilnings ".So the lubricating oil of internal combustion engine before delivering to lubricated friction surface, must filter lubricating oil, just can not make mechanical parts cause the generation of repeated wear and " tile kilning " accident.At present, the oil filter of internal combustion engine use both at home and abroad can be divided into by the filtering mode: filtering type and centrifugal two classes.The filtering type cleaner can be divided into again by its version: Wiper blade type, Wound-rotor type and papery filer element type.Above-mentioned several oil filter all exists circulating resistance in varying degrees, the great purge difficulty, and the life-span is short, and manufacturing cost is high and can not filter metal filings in the machine oil, and metal filings causes the main cause of internal combustion engine moving component repeated wear just.How at internal combustion engine a kind of filter being installed, effectively removing the metal filings in the machine oil, is the new problem of some expert's researchs.

(3) summary of the invention

The technical problem to be solved in the present invention, it is little to provide a kind of circulating resistance, and it is convenient to clean, and the life-span is long, effectively removes the electromagnetic engine oil filter for I. C. engine of interior slag of I. C. engine oil and metal filings.

The technical scheme that adopts is:

A kind of electromagnetic engine oil filter for I. C. engine comprises upper shell, lower house, bonnet, Wound-rotor type coarse filter, solenoid, metallic filter, papery fine cleaner, oil inlet pipe.Upper shell is threaded with oil inlet pipe, lower house is threaded with upper shell, bonnet is threaded with lower house, be contained on the IC engine cleaner seat by oil inlet pipe, described metallic filter is installed on the oil inlet pipe and is contained in the lower house internal upper part and fixes, solenoid is sleeved on the lower house outer periphery, and between lower house and bonnet, the bonnet bottom is provided with the plug of draining the oil.

Above-mentioned papery fine cleaner is contained in the upper shell, fixes by steel shim.

Above-mentioned Wound-rotor type coarse filter is threaded in the oil inlet pipe lower end, is positioned at the lower house bottom.

The good effect that the present invention obtains is: this electromagnetic engine oil filter can be installed on the regular engine oil cleaner mount pad of all models by the size that changes housing and bonnet, when internal combustion engine, as long as connect the circuit of solenoid, metallic filter inside just forms very strong magnetic field, after cleaner pressure inside machine oil filters through the Wound-rotor type coarse filter, during again by metallic filter, metal filings of being sneaked in the machine oil and metal are greasy just to be adsorbed in the metallic filter owing to the effect of electromagnetism, thereby machine oil is purified.This electromagnetic engine oil filter is made simple, good purification, reliability height, economy and durability.The machine oil that can prevent I. C. engine oil drain pan inside enters when needing lubricated position again and duplicates wearing and tearing, thereby reaches the purpose that prolongs internal combustion engine service life and reduce noise.

Fig. 1 is a structural representation of the present invention.

Fig. 2 is the circuit diagram of solenoid of the present invention.

(5) specific embodiment

A kind of electromagnetic engine oil filter for I. C. engine comprises upper shell 1, lower house 2, bonnet 3, Wound-rotor type coarse filter 6, solenoid 7, metallic filter 8, papery fine cleaner 9, oil inlet pipe 11.Upper shell 1 is threaded with oil inlet pipe 11, lower house 2 is threaded with upper shell 1, bonnet 3 is threaded with lower house 2, seal by sealing gasket between the counterpart, upper shell 1, lower house 2 and bonnet 3 connect into the sealing matrix, be installed on the IC engine cleaner seat by oil inlet pipe 11, metallic filter 8 is installed on the oil inlet pipe 11 and is contained in lower house 2 tops, solenoid 7 is contained in lower house 2 outer periphery, between lower house 2 and bonnet 3 and with bonnet 3, align, bonnet 3 bottoms are provided with the removable plug 4 of draining the oil, papery fine cleaner 9 is contained in the upper shell 1, fixing by steel shim 5, Wound-rotor type coarse filter 6 is threaded in oil inlet pipe 11 lower ends, has constituted electromagnetic engine oil filter for I. C. engine.

Operation principle:

During engine starting, oil filter is started working, machine oil enters cleaner by oil-in 12 and filters, supply internal combustion engine lubrication through oil-out 10, as long as the K switch of closed control panel is connected the circuit (see figure 2) of solenoid 7, inner and lower house 2 inside of metallic filter 8 just form very strong magnetic field, and its magnetic field has a suction-operated to metal fillings and metal are greasy, machine oil are further purified greasy be adsorbed on metallic filter 8 and the lower house 2 of the metal fillings of being sneaked in the machine oil and metal.During engine shutdown, should disconnect the K switch of electromagnetic circuit rapidly, after magnetic force disappears, be adsorbed on that metal filings on the metallic filter 8 or metal are greasy just to be deposited on the bonnet 3 owing to the effect of gravity.Internal combustion engine used 250 hours or travelled after 2000 kilometers, should pull down the plug 4 of draining the oil, the machine oil of electromagnetic engine oil filter enclosure interior is emitted, and the solid particle that is adsorbed on the papery fine cleaner 9 is got rid of filter case together with the metal filings or the greasy machine oil of just emitting together of metal that are adsorbed on the metallic filter 8 and be deposited on the bonnet 3.
