Abstract

The invention discloses a granulation and crystallization device used in a sodium metasilicate preparation process, and relates to the technical field of sodium metasilicate production equipment.The granulation and crystallization device comprises a crystallization tank, a discharging mechanism, a granulation and crystallization mechanism and a wall scraping mechanism, a motor is arranged at the top end of the crystallization tank, and a slag discharging pipe is arranged at the bottom end of the crystallization tank; a slag discharging valve is arranged on one side of the outer wall of the slag discharging pipe, and a cooling liquid inlet pipe, a stock solution feeding pipe and a seed crystal feeding pipe are arranged on one side of the outer wall of the crystallizing tank. By arranging the crystallizing tank, the crystallizing bin, the motor, the filter plate, the water suction cylinder, the water suction groove hole, the rotating shaft, the spiral blade, the first connecting rod, the stirring rod, the second connecting rod, the vertical scraper, the stock solution feeding pipe and the seed crystal feeding pipe, quick separation of crystallized particles can be achieved, and the working efficiency of sodium metasilicate crystallization is effectively improved.

Description

technical field [0001] The invention relates to the technical field of sodium metasilicate production equipment, in particular to a granulation and crystallization device used in the preparation process of sodium metasilicate. Background technique [0002] Sodium metasilicate is crystalline, with a relative bulk density of 0.8-1.0g / ml, a melting point of 72.2°C, and a relative molecular weight of 212. It is easily soluble in water and dilute lye, insoluble in alcohol and acid, and its aqueous solution is alkaline. It is easy to absorb moisture and deliquescence, has strong decontamination ability, large PH buffering capacity, and has good detergency, emulsification, dispersion, wetting, penetration and other properties. [0003] Sodium metasilicate can be used as a washing aid to replace sodium tripolyphosphate (STPP) in the production of phosphorus-free and low-phosphorus detergents. As the main raw material of the aid, it is used for cooking, bleaching, and so on in the pr...
