DEBRIS FILTER
Document Type and Number:
WIPO Patent Application WO/2012/073461
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a debris filter which causes small pressure loss of flowing cooling water and which can capture foreign matter contained in the cooling water. A debris filter is provided with: bent plates having the same shape; first grid plates having the same shape; and second grid plates having the same shape. The first grid plates and the second grid plates are strip-shaped. Each of the bent plates consists of a strip-shaped first sloped plate and a strip-shaped second sloped plate, the second sloped plate having a longitudinal side which extends in the longitudinal direction of the corresponding first sloped plate and which is shared with the first sloped plate. First longitudinal sides of the parallelly arranged bent plates, the first longitudinal sides being located on the side opposite the shared longitudinal sides, intersect the first grid plates to affix the bent plates and the first grid plates to each other. Second longitudinal sides of the bent plates, the second longitudinal sides being located on the side opposite the shared longitudinal sides, intersect the second grid plates to affix the bent plates and the second grid plates to each other. Longitudinal sides of the first grid plates affixed to the bent plates, the longitudinal sides facing the second grid plates, and longitudinal sides of the second grid plates affixed to the bent plate, the longitudinal sides facing the first grid plates, are not in contact with each other.
