Description
Technical field
The utility model relates to a kind of solution crystallization device, particularly a kind of stannous chloride solution dynamic crystallization device.
Background technology
All the time, in the crystallisation by cooling operation of preparation tin protochloride process, all be to adopt static crystallization mode, promptly be stannous chloride solution to be packed into put into freezer behind the plastic tank, rely on freezer that stannous chloride solution is carried out crystallisation by cooling.Stationary crystallization needs lower Tc (5～10 ℃), long crystallization time (48h), and the product hardness that crystallizes out is big, and reduction ratio is difficulty, and product granularity is inhomogeneous, and outward appearance is bad.Simultaneously the heat transfer efficiency of freezer is low, and it is big to take up room, and hydrochloric acid is very big to the corrosion on freezer equipment and ground, causes that production efficiency is low, cost is high.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of stationary crystallization that stannous chloride solution is original to change dynamic crystallization mode, production efficiency height into, the percent crystallization in massecuite height, the all even stannous chloride solution dynamic crystallization device of having simplified the crystallization Production Flow Chart of tin protochloride crystal particle diameter is to overcome above-mentioned the deficiencies in the prior art part.
The technical scheme that solves the problems of the technologies described above is: a kind of stannous chloride solution dynamic crystallization device, comprise the revolution crystallizer and the refrigeration system that drive by revolution crystallizer drive system, refrigeration system comprises unit cooler, with supporting cooling tower and the buffer tank of unit cooler, described revolution crystallizer is the double cone-shaped equipment applies that has chuck, described cooling tower is communicated with unit cooler by cooling tower inlet channel and cooling tower outlet conduit respectively, unit cooler is communicated with buffer tank by unit outlet conduit and unit water return pipeline respectively, and buffer tank is communicated with the chuck of revolution crystallizer by buffer tank outlet conduit and buffer tank water return pipeline.
The rotating speed of described revolution crystallizer is 2～5r/min.
Described revolution crystallizer inwall is that the salt tolerant acid corrosion material of liner enamel, poly-tetrafluoro or PE is made, and revolution crystallizer outside surface carries out the glass reinforced plastic rotproofing, and revolution crystallizer discharge port also adds lining fluorine dish valve.
Described revolution crystallizer adopts the glass lining double conic rotary drying machine.
The utility model adopts double cone-shaped equipment applies as the revolution crystallizer, promptly be to adopt the dynamic crystallization technology, the tin protochloride concentrated solution of an amount of volume is joined in the revolution crystallizer, start revolution crystallizer and unit cooler, the control stannous chloride solution temperature and the refrigerant temperature difference that is arranged in revolution crystallizer chuck, the rotating speed of crystallizer is controlled in 2～5r/min scope, drop to certain temperature up to solution temperature, crystallization this moment is finished, close refrigeration system, the slurry crystalline substance is put in the whizzer and dries, and promptly gets product through packing again.Revolution crystallizer inwall is salt tolerant acid corrosions such as liner enamel, poly-tetrafluoro, PE, and heat conductivility is material preferably, has accelerated the rate of heat exchange of stannous chloride solution and refrigerant.
The utility model changes original stationary crystallization into dynamic crystallization, also has following beneficial effect:
1, crystalline rate improves greatly, and crystallization time obviously shortens, and it is 48 hours that stationary crystallization needs crystallization time, and the dynamic rotation crystallization only needs 20 hours, and production efficiency obviously raises.
2, the percent crystallization in massecuite of dynamic crystallization further improves.The percent crystallization in massecuite of stationary crystallization method is generally about 55%, and dynamic rotation crystallization process percent crystallization in massecuite on average can reach more than 75%, and this helps further improving the product direct yield.
3, the tin protochloride crystal particle diameter of dynamic crystallization output is even, and outward appearance is better; The product cut size of stationary crystallization output is inhomogeneous, and macrobead is many, and outward appearance is bad.
4, dynamic crystallization has been simplified Production Flow Chart, cancelled extensive works such as tin protochloride concentrated solution warehouse-in, outbound, crystallization fragmentation, so dynamic crystallization technology is lower than stationary crystallization technology labour intensity.
Below, the technical characterictic to the stannous chloride solution dynamic crystallization device of the utility model is further described in conjunction with the accompanying drawings and embodiments.
