[0041] See also Figure 1 The discharge assembly 15 includes a sealing bottom plate 16 and an electric push rod 17 that drives the sealing bottom plate 16 to move up and down. A push rod support plate 18 is provided at the lower end of the electric push rod 17. The electric push rod 17 is used to drive the sealing bottom plate 16 to move downward. After the mixed thermite flux loses its support, it naturally falls down to achieve discharge.

[0042] See also Figure 5 Lifting handles 12 are provided on both sides of the outer walls at the top of the mixing tank 1, and the lifting handles 12 are welded and fixed to the mixing tank 1.

[0044] Working principle: When in use, the aluminum powder and refractory metal oxide used for the preparation of thermite flux are poured into the first mixing chamber 2, the second mixing chamber 3 and the third mixing chamber 4 in a ratio of 4:6, respectively, to achieve modular mixing, start the AC motor 6, and use the output end to drive the rotating shaft 7 to rotate, so as to realize the rotation of the mixing blades 8 and the connecting frame 9.

The mixing blades 8 rotate inside the first mixing chamber 2, and multiple mixing frames 10, two in a group, rotate inside the second mixing chamber 3 and the third mixing chamber 4 respectively, to mix the first mixing chamber 2. The materials in the second mixing chamber 3 and the third mixing chamber 4 are mixed at the same time, and the triangular seat 11 is used to facilitate the movement of the mixing frame 10 in the materials, thereby reducing resistance and thus reducing energy loss. The existing overall mixing is divided into three module mixing, so that the amount of mixing in each module is less than that of the overall mixing, thereby reducing energy loss and mixing evenly, thereby improving mixing efficiency. After the mixing is completed, the electric push rod 17 is used to drive the sealing bottom plate 16 to move downward. After the mixed aluminum thermite flux loses support, it naturally falls down and falls to the inside of the charging box 14 along the sealing bottom plate 16 to the surrounding areas;
