Problems solved by technology

However, the above-mentioned filter has a disadvantage, because the filter material located near the circular plate is not pressurized, and the movable circular plate moves in the direction of the fixed circular plate to carry out pressurization operation, so that the filter material is not subjected to tension
In this case the filter area is too small compared to the size of the filter drum (2)
In addition, pressurized filtration is not possible due to the movement of the shaft through the filter barrel (2)

Embodiment Construction

[0027] figure 2is a view of a one-stage rotary adjustable aperture filter 120 according to an embodiment of the present invention. As shown in the figure, a raw water delivery unit (1), a filter layer (21a), and a treated water discharge member (3) are installed from the circumferential direction to the central direction of the filter barrel (2). In the upper flange (13) of the filter bucket (2), a hole is formed into which the upper shaft (25) is inserted, and a hole engaged with the upper shaft sealing part (26) is formed so that water does not flow through the upper The gap between the shaft (25) and the upper flange (13), and a welded pipe, is used to engage the safety valve (14) and take pressure measurement. The perforated pipe (22) passes through the lower flange (33) of the filter tub (2) and is welded thereto, and a welded pipe is used to connect the washing air delivery pipe (34). One end of the upper rotating shaft (25) is connected with the upper handle (28), an...

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.

Description

field of invention [0001] The present invention relates to a filter with adjustable pore size, which can remove suspended solids in water, more particularly, relates to a filter with adjustable pore size, which can pass filter materials with good expansion and contraction characteristics ( 21) form the filter layer (21a) by being connected with the radial filter material support (23) and the lower filter material support (24) that are arranged oppositely at a certain interval, so that, by making the upper filter material support (23) and the lower filter The filter material (21) connected to the material support (24) is wound on the perforated tube (22) located on the central axis according to the rotation direction and degree of the rotating shaft, and receives a certain tension, and along the upper filter material support (23) and the central direction of the lower filter material support (24), the size of the pores can be reduced; and by making the filter material (21) retu...
