Technical Field

[0001] The invention relates to the technical field of environmentally friendly energy manufacturing, in particular to a biomass particle granulation core. Background Art

[0002] Biomass pellet fuel is an innovative clean energy, which is mainly composed of agricultural and forestry waste. After a series of processing processes such as crushing, mixing, compression and drying, we get a variety of pellet fuels that can be used immediately, which can be burned directly.

At the same time, the production efficiency of this type of equipment is relatively low, and in actual use, it is often impossible to accurately control the length of the finished pellets. In addition, in actual application scenarios, biomass materials are usually placed directly into the equipment, crushed by a grinding disc, and then extruded, which makes the entire process inefficient.

[0011] Preferably, a scale mark is provided on the side of the ferrule.

[0012] Preferably, a special-shaped groove is provided at the top of the rotating shaft, a special-shaped block is fixedly connected to the bottom end of the flange plate 1, the special-shaped block matches the model and specification of the special-shaped groove, a bolt 4 is inserted at the top of the flange plate 1, and the bottom end of the bolt 4 is threadedly connected to the bottom of the special-shaped groove.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This biomass pellet making machine core prevents the end of the bolt from tightly contacting the inner wall of the ferrule by loosening the bolt one, thereby relieving the friction between the bolt one and the ferrule.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] Biomass pelletizing is the process of making biomass raw materials into granular fuel through compression molding technology. This process is of great significance for improving the utilization efficiency of biomass energy, reducing environmental pollution and promoting the development of renewable energy. The following are the main reasons for biomass pelletizing:

[0037] Improve combustion efficiency: Biomass pellet fuel has a higher density and uniformity, which makes the combustion more complete and improves the heat conversion efficiency; the combustion characteristics of pellet fuel are better than those of raw biomass, reducing incomplete combustion and smoke generation. Easy to store and transport: Pellet fuel is small in size and high in density, which is convenient for storage and long-distance transportation, reducing logistics costs; compared with bulk biomass, pellet fuel is not easy to absorb moisture during storage and maintains good stability. Reduce environmental pollution: Biomass pellet fuel produces less harmful gases during combustion, which helps to reduce greenhouse gas emissions and air pollution; using biomass pellet fuel to replace traditional fossil fuels such as coal can significantly reduce the emission of pollutants such as SO2 and NOx. Improve energy security: As a renewable energy source, biomass pellet fuel helps to reduce dependence on external energy and improve the security of energy supply; the wide distribution and renewability of biomass resources make biomass pellet fuel a sustainable energy option. Promote economic development: The production and use of biomass pellet fuel can create employment opportunities and promote local economic development; the development of the biomass pellet fuel industry can drive the development of related industrial chains, such as biomass collection and processing equipment manufacturing. Improve rural energy structure: Biomass pellet fuel can be used as a clean energy source in rural areas to improve the living conditions and energy structure of rural residents; the use of biomass pellet fuel can reduce the dependence on firewood in rural areas and help protect forest resources. Improve energy efficiency: The energy density of biomass pellet fuel is higher than that of raw biomass, which improves the utilization efficiency of biomass energy; the standardized production of pellet fuel helps to improve the compatibility and operation efficiency of combustion equipment. Adapt to diverse sources of raw materials: Biomass pellet fuel can use a variety of agricultural and forestry wastes as raw materials, which increases the diversity of raw materials; different types of biomass raw materials can be converted into high-quality pellet fuels through different pretreatment technologies. In addition, when selecting and using biomass pellet fuel, the following factors need to be considered to ensure the best effect: Raw material selection: Select biomass raw materials suitable for pelletizing, such as sawdust, straw, etc., and ensure that the raw materials are dry and clean. Pellet quality: Pay attention to the physical and mechanical properties of the pellets, such as durability, density, etc., to ensure combustion efficiency and storage stability. Environmental protection standards: Ensure that the production and use of biomass pellet fuels meet local environmental protection standards and regulatory requirements. Economic benefits: Evaluate the economic feasibility of biomass pellet fuel, including production costs, transportation costs, and competitiveness with traditional energy sources.

[0038] In general, the purpose of biomass pelletizing is to improve the utilization efficiency of biomass energy, reduce environmental pollution, promote the development of renewable energy, and bring both economic and social benefits. With the advancement of technology and policy support, biomass pellet fuel will play an increasingly important role in the future energy market.

[0039] The current pellet forming device has a very complex internal structure, which makes its maintenance process lengthy. In particular, the pellet production equipment, which is the core component, generally adopts rolling pressing technology. Since it contains a large number of rotating parts, the possibility of failure is relatively high. In addition, the manufacturing speed of this type of equipment is low, and it is difficult to accurately control the length of the pellet product in actual use. In addition, in the use environment, biomass materials are usually directly put into the equipment, crushed by disc grinding, and then squeezed, which makes the overall operation efficiency low. Among them, the four-roller granulator and the three-roller granulator both need to level the rollers. The steps for adjusting the rollers are very delicate and complicated, which will directly affect the degree of pellet forming. In addition, when granulating biomass materials, the process requirements for the four-roller granulator and the three-roller granulator are generally high, and it is difficult to align the rollers, which affects the processing of the finished product.
