I. Barium carbonate dryer - equipment overview


Barium carbonate, hexagonal fine crystal or white powder, hardly soluble in water. poisonous. Used in electronics, instrumentation, metallurgical industries. Preparation of fireworks, signal flares, ceramic coatings, accessories for optical glass. Also used as rodenticides, water clarifiers and fillers.

The strontium carbonate vacuum squeezing dryer comprises a motor and a motor reducer. The rotary shaft is connected to the rotating shaft, and the rotating shaft outer cylinder is provided with a plurality of stirring rod shafts. The top of the cylinder is provided with a feeding port, and the inlet end is connected and dry. The dust collector is connected to the wet dust collector, the wet dust collector is connected to the condenser, and the condenser is connected by the condensate tank condensate tank, which is connected by a vacuum pump, a vacuum pump and a steam separator. The above two heat carriers are opened into the cylinder, and the lower two heat carrier outlets of the cylinder. A solvent bottom hole is provided through the condensate tank.

The vacuum kneading dryer supplies the material to be dried into the cylinder through the inlet, and the motor drives the reducer to rotate, so that the driving shaft rotates in the opposite direction, the stirring rod is continuously stirred, the material is axially back and forth, and the cylinder is continuously updated with indirect steam. Heating the material in contact with the wall surface, stirring the stirring rod evenly, so that the surface moisture of the discharge material is more favorable, the evaporation of water and other solvents are sequentially passed through the dry dust remover and the wet dust remover.

The condensate in the condenser, the vacuum pump exits into the separator, and more air and water are separated. Condensate and other solvents are passed through the solvent condensate drain through the lower discharge process or reused. A heat carrier such as steam enters the cylinder liner through the heat carrier inlet and is discharged from the heat carrier outlet for recovery. The higher the self-operating vacuum, the greater the water vapor pressure of the surface of the dried material than the water vapor pressure in the evaporative drying cabinet space, which is beneficial to the discharge of dry water and surface moisture, which is beneficial to the drying of water molecules in the material to achieve drying. The purpose of the movement.
