Drying equipment for calcium formate production and use method thereof

Abstract

The invention relates to the field of calcium formate drying, in particular to drying equipment for calcium formate production and a using method thereof, and the drying equipment comprises a base, a drying device, a grading recovery device and a crushing device. According to the drying equipment for calcium formate production, through a special flow direction channel formed among the main drying cylinder, the shielding guide hopper, the material blocking cylinder and the drying outer cylinder, wet materials can be impacted and crushed in multiple directions under the influence of hot air flow, meanwhile, the air flow can be in better contact with particles for air drying, and the drying efficiency is improved. Meanwhile, under the cooperation of the second hot-air blower, the problem that the materials fall down and block is solved, the mechanical size is greatly reduced, installation is convenient, hot air flow is conveyed to the discharging slope end of the connecting pipe through the second hot-air blower, and under the action of air pressure, the materials can be discharged rapidly. Hot air carrying particles in the drying outer cylinder is rapidly conveyed into the separation cabin through the connecting pipe, meanwhile, the particles can be secondarily heated, and falling wet materials collide with the inner wall of the main drying cylinder to be scattered through rotation of the movable fan.

Description

technical field [0001] The invention relates to the field of calcium formate drying, in particular to a drying equipment for calcium formate production and a use method thereof. Background technique [0002] Calcium formate, also known as calcium formate, is a calcium salt containing formic acid. Calcium formate can be used as a sour agent instead of citric acid and fumaric acid, and can replace calcium propionate as an antiseptic and antifungal agent. It is suitable for all kinds of animals Used in feed, it has the functions of preventing diarrhea and diarrhea, and helping feed digestion and absorption. It is a widely used chemical product. The solubility of calcium formate does not change much with the increase of temperature. The main method of producing calcium formate is to use dilute formic acid and carbonic acid. Calcium or calcium hydroxide reacts to generate calcium formate solution, which is filtered to remove insoluble matter, the filtrate is concentrated and crys...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of calcium formate production with drying equipment and using method thereof, to solve the friction force between the large particle raw material proposed in the above-mentioned background technology and the inner wall of the feed pipe increases, thereby easily blocking the drying pipe, and along with With the extension of the pipeline, the temperature of the internal airflow is gradually reduced, the drying efficiency of the material is gradually reduced, and the mechanical cost of the ordinary pulverizer is relatively high, which indirectly increases the drying cost.
