Abstract
The present invention relates to a filter assembly in which a filter, having a plurality of micropores i.e. openings, which are open in a thickness direction thereof in a state of being extended horizontally or inclinedly with respect to a flow direction of a fluid containing solid foreign substances and have a tapered shape gradually narrowing from upstream ends to downstream ends thereof, is installed communicatively with an upstream end of a branch pipe interposed in a portion of a flow pipe through which the fluid containing the solid foreign substances flows so as to form, in conjunction with the flow pipe, a filtered flow path which passes through the filter and an unfiltered flow path which does not pass through the filter. Therefore, the problem can be solved.
Claims15
A filter assembly comprising:
- a flow pipe, having a flow path from a front end of the flow pipe towards a rear end of the flow pipe, wherein a fluid flows along the flow path in the flow pipe;
- a filter portion, being positioned in the flow pipe, including;
- a non-metal filter, being positioned in the flow pipe, having a first end adjacent to the front end and a second end adjacent to the rear end, being extended from the first end to the second end;
- and
- a plurality of micropores being formed on the non-metal filter;
- and
- a branch pipe being connected to the second end of the non-metal filter,
- wherein the non-metal filter has an outer surface and an inner surface opposite to the outer surface,
- wherein the outer surface faces the flow pipe,
- wherein the plurality of micropores are connected to the outer and inner surfaces,
- wherein a diameter of each of the plurality of micropores decreases from the outer surface towards the inner surface,
- wherein the branch pipe faces the inner surface,
- wherein the branch pipe extends from the second end to an outside of the flow pipe, and
- wherein a portion of the fluid flows from the flow pipe to the branch pipe through the plurality of microscopes.
