More specifically, the water circulation mechanism 4 is a water pump, and is communicated with the circulating water port 101 through a pipeline.

[0041] Under the above design, cooling water enters the upper chamber 1a of the water tank 1 through the circulating water inlet 101, and then enters the lower chamber 1b of the water tank 1 through the return port 102, and the cooling water on the side of the return port 102 of the lower chamber 1b is pumped into the upper chamber 1a by the water circulation mechanism 4. The circulation path is as follows: Figure 2 Compared with the case where the water tank 1 is not divided, the design of the present application helps to make the temperature of the cooling water in the water tank 1 more uniform, which has a significant effect on the cooling speed. Preferably, the circulating water inlet 101 is located at the bottom of the upper chamber 1a. This preference is conducive to the cooling water with the increased temperature of the upper chamber 1a being pressed into the lower chamber 1b for circulation.

[0043] In this embodiment, the clamping mechanism 2 includes a mounting frame 21 disposed on the lifting mechanism 3, and a positioning module 22 disposed on the mounting frame 21; the mounting frame 21 is provided with two mounting positions 210 for placing the ampoule bottle 100; the positioning module 22 includes a positioning column 221 disposed on the mounting frame 21 and a pressing block 222 slidably connected to the positioning column 221; the pressing block 222 is provided with a positioning hole 2221 matching the shape and size of the bottle mouth of the ampoule bottle 100 and is used to fix the ampoule bottle 100 on the mounting position 210. Preferably, the mounting frame 21 is hollow at the bottom of the mounting position 210.

[0044] In actual application, the staff puts the ampoule bottle 100 into the installation position 210, and then aligns the positioning hole 2221 of the pressing block 222 with the bottle mouth of the ampoule bottle 100, and drives the pressing block 222 to descend along the positioning column 221, so as to fix the ampoule bottle 100 and prevent the ampoule bottle 100 from shaking during the cooling process and causing a defective glass rod.

[0045] As a preferred embodiment of the present invention, the mounting position 210 is composed of a pair of limit blocks 211 disposed on both sides of the mounting frame 21 and a clamping block 212 detachably connected to the limit blocks 211; the clamping block 212 is provided with a through hole matching the shape and size of the ampoule bottle 100 and is used to place the ampoule bottle 100. Under the above preferred embodiment, the present invention can also be applied to ampoule bottles 100 of various sizes, so as to prepare ampoule bottles 100 of different sizes.

[0046] In order to facilitate the staff to clean the bottom of the water tank 1, the guide plate 11 includes a fixed block 111 arranged in the water tank 1, and a movable block 112 hinged to the fixed block 111; the notch is arranged in the movable block 112; and the movable block 112 is provided with a handle 113. Of course, this embodiment only provides a preferred solution, and in other embodiments, the guide plate 11 can also be an immovable steel plate.

[0047] In this embodiment, specifically, the lifting mechanism 3 includes a first linear guide rail and a first slider 31 thereof, a second linear guide rail and a second slider 32 thereof, a third linear guide rail and a third slider 33 thereof, and a first power module 34 arranged on the water tank 1; the clamping mechanism 2 is respectively connected to the first slider, the second slider and the third slider; the first power module 34 is used to drive the first slider, the second slider and the third slider to move vertically synchronously.

[0048] More specifically, the first linear guide is arranged outside the water tank 1 and in the middle, and the first power module 34 directly drives the first slider to rise and fall vertically. Preferably, in this embodiment, the first power module 34 is a motor screw sliding pair. The second linear guide and the third linear guide are located in the water tank 1 and are arranged on both sides of the first linear guide respectively; the rear, left and right sides of the mounting frame 21 of the clamping mechanism 2 are fixed on the first slider, the second slider and the third slider respectively.

[0049] The lifting mechanism 3 is designed to enable the clamping mechanism 2 to be lifted up and down more stably, thereby reducing the shaking of the ampoule bottle 100 caused by mechanical movement.

[0050] In this embodiment, a water outlet 12 for replacing cooling water is provided at the bottom of the water tank 1. When the temperature of the cooling water rises to a temperature that does not meet the cooling requirements, the cooling water in the water tank 1 can be completely discharged by opening the water outlet 12. In other embodiments, the water tank 1 may also be provided with a water inlet for replenishing cooling water. In addition, in order to facilitate the movement of the device, casters 13 are also provided at the bottom of the water tank 1 for easy movement.

[0051] In this embodiment, a cover plate 14 is provided on the top of the water tank 1. Preferably, a transparent glass is provided on the cover plate 14 as an observation window. The cover plate 14 is slidably connected to the water tank 1. In addition, the cover plate 14 remains closed during the cooling process. When the staff needs to replace the ampoule bottle 100, they only need to drive the cover plate 14 to move to expose the installation position 210 for replacement.

[0052] Example 2

[0053] refer to Figure 5 , which is basically the same as the embodiment 1, except that: this embodiment further includes a temperature regulating mechanism 5, and the temperature regulating mechanism 5 includes a heater 51 for heating cooling water and a thermocouple 52 for detecting the temperature of cooling water. In actual use, the heater 51 and the thermocouple 52 are both arranged in the water tank 1, and the heater 51 is controlled and heated by an external electric control box. Its function is to adjust the initial temperature of the cooling water in the water tank 1 to between 35 and 40°C.

