Improved hot-reflux extraction and concentration equipment

Abstract

The invention discloses improved hot-reflux extraction and concentration equipment, which at least comprises a concentration tank, an extraction tank, a pump body and circulation pipelines. The concentration tank, the extraction tank and the pump body are connected with one another by the circulation pipelines; the circulation pipelines at least comprise a pipeline I, a pipeline II, a pipeline III and a spray ring, wherein the concentration tank, the extraction tank and the pump body are communicated by the pipeline I, the concentration tank and the extraction tank are communicated with each other by the pipeline II, the pump body is communicated with the pipeline II by the pipeline III, and the pipeline II is communicated with the spray ring to be fixed in the concentration tank; a valve is arranged on the pipeline II and is positioned between the concentration tank and the pipeline III; and the pump body is a screw pump. Compared with the prior art, the improved hot-reflux extraction and concentration equipment disclosed by the invention fully utilizes heat energy of a tank body above a liquid level, effectively enlarges an evaporation surface, and has the advantages of enhancing extraction efficiency, ensuring uniform mass of a concentrated solution, shortening concentration time, reducing concentration energy consumption, strengthening defoaming capacity in a concentration process, thoroughly solving the problem of coking on a tank wall, and the like.

Description

technical field [0001] The invention relates to an improved heat reflux extraction and concentration equipment Background technique [0002] The small heat reflux extraction and concentration equipment is mainly used in medicine, spice extraction and other industries. The concentration method adopts the boiling evaporation method, the evaporation rate is slow, the energy consumption is large, the high temperature boiling time is long, and the active ingredients are easy to change. Coking; many substances tend to generate a lot of foam when boiling. The original equipment installs a mesh method at the vacuum suction port of the concentration tank to intercept and defoam. The effect is poor, and the foam generated during the boiling process in the concentration tank cannot be actively eliminated. The generation affects the evaporation efficiency. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides a novel heat reflu...
