Spray pool capable of monitoring stability of MnZn ferrite slurry, and monitoring method thereof

Abstract

The invention is applicable to the technical field of ferrites, and provides a spray pool capable of monitoring stability of MnZn ferrite slurry, and a monitoring method of the spray pool. The spray pool comprises a slurry pool for containing slurry, and is characterized by further comprising a PH detector, a conveying pipe and a return pipe, wherein the PH detector is fixed on the outer wall of the slurry pool, the detection end of the conveying pipe penetrates through the outer wall and extends into the slurry pool, the conveying pipe and the return pipe are fixedly connected to the outer wall of the bottom of the slurry pool and communicate with the interior of the slurry pool, the PH value in the slurry pool is detected through the PH detector, and the dosage of a dispersing agent in the slurry is judged according to the PH value. According to the invention, when the detected PH value is within an approved interval, it shows that the slurry meets the requirement and can be conveyedto the outside through the conveying pipe to be subjected to subsequent spray granulation; and when the detected PH value is not within the approved interval, it shows that the amount of the dispersing agent is too large or too small, so that the slurry can be conveyed to the sanding process through the return pipe.

Description

technical field [0001] The invention belongs to the field of ferrite technology, in particular to a spray tank capable of monitoring the stability of MnZn ferrite slurry and a monitoring method thereof. Background technique [0002] Due to the shrinkage ratio and charging ratio that have been set during the molding mold design, in order to make both the blank and the sintered magnetic core meet the process requirements such as size, density, mechanical strength, appearance, etc., the loose packing ratio of the powder must be stabilized at an appropriate If the range is too high or too low, it will cause a series of problems such as blank molding, no adjustment allowance for density, cracking, and no strength. The sintered product will also have problems such as excessive size, poor mechanical strength, and cracking. [0003] At present, it is a common and troublesome problem in the powder industry that the bulk ratio fluctuates between batches, and even fluctuates greatly. A...
