Hybrid centrifugal filter

Abstract

The present invention relates to a hybrid centrifugal filter, and the objective of the present invention is to provide a hybrid centrifugal filter in which a separate filter member is additionally provided inside a rotor constituting a centrifuge, so as to provide advantages of both the centrifuge and a general filter, thereby improving impurity removal efficiency. To this end, the present invention provides the hybrid centrifugal filter comprising: a casing having a fluid inlet and a fluid outlet; a shaft provided inside the casing in a vertical structure and guiding, to the inside of the casing, fluid flowing in through the fluid inlet; a stand tube provided to have a rotatable structure around the shaft, and jetting the fluid flowing into the casing through the shaft; the rotor provided inside the casing so as to form a space for receiving and filtering the fluid jetted from the stand tube while the rotor rotates together with the stand tube, and having a nozzle for spraying the filtered fluid into the casing; and a filter member provided inside the rotor so as to divide the inner space of the rotor into an upper space and a lower space while having a structure extending in the longitudinal direction of the shaft, and having a plurality of flow holes for allowing the fluid jetted to the upper space from the stand tube to flow into the lower space.

Description

technical field [0001] The present invention relates to a kind of centrifuge used for filtering the impurity of fluid, relate to mixing type centrifuge more in detail, it also is provided with filter part inside the rotor (rotor), thereby makes the contact surface area with impurity increase, Therefore, the overall removal efficiency of impurities including fine particles of 10 μm or less is improved. Background technique [0002] Generally, a centrifugal separator (Centrifugal Filter) is a device that uses centrifugal force to separate / refine / concentrate components or substances with different specific gravity, and the centrifugal separator is also used to filter impurities of fluid. [0003] figure 1 It is a cross-sectional view showing the structure of a conventional centrifuge. [0004] shown in figure 1 A centrifuge is a centrifuge used to filter impurities from a fluid used in an engine. [0005] Described centrifuge comprises: shaft 10, and it is formed with flow ...

AI Technical Summary

Problems solved by technology

[0008] However, the centrifuge as described above has the disadvantage of reducing the filtration efficiency of particles with a particle size of 10 μm or less.

In other words, the smaller the particle size of the impurity, the less affected by the centrifugal force, and the small impurity particles cannot reach the paper installed on the inner surface of the rotor 20 and fall together with the fluid. Therefore, it is considered that the existing centrifuge cannot filter Microparticles with a particle size of 10 μm or less

[0009] Finally, the existing centrifuge has the advantage of being able to filter a large amount of impurities, on the contrary, it has the disadvantage of low filtration efficiency for particles below 10 μm

[0010] In addition, in the case of a general filter having a structure that allows only particles of a certain size or less to pass through, depending on its structure, it has the advantage of being able to smoothly remove impurities containing a particle size of 10 μm or less. On the contrary, it has the disadvantage that it cannot handle a large amount of impurities, and over time the filtered impurities build up on the surface, thereby increasing the resistance of the fluid to flow, thus ultimately requiring frequent replacement
