Drying kettle for sodium cyanate production and production process thereof

Abstract

The invention relates to the technical field of chemical production, and discloses a drying kettle for sodium cyanate production and a production process thereof. The drying kettle comprises a heating cavity, wherein a reaction kettle body is fixedly installed in the middle of an inner cavity of the heating cavity; a rotating shaft is movably installed in the middle of the reaction kettle body; and the top of the rotating shaft is fixedly sleeved and connected with a wind wheel. By means of the heating pipe, materials, close to the surface of the heating pipe, in the middle of the inner cavity of the reaction kettle body can be heated at a high temperature, the inside and the outside of the reaction kettle body are enabled to be heated consistently, and the heating effect of the heating cavity is uniform; the surface temperature of the heating pipe is effectively compensated by arranging a grinding heat layer and utilizing friction heat generation between the grinding heat layer and the outer surface of the heating pipe; and by arranging a grinding rod, sodium cyanate crystals are ground into sodium cyanate crystal powder, so that the problems that too many sodium cyanate crystals are separated out at a bottom end paddle in an existing drying kettle, the crystal blockage is caused, the condition is unfavorable for full reaction and utilization of materials, and the yield of sodium cyanate finished products is reduced are solved.

Description

technical field [0001] The invention relates to the technical field of chemical production, in particular to a drying kettle for sodium cyanate production and a production process thereof. Background technique [0002] Sodium cyanate is a widely used raw material in the chemical industry. The existing synthesis of sodium cyanate mostly uses the urea method, which is to react urea and sodium carbonate to generate sodium cyanate and other products. For the production of sodium cyanate Reactors are mostly used for production at present. Reactor equipment mainly includes drying kettles and agitators. Materials are placed inside the reaction kettles and stirred and mixed with agitators to produce chemical reactions. At the same time, the heating device in the drying kettles is used to feed the The material is heated to promote the reaction. [0003] The existing drying kettle is generally installed outside the reaction kettle, and the kettle body is wrapped for heating, but ther...
