FIG. 11 is a schematic view of a fifth embodiment of a heat treatment line for devitrified glass in accordance with the present invention; as shown in fig. 11, in which parts identical to or corresponding to those of the first embodiment are given the same reference numerals as those of the first embodiment, only the points of distinction from the first embodiment will be described below for the sake of brevity. This second embodiment differs from the first embodiment shown in fig. 1 in that:
as shown in fig. 11, 12, 13 and 14, a heat treatment line for glass ceramics of modular design, the direct cooling assembly 51 comprises:
an air inlet main pipe 511, wherein the air inlet main pipe 511 is arranged at the top of the third furnace body 52, and cooling gas flows into the air inlet main pipe;
a first air inlet branch pipe 512, wherein the first air inlet branch pipe 512 is arranged at one side of the air inlet main pipe 511 and is communicated with the air inlet main pipe 511;
a second air inlet branch pipe 513, wherein the second air inlet branch pipe 513 is arranged at the other side of the air inlet main pipe 511 relative to the first air inlet branch pipe 512, is communicated with the air inlet main pipe 511, and is positioned below the first air inlet branch pipe 512;
the air-out cooling pipes 514, a plurality of the air-out cooling pipes 514 are arranged in the direct-cooling hearth 521, the air-out cooling pipes 514 are positioned above the third conveying member 53, are equidistantly arranged along the opening direction of the direct-cooling hearth 521, and the air inlet ends of the air-out cooling pipes are communicated with the first air inlet branch pipes 512 or the second air inlet branch pipes 513;
The return air pipes 515 are arranged below the third conveying members 53, one ends of the return air pipes 515 are suspended in the direct-cooling hearth 521, and the other ends of the return air pipes penetrate through the third furnace body 52 and are arranged outside the direct-cooling hearth 521; and
the return air main 516, the return air main 516 is disposed at one side of the third furnace body 52, and is communicated with the return air main 516.
Further, the air outlet cooling pipes 514 do not have a plurality of air outlet holes 5141, the air outlet holes 5141 are disposed on one side of the air outlet cooling pipes 514 facing the third conveying member 53, and the air outlet holes 5141 are disposed in a fan-shaped distribution.
Furthermore, the air return pipe 515 is disposed at one end of the direct cooling furnace 521 and is plugged, and a plurality of air return holes 5151 are uniformly formed in the wall of the air return pipe 515 disposed in the third furnace 52, and the air return holes 5151 are formed in one side of the air return pipe 515 facing the third conveying member 53, and the air return holes 5151 are disposed in a fan-shaped configuration.
It should be noted that, the direct cooling furnace needs to cool the workpiece by introducing cooling gas into the kiln, and when the cooling gas is introduced into the direct cooling furnace, the cooling gas is first split through the air inlet main pipe 511 and then is uniformly introduced into the direct cooling furnace 521 through the first air inlet branch pipe 512 and the second air inlet branch pipe 513, so that the situation that the larger the air output of the air outlet cooling pipe 514 is near the air inlet end of the air inlet main pipe 511 is avoided.
Further, when the air-out cooling pipe 514 is provided, the air-out hole 5141 is provided facing the third conveying member 53 and is fan-shaped, so that the air-out cooling pipe 514 can cover a larger workpiece and the air-out is concentrated.
Further, the gas flowing directions of the adjacent air-out cooling pipes 514 are opposite to each other, so that the temperatures at the left side and the right side of the hearth can be uniform, and the condition that the temperature difference is generated due to the fact that the temperatures at the left side and the right side of the hearth are inconsistent is avoided.
It is particularly noted that the air-out cooling pipes 514 communicated with the first air inlet branch pipes 512 are closer to the air inlet end of the air inlet main pipe 511 than the air-out cooling pipes 514 communicated with the second air inlet branch pipes 513, so that the air-out cooling pipes 514 communicated with the second air inlet branch pipes 513 have shorter paths and more sufficient air pressure when cooling air is introduced into the direct-cooled hearth 521 by lowering the height of the second air inlet branch pipes 513.
The gas heat-exchanged with the heat in the direct-cooled furnace 521 is sent to the return air main pipe 516 via the return air pipe 515, and is output from the direct-cooled furnace 521, thereby avoiding the accumulation of hot gas in the direct-cooled furnace 521 to form high pressure.
Further, the air return hole 5151 formed in the air return pipe 515 is disposed facing the third conveying member 53, and when the air outlet cooling pipe 414 sprays cooling air to cool the workpiece, the air is directly output along the air return hole 5151 through the air return pipe 515, so that the workpiece can be cooled rapidly.
Further, the diameter of the return air hole 5151 is larger than that of the air outlet hole 5141, and the air outflow speed is larger than the air inflow speed, so that an air pressure difference can be formed in the direct cooling hearth 521, and the air flow speed is accelerated and the cooling speed is accelerated.
