Abstract

Изобретение относитс к технике разделени суспензий в поле центробежных сил и может найти применение в химической, химико-фармацевтической, пищевой, микробиологической , угольной и смежных с ни mi отрасл х промышленности. Цель изобретени заключаетс в повышении надежности работы центрифуги путем исключени прорыва исходной суспензии через барабаны при ее неравномерном расходе и обеспечени посто нной толщины сло осадка. Планетарна центрифуга содержит корпус 1, установленный в нем ротоо 2, состо щий из вертикально расположенных вокруг центрального приходного вала 3 цилиндрических фильтрующих барабанов 4, установленных с возможностью вращени вокруг своей оси, снабженных спиральными лентами 5 дл перемещени осадка и имеющих в верхней части загрузочные участки 6, и устройство дл подвода исходной суспензии, состо щее из камеры 7 и прикрепленных к ней радиальных впускных патрубков 8, выходные участки которых расположены внутри фильтрующих барабаноз. Фильтрующие барабаны 4 на загрузочных участках 6 снабжены пластинчатыми лопаст ми 9, прикрепленными к их внутренней поверхности, а радиальные впускные патрубки 8 - соплами 10. 1 з. п. ф-лы, 3 ил. (Л СThis invention relates to a technique for separating suspensions in a field of centrifugal forces and may find application in the chemical, pharmaceutical and food, microbiological, coal and adjacent industries of the industry. The purpose of the invention is to increase the reliability of the centrifuge by eliminating the breakthrough of the initial suspension through the drums at its uneven consumption and ensuring a constant thickness of the sediment layer. The planetary centrifuge includes a housing 1, a rotoo 2 mounted therein, consisting of cylindrical filter drums 4 vertically arranged around a central receiving shaft 3 mounted rotatably around its axis, provided with spiral bands 5 for moving the sediment and having loading sections 6 and a device for supplying the initial suspension, consisting of the chamber 7 and the radial inlet pipes 8 attached to it, the output sections of which are located inside the filter drums .

Claims

Claim

1. A planetary centrifuge containing a housing, a rotor installed in it, consisting of cylindrical filter drums vertically arranged around a central drive shaft and mounted rotatably around its axis, provided with spiral tapes on the inner surface to move the sediment and having loading sections in the upper part, and a device for supplying an initial suspension, consisting of a chamber and radial inlet pipes attached to it, the outlet sections of which are located inside the filter drums, characterized in that, in order to increase the reliability of the centrifuge by eliminating the breakthrough of the initial suspension through the drums at an uneven flow rate and ensuring a constant thickness of the sediment layer, the filter drums at the loading sections are equipped with plate blades attached to their inner surface, and radial inlet nozzles - nozzles, fortified so that they are directed to these blades.

2. A centrifuge according to π, 1, characterized in that the loading section of each filter drum is cone-shaped, and lamellar blades are attached to its surface along a generatrix.
