Description

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a backwashing suction device for a fibrous filter, and a fibrous filter using the same. BACKGROUND OF THE INVENTION [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reverse-cleaning suction device and a fibrous filter using the reverse-cleaning suction device, and more particularly, The filtration performance of the disk-type filter is improved by preventing the fibers from being pressed by the back-washing suction device while the wastewater is filtered through the disk-shaped filter, and the energy consumption can be reduced as well as the life- will be.

Generally, a fibrous filter is a filter that has fibers (tungsten) on the surface of a disc-shaped filter to filter foreign materials into the filter while the wastewater or the like passes through the disc filter to filter the wastewater.

Patent Document 1 discloses a disk-shaped fibrous filtering apparatus. This fibrous filter apparatus is a liquid filtration apparatus in which a filter cloth is positioned on a flow path of a liquid to be filtered, the filter cloth having a fleece on the side exposed to the flow, and the length, strength and density of the fleece A liquid filtration device capable of forming a dip filter having a plurality of meandering flow channels that are flattened by a flow to form an angle, the liquid filtration device comprising: A suction bar having a suction slit for sucking a backwash flow through the filter cloth at a flow rate at which the filter bag is calibrated, and means for relatively moving the suction bar and the filter cloth in a moving direction parallel to the filter cloth.

The suction bar has at least a surface directed toward the filter cloth on the side of the suction slit positioned forward relative to the relative movement and the surface is located with a narrow gap facing the filter cloth so that a mechanical action is applied to the fleece Prevent the hair fleeces from being straightened.

Particularly, in such a fibrous filter apparatus, as the disk-shaped filter rotates with the suction bar fixed, the linear calibration is delayed before the fleece reaches the suction slit by the surface of the suction bar, and when the suction slit reaches the suction slit, So that the foreign substances which have been collected in the filtration process by the fleece can be sucked in.

However, such a conventional fibrous filter apparatus has the following problems.

1) The suction bar is always in contact with the surface of the disk-shaped filter to some extent. This is because when the fibers of the disc-shaped filter abutting the suction bar are not backwashed, for example, the wastewater is continuously pressed even during filtration, so that the filtration action is not smooth in the pressed fiber portion, There is a problem that the filtration efficiency is lowered.

2) In particular, the pressing phenomenon of such fibers occurs unnecessarily when the suction bar is not used. That is, the disk type filter is mounted so that a plurality of the disk type filters can be rotated by one rotation axis according to the size of the filtration facility, and when it is determined that the foreign matter needs to be removed, the disk type filter is rotated Thereby removing foreign matter from the surface. In this case, since most of the disc type filters are removed at the same time without removing the foreign substances at the same time, the disc type filter, which does not need to remove the foreign substances, rotates together with the foreign substances, .

3) Due to the pushing action of the fiber by the suction bar, the coagulated foreign matter collected between the fibers is finely crushed and can pass through the surface of the disk type filter. This may cause a serious problem that harmful substances contained in the wastewater, for example, harmful substances such as phosphorus (P), are passed through the disk filter and contained in the filtered water.

4) Since all the suction bars are kept in contact with the disk-shaped filter at all times, friction between the suction bar and the disk-shaped filter is unnecessarily increased, so that the surface of the disk-type filter, that is, the wear of the fiber is promoted, , Additional energy is required to rotate the disk filter. As a result, there has been a problem in that the size of the power transmission device of the filtration device is increased.
