Embodiment Construction

[0019] Depend on figure 1 , 2, 5, a horizontal spiral stirring leaching tank and its tank group, which includes a tank body 3 with a jacket 14, an agitator 7 connected to a drive mechanism 13, a feed inlet 6, a liquid inlet 11, and a steam outlet 4 , cleaning port 5, feed liquid outlet 15, etc. The tank body 3 is a horizontal cylinder with a jacket 14 or a tank with a U-shaped cross section with flange covers 2 at both ends, and the agitator 7 is formed by the passing method. The shaft 9 of the shaft hole of the blue cover 2, the support rod 8, and the ribbon-shaped spiral blades 10 and 12 are composed. The agitator 7 adopts a double-layer spiral ribbon blade structure. The outer spiral blade 10 turns and pushes the solid particles in the feed liquid from one end to the feed liquid outlet 15, while the inner spiral blade 12 turns and pushes the solid particles in the opposite direction. In addition to single-tank leaching, when a double-tank tank group leaching is set, the t...

Abstract

The invention relates to a horizontal stirring and countercurrent centrifugal leaching combination device and a leaching method thereof, belonging to the technical field of extraction and production of natural medicines. Among them, the agitator of the leaching tank adopts a double-layer ribbon structure, and the inner and outer ring ribbon blades turn over and push the solid phase particles in the feed liquid in the opposite direction, so that the liquid phase solvent can fully contact the surface of the solid phase particles for frictional elution. Choose the countercurrent centrifugal leaching method with appropriate crushing degree and lower heating temperature. Through multi-stage countercurrent leaching and sufficient solid-liquid separation between stages, the leachate from the previous tank can be used alternately as the solvent for the subsequent tank, saving a lot of solvents and reducing subsequent production load. , under the condition of maintaining and continuously creating the concentration difference, make the diffusion boundary layer thinner or update faster, so that the leaching production yield is high, the product quality is good, the cost is low and the economic benefit is good, and the equipment can be thoroughly cleaned and leached. Batch number and other GMP specification requirements.

Description

Technical field: [0001] The invention relates to a horizontal spiral stirring leaching tank and its tank group and leaching method, which belongs to the technical field of natural medicine (such as traditional Chinese medicine) extraction production, and is suitable for requiring low heating temperature, short heating time, reducing input and increasing output. And it meets the requirements of GMP standard requirements such as equipment can be thoroughly cleaned and products are divided into batches for leaching production of natural medicines. Background technique: [0002] The overflow tank (also known as the extraction tank) is the key to the extraction and production of natural medicines (especially traditional Chinese medicine). Because vertical leaching tanks are relatively simple to operate in the leaching process, most related companies in my country still widely use this type of tank. This type of tank with a jacket has a large length-to-diameter ratio, uneven heat...
