Description

ULTRASONIC REFLECTOR OF MECHANICAL IMPURITIES IN LIQUID

one

The invention relates to the field of construction and road engineering and can be used to grind up to hundredths and thousands of micron particles of mechanical impurities in the working fluid of the hydraulic systems of construction and road machines.

A known ultrasonic grinder of mechanical impurities in a liquid contains lower and upper disks located on the axis, placed in a cylindrical body, and a fitting for supplying liquid. However, with the help of these devices it is impossible to crush ultra-fine impurities.

In the proposed device for ultrafine grinding of mechanical impurities, the upper disk, on the lower base of which a triangular cross section is located, is provided with weights and is movable along an axis. In this case, the lower disk is made in the form of a conjugate truncated cone and cylinder.

The drawing shows schematically the proposed grinder.

It consists of a housing 1, a board 2, an axis 3 on which the upper disk 4 with the load 5 and the lower disk 6, the nozzle 7 and the aperture for the outflow of the treated liquid are located.

On the lower base of the upper disc, an annular tuck of a triangular cross section is made (the acute angle of the triangle, directed to the axis at an angle of 8-14 °, the second acute angle is 45 °).

An ultrasonic grinder is installed on the drain line of the hydraulic system of construction or road machines.

The grinder works as follows. The working fluid is supplied through fitting 7 and through hole a in axis 5 enters the cavity b. The upper disk 4 with the load 5 moves upward along axis 3, forming a gap with the lower disk through which the working fluid passes into the cavity b. The fluid hits the wall of the sweep, located at an angle of 45 °, changes its direction and hits the main flow, which leads to an intensification of the occurrence of ultrasonic vibrations.

The size of the gap between the discs is automatically adjusted depending on the flow rate of the working fluid.

In the cavity b, superfine grinding of contaminants takes place, after which the working fluid flows into the tank through the holes.

When the flow rate of the working fluid through the generator changes, it changes proportionally

the size of the gap between the discs 6 and 7. At the same time, the pressure of the working fluid in the cavity b remains constant and equal to 2 kg / cm, which ensures the automatic operation of the generator, independent of the flow rate of the fluid.

Subject invention

An ultrasonic grinder of mechanical impurities in a liquid, containing lower and upper disks located on the axis, placed in a cylindrical body, and a fluid inlet, characterized in that, for the purpose of superfine grinding of mechanical impurities, the upper disk, on the lower base of which is an annular thrust triangular section, provided with a load and made with the possibility of movement along the axis, while the lower disk is made in the form of a conjugate truncated cone and cylinder.
