Example Embodiment

[0027] Example 1: Such as figure 1 with figure 2 As shown, the combined automatic air drying balance device for sample preparation of the present invention includes more than one drying balance assembly and a control box 7. Each drying balance assembly is arranged side by side and separated by a central partition 16 The air balance box 1 and the heating and drying box 14 are relatively closed. The heating and drying box 14 is equipped with a heating plate 12 and a measurement and control element 3, which has the function of heating/heating and constant temperature, and the temperature is controllable; each group of heating and drying boxes 14 is a method of heating and temperature control using a separate heating plate 12, and the measurement and control element 3 is used for temperature measurement and monitoring. The heating and drying box 14 is provided with an air inlet 13 and an air outlet 15. The air inlet 13 is located at the bottom of the box body, and the air outlet 15 is located on the top of the box body; the air entering from the air inlet 13 passes through the heating plate 12 to draw the hot air upward from the breathable compartment 8 It is brought into the upper heating chamber and the water vapor is taken out from the air outlet 15 on the top. There are several stakeout sections in the heating and drying oven 14 for placing sample pans 6, each of which is equipped with a first pattern detection component 5, which is used to detect whether the corresponding stakeout section has The sample pan 6 is put in. When the user puts the sample pan 6 into the heating and drying oven 14, when it is detected that the sample pan 6 is put into the corresponding position, the heating and countdown are automatically started. After the set heating time is reached, the control box 7 issues an instruction through an alarm component (buzzer or indicator light) to remind the user which sample tray 6 has finished heating and drying, and sampling can be done.
[0028] The air balance box 1 is in a state of natural ventilation. There are several stakeout sections in the air balance box 1 for placing the sample tray 6. Each stakeout section is provided with a second sample tray detection component 21, a second sample tray detection component 21 is used to detect whether there is a sample pan 6 in the corresponding lofting section. When the sample pan 6 is placed in the air balance box 1, and the second sample pan detection component 21 detects that the sample pan has been put in, the system automatically counts down. When the set balance time is reached, the control box 7 issues an instruction through an alarm component (buzzer or indicator light) to remind the user which sample tray 6 has finished air balance and can take samples.
[0029] In this embodiment, the heating and drying box 14 and the air balance box 1 have functions such as heating time and balance time setting, increase/decrease timing display, etc., and the operation of the entire system can be controlled by the control box 7 according to the set temperature and time. The control box 7 is provided with a display area 11 and an operation area 10.
[0030] The drying balance device of the present invention adopts a combined working mode, can realize any combination of single or multiple groups of drying balance components, is flexible and diverse, and can meet the needs of different users. The air balance box 1 can be used independently, can automatically time and prompt, to meet the user's requirements for only air balance processing. Single or multiple groups of drying balance components are uniformly controlled by the control box 7, and man-machine dialogue can be realized through the operation area 10 for parameter setting; the status of each sample tray 6 can also be displayed by setting the display area 11. It is convenient for users to monitor the sample tray 6.
[0031] As a preferred embodiment, this embodiment further includes a table 9 for placing a number of drying balance components and a control box 7 to facilitate user management and operation.

Example Embodiment

[0032] Example 2: Such as image 3 with Figure 4 As shown, the structure of this embodiment is basically the same as that of Embodiment 1, and the difference is that: this embodiment is further used to move the sample pan 6 from the heating and drying oven 14 to the sample transfer assembly 4 of the air balance box 1. When the heating and drying time of the sample pan 6 is up, the qualified sample pan 6 can be automatically pushed into the air balance box 1 through the sample transfer assembly 4.
[0033] In this embodiment, a movable door 17 is hinged on the central partition 16. When the sample tray 6 moves under the drive of the sample transfer assembly 4, the sample tray 6 can push the movable door 17 to turn over. After the sample tray 6 passes, the movable door 17 and self-closing by its own weight. It can be understood that the movable door 17 can also be driven by electric, pneumatic, magnetic, hydraulic and other methods or mechanisms, and the control box 7 controls its automatic opening and closing. After the sample pan 6 is moved to the air balance box 1, through the real-time detection of the second sample pan detection component 21, the system automatically starts the balance countdown. When the set balance time is reached, the control box 7 issues an instruction through an alarm component (buzzer or indicator light) to remind the user which sample tray 6 has finished air balance and can take samples.
[0034] If the user fails to remove the sample pan 6 that has been balanced in the air balance box 1 in time, and the stakeout part in the air balance box 1 is full, the control box 7 will control it not to perform automatic sample pushing and stop heating at the same time. Continue to push the sample when there is a space in the air balance box 1.
[0035] In this embodiment, the purpose of the sample transfer assembly 4 is only to automatically move the sample pan 6 from the heating and drying oven 14 to the air balance box 1. The horizontal push form of the sample pan 6 shown in this embodiment can be used, and other implementations In the example, other methods such as robotic grasping and belt translation can also be used to transfer the sample tray, which will not be repeated here.

Example Embodiment

[0036] Example 3: Such as Figure 5 As shown, the structure of this embodiment is basically the same as that of Embodiment 2. The difference is that this embodiment is further provided with a dehumidification assembly 2 in series between the air inlet 13 and the air outlet 15 of the heating and drying oven 14. The valve 18 and the second valve 19 form a closed loop of the gas path. After the airflow passes through the air inlet 13, it passes through the heating sheet 12 to bring the hot air upward from the air-permeable partition 8 into the heating chamber, and brings out the water vapor from the upper air outlet 15, and the airflow with water flow enters the dehumidification component 2 to remove the moisture. The dry air flows from the air inlet 13 into the heating and drying box 14.
[0037] The dehumidification component 2 can be equipped with multiple sets of drying balance components in one machine, and can be connected to the drying balance components in working or non-working state through the first valve 18 and the second valve 19 to improve the utilization rate of the dehumidifying component 2.
