Detailed Implementation

[0016] The embodiments of this utility model are further described below with reference to the accompanying drawings. Example

[0017] like Figures 1 to 3As shown; a centrifugal device for the preparation of stannous octoate includes a fixed frame 1, a housing 2, and a centrifugal screening device 3. The housing 2 and the centrifugal screening device 3 are mounted on the fixed frame 1, and the centrifugal screening device 3 is disposed inside the housing 2. The centrifugal screening device 3 includes a power motor 31, a lower circular plate 32, an upper circular plate 33, a feed pipe 34, a liquid ring 35, a vortex-type guide plate 36, a vortex-type baffle 38, a vortex-type filter plate 39, and a connecting column 312. The power motor 31 is mounted on the fixed frame 1 and The power rod is connected to the lower circular plate 32, and the feed pipe 34 is connected to the center of the upper circular plate 33. The liquid ring 35, the vortex-shaped guide plate 36, the vortex-shaped baffle 38, and the vortex-shaped filter plate 39 are connected between the lower circular plate 32 and the upper circular plate 33. The vortex-shaped guide plate 36 is disposed inside the liquid ring 35, and the liquid ring 35 has several liquid guiding holes 37. The vortex-shaped baffle 38 has crossbars bent at both ends, and the vortex-shaped filter plate 39 is connected to two crossbars at both ends. Several connecting posts 312 are connected. Between the lower circular plate 32 and the upper circular plate 33, a plurality of liquid outlet holes 311 are provided on the lower circular plate 32 between the vortex-shaped baffle 38 and the vortex-shaped filter plate 39; two vortex-shaped limiting platforms 310 are respectively provided on the lower circular plate 32 and the upper circular plate 33, and the two vortex-shaped limiting platforms 310 are respectively provided on both sides of the vortex-shaped filter plate 39; the vortex-shaped baffle 38 is inclined on the side near the vortex-shaped filter plate 39; a V-shaped material distribution ring 313 is connected to the circumferential surface of the lower circular plate 32; the vortex... The vortex filter plate 39 is wrapped with a sealing strip, and the two ends of the vortex baffle 38 have sealing grooves for the sealing strip to be inserted. The outer shell 2 includes an upper material guide shell 21, a lower liquid guide shell 22 and an L-shaped annular groove 23. The upper material guide shell 21 and the lower liquid guide shell 22 are connected to the fixed frame 1. The upper edge of the lower liquid guide shell 22 is bent to the two ends of the V-shaped material distribution ring 313. A drain pipe is connected to the lower liquid guide shell 22. The L-shaped annular groove 23 is connected to the lower liquid guide shell 22 and is located below the upper material guide shell 21.

[0018] The lower circular plate 32 is rotated by the power motor 31, and the lower circular plate 32 drives the upper circular plate 33 to rotate via the connecting column 312. Simultaneously, the liquid ring 35, vortex-shaped guide plate 36, vortex-shaped baffle 38, and vortex-shaped filter plate 39 between the upper circular plates 33 rotate synchronously. The reaction liquid and crystals are introduced into the liquid ring 35 through the feed pipe 34. At this time, the rotating vortex-shaped guide plate 36 provides centrifugal force to the reaction liquid and crystals, causing them to enter the area of ​​the vortex-shaped filter plate 39 through the liquid guide hole 37. The reaction liquid is then filtered out by the vortex filter plate 39 and enters the vortex baffle. Between plate 38 and vortex filter plate 39, the reaction liquid adheres tightly to the inner wall of vortex filter plate 38 due to centrifugal force. The inclined inner wall provides a guiding direction, causing the reaction liquid to concentrate towards the outlet hole 311 and be discharged into the lower liquid guide shell 22 through the outlet hole 311. Finally, it is discharged through the drain pipe. Meanwhile, the material crystals move along the vortex filter plate 39 due to centrifugal force until they are discharged and splashed onto the upper material guide shell 21, and finally fall into the L-shaped annular groove 23 for discharge. The purpose of positioning the vortex filter plate 39 by the vortex limiting stage 310 is to prevent displacement due to centrifugal force and the centrifugal thrust of the reaction liquid.
