Rare earth filtration equipment in mother liquor that realizes dehydration of rare earth mother liquor by centrifugal action

Abstract

The invention discloses a filtration device for rare earth in a mother solution for dehydration of a rare earth mother solution by centrifugation. The filtration device structurally comprises a bucket, a lid, a dewatering device and a shell, wherein the bucket is arranged at the center of the top of the lid, the bucket penetrates through the lid, the dewatering device is installed in the shell, and the bucket communicates with the dewatering device. The filtration device has the benefical effects that centrifugal force generated by rotation of a working chamber causes the rare earth mother solution in the working chamber and a small part of the rare earth to be thrown away from an outer wall of the working chamber by centrifugal action caused by the rotation to achieve first separation ofthe rare earth mother solution, a small part of the rare earth in the mother solution which is thrown away is thrown to filter cloth, and by secondary rare earth filtering through the driving filter cloth, the rare earth thrown away from the mother solution is recovered, thereby avoiding waste of resources caused by a traditional dehydration method, and avoiding wear of the mother solution treatment equipment by the rare earth in the mother solution which is thrown away.

Description

technical field [0001] The invention relates to the field of dehydration equipment, in particular to a device for filtering out rare earths in mother liquors which utilize centrifugal action to realize dehydration of rare earth mother liquors. Background technique [0002] After rare earth mining, a large amount of water will be carried, and due to the existence of water, it will be inconvenient for the later use of rare earth. Therefore, it is necessary to dehydrate the rare earth mother liquor after mining, so that the mother liquor and rare earth are separated, which is convenient for the later stage of rare earth resources. Development and utilization, the existing rare earth mother liquor dehydration equipment has the following defects: [0003] In the process of dehydrating rare earth mother liquor by traditional rare earth mother liquor dehydration equipment, due to the high rare earth content in the removed rare earth mother liquor, it is directly discharged into the...

AI Technical Summary

Problems solved by technology

[0003] In the process of dehydrating rare earth mother liquor by traditional rare earth mother liquor dehydration equipment, due to the high rare earth content in the removed rare earth mother liquor, it is directly discharged into the mother liquor treatment equipment, which will cause a part of waste of resources, and the directly discharged mother liquor will be in the later stage. Due to the existence of rare earths during the treatment, it will cause wear and tear to the mother liquor treatment equipment
