Description

Technical Field

[0001] The utility model relates to the technical field of biomass power generation, and more specifically to a feeding structure of a fuel crusher for biomass power generation. Background Art

[0002] Biomass power generation is a technology that uses biomass energy to generate electricity. The technology of biomass power generation includes two main methods: direct combustion and gasification. Direct combustion is to burn biomass directly in a boiler to generate steam to drive steam turbines and generators to generate electricity, while gasification is to convert biomass into gas fuel in a gasifier. After purification, it directly enters the gas engine to burn and generate electricity or directly enters the fuel cell to generate electricity. Before combustion, the biomass will be crushed by a crusher to speed up the combustion, so the biomass also needs to be fed into the feeder.

[0003] After searching, the utility model patent with announcement number CN206474241U discloses a feeding system of a biomass power generation fuel crusher, including: a feeding mechanism, a crusher and a diesel engine, the crusher includes a frame and a roller mechanism, a pressure roller mechanism and a flying knife mechanism installed on the frame; the feeding mechanism, the roller mechanism, the pressure roller mechanism and the flying knife mechanism are connected in sequence; the diesel engine provides power output for the feeding mechanism, the roller mechanism, the pressure roller mechanism and the flying knife mechanism; the feeding mechanism conveys the biomass power generation fuel to the roller mechanism, which is dragged by the roller mechanism and sent to the pressure roller mechanism, and the biomass power generation fuel is rolled by the pressure roller mechanism to the flying knife mechanism, thereby completing the crushing of the biomass power generation fuel; this patent uses a diesel engine as a power source, which can ensure the stable feeding amount of the biomass power generation fuel crusher working in mountainous and forest areas with rugged roads and extremely poor power supply conditions, and realize quantitative transportation.

[0004] However, the above patents still have the following shortcomings: the conveyor belt is horizontal and has a certain height, and workers need to move the biomass fuel to a high place before putting it on the conveyor belt, which is not practical; and it can ensure that the materials on the conveyor belt are evenly distributed and transported to the crusher, causing the biomass entering the crusher to accumulate in one place for crushing, affecting the crushing efficiency. For this reason, we propose a fuel crusher feeding structure for biomass power generation. Utility Model Content
