Basket type extraction tank and basket thereof

Abstract

The invention provides a basket type extraction tank and a basket thereof. The basket type extraction tank comprises a tank body, the basket and a pressing piece, the tank body is provided with a bottom wall, a side wall and a top cover, the bottom wall is provided with an outlet, the side wall is provided with an inlet, an upper side wall sealing ring and a lower side wall sealing ring are formed in the side wall, and the top cover is connected with the side wall through a switch and a locking mechanism; the number of the baskets is more than two, the baskets are vertically stacked in the tank body, each basket is provided with a basket bottom, an outer ring wall, an inner ring wall and a basket cover, the basket bottoms, the outer ring walls and the inner ring walls are all provided with meshes, the inner ring walls and the outer ring walls are connected through reinforcing ribs, and the inner ring walls form drainage holes which are through up and down. The pressing piece is matched with the side wall, the upper side wall sealing ring and the lower side wall sealing ring, the vertical basket can be limited or tightly pressed from the top of the vertical stacking basket, the interior of the tank body is physically and forcibly divided into a plurality of areas, and the problem that when a traditional basket type extraction tank is used for extracting plants, the extraction efficiency is high is solved. And due to buoyancy, the basket integrally floats upwards to cause failure of the sealing ring.

Description

technical field [0001] The invention relates to a device for extracting traditional Chinese medicinal materials, in particular to a basket-type extraction tank and a basket thereof which have good adaptability to situations in which the density is lower than that of a solvent. Background technique [0002] Basket extraction tanks are widely used in food, medicine, and daily chemical industries. Its basic principle is to use a net-shaped basket around, at the bottom, and in the middle to hold materials to be operated, such as Chinese medicinal materials. [0003] The process of the basket entering and exiting the tank is usually through the hook grabbing the middle of the top of the basket to enter and exit the tank. The bottom of the drug basket is closed with the support frame in the extraction tank, so that the whole system is divided into three independent parts, namely the bottom of the tank, the inside of the basket and the outside of the basket, and these three parts ...

AI Technical Summary

Problems solved by technology

[0004] First, when the density of the extracted / cleaned substance is lower than that of the solvent, the basket will float, causing the three isolated cavities to be opened, and the solvent in the circulation will perform inefficient external circulation without passing through the medicinal materials;

[0005] Second, when the density of the extracted / cleaned substance is lower than that of the solvent, the extract in the basket will drift out of the basket, causing blockage of the circulation pipeline;

[0006] Third, when the density of the extracted / cleaned material is lower than that of the solvent, under the action of the external circulation, the multi-layer stacked baskets will shift between the baskets, making it difficult to take out the baskets;
