Description

A vertical ring die biomass pellet machine with a boring machine protection structure

technical field

The invention relates to the field of biomass granule production, in particular to a vertical ring die biomass granulator with a boring machine protection structure.

Background technique

Biomass pellet fuel is a clean and environmentally friendly energy. It is a rod-shaped pellet made of waste materials such as flowers, wood chips, and bark produced by furniture factories or wood factories. It achieves low-carbon emissions through full combustion, and is the goal of carbon neutrality. An important energy source for energy saving and emission reduction The fuel rod density after extrusion molding is several to ten times higher than that before molding, the burning time is long, and the thermal efficiency can be increased by 30%-40%.

Biomass pellet fuel is mostly produced by a pellet machine, which uses the principle of interaction between the extrusion force between the die plate and the pressure wheel and the friction force of the die hole to shape the material. There are two types of pellet machines, one is flat die pellet machine and the other is ring die pellet machine. The flat die pellet machine is suitable for pressing materials with strong cohesion, such as crop straw. The ring die pellet machine has strong pressure and is suitable for pressing materials with poor adhesion, such as wood chips;

Among them, sawdust, straw and other materials contain a certain amount of cellulose and lignin. Lignin is a structural monomer in the material, which belongs to the phenylpropane type polymer compound, and has the function of strengthening the cell wall and bonding cellulose; Under the action of pressure, the cellulose molecular clusters are dislocated, deformed, and extended, and the adjacent biomass particles inside are meshed with each other, recombined and pressed into shape, and the materials do not need to add any additives or binders during processing.

Since wood chips and straw are dry raw materials after drying, the moisture content of the raw materials is below 15%, which is different from other pellet products; such as feed pellet machines, because of the composition of oil or water, the humidity of raw materials is relatively high, and the raw materials have Certain fluidity; and dry sawdust and straw powder have poor fluidity, so it is easy to block the friction holes during the pressing and forming process, resulting in a dull phenomenon.
