[0033] When in use, each high-pressure warehouse, high-pressure barrel and high-pressure pipeline is first inspected through the external mixing system to ensure that each high-pressure warehouse, high-pressure barrel and high-pressure pipeline is in an idle state. The recipe data of each corresponding high-pressure warehouse and high-pressure barrel is read through the external display and controller. First, the pneumatic ball valve A51, the pneumatic ball valve B52 or the pneumatic ball valve C53 is opened. According to the user's setting on the control screen, the corresponding pneumatic ball valve B52 or pneumatic ball valve C53 is opened. When the pneumatic ball valve B52 is opened, cold water can be delivered from the cold water pipeline 902. When the pneumatic ball valve C53 is opened, hot water can be delivered from the hot water pipeline 903. At the same time, the flow meter 56 measures the water injection volume and the accumulated flow, and displays them on the screen in real time. When the flow reaches the recipe setting value, the pneumatic ball valve B is closed. 52 or pneumatic ball valve C53. Similarly, according to the recipe settings, open the switches of the corresponding solid warehouse 2, liquid warehouse body No. 1 401 and liquid warehouse body No. 2 402, open the pneumatic butterfly valve 801 on the tube feeder 8, start adding materials, and at the same time, the pneumatic vibrator 201 vibrates according to the set frequency.

The liquid pipeline 404 transports the liquid to the premixing barrel 1, and the liquid is measured by the metering pumps arranged on the No. 1 liquid pipeline 403 and the No. 2 liquid pipeline 404. After reaching the formula set value, it is closed and the material and liquid are stopped from being transported to the inside of the premixing barrel 1. At the same time, after the tubular feeder 8 has completed the feeding of all the materials in the corresponding solid bin 2, it is delayed for a certain time and the tubular feeder 8 stops to ensure that the material remaining in the tubular feeder 8 is also transported to the premixing barrel 1. Then the stirring motor 101 is started and stopped after the system set time is reached. The operating time can be determined according to the amount of water and material in the formula, or determined according to the delay of the last material. After the stirring motor 101 stops rotating, the pneumatic ball valve D54 and the slurry delivery valve on the raw slurry pipeline 901 are opened. Pump 59, the slurry delivery pump 59 starts to run and starts to deliver slurry to the interior of the premixing barrel 1.

Then the pneumatic ball valve B52 on the cold water pipeline 902 or the pneumatic ball valve C53 on the hot water pipeline 903 is opened, and the pneumatic ball valve A51 on the water inlet pipeline 904 is opened at the same time. This process only delivers water to the interior of the premixing barrel 1, and then the stirring motor 101 is started to stir the added water and materials evenly and mix them. When the water injection is completed, the stirring motor 101 is stopped again. After the stirring motor 101 stops, the pneumatic ball valve B52 on the cold water pipeline 902 or the pneumatic ball valve C53 on the hot water pipeline 903 is opened.The clean water is allowed to enter the interior of the premixing barrel 1, and the clean water is initially delivered to the premixing barrel 1. Similarly, the stirring motor 101 is then started to stir the added water and the material evenly. When the water injection is completed, the stirring motor 101 is stopped again. This cycle is repeated, and clean water can be delivered to the interior of the premixing barrel 1 for the second time and mixed with the material evenly, thereby completing the slurry mixing. In addition, when the material stored in the solid warehouse 2 reaches the set value, an alarm is triggered to remind you to add material. Similarly, when the solution in the No. 1 liquid warehouse 401 and the No. 2 liquid warehouse 402 reaches the set minimum value, an alarm is triggered, and the No. 2 infusion pump 510 and the No. 1 infusion pump 511 are started at the same time, and the No. 1 infusion pipe 601 and the No. 2 infusion pipe 701 are respectively fed to the No. 1 and No. 2 liquid warehouses. The solution is transported into the No. 1 liquid tank 401 and the No. 2 liquid tank 402. When the maximum value is reached, the transport is stopped. After the sizing is completed and the machine is shut down, the pneumatic ball valve B52 or the pneumatic ball valve C53 is opened, the pneumatic ball valve A51 is closed, and clean water enters the cleaning ring pipe 102 through the water inlet pipe 904 and the cleaning pipe 905. The inner wall of the premixing tank 1 can be rinsed through the cleaning ring pipe 102. At the same time, the stirring motor 101 is running. After the premixing tank 1 is fully rinsed, the pneumatic ball valve B52 or the pneumatic ball valve C53 is closed, the stirring motor 101 is stopped, and the pneumatic ball valve E55 is opened to discharge the cleaning waste liquid in the premixing tank 1 through the waste liquid pipe 104. After completion, the pneumatic ball valve E55 is closed and the machine is shut down.
