Description

Technical Field

[0001] This utility model belongs to the field of silica sol production technology, specifically a silica sol synthesis and feeding integrated device. Background Technology

[0002] Silica sol is a colloidal solution of silica with small particle size. It is usually a milky white or light blue transparent liquid. It has a large specific surface area, good adsorption, and also has good adhesion, dispersibility and fire resistance. It is widely used in many industries. In the production and synthesis of silica sol, the pH needs to be adjusted by adding a catalyst to achieve the preparation of silica sol.

This can lead to the catalyst concentration in the reaction system being too high or too low at any moment, affecting the purity and performance of silica sol. At the same time, uneven catalyst dispersion can cause local over-reaction, resulting in unstable silica sol quality. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides an integrated feeding device for the synthesis of silica sol, which solves the problems of difficulty in controlling the addition rate and uneven dispersion of catalyst in existing integrated feeding devices for the synthesis of silica sol.

[0029] When cylinder 15 is started, the output end of cylinder 15 drives the connecting shaft 16 to slide on the hopper 6.
