Technical Field
[0001] The utility model relates to the technical field related to the preparation of cobalt sulfate crystals, in particular to a reaction kettle for the preparation of high-purity cobalt sulfate crystals. Background Art
[0002] Cobalt sulfate crystals are usually produced by chemically reacting or heating cobalt metal to produce cobalt oxide, then reacting the cobalt oxide with sulfuric acid to produce a cobalt sulfate solution, and then evaporating and concentrating the resulting solution, cooling and crystallizing it, and centrifuging and dehydrating it to finally obtain cobalt sulfate. The chemical reactions are all completed in a reactor, so a reactor for preparing high-purity cobalt sulfate crystals is used;
[0003] In a reactor for preparing cobalt sulfate based on a continuous process disclosed in publication number CN218307969U, various raw materials are sequentially fed into a plurality of reaction tanks through a feed port in a certain proportion. After the various raw materials are fully reacted in the reaction tanks, the obtained cobalt sulfate solution is fed into a group of evaporation tanks through a pipeline. The evaporation tank heats and evaporates the cobalt sulfate solution, and the steam enters the reaction chamber through the pipeline to increase the temperature in the reaction chamber and accelerate the reaction speed. When the air pressure in the reaction chamber is too high, the gas with a lower temperature is discharged from the exhaust port on the side wall at the bottom of the reaction chamber. When the cobalt sulfate solution in the evaporation tank reaches saturation, the evaporation tank stops heating, and the coolant is transported to the cooling pipeline through the cooling interface to reduce the temperature of the cobalt sulfate solution. As the temperature of the cobalt sulfate solution decreases, the solubility of cobalt sulfate decreases, and part of the cobalt sulfate condenses into solid crystals and precipitates. The precipitated crystals and the remaining cobalt sulfate solution are transported to the centrifugal barrel through a pipeline. Since there is a through hole at the bottom of the centrifugal barrel, the cobalt sulfate solution enters the filter barrel through the through hole, and the cobalt sulfate crystals remain in the centrifugal barrel. The motor is started to drive the centrifugal barrel to rotate for centrifugal dehydration to obtain the required cobalt sulfate, which is then taken out from the material taking door. The splash plate prevents liquid splashing during the centrifugation process. The cobalt sulfate solution in the filter barrel is input into another set of evaporation tanks through a pipeline to continue evaporation and concentration. The extraction rate can be improved by cross-evaporating and concentrating the cobalt sulfate solutions in the two sets of evaporation tanks.
[0004] However, the above scheme still has the following problems during use: when in use, after the reaction materials are placed in a reactor, a cobalt sulfate solution is obtained by self-reaction, and the reaction efficiency is low. After sufficient reaction in the reactor, the obtained cobalt sulfate solution is input into a group of evaporation tanks through pipelines. The evaporation tank heats and evaporates the cobalt sulfate solution, and the centrifugal barrel rotates for centrifugal dehydration to obtain the required cobalt sulfate. During the use of the centrifugal barrel, crystals will remain on the barrel wall. In order to facilitate subsequent use, the centrifugal barrel needs to be cleaned and prevented from being blocked.
[0005] Therefore, we proposed a reaction kettle for preparing high-purity cobalt sulfate crystals in order to solve the above-mentioned problems. Utility Model Content
