Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of silica sol processing, in particular to a silica sol impurity removal device. Background Technique
[0002] Silica sol is a dispersion of nanoscale silicon dioxide particles in water or a solvent. Since the SiO2 in silica sol contains a large amount of water and hydroxyl groups, silica sol can also be expressed as mSiO2.nH2O. There are different ways to prepare silica sol, and the most common methods include the ion exchange method, the one-step hydrolysis method of silicon powder, the hydrolysis method of silane, etc. At present, the main production methods of silica sol are the ion exchange method and the silicon powder hydrolysis method. In the production process of the silicon powder hydrolysis method, silicon powder cannot be completely removed by the filtration process, and some unreacted fine silicon powder will pass through the filter cloth and enter the product, forming solid impurities in the silica sol. After standing for a period of time, a small amount of black precipitate will form, affecting the quality of the product.
[0003] At present, the Chinese patent with the publication number of CN219023465U discloses an impurity removal device for silica sol processing, including a machine body. The upper side of the right end of the machine body is fixedly connected with a feed inlet. The middle part of the top of the machine body is threadedly connected with a pressure rod. The bottom end of the pressure rod is fixedly connected with a pressing plate. Both sides of the top of the machine body are fixedly connected with driving motors. The output ends of the driving motors penetrate through the inner wall of the top of the machine body and are fixedly connected with threaded rods. The middle parts of the rod bodies of the threaded rods are rotatably connected with positioning blocks. One end of the outer side of the positioning blocks is fixedly connected to the inner wall of the machine body. The bottoms of the threaded rods are threadedly connected with fixing blocks. One end of the outer side of the fixing blocks is fixedly connected with electric push rods. The telescopic ends of the electric push rods are fixedly connected with connecting plates. Both ends of the inner side of the connecting plates are rotatably connected with rollers. However, when removing impurities and filtering silica sol in the above patent, it is difficult to continuously filter silica sol, reducing the impurity removal efficiency during silica sol processing. For this reason, we propose a silica sol impurity removal device to solve the above problems. Content of the Utility Model
