Centrifugal extractor

Abstract

The invention discloses a centrifugal extractor. The centrifugal extractor comprises a motor (1), a spindle (2), a flow guide part (56), a rotating drum (7) and a shell (8), wherein one end of the spindle (2) is connected with an output shaft (11) of the motor (1), and the other end of the spindle (2) is fixedly connected with the flow guide part (56); and the flow guide part (56) is fixedly connected with the rotating drum (7) and is positioned in the shell (8). Through the technical scheme, the rotating drum is indirectly connected to the spindle through the flow guide part and is indirectly driven to rotate by the spindle, so that when the spindle drives the rotating drum to rotate through the flow guide part, the extractor is not obviously vibrated even if rotating speed is high; therefore, ideal extraction and separation effects also can be achieved under the condition that the ratio difference of two-phase flow is large or the density difference of two phases is small.

Description

technical field [0001] The invention relates to a centrifugal extractor, in particular to a liquid-liquid two-phase centrifugal extractor. Background technique [0002] As an efficient and fast extraction technology, centrifugal extraction technology is widely used in fields such as hydrometallurgy, medicine, wastewater treatment, fine chemical industry, food, plant component extraction, and military affairs. The existing centrifugal extractor mainly includes a motor, a main shaft, a bearing, a bearing seat, a guide part, a drum and a casing, the main shaft is connected to the bearing seat through the bearing, and one end of the main shaft is connected to the motor The output shaft of the main shaft is connected, the other end of the main shaft is fixedly connected with the drum, and the guide part and the shell constitute the heavy phase inlet, the light phase inlet, the heavy phase outlet, the light phase outlet, the mixing chamber, the heavy phase guide flow path and lig...

AI Technical Summary

Problems solved by technology

[0003] In the above-mentioned existing centrifugal extractor, since the main shaft is directly connected with the drum, when the main shaft drives the drum at the end to rotate at a high speed, the centrifugal extractor will vibrate. The rotating speed of the drum makes the mixing and separation effect of the light and heavy phase not good enough, especially when the phase difference between the light phase and the heavy phase is relatively large (that is, the proportion of the light phase and the proportion of the heavy phase differ greatly. Below) or when the density difference between the two phases is very close, it is difficult to achieve the ideal extraction and separation effect
