Description

Magnetic Field Gradient Enhanced Magnetic Oil Filter

The present invention utilizes a strong magnetic suction force generated by a magnetic structure attached to the outside of the surface of the oil filter and the like to attract the iron particles to the inside of the oil filter and the like to be attached to the inner surface to efficiently filter the iron wear particles. Magnetic gradient filter to increase the magnetic field gradient.

In general, most mechanical devices, such as vehicle engines, are made of metal parts that are rotating or moving in a straight line or the like, and wear occurs inevitably because these metal parts move in contact with each other. Therefore, in order to prevent wear and friction of the metal parts, in the case of a vehicle engine, engine oil is supplied to lubricate.

However, the engine oil supplied for this action not only degrades performance and quality over time, but also it is virtually impossible for the metal parts to completely prevent wear due to friction, which causes the metal parts to generate metal particles. Let's go.

In addition, because the surface of the metal part is irregular in microscopic size, the motion of the metal part in contact can break the fine parts of the metal part in the sub-micron or larger size range. The metal particles generated from these metal parts circulate with the enzymatic oil, thereby circulating between the precise play between the drive parts of the engine.

The general play of the drives of the engine is between 5 and 25 microns, for example, the play between the piston ring and the cylinder wall is about 5 microns. However, most conventional oil filters for filtering metal particles have filter elements consisting of paper having a pore size of about 40 microns, which allows metal particles smaller than 40 microns to pass through the paper element. . Thus, particles approaching the fine play size can pass through the paper element and then get caught in the fine play and scratch the surfaces of the metal parts, causing damage to the engine's wear leading to a decrease in engine power. In addition, when driving an engine worn vehicle, the driver may feel soft and loose.

Among the metal particles produced by the wear of these metal parts, iron particles of 20 microns or less are the most deadly for engine wear, and these iron particles are the linear, crankshaft, timing gear and valve trains in the engine. It is created by the friction between the surfaces of the metal parts, such as These iron wear particles act as catalysts in the formation of softer metals in the engine and as co-catalysts in the oxidation of oils leading to the formation of corrosive acids, sludges and varnishes.

As such, in order to reduce engine wear, wear rate, and oxidation rate, it is very important to prevent these fine iron particles from entering the oil circulation system via magnetic filtration. As iron particles are ferromagnetic, magnetic filtration methods have been used. The magnetic filtration method used permanent magnets to capture iron particles and confine them inside the wall of the oil filter, but was not effective at capturing iron particles less than 20 microns.

Therefore, for successful magnetic filtration, it is necessary to capture iron particles of 20 microns or less, and the development of an oil filter that allows the iron particles to be confined inside the oil filter wall even under turbulent flow of oil and sudden pressure changes in the oil filter. It became necessary.

By having a structure in which the inclination is improved, due to the increase in the strength of the magnetic force for pulling and fixing the fine iron powder when attached to the case 21 of the oil filter 20 by the housing 220, the general magnets having the same mass Much finer iron powder than the combination can be fixed inside the oil filter 20 by magnetic force.

10 is a perspective view showing another embodiment of the magnetic field gradient enhanced iron particle filter according to the present invention.

As shown in FIG. 10, the magnetic field gradient enhancing iron particle filter 300 according to the present embodiment is similar to the iron powder filter 200 of the magnetic field gradient increasing magnetic oil filter 20 according to the second embodiment of the present invention. Having a configuration, the magnet structure 310 is installed in the housing 320 in a plurality at intervals, which will be described as follows.

The housing 320 has a plurality of mounting grooves 321 for mounting the magnet structure 310 so as to be spaced apart from each other along the outer surface of the case 21 (shown in FIG. 7) of the oil filter 20 (shown in FIG. 7). It is formed, and each of the plurality of magnet structure 310 is mounted in the mounting groove 321, respectively. Accordingly, the number of the magnet structure 310 having four magnets as a basic unit may be one or more multiples so as to surround or completely cover a portion of the oil filter 20 or the oil pan.

In addition, in the magnet structures 310, the iron plate 330 for shielding the magnetic field is contacted to the opposite side of the oil filter 20 (shown in FIG. 7), and the iron plate 330 is made of a single or magnet as in the present embodiment. A plurality of structures 310 may correspond to each other. And, the iron plate 330 is inserted into the insertion groove 222 is formed to be connected to the mounting groove 321 perpendicular to the housing 320, the magnet structure 310 when inserted into the insertion groove 222. Is in contact with.

According to the magnetic field gradient enhancing iron particle filter 300 according to another embodiment of the present invention, not only can be easily mounted on the curvature portion of the case 21 of the oil filter 20, but also has a structure in which the slope of the magnetic field is improved. Since the branched magnetic structure 310 is mounted and mounted in plural along the outer surface of the oil filter 20 (shown in FIG. 7), the reliability of the iron powder fixing in the oil filter 20 can be greatly improved.

