Test instrument for liquid-solid extraction separation

Abstract

The invention relates to the technical field of liquid-solid extraction separation, and discloses a test instrument for liquid-solid extraction separation. The test instrument comprises a base and a rotating assembly, the inner wall of the top of the base is movably connected with the outer wall of the bottom of the rotating assembly, and the outer wall of the rotating assembly is movably connected with a limiting pipe. According to the test instrument for liquid-solid extraction separation, in the rotating process of the outer pipe, the reciprocating assembly also rotates along with the outer pipe, under the action of a limiting block, a connecting plate moves towards the opposite side, so that the limiting force of the connecting plate on the filter screen disappears, at the moment, a fixing plate moves under the action of an elastic rope, and a connecting column and a connector also move under the action of the elastic rope and generate pulling force on the filter screen; and when the pressed plate moves to the tail end of the limiting block, the pressed plate rebounds under the action of the constant-pressure rod, so that the connecting plate can generate explosive pulling force on the filter screen, solid substances on the surface of the filter screen are separated, and the effect of preventing the solid separation efficiency from being reduced due to accumulation of the solid substances is achieved.

Description

technical field [0001] The invention relates to the technical field of liquid-solid extraction and separation, in particular to a test instrument for liquid-solid extraction and separation. Background technique [0002] Solid-liquid extraction, also called leaching, uses solvents to separate components in solid mixtures, such as leaching sugars in beets with water, leaching soybean oil in soybeans with alcohol to increase oil production, and leaching active ingredients from traditional Chinese medicine with water It is called "percolation" or "leaching" to prepare liquid extract. However, in the process of solid-liquid separation, in addition to the above methods, the operation method of centrifugation and liquid extraction is often used. However, this operation method often exists Certain issues are mainly reflected in the following: [0003] When performing solid-liquid separation, the equipment will rotate, and under the action of centrifugal force, the solid matter will...

AI Technical Summary

Problems solved by technology

[0003] When performing solid-liquid separation, the equipment will rotate, and under the action of centrifugal force, the solid matter will adhere to the inner wall of the equipment. At this time, under the blockage of the solid matter, the export efficiency of the liquid will decrease sharply. As the operation progresses, The accumulation of solid substances will also increase, which will reduce the separation efficiency of liquids

[0004] Therefore, the demand for high-reliability products is imminent, so we proposed a test instrument for liquid-solid extraction and separation, which has the advantage of avoiding the reduction of solid-state separation efficiency due to the accumulation of solid substances, to solve the above problems
