Longxing Titanium Industry (870491), a new third board innovation layer company, added new patent information. The patentee is Longxing Titanium Industry, and the inventors are Zhao Yongchao, Cheng Fujian, Gao Jian, Wang Tianqi, Li Chaochao, and Wei Bingbing. The patent authorization date is July 18, 2023, and the patent name is "A Calcination Device for Improving the Specific Surface Area of Titanium Dioxide". The patent type is China Utility Model Patent, and the patent application number is CN202320462802.9.
The patent summary shows: The utility model relates to the field of titanium dioxide production equipment, in particular to a calcination device for improving the specific surface area of titanium dioxide. It comprises a furnace body, wherein the upper and lower ends of the furnace body are provided with electric heating pipes, and the left and right sides of the furnace body are provided with water-cooling components. The water-cooling components are provided with water inlet pipes and water outlet pipes extending outside the furnace body. Temperature sensors are arranged on the sides of the water-cooling components, and ventilation pipes are arranged on the left and right sides of the furnace body. The outer side of the furnace body is respectively provided with an air supply box and an exhaust box communicated with the ventilation pipes on both sides, and the air supply box is equipped with an induced draft fan. The utility model reduces the power of the electric heating tube and uses the water-cooling component and the induced draft fan to quickly cool the inside of the furnace body, and adjusts the power of the electric heating tube and the power of the induced draft fan according to the indications of the two sets of temperature sensors, thereby realizing temperature adjustment and precise temperature control, thereby increasing the specific surface area of titanium dioxide.
