Particle cutting mechanism for biomass particle pelletizer

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 particle machinery, and specifically is a particle cutting mechanism for a biomass particle granulator. Background technique [0002] The total amount of biomass energy is 10 times the world's main energy fuel consumption, and the use of energy as an energy source is less than 1% of the total. Biomass energy can be used efficiently through biomass energy conversion technology. Biomass energy currently used mainly includes straw, firewood, grain hulls, animal manure, biological waste and organic waste residue, of which straw is the mainstay, with a total amount of 720 million tons. Equivalent to 360 million tons of standard coal, except 120 million tons as feed, the rest can be used as energy for papermaking, textiles and building materials. Reasonable development and utilization of biomass energy is a major strategic measure to solve the problem of energy and environmental pollution, and it has good environmen...

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
