The present invention proposes a non-contact high-temperature mechanical sealing device, including a shaft sleeve, a dynamic ring, a static ring, a pumping ring, a pumping blade I, a pumping blade II and a secondary gland. The shaft sleeve is provided with a pumping hole I and a pumping hole II. By utilizing the rotation of the shaft, a structure of four pumps in series, such as the pumping hole I, the pumping hole II, the pumping blade I and the pumping blade II, is adopted, so that the coolant flows sequentially around the inner cavity of the dynamic and static rings, taking away the heat applied to the sealing ring and the lubricating film by the high-temperature medium and the friction of the sealing surface, reducing the temperature of the sealing ring and the lubricating film, inhibiting the evaporation of the lubricating film, and improving the effect of the mechanical seal. The pumps are connected in series to form a strong coolant delivery driving force, which can realize the self-circulating flow cooling of the coolant. At the same time, the pumping capacity of the pumping holes I, II and the pumping blades I, II is positively correlated with the sealing speed. When the speed increases and the friction temperature rise of the sealing end face increases, the pumping capacity can be automatically increased, the cooling strength can be increased, and the effect of automatically adjusting the cooling intensity can be achieved.
