Dissolving pot used in ground turpentine and/or middle-layer turpentine liquid dissolving process and dissolving method thereof

The invention relates to a dissolving pot used in a ground turpentine and/or middle-layer turpentine liquid dissolving process. The dissolving pot comprises a dissolving pot body, an upper discharge tube, a dissolving steam pipe, a pressing steam pipe and a drain pipe; the dissolving steam pipe is communicated with the pressing steam pipe on the upper part; the lower end of the dissolving pot body has an inverted cone structure, and the bottom of the dissolving pot body is provided with a bottom slag discharge tube; impurities with a large specific gravity are easy to precipitate and are discharged through the bottom slag discharge tube based on a gravity force; and the materials are not in contact with the impurities when the turpentine is discharged, therefore the losses of soluble oil and the turpentine are reduced. In the invention, because the dissolving pot with a conical bottom is used, the impurities with the large specific gravity are easy to precipitate and discharge; the materials are not in contac
