SU860868A1 - Centrifugal liquid cleaner - Google Patents

Abstract

A centrifugal liquid scrubber comprising a hollow vertical shaft fixed without movement in a base and provided with a liquid inlet and outlet both communicating with the corresponding chambers of a cylindrical rotate mounted on said shaft and comprising a bushing arranged in the relation coaxial with the hollow shaft and having a spiral wound band whose adjacent turns contain separators arranged radially one after the other, parallel to the hollow shaft and which, in conjunction with the band, form gaps for the passage of the liquid, and rotors or impellers installed on the ends of the bushing and constructed in the form of discs that have ribs attached to hold the edges of the spacers.

Description

The gaskets 12, together with the turns of the tape 11, form a series of vertical channels 13 for cleaning the fluid. The lower and upper impellers 14, 15 are pressed into the sleeve 10. The upper part of the impeller 14 is a disk 16 with radially arranged fins 17, and the lower part is made in the form of a pulley 18. Radial channels 19 formed by ribs serve to supply liquid to the vertical channels 13 17 of the lower impeller 14, disk 16 and not with one end of the helix 11.

The tops of the impeller 15 are made in the form of a disk 20 with radially arranged ribs 21. Radial channels 22, formed by the perforated end of the spiral tape 11, disk 20 and the edges 21 of the impeller 15, serve to drain the purified liquid from the vertical channels 13.

The rotor 4 is closed by a housing 23.

The cleaner works as follows.

The rotor 4 is rotated through the pulley 18. The liquid to be cleaned enters the cleaner through the nozzle 5. The direction of flow is indicated by arrows. Through the holes 9 in the hollow axis 1, the liquid falls into the radial channels 19 and from them into the vertical ones. The most advantageous velocity distribution in the channels 13 of the helix is the distribution according to the law

- const,

g

where V is the velocity of the fluid in the channel;

and g is the radius of its location, since only with such a distribution of velocities is the same degree of purification ensured in each vertical channel and therefore the greatest efficiency of the cleaner.

In the proposed cleaner, the distribution of speeds in the vertical channels is achieved by the fact that the impeller disks are made and reinforced in such a way that the distance between them and the ends of the tape helix is referred to as

where / 1 is the distance between the disk of the lower impeller and the bottom end of the belt;

1-2 — distance between the disk of the upper impeller and the upper end of the tape helix;

R is the maximum radnus of the helix; g is the current radius of the helix;

Go - the minimum radius of the helix. The particles of contamination entering the liquid into the vertical channels 13 under the action of centrifugal force are deposited on the walls of the channels, and the degree of purification of the liquid in all channels is the same.

The purified liquid through the radial channels 22 enters the device 7 for draining the liquid, and from it through the pipeline 8 and 1 of the pipe 6 to the consumer.

The proposed centrifugal cleaner at 800 rpm, rotor diameter of 160 mm and a height of 200 mm provides cleaning of liquids from all abrasive and metal particles with a size of up to 1 micron with a capacity of up to 40 l / min.
