Detailed Implementation

[0015] The embodiments of this utility model are further described below with reference to the accompanying drawings.

[0016] Example 1

[0017] like Figures 1 to 3As shown; a filtration device for the preparation of stannous octoate includes a housing 1, a filtration device 2, and a centrifugal motor 3. The filtration device 2 is disposed within the housing 1, and the centrifugal motor 3 is installed within the housing 1 with its power rod connected to the filtration device 2. The filtration device 2 includes an outer filter shell 21, an inner isolation shell 22, a spiral feed bar 23, a liquid outlet 24, a triangular liquid guide tube 25, a quick connector 27, and a feed pipe 29. The inner isolation shell 22 is disposed within the outer filter shell 21. At least one spiral feed bar 23 is connected between the outer filter shell 21 and the inner isolation shell 22. The triangular liquid guide tube 25 is connected to the lower side of the spiral feed bar 23, and the side of the triangular liquid guide tube 25 near the outer filter shell 21 has several liquid outlet holes 26. The quick connector 27 is connected to the top of the outer filter shell 21 and communicates with the triangular liquid guide tube 25. The inner isolation shell 22 has an inlet chamber 210 and an annular centrifugal chamber 212 inside. The inlet chamber 210 and the... A plurality of liquid guiding holes 211 are connected between the annular centrifuge chambers 212. A plurality of liquid outlets 24 communicating with the annular centrifuge chambers 212 are provided on the inner isolation shell 22. The feed pipe 29 is connected to the inner isolation shell 22 and communicates with the inlet chamber 210. The outer shell mechanism 1 includes an upper shell 11, a U-shaped guide channel 12, a bearing 13, an isolation shell 14, a discharge hopper 15, and a connecting rod 16. The upper shell 11 is connected to the discharge hopper 15 through the U-shaped guide channel 12. The top of the upper shell 11... The part is connected to the top of the outer filter shell 21 via bearing 13. The isolation shell 14 is connected to the discharge hopper 15 via several connecting rods 16. The centrifugal motor 3 is installed inside the isolation shell 14. A liquid outlet pipe is connected to the U-shaped guide channel 12. A V-shaped partition ring 28 is connected to the lower side of the outer filter shell 21. The two ends of the V-shaped partition ring 28 are respectively located on both sides of one end of the U-shaped guide channel 12. It includes a connecting pipe and a rotary joint. The rotary joint is connected to the quick connector 27 via the connecting pipe.

[0018] The centrifugal motor 3 drives the filter device 2 to rotate, separating the crystals from the original liquid. The original liquid is thrown onto the inner wall of the upper shell 11 by centrifugal force, flows into the U-shaped guide channel 12, and is discharged through the liquid outlet pipe, while the crystals are discharged through the discharge hopper 15. The filtered liquid enters the inlet chamber 210, the guide hole 211, the annular centrifugal chamber 212, the liquid outlet 24, and the space between the outer filter shell 21 and the inner isolation shell 22 through the feed pipe 29. Under the action of centrifugal force, the filtered liquid adheres tightly to the outer filter shell 21, separating the original liquid from the crystals through the outer filter shell 21. The crystals adhere tightly to the inner wall of the outer filter shell 21 while rotating along the spiral during centrifugation. The feed bar 23 moves downward until it enters the discharge hopper 15 and is discharged. After centrifugal filtration, the centrifugal motor 3 is turned off, and the connecting pipe is connected to the quick connector 27. The centrifugal motor 3 is controlled to rotate at a low speed. The filtered raw liquid is introduced back into the connecting pipe through the rotary connector. The raw liquid is then introduced into the triangular guide pipe 25 through the quick connector 27. The liquid is then discharged through the outlet hole 26 on the triangular guide pipe 25 to rinse the outer filter shell 21. The low speed rotation of the filter device 2 can reduce the filtration speed, so that the crystals on the inner wall of the outer filter shell 21 move synchronously with the raw liquid along the spiral feed bar 23, thereby achieving the purpose of cleaning the crystals on the inner wall of the outer filter shell 21.
