Изобретение относитс к аппаратам |дл массообменных процессов в жидких средах и может быть применено дл процессов экстракции, абсорбции,промывки , например, поваренной соли с целью обогащени ..The invention relates to apparatus for mass transfer processes in liquid media and can be applied to the processes of extraction, absorption, washing, for example, salt in order to enrich.

Известна лопастна вертикальна мешалка, включающа корпус, привод, вал, вращающийс с переменной углрвой скоростью, на котором с помощью т г закреплены к онтактные элементы в виде лопастей fllОднако в данной мешалке не достаточно интенсивна циркул ци жидкости в объеме аппарата, котора 66i сн етс отсутствием поступательных и вращательных пульсаций контактных элементов (лопастей).A known blade vertical stirrer, including a housing, an actuator, a shaft rotating at a variable angular velocity, on which are attached to contact elements in the form of fll blades. However, this mixer does not sufficiently circulate liquid in the volume of the apparatus, which is omitted translational and rotational pulsations of contact elements (blades).

Цель изобретени - интенсификаци процесса за счет увеличени степени массообмена.The purpose of the invention is to intensify the process by increasing the degree of mass transfer.

Указанна цель достигаетс тем, что вал снабжен шарнирным ромбом с направл ющими, на концах которыхThis goal is achieved by the fact that the shaft is provided with a hinged rhombus with guides, at the ends of which

установлены контактные элементы, выполненные в виде тарелок с лопаст ми , при этом вертикальна направл юща снабжена пружиной, а горизонтальна - винтами и грузами.contact elements are installed, made in the form of plates with blades, with the vertical guide provided with a spring and horizontal with screws and weights.

Лопасти тарелок, расположенных на горизонтальной направл ющей, перпендикул рны друг другу.The blades of the plates located on the horizontal rail are perpendicular to each other.

Claims

The apparatus consists of a housing 1, a drive 2, a shaft 3 that simultaneously serves as a hinged rhombus rotating with variable angular speed, a hinged rhombus i equipped with plates 5-8, springs 9 JJJ and 10, weights 11 and 12. Upper and lower plates Figures 5 and 6 form the translational pairs with the hinged rhombus k, and the middle plates 7 and | 8 o6pa3yct with the directional 17 of the hinge rhombus screw pairs. The blade of the plates located on the horizontal rail 17 is perpendicular to each other. The nuts of the plates 7 and 8 are covered with fingers 15 and TB, which are kept from being turned while the plates are rotated with hinged-diamond links. AfinapaT works as follows. A solid phase is fed from above into housing 1, and a liquid phase is fed from below, to the Torah, rising upward along the apparatus is distributed between the plates. When rotating shaft 3 with a variable angular velocity, for example, increasing its minimum value to the maximum, the centrifugal force, acting on weights 11 and 12 of the middle plates 7 and 8, pushes their prices to the periphery. At the same time, they unwind in their movement along the helical swivel guide 17 (diamond envelope) fitted with nuts, which leads to considerable fluid turbulization and intensification of the mass transfer process. During the rotation of the plates 7 and 8, the blades 13 and 1 change the angle of attack relative to the incident the flow of fluid during the rotation of the shaft 3, which leads to a change in the intensity of circulation of the fluid in the axial and radial directions, with the direction of circulation of the fluid changing along the axis of the apparatus twice during one turn of the plates, which also intensifies The movement of the plates 7 and 8 from the axis of the apparatus to the periphery is transmitted through links of the hinged diamond to the plates 5 and 6, which are moved in the axial direction towards each other, while the springs 9 and 10 are compressed. value to the minimum decreases the centrifugal force acting on the weights P and 12, the springs 9 and 10 push the plates 5 and 6 apart from each other in the axial direction. The movement of the plates 5 and 6 is transmitted through the links of the hinged rhombus to the plates 7 and 8, which, moving towards Chu each other along a helical guide 17, is unwound in the direction opposite to that which occurred when the plates moved from the center to the periphery. Thus, during rotation of the shaft 3 with a variable angular velocity, the pulsation of the plates takes place in two mutually perpendicular directions with their simultaneous rotation around the vertical guide 3 the pulsation of the plates around the horizontal guide 17, moreover, during the rotation of the plates 7 and 8, the angle blades 13 and 1 attacks, thus changing the intensity and direction of the circulation flow. All this leads to a significant intensification of the mass transfer process. Equipping the shaft 3 with a hinged rhombus 4 with guides contributes to the radial and axial pulsation of the contact elements, located 51X on. the ends of the guides. Such movement of the contact elements with their simultaneous rotation around the vertical guideline significantly intensifies the process of mass exchange. The weights located on the horizontal guide contribute to the approach of the plates 5 and 6 with increasing angular speed of the shaft 3, and the springs 9 and 10 contribute to the movement of the plates 5 and 6 from each other when the angular speed of the shaft 3 decreases. Equipping the horizontal guide with 17 screws installed the plates 7 and 8 on them promote the pulsation of the plates around the horizontal guide, which additionally intensifies the process of mass exchange. The arrangement of the blades of the plates of the horizontal guide perpendicular to each other bstvuet that during rotation of the plates 7 and 8 varies the angle of attack of the blades 13 and AND, thus varies the intensity and direction of the flow circulation. All this also intensifies the process of mass exchange. Claim 1. Pulsation mass-exchange apparatus, comprising a housing, a shaft with contact elements fixed on it, characterized in that, in order to intensify the process by increasing the mass transfer rate, the shaft is provided with a hinged rhomb with guides on the ends

the contact elements are installed in the form of plates with blades, wherein the vertical guide is provided with springs, and horizontal with screws and weights.

Lok, located on a horizontal HanpaajfiRiouieft, are perpendicular to each other.
