Abstract

This invention relates to the machining of materials. The purpose of the invention is to increase the processing efficiency of liquid materials in a disintegrator by combining mechanical activation with acoustic. The disintegrator comprises a housing 3, rotors 2 with fingers arranged in concentric rows, of a feed vessel 7 communicated with the interrotor space by axial and radial channels in the rotor. The fingers of the nearest row of the second rotor are located with a gap to the first, equal to 0-1 / 4 of the diameter of the radial channel. Thus, during the operation of the disintegrator, the liquid under the action of centrifugal force enters the interrotor space through the channels in the rotor and fingers. The liquid jets emerging from the radial channels on the outside of the fingers are interrupted by the fingers of the other rotor, and this results in the excitation of acoustic oscillations. 2 Il. , 3 / O 00 00 o o o

Description

The invention relates to the machining of materials and may find application in the building materials industry, the chemical and food industries.

The purpose of the invention is to increase the processing efficiency of liquid materials in a disintegrator by combining mechanical activation with acoustic.

Figure 1 shows the disintegrator, a General view; Fig. 2 is a flow pattern for jets from channels.

The disintegrator consists of electric motors 1, rotors 2 enclosed in housing 3 with an outlet 4. Hole 5 serves to allow air, liquids, or mineral materials to enter the inter-engine space. The rotors are placed fingers 6. From the supply tank, for example tank 7, the fluid through the channels 8 and 9 and the axial channels 10 can flow into the fingers 11, having radial channels 12, located on the outer side of the fingers 11, in the interrotor space.

The radial clearance between these fingers and the nearest row of fingers of the other rotor is equal to or less than 1/4 of the diameter of the radial channels in the fingers.

The size of the gap is determined from the condition of the effect of the barrier on the outflow of jets, based on the equality of the cross-sectional areas of the fluid in the jet and along the barrier.

,

where d is the diameter of the radial channel in the finger;

L is the thickness of the fluid layer along the barrier (the other finger). j

From formula A - and recommended

as the maximum allowable gap between the rows of fingers.

The device works as follows.

When processing materials, such as the oxidation of tar when the rotors rotate, the tar under the action of centrifugal force arising in the rotor channels, pulls out of tank 7 through channels 8 and 9 and axial channels 10 and through radial channels 12 into the micro-space where air entering through the hole 5. When

The output of tar from the radial channels 12 of the jet is interrupted when the rotors rotate with the next number of fingers, creating pulsations that are the source of acoustic oscillations. Ripple frequency

determined by the number of fingers and the speed of rotation of the rotors. Under the action of acoustic oscillations, better dispersion of tar occurs, viscosity decreases, and sound activation of tar occurs, and, consequently, an increase in the efficiency of tar oxidation in the disintegrator.
