Technical Field

[0001] This invention relates to the field of Astragalus membranaceus pulp processing technology, specifically to a device for removing impurities from Astragalus membranaceus pulp by allowing it to stand. Background Technology

[0002] Currently, the industry typically uses natural settling to remove impurities from Astragalus membranaceus pulp. This involves injecting the pulp into a storage tank and letting it stand for 12 to 24 hours, allowing insoluble impurities to settle naturally to the bottom of the tank under gravity, and then extracting the clear liquid from the top.

[0003] However, in practice, the thickness of the sediment layer produced by each settling operation is difficult to keep consistent. Operators can only rely on experience to estimate the amount of clear liquid extracted from the upper layer. Therefore, a settling and impurity removal device for Astragalus membranaceus pulp is needed to solve the above problems. Summary of the Invention

[0030] The technical solutions of the present invention will now be clearly and completely described with reference to the accompanying drawings. Example

[0031] Referring to the accompanying drawings, this invention provides a device for the static sedimentation and impurity removal of Astragalus membranaceus extract. Through the combination of precise layered liquid extraction and intelligent sedimentation identification, it achieves efficient static sedimentation and precise extraction of the clarified liquid from Astragalus membranaceus extract. Its specific structure is as follows: The storage mechanism 100 is the core container for pulp sedimentation, including storage tank 111, raw liquid pipe 112, drain pipe 113 and cleaning pipe 114. Storage tank 111 is made of food-grade 304 stainless steel and is divided into two parts: tank body 1011 and tank cover 1012. It is sealed and fixed by flange for easy internal inspection and maintenance. Tank body 1011 has a cylindrical structure to meet the needs of batch pulp sedimentation. The bottom of storage tank 111 is funnel-shaped to facilitate the concentrated sedimentation into the opening of drain pipe 113, reducing sediment residue. In addition, the raw liquid pipe 112 is connected to the upper end of the tank 1011 and is equipped with a pneumatic valve body for inputting the Astragalus raw liquid; the drain pipe 113 is connected to the bottom center of the tank cover 1012 and is equipped with a pneumatic valve body for discharging sediment impurities; the cleaning pipe 114 is embedded in the upper part of the storage tank 111 and is equipped with an external water supply pump body for supplying clean water. The nozzle section of the cleaning pipe 114 is a ring-shaped or bifurcated diversion area 1041, which can realize multi-angle water spraying, improve the cleaning uniformity of the inner wall of the storage tank 111, and reduce raw liquid residue.

[0032] The liquid extraction mechanism 200 includes a clear liquid pipe 211, a collection pipe 212, an observation window 213, an electric control valve 2011, and an identification camera 2031, which realizes the precise extraction of clear liquid and intelligent identification of sedimentation height. Several clear liquid pipes 211 are embedded in the side wall of the storage tank 111 in a straight line, with a quantity of 2 to 5 pipes, for extracting clear liquid at different heights. Each clear liquid pipe 211 is equipped with an electric control valve 2011, which is an electric ball valve that can precisely control the opening and closing of the clear liquid pipe 211. At the same time, the collection pipe 212 is connected to the drain outlet of several clear liquid pipes 211, which facilitates the collection of clear liquid at different heights and its transportation to the next process. In addition, the observation window 213 is made of high borosilicate glass and is embedded in the side wall of the storage tank 111. Its height is half the height of the tank body 1011, which makes it easy to observe the sedimentation height inside the storage tank 111. The surface of the observation window 213 is coated with scale lines, which can intuitively determine the specific sedimentation height. It is equipped with an industrial high-definition camera 2031, which is installed in front of the observation window 213. It can capture the sedimentation height at the observation window 213 in real time. The recognition camera 2031 is electrically connected to the main control unit and automatically identifies the sedimentation height through image recognition algorithm.

[0033] The main control unit of this device adopts a PLC programmable logic controller and integrates a touch screen operation interface, which can realize the following functions: The automated control specifically includes the automatic opening and closing of the raw liquid pipe 112, the sewage pipe 113, and the electric control valve 2011. Sediment height recognition specifically involves receiving image data from the recognition camera 2031, automatically recognizing the sediment height, and opening the corresponding electrically controlled valve 2011 according to preset logic. The process parameters can be set, specifically including sedimentation time, washing time, liquid flow rate, and other process parameters. Data recording and querying specifically involves recording data such as the time and flow rate of each sedimentation, liquid extraction, and cleaning process, facilitating production traceability.

[0034] The specific principle is as follows: Original pulp sedimentation stage Open the pneumatic valve of the raw liquid pipe 112 and add the Astragalus raw liquid into the storage tank 111 through the raw liquid pipe 112. After the set liquid level is reached, close the valve of the raw liquid pipe 112 and start the sedimentation timer. Let it stand and settle for 12-24 hours according to the process requirements, so that the impurities in the raw liquid can naturally settle to the bottom of the storage tank 111.

[0035] Intelligent liquid extraction stage After sedimentation is complete, the recognition camera 2031 automatically captures an image at the observation window 213 and transmits it to the main control unit. At this time, the main control unit determines the sedimentation height through the image recognition algorithm and automatically opens the corresponding electric control valve 2011 above the height. The clear liquid flows into the manifold 212 through the clear liquid pipe 211 and is centrally transported to the next process. When the liquid level drops to the sedimentation height, the main control unit automatically closes the electric control valve 2011 to stop liquid extraction.

[0036] Sewage discharge and cleaning stage Open the pneumatic valve of the drain pipe 113, and the sediment at the bottom of the storage tank 111 will be collected and enter the drain pipe 113 through the funnel-shaped structure and discharged into the collection container. In addition, the pneumatic valve of the cleaning pipe 114 is opened periodically, and clean water is evenly sprayed onto the inner wall of the storage tank 111 through the diversion area 1041 to rinse away the residual slurry and impurities. The wastewater after rinsing is discharged through the drain pipe 113. If a thorough cleaning of the interior of storage tank 111 is required, the flange can be removed, the tank cover 1012 can be opened, and manual cleaning and maintenance can be performed.
