Description

Technical Field

[0001] The invention relates to the technical field of storage and feeding, in particular to a silica sand storage and feeding device. Background Art

[0002] In the glass production lines of factories in the building materials, light industry and other industries, as people's requirements for the quality of glass products become higher and higher, the requirements for the moisture content and chemical uniformity of glass mineral raw materials (especially silica sand) are correspondingly higher and higher. High-quality raw materials (especially silica sand) are an important guarantee for the production of high-quality float glass, and the stability of raw materials has a decisive influence on the quality of glass. Traditionally, silica sand is generally stored in silica sand homogenization warehouses or hanging warehouses. The chemical composition and moisture content of silica sand fluctuate from time to time, especially the moisture content is affected by external conditions such as production and transportation, and it is more likely to fluctuate when entering the factory. In order to reduce the adverse effects of fluctuations in the moisture and chemical composition of silica sand on production and batch quality, high-end glass production lines generally store silica sand in homogenization warehouses. Taking homogenization measures during the storage of silica sand is conducive to improving the quality of batches.

[0003] In order to save costs, glass production lines that do not require high glass quality generally use silica sand crane storage to store silica sand. Compared with the homogenization warehouse, the silica sand crane storage has the advantages of large storage capacity per unit area, small footprint, and small equipment investment, but it does not have the effect of homogenization warehouse on the moisture and chemical composition of silica sand and high degree of automation. With the increasing tonnage of glass production lines, or some projects are limited by the floor area, if a silica sand homogenization warehouse is designed, it is difficult to meet the requirements of silica sand reserves; if a silica sand crane storage is designed, the uniformity of the moisture and chemical composition of silica sand is much worse than that of the homogenization warehouse, and the degree of automation is low, it is difficult to meet the requirements of high-end production lines for the quality of silica sand raw materials. In view of the shortcomings of the existing silica sand storage and feeding system, the purpose of the present invention is to provide a silica sand storage and feeding device with greater storage capacity per unit area, better homogenization effect, and higher degree of automation, so that the new silica sand storage and feeding device can take into account the advantages of both silica sand homogenization warehouse and crane storage warehouse, and meet the requirements of high-end production lines for silica sand storage and feeding devices. Summary of the invention
