Description

The utility model refers to devices for electromagnetic processing, such as liquids or solids, for example, when conducting research, etc.

A device for electromagnetic processing of objects, for example, water, is known, which contains a series-connected power supply source, a generator unit and an antenna made in the form of a solenoid with a free end attached to a pipe with water, and the generator unit contains a two-phase generator of electrical oscillations, the signals of which are of complex shape pass into the solenoid antenna and act on the water flowing through the pipe (see patent GB No. 2312635, class C02F 1/48, publ. 05.11.1997).

However, this device is not efficient enough to treat water with an electromagnetic effect when used on pipelines made of magnetic materials (metal). The electromagnetic field generated by the coil-type radiator causes parasitic magnetization of the pipeline and has a low penetrating effect into the processed liquid.

The closest to the utility model in terms of the technical essence and the achieved result is a device for electromagnetic processing of objects by induced fields, which contains an electrical circuit, including a power supply unit, an impact generator connected to the electrical circuit, and an electromagnetic energy emitter (see patent RU No. 2089513, class C02F 1/48, publ. 09/10/1997).

However, in this device, the generated electromagnetic field has a low penetrating effect with a narrow bandwidth, which limits the scope of this device.

Known material and method for producing metal-polymer composite materials based on nanoscale particles intended for use in radio equipment. Polyethylene or polypropylene, etc., are selected as the polymer, and metals are selected as metal-containing compounds (RU 2506224, В32В 27/00).

The technical result consists in the fact that it is possible to enhance the penetrating effect of radiation by providing the effect strictly within the bandwidth (effectively transmitted ESPH frequency band). This is ensured by the fact that the selection of parameters is not needed, but one of the optimized modes is immediately set.

A distinction is made between the absolute bandwidth: 2Δω = Sa and the relative bandwidth: 2Δω / ωo = So. In this technical solution we are talking about absolute.

The technical result is achieved by a utility model due to the fact that an autonomous device for electromagnetic processing of objects by induced fields contains a battery-powered electric circuit located in a multilayer protective case made of a polymer-metal composite material, including an electromagnetic energy emitter made in the form of an antenna and inductance coils connected by the output to the microcontroller with an indicator of the mode selection and a read-only memory (ROM) unit connected to an impact device configured to register the output signals of objects and connected to the microcontroller with the ability to exchange and transmit information from the microcontroller and ROM, while the microcontroller is connected to the output a signal generating unit, which is connected by its output to an emitter of electromagnetic energy.

A significant difference of this device is its autonomy (battery use) and the absence of a measuring channel, due to the addition of optimized operating modes. From which the user can choose what he needs. All this not only makes the device compact, but most importantly, the absence of a measuring channel and the addition of connecting optimal modes increases the penetrating ability of a given radiation (and allows it to be used by a person without additional measurement skills).

During the operation of the utility model, the impact is carried out within that known frequency range where the amplitude-frequency characteristic (AFC) of the claimed radio technical device is sufficiently uniform in order to ensure the transmission of signals without significant distortion of the shape. This effect is associated with the fact known from the prior art that the main signal energy is concentrated in the ESP (at least 90%). This frequency range is established for each signal of the claimed device by experimentally simple selection at the operator's workplace.

The bandwidth (GOST 23611-79 Electromagnetic compatibility of radio electronic means) is expressed in frequency units (for example, in hertz). Since in radio communication and information transmission devices, the expansion of the bandwidth allows you to transfer more information

Uneven frequency response characterizes the degree of its deviation from a straight line parallel to the frequency axis and is expressed in decibels. Reducing the frequency response unevenness in the band improves the reproduction of the transmitted signal shape.

The choice of material has an important influence on the above characteristics: for example, composites with a metal matrix, for example, filled with fine particles that do not dissolve in the base metal (dispersion-strengthened composites) additionally stabilize the characteristics of the contour, and also make it possible to significantly reduce the mass of the joining elements of structures due to the greater the strength of a metal matrix in comparison, for example, with a polymer one, and the manufacturability of processing composites with such a matrix (the possibility of using threaded connections, etc.).

Example of device operation

For the antenna used in the utility model with the geometry of the golden section, the bandwidth (as you know, this band depends on the type of antenna and its geometry) - the frequency range at which this antenna works effectively - the vicinity of the central (resonant) frequency. Therefore, in practice, the bandwidth has usually been set to a given standing wave ratio of 2.

