A braided strainer for a draw line, and method of forming same. The strainer comprises a frame in the form of a pair of spaced planar plates, one being a solid end plate and the other having a control aperture. A plurality of spaced, parallel rods of similar length are positioned near the peripheries of the plates and secured and extending between the plates. A plurality of cylindrical walls of braided strands of strainer medium, are provided, the braided cylindrical walls having similarly spaced rod-receiving holes extending longitudinally in spaced fashion through the strands of strainer medium. These walls are contiguously stacked on the plates to extend between them. The plate having the central aperture permits flow of fluid drawn through the cylindrical walls during operation of the strainer. That plate has associated with it a connector to releasably secure the strainer to a mating connector on a free end of the draw line.
A method of forming a braided strainer for a draw line, the method comprising the steps of stacking a plurality of braided strainer walls formed of braided strands of strainer medium and having similarly spaced rod-receiving holes extending linearly longitudinally in spaced fashion through the walls, onto parallel, upstanding rods of similar length, the rods secured to a base plate, by passing the rods through corresponding rod-receiving holes in the walls so that the braided walls are stacked on the plate up to free ends of the rods in contiguous fashion, and securing a retainer plate on the free ends of the rods to secure the braided walls in stacked position on the rods.
A method of forming a braided strainer or a draw line, the method comprising forming a circular plate having a plurality of parallel, upstanding rods of similar length secured in regular, upstanding, circular fashion about the plate, and embedding a length of braided strands of strainer medium, in spiral contiguous fashion on the rods in contiguous fashion to form a uniform cylindrical strainer wall over the length of the rods and securing a retainer plate on free ends of the rods adjacent a portion of the length of strainer medium.
A braided strainer for a draw line, the strainer comprising a frame in the form of a pair of spaced planar plates, one a solid end plate and the other having a central aperture, and a plurality of spaced, parallel rods of similar length positioned near the peripheries of the plates and secured and extending between the plates, and a plurality of walls of braided strands of strainer medium, the braided walls having similarly spaced rod-receiving holes extending longitudinally in spaced fashion through the strands of filter medium, contiguously stacked on the plates to extend between them, the plate having the central aperture permitting flow of fluid drawn through the walls during operation of the strainer into the draw line, that plate having associated with it a connector to releasably secure the strainer to a mating connector on a free end of the draw line.
