Description

Technical Field

[0001] The utility model relates to the technical field of biomass fuel, in particular to a biomass fuel extrusion molding device. Background Art

[0002] Biomass fuel: refers to the burning of biomass materials as fuel, generally mainly agricultural and forestry waste (such as straw, sawdust, bagasse, rice bran, etc.), which is mainly different from fossil fuels; under current national policies and environmental protection standards, direct combustion of biomass is a high-pollution fuel and is only used in large stoves in rural areas and is not allowed in cities.

[0003] For example, a biomass fuel extrusion molding device with the authorization announcement number "CN210453889U" only needs to use one motor to make two punches drive two punches to move back and forth in two punch barrels, thereby extruding the fuel. It has low cost and reduces failure points, and is suitable for large-scale promotion and use. However, this biomass fuel extrusion molding device uses two punches to drive two punches for extrusion molding. Since the punches move back and forth, they cannot feed all the time and cannot be processed continuously. It takes a long time to extrude all the biomass fuels, which reduces work efficiency. At the same time, since the discharge port of the punch barrel is fixed, when it is necessary to extrude biomass fuels of other diameters according to demand, the operator needs to switch to other compatible machines for processing, which increases work limitations.

[0028] Working principle:

[0029] Preparation process:

[0030] First, the operator selects a suitable discharge plate 4 according to the diameter of the biomass fuel to be extruded, and then the operator turns the upper handle 702 clockwise. The rotation of the handle 702 drives the third gear 703 to rotate, thereby driving the rack 704 to move along the surface of the fixed column 705, thereby compressing the spring 706.

Then the operator slowly turns the two handles 702 in the opposite direction to make the surface of the rack 704 press against the inner wall of the groove processed on the discharge plate 4, so that biomass fuels of different diameters can be processed, thereby reducing work limitations.

[0031] Biomass fuel extrusion molding process:

[0032] First, start the hydraulic cylinder 202.
