Working principle of filter washing and drying equipment
The drying process consumes a lot of heat energy. The three-in-one filter, washing and drying machine, in order to save energy, some materials with high moisture content, suspensions or solutions containing solid substances are generally dehydrated mechanically or evaporated by heating, and then dried in the dryer. , filter the washing and drying machine three-in-one plant to get dry solids.
During the drying process, the transfer of heat and mass (moisture) needs to be completed at the same time. The three-in-one filter, washing and drying machine ensures that the partial pressure (concentration) of the moisture vapor on the surface of the material is higher than that of the moisture vapor in the external space, ensuring that the heat source The temperature is higher than the material temperature.
The heat is transferred from the high-temperature heat source to the wet material in various ways, so that the moisture on the surface of the material is vaporized and dissipated to the external space, so that there is a difference in the moisture content between the surface and the inside of the material.
The internal moisture diffuses to the surface and vaporizes, so that the moisture content of the material is continuously reduced, and the overall drying of the material is gradually completed.
Functional characteristics of filter washing and drying equipment
·Airtight operation
All processes are carried out in a closed container, without any leakage of materials and solvents, neither polluting the operating environment,
It can also protect the material from contamination
·No material and solvent loss
Complete process treatment in the same vessel, no material and solvent loss, which can minimize operating costs
·Excellent sealing system
The shaft seal between the stirring shaft and the container of the aseptic filter drier adopts a dry double-end mechanical seal plus a bellows
Side discharge valve adopts reliable metal-to-metal seal
With the function of self-cleaning sealing ring
Filtration washing and drying equipment is especially suitable for the treatment of difficult-to-filter slurry and flammable, toxic, volatile, and easily polluted materials. It integrates filtering, washing and drying operations in one machine. It has the characteristics of simplifying the process flow, improving production efficiency, preventing material pollution, convenient unloading, and easy realization of mechanical and electrical integration. At the same time, it can reduce the clean workshop area used in the entire production process. Substantial reduction, greatly reducing the basic investment cost of customers.
Realize the industrialization of key functional components for filtration, washing and drying equipment, laying the foundation for product upgrading of drying equipment; develop high-precision digital measuring instruments and knives for supporting medium and high-level drying equipment; implement advanced drying equipment demonstration projects to meet national key projects need.
