Description

РЕЗОНАНСНО-ВОЛНОВОЙ КЛАССИФИКАТОР  RESONANCE WAVE CLASSIFIER
Устройство относится к области классификации сыпучих материалов и может быть использовано перерабатывающими предприятиями. The device relates to the field of classification of bulk materials and can be used by processing enterprises.
Известно устройство, для сортировки сыпучих материалов, которое содержит два генератора колебаний, укрепленных на стенках укрепленных на стенках корпуса, подвешенного горизонтально на тросовых подвесках (см а. с. СССР N 264049, кл. В07В1/36, 1968г.)  A device is known for sorting bulk materials, which contains two oscillation generators mounted on the walls mounted on the walls of the housing, suspended horizontally on cable suspensions (see a. S. USSR N 264049, class B07B1 / 36, 1968).
При работе генераторов создаются круговые колебания корпуса и транспортирование с просеиванием материала, находящегося на просеивающих поверхностях.  During the operation of the generators, circular vibrations of the casing and transportation with sieving of the material located on the sieving surfaces are created.
Недостатком такого устройства является то, что вибраторами создаются круговые или весьма близкие к ним колебания и материал на просеивающей поверхности для продвижение по горизонтальной плоскости подбрасывается, что связано с большими энергетическими затратами.  The disadvantage of this device is that the vibrators create circular or very close vibrations to them, and the material on the screening surface is thrown up to move along the horizontal plane, which is associated with high energy costs.
Этот недостаток преодолен в другом известном устройстве, содержащем корпус, просеивающее устройство, установленное с наклоном внутри корпуса и пару генераторов колебаний, закрепленных на стенках корпуса и кинематически соединённых с просеивающим устройством,  This disadvantage is overcome in another known device comprising a housing, a sieving device installed with an inclination inside the housing and a pair of oscillation generators mounted on the walls of the housing and kinematically connected to the sieving device,
(см. Патент РФ е2069590, кл. В07В1/40, 1992г.)  (see RF Patent e2069590, class B07B1 / 40, 1992)
Данное устройство по технической сущности и достигаемому результату наиболее близко к предложенному и, поэтому, принято за его прототип.  This device by technical nature and the achieved result is the closest to the proposed and, therefore, taken as its prototype.
Согласно известному техническому решению резонансно-волновой классификатор содержит, установленный на подвесках корпус, внутри которого наклонно в сторону движения материала подвешено просеивающее устройство в виде короба с просеивающей поверхностью в виде сетки. По бокам короба под одинаковым углом к его продольной оси закреплены генераторы колебаний, работающие в противофазе, с возможностью направления колебаний под одинаковым углом к продольной оси короба в плоскости просеивающей поверхности. При работе устройства генераторы колебаний включают в противофазный режим. При этом они создают зигзагообразное движение материала без подбрасывания по просеивающей поверхности. Это снижает затраты энергии. According to a known technical solution, the resonant wave classifier comprises a housing mounted on suspensions, inside of which a screening device in the form of a box with a screening surface in the form of a grid is suspended obliquely in the direction of movement of the material. Oscillators operating in antiphase are fixed on the sides of the box at the same angle to its longitudinal axis, with the possibility of directing vibrations at the same angle to the longitudinal axis of the box in the plane of the screening surface. When the device is in operation, oscillation generators are turned into antiphase mode. At the same time, they create a zigzag movement of the material without tossing along the screening surface. This reduces energy costs.
Недостатком известного устройства является его низкая эффективность, обусловленная образованием застойных зон на просеивающей поверхности.  A disadvantage of the known device is its low efficiency, due to the formation of stagnant zones on the screening surface.
Техническим результатом разработки является повышение эффективности устройства.  The technical result of the development is to increase the efficiency of the device.
Указанный технический результат достигается тем, что резонансно- волновой классификатор, содержащий корпус, просеивающее устройство, установленное с наклоном внутри корпуса и пару генераторов колебаний, закрепленных на стенках корпуса и кинематически соединённых с просеивающим устройством, дополнительно оснащен частотными преобразователями, расположенными вне корпуса и электрически соединёнными с генераторами колебаний, генераторы колебаний закреплены на противоположных стенках корпуса, просеивающее устройство выполнено из просеивающей сетки и, закреплённой под ней, резонирующей решётки и установлено с наклоном в сторону одного из генераторов колебаний, а кинематическая связь просеивающего устройства с генераторами колебаний, осуществляется путём механической передачи колебаний на резонирующую сетку.  The specified technical result is achieved by the fact that the resonance-wave classifier, comprising a housing, a sieving device installed with an inclination inside the housing and a pair of oscillation generators mounted on the walls of the housing and kinematically connected to the sieving device, is additionally equipped with frequency converters located outside the housing and electrically connected with oscillation generators, oscillation generators mounted on opposite walls of the housing, the screening device is made of a sifting grid and a resonant grating fixed under it and installed with an inclination towards one of the oscillation generators, and the kinematic connection of the sifting device with the oscillation generators is carried out by mechanical transmission of vibrations to the resonating grid.
