Description

(54) CENTRIFUGAL LIQUID CLEANER

BACKGROUND OF THE INVENTION The invention relates to devices for separating liquids in a field of action of centrifugal el.

According to the main author. St. No. 332863 is a centrifugal fluid cleaner with a cylindrical rotor, completed with an insert in the form of a spiral, which provides an axial direction of fluid motion. In this case, the insert is made of a thin tape wound onto a sleeve with small gaps, fastened along the ends of the radial ribs.

In order to increase the cleaning efficiency, in the proposed cleaner, gaskets are installed radially and parallel to the rotor axis in each gap between the turns of the helix.

The drawing shows a liquid cleaner, a longitudinal slit.

The cleaner contained 1 pc mounted on a stationary hollow axis 1 on bearings 2 and 3 sliding the rotor 4 with the insert 5 in the form of a spiral, the impellers 6 and 7, respectively, the upper and lower; At the bottom of the rotor is mounted pulley 8.

An axis 1 disk 9 is installed on the axis 1, which serves to pump the liquid and at the same time is the upper bearing of the rotor 4.

In each gap, the helix / coywheel turns are mounted on a gasket J 5 pa,; 1, and a parallel to the rotor axis.

through the bolter 16, the holes 17 in the axis I and the channel A, and the removal of the refining part through the channel B, the central tube 18 and the attractor 19.

The work of the inspector is carried out in the following 5 ways.

The rotor 4 is rotatable from the drive through the pulley 8.

The cleaned fluid is supplied from the cleaner.

 16. Directional flow is indicated by arrows. Through the holes 17 in axis 1, the liquid enters

SUBMISSION-1 channel, and from it into the gaps 14 inserts 5.

Particles of contaminations, the density of which differs from the density of the O1 {Ffirma), fall into the gaps, and the action of deitroic force is deposited on the wall of the sand. A smaller width of the gap 14 allows an increase in the cleaning efficiency.

To achieve a uniform cleaning in each gap, the walls of the insert must be parallel to the thread. With small gaps and minimum tape thickness, this is ensured by installing calibrated gaskets.

The ratio relating the fineness to the gap width is

d

s are where: d is the diameter of the deposited particle;

co-rotational speed of the centrifuge;

V is the average fluid flow velocity in the insert gap considered;

M is the dynamic viscosity coefficient;

h is the width of the gap;

(e) is the difference between the mass densities of the particles of contamination and the liquid;

H is the length of the gap;

g is the radius of the gap relative to the axis of rotation.

The centrifugal cleaner described at 7500 r / rvfflH provides cleaning of impurities up to 1.5 µm with impurities with a capacity of 50 l / min and oils (hydraulic mixtures) with viscosity up to 20 centipuses with particles up to 3 µm with a productivity of 35 l / min.
