Изобретение относитс к устройствам дл перемешивани и диспергировз ни и может быть использовано в химической , нефтехимической, пишевой и других отрасл х промышленности.The invention relates to devices for mixing and dispersing and can be used in the chemical, petrochemical, writing and other industries.
Целью изобретени вл етс повышение эффективности смешени путем увеличени степени гомогенизации и диспергировани смешиваемых компо- нентов.The aim of the invention is to increase the mixing efficiency by increasing the degree of homogenization and dispersion of the components to be mixed.
На чертеже изображен кавитацион- ный смеситель, общий вид.The drawing shows a cavitation mixer, general view.
Смеситель содержит .корпус 1 с патрубками 2 и 3 подачи смешиваемых ком понентов, устройство дл перемешивани , выполненное в виде вала 4 с закрепленными на нем лопаст ми 5, имеющими суперкавитируклций профиль, на концах которых жестко закреплен цилиндр 6. В стенках цилиндра 6 и корпуса 1 выполнены отверсти 7 и 8. Отверсти 7 в стенке цилиндра 6 расположены напротив отверстий 8 в стенке корпуса 1 за лопаст ми 5 по нап- равлению потока.The mixer contains a housing 1 with nozzles 2 and 3 supplying the components to be mixed, a mixing device made in the form of a shaft 4 with blades 5 attached to it, having a supercavity profile, at the ends of which the cylinder 6 is rigidly fixed. In the walls of the cylinder 6 and the housing The holes 1 are 7 and 8. The holes 7 in the wall of the cylinder 6 are located opposite the holes 8 in the wall of the housing 1 behind the blades 5 in the direction of flow.
Кавитационный смеситель работает следукхцим образом.The cavitation mixer works in the following way.
Основной компонент подают в патрубок 2. При вращении вала 4 за ло- паст ми 5 образуетс каверна, Подме- шиваемьп компонент подают через патрубок 3 в коллектор 9, из которого о в момент совпадени отверстий 7 в стенке цилиндра 6 с отверсти ми 8 в стенке корпуса 1 поступает в зону схлопывани кавитационных пузырьков. При этом давление в зоне схлопывани увеличиваетс . В момент перекрыти отверстий 8 стенками цилиндра 6 рас- ход подмешиваемого компонента в зону схлопывани кавитационных пузырьков уменьшаетс и прекращаетс совсем, что приводит к падению давлени вThe main component is fed to the nozzle 2. When the shaft 4 rotates, a cavity is formed behind the nozzles 5, the mixing component is fed through the nozzle 3 to the collector 9, from which the holes 7 in the wall of the cylinder 6 coincide with the holes 8 in the wall housing 1 enters the collapse zone of cavitation bubbles. The pressure in the collapse zone increases. At the moment when the holes 8 are blocked by the walls of the cylinder 6, the flow rate of the component being mixed into the collapse zone of the cavitation bubbles decreases and stops completely, which leads to a drop in pressure

ней. В результате в зоне схлопывани пузырьков создаютс колебани давлени , частота которых зависит от частоты вращени вала 4 и количества отверстий 7 и 8 в стенках цилиндра 6 и корпуса 1. Эти колебани давлени вызывают одновременное схлопывание большого количества кавитационных пузырьков , что приводит к увеличению интенсивности смешени компонентов, создание колебаний давлени в зоне схлопывани кавитационных пузырьков при вращении вала за счет периодического совпадени отверстий в цилиндре и корпусе, через которые подаетс подмешиваемый компонент, обеспечивает их частоту более 1000 Гц.her. As a result, pressure oscillations are created in the bubble collapse zone, the frequency of which depends on the frequency of rotation of shaft 4 and the number of holes 7 and 8 in the walls of cylinder 6 and housing 1. These pressure variations cause a simultaneous collapse of a large number of cavitation bubbles, which leads to an increase in the mixing ratio of the components , creating pressure oscillations in the collapse zone of cavitation bubbles during rotation of the shaft due to periodic coincidence of the holes in the cylinder and the housing, through which the mixing is applied component, provides their frequency more than 1000 Hz.
Предлагаемый кавитационный смеситель повышает степень гомогенизации и диспергировани в результате непосредственной подачи подмешиваемого компонента в зону схлопывани кавитационных пузырьков.The proposed cavitation mixer increases the degree of homogenization and dispersion as a result of the direct supply of the admixed component to the collapse zone of cavitation bubbles.
