Description

TECHNICAL FIELD [0001] The present invention relates to an oil-oil separating apparatus,

The present invention relates to an oil filter separating apparatus having an oil filter function and more particularly to an oil filter apparatus for separating foreign matter from oil and a vapor oil separating apparatus for separating oil from the oil vapor, So that it can be driven by circulating oil without a power source.

Generally, the oil used to smoothly operate the driving unit in the internal combustion engine forms a vapor due to the temperature rise due to the driving friction of the driving unit, and is also contaminated.

For example, when a large amount of vapor is present in the internal combustion engine, there is a fear of explosion of the engine which is a component of the internal combustion engine. At this time, oil particles are contained in the vapor, which increases the consumption amount of the oil, and the oil around the engine is contaminated with oil. Separately, if the filter for the contaminated oil is not provided, the frictional resistance of the driving part in the internal combustion engine is greatly increased, so that the driving part is damaged by the breakage and abrasion, and smooth driving can not be achieved.

However, since a general vapor oil separator used in the above-described manner includes a separate driving motor, and various electrical components and control devices for electrically driving it are employed, it is difficult to secure space due to the enlargement of the apparatus And expensive cost burden and maintenance cost increase inevitably occurred.

Further, since the oil filter apparatus is independently manufactured and adopted separately from the above-described oil vapor separation apparatus, there is a problem that the maintenance cost is added.

The present invention has been made to solve the problems described in the background of the present invention, and it is an object of the present invention to provide an oil filter separating apparatus and an oil filter apparatus which are manufactured in a single unit structure, The purpose of the device is to provide.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a cross-sectional view illustrating a vapor oil separator having an oil filter function according to the present invention.

As shown in the drawing, a vapor oil separator 10 (hereinafter abbreviated as a separator) having an oil filter function according to the present invention includes a casing 16 formed by coupling a lower housing 12 and an upper housing 14, A centrifugal fan 20 connected to the impeller 18 to be installed on the casing 16 and connected to the impeller 18 by a centrifugal fan 20, And a centrifugal fan housing 22 installed on the casing 16 to seal the centrifugal fan housing 22.

Specifically, the casing 16 is formed by coupling the lower housing 12 and the upper housing 14. At this time, the fastening holes 24 are formed in the lower and upper housings 12 and 14 so that the coupling can be maintained. So as to be fastened to each other.

An impeller 18 is disposed in the inner space 26 of the lower housing 12. The impeller 18 has a hollow structure in which a through hole 28 is formed at the center.

A hinge portion 30 is formed integrally with the upper housing 14 at an inner center of the upper housing 14 and a connecting shaft 34 is passed through the inner hinge hole 32 of the hinge portion 30 As shown in Fig. At this time, a hooking jaw 36 is formed so that the upper end of the connecting shaft 34 can be hooked on the upper surface of the hinge 30.

The lower end of the connecting shaft 34 rotatably coupled as described above is inserted into the through hole 28 of the impeller 18 and the oil centrifugal fan 20 is fixed to the upper end of the connecting shaft 34. The structure in which the connection shaft 34 and the oil vapor centrifugal fan 20 are coupled will be described in detail below.

The connecting shaft 34 is formed with a flow hole 38 in a state of communicating with the through hole 28 of the impeller 18. The flow hole 38 is communicated with the oil outlet 38 formed in the upper housing 14, And an oil supply hole 42 is formed on the opposite side of the upper housing 14 corresponding to the oil outlet hole 40 so as to be injected to the side of the impeller 18 .

In addition, the upper housing 14 has an upper portion and a side surface opened so as to be independently formed with a vapor receiving space portion 44. Oil is gathered on the bottom surface of the thus formed vapor receiving space portion 44 And an oil return hole 48 is formed in the upper housing 14 in a state of communicating with the receiving recess 46. As shown in FIG.

A centrifugal fan housing 22 is installed on the upper surface of the casing 16 in a state where the centrifugal fan housing 22 communicates with the vapor storage space 44. A spiral groove 50 is formed on the inner surface of the centrifugal fan housing 22.

