TECHNICAL FIELD
[0001] The utility model relates to the technical field of biomass pellet production, and specifically relates to a pair roller type biomass pellet machine. BACKGROUND
[0002] Biomass fuel refers to a new type of clean fuel that uses biomass material combustion, and generally mainly includes agricultural and forestry waste such as straw, sawdust, sugarcane residue and rice chaff. During the production and processing of the biomass fuel, a pellet machine is needed to extrude and form the waste. The pair roller type biomass pellet machine extrudes and forms the material by the relative rotation of two extrusion rollers.
[0003] After searching, the existing patent (publication number: CN109647286A) discloses a pair roller biomass coal pellet machine, which belongs to the field of biomass coal forming and includes a rack, a pair roller forming mechanism on the rack, and a driving mechanism for providing power for the work of the pair roller forming mechanism. The biomass coal pellet machine adopts a double-roller relative rotation extrusion forming structure. The flanges and grooves on the two rollers are staggered to extrude the two rollers relative to each other, realize the forming of biomass fuel, and no longer use a cantilever shaft. The structure is reasonably stressed. Since the roller is a self-rotating structure, the bearing is fixed to the box and is in a relatively static working state. The bearing can be continuously cooled by cooling oil to avoid rapid reduction of the service life of the bearing in a high-temperature environment. The roller adopts the setting of the flange and the groove and the herringbone grooves on the flange surface to increase the flow of the biomass raw material during the rolling process and reduce the adhesion of the biomass raw material to the flange of the roller. The material is in a flowing state and enters the forming die, thereby improving the effective utilization rate of energy.
[0004] However, in the above-mentioned scheme, the distance between the two extrusion rollers is fixed and cannot be adjusted according to actual production needs. In actual production, the distance between the two extrusion rollers needs to be reasonably adjusted according to production needs, product quality, and different material processing. An unreasonable distance will affect the density and uniformity of the pellets and cause excessive wear of the equipment, thereby affecting the normal, efficient, and safe operation of the equipment.
