Description

Technical Field

The invention relates to the technical field of engine oil filtration of internal combustion engines, in particular to an engine oil filter which can effectively filter and separate large and small metal particles in engine oil, improve power, reduce oil consumption and prolong the service life of the engine.

Background

The engine oil, namely engine lubricating oil, can play roles in lubricating, antifriction, sealing, cooling, cleaning, rust prevention, corrosion prevention and the like for an engine, the performance of the engine oil affects the working efficiency and even the service life of the engine, and compared with high-grade engine oil, the common engine oil has low price, but has poor lubricating effect and short service life. However, no matter common engine oil or high-grade engine oil is used, substances with lubricating effects in the engine oil change in the high-temperature environment in the engine, so that the lubricating effects of the engine oil are reduced to different degrees along with the increment of the service time. Particularly, when the engine works, metal substances and carbon deposition impurities generated by mechanical abrasion between parts are mixed into engine oil, so that the purity viscosity and the lubricity of the engine oil are reduced, the adhesive force, the fluidity and the sealing property are deteriorated, and an oil film protective layer on the surface of the parts is thinned. Therefore, the friction assistance among engine parts is increased, the power performance of the engine is reduced, the service life of the engine is shortened, and meanwhile, the fuel loss and the exhaust emission are increased, so that the environment is polluted.

Mechanical wear between the components of the engine during operation naturally produces particles of metallic material that contain large particulate metals that are detrimental to the lubricating effect, as well as fine (micron, nanometer-sized) non-detrimental particulate metallic materials that must be removed. The tiny metal particles are magnetized by a magnetic field and become beneficial magnetic metal substances, the beneficial magnetic metal substances are mixed in engine oil, and the beneficial magnetic metal substances are automatically adsorbed on the surface of a machine part when an engine works, so that a lubricating oil film layer is formed, mechanical parts can be lubricated better, and damage to the surfaces of the parts can be repaired and protected. Therefore, how to remove large-particle metal in the engine oil, while retaining beneficial small-particle metal in the engine oil is a key to improving the lubricating effect of the engine oil. To this need, chinese patent CN103061849a discloses a novel oil magnetizing and filtering device, in which a magnet is supported by a supporting member and disposed in the filter element, after the oil passes through the filter element, metal substances in the oil can be adsorbed by the magnet, and the size of the magnetic field intensity is adjusted to distinguish and adsorb large metal particles and small metal particles. However, this oil magnetizing filter device has the following drawbacks: 1. the magnetic field intensity difference of the magnets with the same size and volume is greatly changed, so that the consistency of the magnetic field intensity is difficult to control, and the inconsistent magnetic field intensity leads to unstable filtering effect; 2. for engines of different types, displacement and types, the strength of a magnetic field of a magnet, the volume of the magnet and the shape of the magnet are different, so that the engine oil magnetizing and filtering device is difficult to meet the requirements of engines of different types, and has poor universality of filtering and magnetizing effects. 3. Although the high-grade engine oil contains various magnetic lubricating substances, such as magnetic metal substances (neodymium iron boron) and the like, after the engine works at high temperature, the magnetic performance of the metal substances is reduced or even eliminated along with the increment of the service time, so that the lubricating effect of the magnetic engine oil is deteriorated, the service life of the engine oil is shortened, and the power performance of the engine is reduced.

Example 1

Referring to fig. 1-9, the present embodiment provides an oil filter for improving power, reducing oil consumption, and prolonging service life of an engine, including: comprising the following steps: the shell that comprises lid casing subassembly 1 and base casing subassembly 2, base casing subassembly 2 has a plurality of inlet holes 21 and an oil outlet hole 22, and the filter core sets up in the shell and is located between inlet hole 21 and the oil outlet hole 22, still include the oil filter magnetization unit, the oil filter magnetization unit includes: the casing 41 with a cavity formed inside, and a magnetic member arranged in the casing 41, wherein the magnetic member is driven to move in the casing 41, so that the adsorption capacity of the magnetic member to substances to be filtered (namely, large and small metal particles with different particle sizes) outside the casing 41 is adjusted.

