Description

Technical Field

[0001] The present invention relates to the technical field of sodium silicate production, and particularly to a quartz sand weighing and feeding device and a nano sodium silicate production system. Background Art

[0002] Sodium silicate production systems play an important role in modern chemical processes. The chemical reactions involved usually include high-temperature reactions of various raw materials such as soda ash, silica sand, and lime. Sodium silicate, also known as water glass, is an important chemical raw material widely used in construction, foundry, environmental protection, and many other industries. Under high-temperature conditions, the reaction between soda ash and silica sand produces sodium silicate, and this process requires a high-temperature furnace or reactor to provide sufficient heat to ensure the smooth progress of the reaction.

[0003] During the production process, the formation of sodium silicate not only requires precise proportioning but also strict control over the transportation, weighing, and mixing of raw materials. Currently, especially when producing silicon-based new materials such as white carbon black, the proportional mixing of quartz sand and soda ash is a crucial step. To achieve this goal, quartz sand and soda ash are usually transported to the raw material bins separately and weighed. This operation process is relatively cumbersome. The traditional operation method requires workers to manually receive the materials using a small cart and then push the cart to the designated area for weighing. After weighing, the workers also need to manually pour the quartz sand in the cart into the mixing bin. This not only increases the labor cost but also improves the complexity of the operation and potential safety risks. Summary of the Invention
