Description

Technical Field

[0001] The utility model relates to the technical field of sawdust recovery, in particular to a device for improving the recovery rate of wood chips and sawdust. Background Art

[0002] A large amount of sawdust is generated during wood processing. Sawdust is plasticized and formed into semi-finished raw materials for mechanical charcoal through high temperature and high pressure in a rod making machine. Sawdust can also be made into compressed boards. These materials are now widely used in decoration and furniture. In fact, plywood, compressed boards, plywood, core boards and other materials are all made from wood sawdust and scraps. Sawdust can also be used as fuel for smoking food.

[0003] However, sawdust has different coarseness and fineness. For fuel use, only finer sawdust is needed to meet the demand, while larger sawdust can be made into compressed boards to improve utilization. If finer sawdust is mixed with larger sawdust as fuel without screening, the recycling rate of sawdust will be reduced. If it is screened manually using a sieve, the fine sawdust dust will form fine floating objects, which will affect your health if inhaled into the lungs. Utility Model Content
