Description

Technical Field

[0001] The utility model relates to the technical field of bio-dense fuel compression molding, in particular to a bio-dense fuel compression processing device which is convenient for molding. Background Art

[0002] The bio-densified fuel compression processing device is a device specially used to compress biomass raw materials such as agricultural and forestry waste, wood chips, and sawdust into shapes under specific temperature and pressure. Since biomass raw materials such as agricultural and forestry waste usually have a low bulk density and are loosely dispersed over a large area, this brings great difficulties to collection, transportation and storage. Therefore, through mechanical compression, the lignin in the biomass raw materials is softened and bonded with adjacent particles, thereby compressing to obtain a dense solid fuel with a certain shape and specification.

[0003] Existing biomass raw materials need to be crushed during compression molding. If the raw materials are not thoroughly crushed, their particles will be uneven in size or irregular in shape, which may lead to unstable fuel quality after compression molding and reduced combustion efficiency.

[0004] For example, a compression device for producing biomass pellet fuel is disclosed with announcement number CN213198914U. The biomass pellet fuel in this patent does not have a crushing mechanism to evenly crush the raw materials before being compressed by the first compression block and the second compression block. Due to the uneven size of the raw material particles, particles of different sizes are subjected to uneven force during compression, which may lead to reduced compression efficiency. It takes a longer time or greater pressure to achieve the expected compression effect. In addition, large particle raw materials may cause greater wear on the equipment during the compression process, shortening the service life of the equipment.

[0005] Therefore, it is necessary to invent a biomass fuel compression processing device that is easy to form to solve the above problems. Utility Model Content

Belts are tensioned on the No. 1 pulley and the No. 2 pulley, and the rotational power of the crushing roller is transmitted to the grinding roller by utilizing the transmission system consisting of the No. 1 pulley, the No. 2 pulley and the belt.
