Description

Technical Field

[0001] The utility model relates to the field of calcium carbonate preparation experiments, in particular to a light calcium carbonate preparation experiment device with an anti-blocking function. Background Art

[0002] In the process of conducting experimental research on the preparation of light calcium carbonate by carbonization method, the main experimental conditions investigated include digestion temperature, stirring intensity, carbon dioxide ventilation rate, digestion time and other parameters. Through the integrated experimental device, the condition parameters of the entire preparation process can be explored and optimized. However, this kind of continuous experimental device is usually blocked by calcium deposition in the liquid phase because of the large local resistance of elbows and filters in various pipes, which may affect the normal operation of the experimental device. The high-energy vibration characteristics of ultrasound to remove precipitation have been applied in some special descaling fields, but have not yet been applied in the experimental device for the preparation of light calcium carbonate. In addition, previous research or applications using ultrasonic effects to remove precipitation have all involved immersing ultrasonic probes in the liquid phase. There is no direct compounding of piezoelectric ceramic materials onto pipes to achieve in-situ ultrasonic generation to remove precipitation. This experimental device is sufficiently innovative.
