Abstract

Usage: the invention relates to equipment for the oil industry and can be used in the extraction industry. SUMMARY OF THE INVENTION 1 The extractor consists of a body with tubs (H), which are regularly located there, with grain bottoms and a rotor with radial partitions forming in each H chamber, an annular micelle collector under each chamber and an additional annular micelle collector under the discharge screw (M). In M, there are septa that have different heights to provide a cascade flow of micelles from section (C) with a lower concentration in C with a higher concentration. Each C is connected to irrigators of the corresponding H 2 Il

Description

The invention relates to equipment for the oil and fat industry and can be used in the extraction of oils from vegetable oil-containing raw materials.

The purpose of the invention is to intensify the extraction process by preventing disruption of the counterflow of miscella.

The extractor is equipped with an additional annular micelle collector with dividing partitions located in the lower part of the body under the unloading auger, and the dividing partitions have different heights to ensure the cascade flow of the micelle from the lower concentration section to the higher concentration section, and each section is connected through circulation means micelle collector and sprinklers of the corresponding vat,

Figure 1 shows the extractor, a general view; figure 2 - vat extractor, top view.

The extractor consists of river-shaped tanks arranged, the outer shell of which forms the housing 1. Inside each of the tanks there are coaxial shaft of the extractor 2, the inner shells 3 of the rotor with blades 4, which divide the rotor space into chambers.

The rotor is rotated by a drive 5. Each extractor tank has a grain bottom 6, provided with a sector cut, under which a shaft 7 is placed, passing through an annular micelle collector 8, located under the grain bottom 6, and the sector cut of a grain bottom of the downstream tank is offset from a sector cut of the upstream tank against the direction of rotation of the rotor.

It is connected to the discharge screw 9. Below the discharge screw 9 is an additional annular micelle collector 10, divided into sections by partitions 11. Each section of the additional micelle collector 10 is connected by means of pumps 12, pipelines and sprinklers 13 with a corresponding tank and its ring micelle collector 8. The upper tank is supplied with a feeder 14, and the lower tank is equipped with a sprinkler 15 for feeding solution l.

The extractor works as follows.

The material is loaded by the feeder 14 into the chambers of the rotor of the upper tank of the extractor, formed by the inner shell 3, the grain bottom b and blades 4. The rotor, rotating from drive 5 around shaft 2, moves the material to the sector cut of the grain bottom and the material is irrigated with micelle, supplied from the corresponding tank section of the additional annular micelle collector 10 by means of pump 12 and sprinklers 13. After passing through the layer of material, the micelle collects in the annular micelle collector 8 and flows into the same section of additional micelles of the sampling tank 10 The material extracted in the tank through the shaft 7 is poured into the underlying tank, where it is irrigated with a micelle with a lower than the previous concentration supplied by another pump 12 from the section of the micellar collector 10 corresponding to the tank. Thus, the material is gradually degreased from the top of the tank - down all the tanks of the extractor and after irrigation with a pure solvent through the irrigator 15 in the lower tank with a discharge screw 9 is taken out of the extractor. Micelles of various concentrations are collected in the corresponding sections of the additional annular micelle collector 10 and the cascade flow of the micelle from one section to the other through partitions 11 is possible only towards increasing the concentration of the micelle due to the different height of the partitions 11. The concentrated micelle itself, corresponding to the upper tank, is removed from the extractor section of the additional annular micelle collector 10 for further processing.

All working bodies of the extractor are separated from the atmosphere by a hermetic case 1, since the extraction is carried out with a solvent of hexane fractions.
