When the device is actually operated, the device is connected with a pressurized material system in a production laboratory and a laboratory, and when the pressurized material system in the production laboratory and the laboratory transfers pressurized fluid materials to be unloaded to the device through a pipeline, the specific working process is as follows:
1. the PLC1 control module closes the electric valve 12 of the pressurized storage tank and the first electric balance valve 21; opening an inlet 18 of the pressurized storage tank, and allowing a pressurized fluid type material (which consists of pressurized fluid and a small amount of solid coarse particles, wherein the specific gravity of the solid coarse particles is greater than that of the pressurized fluid, and the fluid is water for example) to enter the pressurized storage tank 1 from an external pressurized system through an external connecting pipe 6 and the inlet 18 of the pressurized storage tank; the pressurized fluid in the pressurized storage tank 1 is returned to the external pressurized material system through the fluid outlet 13.
The material (solid coarse particles) is accumulated in the pressurized storage tank 1.
2. When the material (solid coarse particles) is accumulated to reach the detection height of the high level gauge 16 of the pressurized storage tank, the PLC1 control module slowly opens the electric valve 12 and the electric balance valve I21 of the pressurized storage tank;
the materials enter the pressure-changing storage tank 2 through a pipeline provided with the electric valve 12 of the pressure-changing storage tank due to the self-weight effect, and the pressure in the pressure-changing storage tank 1 and the pressure-changing storage tank 2 is kept consistent through a first balance bypass 22 in the process; when the material descends to the detection height of the low level indicator 17 of the pressurized storage tank, the PLC1 control module closes the electric valve 12 of the pressurized storage tank and the first electric balance valve 21, and ensures that the electric valve 23 of the variable pressure storage tank and the second electric balance valve 32 are in a closed state in the whole discharging process of the material discharged from the pressurized storage tank 1; namely, when the electric valve 12 of the pressurized storage tank is opened, the electric valve 23 of the variable pressure storage tank and the second electric balance valve 32 are closed.
3. When the material accumulation in the variable-pressure storage tank 2 reaches the detection height of the variable-pressure storage tank high level indicator 26, the PLC2 control module slowly opens the variable-pressure storage tank electric valve 23 to enable the material in the variable-pressure storage tank 2 to gradually fall into the normal-pressure storage tank 3 through a pipeline provided with the variable-pressure storage tank electric valve 23, and meanwhile, the PLC2 module controls the second electric balance valve 32 to be opened to enable the pressure of the variable-pressure storage tank 2 and the normal-pressure storage tank 3 to be balanced; when the materials in the variable pressure storage tank 2 drop to the detection height of the variable pressure storage tank low level indicator 27, the PLC2 control module closes the variable pressure storage tank electric valve 23 and the electric balance valve II 32, and the normal pressure storage tank electric valve 34 is ensured to be in a closed state in the whole discharging process of the materials from the variable pressure storage tank 2.
4. When the material accumulation in the normal pressure storage tank 3 reaches the detection height of the normal pressure storage tank high level indicator 36, the PLC3 control module opens the normal pressure storage tank electric valve 34 and starts the unloader 4, the material in the normal pressure storage tank 3 falls into the unloader 4 through the pipeline provided with the normal pressure storage tank electric valve 34 and enters the stock bin 5 through the unloader 4, thereby realizing the automatic unloading operation; when the material in the normal pressure storage tank 3 is lowered to the detection height of the normal pressure storage tank low level gauge 37, the PLC3 control module closes the normal pressure storage tank electric valve 34 to complete the whole process of discharging under pressure.
