Embodiment Construction

[0042] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0043] Such as figure 1 As shown, it is an external reflux device of the centrifugal extractor. The device comprises a feed pipe 1 passing through the upper cover 2 and a solution collection chamber 7 communicated with the outlet of the feed pipe 1; The bottom of the collection chamber 7 is provided with a return pipe 10 and a small-flow phase liquid outlet device; the small-flow phase liquid outlet device consists of a small-flow phase liquid outlet pipe 9 and a short pipe inserted on the small-flow phase liquid outlet pipe 9 8 composition.

[0044] The reflux channel of the centrifugal extractor is a small-flow phase flow channel that flows from the feed pipe 1 into the solution collection chamber 7 and then returns to the inlet of the centrifugal extractor th...

Abstract

The invention relates to an external respective grade refluxing apparatus of a centrifugal extraction machine. The external respective grade refluxing apparatus comprises a closed solution collecting chamber; the upper side of the solution collecting chamber is fixedly provided with an upper cover, and a feeding tube connected with the small flow amount phase system outlet of the centrifugal extraction machine traverses through the upper cover and inserts into the solution collecting chamber; and the bottom of the solution collecting chamber is provided with a refluxing tube connected with the small flow amount phase system inlet of the centrifugal extraction machine and a small flow amount phase system liquid discharge device, and the inlet of the small phase system liquid discharge device is higher than the inlet of the refluxing tube. The apparatus is external, so the apparatus can be conveniently arranged at the liquid phase outlet end having a small flow amount and needing respective grade refluxing of the centrifugal extraction machine without any change of the structure of the centrifugal extraction machine, and has the advantages of stable running, great improvement of the extraction and separation effects, and good economic and social benefits.

Description

technical field [0001] The invention belongs to the field of solvent extraction, and in particular relates to an external reflux device of a centrifugal extractor. Background technique [0002] Centrifugal extractor is a fast and efficient liquid-liquid extraction equipment, which uses centrifugal force to realize the extraction and separation of liquid-liquid two-phase. The light and heavy phases enter the extractor from their respective inlets, flow downward through the gap between the lower shell and the drum, and enter the inside of the drum through the inlet at the bottom of the drum. The two-phase liquid is separated to achieve the purpose of separation. The separated two-phase liquids enter their respective collection chambers through different channels and flow out from their respective outlet pipes. Centrifugal extractors can be widely used in various fields such as hydrometallurgy, wastewater treatment, biology, pharmacy, petrochemical industry, chemical industry...
