Problems solved by technology

Among them, sedimentation dehydration in sedimentation tanks is mostly used in small-scale concentrators, and is suitable for dehydration of iron concentrates with a particle size of less than 50 mesh. Although the production cost of this method is low, the settling time is long, and it is difficult for the particle size to be less than 50 mesh. Large-scale concentrators generally use filter press equipment for dehydration. The dehydration index of filter press method is good, but the equipment investment is large, the production cost is high, and because the filter screen and other components are easy to be blocked and damaged, they need to be shut down for repair and replacement, so the production continuity is poor.

Abstract

The invention discloses a vertical dryer, which comprises a feed hopper (1), a stand (2), a rotary conveying chamber (3), a driving motor (4), a discharge port (5) and an internal fixation drying chamber (6), and is characterized in that: a plurality of grooves (9) for circulating hot air are formed on cylindrical surfaces of a shell (8) of the rotary conveying chamber and a shell (12) of the internal fixation drying chamber. Compared with the prior art, the vertical dryer has the advantages of simple structure, low energy consumption and high dehydration efficiency.

Description

technical field [0001] The invention relates to a drying device, in particular to a vertical dryer for drying iron concentrate. Background technique [0002] Iron ore becomes iron ore concentrate product after processing and water separation. There is a large amount of interstitial water between the ore sand particles. If dehydration is not done, the iron sand is easy to lose with the water during transportation, which will cause losses to the enterprise and pollute the environment on the way. In the prior art, when the iron ore concentrate is dehydrated, sedimentation and dehydration in a sedimentation tank is usually used, or filtration and dehydration is performed using a filter press device. Among them, sedimentation dehydration in sedimentation tanks is mostly used in small-scale concentrators, and is suitable for dehydration of iron concentrates with a particle size of less than 50 mesh. Although the production cost of this method is low, the settling time is long...
