Description

Technical Field

[0001] The invention relates to the technical field of nano material preparation, in particular to a device for preparing emulsified nano calcium carbonate. Background Art

[0002] Nano calcium carbonate is an inorganic compound, and emulsified nano calcium carbonate is the product of nano calcium carbonate after emulsification. Emulsified nano calcium carbonate involves many fields such as industry, daily chemicals, and medicine. In order to evenly disperse nano calcium carbonate particles in a liquid medium to form a stable emulsion, an emulsified nano calcium carbonate preparation device is often used for processing;

[0003] The stirring emulsification equipment mainly includes a tank body for holding materials, with a feed port and a discharge port on the tank body. The feed port is used to add nano calcium carbonate raw materials, emulsifiers and solvents, etc. The internal agitator is usually composed of a motor, a stirring shaft and a stirring paddle. The rotation of the paddle blades drives the material to circulate, and the discharge port is used to discharge the prepared emulsified nano calcium carbonate;

[0004] For the existing emulsified nano-calcium carbonate preparation device, firstly, the stirring emulsification mainly relies on the rotation of the stirring paddle to mix the nano-calcium carbonate particles with the liquid medium. The nano-calcium carbonate particles are easy to agglomerate and cannot be well dispersed into fine particles, resulting in uneven particle size distribution in the emulsion after emulsification and poor emulsion stability. Secondly, after the heating process of the reaction tank is completed, the heat carried by the hot reaction liquid will be dissipated with the heat dissipation of the reaction tank wall and the ventilation of the ventilation system. In the preparation process of emulsified nano-calcium carbonate, waste heat will be generated in multiple links. If this waste heat is not utilized, it will cause a lot of energy waste. Finally, in the preparation process of emulsified nano-calcium carbonate, nano-calcium carbonate is easy to adhere to the inner wall of the reaction tank. The adhesion of nano-calcium carbonate to the inner wall of the equipment will greatly extend the time required for cleaning the equipment, resulting in increased equipment downtime and affecting production efficiency.

[0018] 1. The present invention drives the sun gear to rotate through the stirring motor via the driving gear 1, the driven gear 1 and the transmission shaft. The meshing action of the sun gear, the planetary gear and the gear ring enables the mounting shaft to drive the stirring blade to perform complex movements. Compared with traditional stirring, this stirring method can produce a more complex flow field, so that the nano calcium carbonate particles are subjected to multi-directional shear and impact forces in the solution, effectively reducing the possibility of particle agglomeration, promoting uniform dispersion of particles, and helping to obtain an emulsified system with a more uniform particle size distribution.

The insulation layer can better lock the heat brought by the waste heat, so that the processing tank can maintain a relatively stable temperature environment for a long time, avoiding the heat directly dissipated to the external environment and being wasted, and effectively improving the energy utilization rate.

[0020] 3. The present invention drives the second driving gear to rotate by a cleaning motor, and the second driving gear meshes with the driven rack, thereby driving the rotating ring to rotate. The rotating ring is rotatably connected to the upper middle part of the processing tank, and a plurality of connecting rods are distributed in an annular manner inside the rotating ring.

The inner wall of the processing tank is always kept relatively clean, thereby improving the overall production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
