Hot-air drying mode used by the present embodiment can form thermal shock to material, and then can be to avoid material in impeller slot 1804
The problem of interior caking fouling, ensures that the material after drying can be discharged out of drying cylinder 17 in time, and drying effect is splendid, in reality
In, when by the way that the filter cake that water content is 18-27wt% being dried with the drying machine of the present invention, hot air temperature 200
DEG C, the moisture deficit 5wt% of material after drying, obvious drying effect often handles 1 ton of filter cake, and power consumption is only 20 degree, uses
When only 0.6h, traditional spiral paddle drying machine and rake type drier are superior on drying effect and energy consumption.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement etc., should all be included in the protection scope of the present invention made by within refreshing and principle.
