Filtration stage: separation of product filter cake and mother liquor. The thickness of the filter cake can reach 500mm.
Washing stage: the filter cake is further purified, the remaining mother liquor is washed and dehydrated. The filter cake and the washing liquid are mixed layer by layer through the lifting agitator to form a slurry, and the suspension filter cake is fully washed.
Drying stage: the filter cake is dehydrated and dried. While the filter cake is scraped and loosened layer by layer by the agitator, the side walls of the equipment, the bottom of the filter plate, and the moving stirring blade heat the filter cake at the same time, and the moisture is quickly evaporated to dryness The efficiency of the product is to accelerate the evaporation speed through the method of vacuum in the equipment, and the evaporated moisture is taken away by adding the treated hot nitrogen and other media to accelerate the drying of the material and improve the drying efficiency.
Unloading stage: The dry material is automatically discharged from the side discharge port through the reversal of the S-shaped stirring blade and directly enters the packaging.
The "three-in-one" equipment for filtering, washing and drying can simultaneously replace filtering and drying equipment (such as: suction filter, filter press, double cone dryer, drying oven, etc.) in the same equipment to complete filtering, washing, drying, The whole process of solid discharge. Used in chemical, food and other industries, it is a filtering and drying equipment. It can realize fully enclosed and continuous production in the whole process.
