Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of silica sol purification, in particular to a kind of purification device for silica sol. BACKGROUND

[0002] Silica sol is a colloidal solution in which nanoscale silica (SiO2) particles are uniformly dispersed in water or other liquid media. It is widely used in fields such as coatings, ceramics, electronics, pharmaceuticals, and catalysts. Due to its excellent adhesion, heat resistance, and chemical stability, silica sol has important application value in industrial production and scientific research. However, impurities or uneven particles may be introduced during the preparation process, which not only affects the performance of silica sol but also may cause quality problems in subsequent applications. Therefore, it is crucial to purify silica sol to remove impurities, improve its purity and uniformity, and ensure its excellent performance in various application scenarios.

[0003] In the prior art, existing silica sol purification filtration equipment mostly adopts an integrated structure and mainly uses gravity filtration or centrifugal method for automatic filtration purification. The gravity filtration method utilizes the gravity of silica sol itself to pass through the filter membrane to achieve filtration purification. The centrifugal method separates larger particles and impurities by centrifugal force generated by high-speed rotation.

[0004] However, when the existing silica sol purification filtration equipment uses gravity filtration method, the purification speed is slow, resulting in low processing efficiency. Especially when handling a large amount of silica sol, the long filtration time significantly increases production cost and cycle. On the other hand, when using centrifugal method for purification, silica sol is easily attached to the inner wall of the filter box, thereby blocking the filter holes and affecting the filtration effect of the filter membrane. In addition, this blocking phenomenon needs to be cleaned intermittently by manual operation, which increases the maintenance workload and operation complexity, further reducing the practicality and reliability of the entire device.
