Description

(54) EXTRACTOR

one

The invention relates to devices for carrying out extraction processes in a solid-liquid system.

A solid-liquid extractor is known for containing a horizontal rotary drum in which the transfer conveyor is arranged with flattened and coils dividing the drum into sections, perforated buckets and flow-through devices for liquid and solid material.

In a known extractor, a mixture of a liquid and a solid body at the time of its arrival in the section of the transporter is not homogeneous, which inherently reduces the intensity of the process.

The purpose of the invention is to intensify the extraction process.

This goal is achieved in that in each section between axes of the transporter, axial screens are installed with liquid passages located along the perforated wall, which is the bottom of the bucket, at the entrance to the next section. The screens are made in the form of perforated partitions, the total flow area of which increases from Pernferia to the axis of the drum. In addition, the screens are vyoliene in the form of a layer of chains and but the periphery are solid.

FIG. 1 shows a device, irodol); in fig. 2, 3 - section along A-A in FIG. 1 (options); in fig. 4 - device (va; m: ant), longitudinal section; in fig. 5 is a section: according to BB in FIG. four.

A spiral conveyor 2 is placed in the horizontal drum of the device. It is made in the form of consecutive continuous turns 3 arranged strictly one meter and connected with flat and inclined partitions 4. The turns of the conveyor divide the drum into sections with perforated buckets 5 for lifting hard materials. The bases 6 of the collet are pairwise connected by an axial screen 7. In the central zone of the drum 1, two rows of inclined channels 8 and 9 are provided for directing solid particles raised by the BOSCH 5 to a section of the same row.

The device works as follows.

The solid is released from the bucket 5 if it is in the upper part of the drum, B section 10 through channel 8, B and the left part of the drum. The part of the solid substance, which is guided by the solid continuous walls 4 of the conveyor 2, moves together with the liquid in the direction opposite to that indicated by arrow B, and becomes the section section. A portion of the solids rises during the next half turn of the drum (180-360 °) with a section 11 sweep. The process then proceeds cyclically.

When a solid enters the lower part of the drum, for example, the lower part of section 11, the liquid enters there too. During the half-turn of the drum, this liquid is distributed in section 11 together with solids but its width, and after a turn of 180 ° solids are lifted by bucket 5 from section 11, which then passes to the bottom of the drum. The liquid is separated from the solid, passes through the bottom of the bucket 5, encounters another part of the solid vegetation, and moves during the other half-turn of the drum in an annealing movement of the screws. At the beginning of the next drum rotation, the path of the fluid is repeated.

To evenly distribute the liquid with respect to the solid matter with which it will be found in the new section, as well as to close: the fluid flow into the new section along the bottom of the bucket 5, axial screens 12 are installed in each section between turns 3 of the conveyor 2.

The screens 12 are made in the form of hollow perforated sheets located axially between two successive turns 3, parallel to the base 6 of the bucket 5 and radially relative to the peripheral wall of the drum 1. The edges of the solid partitions 13 connect the screens 12 to the axial screens 7.

The total cross-section of the screens increases from the periphery of the drum 1 to its axis. The screens can be made along the periphery with a solid part 14 adjacent to the peripheral wall of the drums 1, beyond which the layer of foam 15 begins. Due to this design, a delay can be made between the beginning of the flow of a row and the moment the liquid accumulated at the back of a private part of the country flows into the corresponding section of a different row.

In the device (see Fig. 4), the direction of rotation of the drum is shown by arrow G; Double spiral worm transnorter, formed by a series of continuous diametrically located and having cut-outs of recessor 13, and connected by inclined solid non-rebuilding 16, provide for the non-transfer of solid barriers 1 in the direction of arrow D. , as well as dental buckets 5, divide the sections defined by the spirals into two rows of cells in which the solid is in contact with the liquid.
