[0049] A lifting door 10 is installed between the hydrolysis device 5 and the drying device 6, so that the drying device 6 is isolated from other workstations to avoid contaminating other workstations.

[0050] In some embodiments, as Figure 7 shown, the specimen placement device 8 includes a placement tube body 81. An annular structure is formed at the upper part of the placement tube body 81. A threaded tube 82 is sleeved on the outer periphery of the annular structure of the placement tube body 81. The inner side of the threaded tube 82 has an inner ring body 823 capable of supporting the annular structure of the placement tube body 81. The threaded tube 82 is fitted with a bolt 83. A gasket 84 is installed between the bolt 83 and the placement tube body 81. By tightening the bolt 83, the rod part of the bolt 83 abuts against the gasket 84, so as to achieve a sealing effect. By twisting the head of the bolt 83, the rod of the bolt 83 is moved out of the inside of the threaded tube 82, so that the placement tube body 81 can be moved out of the threaded tube 82 and the specimen can be taken out. The outer shape of the threaded tube 82 is a regular hexagon structure.

[0051] In some embodiments, the liquid nitrogen freezing device 1 includes a rotating table 101 and three liquid nitrogen cups 102. The rotating table 101 includes a rotatable bearing plate 103 for placing the liquid nitrogen cups. The bearing plate 103 is fitted with a stepping motor 104 capable of controlling the rotation angle of the bearing plate. A pillar 105 is provided in the middle of the bearing plate. A bearing rod 106 for placing the specimen placement device 8 is provided at the top of the pillar 105. The end of the bearing rod 106 is located above the liquid nitrogen cup. Specifically, the specimen placement device 8 is placed on the bearing rod, just making the placement tube body 81 located in the liquid nitrogen cup, and the specimen is frozen. After the freezing is completed, the specimen placement device 8 is removed from the liquid nitrogen cup by the grasping device 2 and sent to the specimen opening device 3.

The rotation of the stepping motor 325 drives the rotation of the lead screw 324. The rotation of the lead screw 324 drives the movable clamping part 322 to move away from or close to the fixed clamping part 323. A jacking cylinder 326 is further provided below the fixed clamping part 323 and the movable clamping part 322 for jacking out the placement tube 81.

An expansion rod 312 is installed on the hanging rack 311. A servo motor 313 is installed below the expansion rod 312 through a bearing platform 315. A cap screwing part 314 capable of sleeving on the bolt 83 is installed at the end of the servo motor 313.

[0056] The specimen placement device 8 is transferred between the fixed clamping part 323 and the movable clamping part 322 by controlling the grasping device 2, and the movable clamping part 322 is controlled to clamp the threaded tube 82 part of the specimen placement device 8. By controlling the elongation of the expansion rod 312 of the lid opening device 31, the bearing platform 315 moves downward, so that the cap screwing part 314 is sleeved on the bolt 83. The servo motor 313 is controlled to rotate by a set angle, so that the bolt 83 is taken out from the threaded tube 82, and the bearing platform 315 returns to its position. The bolt 83 is moved away by controlling the grasping device 2. Then, the jacking cylinder 326 is controlled to jack out a part of the placement tube 81 from the threaded tube 82. Then, the grasping device 2 is controlled to place the placement tube 81 into the crucible 46. The jacking cylinder 326 is controlled to continue to jack up the threaded tube 82. Then, the grasping device 2 is controlled to clamp the threaded tube 82. At the same time, the movable clamping part 322 is controlled to loosen the threaded tube 82. The grasping device 2 moves the threaded tube 82 to a set position, and the jacking cylinder 326 returns to its position. Multiple operations can complete the transfer of multiple specimen placement devices 8.

[0057] In some embodiments, a fixed placement device 12 is further included. The fixed placement device 12 includes a plurality of receiving cups 121.

A strip-shaped clamp pan 46 for installing the pipe body 81 is installed on the support table 45, and the number of the strip-shaped clamp pans 46 is six. Specifically, the height of the support table 45 is adjusted by the cylinder 44 to facilitate cooperation with the hydrolysis device 5 and the drying device 6.

[0059] In some embodiments, the hydrolysis device 5 is arranged above the linear guide rail module. The hydrolysis device 5 includes a box body 51 with an opening at the bottom and an opening and closing door 52 provided thereon. The box body 51 is connected with a cold air blower 11 capable of making the temperature between 0°C and 20°C; a first exhaust port 53 is provided at the top of the box body 51, and an air extraction device is installed at the first exhaust port to form a micro-negative pressure inside the box body 51. Specifically, the hydrolysis device 5 is arranged above the linear guide rail module so that the specimen tray device 4 can be moved to the lower part of the hydrolysis device 5 through the linear guide rail module 7. By controlling the extension of the cylinder 44, the support table 45 and the clamp pan 46 thereon enter the box body 51 from the opening at the bottom of the box body 51 for hydrolysis. In the present invention, six specimens can be hydrolyzed in sequence. By introducing cold air at a set temperature through the provided cold air blower 11, the hydrolysis temperature is maintained between 0°C and 20°C, and the temperature can be adjusted according to needs to maintain the constant temperature and low temperature of the hydrolysis temperature.

[0060] In some embodiments, the drying device 6 is arranged above the linear guide rail module. The drying device 6 includes a stainless steel shell 61 with an opening at the bottom and a quartz gas collection hood 62 arranged inside the shell 61. A heat insulation structure 64 and a heating structure are provided on the inner wall of the shell. The inner walls of the heat insulation structure 64 and the heating structure are made of Monel alloy. The shell 61 is also connected with a steam generator 13; a second exhaust port 63 connected to the outside is provided at the top of the collection hood 62, and an air extraction device is installed at the second exhaust port 63 to form a micro-negative pressure inside the shell 61. The drying device 6 can be a muffle furnace.

[0061] Specifically, after the hydrolysis process is completed, the lifting door 10 is controlled to rise and open, and the linear guide rail module 7 is controlled to move the specimen tray device 4 below the drying device 6. By controlling the elongation of the cylinder 44, the support table 45 and the crucible 46 thereon are extended from the bottom of the housing 61 into the housing 61. Predrying is carried out at a set temperature to evaporate most of the moisture, and then the temperature is raised for final drying. The drying temperature can be up to 1000 °C. The Monel alloy provided on the inner wall can prevent acid gas corrosion. The steam generator 13 provided can continuously introduce steam. The steam is used to dilute the hydrogen fluoride gas generated during sample drying to prevent the generation of high-concentration hydrogen fluoride gas. A quartz observation window can also be provided on the housing 61, and a camera can be installed to observe the drying situation in the furnace in real time. The present invention forms a micro-negative pressure to prevent gas from flowing into other processes.
