Abstract
1. Вакуумный аппарат для разложения отходов арсенида галлия, состоящий из цилиндрической вакуумной камеры с цилиндрическим многослойным экраном, внутри которой по оси размещен цилиндрический нагреватель с нижним токовводом, в полости которого на подине вдоль оси установлена колонна испарительных тарелей, накрытых крышками и конденсатором, а подина снабжена каналом перетока с герметичным сборником галлия, отличающийся тем, что на крышку конденсатора герметично установлен загрузочный бункер сырья с затвором и вентилями вакуумирования и напуска азота, а испарительные тарели выполнены в виде конуса с диаметром малого основания, увеличивающимся от нижней к верхней тарели, и с отверстиями у большего основания для стока галлия на подину, соединенную со сборником через сифонный затвор.2. Вакуумный аппарат по п. 1, отличающийся тем, что наклон стенки конуса тарели к горизонтали составляет 20-35°.3. Вакуумный аппарат по п. 1, отличающийся тем, что тарели у большего основания выполнены с отверстиями перетока и установлены снизу вверх попеременно с противоположных сторон.4. Вакуумный аппарат по п. 1, отличающийся тем, что диаметры малых оснований тарелей увеличиваются для каждой вышестоящей тарели с образованием расширяющегося паропровода.5. Вакуумный аппарат по п. 1, отличающийся тем, что диаметр малого основания верхней тарели меньше, чем диаметр основания загрузочного бункера для обеспечения распределения шихты по тарелям при загрузке.6. Вакуумный аппарат по п. 1, отличающийся тем, что загрузочный бункер по оси у нижнего основания снабжен конусом.7. Вакуумный аппарат по пп. 1 и 6, отличающийся тем, что основание загрузочного бункера снабжено затвором с1. A vacuum apparatus for the decomposition of gallium arsenide waste, consisting of a cylindrical vacuum chamber with a cylindrical multilayer screen, inside of which there is a cylindrical heater with a lower current lead, in the cavity of which a column of evaporation plates covered with lids and a condenser is installed along the axis along the axis, and the bottom equipped with an overflow channel with a sealed gallium collector, characterized in that a feed hopper of raw materials with a shutter and vacuum valves is hermetically mounted on the condenser cover and nitrogen inlet, and the evaporation plates are made in the form of a cone with a diameter of a small base increasing from the lower to the upper plate, and with holes at the larger base to drain gallium onto the bottom connected to the collector via a siphon shutter. 2. The vacuum apparatus according to claim 1, characterized in that the inclination of the wall of the plate cone to the horizontal is 20-35 °. 3. A vacuum apparatus according to claim 1, characterized in that the plates at the larger base are made with overflow holes and are installed alternately from opposite sides from the bottom up. The vacuum apparatus according to claim 1, characterized in that the diameters of the small bases of the plates increase for each higher plate with the formation of an expanding steam pipe. The vacuum apparatus according to claim 1, characterized in that the diameter of the small base of the upper plate is less than the diameter of the base of the loading hopper to ensure the distribution of the charge on the plates during loading. A vacuum apparatus according to claim 1, characterized in that the feed hopper is axially provided at the lower base with a cone. Vacuum apparatus 1 and 6, characterized in that the base of the loading hopper is equipped with a shutter with
