Description

Technical Field

[0001] This utility model belongs to the field of filtration technology, specifically relating to a traditional Chinese medicine filtration and extraction tank. Background Technology

[0002] In the field of traditional Chinese medicine (TCM) pharmaceutical manufacturing, liquid-solid separation is a crucial step in the extraction process, and traditional TCM extraction and filtration equipment generally suffers from numerous shortcomings. Firstly, most equipment has a single function; filtration and extraction, and residue discharge are usually two separate steps, requiring interruptions to the production process and frequent start-ups and shutdowns. Sometimes, manual cleaning is even necessary, significantly reducing production efficiency, increasing the workload of operators, and posing a high risk of secondary contamination due to human contact. Secondly, after centrifugal filtration, viscous solid residue easily adheres to and remains on the inner wall and bottom of the filter cylinder. Traditional methods struggle to thoroughly and automatically remove these residues, leading to waste of medicinal materials and potential cross-contamination between different batches of medicine due to incomplete cleaning, severely impacting product quality uniformity and safety. Thirdly, existing equipment has a low level of automation and integration; the entire extraction, filtration, and residue discharge process lacks continuity, failing to form a closed, continuous, automated production system, and thus failing to meet the stringent requirements of modern Good Manufacturing Practices (GMP) for efficient and clean production. Therefore, the industry urgently needs a traditional Chinese medicine filtration and extraction device that can integrate efficient extraction, centrifugal filtration and automatic and thorough slag discharge, and operate in a fully closed and automated manner.

At this time, the centrifugal motor 9 is activated again, which makes the extraction screen cylinder 3 rotate, so that the solid waste drug quickly falls through the discharge port 301 to the outer wall of the discharge ring 201. When a lot of solid waste drug accumulates in the discharge ring 201, the sealing block 101 is opened to complete the waste discharge.

[0018] Specifically, the drive assembly includes an extrusion cylinder 5, a discharge cylinder 8, a centrifugal motor 9, a drive gear 10, and a driven gear 11.
