[0030] In this embodiment, the heating seat includes: an upper heating seat 4 and a lower heating seat 5 that are arranged opposite to each other and connected to each other, the reaction bottle tank 7 and the gas flow channel are respectively arranged on opposite sides of the upper heating seat, and the heater is inserted into a blind hole opened in the upper heating seat. An insulating pad 6 is provided between the upper heating seat 4 and the lower heating seat 5. The insulating pad 6 can prevent the heat of the upper heating seat 4 from being transferred to the lower heating seat 5, thereby preventing damage to the platform supporting the device when the device is used. Preferably, in this embodiment, the upper heating seat 4 is made of a material with good thermal conductivity, such as copper.

[0031] In this embodiment, the reaction bottle slot 7 is arranged on the side of the heating upper seat 4 facing away from the heating lower seat 5; the reaction bottle slot 7 is used to place the reaction bottle, and the temperature of the heating upper seat 4 is adjusted to achieve the operation of heating and cooling the reaction bottle.

[0032] Furthermore, a chamfer 10 is provided on the inner side of the notch of the reaction bottle slot 7 ; the chamfer 10 is provided on the inner side of the notch of the reaction bottle slot 7 to increase the size of the notch, so as to facilitate the placement of the reaction bottle into the reaction bottle slot 7 .

[0033] Furthermore, a detection window 9 is provided on the side wall of the reaction bottle tank 7 , and a radiation sensor can be installed at the position corresponding to the detection window 9 to detect the radiation value in the reaction bottle, thereby monitoring the reaction status in the reaction bottle.

[0034] In this embodiment, the heater is disposed within the upper heating seat 4 and includes a first heating rod assembly 1 and a second heating rod assembly 2, wherein the first heating rod assembly 1 and the second heating rod assembly 2 are arranged in series. The upper heating seat 4 is provided with a temperature sensor 11 and a temperature protection switch 12. The temperature sensor 11 is used to sense the temperature of the upper heating seat 4, and the temperature protection switch 12 is connected to the heater and is used to prevent the upper heating seat 4 from overheating.

[0035] Specifically, the heating rod assembly 1 and the heating rod assembly 2 are evenly arranged in the heating upper seat 4, and heat the heating upper seat 4 by heat transfer. The temperature sensor 11 is used to detect the temperature of the heating upper seat 4 so as to regulate the temperature of the heating upper seat 4; the temperature protection switch 12 has the function of over-temperature protection. When the temperature sensor 11 detects that the temperature of the heating upper seat 4 is too high, the temperature protection switch 12 is automatically disconnected, so that the heating rod assembly 1 and the heating rod assembly 2 stop heating the heating upper seat 4.

The compressed gas passed into the gas flow channel 3 will absorb the heat in the heating upper seat 4, thereby cooling the heating upper seat 4, and then cooling the reaction bottle on the heating upper seat 4. Preferably, in this embodiment, the compressed gas passed into the gas flow channel 2 is low-temperature compressed air or compressed nitrogen; preferably, in this embodiment, the quick-plug connector 7 is an SMC brand straight-through metal quick connector, model KQB2H04-M5.

When the reaction bottle needs to be cooled, the PLC controls the solenoid valve to open, and the compressed gas in the compressed gas source is passed into the gas flow channel 3 through the quick-connect connector 8. When the compressed gas flows in the gas flow channel 3, it will take away the heat of the upper heating seat 4, and cool the reaction bottle through heat transfer.
