Device for producing low-density aluminum fluoride by using fluosilicic acid

Abstract

The invention relates to a device for producing low-density aluminum fluoride by using fluosilicic acid. The device comprises a shell, wherein the bottom surface of the shell is opened, three gear belts are fixedly mounted in the shell, the central lines of the gear belts are vertical to the surface of the shell and are connected through a gear conveying belt, and the gear conveying belt is a double-surface gear conveying belt; two first gears are fixedly mounted in the shell, the central lines of the first gears are vertical to the back surface of the shell, the first gears are respectively located on two sides of the gear conveying belt and are engaged with two sides of the gear conveying belt, and first bevel gears are respectively fixedly mounted in front of the first gears; and vertical rotating shafts are mounted on two sides in the shell through bears, and first bevel gears are respectively fixedly mounted at the upper ends of the vertical rotating shafts. Furthermore, a singlechip microcomputer and a timer can be mounted in the shell, a motor is connected with the circuit of the single chip microcomputer, the timer is connected with the circuit of the single chip microcomputer, and the working time of the motor can be set through the timer, so that the quantitative addition of the raw materials can be realized, the whole process relatively approaches to the intelligentautomation, and the automatic production progress of chemical products can be promoted.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, in particular to a device for producing low-density aluminum fluoride from fluorosilicic acid. Background technique [0002] The direct method of fluosilicic acid to produce aluminum fluoride has achieved great success abroad. Since AlF3 is stable in HF environment and has strong L acidity, it is the preferred material for F / Cl exchange reaction. The catalytic reactivity of AlF3 is closely Correlation, and high specific surface area is the premise of increasing catalytic activity. Therefore, the preparation of aluminum fluoride with high specific surface area and low density has attracted attention and attention. At present, people usually need template agent and other raw materials when producing low-density aluminum fluoride, and sometimes a mixture of two raw materials needs to be added. At present, the two raw materials are usually mixed and added to the reaction tank through a sti...

Problems solved by technology

At present, people usually need template agent and other raw materials when producing low-density aluminum fluoride, and sometimes a mixture of two raw materials needs to be added. At present, the two raw materials are usually mixed and added to the reaction tank through a stirring device, but this method is relatively cumbersome. , after the event, workers need to control the addition of mixed raw materials, which is labor-intensive and labor-intensive
