Technical Field

[0001] This utility model belongs to the field of biomass storage and transportation technology, and relates to an automatic control system for biomass storage and transportation. Background Technology

[0002] Biomass storage and transportation refers to the process of centrally collecting dispersed biomass resources (such as crop straw, forestry waste, and energy plants) and safely and efficiently transporting them from the production site or collection point to biomass energy utilization facilities (such as biomass power plants and biomass boilers) through appropriate storage and transportation methods. Manual labor is inefficient, while existing biomass storage and transportation equipment is complex, expensive, and inconvenient for subsequent maintenance, thus increasing operating costs.

[0003] Therefore, an automatic control system for biomass storage and transportation is designed to overcome the above problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide an automatic control system for biomass storage and transportation that is simple and reasonable in structure, low in cost, practical and safe, stable in operation, and convenient for transportation.

[0005] This utility model is achieved through the following technical solution: an automatic control system for biomass storage and transportation, comprising a biomass crushing zone, a biomass feeding zone, and a boiler. After the biomass raw materials are fed into the biomass crushing zone by a loader, they are crushed. The crushed biomass fragments are then fed into the biomass feeding zone by the loader and then transported to the boiler. The biomass crushing zone consists of a biomass crusher and a belt conveyor. After the biomass raw materials are fed into the inlet of the biomass crusher for processing by the loader, they are discharged from the outlet of the biomass crusher onto the conveyor belt of the belt conveyor and transported to the loader's hopper. The loader then transports the biomass fragments to the biomass feeding zone for further processing.

A shaftless feeder is installed between the biomass receiving bin and the belt conveyor, as well as between the belt conveyor and the biomass discharge pipe. The biomass fragments loaded in the loading truck's bucket are fed into the inlet of the biomass receiving bin via the crane's grab bucket. The outlet of the biomass receiving bin is directly opposite the shaftless feeder. The biomass fragments are then conveyed by the shaftless feeder onto the belt conveyor, transported to the shaftless feeder between the belt conveyor and the biomass discharge pipe, and then conveyed to the biomass discharge pipe.
