S.P. Kinney - A - Automatic Self-Cleaning Strainer - Brochure

APPLICATION Designed for continuous removal of suspended particles from all types of liquids·. Appl ications are in industrial plants using river, lake, well , or sea water for cooling, descaling , bearing lubrication, spraying, quenching, and similar purposes. Pipe-li ne sizes: 2"~42 " or larger upon application. Liquids other than water, such as chemicals, acids, white water (paper mills), sewage, and ammonia flushing liquor (coke plants) can also be effeclively strained . INSTALLATION Installation is made on Ihe discharge side of a pump or in any piping system operating under a positive pressure. The mini-mum working pressure required to effectively clean the strain-ing media is 20 psi. The strainer is compact with small face-to-face, width, and height dimensions. DESIGN The strainer consists of a cylindrical drum with a number of threaded holes containing one of many types of slraining media. The drum is supported on a rolating shall fitted with bearings and is contained in a body having a vertical back-wash slot opening adjacent 10 the drum surface. OPERATION The liquid to be strained enters the inlet connection located in the lower portion of the body and flows around the ouler sur-face of the drum. The suspended particles are relained in Ihe media pockets and the clean liquid passes through the media to the inside and bottom opening of Ihe drum-leaving the body al the oullet connection located diamelrically opposite the inlet. BACKWASH As each row of straining media passes the backwash slot, a reversal of flow occurs, flushing the suspended particles from the media pockels. This reversal of flow is caused by a pressure differential between the interior of the strainer and almosphere. The backwash flow rate is exceptionally low and will vary, depending on the amount of suspended particles in Ihe liquid . The backwash piping should discharge into an open funnel immediately aller Ihe backwash valve. AUTOMATIC BACKWASH CONTROL In lieu of a manually operated valve on Ihe backwash outlet line, an automatic control can be furnished to permit inter-mittenl backflushing. Th is control consists of a motor or pneumatic cyl inder operated ball valve, actuated by a timer or a pressure differential swilch (or both). ADJUSTMENT AND SHEARING ACTION The clearance belween the backwash slot and the drum is equal to or smaller Ihan the opening presented in Ihe media-and can be adjusled easily by two locknuts on the Ihreaded part of the top section of the shaft. The backwash slot con-tains a knife-like edge which enables the strainer 10 shear debris such as wood, shells, fish, and olher suspended male-rials which may exlend beyond the surface of Ihe drum- with no resultant damage to the drum, straining media, or drive unit. INSPECTION The Kinney strainer el iminates troublesome disassembly by providing an opening in the side of the strainer body. To inspect the straining media, simply remove the cover and manually rotate the drum. As each row of media passes the inspection opening , easy access to the media is achieved-optional on sizes 2", 3" , 4" and 6".
