SU131703A1 - A device for decanting a liquid fraction in a column apparatus - Google Patents

Description

Patent No. 122440 describes a column diffusion apparatus for the continuous dehydration of beet chips or similar materials, having a paddle transporting organ and a similar organ in the lower part of the column, which serves to distribute the supply of chips to the transporting organ, and a device for expressing juice.

The proposed device is a modification of the device for decanting the liquid phase in the column apparatus according to patent No. 122440, allows to increase the expressed surface and to some extent adjust the flow of the juice-chip mixture using shields.

FIG. 1 shows the proposed device in section; in FIG. 2 - the same, with a modified fastening of flaps with scrapers.

in the column 1 of the diffusion apparatus in the space between the vane transporting body 2 and the wheel 3 distributing beet chips, perpendicular to the main shaft 4, one or more hollow perforated drums 5, which serve to express the liquid fraction, are radially fixed.

№ 131703

A sieve drum 5 is planted on a hollow shaft 6, which also serves to drain the squeezed juice through pipe 7. The hollow shaft 6 receives rotation from the electric motor 8 through a V-belt transmission 9.

In front of the screen drum 5 to the wall of the column / reinforced JO planted freely on the hollow shaft 6, behind which, in accordance with the properties of the juice-chip mixture, an area enriched with the liquid phase is formed, which facilitates straining it into the drum, through the screen material.

To clean the sieve surface of the drum 5 from the chips, scrapers 11 are used, which are fastened with staples 12 on a tubular rod 13 connected to the flap 10. For the same purpose, compressed air or water can be supplied to the inside of drum 5.

In order to radially rotate the shield 10 and adjust the slot for the passage of the juice-chip mixture, an arc slot is provided in the wall of the column for the passage of the fixing plate 10 of the bolt 15.

The flap 10 with the scraper 11 can be suspended suspended, independently of the sieve cylinder, by means of the plinth 16 with the bolt 17 passing through an ellipsoidal opening in the wall of the column.

The change in the position of the flap 10 in this case is made outside the column /.

The juice-strand mixture entering the apparatus, with the paddle wheel 3 being evenly distributed throughout the entire volume of the column 1, is fed to the perforated drums 5, by means of which the diffusion juice that is discharged from the apparatus through pipes 7 is discharged from the mixture.

The efficiency of the reel drums increases if their circumferential rotational speed is chosen somewhat higher than the flow of the juice-chip mixture flowing around them.

The waste material (pulp) is removed from the apparatus by the blades of the transporting body 2.

Subject invention

Claims (3)

1. A device for scaling the liquid fraction in column apparatus according to patent No. 122440, characterized in that, in order to increase the squeezing surface, the device is made in the form of radially mounted perpendicular to the main shaft of the trasporting organ, in the space between it and the distributor wheel, rotating hollow sieve drums behind shields provided with scrapers to clean the sieve drum surface. 2. The form of the device according to claim 1, characterized in that the perforated drums are planted on hollow shafts serving to drain the squeezed juice, and the shields with scrapers are loosely seated on empty shafts and fixed to the wall of the column. 3. A change in the attachment of the flaps with scrapers according to claim 2, characterized in that, with the aim of adjusting the gap between the flap and the drum, the flap is provided with a base with a bolt, with which it is attached to the wall through an ellipsoid hole regardless of the fixation of the sieve cylinder, the scraper is fixed with staples on a tubular rod connected to the flap.
