Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of sublimation furnace feeding equipment, especially relates to a single arsenic sublimation furnace feeding equipment. BACKGROUND

[0002] Single arsenic is a non-metallic element, which can play an important role in alloy manufacturing, pesticides and insecticides, drugs, glass manufacturing and semiconductor and laser technology. In the process of metal smelting, waste gas arsenic trioxide is often produced. In order to increase its utilization rate, single arsenic can be obtained by reducing arsenic trioxide. During reduction, arsenic trioxide needs to be sublimated. Therefore, a sublimation furnace is needed. When the prior art is used, the addition of raw materials in the sublimation furnace is mostly manually poured into the furnace. It is time-consuming and laborious, and the workers are exposed to the toxic raw materials for a long time. Even if they wear protective clothing, the long-term exposure can still affect their health. In addition, when the prior art is used, in order to increase the use efficiency of the sublimation equipment and reduce the cooling and heating time, the sublimation furnace with raw materials needs to be taken out for cooling after sublimation, so as to facilitate the subsequent removal of single arsenic obtained by sublimation and the replacement of another batch of sublimation furnace with raw materials for sublimation. In this process, the removed sublimation furnace and the sublimation furnace with raw materials added outside are exposed. When toxic raw materials are used, it can affect the safety of the environment and the workers, causing inconvenience. CONTENT OF THE UTILITY MODEL
