Fig. 1 is a device for reducing the thickness of an explosion-proof plate of a high-pressure test chamber according to an embodiment of the present application, and as shown in fig. 1, the device for reducing the thickness of an explosion-proof plate of a high-pressure test chamber according to an embodiment of the present application includes: the device comprises a honeycomb-shaped cylinder 1, a first explosion-proof sheet 2 and a second explosion-proof sheet 3, wherein the cylinder is arranged between a high-pressure experiment bin and an air outlet, the first explosion-proof sheet 2 is arranged between the honeycomb-shaped cylinder 1 and the high-pressure experiment bin, and the second explosion-proof sheet 3 is arranged between the honeycomb-shaped cylinder 1 and the air outlet; the end face of the honeycomb-shaped cylinder 1 is also provided with a vent hole for discharging mineral powder when the explosion-proof sheet is broken, and the pressure P in the high-pressure test chamber can be balanced by injecting high-pressure gas between the first explosion-proof sheet 2 and the second explosion-proof sheet 30Thereby reducing the thickness of the first rupture disk 2.
In the embodiment, the outer sleeves of the first explosion-proof sheet 2 and the second explosion-proof sheet 3 are connected with the high-pressure experiment bin through a split ring.
The honeycomb cylinder in this embodiment is provided with a plurality of circular holes 4 for discharging ore powder when the first explosion-proof sheet is broken. The number of the round holes is calculated by the following formula:
wherein D is the diameter of the cylinder, D is the inner diameter of the high-pressure experiment cabin, and P is the diameter of the cylinder0Is the pressure of the high-pressure experiment chamber, P1Pressure of cylinder, σsIs the strength of the first rupture disk, τsThe shear strength of the first explosion-proof sheet.
Setting the diameter D of the round hole on the honeycomb cylinder to be 6cm, the inner diameter D of the high-pressure experiment chamber to be 20cm, and setting the high-pressure experiment chamber P0150Mpa, low pressure bin P175Mpa, strength of rupture disc, sigmaS350MPa, shear strength τS＝0.6σs210 Mpa.
