一种放射性物质运输容器用防火装置
摘要：
本实用新型属于防火结构技术领域，具体涉及一种放射性物质运输容器用防火装置。它包括与容器上端连接的防火盖，以及套在容器外壳的防火套，所述的防火盖上设有通气孔。防火盖由内壳、外壳和环板焊接组成，形成的腔体内填充耐火材料。防火套是由顶板、底板、内筒、外筒焊接组成，形成的腔体内填充耐火材料。防火盖上设有通气孔，便于容器上部的热量及时排出，在防火的同时防止了容器顶部热量的积聚。防火装置采用组合式结构，通过螺栓与容器连接，组装使用方便。防火盖和防火套采用组焊形式制作，加工容易。
摘要（英）：

The utility model particularly relates to a fireproof device for a radioactive substance transportation container, which belongs to the technical field of a fireproof structure and comprises a fireproof cover connected with the upper end of the container and a fireproof sleeve sheathed on a container shell. Vent holes are arranged on the fireproof cover; the fireproof cover is formed through welding of an inner shell, an outer shell and a ring plate; and fireproof materials are filled in a formed cavity body. The fireproof sleeve is formed through welding of a top plate, a bottom plate, an inner cylinder and an outer cylinder; and the fireproof materials are also filled in the formed cavity body. The vent holes arranged on the fireproof cover are convenient for timely discharging heat at the upper part of the container, thereby preventing heat accumulation at the top part of the container at the same time as realizing the fireproof effect. The fireproof device adopts a combined structure and is connected with the container by a bolt. The assembling and using are convenient. The fireproof cover and the fireproof sleeve are manufactured through installed welding, the processing is easy.
