Heat insulation supporting device

Disclosed is a heat insulation supporting device. The device includes a supporting structure and a heat insulation structure. The supporting structure includes a mounting flange, an upper annular supporting cylinder, a horizontal annular supporting plate, a lower vertical annular supporting cylinder, a sealing ring, and a volute. The heat insulation structure includes a special-shaped thin-walledoxygen-free copper plate and a heat insulator. The inside of the supporting structure is filled with the heat insulator. The heat insulation supporting device has the following advantages: an embeddedclosed annular fluid passage is formed by the outer surface of the supporting structure and the sealing ring, the structure is simple, and the reliability is strong. the heat is brought into a cooling fluid in the annular fluid passage to form a cold anchor by adding the special-shaped thin-walled oxygen-free copper plate and utilizing the characteristic of device that the heat conductivity increases at low temperature, a
