Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mica powder production, in particular to a mica powder feeding hopper structure. Background Art
[0002] Mica powder is a non-metallic mineral containing a variety of components, mainly SiO2, which is generally about 49%, and Al2O3, which is about 30%. Mica powder has good elasticity and toughness. It is an excellent additive with the characteristics of insulation, high temperature resistance, acid and alkali resistance, corrosion resistance, and strong adhesion. It is widely used in electrical appliances, welding rods, rubber, plastics, papermaking, paints, coatings, pigments, ceramics, cosmetics, new building materials and other industries, and has a wide range of uses. With the continuous development of science and technology, people have opened up new application fields. In the production process of mica powder, it is necessary to feed the mica powder evenly to ensure the structural stability of the mica powder products. The mica powder is fed through a spiral conveyor roller to ensure uniform transportation. When feeding, a scraper is needed to scrape the inner wall of the hopper to avoid the sticking of the mica powder. However, due to the flipping of the scraper, the mica powder at the bottom of the hopper will be flipped up, and the conveyor roller cannot quantitatively transport the mica powder, resulting in uneven feeding. For this reason, we propose a mica powder feeding hopper structure. Utility Model Content
