Embodiment 1

[0026] like figure 1 , 2 shown. Query the characteristics of reagents and preparation precautions through PLC10, and perform calculations and settings. Several solid raw materials can be added at the same time through the switching of the material selection device 2, and can be added accurately through the large amount of feeding rotary wheel and the micro-feeding rotary wheel of the solid feeding device 3. Under the action of the stirring device 8, it is fully stirred. If it is necessary to heat up, you can also Heating is performed under the action of the heating device 7, and when the temperature needs to be measured, the temperature sensor 6 and the programming controller PLC10 can be used for measurement, control and output, including display, and then the printer 12 prints out the result. Solid-solid preparation can be realized accurately and conveniently.

Embodiment 2

[0028] like figure 1 , 2 Shown: through the programming controller PLC10 query reagent characteristics, and preparation precautions, calculation and setting. PLC10 controls several kinds of solid raw materials can be added at the same time by switching the material selection device 2, and controls the solid feeding device 3 to add accurately, and accurately weighs the quality of the solid materials through the precision balance 9, and the data information is automatically imported into the programming controller PLC10. Set the target concentration, accurately calculate the required solvent quality through the programming controller PLC10, add liquid through the liquid feeder 4, the large flow port of the fast flow solenoid valve, and automatically switch to the small flow port to achieve accurate addition when the liquid is close to the target amount. Under the action of the stirring device 8, fully stir, if the temperature needs to be raised, it can also be heated under the ...

Embodiment 3

[0030] like figure 1 , 2 Shown: Query the characteristics of the reagents and preparation precautions through the programming controller PLC10. Through the switching of the liquid material selection device, more than two kinds of liquids can be added simultaneously or successively. The liquid feeder 4 can accurately add the liquid material, and the precision balance 9 can accurately weigh the quality of the liquid material, and the data information is automatically imported into the program controller of the program control device. PLC10, according to the set target concentration, accurately calculate the required solvent quality through the programming controller PLC10, add liquid solvent through the liquid feeder 4 and the fast flow solenoid valve 13, and automatically switch to the precision flow solenoid when the liquid is close to the target amount The valve 14 is added slowly, under the action of the stirring device 8, fully stirred, if the temperature needs to be raise...