За счёт обеспечения сложных волновых колебаний резонирующей решётки и сопряжённой с ней просеивающей сетки, при которых узлы и пучности постоянно перемещаются, исключается возможность образования застойных зон на просеивающей поверхности.  Due to the provision of complex wave oscillations of the resonating grating and the sieving grid associated with it, at which the nodes and antinodes are constantly moving, the possibility of the formation of stagnant zones on the sieving surface is excluded.
Устройство иллюстрируют чертежом.  The device is illustrated by a drawing.
На фиг.1 схематично изображен общий вид классификатора.  Figure 1 schematically shows a General view of the classifier.
Резонансно-волновой классификатор содержит корпус 1, просеивающее устройство 2, установленное с наклоном внутри корпуса, загрузочный люк 3, расположенный над просеивающим устройством, патрубок выпуска готового продукта 4 и патрубком выпуска отсева 5, расположенные под просеивающим устройством, генераторы колебаний 6 и 7, закрепленных на противоположных стенках корпуса, частотные преобразователями 8 и 9, каждый из которых расположен вне корпуса и электрически соединён с одним из генераторов колебаний с возможностью регулирования частоты питающего напряжения. Просеивающее устройство состоит из просеивающей сетки 10 и закреплённой под ней более массивной резонирующей решётки 11 и установлено с наклоном в направлении движения просеиваемого материала к патрубку выпуска отсева, а кинематическая связь просеивающего устройства с генераторами колебаний, осуществляется путём механической передачи колебаний на резонирующую решётку с помощью рычагов 12 и 13. The resonant-wave classifier comprises a housing 1, a screening device 2 mounted with an inclination inside the housing, a loading hatch 3, located above the screening device, the outlet pipe of the finished product 4 and the screening outlet pipe 5, located under the screening device, oscillation generators 6 and 7, mounted on opposite walls of the housing, frequency converters 8 and 9, each of which is located outside the housing and is electrically connected to one from oscillation generators with the ability to control the frequency of the supply voltage. The screening device consists of a screening grid 10 and a more massive resonant grating 11 fixed under it and is installed with an inclination in the direction of movement of the screened material to the screening outlet pipe, and the kinematic connection of the screening device with oscillation generators is carried out by mechanical transmission of vibrations to the resonating grid using levers 12 and 13.
Устройство работает следующим образом.  The device operates as follows.
В корпус 1 на просеивающее устройство 2 через загрузочный люк 3 подают сыпучий материал, подлежащий сортировке по фракциям. Материал падает на просеивающую сетку 10 и прижимает её к резонирующей решётке 11. Одновременно с помощью частотных преобразователей 8 и 9 на генераторы колебаний 6 и 7, соответственно, подают питающее электрическое напряжение. Генераторы колебаний с помощью рычагов 12 и 13 формируют волны поперечных колебаний в резонирующей решётке. Для устранения застойных зон на просеивающей поверхности сетки, которые могут образовываться в узлах стоячих волн, генераторы колебаний имеют разные частоты, не кратные друг другу. Частоты генераторов колебаний настраиваются в резонанс: один с нечётными тонами колебаний резонирующей решётки, а другой - с чётными. В данном случае 40 и 60 Гц. Конечный продукт, требуемой фракции выводится через патрубок 4, а отсев - через патрубок 5. Предлагаемый резонансно-волновой классификатор отличается высокой эффективностью, простотой конструкции, надежностью и экономичностью в работе, что обеспечивает значительный экономический эффект от его использования. In the housing 1 on the screening device 2 through the loading hatch 3 serves bulk material to be sorted into fractions. The material falls on the screening grid 10 and presses it against the resonating grid 11. At the same time, using frequency converters 8 and 9, the oscillation generators 6 and 7, respectively, are supplied with a supply voltage. Oscillators using levers 12 and 13 form waves of transverse vibrations in the resonant grating. To eliminate stagnant zones on the screening surface of the grid, which can form at the nodes of standing waves, oscillation generators have different frequencies that are not multiple to each other. The frequencies of the oscillation generators are tuned to resonance: one with odd tones of oscillations of the resonating grating, and the other with even ones. In this case, 40 and 60 Hz. The final product of the desired fraction is discharged through the pipe 4, and the screening through the pipe 5. The proposed resonant-wave classifier is characterized by high efficiency, simplicity of design, reliability and economy in operation, which provides a significant economic effect from its use.
