Medicine extracting tank

Abstract

The invention discloses a medicine extracting tank, comprising a tank body, a charging port, an exhaust pipe, a slag outlet, an air inlet and a liquid outlet. A heating interlayer is arranged at the outer wall of the tank body; the medicine extracting tank is also provided with a forcible reflux device, comprising a circulation pump, a pipeline and a liquid distribution disc arranged at the bottom of the tank body, the liquid distribution disc is provided with a plurality of upward liquid spraying pipes and is connected with a pump outlet of the circulation pump by a pipeline, a baffle is arranged at the middle of the tank body, an extraction port is formed above the baffle, a pump inlet of the circulation pump is communicated with the extraction port through a pipeline, and a filter screen is arranged above the liquid spraying pipes. Medicine liquid and medicine materials in the medicine extracting tank are uniformly mixed, effective active components of the medicine materials are fast fully extracted.

Description

technical field [0001] The invention relates to a plant extraction device, in particular to a medicine extraction tank. Background technique [0002] Extraction tanks are mainly used for decoction, percolation and warm soaking of Chinese medicinal materials or plants under normal pressure, and are widely used in pharmaceutical, food, chemical and other industries. [0003] The structure of the existing extraction tank generally includes a tank body, the outer wall of the tank is provided with a heating interlayer, the upper part of the tank body is provided with a feed port, and the lower part is provided with a liquid outlet and a slag discharge port. (Usually water or ethanol) is put into the extraction tank through the feed port and mixed, and steam is passed into the heating interlayer or directly into the tank to heat the mixture. During the heating process, the active ingredients are gradually separated from the medicinal materials and dissolved. Enter the solvent to ...

AI Technical Summary

Problems solved by technology

However, the pump is generally used to extract the liquid medicine from the bottom of the tank, and then send it in from the top of the tank, but this will make the material at the bottom of the tank denser and denser, and the backflow of the liquid medicine is only carried out on one side of the tank body, and the rest of the position The mixing effect of the materials is poor, and the reflux mixing effect is not good, so it is easy to cause the problem of uneven mixing of the materials in the tank, so that the active ingredients in some medicinal materials in the tank cannot be extracted in time
