Description

Technical Field

[0001] The utility model relates to the field of rare earth oxalate processing, in particular to a device for washing and filtering rare earth oxalate. Background Art

[0002] Rare earth oxalate plays a key role in dissolution and complexation in the separation process of rare earth elements. Rare earth oxalate needs to be washed before calcination to remove impurities in the rare earth oxalate, and then filtered to reduce the moisture in the rare earth oxalate. Finally, the washed and filtered rare earth oxalate is transported to the calcination. In the past, rare earth oxalate was transported by manually pushing a washing and filtering box equipped with wheels. However, the number of transfers is large, the distance is long, and the single transfer is heavy. This transportation method is time-consuming and labor-intensive, and has high labor intensity, which affects work efficiency. In the use of existing washing and filtering boxes, usually manual pushing of the washing and filtering box equipped with wheels is used for transportation.

This transportation method is time-consuming and labor-intensive, and has high labor intensity, which affects work efficiency. Therefore, we propose a device for washing and filtering rare earth oxalate to solve the above-mentioned problems. Utility Model Content