In the declared utility model, an oscillatory circuit is formed, since during the transmission of certain signals, the high-frequency current in the antenna consists of several currents of different frequencies. Electromagnetic waves propagating from the antenna are of the same complex nature.

At the same time, the choice of material for the body of the entire device is also important. It is known that usually several different materials are used for the production of cases for electronic devices:

Plastic + metal

Plastic + glass

Plastic + ceramics

Plastic + rubber

etc.

However, the authors carried out the necessary calculations, computer analysis and subsequent modeling, taking into account the ongoing processes of impact on objects (including living organisms), which made it possible to optimize the design of the device and the case, taking into account the characteristics of the selected material. As such a material, it is possible to choose a composite based on a polymer (polyethylene, polypropylene, phenolic, fluoroplastic, polyurethane) with the addition of metals or their compounds adopted in these products, since polymers are widely used in electrical engineering, electronic devices, and various equipment, where it is very important to have materials with certain electrical characteristics. Such characteristics, the value of which may need to be adjusted, include electrical conductivity, dielectric strength, dielectric constant.

There are no restrictions on the use of polymers as a binder in the creation of electrically conductive polymeric materials. These can be rigid thermo- and thermosetting plastics with a constant shape of the product or rubber-like materials with a shape that changes under loading, i.e. materials capable of large reversible deformations.

Powders of iron, copper, aluminum, nickel, tin, bismuth, cadmium, palladium, and in some cases, silver and gold are used as fillers. The size of metal particles is (1-3) × 10 ^-7 m. The mechanism of electrical conductivity of polymers depends on the content of metal particles, which can reach 90% by volume.

Additionally, it is possible to use carbon black and graphite, both in the form of powders and in the form of fibers and fabrics. In the latter case, electrically conductive materials with high strength and anisotropic properties are obtained.

The choice of the band is determined in this way: when the circuit is affected by electromotive forces (emf) of different frequencies, the strongest oscillations are obtained when the emf has a resonant frequency or a frequency close to it. And with a significant deviation of the frequency of the external emf from the resonance value, i.e. when the circuit is out of tune with respect to the frequency of the external emf, the amplitude of the oscillations turns out to be relatively small.

We can say that each circuit passes vibrations well within a certain frequency band located on both sides of the resonant frequency. This is the specified bandwidth of the Ppr circuit, which is conventionally determined from the resonance curve at the level of 0.7 of the maximum value of the current or voltage corresponding to the resonant frequency.

In other words, it is believed that the circuit passes oscillations well when their amplitude decreases by no more than 30% compared to the amplitude at resonance.

Example.

The claimed device has a circuit tuned to a specific frequency.

Element base of the device:

microcontroller of new generation, with high speed of data processing and provision,

battery, which makes the device autonomous,

an indicator that allows you to select one of several optimized modes, since ready-made modes are used, which allows you to make the device compact,

ROM - read-only memory - a microcircuit in the memory of which the recorded signals are stored.

The user selects the operating mode of the devices on the indicator, which corresponds to the list of stored signals.

These signals are subtracted from the memory microcircuit and fed to the emitter (the "golden section" antenna and the inductors form the emitter of electromagnetic energy). The golden ratio is an antenna made on a printed circuit board.

When turned on, the effect of an electromagnetic pulse occurs when the controlled signals of the triangle shape are generated. When exposed to a frequency fo = 2000 kHz and a loop attenuation of 0.01, and then, based on the above technical information in the prior art, the specified bandwidth is determined as 0.01 * 2000 kHz = 20 kHz. The housing made of a composite plastic with metal additives provides a positive effect on maintaining a stable bandwidth, it is controlled when exposed to a microcontroller with a reflection of indicators on the indicator with the possibility of making adjustments to the effect of a controlled signal, depending on the degree of impact.

The recorded signals are stored in ROM 3, and controller 2 reads from ROM 3, depending on the selected operating mode of the device, determined by the operator using indicator 1.

A command from controller 2 is transmitted to the block of generating signals and, depending on the selected mode, signals of a given shape are generated: sinusoidal, sawtooth and others with the required frequency and amplitude.

By means of an inductor 4 and an antenna (golden section) 5, the effect is carried out.
