For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] Embodiment 1, combination Figure 1-Figure 5 To illustrate this embodiment, a metallurgical pressure storage tank of this embodiment includes a main device 1, an outer shell device 2 and a lifting device 3. The main device 1 is arranged in the outer shell device 2. The outer shell device 2 includes an outer shell 201, support legs 202 and a protective filler 203. The main tank body 101 of the main device 1 is installed in the outer shell 201. The protective filler 203 is filled between the main tank body 101 and the outer shell 201. A plurality of support legs 202 are installed at the bottom of the outer shell 201. The lifting device 3 is installed on the outer shell 201. The lifting device 3 is used to assist in lifting the outer shell device 2.

[0024] The main tank body 101 of the main device 1 is used to contain and store metallurgical pressure gas. An inlet and outlet pipe 102 is arranged on the top of the main tank body 101, and an electric control valve 103 is installed on the inlet and outlet pipe 102. A pressure gauge 104 is arranged on one side of the inlet and outlet pipe 102, and a safety valve 105 is arranged on one side of the pressure gauge 104. A slag discharge pipe 106 is arranged at the bottom of the main tank body 101, and a slag discharge valve 107 is installed on the slag discharge pipe 106. The inlet and outlet pipe 102 and the slag discharge pipe 106 are welded to the main tank body. On the main tank 101, the pressure gauge 104 and the safety valve 105 are respectively connected with the main tank body 101 with sealing threads, and the inlet and outlet pipes 102 are controlled by the electric control valve 103 to transport or discharge gas into the main tank body 101. The pressure gauge 104 is used to display the pressure in the main tank body 101, and the safety valve 105 ensures that the pressure in the main tank body 101 is automatically released when the pressure is too high. When the main tank body 101 is maintained, the slag discharge valve 107 is opened to discharge the waste slag in the main tank body 101 from the slag discharge pipe 106;

[0025] The outer shell 201 of the outer shell device 2 is cylindrical and made of Q235 steel. A plurality of supporting legs 202 are evenly distributed at the bottom of the outer shell 201.

The outer wall of the protective filler 203 is pasted on the inner wall of the outer shell 201. A avoidance hole 204 is processed at the bottom of the protective filler 203. The supporting legs 202 pass through the outer shell 201 to form a main tank body 101 wrapped by the protective filler 203 to prevent collision and damage to the main tank body 101. When the main tank body 101 explodes, the protective filler 203 absorbs part of the explosion kinetic energy, while the outer shell 201 directs the explosion kinetic energy upward to reduce damage.

[0026] The lifting device 3 includes a connecting seat 301, which is in a circular shape and is bolted to the outer shell 201. Two lifting rings 302 are symmetrically arranged on the connecting seat 301. The lifting rings 302 and the connecting seat 301 are welded together.
