Vacuumizing device for low-temperature heat insulation liquid storage tank

The invention provides a vacuumizing device for a low-temperature heat insulation liquid storage tank. Comprising a base, a walking supporting module, an L-shaped mounting frame, a linear sliding table, a first telescopic push rod, a mounting frame, a transverse air exhaust module transversely arranged at the left side end of the mounting frame, a vertical air exhaust module vertically arranged at the bottom of the mounting frame, a vacuumizer arranged at the top of the base and a tee joint arranged at the air inlet end of the vacuumizer. The first air guide module is arranged between the tee joint and the transverse air exhaust module; and the second air guide module is arranged between the tee joint and the vertical air exhaust module. And a reinforcing rod is arranged between the horizontal part and the vertical part of the mounting frame. By means of the vacuumizing device for the low-temperature heat insulation liquid storage tank, vacuumizing treatment on the storage tank can be independently completed,