On the other hand, the magnetic field gradient enhanced iron particle filter (100, 200, 300) according to various embodiments of the present invention as described above is attached to the case (11, 21) of the oil filter (10, 20), but not necessarily limited thereto. And may be used in addition to any spin-on oil filter, as well as oil pans such as engine oil pans or transmission oil pans. Magnetic structures with enhanced magnetic inclination strength to enhance magnetic suction force can be applied not only to applications required for iron powder filters, but also to wherever strong magnetic strength is required by the mass or volume of small magnets. For example, it can be used where a heavy object needs to be lifted or fixed by a strong magnetic force. Therefore, in the description of the magnetic field gradient enhancing iron particle filters 100, 200, and 300, descriptions regarding the installation positions of the magnetic structures 110, 210, and 310, and the attachment positions of the iron plates 130, 230, and 330 are described in the cases 11 and 21 of the oil filters 10 and 20. Instead of the outer side, the case outer side of the oil pan may be applied.

Referring to the operation of the magnetic field gradient increasing magnetic oil filter according to the present invention as follows.

In order to capture iron particles of 20 microns or less inside the oil filters 10 and 20 by magnetic suction from the iron powder filters 100, 200 and 300 attached around the oil filters 10 and 20, the fine iron particles are captured. It is important to produce a magnetic suction that is strong enough to restrain.

In order to improve the magnetic suction force, it is necessary to increase the magnetic field or the magnetic field gradient as shown in Equation 1 below. If the magnetic field profile is rather uniform, the magnetic suction force may be small even if the magnetic field is large because the magnetic suction force is proportional to the product of the magnetic field and the magnetic field gradient. Moreover, the strength of current research magnets that can be produced is limited. If the magnets are spatially arranged to create a rapidly varying magnetic field profile in a small area, the magnetic field gradient can be improved.

That is, the design of the magnetic filtration depends on the principle of the magnetic physical properties expressed by the following equation (1).

The magnetic suction force derived from the magnet to the particle orientation (F) is the product of the magnetic field (H) and the magnetic field strength gradient (∇ H) intensity. Where χ is the magnetic susceptibility of the magnetic particles, and V is the volume of the magnetic particles. As shown in Equation 1, the strength of the magnetic suction force is proportional to the volume of the iron particles. Thus, the suction force for 1 micron iron particles is 1,000 times smaller than the suction force for 10 micron iron particles. This means that a stronger suction force is required to confine the fine iron particles on the inner side of the oil filter.

Method for increasing the magnetic suction force is to improve the magnetic field (H) and the magnetic field gradient (∇ H) acting on the iron particles. Increasing the strength of the magnetic field is expensive because a larger energy generating magnet or larger magnet must be used. On the other hand, increasing the magnetic field gradient strength is cost effective because it can be obtained from a particular arrangement of magnets. In the magnetic field gradient increasing magnetic oil filter according to the present invention, the magnetic suction force is improved by increasing the magnetic field gradient from a specific arrangement of four magnets 111, 211, and 311 having alternating magnetization directions.

As shown in FIG. 4, the magnetic field gradient increasing magnetic oil filters 10 and 20 according to the present invention utilize magnetic structures 110, 210, and 310 composed of a plurality of magnets 111, 211, and 311 having alternating magnetization directions. The magnetic poles of each of the magnets 111, 211 and 311 on one surface of the magnet structures 110, 210 and 310 are S-N-S-N poles or N-S-N-S poles in the counterclockwise direction. The magnetic field gradient is the rate of change of the magnetic field with respect to the position and is an important factor contributing to the magnetic suction force. As shown in FIG. 6, the magnetic field inclination from the magnet structure 110, 210, 310, which is composed of four magnets in which the magnetization directions alternate with respect to each other, is less than the magnetic field inclination of the magnet structure composed of magnets having the same magnetization direction and the same mass. Big. Thus, the magnetic field gradient increasing magnetic oil filter according to the present invention can greatly improve the magnetic field gradient from a specific arrangement of four magnets without adding the mass of the magnet.

In addition, in the present invention, the magnet structures 110, 210, and 310 composed of four magnets 111, 211, and 311 having alternating magnetisms have the same volume in the case of the same volume of the magnet structure composed of four magnets having the same magnetization direction. The magnetic suction force is about 2.5 times stronger than the magnetic structure consisting of two magnets. This means that with magnets of the same mass, through a particular arrangement of magnets, the magnetic suction force can be greatly increased without the use of additional magnets. In addition, since the iron plates 130, 230, and 330 having high magnetic permeability are attached to one side of the magnet structures 110, 210, and 310, the magnetic suction force and the shielding behind the magnetic field may be further improved.

The magnetic field gradient enhancing iron particle filter according to the present invention may have a planar shape or a vertical shape, and may be used for any spin-on oil filter, engine oil pan or transmission oil pan. have. By simply attaching this magnetic field gradient enhancing magnetic assembly to the outside of any spin-on oil filter, the bottom of the engine oil pan or the bottom of the transmission oil pan, the iron wear particles can be effectively filtered due to the strong magnetic suction force.

As described above, the present invention has been described with reference to the accompanying drawings, but various modifications and changes can be made without departing from the spirit of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined by the equivalents of the claims, as well as the following claims. For example, the hexahedron magnet shape can be modified in various ways, such as the outer surface of the four magnets in the shape of a disk, depending on the given situation. Can be. In addition, an example of the application to be attached to the side may be a large number of magnetic structures to cover the entire oil filter, and the spacing of the magnetic structures may be set to various sizes as necessary.
