Abstract

The invention discloses a reaction kettle for preparing nano calcium carbonate. The reaction kettle includes a cylinder body and a cylinder cover, the cylinder body is covered with the cylinder cover, the cylinder cover is provided with a carbon dioxide gas inlet and a motor, the cylinder is externally provided with a hollow clamping sleeve, the clamping sleeve covers the surface of the outer wall of the cylinder body besides the bottom of the cylinder body, the upper portion of the clamping sleeve is provided with a cooling medium inlet pipe, he lower portion of the clamping sleeve is provided with a cooling medium outlet pipe, the inner wall of the clamping sleeve is provided with a first baffle plate and a second baffle plate, the first baffle plate and the second baffle plate are arranged on two inner walls in the clamping sleeve respectively and arranged in a staggered mode, and pores are formed between the inner wall of the clamping sleeve and the first baffle plate and between the inner wall of the clamping sleeve and the second baffle plate. According to the reaction kettle, by further improving the clamping sleeve, reaction heat can be effectively removed, the use of cooling mediums is reduced, and huge waste of the cooling mediums is avoided.

Description

technical field [0001] The invention relates to the field of nano powder preparation, in particular to a reaction kettle for preparing nano calcium carbonate. Background technique [0002] Nanopowder is also called nanoparticle, which generally refers to ultrafine particles with a size between 1-100nm. Some people call it ultrafine particles. Its scale is larger than atomic clusters but smaller than ordinary particles. Calculated according to its size, assuming that the size of each atom is 1 angstrom, then the number of atoms it contains is between 1000 and 1 billion. It is smaller than a normal biological cell and comparable in size to a virus. The shapes of nanoparticles are spherical, plate-shaped, rod-shaped, horn-shaped, sponge-shaped, etc. The components of nanoparticles can be metals, oxides, or other various compounds. Nano-calcium carbonate is a kind of nano-powder, which includes ultra-fine calcium carbonate and ultra-fine calcium carbonate, which are new high-...
