Abstract
The utility model relates to a drying apparatus, in particular to a spray dryer for drying slurry materials or molding powdered materials; the spray dryer comprises a tower body, a blowing part, a feeding part and a collecting part; and the blowing part comprises a blower and a high-power electric heater. Through the spray dryer, a steam heater in the existing heater is removed, and the high-power electric heater is used, so that the heating effect can not be influenced because of unstable air pressure of a steam source in heating process, thereby improving the heating speed and evaporating efficiency so that the product is vaporized according to the design demands, and the purity and the water content of product are ensured.
Description
Technical field
The utility model relates to a kind of drying equipment, particularly a kind of spray dryer that is used for to slurry drying or powder moulding.
Background technology
Spray dryer is mainly used to slurry drying or powder moulding.Existing spray dryer structure is made up of tower body 1, air-supply part 2, feeding part 3 and collection part 4 as shown in Figure 1.Wherein, the tower body top is equipped with hot-air distributor and atomizer, and stretch out under hot-air distributor the atomizer lower end.The air-supply part contains pressure fan 2-1 and heater.Heater contains steam heater 5 and electric heater 2-2, and the steam inlet 5-1 of steam heater 5 connects vapour source, and the outlet of steam heater 5 is connected with the import of electric heater 2-2.When adopting this spray dryer that rare earth oxide is carried out drying, because steam heating time is long, influence adds thermal effect when vapor pressure is unstable, thereby cause that product can not evaporate by designing requirement, drying, the water content height of product, glutinous easily bucket wall, yield is low.Adopt steam heater in addition, because vapours is to the erosion of electric heater, the service life of electric heater is influenced, and has little metal impurity in the use and sneak in the material in the tower body, influences the purity of product.
The utility model content
The technical problems to be solved in the utility model is: when solving existing spray dryer rare earth oxide being carried out drying, because steam heating time is long, influence adds thermal effect when vapor pressure is unstable, thereby cause product not evaporate by designing requirement, the water content height of product, purity is undesirable, glutinous easily bucket wall, the technical problem that yield is low, the utility model provides a kind of spray dryer, it adopts the large power, electrically heater, has improved firing rate and evaporation efficiency, has guaranteed the purity and the water content value of product.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of spray dryer, and comprise tower body, air-supply part, feeding part and collect part, the air-supply part contains pressure fan and heater, and heater is an electric heater.
Further, for reaching the desirable thermal effect that adds, the titanium alloy electrically heated rod that it is 63KW that described electric heater has 21 power.
The beneficial effects of the utility model are: spray dryer of the present utility model, removed the steam heater in the existing heater, adopt the large power, electrically heater, heating process can not add thermal effect because of unstable influence of the air pressure of vapour source, firing rate and evaporation efficiency have been improved, product can be evaporated by designing requirement, guaranteed the purity and the water content value of product.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of existing spray dryer.
