Filtration stage: separation of the filter cake and mother liquor of the product. The filter cake can be up to 500mm thick.
Washing stage: The filter cake is further purified, the residual mother liquor is washed and dehydrated. The filter cake and the washing liquid were mixed layer by layer by means of a lifting agitator, and finally formed into a slurry, and the suspension cake was sufficiently washed.
Drying stage: dewatering and drying of the filter cake. While the filter cake is being scraped loosely by the mixer, the side wall 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 quickly evaporates to achieve the drying effect. The evaporation speed is accelerated by the vacuum method in the device, and the evaporated moisture is taken away by adding the treated hot nitrogen medium to accelerate the drying of the material and improve the drying effect.
Unloading stage: The dry material is automatically discharged from the side discharge port through the reverse rotation of the S-type stirring slurry, and directly enters the package.
The filter washing and drying two-in-one three-in-one equipment can simultaneously replace the filtering and drying equipment (such as suction filter, pressure filter, double cone dryer, drying oven, etc.) in the same equipment to complete filtration, washing, drying, solid The whole process of unloading. Widely used in medicine, chemical, pesticide, food and other industries, it is the best equipment for filtration and drying. It can realize continuous operation and full-process continuous operation, and is more suitable for the production of aseptic products and toxic products.
