Description

Technical Field

[0001] The utility model belongs to the technical field of biomass fuel pellet raw material preparation, and particularly relates to a cutting device for biomass fuel pellet raw material preparation. Background Technique

[0002] The cutting device for biomass fuel pellet raw material preparation is usually a part of a biomass granulator. In the working process of the biomass granulator, after the raw materials go through a series of compression and forming processes, they will finally be cut by a dedicated cutting device to form granular fuels with consistent lengths. Specifically, the cutting device in the biomass granulator is usually a fixed cutting knife. When the material is extruded into cylindrical pellets in the die holes, the cutting knife will cut according to the preset length to obtain granular fuels that meet the requirements. It should be noted that different biomass granulators may adopt different cutting devices and technologies, so the specific cutting device may vary depending on the equipment model and manufacturer. In practical applications, users should operate and maintain the cutting device correctly according to the equipment operation manual and maintenance guide to ensure its normal operation and extend its service life. In short, the cutting device for biomass fuel pellet raw material preparation is an important part of the biomass granulator, and it is responsible for cutting the formed pellet fuels into appropriate lengths to meet the production and use needs.

[0003] The cutting device for preparing biomass fuel pellet raw materials plays a crucial role in the production process of biomass fuel. Specifically, it has the following main functions: The raw materials for biomass fuel pellets are diverse, such as wood, crop straw, etc. These raw materials often need to undergo certain pretreatment, such as removing impurities and adjusting humidity, to ensure the quality of subsequent processing. The cutting device can cut the raw materials into appropriate sizes, facilitating subsequent processes such as crushing, drying, and forming. Through an automated cutting device, rapid and continuous cutting of the raw materials can be achieved, greatly improving production efficiency. In addition, the cutting device is usually equipped with an efficient conveying system, which can promptly convey the cut raw materials to the next process, reducing waiting time and further enhancing the overall production efficiency. The cutting device can precisely control the cutting size and shape of the raw materials, making the forming of pellets more uniform and stable during subsequent processing. This helps to ensure the quality stability and combustion performance of biomass fuel pellets. Biomass fuel, as a renewable energy source, its production and utilization are of great significance for promoting sustainable development. The cutting device, as one of the key equipment in the biomass fuel production process, its efficient and energy-saving design helps to reduce energy consumption and environmental pollution, conforming to the concept of green production. In summary, the cutting device for preparing biomass fuel pellet raw materials plays an indispensable role in the biomass fuel production process, and is of great significance for improving production efficiency, ensuring product quality, and promoting green production. The problems existing in the above technology are as follows: During the processing of biomass fuel pellets by the cutting device, a receiving box is required for receiving materials. However, there is a certain gap between the receiving box and the discharge port of the cutting device, and the cutting device cannot lift the receiving box to dock with the discharge port for use. Therefore, during the process of receiving biomass fuel pellets, due to the falling of the biomass fuel pellets from a height into the inner cavity of the receiving box, the cut biomass fuel pellets will be broken, making it inconvenient for users to stably receive the biomass fuel pellets. Summary of the Invention
