Hot pressing equipment for biomass pellet fuel production

Abstract

This utility model discloses a hot-pressing molding equipment for biomass pellet fuel production, including a frame. An extrusion mechanism is located at the top of the frame, and a heating mechanism is located on the outside of the extrusion mechanism. A pressing mechanism is located at one end of the extrusion mechanism. The pressing mechanism includes a mounting frame, a pressing sleeve, a cover plate, a hydraulic rod, and a pressing cylinder. A discharge mechanism is located at the bottom of the pressing sleeve. The pressing mechanism, in conjunction with the extrusion and heating mechanisms, heats and extrudes the material. The side wall of the pressing cylinder continues to seal the discharge port of the extrusion mechanism, allowing the material to be further compressed inside the extrusion mechanism, thus maximizing the removal of gas from the material. The pressing of the material by the bottom of the pressing cylinder reduces the bubble content in the formed biomass pellet fuel, improves the stability of the formed pellets, and prevents excessive breakage of the biomass pellet fuel.

The servo motor 230 drives the drive shaft 231 to rotate, which in turn drives the screw conveyor 240 to rotate. The screw conveyor 240, in conjunction with the extrusion cylinder 220, extrudes and transports the material. During this process, multiple heating controllers 320 and heating rings 330 work together to heat the extrusion cylinder 220 in stages, thereby heating the material inside the extrusion cylinder 220.
