Description

Technical Field

[0001] The invention relates to the technical field of storage devices, and in particular to a titanium dioxide storage device with good sealing performance. Background Art

[0002] Titanium dioxide is a white polycrystalline compound whose main component is titanium dioxide (TiO2). It is considered to be the best white pigment in the world and is widely used in industries such as coatings, plastics, papermaking, printing inks, chemical fibers, rubber, and cosmetics. However, due to its small particle size and strong hygroscopicity, titanium dioxide easily absorbs moisture from the air and becomes damp during storage. After absorbing moisture, on the one hand, it affects the precise quantification of materials in subsequent production, and on the other hand, the titanium dioxide easily clumps after absorbing moisture. Therefore, during transportation, it needs to be placed in a sealed container for storage to reduce the moisture absorption rate of titanium dioxide.

[0003] For example, application number: CN202120765779.1 involves a storage device for titanium dioxide with good airtightness, which relates to the technical field of auxiliary devices for titanium dioxide storage. In order to solve the problem that the existing storage device for titanium dioxide often leaks and wastes titanium dioxide due to poor sealing during storage, a cover to upper block is arranged above the fixed bottom block, and two cover to upper blocks are arranged, and a sealing cover plate is arranged above the cover to upper block, and a fixed lower block is arranged at the lower end of the fixed bottom block and the lower end of the cover to upper block, and a sealing lower block is arranged below the fixed lower block, and the sealing lower block is connected to the fixed lower block by viscosity, and a limiting lower plate is arranged on the outside of the fixed lower block, and a sealing inner block is arranged on the inner wall of the limiting lower plate, and the sealing inner block is connected to the limiting lower plate by viscosity.

[0004] However, there are some shortcomings in the design of the current titanium dioxide storage device. First, after the titanium dioxide is stored in the container, there may be a certain gap between the titanium dioxide and the inside of the container, which leads to the retention of air and easily causes the titanium dioxide to become damp. Secondly, the titanium dioxide lacks a crushing and agglomerating structure. If the titanium dioxide agglomerates, if not handled in time, the agglomerates will become larger and larger, thus affecting the quality of the entire batch of titanium dioxide. Summary of the invention

[0005] In response to the above problems, one purpose of the present application is to remedy these shortcomings, and more specifically to provide a titanium dioxide storage device with good sealing properties, which can avoid the existence of gaps between the titanium dioxide and the interior of the container, thereby preventing the residue and entry of air, and can crush the lumps of titanium dioxide to prevent the lumps from continuing to grow.
