The outer sides of the four turntables 20 are fixedly connected to torsion springs 21, and the outer ends of the four torsion springs 21 are fixedly connected to the inner wall of the housing 4. The four torsion springs 21 are respectively sleeved on the outside of the four rotating shafts 3 12; The baffle rods 22 are provided in four numbers, and the four baffle rods 22 are all fixedly connected to the inner wall of the cylinder 1, and the four baffle rods 22 are respectively in contact with the four spoiler plates 13; The four connecting rods 18 and the four levers 19 are evenly distributed in a circular shape. In this embodiment, spoiler 13, spoiler 2 14 and auxiliary components are designed.

Among them, in order to achieve the purpose of increasing the stirring quality, the present device is implemented by the following technical scheme: the toggle component includes: a cavity 24, the cavity 24 is opened on the spoiler 13, the top and bottom of the cavity 24 are both provided with through grooves 25, two slots 26 are opened between the rotating shaft 10 and the spoiler 13, and two rubber sleeves 27 are fixedly connected inside the cavity 24; a baffle 28, which is provided with two, the two baffles 28 are respectively slidably embedded in the two rubber sleeves 27, the outer ends of the two baffles 28 extend to the inside of the two through grooves 25 respectively, and two connecting blocks 29 are fixedly connected inside the cavity 24, the two connecting blocks 29 are both provided with through holes, and the inner sides of the two baffles 28 are fixedly connected with ropes 30, the ends of the two ropes 30 are respectively fixedly connected to the top and bottom of the shell 4, and the two ropes 30 pass through the two through holes and the two slots 26 respectively; a guide rod 31, which is provided with two, the two guide rods The rods 31 are fixedly connected to the inside of the second cavity 24, and the two ropes 30 are respectively in contact with the two guide rods 31. The top and bottom of the rotating shaft 3 12 are fixedly connected with sleeves 32, and the two ropes 30 pass through the two sleeves 32 respectively; there are two guide blocks 33, which are respectively fixedly connected to the outsides of the two sleeves 32, and the two guide blocks 33 are respectively in contact with the two ropes 30; there are two springs 34, which are respectively sleeved on the outside of the two ropes 30, and the outer ends of the two springs 34 are respectively fixedly connected to the inner sides of the two baffles 28, and the inner ends of the two springs 34 are respectively fixedly connected to the outer sides of the two connecting blocks 29, and the ropes 30 are in sliding contact with the guide rods 31 and the guide blocks 33. The design of the spoiler assembly can block the through slot 25, so that the solution can flow through the through slot 25 for a while and cannot flow through for a while, so that the stirring quality can be increased when the solution is stirred in a small range; In order to facilitate installation, the device is implemented by the following technical solution: a plurality of mounting holes 35 are provided on the cover plate 2, a sealing ring 36 is fixedly connected to the bottom of the cover plate 2, and the mounting holes 35 can facilitate installation of the device; Among them, in order to achieve the purpose of reducing wear, the present device adopts the following technical solutions: the rotating shaft 1 8 is connected to the cover plate 2 through a sealed bearing, the rotating shaft 2 10 is connected to the support rod 9 through a sealed bearing, and the rotating shaft 3 12 is connected to the cylinder 1 and the outer shell 4 through a sealed bearing. The connection through the sealed bearing can not only reduce wear but also prevent water from entering the bearing.
[0019] The use process of the present invention is as follows: first, add the solution to be crystallized into the crystallization kettle, then put the device into the crystallization kettle from the feed port until the sealing ring 36 on the cover plate 2 contacts the crystallization kettle, so that the lower half of the cylinder 1 can be immersed in the solution, and then use bolts to install the cover plate 2 on the crystallization kettle; When it is necessary to cool the solution, the motor 7 is controlled to work. The operation of the motor 7 drives the rotation of the first rotating shaft 8. Then, under the action of the planetary speed reducer 5, the second rotating shaft 10 can be rotated. Moreover, the rotation speed of the second rotating shaft 10 is much higher than that of the first rotating shaft 8. The rotation of the second rotating shaft 10 drives the rotation of the impeller 11. The rotation of the impeller 11 can transport the solution upward. In this way, the solution can flow upward along the inner wall of the cylinder body 1, then flow out from the top of the cylinder body 1 and return to the crystallization kettle. Thus, the circulation flow of the solution can be realized. At the same time, the cooling fan 15 is controlled to work. In this way, the cold air can enter the first cavity 23 through the first pipeline 16. When the solution flows upward along the inner wall of the cylinder body 1, it can be cooled. In addition, a plurality of second pipelines 17 are designed. In this way, the cold air in the second cavity 24 can also be blown onto the solution through the second pipelines 17, thereby realizing secondary cooling; The rotation of the first rotating shaft 8 can cause the rotation of the four dial rods 19. The rotation of the four dial rods 19 can move the four connecting rods 18. And the connecting rods 18 are fixedly connected to the first spoiler 13. When the dial rods 19 rotate to move the connecting rods 18, the first spoiler 13, the second spoiler 14 and the third rotating shaft 12 can rotate around the third rotating shaft 12 as the rotation axis. When the third rotating shaft 12 rotates, it can also cause the rotation of the turntable 20. The rotation of the turntable 20 can cause the torsion spring 21 to undergo elastic deformation. In this way, when the dial rods 19 are not in contact with the connecting rods 18, under the action of the rebound of the torsion spring 21, the first spoiler 13, the second spoiler 14 and the third rotating shaft 12 can reverse and reset. When the first rotating shaft 8 rotates to drive the continuous rotation of the four dial rods 19, the first spoiler 13 and the second spoiler 14 can continuously rotate back and forth. When the solution flows upward along the inner wall of the cylinder body 1, it can not only change the flow direction and path of the solution, but also have the effect of slightly stirring the solution. When the solution is cooled, the solution can be evenly cooled. Thus, it can ensure that the temperature of the solution drops evenly, avoid local overheating or overcooling, is conducive to the formation of good crystal forms and particle size distributions, and further promotes the crystallization and precipitation of solutes; Since the two ropes 30 in each toggle assembly are fixedly connected to the shell 4, when the toggle rod 19 toggles the connecting rod 18 to rotate the spoiler 1 13, the spoiler 2 14 and the rotating shaft 3 12 with the rotating shaft 3 12 as the rotating axis, the rope 30 can be pulled, so that the two ropes 30 can pull the two baffles 28 to move toward the middle, and the two springs 34 are compressed. When the toggle rod 19 is separated from the connecting rod 18, that is, when the spoiler 1 13, the spoiler 2 14 and other components are reversed, the two baffles 28 can move outward under the action of the rebound of the two springs 34. When the spoiler 1 13 rotates back and forth continuously, the two baffles 28 on the spoiler 1 13 can also continuously stretch and move, thereby allowing the solution to flow through the through groove 25 for a while and not flow through for a while. In this way, the stirring quality can be increased when the solution is stirred in a small range. In this way, when guiding the solution to flow, not only can the solution be evenly cooled, but also the solute can be evenly distributed in the solution, which can avoid the situation where the local concentration is too high or too low.

Any person skilled in the art may modify the present invention by using the above technical solutions or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement made according to the technical solution of the present invention belongs to the scope of protection claimed by the present invention.
