Fiber disc filter having structure for preventing damage to fabric filter
The present invention relates to a fabric disc filter having a structure for preventing damage to a filter panel. In this regard, an object of the present invention is to provide a fabric disc filter having a structure for preventing damage to filter panel, being capable of preventing the filter panel attached to the filter panel from being torn or being disconnected from the filter frame in the washing process of suctioning and removing foreign matter. To accomplish this object, the present invention provides a fabric disc filter having a structure for preventing damage to filter panel, the fabric disc filter including: a rotary drum; and a plurality of filter segments arranged on an outer circumferential surface of the rotary drum, wherein each of the filter segments includes: a segment frame that is partially open so as to enable inlet of a fluid therethrough, and being configured to discharge the inlet fluid to the rotary drum; a filter frame assembled to the segment frame so as to be positioned on the fluid inlet side of the segment frame; a filter panel provided in the filter frame so as to filter foreign matter in the fluid flowing therethrough; and a rod-shaped stopper provided in the filter panel so as to distribute a load applied to the filter panel in a washing process of the filter panel and couple the filter panel to the filter frame or the segment frame.
1. A fabric disc filter having a structure for preventing damage to a filter panel, the fabric disc filter comprising:
a rotary drum; and
a plurality of filter segments arranged on an outer circumferential surface of the rotary drum,
wherein each of the plurality of filter segments includes:
a segment frame that is partially open to allow inlet of a fluid therethrough, and is configured to discharge the inlet fluid to the rotary drum;
a filter frame assembled to the segment frame and positioned on the fluid inlet side of the segment frame;
a filter panel provided in the filter frame to filter foreign matter in the fluid flowing therethrough;
a rod-shaped stopper provided in the filter panel to distribute a load applied to the filter panel in a washing process of the filter panel and couple the filter panel to the filter frame or the segment frame; and
a pocket fixedly sewn to the filter panel, the pocket including a space into which the rod-shaped stopper is fixedly inserted.
2. The fabric disc filter having the structure for preventing damage to the filter panel of claim 1 , wherein the rod-shaped stopper is provided in the filter panel to be parallel with a side portion connecting an upper end and a lower end of the segment frame to each other.
3. The fabric disc filter having the structure for preventing damage to the filter panel of claim 1 , wherein the rod-shaped stopper is provided in an end of the filter panel to be positioned inside the segment frame or inside the filter frame when the segment frame and the filter frame are assembled to each other, the rod-shaped stopper being configured to have a cross-section of a size greater than a gap between the segment frame and the filter frame.
4. The fabric disc filter having the structure for preventing damage to the filter panel of claim 1 , wherein the rod-shaped stopper is arranged to be positioned on one side in a rotational direction among four sides of the filter frame defined in a curved trapezoidal shape.
5. The fabric disc filter having the structure for preventing damage to the filter panel of claim 1 , wherein the rod-shaped stopper has a cross-section in any one of a circle, an oval, and a polygon.
