Description

Technical Field

[0001] The invention relates to the technical field of magnesium nitrate production, in particular to a granulating device for magnesium nitrate production. Background Art

[0002] Magnesium nitrate is an inorganic substance with the chemical formula Mg(NO3)2, colorless monoclinic crystals or white crystals. It is easily soluble in hot water, cold water, methanol, ethanol, and liquid ammonia. Its aqueous solution is neutral. It can be used as a dehydrating agent, catalyst, wheat ash agent, and catalyst for concentrated nitric acid.

[0003] A granulating device is required for the production of magnesium nitrate. The current granulating device for the production of magnesium nitrate requires the use of a binder. The binder is very viscous and cannot be sprayed out evenly, and is prone to forming larger particles. The binder can easily cause the nozzle to become clogged, and the binder cannot enter the granulator, making it impossible to granulate.

[0004] For example, a granulating device for magnesium nitrate production disclosed in announcement number CN215506654U achieves the effect that the binder can be evenly sprayed out for easy granulation by arranging a storage box, a rotating rod, a stirring rod, an inner box, a turntable, a fixed pipe, a discharge pipe, a connecting pipe, a support pipe and a nozzle. The valve is opened, and the binder is poured into the storage box through the feed pipe. The heating plate heats the binder under the action of the power device, the rotating rod rotates under the action of the power device, the rotating rod drives the stirring rod to rotate, and the stirring rod drives the scraper to rotate. The scraper can remove the binder on the inner wall of the storage box. Scraping can ensure that the adhesive will not stick together, hold the first handle, drive the first handle to open the first sealing cover, hold the second handle, drive the second handle to open the second sealing cover, put the magnesium nitrate powder into the inner box, hold the second handle, drive the second handle to close the second sealing cover, the inner box rotates under the action of the power device, and the inner box drives the powder to rotate, and the discharge pipe sucks the adhesive inside the storage box into the turntable under the action of the power device, and then enters the support pipe through the connecting pipe, and then sprays it out through the nozzle, so as to evenly spray the adhesive and facilitate granulation.

[0005] However, the device cannot stir the magnesium nitrate solution evenly during use, resulting in uneven local concentration distribution, causing differences in magnesium nitrate crystallization, and unable to ensure the consistency of the particle composition after granulation, thus affecting the granulation quality.

[0006] For this reason we urgently need to provide a kind of magnesium nitrate production granulating device. Summary of the invention

[0007] The object of the present invention is to provide a granulating device for producing magnesium nitrate to solve the problems raised in the above-mentioned background technology.
