[0020] In this embodiment, a discharge port is provided at the bottom of the hopper 1 and is connected to the feed port at the lower end of the automatic loader, so as to realize automatic interlocking control of feeding; the discharge port at the upper end of the loader 2 is connected to the feed port of the grinding feeding device 3, so as to realize operation interlocking regulation of feeding and material quantity; the grinding unit at the upper end of the grinding spiral feeding device 3 receives the flake caustic soda from the loader and grinds it, and after grinding, the particles are discharged to the frequency-modulated spiral feeding unit at the lower end, and the spiral feeding unit controls the feeding amount by frequency modulation, so as to realize operation interlocking regulation of feeding and material quantity.

[0021] In this embodiment, the solid dissolution tank 4 and the finished liquid caustic soda tank 7 are equipped with a frequency modulation mixer. The frequency modulation mixer has a single-layer blade or a double-layer blade. The speed of the frequency modulation mixer is set according to the solubility, viscosity, dissolution time and stirring intensity of the flake caustic soda.

[0022] In this embodiment, a water supply port 5 is provided at the upper end of one side of the solid dissolution tank 4, and a liquid alkali outlet 6 is provided at the lower end of the other side.
