Description

Technical Field

[0001] The utility model relates to a silicon dioxide powder packaging mechanism, belonging to the field of silicon dioxide production. Background Art

[0002] Silica is an acidic oxide, and its corresponding hydrate is silicic acid. Silica is one of the most important compounds of silicon. After the processing of silica powder is completed, it needs to be packaged to facilitate its storage or transportation. Silica powder is usually packed into woven bags for storage. The woven bags are placed on the lower side of the feed pipe of the screw conveyor installed at the bottom of the silica powder storage bin, and the feed pipe is extended into the woven bag. When the screw conveyor is working, the silica powder in the silica powder storage bin falls into the woven bag through the feed pipe. Because the diameter of the feed pipe is much smaller than the diameter of the woven bag mouth, the silica powder is easy to diffuse out through the gap between the feed pipe and the woven bag mouth during the packaging process. Therefore, it is necessary to design a silica powder packaging mechanism that prevents the silica powder from diffusing randomly during the packaging process. Utility Model Content

[0010] Beneficial effects of the utility model:

[0011] 1.