In the conventional oil filter, the oil filtering and magnetizing device generally includes only a filter element, and metal particles and other impurities are filtered by the filter element, so that the oil filter cannot selectively filter metal particles with large particle diameters and retain metal particles with small particle diameters, and thus cannot effectively improve engine performance. The particle size is generally differentiated by changing the degree of porosity of the filter material in the filter element, but this type of filtration is only capable of retaining large metal particles, unlike the intended purpose. In addition, the filter element has the problems of aging and the like in the use process, and needs to be replaced regularly, so that the filter element cannot achieve the purpose by adopting a filtering mode. Taking the substance to be adsorbed as metal particles as an example, the working principle of the oil filter of the embodiment is described in detail:

the magnetic member has a certain adsorption capacity to both large and small metal particles, and because the magnetic member makes the metal particles arranged in the sleeve 41 and exist outside the sleeve 41, when the adsorption capacity of the magnetic member is strong, the large and small metal particles are adsorbed on the sleeve 41, at this time, by adjusting the adsorption capacity of the magnetic member, for example, the magnetic member is moved to a position far away from the metal particles, at this time, the adsorption capacity of the magnetic member to the metal particles is reduced, the small-particle-diameter metal particles are carried by the flowing engine oil to flow back into the engine from the oil outlet 22, and the large-particle-diameter metal particles are firmly adsorbed on the sleeve 41. In addition, in the embodiment, the rotary motion of the magnetic component is driven by the flow of engine oil, and an electric driving part is not required to be designed for the magnetic component, so that an external power supply is not required, the application range of the engine oil filter is further improved, and the cost and the manufacturing difficulty are saved.

In particular, the fluid drive component is preferably, but not limited to: the engine oil filter comprises a rotating slurry fixedly sleeved on the driving shaft 43 in the center, wherein the rotating slurry is provided with a spiral blade 45 obliquely arranged, and when the engine oil passes through the engine oil filter in the embodiment, the fluid force drives the spiral blade 45 and the rotating slurry to rotate, so that the driving shaft 43 and the magnetic component are driven to rotate. The design has the advantages that: the rotary motion of the magnetic component is driven by the flow of engine oil, and an electric driving part is not required to be designed for the magnetic component, so that an external power supply is not required, the application range of the engine oil filter of the embodiment is further improved, and the cost and the manufacturing difficulty are saved. Further preferably, the spiral blades 45 are uniformly distributed along the circumference of the propeller, and the number of the spiral blades 45 is three. The helical blade 45 is disposed inclined by 60 ° with respect to the horizontal direction.

In this embodiment, the magnetic member is preferably a radially magnetized cylindrical magnet, and the working process of the engine oil filter in this embodiment is described in a state that the cylindrical magnet rotates at a constant speed: firstly, analyzing stress conditions of metal particles:

before describing the working principle of the engine oil filter for improving power, reducing oil consumption and prolonging the service life of an engine in the embodiment, firstly, referring to fig. 10, the stress condition of metal particles is analyzed, in fig. 10, a cylindrical magnetic member is taken as an example to show the approximate distribution condition of magnetic induction lines, the density of the magnetic induction lines near two ends of a magnetic pole is the largest, and the corresponding adsorption capacity to the metal particles is stronger; and the magnetic induction linear density of the region between the N pole and the S pole is relatively smaller, the weaker the adsorption capacity to the metal particles is. The direction of the attraction force of the cylindrical magnetic member to the metal particles can be regarded as being approximately directed in the direction of the center of the circle of the cylindrical magnetic member.

1. When the magnetic member rotates, the positions of the N pole and the S pole are changed, so that the magnetic induction linear density around the magnetic member is changed, and the adsorbed metal particles are reduced by the adsorption force of the magnetic member on the region of the sleeve 41 with reduced magnetic induction linear density, so that the flowing engine oil is easy to wash away the metal particles with small particle size.

2. On the other hand, in the rotating process of the magnetic member, the stress direction of the metal particles is changed, so that the metal particles have a movement trend of rotating together with the magnetic member, and the resultant force applied to the metal particles is reflected to the resultant force applied to the metal particles, and the resultant force applied to the outer wall of the sleeve 1 by the magnetic member in the direction of the metal particles is reduced, so that the metal particles with small particle sizes are easily washed away by engine oil.

