The utility model is technical solution problem by the following technical programs: the drying device of the special wood powder of a kind of plastic-wood section, comprise support, machine barrel is provided with in described support, the upper surface of described support is closure plane, described closure plane is settled feed pot and exhaust outlet, the side fixed cycles cooler bin of described support, described circulating cooling case connects impurity preserving jar, the top connecting fan of described impurity preserving jar, bottom connecting fluid sealing groove, described frame bottom both sides are equipped with heating electric cabinet, described machine barrel is provided with interlayer, heat pipe is provided with in described interlayer, axostylus axostyle is provided with in described machine barrel, winding helical form heat pipe on described axostylus axostyle, described axostylus axostyle is connected with motor, the side of described machine barrel is provided with discharging box.
Described exhaust outlet is with negative pressure, by conduit series circulation cooler bin, impurity preserving jar and blower fan.Helical form condenser pipe is provided with in described circulating cooling case.
Described machine barrel is round tube shape structure, has the interlayer of outer wall and inwall formation, is provided with heat pipe in described interlayer, and the two ends of described heat pipe are connected with the oil pump in heating electric cabinet by pipeline.Make the wood powder near machine tube inner wall also can obtain heat energy, homogeneous heating.
Described axostylus axostyle is hollow-core construction, is fixed on the both sides of machine barrel, and the two ends of axostylus axostyle are connected with another oil pump heated in electric cabinet by pipeline.
The import of described axostylus axostyle and helical form heat pipe and outlet, and be connected with motor, rely on motor drive shaft bar to carry out reciprocating running, constantly stir the wood powder in machine barrel, the heating surface area of wood powder is increased greatly, ensures that wood powder is heated evenly.Avoid wood powder to be subject to the pollution of flue dust, so that the wood powder after drying is clean simultaneously.
Described helical form heat pipe is divided into inner heat-conductive pipe and outer heat pipe, and the diameter of described outer heat pipe is greater than the diameter of inner heat-conductive pipe.Fan blade type scraping blade inlayed by described outer heat pipe, described fan blade type scraping blade is made up of epoxy resin fiberglass plate, drive fan blade type scraping blade by heat pipe, avoid wood powder to be deposited on the charing causing wood powder bottom machine barrel, also make wood powder stir more even simultaneously.
The beneficial effects of the utility model can process wood powder fast and effectively, makes it more be applicable to plastic-wood section and use.Use through the obtained plastic-wood section of the wood powder of drying device process of the present utility model, compared with the plastic-wood section prepared with the wood powder before drying, mechanical property is more superior, and outward appearance is more attractive in appearance.The features such as cost is low, technique is simple, environmental protection, are applicable to suitability for industrialized production.