The oil centrifugal fan 20 installed inside the centrifugal fan housing 22 is fixed to the upper surface of the connection shaft 34 connected to the impeller 18 in a linkage manner. Specifically, the vapor centrifugal fan 20 includes a coupling member 56 that sequentially passes through the disk 52 in a state in which a plurality of disks 52 formed in a circular shape and having a hollow structure are stacked and arranged with a gap T, Is fastened to the connection shaft (34). So that it can be structured to be interlocked with the vortex centrifugal fan 20 through the connection shaft 34. (See Fig. 2)

In addition, spacing grooves 54a and 54b are formed at the tip of the inner side of the disk 52 along the tips of the disk 52. At this time, the spacing holder 54a having the gap T abuts against the upper surface of the disk 52, Are arranged along the front end in an arrangement structure in which they alternate with each other.

The upper end of the centrifugal fan housing 22 is connected to the inside of the centrifugal fan housing 22 and the upper end housing 14 is connected to the upper end of the lower end of the centrifugal fan housing 22, And communicates with the space portion (44).

The oil used in the operation of the driving unit of the internal combustion engine is first sprayed from the oil supply hole 42 and struck against the side surface of the impeller 18, do. At this time, the oil supplied to the oil supply hole 42 is pressurized by a pump (not shown) so that the impeller 18 rotates about the connection shaft 34.

When the impeller 18 rotates in this manner, the oil adhered to the surface of the impeller 18 becomes viscous, and the foreign particles P contained in the oil are adhered to the centrifugal force of the impeller 18 The oil is separated from the oil and accumulated on the wall surface of the lower housing 12.

The oil adhering to the surface of the impeller 18 flows into the lower end of the impeller 18 and meets the through hole 28 of the impeller 18. At this time, The pressure is high and the through hole 28 is in a low pressure state, so that the oil forms a flow sucked into the through hole 28. And finally discharged to the oil outlet hole 40 formed in the upper housing 14 along the oil passage 38 of the connecting shaft 34 to be circulated to the internal combustion engine.

Meanwhile, when the impeller 18 rotates, the oil centrifugal fan 20 connected to the impeller 18 rotates in a linked state. When the vapor centrifugal fan 20 rotates in this way, a suction force for guiding the vapor generated in the internal combustion engine in the discharge direction is formed.

As described above, the vapor supplied through the vapor suction pipe S1 is discharged through the vapor discharge pipe S2 while passing through the gap T of the vapor centrifugal fan 20. At this time, The oil contained in the vapor is separated due to the centrifugal force and the flow rate increase of the disk 52, and the oil is adhered to the inner surface of the centrifugal fan housing 22. [ At this time, the spiral grooves 50 are formed on the inner surface of the centrifugal fan housing 22, so that the oil that has collided is not re-dispersed.

The oil present in the helical groove 50 flows down along the helical groove 50 and accumulates in the receiving recess 46 of the oil accommodation space portion 44. The accumulated oil is collected in the oil recovery hole 48 To the internal combustion engine. As a result, only the oil-removed air is discharged to the vapor discharge pipe S2, thereby preventing oil contamination of the outer periphery.

The clearance T may be formed in a range of 1.5 mm to 2.0 mm as shown in FIG. For example, if the gap T is less than 1.5 mm, the gap T is formed too narrow to cause a load due to the passage of the vapor. When the gap T is formed to be 2.0 mm or more, the pressure formed in the gap T is low As a result, the oil separation performance is deteriorated due to the lowering of the suction force and the flow velocity, and explosion of the internal combustion engine due to the discharge load of the vapor may be caused.

The use of the oil filter separating apparatus 10 having the oil filter function according to the present invention enables the oil filter function for removing the foreign substances and the oil oil separating function for separating the oil from the oil vapor discharged to the internal combustion engine And a separate electric driving source is not provided, so that a simple structure can be achieved and convenience for maintenance can be provided.

Further, by recycling the oil captured from the oil vapor to the internal combustion engine, the amount of consumption of the oil can be minimized.

As described above, although the present invention has been described with reference to specific practical examples and drawings, the present invention is not limited to this. For example, it is possible to mount a motor as a driving source in a casing in which an impeller is installed, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims.
