Abstract

The invention provides a three-layer biomass extrusion moulding device, which comprises an upper layer extrusion moulding device, a middle layer extrusion moulding device and a lower layer extrusion moulding device, wherein the upper layer extrusion moulding device, the middle layer extrusion moulding device and the lower layer extrusion moulding device are arranged in sequence from top to bottom; any one of the extrusion moulding devices consists of a pressure roller mechanism and a flat-die plate arranged at the bottom part of the corresponding pressure roller mechanism; axes of the flat-die plates a, b and c are coincident; two rows of die holes are distributed in each flat-die plate by taking the circle center of the corresponding flat-die plate as the datum; the lower port of each die hole forms a discharge hole. A vertical main shaft is also arranged in a vertical biomass extrusion moulding machine with the three-layer biomass extrusion moulding device; the vertical main shaft consists of an upper shaft and a lower shaft; the upper shaft is sheathed with the flat-die plates in the upper layer extrusion moulding device, the middle layer extrusion moulding device and the lower layer extrusion moulding device; the lower shaft is arranged on a rack in an upper and lower two-point support bearing configuration manner. Extrusion moulding can be performed on a biomass material for three times by the three-layer biomass extrusion moulding device provided by the invention, and therefore, the extrusion moulding effect of the material is improved. Moreover, the extrusion moulding efficiency of the biomass material also can be improved.

Description

technical field

[0001] The invention relates to a biomass extrusion molding device, in particular to a three-layer biomass extrusion molding device and a vertical biomass extrusion molding machine. Background technique

[0002] There are two main designs of the existing biomass extrusion molding machines, one is the ring die machine with the mold plate placed vertically, which is characterized in that the forming die holes are evenly distributed along the circumferential direction; the other is the flat die machine with the mold plate placed flat The mold machine is characterized by single or multiple rows of forming die holes evenly distributed along the shaft diameter. Both of these forming machines form the desired extruded product by extruding the material from these forming holes. The disadvantage is that for materials such as bulk materials (such as sawdust), wheat straw, rice husk, and corn stalks in the northeast, it is difficult to extrude and form when they are in...
