Biomass raw material granulating and forming device

Abstract

The invention discloses a biomass raw material granulating and forming device, and relates to the technical field of biomass processing. The device comprises a base, supporting rods are arranged on the upper surface of the base in an annular array mode, and a cylinder is fixed to the top ends of the supporting rods; an extrusion plate is arranged in the cylinder; a rotating shaft is rotationally connected between the bottom end and the top end of the cylinder; a connecting seat is fixed at the top of the rotating shaft; rolling sleeves sleeve the peripheral side surfaces of the two ends of theconnecting seat; a rectangular box is arranged at the top of the cylinder; two crushing rollers are rotationally connected between the opposite faces of the inner sides of the rectangular box. A material guide cylinder is arranged on one side of the rectangular box; and a material guide frame is rotationally connected between the end part of the material guide cylinder and the rectangular box. Raw materials are conveyed through the material guide frame, the two crushing rollers crush the raw materials for the first time, the rotating shaft rotates the connecting seat to enable the rolling sleeves to roll annularly to crush the raw materials for the second time, the uniformity of biomass particles after granulation is guaranteed, the extrusion plate is prevented from being blocked in the raw material extrusion process, and the actual use requirement is met.

Description

technical field [0001] The invention belongs to the technical field of biomass processing, in particular to a biomass raw material granulation molding device. Background technique [0002] my country is a big energy-consuming country, so adjusting the energy structure and using biomass energy is an inevitable choice. Biomass pellets are processed by cold-state compaction of pulverized biomass straw, forestry waste and other raw materials by using pressing rollers and ring dies under normal temperature conditions, and their volume is greatly reduced, making it easier to transport, store and use. The key problem of large-scale utilization of biomass is very suitable for biomass power generation, clean energy transformation of industrial boilers, new cooking fuels in rural areas, and greatly improves the combustion performance of biomass. [0003] Chinese patent CN205672878U (Application No.: CN201620581774.2) discloses a "ring die granulator". In its embodiment, the feeder, f...
