Device for spraying iodine

The utility model relates to an iodine spraying device, which comprises a trolley, an agitator tank, a heat insulation barrel, and an iodine spraying module, the agitator tank, the heat insulation barrel and the iodine spraying module are respectively arranged on the trolley, a drain pipe of the agitator tank is connected with an organic glass tube of the heat insulation barrel, and a return pipe and a drain pipe of the heat insulation barrel are respectively connected with an overflow valve of the iodine spraying module and the input end of a diaphragm metering pump. The agitator tank is arranged on the high position, which ensures that the agitator tank has a height difference with the heat insulation barrel so that the solution can be successfully transferred into the heat insulation barrel. The agitator tank is used to evenly agitate the pairing solution, the heat insulation barrel is used to make a temperature rise to the liquid to ensure that the temperature of the solution is 40 DEG C or so, and the main effect of the iodine spraying module is to quantificationally and evenly spray the solution on the salt conveyed through a conveyer belt. The iodine spraying device realizes the quantificational iodine addition to the batch salt, has good iodine addition effect, can change the iodine content of the salt and the iodine spraying flow at any time according to the requirement of the production, can adapt to the need of different production scales, and has reasonable structure, reliable performance, and simple and convenient operation.
