Description

Technical Field

[0001] The utility model belongs to the technical field, and in particular relates to a water extraction device for continuous production. Background Art

[0002] The continuity, rationality, ease of operation and extraction efficiency of the design of Chinese medicine water extraction equipment are important factors affecting the extraction process of Chinese medicine. The existing extraction equipment still has certain defects in controlling the continuity of production, production capacity, ease of operation and extraction rate. Specifically, it is manifested in: 1. Poor production continuity. The water extraction process needs to go through soaking extraction, concentration and cleaning processes. In order to ensure the continuity of production, it is necessary to design a reasonable pipeline connection structure to ensure the effective and orderly connection between one process and the next process. It is important to ensure the automatic transmission of materials without human intervention. Some existing devices cannot ensure the continuity of production, and human intervention is required in the middle to proceed to the next step; 2. In terms of rationality, Chinese medicine extraction is a continuous production process. There are certain intersections and correlations between each process. It is necessary to ensure the reasonable handover and operation between processes to ensure the continuity and stability of production. However, the rationality of the pipeline connection and valve position design of the current process equipment is poor, and operators need to intervene manually. At the same time, there are also situations where process jams occur during the production process and require manual processing; 3. In terms of production capacity, in existing equipment, when there is a demand for more production capacity, there is a certain gap in production capacity supply; 4. In terms of ease of operation, there are still certain problems in the structural design of large-scale extraction equipment. There are situations where operators are unbalanced in production operation, control is not profitable, and some special situations cannot be handled; 5. In terms of flexibility, when multiple process drugs need to work and produce at the same time, multiple and multiple production process structures need to be set up for extraction; Utility Model Content

[0064] In a specific implementation, if the cost of the Chinese medicine is high, the first extraction device is used for extraction. The present application sets up multiple first extraction devices, which can process multiple Chinese medicines at the same time and extract the effective components of multiple Chinese medicines;

[0065] Put the Chinese medicinal materials to be processed into the first extraction tank 1, open the first valve 6 and the second valve 7, and heat the first extraction tank 1. The water is converted into gas in the heated state. The gas in the first extraction tank 1 is cooled by the first condensation tank 3 and the second condensation tank 8.

The present application can process different traditional Chinese medicines at the same time and extract the traditional Chinese medicines. The first extraction device needs to extract repeatedly through "extraction + concentration" to finally extract the ointment. During the extraction process, the hot solvent is continuously added to the medicine surface, and passes through the medicinal material layer at high speed from top to bottom to dissolve the solute in the medicinal material. The solute content in the medicinal material and the solute content in the solvent maintain a high gradient. The solute in the medicinal material is dissolved at a high speed until it is completely dissolved, and the extraction rate of the effective ingredient is high, so the ointment collection rate is high and the content of effective ingredients in the ointment is high. The ointment yield of the second extraction device is 10-15% lower than that of the first extraction device, which reduces the loss of medicinal materials.

[0073] The first extraction device is suitable for the extraction of some high-cost Chinese medicines, and the second extraction device is suitable for the extraction of some low-cost Chinese medicine residual liquids, and can be used for the extraction of Chinese medicine ointments from different Chinese medicine residual liquids. The second extraction device has the advantages of low energy consumption and high degree of automation, which can accelerate the dissolution of solutes, small equipment footprint, and save industrial steam, and has the characteristics of energy saving and consumption reduction.

[0074] The production continuity of this application is improved. Through reasonable pipeline connection design, device design and overall layout design, the continuity of the production process is guaranteed, and people are not or rarely involved in the production from soaking to extraction to cleaning. In terms of rationality, the connection structure is optimized to ensure the reasonable handover and operation between processes, without conflict between processes, and the production process requires little or no human intervention. In terms of production capacity and flexibility, two single-effect systems and a heat reflux system are set in the equipment, which can improve production capacity and flexibly realize the extraction of traditional Chinese medicine for various processes. In terms of production flexibility, two sets of extraction and concentration tanks and a heat reflux unit are configured to ensure the simultaneous production of various production process products, and at the same time, flexible and adaptable selection of processes can be made through "extraction + concentration" and "heat reflux".
