Detailed Description
The present utility model will be described in detail with reference to specific examples. The following examples will assist those skilled in the art in further understanding the present utility model, but are not intended to limit the utility model in any way. It should be noted that variations and modifications could be made by those skilled in the art without departing from the inventive concept. These are all within the scope of the present utility model.
As shown in fig. 1, the secondary iron removing device for the aluminum nitride ceramic slurry comprises a stirring barrel 5, a pipeline 7 and a drying tower 11, wherein the ceramic slurry in the stirring barrel 5 is uniformly stirred under the action of a stirring motor 1, a stirring shaft 2 and stirring blades 4, and two strong magnetic rods 3 are arranged in the stirring barrel 5 to perform primary iron removal on the ceramic slurry to adsorb impurity iron powder.
The ceramic slurry having undergone primary iron removal in the stirring tank 5 is sucked into the drying tower 11 by the circulation pump 6. Through offer three opening 12 on adopting the pipeline 7 of stainless steel material, place strong magnet piece 10 in opening 12 to sealed tight through sealing member 8 and fixed cover 9, when the ceramic slurry through the one-level deironing flows in pipeline 7, the strong magnet piece 10 of putting into can carry out the second grade deironing to the ceramic slurry, and impurity iron powder in the ceramic slurry is adsorbed on strong magnet piece 10, thereby reaches the effect of getting rid of impurity iron powder.
After the ceramic slurry flows into the drying tower 11 for spray drying through primary iron removal and secondary iron removal, the sealing element 8 and the fixing sleeve 9 on the pipeline 7 can be removed, the strong magnet block 10 in the opening 12 is taken out, the impurity iron powder is found to be fully adhered on the strong magnet block 10, and after the impurity iron powder on the strong magnet block 10 is cleaned, the impurity iron powder is reloaded into the pipeline 7 for the next ceramic slurry to adsorb the impurity iron powder.