In this embodiment, the movement form of the magnetic member is not limited to rotation, but may be translational movement, or a combination of both, and when the magnetic member is translated under the drive, for example, reciprocating translational movement, the magnetic member can be close to or far away from one side of the sleeve 41, so that more metal particles are easily adsorbed on the side of the sleeve 41 close to the magnetic member, and the metal particles on the other side far from the magnetic member are easily washed away by engine oil. It follows that the degree of concentration of the magnetically induced lines on the sleeve 41 must be varied as long as the magnetic member is moved, so that the metal of the large and small particles must be distinguished, and the different movement patterns are only distinguished by the good or bad effect of distinguishing the large and small metal particles.

It should be noted that: the movement form of the magnetic member is not limited to uniform movement, intermittent movement or variable speed movement, or any two of the three, or a combined movement of the three.

In the moving process of the magnetic component, the moving speed of the magnetic component can also have a certain influence on the adsorption effect of the metal particles, but the rotating speed of the magnetic component is not linearly related to the filtering effect of the metal particles. In actual use, when the magnetizing degree of the magnetic member has a certain difference relative to a preset standard value, the adsorption capacity of the magnetic member to the metal particles can be adjusted by adjusting the movement rate, such as the rotating speed, of the core member. Compared with a filtering mechanism with a fixed magnetic field in the prior art, the oil filter has low magnetizing precision requirements on the magnetic component and has a wider application range. Specifically, the application range is wider in that: when the engine oil filter for improving the power, reducing the oil consumption and prolonging the service life of the engine is applied to engines of different types, the adsorption capacity to metal particles can be adjusted by adjusting the rotating speed, so that the engine oil filter for improving the power, reducing the oil consumption and prolonging the service life of the engine is applicable to engines of different types, is not limited by factors such as the magnetic field strength, the volume, the shape and the like of a magnetic component, and has an improved application range.

In order to ensure that the magnetic members are easily mounted and dismounted and can be firmly and relatively fixedly connected with the cap housing assembly 1. In this embodiment, preferably, the cover housing assembly 1 further has a barb 13 for keeping relatively fixed with the oil filtering and magnetizing device, and a flange is formed on the sleeve 41 of the oil filtering and magnetizing device, and the barb 13 hooks the flange. And, still be provided with elastic support structure between lid casing subassembly 1 and the oil filter magnetization device, elastic support structure includes: the spring support column formed on the cover shell assembly 1, the spring fixing groove formed on the top of the oil filtering and magnetizing device and the support spring are arranged between the spring support column and the spring fixing groove.

In addition, in order to further facilitate positioning of the oil magnetizing and filtering mechanism, an open accommodation groove is further formed above the filtering material support, and a flange of a second portion is formed corresponding to the accommodation groove, and is positioned in the accommodation groove.

For convenient installation and disassembly, the cover shell assembly 1 and the base shell assembly 2 are connected in a threaded connection mode. For the base housing assembly 2, the base housing assembly 2 comprises a base housing 23, the oil outlet 22 is formed at the bottom of the base housing 23, and the oil inlet 21 is formed at the periphery of the oil outlet 22; the base housing 23 further comprises threads for connection to the lid housing assembly 1; the outline of the base shell 23 is in a polygonal fillet structure. As one preferable embodiment, the oil outlet 22 is formed at a central position of the bottom of the base housing 23, and the oil inlet 21 is circumferentially distributed on the base housing 23 around the oil outlet 22.

The oil filter of this embodiment still possesses simple to operate, dismouting advantage fast, and specifically, lid casing subassembly 1 and oil filter magnetization unit are installed through couple and spring and are later regard as an assembly, and base casing subassembly 2 and filter core, check pad and other structures are installed later regard as the second assembly, because lid casing subassembly 1 and base casing subassembly 2 are threaded connection, just so can rotate lid casing subassembly 1 after aligning fashioned accommodation groove on oil filter magnetization unit and the filter material support and link together two assemblies. The disassembly and assembly process is opposite to the installation process.

For the filter cartridge, a preferred embodiment is: the filter element 3 comprises a filter material 31 and a filter material support 32, the filter material support 32 is of a detachable structure or an integrated structure, a sealing gasket is arranged on the upper portion of the filter material support 32, a groove for placing a rubber check pad 33 is arranged on the bottom of the filter material support 32, and the rubber check pad 33 covers the oil inlet hole 21. The base housing assembly 2 is provided with a positioning groove corresponding to the contour of the rubber check pad 33. The filter material support 32 is a hollow grid-shaped framework structure, and comprises an upper framework and a lower framework.
