TH562A - Siphon device in the drying tank - Google Patents

Abstract

Drying tank, which is heated by steam. It is used in paper making machines, equipped with a hollow cylindrical outer casing, rotating around an axis, and a built-in arc for draining the vapor condensed water from the outer arc, as well as the inner and outer duct systems. And an improved structure for the suction of condensed water with a siphon head. This siphon head has a chamber inside and a hole that matches the inner surface area of the outer casing. And installed almost close to the wall mentioned above With a wing flap at the inlet end of the siphon head It has an angled slope for the vapor condensing, and has a wall along the center line and is attached to the inner surface of the frame.
