Description

  The present invention relates to a powder handling apparatus and a powder handling method used when conveying a powder that may contain a radioactive substance in a transfer facility.

  Conventionally, for example, the method of carrying in / out the adsorption tower described in Patent Document 1 is intended to easily take in and out the adsorbing tower in an airtight manner from the glove box. This adsorption tower loading / unloading method is such that one opening of a cylindrical plastic bag is sealed in a bag holding portion provided so as to surround a suspension piece provided on the upper surface of the adsorption tower, and the other The opening is fixed to the bag holding part of the glove box in a sealed state. The adsorption tower is taken out from the inside of the glove box, the plastic bag is squeezed under the adsorption tower and hermetically sealed at two places, and the seal part is cut at the middle part.

  In addition, conventionally, for example, the transport sample analysis system and analysis method described in Patent Document 2 can perform sample analysis as it is without opening the sample container, and can perform sample analysis in a shorter time than conventional methods. The purpose is to reduce the possibility of contamination of workers and reduce the amount of waste. In this transport sample analysis system and analysis method, a sample to be analyzed is collected in a sample container in a sampling device section in a sampling chamber, and is conveyed by an air flow through an air pipe. In the analyzer unit in the analysis chamber, the extraction cell of the sample container is irradiated with light, and the transmitted light and fluorescence are measured to perform an analysis applying a photoreaction without opening the sample container.

  The airtight wall 2 is provided inside the sealed casing 1. The airtight wall 2 divides the internal space of the hermetic casing 1 into two parts, a first region 1A and a second region 1B, while maintaining airtightness. That is, the internal space of the sealed casing 1 is divided into two parts, the first region 1A and the second region 1B, by the airtight wall 2, and the first region 1A and the second region 1B are separated from each other. .

  The through hole 3 is provided through the hermetic wall 2. That is, the through hole 3 communicates the first region 1A and the second region 1B divided by the airtight wall 2.

  As shown in FIGS. 1 and 2, the door body 4 is supported so as to be swingable about a shaft 4 a provided with respect to the airtight wall 2. The door body 4 opens the through hole 3 provided in the hermetic wall 2 by swinging away from the hermetic wall 2. On the other hand, the door body 4 closes the through hole 3 while maintaining airtightness by swinging closer to the airtight wall 2. Further, the swing when the door body 4 is opened moves toward the first region 1A, prevents the movement toward the second region 1B side, and maintains the airtightness of the door body 4 so that the airtight wall 2 is maintained. It is comprised in the form which contacts the wall surface by the side of 1st area | region 1A through a sealing material (not shown). The opening / closing operation of the door body 4 is performed from the first region 1A. Further, the door body 4 is maintained in a state where the through hole 3 is closed by a lock mechanism (not shown). The door body 4 is not limited to a configuration that swings with respect to the hermetic wall 2, and may be configured to be detachable from the hermetic wall 2.

  As shown in FIGS. 1 and 2, the storage container 5 includes a storage container body 5 </ b> A and a lid 5 </ b> B.
