Description

The invention relates to the magnetic treatment of fluid media, in particular to modular devices for the magnetic treatment of substances that can change the physicochemical properties of substances, and can be used to magnetize liquids, bulk materials, agricultural seeds. crops and applied in industry, agriculture, medicine, everyday life, etc.

State of the art

A device for magnetizing water, comprising a housing made of diamagnetic material, permanent magnets arranged in grooves uniformly around the circumference of the housing, the magnets being magnetized along the transverse side and mounted in grooves with the longitudinal side parallel to the axis of the housing along its entire length with alternating poles around the circumference of the housing N, N, S, S (see A.S. USSR No. 1068395, class C02F 1/48).

Design flaws - for the installation and repair of the apparatus, it is necessary to stop the process, disassemble a part of the pipeline, which leads to additional monetary losses.

A device is known comprising a ferromagnetic housing with a working channel, a permanent magnet system with an axial magnetic field in the working channel, mounted on the outer surface of the housing, and a ferromagnetic casing tightly enclosing the magnetic system. A coaxial metal rod is placed in the working channel. Streamline nozzles are fixed on the rod, which are combined with antinodes of the magnetic field in the working channel (see US Pat. RU No. 2208591, class C02F 1/48).

Design flaws - the working gap is greatly narrowed, the number of working modules can be more than two, which accordingly increases the resistance to the flow of the processed substance.

The closest in technical essence to the proposed design and adopted by the authors for the prototype is a device for magnetic processing of a substance, which consists of magnetizing coils, magnetic circuits and poles covering a pipeline, while the magnetic circuit, magnetizing coil, steel pipe form four magnetic modules, each of which is fastened non-magnetic plates and contains poles. The poles at the points of contact with the pipe have samples of ferromagnetic material with a depth of not more than the smallest side of the contact area of each pole (see US Pat. RU No. 2223234, class C02F 1/48).

The disadvantages of the device: a current source is required, a small contact area of the magnetic poles with the pipeline and, as a result, the lack of rigidity of the apparatus mounting on the pipeline; lined magnetic circuit complicates the assembly, manufacturing technology and installation of the magnetizing coil.

Disclosure of invention

The technical result is achieved using a modular apparatus for magnetic processing of matter, containing magnetic modules mounted on the pipeline, the poles of which cover the pipeline, characterized in that the magnetic modules are made of permanent magnets, each of which has two oblique poles of opposite polarity, adjacent magnets are connected by the same poles without an air gap between them, the angle of each pole of the magnet conjugated with the pole of the adjacent magnet is 45 °, and the air gap between the magnet and the surface of the pipeline is not more than 0.1 mm.

Brief Description of the Drawings

The drawing shows a modular apparatus for magnetic processing of matter, General view.

The implementation of the invention

The modular apparatus for magnetic processing of matter consists of four identical magnet modules 1 made of a permanent magnet, each of which has two oblique poles 2, which coincide with the magnetic poles of the magnet N and S. The angle of the pole 2, conjugated with the pole of the neighboring magnet, is α = 45 °. At the junction, two adjacent poles 2 form an oblique joint 3. The gap of the joint 3 between the corners of the poles is δ = 0.

Magnets-modules 1 are installed directly on the pipeline 4, completely wrapping it around, and are fixed on it with a metal clamp 5, consisting of a tape (not indicated), a loop (not indicated) and a tightening pin 6, all of which are made of non-magnetic metal. The working area 7, in which there is a direct effect on the processed substance, occupies the entire cavity of the pipeline 4.

Since the module magnets 1 are mounted directly on the pipe 4, an additional air gap is formed between the magnet module 1 and the pipe 4 due to surface irregularities in the pipe 4, the value of which is equal to λ.

Each magnet module 1 creates four magnetic fluxes (in the drawing, all magnetic fluxes are represented by the middle lines): Ф ₁ - main magnetic flux, Ф ₂ - saturation stream of part of the pipeline 4, Ф ₃ - working flow (buckling stream) and Ф ₄ - flux scattering, which are directed from the magnetic pole S to the magnetic pole N.

A modular apparatus for magnetic processing of a substance works as follows.

The magnet module 1 creates the main magnetic flux Ф ₁ , which closes along the magnet, and the magnetic flux Ф ₂ closes along part of the steel section of the pipeline 4, as a result of which this part is saturated.

Magnets-modules 1 are arranged so that the magnetic poles of the same name - N and S, of neighboring magnets are nearby (alternating magnetic poles around the circle -NS-SN-NS-SN-), resulting in mutual repulsion of magnetic fluxes and, as a result, magnetic displacement flow F ₃ to the working area 7. This stream is called the working and affects the processed substance. The scattering flux F ₄ is useless and closes through the air.

When designing the apparatus for magnetic processing of matter, models with the same parameters of the permanent magnet but with different values of the angle α were calculated: α = 0 °, α = 15 °, α = 30 °, α = 45 °, α = 60 ° and α = 75 °. As a result of the calculation, the following maximum magnetic fluxes Ф ₃ and Ф ₄ were obtained:

- α = 0 ° -F ₃ = 52 mT, F ₄ = 105 mT;

- α = 15 ° -F ₃ = 97 mT, F ₄ = 214 mT;

- α = 30 ° -F ₃ = 113 mT, F ₄ = 309 mT;

- α = 45 ° -F ₃ = 153 mT, F ₄ = 561 mT;

- α = 60 ° F ₃ = 122 mT, F ₄ = 646 mT;

- α = 75 ° -F ₃ = 108 mT, F ₄ = 848 mT.

When the value of the air gap δ = 0 of the oblique junction 3 and the angle α = 45 ° of the oblique pole 2, an increase in the magnetic resistance between the poles 2 of one magnet module 1 results in an optimal redistribution of magnetic fluxes: the magnetic flux path Φ increases through the air ₄ , its value decreases due to the increase in magnetic resistance and thereby allowing to achieve the maximum value of the magnetic flux f ₃ in the working area 7.

The magnitude of the magnetic flux Φ ₃ also depends on the density of contact of the magnet module 1 to the surface of the pipeline 4, therefore, the value of λ should be no more than 0.1 mm.

The invention in comparison with the prototype and other known technical solutions has the following advantages:

- the use of permanent magnets allows you to abandon the current source;

- lack of consumption of electric energy;

- improving the technology of mounting the apparatus on the surface of the pipeline;

- the shape of the magnets-modules and their poles allows to achieve the greatest magnetic effect in the processing zone, and also increases the mechanical rigidity of the structure;

- simplification of the design.
