Automatic proportioning and dissolving kettle for aluminum hydroxide powder production

Abstract

The invention relates to the technical field of aluminum hydroxide powder production, in particular to an automatic proportioning and dissolving kettle for aluminum hydroxide powder production, which comprises a dissolving kettle shell, a proportioning shell is mounted on one side of the outer wall of the top of the dissolving kettle shell, a protective shell is mounted on the top of the outer wall of one side of the proportioning shell, and a connecting shell is mounted on the outer wall of the top of the dissolving kettle shell. The inner wall of the top and the inner wall of the bottom of the dissolving kettle shell are rotationally connected with the same hollow rotating pipe, and the top of the hollow rotating pipe extends into the protective shell. Raw materials are prevented from caking and depositing to the bottom after being added into the dissolving kettle shell, the dissolving sufficiency is improved, the mixing rod can be driven to rotate through rotation of the hollow rotating pipe, the raw material mixing efficiency is improved, the filter cartridge is installed on the outer wall of the arc-shaped block, and the working stability of the filter cartridge can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of aluminum hydroxide powder production, in particular to an automatic proportioning dissolving kettle for aluminum hydroxide powder production. Background technique [0002] Active ultra-fine aluminum hydroxide is currently the most advanced high-voltage flame-retardant insulation filling material in the world. It is mainly suitable for high-voltage, ultra-high-voltage composite insulators, high-voltage wires and cables, composite insulators, etc. Improve the compatibility between inorganic flame retardants and organisms, it has good cleaning power, high reinforcing performance, and hydrophobicity HC1 grade. Usually in the process of producing active ultrafine aluminum hydroxide, the raw material of aluminum hydroxide and sodium hydroxide lye are first mixed. According to a certain proportion, it is added into the dissolving cylinder for mixing, and reacts with each other to dissolve to generate a sodium al...

Problems solved by technology

[0004] However, the above-mentioned patent has the following deficiencies. Firstly, aluminum hydroxide raw material and sodium hydroxide lye are added into the dissolving chamber according to a certain ratio for mixing, which makes the raw materials agglomerated and deposited easily. Although a crushing mechanism is provided, the agglomerated cannot be removed The raw materials are sufficiently crushed, thereby reducing the quality of the dissolution, and now the weight of the aluminum hydroxide raw materials is manually weighed, and then added to the dissolution kettle. The entire dissolution process still needs to be manually operated, which is inconvenient to use and cannot be automated. Proportioning dissolution, so there is an urgent need for an automatic proportioning dissolution kettle for the production of aluminum hydroxide powder to solve the above problems
