Description

Technical Field

[0001] The invention relates to the technical field of material storage, and in particular to a fumed silica powder silo. Background Art

[0002] Fumed silica is fumed silica, chemically known as hydrated silicon dioxide, with a chemical formula of SiO 2 ·nH 2 O is an extremely fine nano-scale amorphous silicon dioxide obtained by high-temperature hydrolysis of halosilanes in a hydrogen-oxygen flame. It has a small particle size, uniform particle size distribution, and a large specific surface area, so it has a high surface activity. Fumed silica is widely used in polymer composite materials, silicone rubber, coatings, electronic packaging materials, colloidal batteries, ceramics, plastics, fiberglass, sealants, papermaking, food, cosmetics, gel coat resins, chemical mechanical polishing and other industries, and can play a role in reinforcement, thickening, thixotropy, and matting.

[0003] After the production of fumed silica is completed, it needs to be stored in the silo and then evenly transported to the vacuum packaging machine; during the transportation process, it is necessary to ensure that the material is discharged evenly, otherwise it is easy to cause problems such as empty vacuum packaging bags and insufficient loading. Due to the small particle size and light density of fumed silica powder (bulk density 200-400kg / m³), it is very easy to form arches and bridges during the discharging process, resulting in uneven discharging or even failure to discharge. In addition, because there will be acidic substances remaining in the production process of silica, the storage tanks are mostly made of fiberglass, and it is impossible to use vibration and other methods to break the arch; the existing arch breaking method is the air-blowing arch breaking method. Although the air-blast arch-breaking method can effectively break the arches and discharge the material, it also has the following problems: 1) When using the air-blast arch-breaking method, the fumed silica powder is likely to become loose, causing the bulk density to drop again, reducing the effective capacity of the silo, and is not good for the later vacuum packaging; 2) During the production process of fumed silica, some acidic substances will remain. When the gas is discharged by the air-blast arch-breaking method, the fumed silica powder and some acidic substances will be mixed in, which need to be treated before being discharged, increasing the tail gas treatment pressure. In addition, due to the interaction between particles, the influence of temperature and humidity, fumed silica is prone to agglomeration, which will also lead to uneven discharge or even failure to discharge.
