DESCRIPTION:
BRIEF SUMMARY
The invention relates to an improved machine for heating an article or product by condensing vapour thereon.
From French Pat. No. 2,243,045 there is known a machine for heating an article at an elevated temperature, for example with a view to subjecting it to welding or brazing operations, by condensing thereon the vapour of a liquid with a high boiling point, which comprises an enclosure open to the atmosphere and adapted to contain a primary liquid having a boiling point which is at least equal to the said elevated temperature; means of heating which are close to the lower end of the enclosure and adapted to boil the primary liquid to produce primary vapour, primary means for condensation at a first height above the bottom of the enclosure and adapted to condense the primary vapour to primary liquid at the first height; primary means for collecting condensate which are associated with the primary means for condensation and adapted to collect the condensed primary vapour originating therefrom; a first conduit forming communication between the primary means for collecting condensate and the lower part of the enclosure and adapted to convey condensed primary vapour from the primary means for collecting condensate towards the lower part of the enclosure; means for establishing a mass of secondary vapour in the enclosure above the primary vapour; secondary means for condensation at a second height above the first height and adapted to condense the secondary vapour to secondary liquid at the second height, secondary means of collecting condensate which are associated with the secondary means of condensation and adapted to collect the secondary condensed vapour originating therefrom; and a second conduit providing a communication between the secondary means of collecting condensate and the primary means of collecting condensate, and adapted to convey the condensed secondary vapour from the secondary means of collecting condensate to the primary means of collecting condensate.
The operation of this machine is satisfactory. Nevertheless, ever-increasing requirements of industrialists mean that there is a need for an improved machine.
The invention consequently proposes to provide a machine for "in-line"-type heating of an article or product by condensing vapour thereon, which, as a result of its novel design, makes it possible in particular:
to suppress the heat changes inherent in the machines available on the market at the present time by avoiding or minimising as much as possible the mixing of vapour of the primary and secondary liquids in the enclosure for heating the articles;
to control the heat cycle accurately;
to employ mixtures of liquids with different boiling points;
optionally, to clean the product or the article as efficiently as possible after a treatment.
The invention relates to an improved machine for heating an article or product at an elevated temperature by condensing vapour thereon, which comprises:
a chamber for heating the article or product to be heated, this chamber being adapted to receive a vapour of a primary liquid having a boiling point which is at least equal to the said elevated temperature;
at least one passage opening into the said chamber for the entry and removal of the said article or product to be heated;
means of moving the article or product to be heated from the entry to the exit of the machine;
means of heating which are adapted to heat to boiling a primary liquid contained in a boiler and to produce primary vapour intended to be fed into the said chamber;
means for establishing in the said passage a body of vapour of a secondary liquid having a boiling point which is lower than that of the primary liquid, the said body completely filling a section of the said passage;
primary means of condensation which are adapted to condense primary vapour to primary liquid;
means of collecting primary condensate which are adapted to collect the condensed primary vapour and to redirect it to the boiler;
secondary means of condensation adapted to condense the secondary vapour to second
