Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1

[0023] like Figure 1~Figure 2 As shown, this embodiment proposes:

[0024] A nano-slurry separator for producing ultrafine zirconium silicate powder comprises a shell 1, one side of the shell 1 is fixedly connected with a feed pipe 2 for convenient entry of zirconium silicate slurry, a rotating shaft 3 is rotatably installed at the center of the inner cavity of the shell 1, a spiral blade 4 is fixed on the outer wall of the rotating shaft 3, a liquid guide tube 5 is fixed on the top of the rotating shaft 3, the top of the liquid guide tube 5 passes through the top wall of the shell 1 through a leakproof bearing and is fixed with a rotating joint 6, a fine material outlet pipe 7 is fixed on the top of the rotating joint 6, a No. 1 gear 8 is fixed on the outer wall of the liquid guide tube 5, and the No. 1 gear 8 is meshedly connected with a No. 2 gear 9, A driving motor 10 is fixed to the top wall of the shell 1, and a power shaft on the top of the driving motor 10 is fixedly connected to the bottom axis position of the No. 2 gear 9. A protective shell 11 is fixed to the top wall of the shell 1 corresponding to the position of the driving motor 10 and the liquid guide tube 5. The protective shell 11 is fixedly connected to the fine material outlet pipe 7. A filtering mechanism 12 is fixedly connected to the bottom end of the shell 1.

[0025] In this embodiment, the feed pipe 2 is used to introduce zirconium silicate slurry into the shell 1, and the drive motor 10 drives the first gear 8 to rotate through the second gear 9. The first gear 8 drives the liquid guide tube 5 to rotate during the rotation. The liquid guide tube 5 can drive the rotating shaft 3 and the spiral blade 4 to rotate during the rotation, thereby driving the zirconium silicate slurry to rotate in the shell 1.

[0027] In this embodiment, the guide grooves 18 provided at both ends of the rotating shaft 3 can ensure that the top slurry after centrifugation can be discharged through the fine material outlet pipe 7, and the bottom slurry after centrifugation can smoothly enter the filtering mechanism 12. The feed pipe 2 is arranged along the tangential direction of the shell 1, so that the slurry can rotate along the inner wall of the shell 1 when entering the shell 1, thereby generating centrifugal force, and the centrifugal force generated by the rotating shaft 3 and the spiral blades 4, double centrifugation, so that the slurry separation is more complete, ensuring the separation effect.
