Embodiment Construction

[0059] [Description of Embodiments of the Invention]

[0060] Various embodiments of the present invention will now be shown and described.

[0061] An embodiment of the present invention is a pleated filter comprising a filter substrate having folds that repeatedly form peaks and valleys, the pleated filter has a cylindrical shape, the circular The axial direction of the cylindrical shape is the ridge line direction of the folded portion, wherein the pleated filter includes an engagement reinforcement in a valley protruding to the inner side of the cylindrical shape, and the engagement reinforcement is along the fold. The direction of the ridgeline of the portion extends.

[0062] Specifically, the pleated filter has a structure in which a plurality of folded portions on the inner peripheral side of the cylindrical pleated filter each includes a joint reinforcement portion. The bonding reinforcement is a reinforcing structure that prevents damage to the folded portion of th...

Abstract

Provided is a pleated filter configured such that a filter base material having folds forming alternate ridges and troughs is formed in a cylindrical shape so that the axial direction of the cylindrical shape is aligned with the direction in which the ridges of the folds extend. Bonded reinforced sections extending in the direction in which the ridges of the folds extend are provided at the troughs which protrude toward the inside of the cylindrical shape.

Description

technical field [0001] The present invention relates to a structure of a pleated filter mainly used for filtering liquid. Specifically, the present invention relates to a pleated filter used in a treatment system for ballast water stored in a ship and for filtering a large amount of water, and an apparatus using the pleated filter. Background technique [0002] A wide variety of filters are used to separate and remove solids as contaminants from gases or liquids. Pleated filters increase the filter area by folding the filter into pleats and are also mainly used in applications involving gases, for example, in air purification systems. Patent Document 1 discloses an example of using a cylindrical pleated filter as a filtering device for removing sludge from cutting fluid of a machine tool. Regarding this device, it is described that a filter device having an excellent filter cleaning effect can be provided by spraying a liquid toward an outer surface of a cylindrical filter...
