Description

Efficient filtering device for extracting and processing traditional Chinese medicinal materials and filtering method thereof Technical Field The invention belongs to the field of filtration, and particularly relates to a high-efficiency filtration device for extracting and processing traditional Chinese medicinal materials and a filtration method thereof. Background In the current mainstream traditional Chinese medicine property component extraction device, a water extraction process is generally adopted, the traditional Chinese medicine is soaked in water in an extraction tank, then the effective components are dissolved out by heating, after the core solid-liquid separation operation is completed, the medicine liquid is uniformly mixed by a stirring mechanism arranged in the extraction tank, the concentration of the liquid medicine is ensured to be uniform and consistent, the primarily clarified liquid medicine liquid is returned to the liquid storage tank, and a filtering device is generally additionally arranged in a liquid return pipeline to form the final protective barrier of the liquid medicine cleanliness aiming at fine particles possibly remained in the liquid medicine so as to ensure the stable operation of subsequent procedures. One patent application with publication number of CN118576987A discloses a medicine property component extraction device based on traditional Chinese medicine processing, which comprises an evaporation tank and a liquid storage tank, wherein the bottom of the evaporation tank is connected with an extraction pipe, the side part of the liquid storage tank is connected with a liquid return pipe, a filter residue screen plate is installed in the extraction pipe, the top of the filter residue screen plate is connected with a screen plate control cylinder, a traveling seat is connected above the screen plate control cylinder, the traveling seat is movably connected with a steering gear plate, a fixed wall is installed at the inner side of a pipe hollow chamber, a return tension spring for resetting is installed between a translation block and the fixed wall, the screen plate can be driven to realize one-time overturning by rotating the screen plate control cylinder by 180 degrees, so that the originally blocked surface of the filter residue screen plate is converted to the rear, solid impurities on the filter residue screen plate are backflushed by medicine liquid, and the blockage is relieved. One patent application with publication number of CN202061552U discloses an ultrafiltration component system device for yellow wine filtration, which comprises two ultrafiltration components, wherein one end of each ultrafiltration component is provided with an inlet pipe and a cleaning fluid discharge pipe respectively, the other end of each ultrafiltration component is provided with an outlet pipe, the side ends of each ultrafiltration component are provided with a concentrated solution discharge valve respectively, and the inlet pipes of the two ultrafiltration components are led out from a stock solution total inlet pipe. The main precondition of the scheme one is to close the liquid returning pipe and open the waste liquid pipe, the liquid medicine mixed with solid impurities in the backflushing process can be directly discharged from the waste liquid pipe, the backflushing medium is essentially the liquid medicine to be collected, the backflushing and the waste discharge are synchronously carried out, the liquid medicine is equivalent to the liquid medicine to be directly discarded after the solid impurities are washed, the liquid medicine loss rate can be accumulated along with the increase of the backflushing times, and the production cost is obviously improved. When the scheme II is operated, the ultrafiltration component can be in a standby state, filtered yellow wine can be used as backflushing liquid, the stock solution, namely the yellow wine to be filtered, cannot be diluted, and cannot cause pollution, but the backflushing liquid is equivalent to large circulation in the system, so that energy consumption and equipment burden of links such as pumping, pipeline conveying and the like are increased, after backflushing is finished, the backflushing liquid is conveyed back to the stock solution main inlet pipe through the cleaning liquid discharge pipe and enters the system again for filtering after being mixed with fresh stock solution, the backflushing liquid returns to the stock solution inlet, which means that the liquid needs to undergo a complete filtering process again, and the stock solution main inlet pipe, through the ultrafiltration component, is then transmitted to the permeate liquid collecting pipe, which means that the ultrafiltration component in a working state is used for processing fresh stock solution, and additionally bears the backflushing liquid re-filtering task, the actual processing amount is increased, and the fouling and blocking process of the ba
