Description

Technical Field

[0001] The utility model belongs to the technical field of sheet production and processing, and particularly relates to a dryer air box. Background Art

[0002] Wood chips refer to sawdust and planer shavings left during wood processing. They are mainly used as fuel and lightweight bone fillers, or are recombined into artificial boards, and can also be used as papermaking raw materials. When using wood chips to make various products, the wood chips need to be dried first to reduce their moisture content to the required range before the next manufacturing process can be carried out. For the drying of wood chips, the traditional method is natural drying, where the wood chips are placed in the outdoor sun for natural drying to evaporate the moisture in the wood chips; although this natural drying has low cost and is relatively simple to operate, it takes a long time and requires a large area for drying; therefore, it is greatly affected by natural conditions and has poor stability, and the amount of wood chips dried each time is not large, which cannot meet the large-scale production and processing requirements. Currently, the commonly used drying method is to put the wood chips into a dryer and dry the wood chips with hot air, but the current dryer has problems such as uneven and insufficient drying of wood chips, low drying efficiency, and poor drying effect.
