Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of biomass fuel, especially relates to a forming pressure adjusting mechanism for biomass fuel production. BACKGROUND

[0002] Biomass fuel refers to solid, liquid or gaseous fuel made from organic matter (biomass) as raw material through physical, chemical or biological conversion. It is a renewable energy source, widely available and has carbon neutral potential (CO2 released during combustion can be reabsorbed by plants), and is considered as one of the alternatives to traditional fossil fuels.

[0003] Particle compression molding machine (also known as biomass pellet machine or pellet molding machine) is a kind of mechanical equipment which can compress loose biomass raw materials (such as sawdust, straw, rice husk, etc.) into high-density pellet fuel. The formed pellet is easy to store, transport and burn, and the calorific value is significantly improved. It is one of the key equipment for biomass energy utilization. The particle compression molding machine applies pressure to the material in the roller through the pressure roller, and extrudes the material into pellet strip through the forming hole on the roller. The larger the gap between the pressure roller and the roller, the smaller the pressure applied. It is suitable for larger materials and is not easy to cause material jam. The smaller the gap, the greater the pressure applied, which can make smaller materials more compact. However, the existing particle compression molding machine has a fixed installation of the pressure roller, which cannot adjust the gap distance between the pressure roller and the roller to adjust the pressure.

[0004] To solve the above problems, we propose a forming pressure adjusting mechanism for biomass fuel production. INVENTION CONTENTS
