For removing the bur on foraminous conveyer；It falls grey collection device to be used for collecting the material being scattered, be scattered in Pellets in Drying Process
The material to get off is collected by the scraper plate being arranged below foraminous conveyer, is then passed through load displacing screw output and is collected dress into ash is fallen
It sets.Hot water can be exchanged heat by drying machine tail gas and be obtained, and realized that the recycling of thermal energy, water temperature are 50~60 DEG C, cleared up using hot water
Guipure can also mitigate the deformation that guipure is brought by frequent temperature change.Entire mesh dryer can be by 5~50mm of granularity, just
The pelletizing of beginning water content 6%~15%, dry to final water content≤1%, the drying effect of mesh dryer is good.
Pelletizing when being dried to the pelletizing on foraminous conveyer, is first passed through drying box by the 2, mesh dryer of the utility model
The blasting drying period drying of body obtains the uniform product of drying effect after being dried using down-draft drying zone, in foraminous conveyer
Soot cleaning system is set below traffic direction, transport collection is carried out to the material being scattered.The Hand scarf for the material that is scattered is realized, and
Cleaning effect more preferably, more thoroughly.
3, the mesh dryer of the utility model, the drying mode being combined using air blast and exhausting by the upper layer of pelletizing and
Lower layer is fully dry, while realizing that Hand scarf, final acquisition pulverization rate are low, dry to backhaul foraminous conveyer by soot cleaning system
The product of uniform in effect, while reducing bonding of the material to foraminous conveyer, improve the stability of equipment.
