AI Technical Summary

Technical Problem

In existing technologies, when using a tracked trolley to transport radioactive materials, the track needs to pass through the shielding door, which affects the sealing and shielding performance of the shielding door.

Method used

An automated transfer system for shielded rooms is adopted, including a control device, a fixed roller conveyor, a sealed shielded door, and a moving roller conveyor. The control device controls the coordination between the sealed shielded door and the moving roller conveyor to achieve automated transfer of the transfer container and avoids the track running through the shielded door.

Benefits of technology

The automated transfer of radioactive materials was achieved, avoiding any impact on the sealing and shielding performance of the shielding door, and ensuring the safety and airtightness of the shielded room.

Abstract

This invention provides an automated transfer system and method for shielded rooms, enabling the transfer of radioactive materials while avoiding impact on the sealing and shielding performance of the shielding door. The automated transfer system includes a control device, a fixed roller conveyor, a sealed shielding door, and a movable roller conveyor. The fixed roller conveyor is located inside the shielded room and electrically connected to the control device, used to receive the transfer container and move it under the control of the control device. The sealed shielding door is located at an opening in the shielding wall of the shielded room and is electrically connected to the control device, used to open or close the shielded room under the control of the control device. The movable roller conveyor is located outside the shielded room and electrically connected to the control device, used to move outside the shielded room under the control of the control device, so that a portion of the upper part of the movable roller conveyor extends into the shielded room and docks with the fixed roller conveyor, and under the combined action of the fixed roller conveyor, moves the transfer container from the fixed roller conveyor to the movable roller conveyor.
