The invention discloses a device and a method for high-temperature continuous acidification precipitation separation of a traditional Chinese medicine extracting solution. The device comprises a high-temperature acidification reaction kettle, an acidification suspension liquid separation column, an acidification precipitate collecting and cleaning kettle, a clear liquid collecting kettle, a vacuumsystem, a material switch valve, a connecting pipeline and the like, wherein the upper end of the high-temperature acidification reaction kettle is connected with a raw material reaction liquid pipeline, the high-temperature acidification reaction kettle is connected with the lower inlet end of the acidification suspension liquid separation column, the upper outlet end of the acidification suspension liquid separation column is communicated with the clear liquid collecting kettle, a tetrafluoro filtering plate is arranged at the outlet of the acidification suspension liquid separation column,the lower end of the acidification suspension liquid separation column is communicated with the acidification precipitate collecting and cleaning kettle through a material switch valve; the lower endof the acidification precipitate collecting and cleaning kettle is communicated with the acidification precipitate collecting and cleaning kettle through the material switch valve, the lower end of the acidification precipitate collecting and cleaning kettle is communicated with the clear liquid collecting kettle, and the tetrafluoro filtering plate is arranged between the acidification precipitate collecting and cleaning kettle and the clear liquid collecting kettle. According to the invention, with the device and the method, the problems that the traditional Chinese medicine acidification substances cannot be rapidly and continuously separated and acidified at a high temperature, high corrosion is generated and the like are solved, the production is easy, the continuous degree is high,and the purity of the traditional Chinese medicine acidification products is high.
