Problems solved by technology
[0002] At present, in the related technology, the heating chamber and the working chamber of the heat treatment furnace, the pressure in the heating chamber is the same as the pressure in the working chamber at this time; when the gas is heated in the heating chamber of the heat treatment furnace, it flows into the working chamber and At the same time, the gas in the working chamber flows into the heating chamber, because the gas expands after heating, so the pressure in the working chamber is higher than the pressure in the heating chamber; when the gas in the heating chamber is at full load, the working chamber The gas in the heat treatment furnace will expand outward due to excessive pressure, which will not only cause heat loss in the heat treatment furnace, but also cause deformation of the furnace body, resulting in potential safety hazards

The invention provides a heat treatment furnace with stable pressure. The heat treatment furnace with stable pressure comprises a furnace body and a heating assembly; the furnace body is provided witha working cavity, the side wall of the furnace body is provided with an air inlet and an air outlet, the air inlet is communicated with the working cavity, and the air outlet is communicated with theworking cavity; the heating assembly comprises a shell, an air return part and an air supply part, the shell is provided with a heating cavity, one end of the air supply part is communicated with theheating cavity, the other end is communicated with the air inlet, one end of the air return part is communicated with the heating cavity, and the other end is communicated with the air outlet; and the air supply amount of the air supply part is smaller than the air return amount of the air return part. Since the air supply amount of the air supply part is smaller than the air return amount of theair return part, the micro-negative-pressure control for the working cavity is realized, the gas in the working cavity is prevented from being expanded outwardly after being heated, the heat loss isreduced, the deformation of the furnace body caused by the expansion of the heated gas can also be avoided, and the application safety of the heat treatment furnace can be improved.
Description
technical field [0001] The invention relates to the technical field of heat treatment, in particular to a pressure-stabilized heat treatment furnace. Background technique [0002] At present, in the related technology, the heating chamber and the working chamber of the heat treatment furnace, the pressure in the heating chamber is the same as the pressure in the working chamber at this time; when the gas is heated in the heating chamber of the heat treatment furnace, it flows into the working chamber and At the same time, the gas in the working chamber flows into the heating chamber, because the gas expands after heating, so the pressure in the working chamber is higher than the pressure in the heating chamber; when the gas in the heating chamber is at full load, the working chamber The gas in the furnace will expand outward due to excessive pressure, which will not only cause heat loss in the heat treatment furnace, but also cause deformation of the furnace body, resulting ...
