Description

Technical Field

[0001] The utility model relates to the field of sodium stannate preparation, in particular to a sodium stannate preparation crystallization device. Background Art

[0002] Sodium stannate is mainly used in alkaline tin plating and copper plating in the electroplating industry, as well as electroplating and chemical plating of tin alloys, zinc-tin alloys, aluminum alloys and other alloys. It is used as a fire retardant and weighting agent in the textile industry. It is used as a mordant in the printing and dyeing industry. It is also used in glass, ceramics and other industries.

[0003] In the process of preparing sodium stannate, there are some obvious problems. For example, when preparing sodium stannate crystals, general reactors often lack stirring devices, resulting in incomplete chemical reactions, insufficient sodium stannate reaction, and reduced precipitation rate of sodium stannate crystals. Secondly, when stirring, the sodium stannate solution is easily splashed onto the bottle mouth, and the sodium stannate solution is relatively viscous, so it is not easy for the sodium stannate solution to flow down and form a wall. The reactor is also difficult to clean due to the relatively narrow bottle mouth, so the residual impurities will reduce the success rate of sodium stannate crystallization. In order to solve the above problems, we proposed a sodium stannate preparation crystallization device. Utility Model Content

[0024] In this embodiment, two groups of bolt holes 22 are provided on the outer sides of the four groups of bases 21, and bolts 23 are slidably connected to the inner sides of each group of bolt holes 22. Nuts 24 are threadedly connected to the outer sides of each group of bolts 23, and two groups of limiting holes 20 are provided on the outer sides of the opposite ends of the two groups of first stirring plates 11. The base 21 is fixedly connected to the first stirring plate 11 by bolts 23 penetrating the limiting holes 20 and the bolt holes 22.

[0025] Specifically, the first stirring plate 11 can be conveniently fixed to the inner side of the base 21 through the cooperation of the bolt 23 , the bolt hole 22 , the limiting hole 20 and the nut 24 .

[0026] In this embodiment, four stirring columns 12 are symmetrically fixedly connected to both sides of the mounting frame 10 . Two stirring columns 12 form a group transversely, and the ends of the two groups of stirring columns 12 that are far away are rotatably connected to the second stirring plates 13 .

[0027] Specifically, by rotating the second stirring plate 13 connected to the outside of the stirring column 12, the reactants in the crystallization device body 1 can be fully stirred to prevent incomplete chemical reaction from reducing the production success rate of sodium stannate.

[0028] In this embodiment, a circular hole 18 is provided at the ends of the two groups of stirring columns 12 that are away from each other, and a mounting hole 14 is provided at the connection between the mounting frame 10 and the two groups of stirring columns 12.

[0034] It should be noted that the utility model is a sodium stannate preparation crystallization device. The user adds the sodium stannate solution into the crystallization device body 1 from the feed port 5, and then heats and concentrates it to reach a saturated concentration, and then adds an alkaline substance into the crystallization device body 1 from the feed port 5. At this time, the motor 7 is started, and the output end of the motor 7 drives the rotating shaft 8 to rotate. The rotation of the rotating shaft 8 will drive the mounting frame 10 to rotate.

When the first stirring plate 11 needs to be replaced, the bolt 23 can be separated from the nut 24 by rotating the nut 24. At this time, the bolt 23 is pulled out from the inside of the base 21, so that the first stirring plate 11 can be easily pulled out from the inside of the base 21 for replacement, thereby reducing the use cost. When the rotating shaft 8 rotates, it will also drive the cleaning scraper 9 to rotate along the inner wall of the conical cylinder 2, so that the solution droplets splashed to the bottle mouth by the stirring of the sodium stannate solution can be cleaned and scraped off, preventing residual impurities from affecting the production success rate of sodium stannate, which is more practical.