[0054] Example 3

[0055] In addition, the present application also provides a chalcogenide glass cooling method, based on the chalcogenide glass cooling device described in Example 2, the chalcogenide glass in this embodiment is As 2 Se 3 Chalcogenide glass, firstly mix As powder and Se powder in a certain ratio and then put them into a high temperature resistant ampoule 100, and evacuate the ampoule 100 to 1*10 -3 Pa or less, the ampoule 100 is sealed, and then the ampoule 100 is placed in a rocking furnace and heated to 900°C at a heating rate of 5°C / min, so that the chalcogenide glass crystals in the ampoule 100 become a molten state (i.e., liquid state), and rocked for 10 hours to fully shake the chalcogenide glass in the ampoule 100. When the chalcogenide glass in the ampoule 100 has completely become a uniform state, the ampoule 100 is taken out of the rocking furnace and begins to cool. The cooling includes the following steps:

[0056] Step 1: Place the ampoule 100 containing liquid chalcogenide glass into the chalcogenide glass cooling device and fix it by the clamping mechanism 2; specifically, place the ampoule 100 into the through hole of the clamping block 212, then align the positioning hole 2221 of the pressing block 222 with the bottle mouth of the ampoule 100 and drive the pressing block 222 to descend along the positioning column 221, thereby fixing the ampoule 100 and closing the cover 14.

[0057] Step 2: The lifting mechanism 3 drives the clamping mechanism 2 to descend vertically, and the lower part of the ampoule bottle 100 is immersed in cooling water and cooled for 5 minutes; it should be noted that, since generally only about one-third of the volume of the ampoule bottle 100 is filled with chalcogenide glass, in actual application, the lifting distance and the immersion depth are adaptively adjusted.

[0058] Step 3: The water circulation mechanism 4 continuously circulates the cooling water in the water tank 1; specifically, the cooling water enters the upper chamber 1a of the water tank 1 through the circulating water inlet 101, and then enters the lower chamber 1b of the water tank 1 through the reflux port 102, and the water circulation mechanism 4 draws the cooling water on one side of the reflux port 102 of the lower chamber 1b into the upper chamber 1a.

[0059] Step 4: The lifting mechanism 3 drives the clamping mechanism 2 to rise vertically to take out the ampoule bottle 100;

[0060] The ampoule bottle 100 is columnar, and has a columnar bottle mouth at the upper end;

[0061] Before step 3, the temperature of the cooling water needs to be adjusted by the temperature regulating mechanism 4. In this embodiment, the temperature of the cooling water is 35°C.

[0062] The cooling method has the advantages of preventing the ampoule 100 from breaking due to excessive cooling and improving the quality of the finished product. The surface of the chalcogenide glass rod prepared by the method is smoother and has no stripes.

[0063] Example 4

[0064] It is basically the same as Example 3, except that the temperature of the cooling water is 40°C.

[0065] Comparative Example 1

[0066] refer to Figure 6 The same chalcogenide glass as in Example 3 is selected, As powder and Se powder are first mixed in a certain ratio and then put into a high temperature resistant ampoule 100, and the ampoule 100 is evacuated to 1*10 -3Pa, seal the ampoule 100, then put the ampoule 100 into a rocking furnace and heat it to 900°C at a heating rate of 5°C / min to make the chalcogenide glass crystals in the ampoule 100 become a molten state (i.e., liquid), and rock it for 10 hours. When the chalcogenide glass in the ampoule 100 has completely become a uniform state, take out the ampoule 100 from the rocking furnace and fix it in a cooling bellows, then introduce natural wind at a wind pressure of 30KPa and a wind speed of 100m / s to cool the ampoule 100 until the surface temperature of the ampoule 100 drops to 100°C.

[0067] Comparative Example 2

[0068] refer to Figure 7 The same chalcogenide glass as in Example 3 is selected, As powder and Se powder are first mixed in a certain ratio and then put into a high temperature resistant ampoule 100, and the ampoule 100 is evacuated to 1*10 -3 Pa, seal the ampoule 100, then put the ampoule 100 into a rocking furnace and heat it to 900°C at a heating rate of 5°C / min to turn the chalcogenide glass crystals in the ampoule 100 into a molten state (i.e., liquid state), and rock it for 10 hours to fully shake the chalcogenide glass in the ampoule 100 evenly. When the chalcogenide glass in the ampoule 100 has become completely uniform, take out the ampoule 100 from the rocking furnace, and then directly put the ampoule into cooling water at 35°C and cool it for 5 minutes.

[0069] test:

[0070] Ten groups of chalcogenide glass rods were produced respectively by the methods of Example 3, Example 4, Comparative Example 1 and Comparative Example 2.

[0071] Results and analysis:

[0072] The ten groups of production in Examples 3 and 4 all obtained chalcogenide glass rods with uniform texture and smooth surface, and the subsequent machining production requirements were met after annealing treatment, and the cooling efficiency was high. Comparing Example 3 and Example 4, there was no obvious difference except for the cooling efficiency. After cooling for 5 minutes in Example 3, the surface temperature of the ampoule can be reduced to about 100°C, while it takes about 7 minutes for the surface temperature of the ampoule in Example 4 to be reduced to about 100°C.

[0073] Six of the ten groups produced in Comparative Example 1 obtained chalcogenide glass rods with uniform texture and smooth surface. The remaining four groups had surface defects of varying degrees. The reason is presumed to be that the cooling rate of the air cooling in Comparative Example 1 is slightly slower than the cooling rate of the water cooling in Example 2. During cooling, the surface temperature drops and the volume shrinks, but the center layer still maintains a relatively high temperature and the volume has not changed in time. The glass surface is affected by stress, resulting in cracks on the surface. Figure 6 .

[0074] In the ten groups of production in Comparative Example 2, no chalcogenide glass rod with uniform texture and smooth surface was obtained. It is speculated that the reason is that the ampoule bottle is not effectively fixed during the cooling process, the liquid glass shakes greatly in the ampoule bottle, and stripes appear on the surface after cooling and solidification. Figure 7 .

[0075] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
