Automatic feeding reaction system and application thereof and feeding method of solid raw material

Abstract

The invention relates to the field of chemical industry, in particular to an automatic feeding reaction system and an application thereof and a feeding method of a solid raw material. The system comprises a feeding apparatus (1), a liquid sealing apparatus (2) and a reaction apparatus (3) which are connected in sequence; wherein a conveying apparatus (4) is arranged inside the liquid sealing apparatus, and a material passing through a liquid sealing solvent in the liquid sealing apparatus is delivered to the reaction apparatus by the conveying apparatus. The application of the automatic feeding reaction system in a closed reaction using a solid raw material as a starting raw material is also provided. The feeding method of the solid raw material in a closed environment is further provided,and the feeding method comprises: continuously adding the solid raw material and making the solid raw material pass through the liquid sealing solvent to remove a gas carried in the solid raw material, and adding the carried-gas removed solid raw material into a closed reactor to carry out a reaction. According to the system and method, the continuous and automatic feeding of the reaction solid raw material is realized, the labor intensity is greatly reduced, the production efficiency is improved, the feeding environment and the reaction environment are isolated, and the reaction can be carried out in a closed environment.

Problems solved by technology

[0002] In the production process of catalytic new materials, powder material transportation is generally completed by air flow or manual transportation, and granular material transportation is generally completed by belt or bucket elevator. The disadvantage of manual material transportation is low production efficiency and labor. The strength is high, and the bucket elevator transportation is easy to cause the material to be broken

[0003] For the process of preparing high-purity aluminum hydroxide by the aluminum alcohol method, the reaction of alcohol and aluminum is generally fed into the reactor manually, and the air is isolated for reaction in a closed environment. For each reaction kettle, the reactor needs to be purged and cleaned. This feeding method is labor-intensive, inefficient, highly dangerous, and cumbersome to operate. As the production costs of enterprises continue to increase, enterprises are facing transformation and upgrading, and machine substitutions. Only through mechanization and automation technology can the labor force be transformed from heavy manual labor Freed from the middle, improve production efficiency

For this reason, many production enterprises have adopted material conveying devices instead of manual handling, which has solved the problems of low production efficiency, high labor intensity and high production cost of manual handling.

[0004] The continuous aluminum alcohol method to prepare high-purity aluminum hydroxide technology needs to be carried out at a certain temperature and in a closed environment due to the particularity of the reaction and raw materials; in the continuous reaction, the feeding environment needs to be isolated from the reaction environment, and the feeding is granular Or flake metal aluminum, the conventional feeding method cannot meet the isolation requirements
