SU389850A1 - THE METHOD OF ULTRASOUND CLEANING - Google Patents

Description

The invention relates to an ultrasonic cleaning technique used in many areas of the industry and, in particular, in the metallurgical industry - when removing contaminants formed in the process of rolling production on the surface of finished products, or in the machine industry in the inlet areas. depreservation of pipe and profile rolled products.

Methods are known for the ultrasonic cleaning of articles of tila pipes transported in an ultrasonic field formed by at least two transducers.

The drawbacks of the known methods are the low cleaning efficiency - due to the fact that the ZON is the most intense effect of ultrasound on your floor is not in the same focal area on the surface being cleaned.

In order to increase the cleaning efficiency of the method that is being preliminarily applied, the ultrasonic field is focused in 01. The limited surface area of the product is shifted and this focal area is moved along the treated surface.

In order to move the focal area over the surface to be treated according to the proposed method, product th) is placed in the ultrasound field of the battery of transducer blocks installed along the product being cleaned, each of which focuses

fluctuations on (the top of the product being processed in the region, with a displacement relative to the focal areas of the other blocks.

In addition, the ne / displacement of the focal region along the surface being processed is carried out by means of relative displacement of the products | LI and transducer block relative to the contour of the surface processing being processed.

On . 1 shows a nerve installation option. For cleaning that implements the proposed method; in fig. 2 is a section along A-A in FIG. one; in fig. 3 is a section along BB in FIG. I; in FIG. 4 shows the second version of the set I for cleaning, a section along the vertical plane; on fig. 5 shows a section along BB-a, and FIG. four.

Test Results Offer. method on the first version of the installation.

Of the six magnetostrictive transducers / type ПМС-6-2: 2 with flat 1 and 1, I emit a dimy plate 2 I assemble two closed ring systems, each of which has the shape of a trihedron, thus formed

In the internal cavity 3, the focal area 4 of each of them was shifted relative to the irodol axis 5 of the object being processed 6, 1 anrimer of the pipe. The transducer systems are mounted on the same axis 5 in the bath 7, filled with water, with one turn from O. Relatively

the other is 180 °, then their focal areas are evenly distributed on the surface of the tube 6 placed in the internal cavity of 3 systems. When using more systems of converters, the angle of spread is 2

This is defined by the ratio a, where

n is the number of systems. Magnetostrictiol transducers operate on a UM1-25 ultrasonic generator. Your equipment is equipped with a mechanical mixer, all the pipes being machined with a speed of 1 m / min, which corresponds to the Begin time of cleaning - 18 sec.

Stainless steel pipes diaprol 10-165 mm are tested with a machine thickness of 0.2-2 mm, the water temperature in the pitch is 18-25 ° C.

Tubes 6, previously seeded to obtain a visible layer of sludge, are fixed on a conveying device and move through the internal cavity of 3 transducer systems U operating in the operating mode.

Direction of the displacement of the pipe 6 along the aaaa arrow 5. Due to the impact of water in each system {Transducers /, the process of cleaning a part of the surface of the pipe 6, on which the vibrating oscillators are focused, takes place. After passing through both systems, the entire pipe 6 surface is cleaned. To eliminate possible errors, coitrol sampling of pipes through the first system of transducers is made along their transport compared to pipes that have passed through both systems. The quality of cleaning is controlled by the cleaning of the surface. Pipes that have passed through only the first generator conditioner system have been cleaned with one old one, which faces the focal area of the system; after passing through 5 (the second system clears the entire surface of the pipe.

The test results of the proposed method on the second version of yicTainoiBiKa.

The object to be cleaned for cleaning, 9, for example, pipe rolling, is placed in the inner cavity 10 of the ring system in the form of a polyhedron of six maps of the most tricky recipients 11 of the PMS-6-122 type with flat 1 and diaphragms 12, each mapnotoshtshionny radiator with a diaphragm. Replen on hinges 13, the axes 14 of which are installed parallel to the longitudinal axis 16 of the system in the myogrannum farm. Focal area 16 is formed in B1 internal proshosti

10 of the polygraphic system on the surface of the object to be cleaned 9, and the mounting system. Vadane 17, filled with water with a temperature of 18-25 ° C. Magnetostrictive emitters 11 are powered by an yMI-i25 ultrasonic generator. Vania is equipped with a mechanical drive for moving the rolled pipe 9.

Stainless steel pipes 9 with a diameter of 10-165 mm with a wall thickness of 0 mm pre-seeded to obtain a visible layer of slime are fixed on a transporting device and transferred through the internal cavity 10 of the transducer system operating in the operating mode. The movement speed is 1 m / min, which corresponds to a cleaning time of 18 seconds. In this case, the emitters / / are rotated in such a manner that the resulting focal area moves along the contour of the surface of the pipe 9, thereby cleaning it. Quality of cleaning is controlled by tamponation of the cleaned surface. To eliminate possible errors, control and | tests are performed to focus the ultrasonic vibrations on the geometrical axis of the system.
