Definitions

  • the invention provides slots defined by a plurality of profile rods being in parallelism and spaced from each other and being connected by bridging parts.
  • FIG. 1 is a plan view of a false bottom of a straining vat according to this invention
  • FIG. 2 is a section taken on line IIII of FIG. 1.
  • the false bottom illustrated in FIG. 1 consists of a plurality of sectors 10. These sectors are supported at their apexes and at their radially outer ends by the body of the cylindrical straining vat 8.
  • Each of the sectors consists of a plurality of spacedly parallel rods 12 connected to each other by radially elongated bridging members 14 in such a manner that the rods of each sector are elongated substantially at right angles to a radius drawn through the upright axis of the vat 8 and the longitudinal center point of each rod in the sector.
  • FIG. 2 shows a sectional view of the profile rods 12 and of their connection by the bridging members 14.
  • Each rod has a flat bottom face 18, an upper horizontal face 20 and two longitudinal sides 22 downwardly converging at an angle of 15 to 30, and preferably 20 to 25.
  • the height of each rod between its upper face and bottom face is 3 to 7 mm, and preferably 4 to 6 mm.
  • the rods 12 are secured to the bridging members 14 by welds 24.
  • a false bottom for a straining vat having an upright axis, said bottom being transverse to said axis and formed with a plurality of slots therethrough, the improvement which comprises:
  • said false bottom including a plurality of sectors converging toward said axis
  • each sector essentially consisting of a plurality of spacedly parallel rods and bridging members connecting said rods
  • said rods being elongated substantially at right angles to a line drawn through said axis and the longitudinal center point of each of said rods, and
  • said bridging members being elongated transversely to said rods and secured to the same, and
  • each pair of radially adjacent rods defining one of said slots therebetween.
  • each rod having a top face and two longitudinal side faces converging downwardly from said top face at an angle of 15 to 30, the height of said rod being approximately 3 to 7 millimeters.
  • said rods and bridging members consisting of stainless steel.
