Полость 4 сообщена посредством втулки 5 с полым валом 1 и отверстий 6 с межлопастным пространством 7, на периферии разделительного диска 2 выполнена кольцева щель 8, через . которую газ диспергирует в жидкость. Сверху и снизуThe mixer contains a hollow shaft 1, a separating disk 2 with flat radial blades 3 and an internal cavity 4. The cavity 4 is communicated through the sleeve 5 with the hollow shaft 1 and the holes 6 with the inter-blade space 7, on the periphery of the separating disk 2 there is an annular slot 8 through. which gas disperses into liquid. Up and down

К внутренним 11 торцам лопастей 3 закреплены отклон ющие пластины 12 в плане криволинейной формы с двум ветв ми 13 и 14, расположенные по обе стороны каждой лопасти 3 и образующие сужающиес каналы 15, при этом отклон ющие пластины 12 могут иметь в плане форму параболы с вершиной 16. обращенной к центру мешалки. Втулка 5 выполнена с отверсти ми 17 дл подвода газа в полость 4.blades 3 are mounted conical plates 9 and 10.

Турбинна мешалка работает следующим образом.Turbine agitator works as follows.
Приводитс во вращение погруженна в культуральную жидкость мещалка. Жидкость всасываетс в кольцевой зазор между валом 1 и коническими тарелками 9 и 10 и выбрасываетс наружу. В межлопастном пространстве, ограниченном коническими тарелками, организуетс движение жидкости в радиальном направлении . Скоростные потоки жидкости попадают в сужающиес в виде сопел каналы 15, образованные отклон ющими пластинами 12. На выходе из сопел, а также на периферии разделительного диска 2 имеет место эффект эжектиро- вани газа из внутренних полостей устройства . Газ всасываетс из наджидкост- ного пространства и поступает через полый вал 1, внутреннюю полость 4 разделительного диска 2, отверсти 6 и кольцевую щель 8 в жидкую среду.A bashalka immersed in the culture fluid is driven into rotation. The liquid is sucked into the annular gap between the shaft 1 and the conical plates 9 and 10 and is thrown out. In the inter-blade space bounded by conical plates, the movement of fluid in the radial direction is organized. Velocity flows of liquid enter the channels 15 narrowing in the form of nozzles formed by deflecting plates 12. At the exit from the nozzles, as well as on the periphery of the separation disk 2, the effect of gas ejection from the internal cavities of the device takes place. The gas is sucked from the supra-fluid space and flows through the hollow shaft 1, the internal cavity 4 of the separation disc 2, the holes 6 and the annular gap 8 into the liquid medium.
Параболическа форма отклон ющих пластин 12 обеспечивает хорощую обтекаемость их в радиальном направлении. Предел значений коэффициента пропорциональности уравнени ветвей параболы, при которых обеспечиваетс положительный эффект, равен 0,2-0,5. Дл уменьшени лобового сопротивлени и дл повышени эффективности эжекции газа с тыльной стороны лопасти крутизна ветвей 13 и 14 может быть различной, что выражаетс неравенством коэффициентов пропорциональности уравнени параболы, гдеThe parabolic shape of the deflecting plates 12 provides them with a good streamline in the radial direction. The limit of the proportionality coefficient of the equation of the branches of a parabola, at which a positive effect is achieved, is 0.2-0.5. To reduce the frontal resistance and to increase the efficiency of gas ejection from the back of the blade, the steepness of the branches 13 and 14 may be different, which is expressed by the inequality of the proportional coefficients of the parabola equation, where
а, дл ветви 14 параболы с атакующей стороны отклон ющей пластины 12 и а2 - дл ветви 13 с тыльной стороны отклон ющей пластины.a for the branch 14 of the parabola on the attacking side of the deflection plate 12 and a2 for the branch 13 on the back of the deflecting plate.
Использование изобретени за счет наличи в межлопастном пространстве сужающихс каналов обеспечивает дополнительный подсос воздуха в жидкость и тем самым увеличивает производительность мешалки по газу.The use of the invention due to the presence in the inter-blade space of narrowing channels provides additional air leaking into the liquid and thereby increases the gas productivity of the mixer.
