[0026] like Figures 1 to 4 As shown, a calcium carbonate precipitation filtering device comprises a filtering container 1, the lower end of the filtering container 1 is fixedly connected to a base 2, the upper end of the filtering container 1 is provided with a feed port 3, the middle part of the lower end of the filtering container 1 is provided with a discharge port 4, the upper end of the filtering container 1 is fixedly connected to a first fixing frame 5, the inner side of the first fixing frame 5 is fixedly connected to a first motor 6, the output shaft of the first motor 6 is fixedly connected to a first rotating shaft 7, one end of the first rotating shaft 7 is sleeved inside the upper end of the filtering container 1; and further comprises a filtering tank 9, the interior of the filtering tank 9 is fixedly connected to a plurality of connecting plates 8, the inner ends of the plurality of connecting plates 8 are fixed to the first The lower end of the feed port 3 is arranged above the filter tank 9 on the outer side of the lower end of a rotating shaft 7; it also includes a drying mechanism, which includes an air outlet 28 arranged inside the filter container 1, and the air outlet 28 is arranged in a ring shape along the inner side of the filter container 1. Two groups of air inlet pipes 29 are sleeved at both ends of the air outlet 28. An inclined plate 17 is fixedly connected to the upper end of the inner part of the filter container 1, and a feed passage 18 is sleeved in the middle of the inclined plate 17. A rotating ring 19 is rotatably connected to the outer side of the lower end of the feed passage 18, and two groups of fixed plates 24 are fixedly connected to the lower end of the rotating ring 19, and rotating blades 25 are fixedly connected to the lower ends of the two groups of fixed plates 24.

[0027] Specifically, Figure 1 and Figure 4As shown, the upper end of the feed channel 18 is fixedly connected to the lower end of the filter tank 9, and a fixed block 10 is fixedly connected to the inner side of the filter container 1, and the fixed block 10 is arranged above the inclined plate 17. One end of the fixed block 10 is fixedly connected to a support arm 11, and the upper end of the support arm 11 is fixedly connected to a hard brush 12, and the hard brush 12 is adapted to the outer side of the filter tank 9.

[0028] During operation, calcium carbonate precipitation is put into the interior of the filter tank 9 from the feed inlet 3, and the first motor 6 is started. The output shaft of the first motor 6 drives the first rotating shaft 7 to rotate. Because the first rotating shaft 7 is fixedly connected to the connecting plate 8, and the connecting plate 8 is fixedly connected to the filter tank 9, the rotation of the first rotating shaft 7 drives the filter tank 9 to rotate. When the filter tank 9 rotates, the water in the calcium carbonate precipitation is thrown out by centrifugal force.

The hot air is then blown out from the air outlet 28 to perform hot air drying on the calcium carbonate precipitate on the matching plate 26. At the same time, the third motor 22 is started to drive the third fixed frame 21 to rotate, and the rotation of the third fixed frame 21 drives the third rotating shaft 23 to rotate. The third rotating shaft 23 drives the rotating ring 19 to rotate synchronously through the transmission belt 20. The rotation of the rotating ring 19 drives the two sets of fixed plates 24 to rotate, and the rotation of the fixed plate 24 drives the rotating The moving blades 25 rotate, and the rotating blades 25 rotate to stir the calcium carbonate precipitate on the matching plate 26, so that the calcium carbonate precipitate is evenly distributed. When the drying operation is completed, the adjusting shaft 27 rotates, and the adjusting shaft 27 drives the matching plate 26 to rotate downward. The matching plate 26 rotates downward, and the dried calcium carbonate is discharged through the discharge port 4, and the evaporated water vapor is discharged from multiple groups of through holes. A drying mechanism is provided, and the stirring of the rotating blades 25 and the hot air blown out from the air outlet 28 cooperate to fully dry the calcium carbonate precipitate in the filter container 1, and the situation where the external calcium carbonate is dried while the internal calcium carbonate is not completely dried will not occur.
