[0025] Embodiment 1, this embodiment aims to provide a zinc sulfate crystallization mechanism, which is mainly used for evaporation crystallization of zinc sulfate. In the existing zinc sulfate crystallization process, stirring is required in the evaporation tank. Insufficient stirring of the zinc sulfate liquid can easily cause uneven crystallization products, which is not conducive to subsequent use.

[0026] like Figure 1-3 As shown in the figure, a zinc sulfate crystallization mechanism comprises a tank body 1 and a stirring mechanism; an air outlet 2 is provided on the upper part of the side wall of the tank body, and the air outlet 2 is arranged to discharge the gas generated in the evaporation process through the air outlet 2, and a discharge port 3 is provided at the bottom of the tank body, and the crystallized crystals are discharged through the discharge port, and a valve 17 is installed on the discharge port 3; a tank cover 4 is fixedly installed on the top of the tank body 1, an axial hole is provided in the center of the tank cover 4, a bearing is fixedly installed in the axial hole, a feed port 5 is provided on the tank cover 4, and a mounting seat 8 is fixed on the middle part of the upper end of the tank cover 4.

[0027] The stirring mechanism includes a track column 9, a rotating shaft 6, a stirring assembly, a linkage rod 12 and a driving motor 7; the driving motor 7 is fixed on a mounting seat 8, and its output shaft faces downward; four evenly distributed support rods are fixed to the upper end of the track column 9, and the track column 9 is fixed to the center of the lower end of the tank cover 4 through the support rods. An avoidance hole is opened in the center of the track column 9, and the avoidance hole is a through hole that passes through from top to bottom. A cam groove 18 is opened on the outer wall of the track column 9, and a sliding block 15 is slidably mounted in the cam groove 18. The sliding block 15 is fixed on the vertically arranged linkage rod 12. By setting the cam groove 18, the linkage rod 12 can be moved up and down during the rotation of the rotating shaft 6.

[0028] The rotating shaft 6 is vertically arranged in the tank body 1, and the upper end of the rotating shaft 6 passes through the avoidance hole and is rotatably sleeved in the center of the tank cover 4 and is connected to the driving motor 7. Specifically, the upper end of the rotating shaft 6 passes through the avoidance hole and is fixedly sleeved in the bearing and is connected to the output shaft of the driving motor 7 through a coupling. A vertically arranged limit rod 13 is symmetrically fixed in the middle of the outer side wall of the rotating shaft 6. Two limit rods 13 are provided. The connecting seat 10 is limited by the limit rod 13, so that the connecting seat 10 can move up and down relative to the rotating shaft 6, but cannot rotate relative to the rotating shaft 6, thereby ensuring that the rotating shaft 6 drives the connecting seat 10 to rotate.

[0029] The stirring assembly includes a connecting seat 10 and a stirring rod 11. The connecting seat 10 is slidably mounted on the rotating shaft 6. Two groups of stirring rods 11 are symmetrically fixed on the outer wall of the connecting seat 10.

The stability of the connection of the stirring assembly is improved by setting the fixed rod 14.

[0030] Two scrapers 16 are symmetrically arranged in the tank body 1 about the rotating shaft 6. The scrapers 16 are in contact with the inner wall of the tank body 1 and are fixedly connected to the rotating shaft 6 through a connecting rod. By arranging the scrapers 16, the crystals adsorbed on the inner wall of the tank body 1 can be cleaned, thereby preventing the crystals adsorbed on the inner wall from affecting the next crystallization, and effectively maintaining the cleanliness of the tank body 1.

[0031] The working principle of this embodiment is as follows: first, ensure that the valve 17 of the discharge port 3 is closed, the zinc sulfate solution enters the tank body 1 through the feed port 5, the tank body 1 is heated to evaporate and crystallize the zinc sulfate solution in the tank, and at the same time, the drive motor 7 is started, the drive motor 7 drives the rotating shaft 6 to rotate, the rotating shaft 6 drives the stirring rod 11 to rotate, and at the same time, the slider 15 slides in the cam groove 18, driving the linkage rod 12 to move up and down, the linkage rod 12 drives the stirring rod 11 to move up and down, and the connecting seat 10 slides up and down relative to the rotating shaft 6, and different positions inside the tank body 1 are stirred, thereby increasing the stirring range, being able to fully stir the zinc sulfate solution, and making the stirring during the evaporation and crystallization process more uniform, and finally, the crystallized crystals are discharged through the discharge port 3.
