Pellet cutting mechanism for biomass pellet granulator

Abstract

A particle cutting mechanism for a biomass particle pelletizer comprises a cover, a scraper and a scraper driving device, wherein a first through hole is formed at the bottom of the barrel-shaped cover; the internal diameter of an open end of the barrel-shaped cover is greater than the external diameter of a ring mold of the biomass particle pelletizer; the scraper driving device comprises a motor, a bull gear and a plurality of bull gear connecting rods; the bull gear connecting rods are connected to the bottom of the barrel-shaped cover; a T-shaped roll shaft is connected with the tail end of each connecting rod; a second through hole is formed in the center of the bull gear; the diameter of the second through hole is not less than that of the first through hole; an annular groove with an inverted T-shaped cross section is formed on one side of the gear; the T-shaped roll shafts are embedded into the annular groove and connected with the annular groove in a sliding manner; the scraper is connected onto the other side of the bull gear and rotates between an external wall of the ring mold of the biomass particle pelletizer and an internal wall of the barrel-shaped cover with the bull gear; a track of a cutting edge of the scraper is annular; and the annular track corresponds to a position of the external wall of the ring mold of the biomass particle pelletizer.

Description

technical field [0001] The technical solution belongs to the field of granule machinery, in particular to a granule cutting mechanism for a biomass granulator. Background technique [0002] The total amount of biomass energy is 10 times that of the world's main energy fuel consumption, and the energy utilization is less than 1% of the total amount. Biomass energy can be efficiently utilized through biomass energy conversion technology. Biomass energy currently used mainly includes straw, firewood, grain husk, poultry manure, biological waste and organic waste, among which straw is the main one, with a total amount of 720 million tons. Equivalent to 360 million tons of standard coal, excluding 120 million tons as feed, the rest of paper, textile and building materials can be used as energy. Rational development and utilization of biomass energy is a major strategic measure to solve energy and environmental pollution problems, and has good environmental and economic benefits....

Problems solved by technology

In production practice, it is found that the size of the naturally fractured material particles is uneven, and the degree of combustion is prone to unevenness in the later combustion and use. Even some of the particles added in the same batch burn completely, producing little ash, while some particles are not There are still intact unburned fibers in the middle
