Centrifugal filter

摘要

Disclosed herein is a centrifugal filter. The centrifugal filter includes a shaft, a rotor housing which rotates around the shaft and has filter paper on the inner side surface thereof, a spindle tube which rotates along with the rotor housing around the shaft and discharges the fluid from the shaft into the rotor housing, and a separation film which separates an internal space of the rotor housing into upper and lower portions so that impurities that are removed from the fluid by means of centrifugal force are deposited in the upper portion of the internal space while filtered fluid flows into the lower portion of the internal space. A dispersing means is provided on the spindle tube to make a cross-sectional shape of the fluid discharged from the spindle tube into the rotor housing be an elongated shape so that the fluid is widely dispersed into the rotor housing.

1. A centrifugal filter, comprising: a shaft (110) defining a passage therein through which fluid enters the centrifugal filter; a rotor housing (120) rotating around the shaft (110) and generating centrifugal force, with a filter paper (1221) provided on an inner surface of a sidewall of the rotor housing (120); a spindle tube (130) rotating along with the rotor housing (120) around the shaft (110), the spindle tube (130) receiving fluid from the shaft (110) and discharging the fluid into the rotor housing (120); and a separation film (140) separating an internal space of the rotor housing (120) into upper and lower portions and into inner and outer portions so that impurities that are removed from the fluid by means of centrifugal force are deposited in the upper portion (S1) of the internal space while filtered fluid flows into the lower portion (S2) of the internal space and is then discharged through a nozzle (150) provided in a lower end of the rotor housing (120),
wherein dispersing means is provided on the spindle tube (130) to make a cross-sectional shape of the fluid discharged from the spindle tube (130) into the rotor housing (120) be an elongated shape so that the fluid is widely dispersed into the rotor housing (120).
