detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Below in conjunction with accompanying drawing and embodiment the utility model is described in detail.

As shown in Figure 1, it shows a moisture-proof storage device for ultrafine powder materials. The device includes a glass container 1 , a glass container cover 2 , a silica gel desiccant 3 and a small vacuum pump 4 . The glass container 1 is a thickened cylindrical transparent tempered glass container for containing ultrafine powder material 5 . The glass container 1 is divided into an upper part 6 and a lower part 7 of the container, and the upper part 6 and the lower part 7 of the container are separated by a circular ceramic partition 8; The hole 9 is used for the communication between the upper part 6 of the container and the lower part 7 of the container; the space formed by the upper surface of the ceramic partition 8 and the upper part 6 of the container is dedicated to holding the ultrafine powder material 5; the ceramic partition The space formed by the lower surface of the plate 8 and the lower part 7 of the container is dedicated to hold the silica gel desiccant 3; the silica gel desiccant 3 is a color-changing silica gel, which is used for drying the ultrafine powder material 5 in the container; the silica gel desiccant The agent 3 is packed in a small cylindrical glass container 10 without a cover (to facilitate the taking and placing of the silica gel desiccant), and is placed in the lower part 7 of the container. The glass container 1 is provided with a glass container cover 2. The glass container cover 2 is a thickened transparent tempered glass container. Vaseline 11 is coated between the glass container 1 and the glass container cover 2 to ensure the airtightness of the device. There is a thickened tempered glass pipe 12 on the upper part 6 of the glass container 1 , and a valve 13 is provided on the glass pipe 12 for controlling the connection and disconnection between the glass container 1 and the small vacuum pump 4 .
