ABSTRACT:
The pore size controllable filter can separate and remove effectively the suspended solid and eliminate rapidly it captured by the device. The filtering materials (21) are built on the upper filtering material holder (23) and the lower filtering material holder (24) of radial type facing each other at a certain distance in the filtering tub (2), forming a filtering layer (21a). According to the direction and the degree of rotation of the upper handle (28) connected to the upper rotation axis, the filtering materials (21) come together to the center along the upper filtering material holder (23) and the lower filtering material holder (24). Then one side or both sides are twisted in opposite directions and concentrated around the perforated pipe (22) located at the central axis or restored to the original state. Accordingly, the size of the pore created between the filtering materials (21) can be adjusted, enabling to conduct filtering and washing operations at a proper level.
