Изобретение относитс к микробиологической промьшшенности, в частности к аппаратам дл выращивани микроорганизмов , и может быть использовано также в химической промышленности .The invention relates to the microbiological industry, in particular to apparatus for growing microorganisms, and can also be used in the chemical industry.
Цепь изобретени - снижение энергозатрат на перемешивание и аэрацию путем использовани энергии аэрирующего газа дл вращени мешалки,The circuit of the invention is to reduce energy consumption for mixing and aeration by using the energy of the aerating gas to rotate the mixer,
На фиг, 1 представлено устройство общий вид с частичным вырывом, на фиг, 2 - разрез А-А на фиг. 1.FIG. 1 shows a general view of the device with a partial tear; FIG. 2 is a section A-A of FIG. one.
Устройство дл аэрации и переме- шив ани жидкости преимущественно к аппаратам дл выращивани микроорганизмов содержит установленную емкост 1 аппарата мешалку, содержащую вал 2, установленный в подшипниках скольжени 3, и прикрепленные к валу 2 лопасти , имеющи е в поперечном сечении Г-образную форму и выполненные закрытыми с торцов боковыми плоскост ми с образованием полостей д.п воздуха , заправочно-сливное устройство 5, перфорированный коллектор 6, укрепленный в емкости асимметрично относительно ее вертикальной оси, и дренажный патрубок 7,The device for aeration and mixing the liquid mainly to the microorganism growing apparatus contains an installed mixer tank 1 of the apparatus containing a shaft 2 mounted in slide bearings 3 and blades attached to the shaft 2, having a L-shaped cross-section and the lateral planes closed at the ends with the formation of cavities of an air gap, a refueling-discharge device 5, a perforated collector 6, fixed in the tank asymmetrically about its vertical axis, and a drainage pipe cuttings 7,
Устройство работает следующим образом .The device works as follows.
При подаче сжатого газа через коллектор 6 он проходит через перемешиваемую среду, аэриру ее, и скапливаетс в полост х, образованных Г-образными лопаст ми 4 и их боковыми плоскост ми. Дл обеспечени гарантированного поступлени газа под лопасти 4 перфорированный коллектор 6 размещен внутри емкости по образующей корпуса 1 и смещен влево относительно вертикальной оси корпуса . На газовые полости под лопаст миWhen the compressed gas is supplied through the collector 6, it passes through the mixed medium, aerating it, and accumulates in the cavities formed by the L-shaped blades 4 and their lateral planes. In order to ensure a guaranteed flow of gas under the blades 4, the perforated collector 6 is placed inside the container along the generatrix of housing 1 and shifted to the left relative to the vertical axis of the housing. On the gas cavity under the blades

4 действуют выталкивающие силы, привод щие мешалку во вращение. Таким образом, газ, подаваемый через коллектор 6, выполн ет две функции: аэрирует жидкость и осуществл ет ее перемешивание с помощью мешалки, Сброс отработанного газа из полости корпуса осуществл етс через дренажный патрубок 7, Заправка и слив жидкости осуществл етс через устройство 5,4, buoyancy forces act to drive the agitator into rotation. Thus, the gas supplied through the collector 6 performs two functions: aerates the liquid and mixes it with the help of an agitator. The exhaust gas is discharged from the body cavity through the drainage pipe 7, the filling and discharge of the liquid is carried out through the device 5,
Предлагаемое устройство обеспечивает перемешивание и аэрацию жидкости от одного источника энергии, которым вл етс газ. Следовательно, упрощаетс конструкци устройства (исключаетс привод мешалки) и снижаютс энергозатраты на перемешивание. Отсутствуют уплотнени между корпусом и вращающимс валом, В результате по вл етс возможность производить процесс аэрации и перемешивани при высоких давлени х.The proposed device provides mixing and aeration of a liquid from a single energy source, which is gas. Consequently, the design of the device is simplified (the drive of the agitator is eliminated) and the energy consumption for mixing is reduced. There are no seals between the casing and the rotating shaft. As a result, it is possible to perform the aeration process and mixing at high pressures.
