Liquid extraction system and extraction method

Abstract

The invention discloses a liquid extraction system, which includes a precipitation tank equipped with a lifting liquid outlet pipe. The liquid extraction system further comprises a light-transmittingpipeline sight glass, an image acquisition and recognition device, an electrical control device used for receiving an image recognition signal and a control valve used for receiving a valve shutoff signal. One end of the lifting liquid outlet pipe extends into the precipitation tank, and the other end of the lifting liquid outlet pipe is connected with an external device for collecting a liquid through the light-transmitting pipeline sight glass and the control valve. The invention further discloses a liquid extraction method. The method comprises the following steps: a liquid outlet pump is arranged on an external pipe of the lifting liquid outlet pipe; the liquid outlet pump is started; the image acquisition and recognition device is used for photographing and recognizing a supernatant flowing through the light-transmitting pipeline sight glass; and when it is recognized that settled medicine residues appear in the picture, the control valve executes valve shutoff operation. The liquid extraction system and the extraction method have the advantages that the operation is simple, whether the extraction of the supernatant is completed or not can be timely and accurately judged, andthe influence on the supernatant due to the entrance of settled medicine residues into the extracted supernatant can be avoided.

Description

technical field [0001] The invention relates to the technical field of food and medicine packaging machinery and equipment, in particular to a liquid extraction system and extraction method. Background technique [0002] The supernatant obtained by alcohol precipitation of traditional Chinese medicine in the traditional alcohol precipitation tank is judged by manual observation. Manually operate the liquid extractor and observe through the observation hole of the equipment to see whether there is sediment in the liquid taken. In this way, the liquid extraction operation is difficult, and it is difficult to accurately determine the Whether the clear liquid is taken out is completed, it is easy to bring into the sedimented medicine residue, resulting in impure liquid. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, to provide a method that is simple to operate, can accurately det...
