Description

Technical Field

[0001] The invention relates to the technical field of phosphor waste oxides, in particular to a phosphor waste oxide dissolution co-precipitation screening device. Background Art

[0002] The phosphor waste oxide dissolution co-precipitation screening device usually consists of a dissolution device, a screening device, a drying device and a control system.

[0003] The patent with patent announcement number CN112853098B relates to a fluorescent powder waste oxide dissolution co-precipitation screening device, including a dissolution mechanism, a protective cover, a precipitation mechanism, a drying mechanism and a screening mechanism. The dissolution mechanism is installed above the precipitation mechanism, and a transparent protective cover is arranged on the outside of the dissolution mechanism. The right end of the precipitation mechanism extends to the inside of the drying mechanism, and the drying mechanism and the screening mechanism are interconnected; the dissolution mechanism includes a spraying component, a lifting component, a multi-layer dissolution component and a bracket. The four corners of the lower end of the spraying component are fixedly connected with the bracket by bolts. The fluorescent powder waste is retained by the filter screen plate, and its dissolution is accelerated by flushing. The dissolved liquid drips into the sedimentation box, and the insoluble minerals are left in the filter screen plate, which can not only accelerate the dissolution but also reduce the impurity removal process.

[0004] In the above patent, a filter screen is used to retain fluorescent powder waste, and its dissolution is accelerated by flushing. The dissolved liquid drips into a sedimentation box, and the insoluble minerals are retained in the filter screen.
