Sawdust distillation column

The invention discloses a sawdust distillation column and relates to the technical field of natural resin extraction equipment. The sawdust distillation column comprises a column body provided with a feeding hole and a discharge hole and an upper sealing cover and a lower sealing cover which are respectively arranged on the feeding hole and the discharge hole. When the upper sealing cover and the lower sealing cover are respectively closed with the feeding hole and the discharge hole, an annular sealing unit is formed respectively at the junction of the upper sealing cover and the feeding hole as well as the junction of the lower sealing cover and the discharge hole. The annular sealing unit has an annular groove respectively clamped at the feeding hole and the discharge hole. A cavity which is communicated with the inside of the column body is arranged in the annular groove, and sawdust is arranged in the cavity. In comparison with the prior art, the invention has the advantage as follows: problems such as poor airtightness and high energy consumption of present sawdust distillation columns can be solved.
