Separation and purification device with multi-stage filtering function and for plant extract

Abstract

The invention discloses a separation and purification device with a multi-stage filtering function and for plant extract, belonging to the technical field of separation and purification devices. The separation and purification device comprises a separation tank, wherein a first vortex mechanism is arranged on the inner wall of the lower side of the separation tank; a first liquid inlet mechanism is fixedly mounted on the left side face, corresponding to the first vortex mechanism, of the separation tank; a filter plate is fixedly mounted between the inner walls of the separation tank; and a scraping plate is fixedly mounted on the first vortex mechanism corresponding to the filter plate. According to the invention, multi-stage filtration is adopted, the extract is separated and purified tothe greatest extent, and better quality is realized; the fed extract forms vortex rotation, so scouring to a first filtering mechanism and a second filtering mechanism is reduced, and impurity adhesion is reduced; and the buffering functions of the first filtering mechanism and the second filtering mechanism are added, so damage is not likely to happen, service life is long, workers can be reminded, replacement or cleaning is convenient, and working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of separation and purification devices, in particular to a separation and purification device for plant extracts with multi-stage filtration functions. Background technique [0002] Plants are rich in many raw materials, and are natural and pollution-free. Plant extracts use plants as raw materials. According to the needs of the final product of extraction, through the process of physical and chemical extraction and separation, one or more of the plants is indirectly obtained and concentrated. A variety of active ingredients without changing the structure of the active ingredients. According to the different ingredients of the extracted plants, it forms acids, polyphenols, flavonoids, alkaloids, etc.; according to different properties, it can be divided into vegetable oils, extracts, and powders. , lens, etc., but the existing separation and purification device for plant extract also has the following proble...

AI Technical Summary

Problems solved by technology

[0003] 1. In the prior art, a large number of filter screens or filter membranes are used in the separation and purification device. These filter screens or filter membranes are easily damaged during the long-term washing process, have a low service life, and are easily contaminated with impurities, resulting in poor filtering effect. Good, unusable problem;

[0004] 2. In the prior art, the separation and purification device makes the filtration effect poor, resulting in poor product quality. At the same time, the filter screen or filter membrane is replaced or cleaned regularly by workers based on experience, resulting in poor cleaning of the filter screen or filter membrane. Timely or transitional cleaning issues that reduce production efficiency
