Mica powder unloading hopper with reverse sucking cover

Abstract

The invention belongs to the technical field of processing of mica powder, and relates to a mica powder unloading hopper with a reverse sucking cover. The mica powder unloading hopper comprises a cylindrical hopper; the top and the bottom of the hopper are respectively opened; an unloading plate movably connected with the inner wall of the hopper is arranged in the hopper, and is densely provided with unloading holes; the bottom of the hopper is connected with an inverted circular table cone type collecting barrel; an annular support plate is fixed in the collecting barrel; the support plate is provided with an elastic piece with elasticity and capable of deforming; the two ends of the elastic piece are fixedly connected with the unloading plate and the support plate; the collecting barrel is provided with a feed pipe below the support plate; and the feed pipe is communicated with the internal of the collecting barrel, and is provided with a valve. The unloading hopper further comprises the reverse sucking cover; the bottom of the reverse sucking cover is tightly connected with a reverse sucking pipe; the reverse sucking pipe is connected with the feed pipe; and the reverse sucking cover can be put in the hopper. The mica powder unloading hopper can form an automatic vibration effect, is uniform in unloading, and improves the classification effect.

Description

technical field [0001] The invention belongs to the technical field of mica powder processing, and relates to a mica powder feeding hopper with a suction cover. Background technique [0002] Mica powder is a non-metallic mineral containing various components, mainly SiO 2 , the content is generally around 49%, Al 2 o 3 The content is about 30%. Mica powder has good elasticity and toughness. Insulation, high temperature resistance, acid and alkali resistance, corrosion resistance, strong adhesion and other characteristics, it is an excellent additive. It is widely used in electrical appliances, welding electrodes, 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. [0003] The production process of mica powder needs to be graded, and the mica powder with different ...

AI Technical Summary

Problems solved by technology

[0003] The production process of mica powder needs to be graded, and the mica powder with different particle sizes is classified. This process requires the use of a classifier, and how to make the mica powder enter the classifier evenly is the main technical problem that affects the classification effect. In the prior art, the mica powder is usually directly sucked into the classifier through the vacuum suction of the classifier, but the feeding during the washing process is unstable, sometimes more and sometimes less, which seriously affects the classification effect
