Vertical drier's structure:

The vertical dryer adopts vertical equipment and steel structure housing, the lining is equipped with heat preservation material to keep warm, in the inner of the kiln, and multilayer high temperature castings have been used and overlapped. In the higher, middle and lower parts, all relevant components have several groups of vibrate, closure, temperature control and intelligent control systems. Water vapor and smoke collected and removed by the whirlwind dust collector installed in the draught fan.

Vertical drier''s principle:

The key technology of vertical dryer is to control the flow rate and residence time of the material in every area of the dryer, making the hot flue gas fully convected, radiated and heat conducted with the material which thus can be scattered in the dryer as far as possible to enlarge the contact area between the hot smoke and the material. At the same time, material drying parameter optimization microcomputer software technology has been adopted to proceed online detection to the material moisture and gas temperature in the preheating zone, stoving zone and drying zone, and adjust the system parameters on line such as heating ability, lead-wind quantity, secondary hot wind distribution, heat supply capacity, material closure capacity and retention time,etc., realizing dynamic optimization balance of the system and improving the heat utilization rate.

When the temperature control instrument on the bottom of the kiln shows that the temperature reaches 400 °C to 500 °C, the intelligent resistance twist-action material place controller will give instructions to the elevator to lift the materials less than or equal to 25 mm to the preheating zone to preheat. When the temperature control instrument at the top of the kiln shows 150 °C to 250 °C, the electric closure device automatically begins measuring and feeding, and the materials flow into the cross vibrate chute for the secondary preheating and drying. In the process of preheating and vibrating, the materials become loose naturally and then evenly go into several groups of inter-overlapping material stacks. When the third drying came, the materials come down from the higher place to the lower, and repeatedly precede thermal radiation transmission with the inter-overlapped metal in several groups of bulk material stacks, then mutually exchange with the continuously rising heat flow. The moisture volatilizes gradually, and the materials go into the high temperature funnel for drying to make the materials completely out of the water. When humidity measurement instrument sends the desired value signal, the material will be automatically discharged, be output and laid up by conveying equipment.
