## Abstract

Disclosed is a pore adjusting filtering apparatus including: a cylinder having a plurality of holes and in which a screw is rotatably installed; an endless track coupled to an outer peripheral surface of the cylinder by a cylinder, an endless track pin, and a support to be rotatable together with the cylinder; a fiber yarn bundle support rod inserted into the endless track to be connected to the endless track; a fiber yarn bundle, one end of which is fitted with and supported by the fiber yarn bundle support rod; a fiber yarn bundle support net for supporting the fiber yarn bundle while being attached to an outer peripheral surface of the fiber yarn bundle; a cleaning separator fixedly installed at an upper outer side of the cylinder; and an ejector installed on an upper outer side of the cylinder.

## Claims

### Claim 1

A pore adjusting filtering apparatus comprising:
a cylinder having an inlet and a plurality of holes and in which a screw is rotatably installed to transfer suspended solids in wastewater;
an endless track coupled to an outer peripheral surface of the cylinder by an endless track pin and support;
a fiber yarn bundle support rod inserted into a middle hole of the endless track to be connected to the endless track;
a fiber yarn bundle, one end of which is fitted with and supported by the fiber yarn bundle support rod,
wherein the fiber yarn bundle surrounding the cylinder is rotated by a cylinder motor which is connected to horizontal axis of the cylinder;
a fiber yarn bundle support net supporting the fiber yarn bundle while being attached to an outer peripheral surface of the fiber yarn bundle,
wherein the closed fiber yarn bundle support net and fiber yarn bundle adjusts a pore of the fiber yarn bundle so that the contaminants are filtered through the plurality of holes of the cylinder when the fiber yarn bundle is located at a lower portion of the cylinder;
a cleaning support connecting a cleaning separator and the cylinder, the cleaning separator supporting the fiber yarn bundle support net when the fiber yarn bundle support net is separated from the fiber yarn bundle;
an ejector located between the cleaning separator and the cylinder, the ejector cleaning the contaminants by ejecting water to the fiber yarn bundle when the fiber yarn bundle and the fiber yarn bundle support net are separated from each other so that the fiber yarn bundle is located at an upper portion of the cylinder; and
a vibration unit horizontally vibrating the fiber yarn bundle while the ejector ejects water to the fiber yarn bundle,
wherein the fiber yarn bundle and the fiber yarn bundle support net are separated when the fiber yarn bundle is rotated to reach the cleaning separator.

### Claim 2 (depends on 1)

The pore adjusting filtering apparatus of claim 1, wherein the vibration unit comprises:
a spring fitted with the fiber yarn bundle support rod, wherein the spring resiliently supports the fiber yarn bundle support rod with respect to the endless track; and
a cam connected to a cam motor, wherein the cam laterally pushes and pulls the fiber yarn bundle support rod to vibrate the fiber yarn bundle,
wherein the cam is operated by the cam motor.
