Claims (1)

Пневматическое дозирующее устройство для дозирования порошкообразных материалов, например при подаче окиси алюминия и фторида алюминия в электролизную ячейку для получения алюминия, состоящее из контейнера в форме относительно длинного закрытого канала или подобной конструкции с псевдоожижающим элементом, установленным в основании для подачи воздуха с целью псевдоожижения находящегося в канале материала. Контейнер снабжен впуском для подачи материала из хранилища в виде бункера или подобной конструкции и выпуском для дозированной выгрузки материала из него. Область под впуском неактивна и не снабжается псевдоожижающим воздухом, в то время как воздух с помощью электронно управляемого магнитного клапана прерывисто подается в псевдоожижающий элемент.A pneumatic metering device for dispensing powdered materials, for example, when aluminum oxide and aluminum fluoride are fed into an aluminum electrolysis cell, consisting of a container in the form of a relatively long closed channel or similar structure with a fluidizing element mounted in the base for supplying air to fluidize channel material. The container is equipped with an inlet for supplying material from the storage in the form of a hopper or similar structure and an outlet for the metered discharge of material from it. The area under the inlet is inactive and is not supplied with fluidizing air, while the air is intermittently supplied by an electronically controlled magnetic valve to the fluidizing element.
